362P - Phase Ia study to evaluate GDC-6036 monotherapy in patients with colorectal cancer (CRC) with KRAS G12C mutation
- Jayesh Desai (Melbourne, Australia)
Abstract
Background
The oncogenic
Methods
As part of an ongoing phase I dose-escalation/expansion study (NCT04449874), pts with advanced and metastatic
Results
As of 28 Jan 2022, 43 pts with CRC were enrolled (n, 50 mg: 2; 100 mg: 7; 200 mg: 4; 400 mg: 30). Median (range) number of prior cancer therapies was 3 (1-7). No dose-limiting toxicities were reported across all solid tumors. Median (range) time on study treatment was 2.8 (0.1-11.2) months among pts with CRC and median GDC-6036 dose intensity was 100%. Sixteen (37%) pts discontinued study treatment (13 due to RECIST progression, 2 due to symptomatic deterioration, 1 patient withdrawal). The most frequent GDC-6036-related AEs (≥ 10% pts) were nausea, diarrhea, vomiting, dyspepsia, fatigue, and decreased appetite; the only Grade ≥3 AE was diarrhea (3 pts, 7%; all Grade 3). AEs were manageable with supportive measures. Five (12%) pts required a dose modification (interruption [4 pts] or reduction [1 pt]; no withdrawal) for GDC-6036-related AEs. Across all solid tumor patients, the mean half-life for GDC-6036 ranged from 13-17 hours at doses of 50-400 mg. The unconfirmed overall response rate (ORR) in pts with CRC was 29% (12/41 pts with measurable disease; 1 complete response), while the confirmed ORR was 20% (8/41 pts) across dose levels in this ongoing study. Among responders, a decrease in ctDNA levels was observed as early as C1D15.
