A Phase I Study of an MPS1 Inhibitor (BAY 1217389) in Combination with Paclitaxel Using a Novel Randomized Continual Reassessment Method for Dose Escalation. Clin Cancer Res 2021; 27:6366-6375. [PMID: 34518310 DOI: 10.1158/1078-0432.ccr-20-4185] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 01/05/2021] [Accepted: 09/09/2021] [Indexed: 11/16/2022]
Abstract
PURPOSE Monopolar spindle 1 (MPS1) kinase inhibitor, BAY 1217389 (BAY) synergizes with paclitaxel. This phase I study assessed the combination of BAY with paclitaxel using a novel randomized continuous reassessment method (rCRM) to improve dose determination. PATIENTS AND METHODS Patients with solid tumors were randomized to receive oral BAY (twice daily 2-days-on/5-days-off) with weekly paclitaxel (90 mg/m2) or paclitaxel monotherapy in cycle 1. Dose escalation was guided by CRM modeling. Primary objectives were to assess safety, establish the MTD of BAY, and to evaluate the pharmacokinetic profiles for both compounds. Simulations were performed to determine the contribution of the rCRM for dose determination. RESULTS In total, 75 patients were enrolled. The main dose-limiting toxicities were hematologic toxicities (55.6%). The MTD of BAY was established at 64 mg twice daily with paclitaxel. Inclusion of a control arm enabled the definitive attribution of grade ≥3 neutropenia to higher BAY exposure [AUC0-12 (P< 0.001)]. After determining the MTD, we included 19 patients with breast cancer at this dose for dose expansion. Other common toxicities were nausea (45.3%), fatigue (41.3%), and diarrhea (40.0%). Overall confirmed responses were seen in 31.6% of evaluable patients. Simulations showed that rCRM outperforms traditional designs in determining the true MTD. CONCLUSIONS The combination of BAY with paclitaxel was associated with considerable toxicity without a therapeutic window. However, the use of the rCRM design enabled us to determine the exposure-toxicity relation for BAY. Therefore, we propose that the rCRM could improve dose determination in phase I trials that combine agents with overlapping toxicities.

Abstract
Background Neoadjuvant chemotherapy improves survival of locally advanced gastric cancer patients. However, benefit is limited and the best regimen remains controversial. Objectives Our primary objective of this prospective, multicenter phase 2 study was to evaluate the pathological complete response rate (PCR) with 2 cycles of docetaxel and capecitabine. Methods To be eligible, patients had to have histologically documented gastric cancer, a ECOG performance status 0 or 1, T3or4 Nany M0 staging after oesophagogastroduodenoscopy (OGD), endoscopic ultrasound (EUS), CT scan of thorax and abdomen, and negative laparoscopic examination and peritoneal washing. Eligible patients received two cycles of intravenous docetaxel 60 mg/m2 on day 1 and oral capecitabine 900 mg/m2 two times per day from day 1 to day 14 every 3 weeks. We evaluated the response by CT scan and EUS. The patients underwent curative resection with D2 lymphadenectomy subsequently. Results 18 patients were enrolled in the study: 66% were male and the median age was 60 years. 17 patients had T3 disease at diagnosis. There was no pCR noted. 4 patients had a partial response of 22% (95% CI: 7–42%), 8 patients had stable disease and 3 patients had disease progression. The median survival was 17.1 months with 3 long-term survivors after at least 3 years of follow-up. The treatment was well tolerated with neutropenia being the most common toxicity. We observed 22% grade III and 33% grade IV neutropenia, but no neutropenic fever or death was observed from chemotherapy. Conclusion Neo-adjuvant chemotherapy with docetaxel and capecitabine has limited activity against GC. More effective treatment regimens are needed urgently. Trial registration number NCT00414271.

