Study With Andes-1537 in Patients With Specific Types of Advanced Solid Tumor

Colorectal Cancer Clinical Trial

Official title: Phase 1 Open-label Two-stage Safety and Tolerability Study With Subcutaneous Administration of Andes-1537 for Injection in Patients With Specific Types of Advanced Solid Tumors That Are Refractory To or No Available Standard Therapy

Status Completed

Clinical Trial Summary

The study is a Phase 1 Open-label Two-stage, Safety and Tolerability Study with Cancer Type-specific Cohorts, Evaluating Subcutaneous Administration of Andes-1537 for Injection in Patients with Advanced Solid Tumors that are Refractory to Standard Therapy or For Which No Standard Therapy Is Available. Patients with unresectable solid tumors that are refractory or have failed standard therapy and are deemed non-eligible or intolerant to further therapy or for which no standard therapy is available will be included in 5 cancer type-specific parallel cohorts. The following tumor types will be evaluated for potential inclusion in each cancer type-specific cohort: gallbladder & biliary tract carcinoma; cervical carcinoma; gastric carcinoma; pancreatic carcinoma, and colorectal carcinoma.

Clinical Trial Description

After screening, 9 patients in each cancer type-specific cohort (gallbladder & biliary tract carcinoma; cervical carcinoma; gastric carcinoma; pancreatic carcinoma, and colorectal carcinoma) will enter stage 1. These patients will receive a dose of 400 mg of Andes-1537 five times per week for continuous cycles of 4 weeks that will be repeated until the patients presents drug toxicity requiring treatment discontinuation or disease progression with no noted clinical benefit as assessed by the investigator. The safety and tolerability evaluation will be continuous during the study. The efficacy evaluation will be done by analysis of the clinical objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria after patients complete the first two cycles (8 weeks). Thereafter, clinical ORR will be assessed every 8 weeks. Additionally, tumor-cell activity assessment will be performed in biopsy samples after the patients complete the first 2 cycles (8 weeks). Tumor markers assessment according to the type of tumor will be evaluated every 2 cycles and at the end of study (EOS) visit. Analysis of the tumor metabolic activity through the PET-CT scan and quality of life of patients through questionnaire will be evaluated every 2 cycles. As predefined and according with the decision of the Study Safety and Steering Committee (SSC), in those cohorts where minimal clinical response criteria were met or according to the decision of the SSC based on the risk / benefit analysis, considering toxicity criteria and observed biological responses, 15 additional patients will be recruited (total of 24 patients per cohort) for stage 2 of the study. Patients included in stage 2 will receive the same treatment regimen described for stage 1 and will be followed until the patients present disease progression or drug toxicity requiring treatment discontinuation. Patients included in stage 2 will receive the same follow-up as patients in stage 1. ;
