Phase I/II Study of a Triplet Combination of CBP501, Pemetrexed and Cisplatin in Patients With Advanced Solid Tumors and in Chemotherapy-naïve Patients With Malignant Pleural Mesothelioma
In Brief
A Phase 2 clinical trial evaluating pemetrexed, cisplatin and CBP501, pemetrexed and cisplatin, and 1 other intervention for Malignant Pleural Mesothelioma and Solid Tumors. Completed, enrolled 69 participants across 12 sites.
Detailed Summary
The phase I part of the study is a dose-finding study of escalating doses of CBP501 combined with full-dose cisplatin and pemetrexed in patients with histologically confirmed solid malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective or would otherwise be eligible for cisplatin and pemetrexed as first-line therapy. The maximum tolerated dose (MTD) will be determined based on DLTs occurring during the first treatment cycle. Pharmacokinetics of the triplet combination will be assessed during the phase I part of the trial. The phase II part will evaluate full-dose cisplatin and pemetrexed combined with CBP501 (at the MTD determined in the phase I part) in previously untreated, unresectable malignant pleural mesothelioma patients. Patients will be randomized in a 2 : 1 ratio to pemetrexed, cisplatin and CBP501 (Arm A) or to pemetrexed and cisplatin (Arm B); randomization will be stratified according to histology and performance status.

Interventions
CBP501 25 mg/m2, Pemetrexed 500 mg/m2, cisplatin 75 mg/m2 CBP501 for injection is provided in single dose vials (20 mg) containing a sterile lyophilized powder comprising CBP501 peptide acetate salt (peptide base units). For administration, vial contents are reconstituted in 5% Dextrose Injection, USP, and added to a 100 mL IV bag of 5% Dextrose Injection, USP. Pemetrexed: A commercial formulation of pemetrexed will be used, with reconstitution in 20mL 0.9% sodium chloride solution for injection, then dilution to 100mL. Cisplatin: A commercial formulation will be used and will be diluted in 250 mL of normal saline for administration.
Pemetrexed 500 mg/m2, cisplatin 75 mg/m2 Pemetrexed: A commercial formulation of pemetrexed will be used, with reconstitution in 20mL 0.9% sodium chloride solution for injection, then dilution to 100mL. Cisplatin: A commercial formulation will be used and will be diluted in 250 mL of normal saline for administration.
