Abstract
Background Immune checkpoint inhibitors (ICI) have become the cornerstone of treatment of certain malignancies. However, they can result in systemic toxicities including hepatitis. Societal guidelines recommend initial management with high dose steroids, then a slow taper as hepatitis resolves. However, there is significant variation in steroid response with some patients experiencing a relapse of hepatitis as steroid doses are tapered (“steroid relapse”). Purpose Identify clinical features that predict relapse, and to explore variations in steroid management, in patients with ICI hepatotoxicity. Method Patients receiving ICI in early phase clinical trials at Princess Margaret Cancer Centre, or treated at the Toronto Centre for Liver Disease for ICI hepatotoxicity, were included. Patients with CTCAE Grade (G)3 ICI hepatotoxicity (ALT >5 x ULN) were identified and clinical records reviewed for management and outcomes. Patients with an alternate cause for ALT elevation; who did not receive corticosteroids; or with HCC or viral hepatitis, were excluded. Result(s) Between August 2012 and December 2021, 36 patients with G3 ICI hepatotoxicity were identified. Most (23; 64%) had metastatic melanoma. Thirteen received anti-CTLA-4/PD-1; 18 anti-PD-1 or anti-PD-L1, and 5 anti-CTLA-4 monotherapy. All patients initially received corticosteroids (1-2mg/kg/day methylprednisone equivalent). Thirteen patients (36%) were steroid relapsers. Consistent steroid response was seen in 18 (50%). Age, sex, liver metastases, prior ICI exposure, peak ALT or starting dose of steroids (≤1.5 vs >1.5mg/kg/day methylprednisolone equivalents) did not predict relapse, although relapsers were more likely to have been treated with combination anti-CTLA-4/PD-1 (7 (54%) relapsers, vs 3 (16%) responders, p = 0.02). Relapse occurred after a median of 14.5 days (range 8-111), and after taper to median 54% (5-100) of initial steroid dose. In responders, ALT normalisation occurred after median 14 days (range 3-56). In 27 patients where sufficient data were available, societal guidelines on ALT thresholds to initiate steroid taper were followed in 13 (48%; 6 relapsers and 7 responders). However, initiation of steroid taper was delayed in responders compared to relapsers (after median 7 days (2-15) in responders vs 4 days (range 2-9) in relapsers, p = 0.04). Overall, 5 relapsers responded to re-escalation of steroids. Eight required additional treatment with MMF, and 4 required 3rd line therapy with Tacrolimus. Ultimately, hepatitis resolved in all patients. Conclusion(s) In patients with ICI hepatotoxicity, combination ICI therapy confers a higher risk of steroid relapse than monotherapy. There is significant heterogeneity in management of steroid dosing in patients with ICI hepatotoxicity. Delayed initiation of steroid taper may be associated with a reduced risk of relapse and warrants prospective evaluation as part of a standardised management algorithm.

Abstract
In 2021, the Food and Drug Administration Oncology Center of Excellence announced Project Optimus focusing on dose optimization for oncology drugs. The Methodology for the Development of Innovative Cancer Therapies (MDICT) Taskforce met to review and discuss the optimization of dosage for oncology trials and to develop a practical guide for oncology phase I trials. Defining a single recommended phase II dose based on toxicity may define doses that are neither the most effective nor the best tolerated. MDICT recommendations address the need for robust non-clinical data which are needed to inform trial design, as well as an expert team including statisticians and pharmacologists. The protocol must be flexible and adaptive, with clear definition of all endpoints. Health authorities should be consulted early and regularly. Strategies such as randomization, intrapatient dose escalation, and real-world eligibility criteria are encouraged whereas serial tumor sampling is discouraged in the absence of a strong rationale and appropriately validated assay. Endpoints should include consideration of all longitudinal toxicity. The phase I dose escalation trial should define the recommended dose range for later testing in randomized phase II trials, rather than a single recommended phase II dose, and consider scenarios where different populations may require different dosages. The adoption of these recommendations will improve dosage selection in early clinical trials of new anticancer treatments and ultimately, outcomes for patients.

