Abstract
The co-occurrence of cancer and heart failure (HF) represents a significant clinical drawback as each disease interferes with the treatment of the other. In addition to shared risk factors, a growing body of experimental and clinical evidence reveals numerous commonalities in the biology underlying both pathologies. Inflammation emerges as a common hallmark for both diseases as it contributes to the initiation and progression of both HF and cancer. Under stress, malignant and cardiac cells change their metabolic preferences to survive, which makes these metabolic derangements a great basis to develop intersection strategies and therapies to combat both diseases. Furthermore, genetic predisposition and clonal haematopoiesis are common drivers for both conditions and they hold great clinical relevance in the context of personalized medicine. Additionally, altered angiogenesis is a common hallmark for failing hearts and tumours and represents a promising substrate to target in both diseases. Cardiac cells and malignant cells interact with their surrounding environment called stroma. This interaction mediates the progression of the two pathologies and understanding the structure and function of each stromal component may pave the way for innovative therapeutic strategies and improved outcomes in patients. The interdisciplinary collaboration between cardiologists and oncologists is essential to establish unified guidelines. To this aim, pre-clinical models that mimic the human situation, where both pathologies coexist, are needed to understand all the aspects of the bidirectional relationship between cancer and HF. Finally, adequately powered clinical studies, including patients from all ages, and men and women, with proper adjudication of both cancer and cardiovascular endpoints, are essential to accurately study these two pathologies at the same time.

Abstract
Checkpoint inhibitors have revolutionized cancer treatment. However, only a minority of patients respond to these immunotherapies. Here, we report that blocking the inhibitory NKG2A receptor enhances tumor immunity by promoting both natural killer (NK) and CD8+ T cell effector functions in mice and humans. Monalizumab, a humanized anti-NKG2A antibody, enhanced NK cell activity against various tumor cells and rescued CD8+ T cell function in combination with PD-x axis blockade. Monalizumab also stimulated NK cell activity against antibody-coated target cells. Interim results of a phase II trial of monalizumab plus cetuximab in previously treated squamous cell carcinoma of the head and neck showed a 31% objective response rate. Most common adverse events were fatigue (17%), pyrexia (13%), and headache (10%). NKG2A targeting with monalizumab is thus a novel checkpoint inhibitory mechanism promoting anti-tumor immunity by enhancing the activity of both T and NK cells, which may complement first-generation immunotherapies against cancer. Blocking NKG2A unleashes both T and NK cell effector functions Combined blocking of the NKG2A and the PD-1 axis promotes anti-tumor immunity Blocking NKG2A and triggering CD16 illustrates the efficacy of dual checkpoint therapy

Abstract
PURPOSE The prognosis for women with recurrent and metastatic endometrial cancer is poor, and improved therapies are needed. The mammalian target of rapamycin (mTOR) pathway is an important target, and mTOR inhibitors show clinical activity in endometrial cancer. PATIENTS AND METHODS An open-label, multicenter, randomized, phase II trial of oral ridaforolimus compared with progestin or investigator choice chemotherapy (comparator) was undertaken in women with metastatic or recurrent endometrial cancer who had progressive disease following one or two lines of chemotherapy and no hormonal therapy. The primary end point was progression-free survival (PFS) assessed by independent radiologic review. RESULTS One hundred thirty patients were enrolled (64 received ridaforolimus and 66 received the comparator), and median age was 66 years. Treatment discontinuation as a result of adverse events was 33% with ridaforolimus versus 6% with the comparator, with common (> 10%) grade 3 toxicities being hyperglycemia, anemia, and diarrhea. Thirty-eight percent (ridaforolimus) versus 71% (comparator) of patients discontinued treatment as a result of disease progression. Median PFS at the protocol prespecified interim analysis with 58 PFS events (primary end point) was 3.6 months (95% CI, 2.7 to 7.3 months) for ridaforolimus and 1.9 months (95% CI, 1.9 to 2.3 months) for the comparator (hazard ratio, 0.53; 95% CI, 0.31 to 0.90; P = .008). PFS rate for ridaforolimus versus comparator was 48% versus 18% at 16 weeks and 38% versus 15% at 24 weeks. Objective response rate for ridaforolimus versus comparator was 0% versus 4% (P = .925), and stable disease was achieved in 35% versus 17% of patients (P = .021). CONCLUSION Oral ridaforolimus shows encouraging activity in advanced endometrial cancer but is associated with significant toxicity. Inhibition of the PI3K/Akt/mTOR pathway may be a viable therapeutic target.

Abstract
BACKGROUND Ridaforolimus is an inhibitor of mTOR with evidence of antitumor activity in an I.V. formulation. This multicenter, open-label, 3 + 3 design nonrandomized, dose-escalation, phase I/IIa trial was conducted to determine the safety, pharmacokinetic (PK) and pharmacodynamic parameters, maximum tolerated dose, and antitumor activity of oral ridaforolimus. PATIENTS AND METHODS Patients with metastatic or unresectable solid tumors refractory to therapy were eligible. Seven different continuous and intermittent dosing regimens were examined. RESULTS One hundred and forty-seven patients were enrolled in this study among which 85 were patients with sarcoma. Stomatitis was the most common DLT observed. The dosing regimen, 40 mg QD × 5 days/week, provided the best combination of cumulative dose, dose density, and cumulative exposure, and was the recommended dosing regimen for subsequent clinical development. PK was nonlinear, with less than proportional increases in day-1 blood AUC0-∞ and Cmax, particularly with doses >40 mg. The terminal half-life estimate of ridaforolimus (QD × 5 40 mg) was 42.0 h, and the mean half-life ∼30-60 h. The clinical benefit rate, (complete response, partial response, or stable disease for ≥4 months was 24.5% for all patients and 27.1% for patients with sarcoma. CONCLUSION Oral ridaforolimus had an acceptable safety profile and exhibited antitumor activity in patients with sarcoma and other malignancies. ClinicalTrials.gov Identifier NCT00112372.

Abstract
A total of 360 patients with perennial allergic rhinitis were randomized in a placebo-controlled, dose-finding study comparing three concentrations (0.06%, 0.125%, and 0.25%) of a cetirizine nasal spray, administered three times a day for 2 weeks. The primary criterion of efficacy was the percentage of days with no or only mild symptoms of rhinitis (PDMax1), as evaluated by the patients. The median PDMax1 were 16.7%, 30.8%, 42.9%, and 26.7% for the placebo, 0.06%, 0.125%, and 0.25% groups, respectively. Although the global comparison among the four groups only approached statistical significance (P = 0.076), the difference (26.2%) between the placebo and 0.125% groups was clinically and statistically significant (P = 0.011). For the global evaluation by the investigator, the best results were seen in the 0.125% group (P = 0.03). The occurrence of adverse events did not differ among the four treatment groups and consisted mainly of nasal events, occurring in 22.5%, 17.1%, 12.9%, and 24.4% of the patients for the placebo, 0.06%, 0.125%, and 0.25% groups, respectively (P = 0.184). These results indicate that the 0.125% concentration is significantly better than placebo and offers the best therapeutic ratio.

