Company Profile
Compass Therapeutics is an oncology-focused firm that develops antibody-based therapeutics to treat multiple diseases.
The company's lead product candidate, Tovecimig, is a bispecific antibody that targets delta-like ligand 4 (DLL4) and vascular endothelial growth factor A, which are critical to angiogenesis and tumour vascularisation. It also develops antibodies CTX-471, CTX-8371, and CTX-10726.
Trial Details and Findings
The COMPANION-002 trial is a Phase 2/3 randomised, controlled study of Tovecimig in patients with unresectable advanced, metastatic or recurrent biliary tract cancers who have received one prior systemic chemotherapy regimen.
The study enrolled 168 adult patients, randomised in a 2:1 ratio to receive Tovecimig plus paclitaxel (111 patients) or paclitaxel alone (57 patients).
All patients received 80 mg/m2 Paclitaxel on days 1, 8, and 15 of each 28-day cycle. Patients in the Tovecimig arm were also dosed with 10 mg/kg of Tovecimig on days 1 and 15 of each 28-day cycle.
Earlier in April 2025, Tovecimig, in combination with paclitaxel, achieved an overall response rate (ORR) of 17.1%, including 1 complete response, compared with 5.3% for paclitaxel alone, in patients with biliary tract cancer (BTC) treated in the second-line setting, which was the primary endpoint.
For the secondary endpoint analysis, the trial required a threshold of events in 80% of patients.