Abstract
Background Adrenergic receptor stimulation is involved in the development of hypertension (htn) and has been implicated in cancer progression and dissemination of metastases in various tumours, including colon cancer. Adrenergic antagonists such as beta-blockers (bbs) demonstrate inhibition of invasion and migration in colon cancer cell lines and have been associated with decreased mortality in colorectal cancer (crc). We examined the association of baseline htn and bb use with overall (os) and progression-free survival (pfs) in patients with pretreated, chemotherapy refractory, metastatic crc (mcrc). We also examined baseline htn as a predictor of cetuximab efficacy. Methods Using data from the Canadian Cancer Trials Group co.17 study [cetuximab vs. best supportive care (bsc)], we coded baseline htn and use of anti-htn medications, including bbs, for 572 patients. The chi-square test was used to assess the associations between those variables and baseline characteristics. Cox regression models were used for univariate and multivariate analyses of os and pfs by htn diagnosis and bb use. Results Baseline htn, bb use, and anti-htn medication use were not found to be prognostic for improved os. Baseline htn and bb use were not significant predictors of cetuximab benefit. Conclusions In chemorefractory mcrc, neither baseline htn nor bb use is a significant prognostic factor. Baseline htn and bb use are not predictive of cetuximab benefit. Further investigation to determine whether baseline htn or bb use have a similarly insignificant impact on prognosis in patients receiving earlier lines of treatment remains warranted.

Abstract
BACKGROUND The acid-base, biochemical and hematological effects of crystalloid solutions have not been comprehensively evaluated in patients with liver resection. DESIGN multicenter, prospective, double-blind randomized controlled trial investigating the biochemical effects of Hartmann's solution (HS) or Plasmalyte-148 (PL) in 60 patients undergoing major liver resection. PRIMARY OUTCOME base excess immediately after surgery. SECONDARY OUTCOMES changes in blood biochemistry and hematology. RESULTS At completion of surgery, patients receiving HS had equivalent mean standard base excess (-1.7±2.2 vs. -0.9±2.3 meq/L; P=0.17) to those treated with PL. However, patients treated with HS were more hyperchloremic (difference 1.7 mmol/L, 95% CI: 0.2 to 3.2, P=0.03) and hyperlactatemic (difference 0.8 mmol/L, 95% CI: 0.2 to 1.3; P=0.01). In contrast, patients receiving PL had higher mean plasma magnesium levels and lower ionized calcium levels. There were no significant differences in pH, bicarbonate, albumin and phosphate levels. Immediately after surgery, mean PT and aPTT were significantly lower in the PL group. Intraoperatively, the median (IQR) blood loss in the PL group was 300 mL (200:413) vs. 500 mL (300:638) in the HS group (P=0.03). Correspondingly, the postoperative hemoglobin was higher in the PL group. Total complications were more frequent in the HS Group (56% vs. 20%, relative risk 2.8; 95% CI: 1.3 to 6.1; P=0.007). CONCLUSION In liver resection patients, HS and PL led to similar base excess values but different post operative plasma biochemistry and hematology values. Understanding of these effects may help clinicians individualize fluid therapy in these patients.

Abstract
BACKGROUND This phase I dose-escalation study investigated the maximum tolerated dose (MTD), safety, pharmacokinetics, pharmacodynamics (PDs), and preliminary antitumor activity of BGT226, a potent, oral dual phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin inhibitor. PATIENTS AND METHODS Fifty-seven patients with advanced solid tumors received BGT226 2.5-125 mg/day three times weekly (TIW). Dose escalation was guided by an adaptive Bayesian logistic regression model with overdose control. Assessments included response per RECIST, [18F]-fluorodeoxyglucose uptake, and phosphorylated-S6 in skin and paired tumor samples. RESULTS Three patients (125 mg cohort) had dose-limiting toxic effects (grade 3 nausea/vomiting, diarrhea). BGT226-related adverse events included nausea (68%), diarrhea (61%), vomiting (49%), and fatigue (19%). BGT226 demonstrated rapid absorption, variable systemic exposure, and a median half-life of 6-9 h. Seventeen patients (30%) had stable disease (SD) as best response. Nine patients had SD for ≥16 weeks. Thirty patients (53%) achieved stable metabolic disease as assessed by [18F]-fluorodeoxyglucose-positron emission tomography; however, no correlation between metabolic response and tumor shrinkage according to computed tomography was observed. PD changes suggested PI3K pathway inhibition but were inconsistent. CONCLUSIONS The MTD of BGT226 was 125 mg/day TIW, and the clinically recommended dose was 100 mg/day TIW. Limited preliminary antitumor activity and inconsistent target inhibition were observed, potentially due to low systemic exposure.

