Phase II Study of CAP-232 in Patients With Refractory Metastatic Renal Cell Carcinoma

Thallion Pharmaceuticals10 enrolled

Overview

The purpose of this study was to evaluate the safety and efficacy of CAP-232 in the treatment of patients with previously treated (refractory) renal cell carcinoma

This was a multi-center, open label, single arm study. Approximately 40 patients were initially planned to be recruited. Each patient was to receive a treatment cycle consisting of CAP-232 via continuous IV infusion over 21 days at 0.48 mg/kg/day followed by a 7-day rest period. Treatment cycles to be repeated in the absence of disease progression or unacceptable toxicity. Quality of Life questionnaires were to be administered at baseline, after each visit and at the end of the study. Signs and symptoms of adverse events were closely monitored during treatment cycles. Safety laboratory measures were done at Screening, during the 72hr hospitalization (first cycle), at every interim visit , and at the end of the study. A follow-up safety visit was to be scheduled at least 30 days after the end of treatment. CAP-232 plasma levels were also determined.

Outcomes

Primary Outcomes

The primary efficacy parameter was the response rate based on RECIST criteria after 3 cycles

Secondary Outcomes

Safety (through clinical and biological evaluations)

Other efficacy parameters (progression-free survival rate, time to progression and overall survival)

Pharmacokinetic (PK) characteristics of the first 15 recruited patients

Quality of life

Biological modulation (through potential blood and/or urine biomarkers including M2PK)
