Clinical Trial Summary

This is a first-in-human, Phase 1/2 multi-center, open-label, dose escalation and expansion study of AO-176 which will evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and clinical effects of AO-176 in patients with advanced solid tumors.


Clinical Trial Description

This is a first-in-human, Phase 1/2 multicenter, open-label, dose escalation and expansion study of AO-176 in patients with solid tumors. Part A of this study will examine escalating repeat doses of AO-176 monotherapy in patients with select advanced solid tumors, including epithelial ovarian carcinoma (EOC), which will include primary peritoneal and fallopian tube carcinoma; squamous cell carcinoma of the head and neck; endometrial carcinoma; castration resistant prostate cancer; non-small cell lung adenocarcinoma; papillary thyroid carcinoma; pleural or peritoneal malignant mesothelioma; and gastroesophageal adenocarcinoma, for which standard therapy proven to provide clinical benefit does not exist or is no longer effective. Part B and Part C of this study will examine escalating repeat doses of AO-176 in combination with paclitaxel (Part B) or pembrolizumab (Part C) in platinum-resistant EOC, including primary peritoneal and fallopian tube carcinoma; endometrial carcinoma; and gastric adenocarcinoma/gastroesophageal adenocarcinoma. The monotherapy and combination dose escalation portions of the study utilize a classic 3+3 design, with enrollment of 3 patients per cohort and expansion of the cohort in the event of a dose-limiting toxicity (DLT). Once the maximum-tolerated dose (MTD)/recommended phase 2 dose (RP2D) has been established in dose escalation, tumor-specific dose expansion cohorts will be recruited to further assess safety and evaluate preliminary efficacy of AO-176 as monotherapy, in combination with paclitaxel, and in combination with pembrolizumab. ;