Abstract
OBJECTIVE This phase I study aimed to determine the maximal tolerated dose of cisplatin administered every 2 weeks with infusional 5-fluorouracil (5FU) and concurrent radiation therapy (RT) in patients after complete resection of gastric adenocarcinoma. METHODS Patients with resected stage IB to IV (M0) gastric adenocarcinoma were treated with 12 weeks of infusional 5FU (200 mg/m(2) daily) and with RT (45 Gy in 25 fractions starting on day 16). Cisplatin was administered in escalating doses (0, 20, 30, and 40 mg/m(2)) in weeks 1, 3, 5, and 7. In the final cohort, patients received an additional dose of cisplatin (40 mg/m(2)) in week 9. RESULTS Among the 34 patients [median age: 56 years (range: 31-77 years)] who were assessable for toxicity, 5 experienced dose-limiting toxicities: 1 sepsis (cohort 1), 1 fatigue (cohort 2), 3 upper gastrointestinal toxicity (1 in cohort 2, 2 in cohort 5). Cohort 5 exceeded the maximal tolerated dose. Median follow-up was 2.5 years (range: 0.3-5 years). The 3-year overall and relapse-free survival rates were 86% and 71% respectively; median survival was not reached. CONCLUSIONS Cisplatin was well tolerated in combination with infusional 5FU and RT, showing promising activity in the adjuvant treatment of gastric cancer. Infusional 5FU 200 mg/m(2) daily for 12 weeks with cisplatin 40 mg/m(2) in weeks 1, 3, 5, and 7 and with concurrent RT 45 Gy in 25 fractions, starting at day 16, is being explored in a phase II study at our institution.

Abstract
3558 Background: Temsirolimus (T) has encouraging activity in many malignancies, including endometrial cancer and a combination with carboplatin and paclitaxel would logical regimen for further development. This trial was designed to assess the safety and tolerability of this combination and expand experience at the recommended dose in pts with endometrial and ovarian cancers. Methods: A 3+3 dose escalation Phase I study has been conducted in pts with advanced solid malignancies suitable for carboplatin and paclitaxel chemotherapy who had not received more than 2 prior lines of chemotherapy. To date, 31 eligible pts with a median age of 59 have been treated and 27 are evaluable for toxicity. Pts were entered in 6 dose levels, with the first two levels administering T on Days 8 and 15 and the next 4 levels switching to a D1, 8 administration. Eighteen had received prior chemotherapy and 15 prior radiation. Results: Day 8, 15 administration of T was not feasible due to myelosuppression on day 15. The combination of carboplatin and paclitaxel on day 1 with T on D1 and 8 has been well tolerated, and patients have received a median of 5 cycles of therapy. At dose level 6 (T 25 mg D1 and 8, paclitaxel 175 mg/m2 D1, carboplatin AUC 6 D1) dose limiting toxicity (DLT) was seen in one of 6 pts treated to date (Gr 4 thrombocytopenia) and a second pt had a possible DLT ( Gr 3 fatigue in presence of baseline fatigue). This dose level is being expanded in 4 endometrial and ovarian cancer pts. The regimen is active: of the 26 patients with follow-up data, there have been 10 with partial response (38.5%; med. duration 7.1 mo [1.0–12.7]) and 12 with stable disease (46%; med. duration 6.9 mo [1.3- 7.8]). One patient had progressive disease and three were inevaluable. Conclusions: The results indicate this combination is well tolerated and requires additional assessment in a Phase II setting. The recommended Phase II dose will be dose level 6 provided no further DLTs are observed in the additional 4 patients entered. [Table: see text] No significant financial relationships to disclose.