Abstract
BACKGROUND The observed activity of cisplatin in breast cancer and its unattractive toxicity profile in palliative treatment warranted further study of platinum analogues in this disease. PATIENTS AND METHODS Sixty-two patients with recurrent or metastatic breast cancer, 61 of whom had been previously treated with chemotherapy, were randomly assigned to therapy with either iproplatin (n = 32) or carboplatin (n = 30). Both platinum analogues were administered intravenously, iproplatin at a dose of 240 mg/m2 every 4 weeks and carboplatin at a dose of 450 mg/m2 every 5 weeks. RESULTS Only two patients responded to iproplatin (7%) for durations of 21 and 61 weeks, and one patient responded to carboplatin (3%) for a duration of 64 weeks. All responses were complete. At the given dose schedules carboplatin was more myelosuppressive than iproplatin. Non-hematologic toxicities included nausea and vomiting (93% vs. 90%), diarrhea (20% vs. 10%) and hemorrhage (16% vs. 10%) for iproplatin and carboplatin, respectively. Two patients developed alopecia with carboplatin. No renal toxicity was observed. CONCLUSIONS Both iproplatin and carboplatin have limited activity in previously treated women with advanced breast cancer when given in conventional dosages.

Abstract
A 33-year-old woman, who at 29 underwent mastectomy for a localised breast cancer (TINOMO), presented a relapse shown by a rapid rise in seric level of CEA. The classical complete work-up was negative. The location of the relapse was demonstrated by anti-CEA immunoscintigraphy. Radiotherapy, hormonotherapy and chemotherapy allowed to achieve a complete remission with normalization of CEA level and of immunoscintigraphy.

Abstract
Brequinar sodium (DUP 785, NSC 368390) is a novel quinoline-carboxylic acid derivative that has been selected for clinical evaluation because of its broad spectrum of antitumor activity in animal models and its novel chemical structure. This compound inhibits the mitochondrial enzyme dihydroorotate dehydrogenase (DHO-DH), which catalyzes the conversion of dihydroorotate to orotate, leading to a blockage in the pyrimidine de novo biosynthesis. A total of 43 patients received 110 courses of Brequinar sodium by short-term intravenous (i.v.) infusion, which was repeated every 3 weeks. Dose escalation was initially based on a modified Fibonacci scheme. After pharmacokinetic data from mice and man became available, a pharmacologically guided dose escalation was used; at toxic levels, dose escalation was applied on the basis of clinical judgement. The dose-limiting toxicities were myelosuppression, mucositis, skin rash, nausea and vomiting. The maximum tolerable doses for poor- and good-risk patients were 1,500 and 2,250 mg/m2, respectively. One mixed response was observed in a patient with papillary carcinoma of the thyroid. The recommended doses for phase II studies are 1,200 and 1,800 mg/m2 Brequinar sodium, given by a 1-h i.v. infusion every 3 weeks to poor- and good-risk patients, respectively.

Abstract
A modified double-layer Hamburger and Salmon cloning assay was used to test cisplatin and its analogs (spiroplatin, carboplatin and iproplatin) on fresh tumor samples from 63 patients with a variety of non-hematological malignancies. Among them were 18 breast cancers, 17 ovarian cancers and 7 of unknown primaries. Half the patients received prior chemotherapy. Cisplatin regimens were given in 16 cases. When possible, cells were exposed for 1 h to each drug in concentrations of 0.1 microgram/ml and 1.0 microgram/ml for cisplatin and spiroplatin, 1.0 microgram/ml and 10 micrograms/ml for carboplatin and iproplatin. A greater than or equal to 50% cell kill with at least one drug was found in 20 samples including 8 ovarian cancers, 3 breast cancers and 1 unknown primary. A greater than or equal to 70% cell kill was seen in 2 samples with cisplatin, 3 with spiroplatin and carboplatin, and 6 with iproplatin. There was only partial cross-resistance between cisplatin and its analogs. Among 57 paired comparisons of cisplatin with spiroplatin, 2 showed drug sensitivity to cisplatin alone, 6 to spiroplatin alone, and 6 to both. The same sort of observation was made with carboplatin. The lack of cross-resistance between cisplatin and iproplatin was particularly striking: among 53 pairs, 6 were sensitive to cisplatin alone, 8 to iproplatin alone, and 2 to both. About 20% of the samples that were resistant to cisplatin were sensitive to iproplatin. Our data show hints of activity in breast and ovarian cancers with all analogs and suggest that they will achieve clinical antitumor activity similar to that they will achieve clinical antitumor activity similar to that of cisplatin. The in vitro evidence of incomplete cross-resistance between cisplatin and its analogs should be investigated further.

Abstract
Phase II trials of flavone acetic acid have been performed in a total of 87 patients including 17 with advanced breast cancer, 23 with advanced colorectal cancer, 25 with advanced malignant melanoma and 22 with advanced head and neck cancer. Patients with colorectal cancer and melanoma had received no prior chemotherapy; in breast and head and neck cancer patients prior chemotherapy had been given with a median of 5 and 2 drugs respectively. The schedule used was a once-weekly regime, with a dose of 4.8 gms/m2 given as a 1 hour infusion, together with alkalinization (with i.v. sodium bicarbonate) given before and after FAA. Reassessment was performed after 6 weekly doses, although in 23 patients fewer than 6 doses were given, because of early disease progression in 15, and undue toxicity in 5. An additional 3 patients died within 72 hours of having received FAA and, although the precise cause of death in each case was not established, FAA toxicity could not be excluded. Treatment was generally manageable, the major manifestations of toxicity comprising uncomfortable warmth and flushes, nausea, diarrhoea, and visual complaints. Hypotension was also documented in 8 patients. No objective responses were seen in any of the patient sub-groups, although disease-stabilization was seen in 3 patients with breast cancer, 1 patient with advanced colorectal cancer, 2 patients with advanced melanoma and 4 patients with head and neck cancer. Further Phase II studies, using a higher dose of 8.6 gm/m2 over 6 hours once weekly, are currently in progress in Europe.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
For chemosensitivity testing, a rapid in vitro colorimetric method (MTT assay) was used. Eleven head and neck cancer cell lines were investigated to distinguish five known active agents from five compounds inactive in phase II studies. Evaluation of the reliability of the assay for assessing drug sensitivity in this tumor cell population was done by correlating the in vitro results with reported in vivo response data. Methotrexate and cisplatin (clinically active) and vindesine and doxorubicin (less active clinically) were recognized in vitro as active and correlated well with clinical experience. Bleomycin (clinically active) was ineffective against some cell lines. The in vitro findings for the clinically inactive drugs (deoxyazacytidine, lomustine, and carmustine) also corresponded. Amsacrine and etoposide, contrary to clinical experience, showed activity in vitro. Further comparison of MTT assay results with clinical data is warranted and essential before its use in large-scale drug screening studies.

