Abstract 4584
Background
ABBV-621, a tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptor agonist, induces cell death in tumor cells by activation of death receptor 4 and 5. Maximum tolerated dose was not reached in dose escalation (Ratain et al. ASCO 2019; NCT03082209). Herein is reported the analysis of safety and antitumor activity in additional pts enrolled in the dose-optimization cohorts with the goal of identifying the recommended phase 2 dose.
Methods
Eligible pts (≥18 years, relapsed/refractory [R/R] KRAS-mutant colorectal [CRC] or pancreatic cancer, ECOG 0–2, measurable disease, willingness to undergo mandatory biopsies) received ABBV-621 intravenously (1.25–7.5 mg/kg) on day (D) 1, D8, and D15 of a 21-D cycle. Analyzed tumor types were evenly distributed across dose levels (DL).
Results
As of 16 Apr 2019, 48 pts received ≥1 dose of ABBV-621 (CRC, n = 24/pancreatic, n = 24; 1.25 mg/kg, n = 8/8; 3.75 mg/kg, n = 8/8; 7.5 mg/kg, n = 8/8). Median age: 63 years (range, 43–76); 65% male, 73% ≥3 prior treatment (Tx) regimens. Median duration of ABBV-621 exposure was 36 days (range, 1–251) with a median 2 Tx cycles (range, 1–12). Tx-emergent and Tx-related AEs are summarized in the table. Ten pts (20.8%) experienced AEs leading to discontinuation; 4 (9.3%) pts had dose-limiting toxicities possibly associated with ABBV-621 administration: respiratory failure (7.5 mg/kg; Grade 5, the only Tx-related death), increased ALT and AST (1.25, 3.75 mg/kg), toxic hepatitis (1.25 mg/kg), non-cardiac chest pain (1.25 mg/kg), and pleuritic pain (1.25 mg/kg). ALT, alanine aminotransferase; AST, aspartate aminotransferase A partial response was observed in 1 pt with CRC (1.25 mg/kg) and 1 pt with pancreatic cancer (3.75 mg/kg). Stable disease at 12 weeks was the best response in 20 pts (41.7%; CRC, n = 9/pancreatic, n = 11).Table:

Conclusions
Administration of ABBV-621 in pts with R/R CRC and pancreatic cancer shows an acceptable safety profile at all DL and evidence of antitumor activity.
