Abstract 2130

Background

The PD-1/PD-L1 pathway is a key regulator of T-cell activation and a promising target for cancer treatment. MEDI0680 (M) is a humanized IgG4κ mAb specific for human PD-1 that blocks interaction with PD-L1 and programmed cell death ligand-2 (PD-L2). Durvalumab (D; MEDI4736) is a selective, high-affinity, engineered human IgG1 mAb that blocks PD-L1 binding to PD-1 and CD80. Blocking both the PD-1 receptor and its ligand by combining M + D offers the potential for complete PD-1/PD-L1 axis inhibition.

Methods

This ongoing Phase 1 open-label, dose-escalation and expansion study is evaluating M + D in patients (pts) ≥18 years with relapsed/refractory advanced solid malignancies and ECOG performance status 0-1 (NCT02118337). The primary objectives are safety and maximum tolerated dose (MTD). Secondary objectives include antitumor activity.

Results

As of 2 November 2015, 30 pts across various histologies were treated in 6 dose cohorts (Table) with 50% remaining on study. 1 dose-limiting toxicity occurred (Cohort 5; Grade 3 elevated AST/ALT). The MTD has not been reached. The most common drug-related AEs were pruritus (17%); diarrhea and fatigue (both 13%); and flushing, peripheral edema, and pyrexia (each 10%). Immune-related AEs were similar to those seen with other checkpoint blockade agents. No drug-related AEs led to death. 2 pts (7%) discontinued due to drug-related AEs. Of 26 evaluable pts, 1 had a complete response (CR; Cohort 5; bladder cancer), 3 had a partial response (PR) and 9 had stable disease (SD). Increased Ki67+ (proliferating) CD4+ and CD8+ T cells and elevated circulating IFNɣ, CXCL9, CXCL10, and CXCL11 levels were observed with M + D, indicating pharmacodynamic activity of PD-1/PD-L1 pathway blockade. Updated clinical data will be presented.

*Response evaluable population

Conclusions

M 10 mg/kg + D 10 mg/kg Q2W appears to be well-tolerated and active in this population.