Abstract
The pharmacokinetics of the novel antipyrimidine agent Brequinar sodium (NSC 368390; DUP 785) was studied in 23 patients with solid tumors during the phase I study of this compound. The drug was administered by short-term (10-60 min) intravenous infusion every 3 weeks. The doses ranged from 15 to 2250 mg/m2. At doses higher than 1500 mg/m2 the areas under the plasma concentration vs. time curve (AUC) increased non-proportionally, while the total body clearance (Clt) dropped substantially, indicating non-linear pharmacokinetics of the drug. Brequinar sodium showed a triphasic decay of plasma concentrations with half-life ranges of 11.1-36.6 min, 1.7-6.9 h and 12.5-25.0 h, respectively. The volume of distribution (Vdss) ranged from 4.4 to 10.6 l/m2. The total body clearance (Clt) ranged from 6.9 to 22.1 ml/min with a small contribution of the renal clearance (0.04-0.4 ml/min). Up to 7 days, the cumulative urinary excretion (CUE) and the cumulative fecal excretion (CFE) ranged from 0.4 to 8.3% and from 7.7 to 18.3% of the dose, respectively. There was evidence for the presence of drug metabolites in urine and feces. There was no drug accumulation with repeated administration of Brequinar sodium by the above mentioned drug schedule. The ratio between the plasma AUC at the maximum tolerable dose (MTD) in man and that at the mouse LD10 was 0.8, while the ratio between the respective doses was 5.7. The ratios between the AUC in patients and that at the mouse LD10 were applied to guide dose escalation in the phase I study. The results of the above mentioned pharmacokinetic studies were useful for the choice of an optimal schedule for phase II trials of Brequinar sodium.

Abstract
Carbetimer is a new antineoplastic agent whose limiting toxicity consists of dose- and treatment duration-dependent hypercalcemia. We examined the short-term effects of Carbetimer on calcium metabolism on days, 1, 3 and 5 during 11 5-day courses (6.5-8.2 g/m2/day given over daily 2-h infusions, q 3-4 weeks). Blood parameters were measured before and after Carbetimer, whereas urinary parameters were studied in three consecutive 2-h collections before, during and after Carbetimer infusions. Carbetimer effects were similar regardless of the infusion day. We found a consistent decrease of plasma ionized Ca (Ca2+) levels from 4.56 +/- 0.05 mg/dl before infusion to 4.28 +/- 0.06 mg/dl after infusion (P less than 0.001) whereas total serum Ca (corrected for protein levels) did not change. The fall of Ca2+ stimulated parathyroid function, as suggested by the increased plasma PTH levels, the decreased serum phosphorus and TmP/GFR index, or the increased urinary phosphate and cyclic AMP excretion. Carbetimer infusions also induced a marked increase in urinary Ca excretion (expressed as mg Ca/mg creatinine) from 0.093 +/- 0.011 before to 0.359 +/- 0.042 during and 0.177 +/- 0.031 after infusion (P less than 0.011). These changes were best explained by Carbetimer-induced Ca chelation that we confirmed in vitro by incubating Carbetimer at various concentrations in whole blood for 2 h at 37 degrees C, e.g. 2 mg of Carbetimer/ml lowered Ca2+ from 4.82 to 3.20 mg/dl without changing total Ca levels. On the other hand, a direct effect of Carbetimer on bone cannot be excluded since we observed an increase of serum osteocalcin levels from 2.0 +/- 0.3 to 2.5 +/- 0.4 ng/ml after infusion (P less than 0.001). In summary, the short-term effects of Carbetimer on calcium metabolism markedly differ from the long-term effects. They mainly consist of a dose-related calcium chelation leading to a decrease in Ca2+ levels, an increase in urinary Ca excretion and a stimulation of parathyroid function.

Abstract
The liver is a frequent site of metastases and in several cases the only available target for assessing the activity of chemotherapeutic agents. A standard procedure for liver measurements by ultrasound was investigated. One hundred and twenty-three chemotherapy cycles were evaluated. This study shows that metastatic involvement of the liver can be measured by several ultrasound parameters which represent different features of the same process: the number and the surface of the nodules, the volume of the organ. Ultrasound parameters were correlated with liver function tests, CEA, hepatomegaly and measurements of other metastatic sites. The surface of metastases still appeared to be the most reliable criterion of response. Our results suggest that several liver ultrasound parameters may help to definitely assess the type of response to chemotherapy.

Abstract
Carbetimer, a low molecular weight polymer derived from ethylene and maleic anhydride, belongs to a class of chemical compounds different from previously available anticancer agents. It has shown moderate antitumor activity against the Madison 109, Lewis lung, colon 26 and M5076 ovarian carcinomas. In the human tumor stem cell assay, antitumor activity was seen against carcinomas of the breast, ovary, lung, colon and kidney. A total of 26 patients with solid tumors were entered into this trial; carbetimer was given on 5 consecutive days as a 1-2-h intravenous infusion. The dose was escalated from 1.08 to 11 g/m2/day. The drug did not induce the usual side-effects of chemotherapy: leukopenia, thrombocytopenia, alopecia and mucositis were minimal or totally absent. Gastrointestinal toxicity was limited to mild to moderate nausea and vomiting; these were observed at all dose levels and required antimetics in only two patients. The major side-effects of carbetimer consisted of hypercalcemia and neurotoxicity. Hypercalcemia was dose- and treatment duration-dependent. The precise mechanism of hypercalcemia is presently under investigation, but remains unclear. Neurotoxicity was observed only after prolonged therapy; two patients, who received cumulative doses higher than 250 g/m2, developed a peripheral neuropathy with paresthesia, decrease in sensory perception and motor weakness. One patient recovered completely; the other patient improved slightly before developing fatal brain metastases. Two patients with malignant melanoma exhibited major antitumor response; both were previously treated; after excellent partial responses to carbetimer, both were operated on and one is presently disease-free 2 1/2 years after completion of therapy with carbetimer. In conclusion, carbetimer is a new compound with an unusual pattern of side-effects and interesting antitumor activity against malignant melanoma. Its antitumor activity is presently being investigated in phase II trials.

Abstract
Brequinar sodium (NSC 368390; DUP 785) is a new inhibitor of pyrimidine de novo biosynthesis which has completed Phase I clinical trials within the framework of the Early Clinical Trials Group of the European Organization for Research and Treatment of Cancer (EORTC). The main side effects of this compound are myelosuppression, nausea and vomiting, stomatitis and/or mucositis, and skin rash. In this report, the authors describe the pattern of mucocutaneous side effects of Brequinar sodium in patients who received the drug by four different schedules: (1) short-term intravenous (IV) infusion every 3 weeks; (2) weekly; (3) twice weekly; and (4) five times daily every 4 weeks. Mucocutaneous toxicities of Brequinar sodium included mainly cytotoxic reactions (stomatitis and/or mucositis and skin rash). However, rare episodes of local reactions (phlebitis at the site of injection), photosensitivity reactions (to sun light), angioneurotic edema, and localized secondary hyperpigmentation of the inflamed skin also occurred. Stomatitis and/or mucositis appeared to be dose-dependent and schedule-dependent. The skin rash consisted of a drug-induced toxic dermatitis which occurred mostly at the highest dose levels. Initial recommendations for the management of mucocutaneous toxicities of Brequinar sodium during Phase II trials are discussed.