Abstract
e13509 Background: E7389 (E) is a synthetic analogue of halichondrin B, an investigational tubulin-based antimitotic drug. Gemcitabine (G) is a nucleoside analogue clinically active in several human tumours. These two drugs exhibit synergistic cytotoxic effects against the H522 non-small cell lung cancer (NSCLC) xenografts. Methods: A phase I study of these two drugs in combination was initiated in patients with advanced solid tumours. Two prior chemotherapy regimens for metastatic disease were allowed. Results: Patient characteristics: male 11/female 10; median age 59 (range 28–84); performance status 0 /1/2: n=1/13/7; prior chemotherapy 21, prior radiotherapy 7, prior immunotherapy 1; tumour types: ovarian cancer 3, endometrial cancer 3, NSCLC 3, gastric/esophageal adenocarcinoma 3, miscellaneous 9. Total number of cycles given 52, median cycles/patient (range) 2 (1, 8). Cohort (CT) 1: E/G given days 1,8,15 q28 days. Due to DLT, regimen changed in CT 2 with E/G given days 1, 8 q21 days. Cycles (C) given: median 2 range 1–8, total 52. Response: partial response 1 (ovarian cancer), stable 8 [minor response 4 (NSCLC 2, endometrial cancer 1, head and neck cancer 1)], progression 8, inevaluable 4. Conclusions: Further phase II investigation of this regimen should be considered at a dose of E 1.0 g/m2/G 1000 mg/m2 q 3 weeks. [Table: see text] No significant financial relationships to disclose.

Abstract
6072 Background: Due to their anatomical complexity, the interactive effects of multiple treatment modalities, the difficulties in differentiating scar tissues versus residual disease and second cancers versus tumor recurrence, LA-HNSCC represent a challenging disease for the reporting of endpoints and the tracking of failures. Methods: We retrieved all randomized trials that began accrual on or after 1978, and enrolled previously untreated nonmetastatic HNSCC patients receiving primary (chemo)radiotherapy. The reporting of endpoints and the tracking of failures in these trials were analyzed. Failures were defined as events meeting a pre-specified endpoint definition. Results: Forty trials involving 13,892 patients fulfilled our inclusion criteria. A total of 125 endpoints were identified: primary versus secondary = 34:91, survival-based (e.g., overall survival [OS]) versus surrogate (e.g. locoregional control [LRC]) = 47:78. In 6 trials, no primary endpoint was identified. LRC and OS accounted for 70% of primary endpoints. All but one trial reported at least one secondary endpoint, with a median of 2 per trial (range: 0–5), and as many as 17 different types of secondary endpoints were reported. Among 72 endpoints tracking locoregional failures, 21/72 (29%) did not define locoregional failure, while 46/72 (64%) specified the absence of complete response as a failure. Whether salvage surgery or elective node dissection was performed or not was reported in less than half of the trials. Furthermore, it was usually not specified if residual disease found during these procedures would account for failure or not. The means (i.e. clinical and/or radiological examinations) to ascertain failures and the protocol-specified timing to track failures were reported in 41% and 67% of surrogate endpoints, respectively. The tracking of other types of failure beyond the first failure is not reported by any of the trials. The reporting of second cancers was found in 15/40 (38%) trials, whereas the duration of follow-up was quantified in 31/40 (78%) trials. Conclusions: These results demonstrate the vast heterogeneity in endpoint reporting and tracking of failures in clinical trials of LA-HNSCC. No significant financial relationships to disclose.

Abstract
Across the world, there are basically two types of prehospital emergency medical service systems. In Anglo-American countries, acute out-of-hospital care for critically ill patients is provided by paramedics, while in most European countries, this role is filled by anaesthetists or emergency specialists. Intuitively, prehospital anaesthetists seem to be a useful adjunct for improved patient outcome but at greater expense. Which system provides the best medical care for critically ill patients in the prehospital setting? Is it purely an economic issue?

