- Statistically significant improvement in median rPFS was 10.3 months in the treatment arm compared to 4.1 months in the placebo arm ( p = 0.011)
- Median Overall Survival (OS) has not yet been reached
- Patients tolerated therapy with indoximod with no significant differences in adverse events between the two arms
- There was no statistical difference in the primary endpoint of ELISPOT assay immune response to PA2024, the PROVENGE-related fusion protein, in the 35 of 46 patients who had clinical samples available for testing
Navoximod in combination with TECENTRIQ ® ( atezolizumab) in multiple solid tumorsInitial data from a Phase 1b dose-escalation study of navoximod in combination with TECENTRIQ ® for patients with locally advanced or metastatic solid tumors conducted by our partner, Genentech/Roche, will be presented in an oral presentation (Abstract number 105) by Howard A. "Skip" Burris, III, M.D., President Clinical Operations and Chief Medical Officer, Sarah Cannon Research Institute, at ASCO in Chicago on Sunday, June 4, 2017, 10:24 a.m. CT. The presentation is titled, A phase 1b dose-escalation study of combined inhibition of IDO1 (GDC-0919) and PD-L1 (atezolizumab) in patients with locally advanced or metastatic solid tumors. This Phase 1b, open-label, dose-escalation study is designed to characterize safety and tolerability. Secondary objectives include identifying a maximum tolerated dose (MTD) and recommended Phase 2 dose, and evaluating pharmacokinetics, pharmacodynamics, and anti-tumor activity. Patients were given TECENTRIQ (1200 mg IV every 3 weeks) and escalating doses of navoximod (orally twice daily, for 21 days) using a standard 3+3 design. Initial results from this study (n=52, non-selected heterogeneous population during the dose escalation) found the combination was generally well-tolerated, with peripheral IDO1 modulation, and some early activity signals. Patients were previously treated with prior systemic therapies with a median number of 3 and a range of 1-9. Two patients also received prior immunotherapy. The design of the trial includes the initial dose-escalation phase reported in this abstract, followed by disease-specific expansion cohorts (enrollment target is 305 patients) for patients with select tumor types including non-small-cell lung cancer (NSCLC), renal cell cancer (RCC), urothelial bladder cancer (UBC), triple negative breast cancer (TNBC), to further evaluate safety, response, and peripheral and tumor pharmacodynamics. Updates for this study will continue to be reported by Genentech/Roche. Dr. Vahanian continued, "We are encouraged by the clinical profile for the combination of navoximod and atezolizumab from the first phase of this combination trial and look forward to the data for the disease-specific expansion cohorts which are currently accruing patients."