Abstract
The relative toxicities of cisplatin and its analogs, spiroplatin, carboplatin, iproplatin and JM40, were tested against normal human progenitor myeloid cells (CFU-GM) in a clonogenic assay. Cells obtained from five bone marrows were incubated for 60 min with various drug concentrations and plated. The mean inhibitory concentrations for 50% of the bone marrow colonies (IC50) were 15.6 micrograms/ml for cisplatin, 0.4 micrograms/ml for spiroplatin, 56.3 micrograms/ml for carboplatin, 36.3 micrograms/ml for iproplatin and 179.5 micrograms/ml for JM40. Ratios of the IC50s of the analogs with cisplatin as reference drug closely followed the corresponding ratios of the clinical maximum tolerated doses. This correlation between the CFU-GM assay results and the clinical myelotoxicity suggests that the assay is adequate for predicting myelotoxicity in vitro and selecting in vitro drug concentrations for the human tumor clonogenic assay.

Abstract
The human tumor stem-cell assay was used to investigate the in vitro chemosensitivity of 27 evaluable samples to cisplatin and its analogues, iproplatin and carboplatin, as well as to BCNU, teniposide, vindesine, and dibromodulcitol. All agents exhibited some antitumor activity with the exception of dibromodulcitol (zero response out of 19 evaluable samples). Vindesine, BCNU, and carboplatin were the three most active compounds, with response rates of 29%, 23%, and 22%, respectively. There was a lack of complete cross-resistance between carboplatin and cisplatin as well as between carboplatin and BCNU. Our data suggest that clinical studies with carboplatin and combinations of vindesine plus cisplatin and its analogues may be worthwhile.

Abstract
Eighteen adult patients with solid tumors were treated with oral menogaril, a new anthracycline antibiotic active against human breast cancer after intravenous administration. The drug was given orally on 3 consecutive days every 4 weeks at doses ranging from 50 to 175 mg/m2/day. Reversible and dose-related leukopenia was the dose-limiting toxicity. Thrombocytopenia was less frequent. Hematologic toxicity was maximal usually 2 weeks after treatment and recovery usually occurred within 4 weeks. At doses from 50 to 150 mg/m2/day, non-hematologic side-effects of oral menogaril were infrequent and mild and consisted of nausea and vomiting (one patient), alopecia (two patients), mucositis (two patients) and liver function test abnormalities (three patients). The single patient treated at a daily dose of 175 mg/m2/day developed grade IV leucothrombocytopenia, with fever and gastrointestinal bleeding. This was followed by heart failure and the patient died from multisystem organ failure. Peak plasma concentrations of menogaril ranged from 0.043 to 0.409 microM and were linearly correlated with the dose. Similarly, the area under the plasma concentration versus time curve varied from 0.33 to 9.59 microM X h and was linearly correlated with the dose. The mean harmonic half-life was 11.3 +/- 6.4 h. A comparison of the data from the present trial and our previous study with intravenous menogaril indicates a bioavailability of 32 +/- 12%. There was an excellent relationship between the white blood cell decrease (as a percentage of the pretreatment value) and several pharmacokinetic parameters; the best correlation was obtained with the plasma concentration of menogaril at 4 h after treatment. A dose of 150 mg/m2/day for 3 consecutive days is recommended for phase II trials with oral menogaril but the bioavailability of the drug should be monitored carefully and, more specifically, the concept of a pharmacokinetic adjustment of the dose of menogaril should be evaluated prospectively.

At doses from 50 to 150 mg/m2/day, non-hematologic side effects of oral menogaril were unfrequent and mild and consisted of nausea and vomiting (1 patient), alopecia (2 patients), mucositis (2 patients) and liver function test abnormalities (3 patients). The only patient treated at a daily dose of 175 mg/m2 developed grade IV leukothrombocytopenia, with fever and gastrointestinal bleeding. This was followed by heart insufficiency and the patient died from multisystem organ failure. A dose of 150 mg/m2/day for 3 consecutive days is recommended for phase II trials with oral menogaril.

Abstract
Many in vitro investigations with anticancer agents are performed at concentrations equal to the peak concentrations or fractions of the peak concentrations achieved in human plasma after administration of these agents. In an effort to develop an in vitro test capable of predicting these peak plasma concentrations prior to the completion of pharmacokinetic studies, the effect of several classes of anticancer agents against normal human bone marrow myeloid progenitor cells (CFU-GM) was studied. The investigated agents included anthracycline antibiotics, cisplatin and its analogs, anthracene derivatives and two flavone acetic acid derivatives. The CFU-GM were exposed to these agents for 30-60 min. An exponential relationship between drug concentration and CFU-GM growth was observed for all compounds with the exception of the flavone acetic acid derivatives which were inactive. For the latter two compounds, an inhibition of CFU-GM growth was observed after continuous exposure. When compared to the plasma concentrations after parenteral administration of these agents, there was a very good agreement between 1/10 of the peak plasma concentration and the concentration inducing a 90% inhibition of the CFU-GM growth for the anthracycline antibiotics and anthracene derivatives. In contrast, for cisplatin and its analogs, there was a better agreement between 1/10 of the peak plasma concentration and the concentration inducing a 10% inhibition of CFU-GM growth. The combination of concentrations inducing inhibitions of 10 and 90% of the CFU-GM growth provides a range of concentrations that predict reasonably well the peak plasma concentrations of several anticancer agents and that could be used as guides for other in vitro investigations.

Abstract
The in vitro evaluation of new antineoplastic agents has been advocated as a method of selecting drugs for Phase I-II trials in patients. This paper is an attempt to validate, in an unbiased manner, the so-called in vitro Phase II clonogenic assay with regard to its predictive power in the clinic. Breast and ovarian cancer were chosen because of the relatively large number of drugs clinically evaluated for these diseases; 298 patients were studied. For metastatic breast cancer 12 drugs, six clinically active and six inactive, were tested. It was found that in patients without prior chemotherapy, there is an association between results in vitro and in vivo. In metastatic ovarian cancer, 11 drugs, four of which are known to be clinically inactive, were studied. The same positive association was seen for patients without prior chemotherapy. The implications of these findings are discussed.