Abstract
6569 Background: New phase II trial designs have been proposed to accommodate the non-cytotoxic nature of molecularly targeted agents. In particular, the use of alternative endpoints and controls has been suggested. The objectives of this survey are to review the designs of contemporary phase II trials, to compare trials of cytotoxic versus non-cytotoxic regimens, and to identify predictors of acceptance for presentation. Methods: Abstracts of phase II trials of systemic anticancer therapy published in the 2005 ASCO Proceedings were hand searched. The trial context, type of intervention, trial design, endpoints, and completeness of reporting were assessed. Results: Our search yielded 565 abstracts: 72% were multi-center, 44% North American, 25% clearly identified as industry-sponsored, the median number of patients was 44 (range 8–346). Only 83% explicitly reported the study phase, 29% the primary endpoint, 11% the number of stages, and 5% the statistical design. For design properties, 16% used multiple arms and 6% used enrichment. Of trials reporting the primary endpoint, 48% used radiological or marker response and 22% time-to-event endpoints. The median number of endpoints was 4 (range 1–8). Non- cytotoxic regimens, which included targeted agents, hormone- or immunotherapy, constituted 22% of the trials reviewed, purely cytotoxic regimens 60%, the remaining 18% contained combinations of both. Trials of non-cytotoxic and combination regimens were more likely to report the primary endpoint (p=0.02), use time-to-event endpoints (p=0.006), have multiple arms, use enrichment, be conducted in North America, be industry-sponsored, and be accepted for oral or poster presentation (all p<0.001). Other predictors of publication type in multivariate analysis were multi-centricity, higher number of patients, industry involvement, and being conducted in North America (all p<0.05). Conclusions: Design properties of contemporary phase II trials of non-cytotoxic agents differ from trials of cytotoxic chemotherapy, and are more likely to be accepted for presentation at ASCO. Proposed new trial designs start to be more widely adopted. Most abstracts incompletely report design properties. No significant financial relationships to disclose.

Abstract
3576 Background: VOR (suberoylanilide hydroxamic acid; SAHA) is a small molecule inhibitor of histone deacetylase (HDAC) that binds directly to the enzyme’s active site in the presence of a zinc ion. Aberrant HDAC activity has been implicated in a variety of cancers. The combination of 5-fluorouracil and VOR is synergistic in preclinical tumor models. Methods: This phase I study evaluated safety, tolerability, and the recommended phase II dose (RPTD) of VOR and CAP in pts with advanced solid tumors. VOR was administered orally daily while CAP was administered orally bid on days 1–14 of a 21 d cycle. Results: Three dose levels have been evaluated (VOR (mg/d)/CAP (mg/bid)): 300/750, 300/1,000 and 400/1,000. Twenty-three pts have been treated: 6M/17F, median age 59 (range 41–73), ECOG 0:1:2 = 9:13:1, prior therapy 1:2:3 or more = 3:7:13. Pts had colorectal cancer (n=6), nasopharyngeal (n=3) and various other tumors. A total of 104 cycles have been administered, with median = 2 (range 1–15). One dose limiting toxicity (DLT) (grade 3 diarrhea) occurred in 6 patients at dose level 1. No DLT were observed at dose level 2, and 2 DLTs (grade 3 fatigue and grade 3 nausea/vomiting) occurred at dose level 3. RPTD was determined to be VOR 300 mg/d and CAP 1,000 mg/bid. Most common toxicities of any grade and at least possibly attributable (n=22) are: thrombocytopenia (59% of pts), fatigue (55%), nausea (55%), vomiting (50%), hypoalbuminemia (45%), anemia (41%), diarrhea (41%), anorexia (41%), elevated creatinine (36%), lymphopenia (36%), hyponatremia (36%), and hyperglycemia (36%). Common grade 3 toxicities included: hand-foot syndrome (23% of pts), diarrhea (14%), fatigue (14%), and lymphopenia (14%). One pt died on study from ventricular fibrillation due to sotalol and hypocalcemia from pre-existing hypoparathyroidism. Five patients with various tumor types had PR (2 confirmed, 3 unconfirmed) (2 nasopharyngeal, 1 each of ovarian, endometrial and squamous cell carcinoma of head and neck). In addition, disease stabilization was seen in 12 patients. Conclusions: VOR and CAP are well tolerated, and this combination is active in several tumor types. Further evaluations of VOR and CAP are warranted. No significant financial relationships to disclose.