Abstract
Taxanes are core therapeutic components for several advanced malignancies, and have been studied extensively in pancreatic adenocarcinomas with mixed results. Although the triplet combination FOLFIRINOX improves outcomes for patients with metastatic disease, it is compounded by significant toxicity, and novel regimens, rationally designed and based on thorough mechanistic activity on the tumor targets, are clearly needed. Solvent-based taxanes, docetaxel and paclitaxel, have little activity as single agents, but combinations with fluoropyrimidines and gemcitabine show efficacy, albeit they have not undergone testing in phase III trials. Pancreatic cancer is characterized by an abundant desmoplastic, fibroinflammatory and hypoperfused stroma, which has been blamed for its overall chemoresistance. Nanoparticle bound paclitaxel (nab-paclitaxel) has been pharmacologically designed as a novel water-soluble agent, with improved therapeutic index compared with the cremophor-based formulation, capable of achieving higher systemic exposure. In preclinical systems, when combined with gemcitabine, nab-paclitaxel increased intratumoral gemcitabine delivery, possibly due to inducing stromal 'collapse' and through inhibition of the gemcitabine-catabolizing enzyme cytidine deaminase. Most recently, the combination of nab-paclitaxel and gemcitabine demonstrated significant survival benefit with good tolerability in metastatic pancreatic cancer in the phase III trial MPACT, and now represents one of the gold-standard regimens for this disease. Although taxanes are overall potent chemotherapeutics for various cancers, it is clear that for meaningful results in pancreatic adenocarcinomas, rationally designed combinations and novel technologies for drug delivery are likely to be most successful.

Abstract
PURPOSE Docetaxel and capecitabine combination is synergistic in preclinical models. We investigated the efficacy and toxicity of this combination as second-line chemotherapy in patients with metastatic pancreatic adenocarcinoma (mPC), pretreated with gemcitabine-based chemotherapy. METHODS Eligible patients were treated with capecitabine 800 mg/m(2) orally PO bid on days 1-14 in combination with intravenous docetaxel 30 mg/m(2) on days 1 and 8 of each 21-day cycle. The primary end point was overall response rate. Using a three-stage sequential design, two interim analyses for early stopping due to lack of efficacy were planned and conducted after 13 and 26 patients were accrued. Secondary end points included time to treatment failure, progression-free survival (PFS), overall survival (OS) and 50 % drop in CA19-9 levels. RESULTS Forty-three patients were evaluable for toxicity and 42 evaluable for response, at a median age of 64 years. The majority of patients (74 %) had ECOG PS 0-1. Six patients (14 %) achieved a partial tumor response, and stable disease for ≥2 cycles was observed in 59 % of patients (n = 25). Thirty-five percent (n = 11/31) of patients had a ≥50 % decrease in CA19-9 levels. The median PFS was 3.7 months (95 % CI 2.1-4.3 months), and the median OS was 5.3 months (95 % CI 4.3-8.6 months). Treatment was generally well tolerated. Grade 3 toxicity and grade 4 toxicity were seen in 45 and 5 % of patients, respectively. One patient had a potential treatment-related mortality. CONCLUSIONS The combination of capecitabine and docetaxel is active and well tolerated in mPC patients pretreated with gemcitabine-based therapy.

Abstract
BACKGROUND This phase ii clinical trial examined the activity of a metronomic dosing schedule of docetaxel and capecitabine chemotherapy in patients with advanced breast cancer. Patients also received daily oral celecoxib in an effort to improve outcome measures and to ameliorate some of the common side effects of chemotherapy. METHODS Patients received docetaxel at a starting dose of 15 mg/m² weekly, oral capecitabine 1250 mg/m² once daily, and oral celecoxib 200 mg twice daily. The primary endpoint was clinical benefit: percentage of patients experiencing either an objective response or stable disease (sd) for more than 6 months. In the absence of significant neutropenia, the dose of docetaxel was escalated after 4 and 8 weeks of treatment. Therapy was given until disease progression or development of unacceptable toxicity. The level of thymidine phosphorylase expression in peripheral white blood cells of patients was measured before and during treatment to determine the effect on this capecitabine-activating enzyme. RESULTS Of 47 patients enrolled, 38 (81%) completed treatment to a disease endpoint. No complete responses were achieved, but 13 of the 38 patients (34%) experienced a partial response, and another 3 patients (8%) experienced sd for more than 6 months. The clinical benefit rate was therefore 42% (95% confidence interval: 27% to 57%). The median time to disease progression for all evaluable patients was 3.6 months (range: 0.9-21.7 months). The most common nonhematologic toxicities were diarrhea, plantar- palmar erythrodysesthesia, fatigue, mucositis, and vomiting. Most patients (89%) received combination chemotherapy until disease progression. CONCLUSIONS The present study demonstrates that metronomic docetaxel-capecitabine chemotherapy with daily celecoxib can produce significant anticancer activity, with predictable toxicity. Efficacy fell short of expectations, with outcome measures being similar to those obtained when the study agents are given in conventional dosing. Furthermore, there is mounting evidence to indicate that a low dose of taxanes fails to induce thymidine phosphorylase expression, an effect believed to be important in achieving therapeutic synergism when taxanes are given concurrently with capecitabine.