Abstract
The cytotoxic effect of daunorubicin, carminomycin, idarubicin and the major metabolite of idarubicin in man, 4-demethoxydaunorubicinol, was investigated in a human normal progenitor myeloid stem cell assay and in a human tumor stem cell assay. Against normal myeloid progenitor cells, idarubicin and carminomycin were equally potent; both agents were significantly (P less than or equal to 0.01) more potent than daunorubicin. Idarubicin was approx. 2.5 times more potent than 4-demethoxydaunorubicinol. Against malignant tumor cells, 50% cell kill after exposure to idarubicin was observed in four out 24 samples; this inhibition occurred at a drug concentration of 0.1 micrograms/ml. Two of the samples sensitive to idarubicin were also sensitive to 4-demethoxydaunorubicinol at a concentration of 0.1 micrograms/ml. Overall, idarubicin was active against two out of six ovarian carcinomas and against one out of three breast carcinomas. Our data confirm that 4-demethoxydaunorubicinol may play a role in the biological activity of idarubicin.

Abstract
The Early Clinical Trials Cooperative Group of the EORTC conducted several phase II studies with a pyrimidine analogue of deoxycytidine, 5-aza-2'-deoxycytidine (DAC). The drug was given as three consecutive 1 h i.v. infusions of 75 mg/m2, separated by intervals of 7 h; courses were repeated every 5 weeks. A total of 101 eligible patients were studied: 42 with colo-rectal adenocarcinoma, 27 with squamous cell carcinoma of the head and neck, 18 with malignant melanoma and 14 with renal cell carcinoma. Drug-induced toxicities consisted of moderate myelosuppression, and nausea and vomiting. One single partial remission was seen in a patient with malignant melanoma. DAC given in this dose and schedule is devoid of antitumour activity in adult patients with these refractory types of carcinomas.

Abstract
A total of 185 eligible patients with advanced inoperable squamous cell carcinoma of the head and neck were randomized into two groups; the cisplatin, methotrexate, bleomycin, and vincristine (CABO) group received cisplatin (50 mg/m2; day 4), methotrexate (40 mg/m2; days 1, 15), bleomycin (10 mg; days 1, 8, and 15), and vincristine (2 mg; days 1, 8, and 15) and the ABO group received methotrexate, bleomycin and vincristine in the same doses on days 1, 8, and 15. After three courses, patients in both arms received weekly methotrexate as maintenance therapy; those 34 patients with previously untreated locoregional disease went off the study because of subsequent locoregional treatment in form of radiotherapy +/- surgery. The complete response rate was 16% in patients receiving CABO, compared with 5% among patients given ABO. The corresponding overall response rates were 50% and 28%, respectively (P = 0.003). Among patients with recurrent or metastatic disease, progression was delayed in patients receiving CABO (median, 18 weeks) compared to those receiving ABO (median, 14 weeks) (P = 0.07), but there was no difference in survival time. Myelosuppression consisted mostly of leukopenia, which was seen in 67% of the CABO patients versus 47% in the other arm. Myelosuppression-associated infection and hemorrhage led to death in two patients in the CABO treatment group and six patients in the ABO treatment group. Nausea and vomiting, mostly of grades 1 or 2, occurred in 93% of the patients given CABO and 44% of those receiving ABO. Other toxic effects--neuropathy, alopecia, stomatitis, constipation, fever/chills, diarrhea, cutaneous alterations, and renal impairment--occurred equally in the two treatment groups. This study underlines the role of cisplatin in head and neck cancer, although no impact on survival could be demonstrated. It also supports indirectly the superiority of combination chemotherapy over single-agent treatment for this disease.

Abstract
Sixteen patients with advanced ovarian carcinoma were treated with anaxirone (1,2,4-triglycidylurazol, TGU), 600 mg/m2 every 4 weeks. Anaxirone was the second or later line of therapy. All patients had evaluable tumors and evidence of failure of prior therapy. None of the patients responded. Two had stabilization of the disease for 4 months. In one patient WHO grade 4 leukopenia and grade 4 thrombocytopenia were observed after the second TGU cycle starting on day 41 and persisted until the patient died due to tumor progression (day 50). No patient experienced thrombophlebitis.

Abstract
Rat liver cytosol and buttermilk xanthine oxidase both converted 7-deoxypyrromycinone, the 7-deoxyaglycone of marcellomycin, a new anthracycline antibiotic, to a nonfluorescent compound under anaerobic conditions and in the presence of an electron donor. Reduced nicotinamide adenine dinucleotide and reduced nicotinamide adenine dinucleotide phosphate were equally effective electron donors for liver cytosol, and xanthine was the best cofactor for xanthine oxidase. However, xanthine was inactive with liver cytosol. Reactions with xanthine oxidase obeyed Menten-Michaelis kinetics and were inhibited by allopurinol. No xanthine oxidase activity was detected in liver cytosol. Xanthine oxidase also induced a loss of fluorescence when incubated with 7-deoxydaunorubicin aglycone. The nonfluorescent metabolite of 7-deoxypyrromycinone was tentatively identified as the dihydroquinonic derivative of the parent deoxyaglycone on the basis of its spectrophotometric, fluorescent, thin layer chromatographic, and mass spectral characteristics. Our data demonstrate that more than one enzymatic activity, xanthine oxidase, and an unidentified rat liver cytosolic enzyme convert the 7-deoxyaglycones of anthracycline antibiotics to nonfluorescent metabolites.

Abstract
Teicoplanin (0.2 g) or vancomycin (1 g) were infused over 3 and 50 min respectively to six male volunteers in a cross-over study. Each drug was administered twice at a 14 h interval. The pharmacokinetics of both drugs were accurately described using a two-compartment model. Vancomycin had a shorter half-life (5.8 +/- 1.8 h) compared to teicoplainin (33.2 +/- 5.1 h; P less than 0.001). One hour serum was tested for serum bactericidal activity against ten strains each of Staphylococcus aureus (median serum bactericidal activity 1:16 for teicoplanin; 1:32 for vancomycin), Staph. epidermidis (1:32 for teicoplanin and for vancomycin) and Streptococcus faecalis (1:2 for both drugs). Serum killing rate studies showed a slower rate of killing of Staph. aureus with teicoplanin (less than 1 log10 cfu/ml over 6 h) than with vancomycin (4 log10 cfu/ml over 6 h).

Abstract
The in vitro metabolism of marcellomycin by rat tissue fractions showed conversion of marcellomycin to 7-deoxypyrromycinone, bisanhydropyrromycinone, and an as yet unidentified compound by rat liver homogenate, microsomes, cytosol, and mitochondria, and purified hepatic reduced nicotinamide adenine dinucleotide phosphate-cytochrome P-450 reductase, under anaerobic conditions and in the presence of reduced nicotinamide adenine dinucleotide phosphate. All these fractions except the purified reductase subsequently induced a progressive loss of fluorescence. Mitochondria, however, were much less active than microsomes, cytosol, and homogenate in inducing this latter phenomenon. Marcellomycin was converted to 7-deoxyaglycones only partially by nuclei. No loss of fluorescence was observed with this subcellular fraction. No loss of fluorescence was observed when doxorubicin or daunorubicin were incubated under similar conditions. The appearance of a compound with distinct spectrophotometric properties was demonstrated by absorbance spectrometry. The formation of a compound with different fluorescent characteristics was excluded, as was the binding of the aglycones to subcellular components. The activity inducing the loss of fluorescence was studied in greater detail with cytosol. It predominated in the liver and required both an electron donor and anaerobic conditions. The optimal pH for the reaction was between 7.5 and 8.0. Our results suggest the existence of an enzymatic pathway capable of converting the fluorescent nucleus of marcellomycin to a nonfluorescent metabolite.