Abstract
2554 Background: X + O in combination (XELOX) has similar efficacy to FOLFOX-4 in untreated MCRC patients (pts) [1]. The addition of A to irinotecan/5-FU/LV improves progression-free survival (PFS) and overall survival [2], and the potential improvement of adding A to XELOX in MCRC is currently being investigated. Here we present the first PK evaluation of the effects of X on O, O on X, X+A on O, and O+A on X in a multicenter open-label study of pts with untreated MCRC. Methods: Pts received treatment for up to 16 cycles with blood samples for PK analysis taken during cycles 1–3. Treatment: cycle 1: X 1000 mg/m2 orally on morning of d1, O 130 mg/m2 i.v. infusion d2, X 1000 mg/m2 bid orally d5–14, rest d15–21; cycle 2: O 130 mg/m2 i.v. infusion d1 + X 1000 mg/m2 bid orally d1–14, rest d15–21; cycle 3 (XOA): A 7.5 mg/kg i.v. infusion d1 + O 130 mg/m2 i.v. infusion d1 + X 1000 mg/m2 bid orally d1–14, q3w. Treatment with the XOA regimen continued for a further 13 cycles. Safety was evaluated throughout. Results: 36 pts were enrolled; 26 pts completed cycles 1–3 and were evaluable for PK analysis; all pts were evaluable for safety. Baseline characteristics were: M/F 42%/58%; median age 60 years (range 22–74). The primary parameter for PK analysis of X, AUC0-8 of 5’-DFUR, was slightly lower in cycle 2 d1 (XO) and cycle 3 d1 (XOA) vs. cycle 1 d1 (X) (10% and 13% lower, respectively, with CV 27–33%); a decrease in the Cmax of 5’-DFUR was also observed (26% and 36% lower, respectively, with CV 48–54%). However these differences were not considered clinically important. The primary parameter for PK analysis of O, AUC0-8 of free platinum, was very similar among cycle 2 d1 (XO), cycle 3 d1(XOA), and cycle 1 d2 (O), with geometric mean ratios very close to 1. Treatment with X, O and A in combination was generally well tolerated. Conclusions: No large differences in exposure of X or its metabolites, free platinum or total platinum occur when X, O and A are administered in combination. This provides further support for the development of the above dosing regimen in MCRC. References: 1. Cassidy J et al. J Clin Oncol 2004;22:2084–91. 2. Hurwitz H et al. N Eng J Med 2004;350:2335–42.