Abstract
OBJECTIVE To evaluate the efficacy and safety of docetaxel plus capecitabine (DC) combination as salvage treatment in anthracycline- and taxane-pretreated patients with metastatic breast cancer (MBC). PATIENTS AND TREATMENT Patients with MBC who had disease progression after initial chemotherapy with anthracyclines (n = 29; 100 %) and taxanes (n = 11; 37.9 %) were treated with oral capecitabine 950 mg/m(2) twice daily on days 1-14 and docetaxel 75 mg/m(2) on day 1 every 3 weeks. Nineteen (65.5 %) patients received this regimen as second line and 10 (34.5 %) as ≥3rd line of therapy. All patients were evaluable for response and toxicity. RESULTS Complete response occurred in two (6.9 %) patients and partial response in eleven (37.9 %) for an overall response rate of 44.8 % (95 % CI 26.7-62.9 %). Eleven women (37.9 %) had stable disease and five (17.2 %) progressive disease. Of the eleven patients previously treated with anthracyclines and taxanes, five (45.5 %) responded to DC combination. The median duration of response was 5.7 months (range 3.4-64.2), the median time to disease progression 9.3 months (range 1.2-58), and the median overall survival 25.5 months. No toxic death occurred. Neutropenia grade 4 occurred in 58.6 % of patients and three of them (10.3 %) developed neutropenic fever. Non-hematological toxicities were manageable with grade 3 hand-foot syndrome occurring in 6.9 % of the patients, fatigue in 3.4 %, and neurotoxicity in 3.4 %. CONCLUSION The DC combination is a valuable regimen as salvage treatment in anthracycline- or anthracycline and taxane-pretreated patients with MBC.

Abstract
BACKGROUND To assess the role of Thymidine Phosphorylase and β-tubulin III in clinical outcome of Chinese advanced gastric cancer patients receiving first-line capecitabine plus paclitaxel. METHODS The clinical data and tumor biopsies prior treatment from 33 advanced gastric cancer patients receiving capecitabine plus paclitaxel (cohort 1, experimental group) and 18 patients receiving capecitabine plus cisplatin (cohort 2, control group) in Beijing Cancer Hospital from July 2003 to December 2008 were retrospectively collected and analyzed for Thymidine Phosphorylase and β-tubulin III expressions by immunohistochemistry. The relationships between expressions of biomarkers and response or survival were determined by statistical analysis. RESULTS The median age of 51 patients was 57 years (range, 27-75) with male 34 and female 17, and the response rate, median progression-free survival and overall survival were 43.1%, 120d and 265d. Among cohort 1, the response rate, median progression-free survival and overall survival in β-tubulin III positive (n = 22) and negative patients (n = 11) were 36.4%/72.7% (positive vs negative, P = 0.049), 86d/237d (P = 0.046) and 201d/388d (P = 0.029), respectively; the response rate (87.5% vs 14.3%, P = 0.01) and median progression-free survival (251d vs 84d, P = 0.003) in Thymidine Phosphorylase positive & β-tubulin III negative patients (n = 8) were also significantly higher than those in Thymidine Phosphorylase negative & β-tubulin III positive patients (n = 7). There was no correlation between β-tubulin III expression and response or survival among cohort 2 (n = 18). CONCLUSIONS In Chinese advanced gastric cancer, Thymidine Phosphorylase positive & β-tubulin III negative might predict response and prognosis to capecitabine plus paclitaxel chemotherapy. Further prospective evaluation in large samples should be performed to confirm these preliminary findings.