Abstract
Fourteen patients with metastatic renal adenocarcinoma without prior chemotherapy were treated with 1,2,4-triglycidylurazol (TGU, NSC-332488), a new triepoxide alkylating agent. TGU was chosen for this study among other triepoxides because of its high antitumour activity in animal models, its relatively good water solubility and the expected favourable therapeutic index. The starting dose was 800 mg/m2 i.v. (600 mg/m2 for patients with prior extensive radiotherapy) every 4 weeks. No objective tumour regression was seen in this favourable group of patients. Leuko- and thrombocytopenia were the most important side-effects. Severe cumulative and prolonged thrombocytopenia was seen. Other toxicities observed were nausea with or without vomiting in all patients and local phlebitis in some.

Abstract
Triglycidylurazol is a teroxirone derivative proposed for clinical trials on the basis of a broad spectrum of activity against murine tumors and a reduced potential for toxic manifestations at the injection site as compared to the parent compound. This phase I trial was designed to define the maximum tolerated dose of triglycidylurazol given by iv bolus on a 5-day schedule. Twenty-eight adult patients with a variety of solid tumors were entered. Their median performance status was 2 (range, 0-3), and most had received prior radiotherapy, chemotherapy, or both. A median of one course (range, one to four) was administered, for a total of 47 courses. Doses were escalated from 6 to 250 mg/m2/day. Leukopenia and thrombocytopenia were dose-related and -limiting, with a strong suggestion of increased myelosuppression with repeated courses. Nonhematologic toxic effects were generally mild to moderate. Nausea and vomiting were experienced by most patients. Local toxic effects consisting of venous discoloration, phlebitis, and/or sloughing were encountered in about one-half of the patients. Possible drug-related impairments in liver function were noted in three patients. Negligible alopecia and fatigue were also observed. Antitumor effect was detected in one patient with adenocarcinoma of unknown origin. A dose of 200 mg/m2/day for 5 consecutive days may be recommended for phase II trials.

Abstract
The effect of hyperthermia on the uptake and metabolism of doxorubicin (ADM) was studied in in vitro systems. ADM uptake in rat liver slices was not affected by increasing the temperature from 37 degrees C to 43 degrees C. In rat liver homogenates, the aerobic transformation of ADM was low and was not affected by hyperthermia. Approximately 90% of the parent drug remained unchanged after 60 minutes of incubation, and two metabolites, adriamycinol and a polar metabolite, were formed in small amounts. Under anaerobic conditions, ADM was quickly and extensively converted to two metabolites identified as 7-deoxyadriamycinol aglycone and 7-deoxyadriamycin aglycone. Whereas the disappearance of ADM and the formation of 7-deoxyadriamycin aglycone were not modified by the hyperthermic conditions, there was a slight but significant increase of the formation of 7-deoxyadriamycinol alycone (area under the concentration versus time curve in microM X minute: 216 +/- 24 at 37 degrees C; 235 +/- 24 at 39.5 degrees C; and 271 +/- 8 at 42 degrees C; P less than or equal to 0.05). However, the percentage of dA3 was not significantly different at the end of the incubation.

Abstract
Thirty-three adult patients with solid tumors were treated with menogaril, a new anthracycline antibiotic. The drug was given as a two-hour infusion every 4 to 5 weeks at doses ranging from 17 to 250 mg/m2. The maximum tolerated dose was 250 mg/m2. Reversible and dose-related leukopenia was the dose-limiting toxicity. Thrombocytopenia was less frequent. Hematologic toxicity was maximal 2 weeks after treatment, and recovery usually occurred within 4 weeks. There was no dissociation between WBC and neutrophil counts, and myelosuppression did not appear to be cumulative up to 200 mg/m2. Myelosuppression was more severe for patients with heavy pretreatment and/or bone marrow involvement. Local toxicity consisting of phlebitis and/or erythema was the most common nonhematologic toxicity, especially at 250 mg/m2 (eight out of nine patients). Usually, erythema appeared within 24 hours after treatment at or near the infusion site and resolved within a few days. Occasionally, a more persistent (several weeks) orange discoloration suggesting cutaneous deposits of menogaril was observed. Nausea and vomiting were uncommon and never severe. Alopecia and mucositis were rare. Minor arrhythmias were seen in several patients during treatment, but their relationship with menogaril therapy was unclear, and in no patient did heart failure develop. Plasma concentrations were best described by a tricompartmental model with a mean terminal half-life of 29.5 hours and a mean total-body clearance of 20.2 L/h/m2. Doses of 160 and 200 mg/m2 are recommended for phase II trials in poor- and good-risk patients, respectively.

Abstract
Under anaerobic conditions, in comparison to liver microsomes obtained from normal controls, liver microsomes obtained from rats pretreated with cyclophosphamide formed significantly less 7-deoxydoxorubicinol aglycone (P less than or equal to .05), whereas the disappearance of doxorubicin and the formation of 7-deoxydoxorubicin aglycone were unaffected. When directly investigated, the reduction of 7-deoxydoxorubicin aglycone to 7-deoxydoxorubicinol aglycone by microsomes was inhibited by cyclophosphamide pretreatment. Liver cytosols from controls and cyclophosphamide-treated rats reduced daunorubicin to daunorubicinol and 7-deoxydoxorubicin aglycone to 7-deoxydoxorubicinol aglycone at the same rate, which indicates the lack of effect of cyclophosphamide pretreatment on the cytosolic aldoketoreductase. The results suggest the existence of a microsomal carbonyl reduction system for anthracycline antibiotics and indicate that cyclophosphamide does affect the metabolism of doxorubicin; in rats, this interaction results only in an alteration of the relative concentrations of presumably inactive metabolites, the 7-deoxyaglycones. The importance of these findings for the pharmacological interaction between doxorubicin and cyclophosphamide in humans remains to be investigated.

Abstract
Thirty-six evaluable patients with locoregionally recurrent or metastatic squamous cell carcinoma of the head and neck were treated with a combination of mitomycin (10 mg/m2 i.v. day 1), fluorouracil (500 mg/m2 i.v. days 1 + 8) and hydroxyurea (1 g/m2 orally days 2-14). Thirty-three patients had received prior radiation therapy and 34 prior chemotherapy. Only two patients exhibited a partial response. Hematological toxicity was substantial, with three patients experiencing leukopenia below 1000/mm3 and seven patients experiencing thrombocytopenia below 25,000/mm3. There were four cases of treatment-related bleeding and one infection. Other side-effects were mild to moderate. Low antitumor activity and substantial toxicity preclude further evaluation of this regimen in head and neck cancer.