Abstract
14030 Background: Nimotuzumab (N) is a humanized mAb against the EGFR extracellular ligand binding domain. Although well tolerated when combined with radiotherapy in previous studies and lacking usual toxicities of EGFR-targeting agents, the pharmacodynamics (PD) of N has not been elucidated. This phase I study was designed to evaluate the safety, tolerability and PD of N. Methods: Eligibility criteria included advanced solid tumors refractory to standard therapy and ECOG PS = 0 - 2. IV N was administered weekly x 6 and then every other week (6 weeks = 1 treatment cycle). Tumor, skin and liver biopsies obtained pre- and 2 and 7 weeks post-treatment were evaluated using computer-based, whole mount assessment of immunohistochemical staining. Results: Accrual was completed 21/09/06, 17 patients (11m/6f, median age 63, 13 colorectal cancer, ECOG 0:1:2 = 6:10:1, prior therapy 1:2:3+ = 2:6:9) were registered and 16 patients were treated on 4 dose levels (100, 200, 400 and 800 mg) for a total of 43 treatment cycles (1 patient deemed ineligible after registration did not receive study therapy). Treatment was well tolerated. One dose-limiting toxicity was observed (dose level 1 - grade 3 fatigue possibly attributable to N) . Skin toxicity was mild (Gr 1/2 in 7/1 patients). Confirmed stable disease was seen in 6 patients, a confirmed partial response in 1 patient with prolonged progression-free status observed in 3 patients for 5.8, 14.1 and 18.7 months (the latter two remain on study). Baseline and week 2 biopsies of tumor/skin/liver were evaluable in 12/13/7 pts. Week 7 tumor/skin/liver biopsies in initially responding or stable patients were evaluable in 6/8/6 pts. Post treatment (week 2), EGFR staining decreased in 8/12 matched tumor [mean ratio (post/pre): 0.79 range: (0.37, 1.91)], 8/13 skin [0.96 (0.40, 1.31)] and 5/7 liver [0.88 (0.62, 1.17)] biopsies. No significant relationship was detected between pre/post-treatment EGFR expression with either response or toxicity. Evaluation of downstream targets of EGFR (in tumor, skin and liver) is ongoing and will be presented. Conclusions: Overall nimotuzumab was well tolerated and exhibits mild skin toxicity. Prolonged progression free-survival was observed in 3/16 of these heavily pre-treated patients. No significant financial relationships to disclose.

Abstract
13054 Background: Nimotuzumab is a humanized mAb against the extracellular ligand binding domain of EGFR. Although well tolerated when combined with radiotherapy in previous studies, the pharmacodynamics (PD) of nimotuzumab has not been elucidated. This phase I study was designed to evaluate the safety, tolerability and PD of nimotuzumab. Methods: Eligibility criteria included advanced solid tumors refractory to standard therapy and performance status of ECOG 0–2. Nimotuzumab was administered intravenously weekly × 6 and then every other week (6 weeks = 1 treatment cycle). Tumor and skin biopsies were obtained at baseline and after 2 weeks of treatment. Results: To date, 9 patients (7 m/2 f, median age 60, 7 colorectal cancer, ECOG 0:1:2 = 5:3:1, prior therapy 1:2:3+ = 1:3:5) have been treated on the first 2 dose levels (100 mg and 200 mg) for a total of 13 treatment cycles. The most common toxicities, mainly grade 1- 2, were lymphopenia (n = 8 patients), fatigue (n = 8), abnormal liver function tests (n = 7) and anemia (n = 6). Observed grade 3 toxicities include: pain (n = 3), hyponatremia (n = 2), elevated ALP (n = 2), fatigue (n = 1), hyperglycemia (n = 1) and hyperkalemia (n = 1). One patient at the first dose level experienced grade 3 fatigue, at least possibly attributable to nimotuzumab, and thus considered as a dose-limiting toxicity (DLT). No DLT were observed in the expanded cohort and dose level 2. No skin toxicities were observed. Stable disease was seen in 3 patients with colorectal cancer. PD from tumor and skin biopsies will be presented, and may clarify the reason for the lack of skin toxicity. Conclusions: Overall nimotuzumab was well tolerated, with disease stabilization observed in heavily pretreated patients. Accrual continues at dose level 3 (400 mg) with one further planned dose level (800 mg). [Table: see text]