Abstract
UNLABELLED This Phase II trial investigated the combination paclitaxel (P) and uracil-tegafur (UFT) in patients with metastatic breast cancer (MBC). METHODS Main eligibility criteria included HER-2 negative MBC, ECOG performance status of 0-2, exposure to 1-2 prior chemotherapy regimen in the metastatic setting, previous exposure to an anthracycline containing regimen either at metastatic or adjuvant setting. Each 35-day cycle consisted of P at 80 mg/m(2) by intravenous infusion on days 1, 8, 15, 22 and 29 and oral UFT at 300 mg/m(2) TID (three time a day) from days 1-28 and oral folinic acid at 90 mg QD (one a day). RESULTS Between March 2003 and December 2007, 31 patients were enrolled. Median age was 66 years (range 44-78). All tumours were HER-2 negative and 7% were triple negative (ER, PgR, HER-2). The majority of patients had visceral disease (81%). All patients had received an anthracycline containing regimen and 74% had a previous docetaxel containing treatment. Median of 4 and 3 cycles of P and UFT were administered with a relative dose intensity of 85.3% and 94.3%, respectively. Twelve (40%)(95% CI: 22.5-57.5) confirmed ORR were observed. Stable and progression disease were reported in 43% and 17% of cases. Median Response duration was 8.4 month (95% CI: 4.9-11.7), median Time to progression was 9.5 months (95% CI: 6.6-13.8) and median Overall Survival was 23.5 months (95% CI: 16.8-37.2). Thirteen pts (43%) experienced a grade 3 or 4 adverse events (AEs): One death occurred related to the study drugs (febrile neutropenia). Chemotherapy was discontinued due to toxicity in 30% of pts CONCLUSIONS Accrual was closed in January 2008 due to concerns regarding the degree and accumulative nature of AEs. Nonetheless, the ORR is encouraging and warranted further studies with adapted doses and schedules.

Abstract
Capecitabine (N -pentyloxycarbonyl-5-deoxy-5-fluorocytidine), an oral prodrug of 5-fluorouracil, has provided compelling efficacy data for the treatment of metastatic breast cancer and stage III or IV colorectal cancer, both as monotherapy and in combination regimens. The preferential conversion of capecitabine to 5-fluorouracil in neoplastic tissues renders this fluoropyrimidine particularly appealing for clinical use. The enzyme thymidine phosphorylase, which mediates the final step of the capecitabine activation pathway, is expressed in higher concentration in neoplastic than in healthy tissues. This makes capecitabine more tumor specific than other chemotherapeutic agents. Accordingly, capecitabine is generally well tolerated. In particular, the incidence of myelosuppression and alopecia is low, and the most common side effects, hand-foot syndrome and diarrhea, are usually manageable. Given its good toxicity profile, capecitabine was assessed in combination with several chemotherapeutic or biologic agents. In addition, the observation that thymidine phosphorylase is upregulated after treatment with other anticancer drugs, namely taxanes, provided a rationale for the prominent antitumor activity recently observed for the combination of capecitabine with these agents. This review provides an evidence-based update of clinical trials investigating the role of capecitabine in the treatment of breast and colorectal cancer, with special emphasis on pharmacological and safety issues that form the basis of currently used schedules.

Abstract
Background A synergistic cytotoxic effect has been hypothesized for taxanes and capecitabine, a prodrug of 5-fluorouracil. Based on preclinical studies, this synergism has been attributed to an up-regulation of the enzyme thymidine phosphorylase (TP). Beside tumour tissue, TP is highly expressed in white blood cells, possibly causing increased hematotoxicity, when taxanes are combined with capecitabine. So far, this hypothesis has not been investigated in humans. Methods A total of 128 consecutive blood samples were collected from eight patients with advanced breast cancer receiving paclitaxel weekly at a dose of 80 mg/m2. To assess the expression of TP in blood cells, samples were collected prior to first therapy, at the end of infusion, and up to 15 days thereafter. This procedure was repeated during the sixth application of paclitaxel. After isolation of the peripheral mononuclear blood cells, the expression of TP was assessed by ELISA. In parallel, paclitaxel level in plasma was evaluated at three selected time points as pharmacokinetic control parameter. Results Paclitaxel concentrations at the end of infusion did not change significantly from week 1 to week 6. The expression of TP in peripheral mononuclear blood cells decreased significantly after infusion below pretherapeutic values (p = 0.023; n = 8). After the nadir on day 3, the expression of TP increased moderately returning to baseline levels within one week. The overall picture in week 6 was similar to week 1. Using a trend analysis, neither a short-term nor a long-term induction of TP was observed. Conclusion TP in peripheral mononuclear blood cells was hardly regulated under therapy with paclitaxel. Therefore, no increased haematotoxicity due to TP upregulation is expected from the combination of taxanes and capecitabine.