Abstract
The activity of menogaril and its major metabolite in animals and humans, N-demethylmenogaril, has been investigated in the human stem cell assay as developed by Salmon et al. Among 31 evaluable samples, four were sensitive to menogaril, including one which responded to N-demethylmenogaril. Three samples resistant to menogaril responded to N-demethylmenogaril. None was sensitive to doxorubicin. Overall, one out of seven ovarian samples and one out of three breast samples responded to menogaril. Our data confirm the in vitro activity of menogaril in ovarian and breast cancer; in addition, they suggest incomplete cross-resistance between doxorubicin and menogaril and, considering the concentrations of N-demethylmenogaril in animals and humans, a minor role for this metabolite in the overall antitumor activity of the parent compound.

Abstract
The effect of 3 anthracene derivatives, mitoxantrone, ametantrone, bisantrene, on 4 normal human bone marrows, was studied using the myeloid stem cell assay developed by Pike and Robinson, in order to define to what extent this test could be used to predict the relative clinical hematologic toxicity of new anticancer agents. For the 3 drugs, an exponential relationship between colony survival and drug concentration was found, but was much steeper for mitoxantrone (slope = -195.2 +/- 8.8/micrograms/ml) than for ametantrone (slope = 5.1 +/- 1.0/micrograms/ml, p less than or equal to 0.001) and bisantrene (slope = 7.1 +/- 0.3/micrograms/ml, p less than or equal to 0.001). The difference of slope between ametantrone and bisantrene was of borderline significance (p less than or equal to 0.05). The ratios of concentrations inducing a 50% growth inhibition for mitoxantrone versus bisantrene and for ametantrone versus bisantrene were close to the corresponding ratios of concentrations inducing a 90% growth inhibition. The relative in vitro toxicities reproduce very well the relative myelosuppression observed in clinical trials with mitoxantrone versus bisantrene but the results were less satisfactory for the comparison of these 2 agents with ametantrone. In addition, our data suggest that, for these 3 compounds, intrinsic myeloid progenitor sensitivity is a major determinant of leukopenia.

Abstract
Thirty one patients with solid tumors were entered into a phase I trial with idarubicin, a new anthracycline antibiotic with oral antitumor activity in animals. The drug was scheduled to be given for 4 consecutive weeks at doses ranging from 10 to 20 mg/m2. Leukopenia was the dose-limiting toxicity. Thrombocytopenia was occasionally seen. Since several patients could not receive the third and fourth administrations of the drug at 17.5 and 20 mg/m2, higher doses were administered only for 2 consecutive weeks. With this schedule, the maximum tolerated dose was 25 mg/m2 and leukopenia was again the dose-limiting toxicity. With both schedules, myelosuppression was highly variable and could not be related to prior therapy, bone or liver metastases, or performance status. Other toxicities were mild to moderate and were dominated by nausea and vomiting which were observed in 29% of the patients. Alopecia and mucositis were unfrequent and cardiac toxicity was not observed. Starting doses of 15 mg/m2 for 4 consecutive weeks or 20 mg/m2 for 2 consecutive weeks could be proposed for oral phase II studies with idarubicin, under careful pharmacokinetic monitoring.

Abstract
Plasma and milk concentrations of doxorubicin (DOX) and cisplatin were measured after iv administration of these agents to a lactating patient with ovarian cancer. Cisplatin was undetectable in human milk. Milk concentrations of DOX often exceeded those detected in concomitant plasma samples. For DOX, the highest milk:plasma concentration ratio was 4.43:1 and was observed 24 hours after administration of the drug. The area under concentration versus time curve (AUC) for DOX was approximately the same in plasma and milk. Doxorubicinol was the major metabolite of DOX in plasma and in milk. The AUC for doxorubicinol was ten times higher in milk than in plasma. However, the total amount of anthracycline antibiotic delivered in the milk (maximum concentration of active anthracycline antibiotic: 0.24 mg/L) was negligible.

Abstract
We have investigated the metabolism and disposition, in rabbits, of menogaril (7-OMEN), a new anthracycline antibiotic recently introduced into clinical trials. 7-OMEN was administered by rapid i.v. injection at a dosage of 2.5 mg/kg. 7-OMEN and metabolites were assayed by high performance liquid chromatography. Plasma concentrations of 7-OMEN declined in biexponential fashion with a terminal half-life of 2.7 h. The area under the plasma concentration versus time curve was 1.3 microM X h. The systemic clearance of 7-OMEN was 57.6 ml/min/kg. No metabolite of 7-OMEN was detected in plasma. At 8 h after treatment, the cumulative urinary and biliary excretions of 7-OMEN equivalents amounted to 1.3 and 3.4% of the total administered dose, respectively. 7-OMEN was the predominant fluorescent compound in urine, but four metabolites were also seen. In bile, 7-OMEN represented only 9.6% of the cumulative excretion and six metabolites were observed. Among the organs, lungs contained the highest concentrations of parent drug. Substantial concentrations of metabolites were observed in the kidneys, liver, duodenum, and small intestine. Three of the observed metabolites of 7-OMEN have been tentatively identified as N-demethylmenogaril, 7-deoxynogarol, and N-demethyl-7-deoxynogarol.

Abstract
The metabolism and tissue distribution of aclacinomycin A (ACL), marcellomycin (MCM), and musettamycin (MST), three new anthracycline antibiotics, were compared after IV administration to mice. In plasma, total MCM- and ACL-derived fluorescence declined according to first-order kinetics, whereas an initial decline followed by a rebound was observed for MST. In plasma, MCM remained the predominant compound. ACL was eliminated more quickly, and was replaced by two metabolites, the reduced glycoside M1, and an aglycone. In the case of MST, two unidentified metabolites were observed in concentrations equivalent to that of the parent drug. The three drugs were distributed widely to organs, but only ACL achieved measurable concentrations in the brain. Initially, high concentrations of all three drugs were present in the lungs, but these decreased quickly to values similar to those present in the liver and kidneys. Intermediate concentrations of the three drugs were measured in heart and skeletal muscle. Splenic concentrations of all three drugs rose progressively, reaching a maximum at 8 h after injection in the case of ACL and MST, and at 24 h after injection in the case of MCM. Concentrations of the metabolites of MCM and MST were low in all organs except liver and kidney, where the aglycones 7-deoxypyrromycinone and bisanhydropyrromycinone were seen. The metabolism of ACL was extensive. Aglycones were dominant in the liver and kidneys, whereas reduced glycosides predominated in the spleen. These observations indicate that the murine pharmacology of these three structurally similar drugs differs markedly.