Abstract
3081 Background: GX15–070 is an antagonist of the BH3-binding groove of the bcl-2 family of anti apoptotic proteins. GX15–070 activates apoptosis in vitro and exhibits clinical activity in chronic lymphocytic leukemia (O’Brien et al, ASH 2005) with a recommended phase II dose of 28 mg/m2 every 3 weeks with DLT of grade 3 infusional CNS toxicities. Methods: In a standard titration design, 4 cohorts of 3 patients (pt) were treated with 5mg/m2 - 14 mg/m2 IV infused over 3 hours, weekly. Each cycle of therapy consisted of 4 weekly infusions. Pharmacokinetics (PK) and pharmacodynamic (PD) response based on plasma oligonucleosomal DNA levels were evaluated. Results: N=15 pts were treated. Median age was 58 (range 24–71). Median number of prior regimens was 4 (range 1–11). A total of 105 infusions (26 cycles) was administered. GX15–070 underwent first order elimination kinetics with a short initial distribution phase (α t1/2=0.6 h), followed by a longer elimination γphase (t1/2=43.8 h). At the 14 mg/m2 dose level, median C max and AUC values were 98 ng/ml and 276 ng.hr/ml, respectively. The coefficient of variation was low at 38%. Adverse events have mostly been observed during or shortly after the infusion and have been transient. The most common pertain to the central nervous and gastro-intestinal system (drowsiness, euphoria, ataxia, and abdominal pain). Most toxicities were mild to moderate, with the exception of grade 3 pain experienced by 2/2 pts with Hodgkin’s disease, that resolved rapidly but resulted in treatment discontinuation in 1 patient. One episode of Grade 3 infusional CNS toxicity was reported at 14 mg/m2 requiring the inclusion of 6 patients with no further DLT. No neutropenia, thrombocytopenia or lymphopenia have been reported. The MTD has not been reached. Mean increase in plasma oligonucleosomal DNA was 36 fold (range 0–182 fold) over baseline. Best response to treatment to date : SD ≥ 8 weeks (4); PD (5); too early (6). Conclusion: Weekly GX15–070 as been well tolerated at doses showing biological activity. Dose escalation will be pursued up to 28 mg/m2 weekly. No significant financial relationships to disclose.

Abstract
Carcinoid tumours are relatively rare and, in general, slow growing. They can be "non-functioning" tumours, presenting as a tumour mass, or "functioning" tumours secondary to the production of several biopeptides leading to the carcinoid syndrome. Though these tumours represent 0.25% of an oncology practice, a proper understanding of the clinical course of the disease and of the importance of appropriate diagnostic and therapeutic measures is very important. Proper patient management can lead to cure, particularly if the tumour can be fully resected, or to long-term palliation with medical treatment or cytoreductive surgery, or both, with significant prolongation of survival. A good understanding of the use of somatostatin analogues to achieve effective symptomatic control and of the importance of adequate follow-up and cardiac monitoring to prevent or effectively treat cardiac complications can contribute significantly to optimal control of this complex disease, ultimately improving the quality of life of affected patients. This article, developed by a group of Canadian experts, provides a framework that will assist clinicians in taking an optimal approach to managing their patients with carcinoid tumour.

Abstract
BACKGROUND BAY 43--9006, an oral multi-kinase inhibitor, targets serine-threonine kinases and receptor tyrosine kinases, and affects the tumor and vasculature in preclinical models. Based on its pharmacologic effect, it may be a useful cancer treatment. This study determined the maximum tolerated dose (MTD) of BAY 43-9006 in 42 patients with advanced, refractory metastatic or recurrent solid tumors. Dose-limiting toxicities (DLTs), safety, pharmacokinetics and tumor response were also evaluated. PATIENTS AND METHODS In this open-label, phase I, dose-escalation study, BAY 43--9,006 was administered orally in repeated cycles of 35 days (28 days on/7 days off). Eight doses were investigated: from 50 mg every fourth day to 600 mg twice daily. Treatment continued until unacceptable toxicity, tumor progression or death. RESULTS The MTD was 400 mg twice daily. BAY 43-9006 was well tolerated, with mild to moderate toxicities; only six patients discontinued study therapy due to adverse events. DLTs consisted of hand-foot skin reaction in three of seven patients receiving 600 mg twice daily. Stable disease was achieved in 22% of patients; median duration of stable disease was 7.2 months. Consistent with its observed half-life of approximately 27 h, BAY 43-9, 006 accumulated on multiple dosing. Increases in exposure were less than proportional to the increases in dose. CONCLUSIONS Results indicate that further clinical investigation of BAY 43--9006 is warranted, and suggest it could be a promising future therapy for patients with cancer.