Abstract
Docetaxel is a semisynthetic taxane, a class of anticancer agents that bind to beta tubulin, thereby stabilising microtubules and inducing cell-cycle arrest and apoptosis. Docetaxel was first approved for the treatment of anthracycline-refractory metastatic breast cancer in the mid-1990s. Since then, several randomised trials have reported improved time-to-progression, overall survival, or both in metastatic breast cancer treated with single-agent docetaxel or docetaxel-based combination regimens. Data from two adjuvant trials have shown a survival benefit with the addition of docetaxel to standard anthracycline-based regimens in patients with high-risk early breast cancer. In four randomised studies, docetaxel improved survival in locally advanced or metastatic non-small-cell lung cancer. Moreover, two trials have shown that docetaxel combined with estramustine or corticosteroids improves survival in metastatic androgen-independent prostate cancer. Here, we review major randomised phase III trials with docetaxel in the treatment of solid malignant disease.

Abstract
Thymidine phosphorylase (TP), an enzyme involved in pyrimidine metabolism, is identical with an angiogenic factor, platelet-derived endothelial cell growth factor (PD-ECGF). TP is overexpressed in various tumors and plays an important role in angiogenesis, tumor growth, invasion and metastasis. The enzymatic activity of TP is required for the angiogenic effect of TP. A novel, specific TP inhibitor, TPI, inhibits angiogenesis induced by overexpression of TP in KB/TP cells (human KB epidermoid carcinoma cells transfected with TP cDNA), as well as the growth and metastasis of KB/TP cells in vivo. 2-deoxy-D-ribose, the degradation product of thymidine generated by TP activity, has both angiogenic and chemotactic activity. Both 2-deoxy-D-ribose and TP inhibit a hypoxia-induced apoptotic pathway. These findings suggest that 2-deoxy-D-ribose is a downstream mediator of TP function. 2-deoxy-L-ribose, a stereoisomer of 2-deoxy-D-ribose, inhibits the promotion of angiogenesis, tumor growth and metastasis by TP. Although the mechanism of the action of 2-deoxy-D-ribose is still unknown, 2-deoxy-L-ribose may inhibit the physiological activities of 2-deoxy-D-ribose, and consequently those of TP. Inhibition of TP activity and function appears to be a promising approach for the chemotherapy of various tumors.

Abstract
We have evaluated the efficacy and safety of the combination of capecitabine and vinorelbine in metastatic breast cancer (MBC) patients previously treated with anthracycline-and taxane-containing regimens. Between April 2000 and September 2002, 44 female MBC patients received oral capecitabine (1,250 mg/m2 twice daily on days 114), and intravenous vinorelbine (25 mg/m2 on days 1 and 8) during each 3 week-chemotherapy cycle (median, 5 cycles/patient; total, 235 cycles). One patient achieved a complete response and 21 patients had partial responses, giving an overall response rate of 50% in the intention-to-treat analysis (95% CI, 35.0-65.0%). Median duration of response was 6.0 months (range 1.2-23.0 months). Patients were followed- up for a median of 16 months, with median progression-free survival being 5.3 months, and median overall survival being 17 months. Toxicities included grades III and IV neutropenia in 63 (26.8%) and 4 (1.7%) cycles, respectively, and grades II and III hand-foot syndrome in 12 (5.1%) and 4 (1.7%) cycles, respectively. Other nonhematologic toxicities were minimal and manageable. In conclusion, the combination of capecitabine and vinorelbine was effective and well tolerated in MBC patients even after treatment with anthracyclines and taxanes.

Abstract
The rationale for weekly administration of paclitaxel, which acts on microtubules to arrest mitosis, is that more frequent delivery of moderate doses may achieve greater efficacy than standard doses every 3 weeks, through more sustained exposure of dividing tumor cells to its cytotoxic effects. This dose-dense approach to treatment may inhibit tumor regrowth between cycles and limit the emergence of malignant cell populations resistant to chemotherapy. More frequent exposure to paclitaxel may also enhance its apoptotic and antiangiogenic effects. Paclitaxel activity is considered to be independent of p53 status, in contrast to anticancer drugs that produce lesions on DNA, which achieve a better response if p53 is functional. Weekly therapy also has advantages in terms of improving paclitaxel therapeutic index. Clinical studies show that weekly paclitaxel is effective and that toxicity is acceptable. The response rates of single-agent paclitaxel varied from 21 to 86% in breast cancer, from 20% to 65% in ovarian cancer and from 30% to 56% in non-small cell lung cancer.