Abstract
The pharmacokinetics of esorubicin, a new anthracycline antibiotic, was investigated in conjunction with a phase I clinical trial. The drug was administered to 12 patients as an intravenous bolus at a dose of 20 to 40 mg/m2. All patients had normal renal and hepatic functions and no third space fluid accumulation. Plasma and urine samples were assayed by HPLC. The peak plasma concentration of esorubicin was 0.74 +/- 0.57 microM (mean +/- SE). Esorubicin disappeared from plasma according to a tri-exponential pattern with a terminal half-life of 20.4 +/- 7.3 hr. The area under the plasma concentration versus time curve was 0.64 +/- 0.31 microM x hr. Total body plasma clearance was 45.5 +/- 26.8 liter/min/m2 and the apparent volume of the central compartment, 41.0 +/- 24.8 L. A single metabolite, 4'-deoxydoxorubicinol, was detected in plasma. This metabolite was observed in 5 patients only and its mean peak concentration was 0.029 +/- 0.017 microM. The area under the plasma versus concentration time curve for 4'-deoxydoxorubicinol was 0.02 +/- 0.014 microM xhr. The urinary excretion of total fluorescence within 5 days of therapy was 7.3 +/- 1.3% of the administered dose. Esorubicin represented more than 80% of the excreted anthracyclines. As in plasma, 4'-deoxydoxorubicinol was the only metabolite detectable in urine. No correlation between the various pharmacokinetic parameters and drug-induced toxicity was observed in this small group of patients.

Abstract
In conjunction with two phase I clinical trials, we have investigated the pharmacokinetics of marcellomycin (MCM), a new class II anthracycline antibiotic, in nine patients with normal renal and hepatic functions and no third-space fluid accumulation. MCM was infused IV over 15 min at a dosage of 27.5, 40, or 50 mg/m2. Plasma and urine samples were collected up to 72 h. MCM and metabolites were assayed by thin-layer chromatography and quantified by specific fluorescence. The disappearance of total MCM-derived fluorescence from plasma followed first-order kinetics and lacked the rebound in total fluorescence that has been described for the structurally similar agent, aclacinomycin A. After 40-50 mg/m2, the peak MCM concentration in plasma was 1.67 +/- 0.61 microM; MCM disappeared from plasma in a triexponential fashion and was undetectable by 48 h after infusion. The area under the plasma concentration-time plot (AUC), including the infusion time, was 1.11 +/- 0.39 microM X h; plasma clearance of MCM was 1.50 +/- 0.88 l/min/m2. Five other fluorescent compounds were consistently observed in plasma. M2 was a contaminant present in the parent drug. P1 and P2 were conjugates of MCM and M2, respectively. G1 and G2 were aglycones. The peak concentrations of the metabolites were 25% or less or the peak concentration for MCM, but their persistence resulted in higher AUCs than that for MCM. For the dosage of 27.5 mg/m2, fewer data were available; but the pharmacokinetics of MCM and metabolites appeared to be similar to that at higher dosage. Urinary excretion of total fluorescence amounted to 8.0% +/- 1.6% of the total dose at 40-50 mg/m2, and to 7.0% +/- 2.3% at 27.5 mg/m2. No correlation was detected among the various pharmacokinetic parameters and toxicities encountered in these patients.

Abstract
A combination of cisplatin, methotrexate, bleomycin, and vincristine (CABO) was assessed in advanced epidermoid head and neck cancer. Among 72 patients with recurrent or metastatic disease and measurable lesions, there were 9 complete and 27 partial responses for an overall response rate of 50%. These results were adversely affected by prior surgery plus prior radiotherapy. The median response duration was 28 weeks (16-100+) in complete responders and 16 weeks (6-84) in partial responders. CABO was also administered to 56 patients with measurable, previously untreated, locoregional disease. In these patients, complete and partial response rates were 18% and 46%, respectively. Toxic effects were generally mild to moderate. In spite of its encouraging therapeutic efficacy, CABO is unlikely to be clearly superior to single-agent chemotherapy, at least in recurrent or disseminated disease. Increased effectiveness of CABO given as initial treatment suggests that chemotherapy might play an effective adjuvant role in carefully selected patients.

Abstract
We have investigated the metabolism and disposition, in mice, of 7-con-O-methylnogarol ( menogarol ; 7-OMEN), a new anthracycline antibiotic entering clinical trials. 7-OMEN, dissolved in 0.01 M glucuronic acid, was administered iv to mice (10 mg/kg). At specified times after injection, groups of mice were killed and 7-OMEN and metabolites were assayed in plasma and organs by HPLC. Plasma concentrations of 7-OMEN declined in triexponential fashion. The terminal t1/2 was 10.6 hr; the AUC was 10.13 microM X hr; the apparent Vc was 0.4 liter/m2, and the systemic clearance was 91.2 ml/min/m2. One metabolite, with the same HPLC characteristics as N- demethylmenogarol , was seen in plasma during the first 30 min after injection. 7-OMEN was distributed extensively to all tissues except brain. Initially, pulmonary concentrations of 7-OMEN were 15 times higher than those in any other organ and 30 times higher than those in plasma. Concentrations of 7-OMEN were the most persistent in spleen, kidney, and pancreas, and the least persistent in heart and liver. The AUC for 7-OMEN in organs was the greatest in lungs (605 nmol/g X hr), spleen (522 nmol/g X hr), and pancreas (430 nmol/g X hr), and least in heart (33 nmol/g X hr) and liver (60 nmol/g X hr). Kidneys and skeletal muscles had intermediate AUC values. In liver, two metabolites, one of which had the HPLC characteristics of N- demethylmenogarol , were seen. In other organs, the same metabolites were seen later and in small quantities.

Abstract
Rat liver microsomes under anaerobic conditions metabolize adriamycin (ADM) to 7-deoxyadriamycinol aglycone and 7-deoxyadriamycin aglycone. The metabolism of ADM and the concentration of cytochrome P-450 were not affected by preincubation with 2.76 mM cyclophosphamide. After preincubation of microsomes with 0.2 mM 4-hydroperoxycyclophosphamide, a prodrug of 4-hydroxycyclophosphamide, there was complete denaturation of the cytochrome P-450, and 22.8% inhibition of NADPH-cytochrome P-450 reductase. Under these conditions, the degradation of ADM was delayed (area under the concentration vs. time curve in micromolar X minutes: 15.6 +/- 2.4 for the controls, and 59.8 +/- 7.3 in the presence of 4-hydroperoxycyclophosphamide, P less than or equal to .005), 7-deoxyadriamycin aglycone increased progressively to reach a plateau at 20 min instead of showing a peak at 2 min and the formation of 7-deoxyadriamycinol aglycone was reduced. Microsomes from animals pretreated with cyclophosphamide (180 mg/kg i.p. once 4 days before sacrifice) showed a 24.0% reduction of NADPH-cytochrome P-450 reductase activity (P less than or equal to .02). This was accompanied by a decreased formation of 7-deoxyadriamycinol aglycone during the first 20 min of incubation (area under the concentration vs. time curve in micromolar X minutes: 68.0 +/- 15.7 in the controls, and 25.6 +/- 3.1 in the treated animals, P less than or equal to .005), whereas the formation of 7-deoxyadriamycin animals, P less than or equal to .005), whereas the formation of 7-deoxyadriamycin aglycone was not affected. These data indicate an interaction between the metabolism of cyclophosphamide and ADM in rats.
