Brief Summary

Study Design and Investigational Plan:

This is an open-label Phase 1/2 study to assess the safety and tolerability of combination PD-1 inhibitor (APL-501 or nivolumab) administered concomitantly with c-Met inhibitor (APL-101), to determine the recommended Phase 2 dose of the combination, and to obtain preliminary efficacy in HCC or RCC subjects with advanced or metastatic disease that have not been previously treated with a PD 1 inhibitor or a c-Met inhibitor. HCC subjects will receive the combination APL-501 plus APL-101 while RCC subjects will receive the combination nivolumab plus APL-101. In Phase 1, mandatory archival or fresh tumor biopsies will be collected. In Phase 2, a mandatory fresh tumor biopsy will be required for study entry and another fresh biopsy will be collected between Cycles 2 and 4. The frequency of administration of PD-1 inhibitors will be every 2 weeks starting in Cycle 1 on Day 8 and Day 22 of a 35-day cycle with all subsequent cycles on Day 1 and Day 15 of 28-day cycles. APL-101 will be administered orally every 12 hours continuously on an empty stomach.

Detailed Description

For each potential subject, there is a 28-day screening and eligibility assessment period before enrollment; the first dose of study treatment will be administered on Day 1 of Cycle 1 (C1D1) (Safety population). Subjects will continue to receive their assigned treatment throughout the study until the occurrence of confirmed disease progression [progressive disease (PD)] by irRECIST, death, unacceptable treatment-related toxicity, or until the study is closed by the Sponsor. During the treatment period, study visits will occur on Day 1, Day 2, Day 8, Day 15, Day 22 of Cycle 1 and Day 1 and Day 15 of every subsequent cycle. Subjects who experience a response [Complete Response (CR), Partial Response (PR)] ≥ 2 cycles, PD 1 plus APL-101 combination will be continued until disease progression based on irRECIST. Subjects should receive a minimal of 2 cycles of PD-1 and APL-101 for adequate evaluation of response (Evaluable population). Discontinuation of PD-1 and APL-101 should occur upon determination of disease progression as determined by irRECIST, intolerable toxicity or when the risk/benefit ratio is no longer beneficial for the subjects as determined by the Principal Investigator, or upon subject withdrawal of consent. Upon permanent discontinuation of study treatment, there is a Treatment Termination visit and three monthly follow-up visits for a 90-day safety follow-up visit period. Subjects who drop out before they complete the first cycle of combination treatment for reasons other than toxicity will be replaced

Eligibility Criteria

Inclusion Criteria

1. Able to understand and comply with the study procedures, understand the risks involved in the study, and provide written informed consent.

2. Men and women 18 years of age or older.

3. Histologically confirmed advanced or metastatic hepatocellular carcinoma that progressed while receiving at least one previous line of systemic therapy, including sorafenib, or who are intolerant of or refused sorafenib treatment following progression on standard therapy including surgical and/or local regional therapies, or standard therapy considered ineffective, intolerable, or inappropriate or for which no effective standard therapy is available.

4. Histologically confirmed advanced or metastatic renal cell carcinoma with clear cell component who received one or two prior lines of antiangiogenic therapy in addition to no more than three previous regimens of systemic therapy including cytokines and cytotoxic chemotherapy agents.

5. Disease according to irRECIST that can be reliably and consistently followed.

6. Documented disease progression during or after the last treatment regimen and within 6 months before study enrollment.

7. Tumor amenable to tumor biopsy and subject agreeable to tumor biopsy at study entry and during therapy with study treatment.

8. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.

9. Acceptable organ function.

Exclusion Criteria

1. History of severe hypersensitivity to mAbs, excipients of the APL-501, nivolumab, or APL-101.

2. History of receiving treatment with any c-Met signaling pathway inhibitor (marketed or investigational agents).

3. Prior therapy with anti-PD-1, anti-PD-L1, anti-PDL-2, or anti-CTLA-4 antibody (or any other antibody targeting T cell co-stimulation pathways).

4. Unwilling to swallow orally administered medication whole.

5. Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter drug absorption (e.g., Crohn's, ulcerative colitis, active inflammatory bowel disease, uncontrolled nausea, vomiting, diarrhea, or malabsorption syndrome).
