Phase I study of enzastaurin and bevacizumab in patients with advanced cancer: safety, efficacy and pharmacokinetics.

ABSTRACT:

Purpose

Given distinct mechanism of actions of enzastaurin and bevacizumab, preclinical studies suggest enhanced antitumor activity in combination. This phase I study assessed the combination's safety and efficacy.

Patients and methods

Six advanced cancer patients could be enrolled in each of 11 cohorts. Patients received an enzastaurin loading dose. Oral enzastaurin (500 mg once daily [QD], 250 mg twice daily [BID], 375 mg BID, 500 mg BID, and 750 mg BID) was escalated in each cohort in combination with bevacizumab dosed at 5 mg/kg every 2 weeks, 10 mg/kg every 2 weeks, or 15 mg/kg every 3 weeks until a dose-limiting toxicity (DLT) occurred in 2 of 6 patients in any cohort.

Results

Sixty-seven patients (31, ovarian cancer [ovcar]) were evaluable for safety and efficacy. Six treatment-related DLTs occurred: grade 3 fatigue (n=4), grade 4 cerebral hemorrhage, and grade 3 elevated aspartate transaminase. Common drug-related toxicities included change in color of urine and stool, fatigue, pain, diarrhea, and nausea. The maximum tolerated dose of enzastaurin was 750 mg BID in combination with any tested bevacizumab dose/schedule. Overall response rate was 19.4 % (32.3 % ovcar). Median time to progression was 3.7 months (95 % confidence interval [CI], 2.7-5.5), with 8.3 months (95 % CI, 3.7-11.1) in ovcar. Overall, 35.9 % (50.4 % ovcar) of patients remained without disease progression after 6 months.

Conclusion

The recommended phase II doses of enzastaurin were 500 mg QD up to 500 mg BID with any tested dose/schedule of bevacizumab. This combination demonstrated encouraging clinical activity, particularly in ovcar.

Project description:BackgroundMB02 (bevacizumab biosimilar) showed similar structural, functional, and pharmacokinetic properties to reference bevacizumab (Avastin®; EU-bevacizumab).ObjectivesTo confirm clinical similarity between MB02 and EU-bevacizumab, a comparability study was undertaken in the first-line treatment of stage IIIB/IV non-squamous non-small cell lung cancer (NSCLC).Patients and methodsThis multinational, double-blind, randomized, phase III study (STELLA) compared MB02 or EU-bevacizumab (15 mg/kg) administered with chemotherapy (paclitaxel 200 mg/m2 and carboplatin AUC6) on Day 1 of every 3-week cycle for 6 cycles (Week 18), followed by MB02/EU-bevacizumab in blinded monotherapy until disease progression, unacceptable toxicity, death, withdrawal of consent or end of study (Week 52). The primary efficacy endpoint was objective response rate (ORR) evaluated by an independent radiological review committee (IRC) at Week 18 (intent-to-treat population). Secondary endpoints included progression-free survival (PFS), overall survival (OS), safety and immunogenicity.ResultsA total of 627 subjects were randomized 1:1 to MB02 (n = 315) or EU-bevacizumab (n = 312). ORR, assessed by the IRC at Week 18, was comparable in MB02 (40.3%) and EU-bevacizumab (44.6%) groups. ORR risk ratio of 0.910 (90% CI 0.780 to 1.060; 95% CI 0.758 to 1.092) and ORR risk difference of -4.02 (90% CI -10.51 to 2.47; 95% CI -11.76 to 3.71) were within the similarity predefined margins. There were no significant differences between MB02 and EU-bevacizumab groups in median PFS (36.0 vs 37.3 weeks, respectively; HR 1.187; 95% CI 0.98 to 1.44) and median OS (not achieved; HR 1.108; 95% CI: 0.83 to 1.49) at the end of study. The safety profile of MB02 and EU-bevacizumab regarding nature, frequency and severity of the adverse events (AE) was comparable. The most frequent grade ≥3 investigational-product-related AEs were hypertension and anemia, with a difference between treatment groups of <5%. Anti-drug antibodies (ADA) and neutralizing ADA (NAb) incidence were similar in both treatment groups.ConclusionMB02 demonstrated similar efficacy to EU-bevacizumab, in combination with carboplatin and paclitaxel, in subjects with advanced non-squamous NSCLC, with comparable safety and immunogenicity profiles.Clinical trial registrationEudraCT No. 2017-001769-26; ClinicalTrials.gov: NCT03296163.

Project description:Background:Nintedanib is an oral, triple angiokinase inhibitor of vascular endothelial growth factor/platelet-derived growth factor/fibroblast growth factor receptors. This randomized, multicenter, open-label, phase I/II study evaluated the safety, pharmacokinetics, maximum tolerated dose (MTD) in terms of dose-limiting toxicities (DLTs), and efficacy of nintedanib versus sorafenib in Asian patients with unresectable advanced hepatocellular carcinoma (HCC). Patients and Methods:For the phase I portion, patients were stratified into two groups according to their alanine aminotransferase/aspartate aminotransferase (ALT/AST) and Child-Pugh score at baseline. For phase I, the primary endpoint was determination of the MTD in terms of DLTs. For phase II, patients with a Child-Pugh score of 5-6, an Eastern Cooperative Oncology Group performance score ?2, and an ALT/AST ?2× the upper limit of normal were enrolled and randomized 2: 1 to nintedanib 200 mg twice daily (b.i.d.) (the MTD determined in phase I) or sorafenib 400 mg b.i.d. continuously in 28-day cycles until intolerable adverse events (AEs) or disease progression (PD); treatment beyond PD was allowed if clinical benefit was perceived. The primary endpoint for phase II was time to progression (TTP) by central independent review (CIR; by Response Evaluation Criteria in Solid Tumors v1.0); the secondary endpoints included overall survival (OS). All analyses were exploratory. Results:The MTD was 200 mg in both groups. For phase II, 95 patients were randomized to nintedanib (n = 63) or sorafenib (n = 32). For nintedanib and sorafenib, respectively, the median CIR TTP was 2.8 vs. 3.7 months (hazard ratio [HR] = 1.21, 95% confidence interval [CI] 0.73-2.01) and the median OS 10.2 vs. 10.7 months (HR = 0.94, 95% CI 0.59-1.49). Nintedanib-treated patients had fewer grade 3 or higher AEs (56 vs. 84%), serious AEs (46 vs. 56%), and AEs leading to dose reduction (19 vs. 59%) and drug discontinuation (24 vs. 34%). AEs associated more frequently with nintedanib were vomiting and nausea, whereas those associated more frequently with sorafenib were ALT/AST increases, diarrhea, rash, and palmar-plantar erythrodysesthesia syndrome. Conclusions:Nintedanib showed numerically similar efficacy to sorafenib for CIR TTP and OS in Asian patients with advanced HCC and adequate liver function. AEs were generally manageable.
