Description of intervention(s) / exposure
Treatment: Drugs - Phase 1b: APG-115+pembrolizumab

Experimental: APG-115+pembrolizumab open label, two-part phase Ib/II - single arm dose escalation and dose expansion


Treatment: Drugs: Phase 1b: APG-115+pembrolizumab
dose escalation of APG-115 in combination with label dose of pembrolizumab, Four dose levels of APG-115 will be tested: 50, 100, 150, and 200 mg. APG-115 will be administrateddose escalation of APG-115 in combination with label dose of pembrolizumab, Fourfour dose levels of APG-115 will be tested: 50, 100, 150, and 200 mg. APG-115 will be administrated orally every other day (QOD) for consecutive 2 weeks (ie. dosed at Day 1, 3, 5, 7, 9, 11, and 13), with one week dosing off as there are cycles every 3-weeks a cycle. Pembrolizumab is administrated following FDA approved label dose, i.e., 200 mg intravenous infusion at Day 1 of every 3 weeks as a cycle.

Phase II: Combination of APG-115 at 150 mg (RP2D) and pembrolizumab or APG-115 monotherapy alone.

4. Cohort F: Histologically confirmed, metastatic or unresectable MPNST
* Life expectancy = 3 months
* Continuance of treatment related toxicities (except alopecia) due to prior radiotherapy or chemotherapy agents or biological therapy (including PD-1/PD-L1 antibodies) must be = grade 1 at the time of dosing
* Adequate bone marrow and organ function without continuous supportive treatment
* QTcF interval (mean of 3, 1-3 minutes between tests) =450 ms in males and =470 ms in females
* Left ventricular ejection fraction (LVEF) = lower limit of institutional normal (LLN) as assessed by echocardiogram (ECHO) or multigated acquisition (MUGA) scan
* Tumor tissue must be provided for all subjects for biomarker analysis before treatment with investigational product
* Willingness to use contraception by a method that is deemed effective by both male and female patients of childbearing potential and their partners throughout the treatment period and for at least three months following the last dose of study drug
* Ability to understand and willingness to sign a written informed consent form.

* Received chemotherapy within 21 days (42 days for nitrosoureas or mitomycin C) prior to first dose
* Part 2 Cohort A: Prior loco-regional treatment with intralesional therapy (e.g., talimogene laherparepvec) for unresectable or metastatic melanoma in the last 6 weeks prior to start of study treatment
* Part 2 Cohort B: Has received radiation therapy to the lung that is >30Gy within 6 months of the first dose of trial treatment
* Part 2 Cohort E: Known FGFR translocation mutation

* Has known active central nervous (CNS) metastases and/or carcinomatous meningitis. Or has neurologic instability per clinical evaluation due to tumor involvement of the CNS.
* Requirement for corticosteroid treatment (with the exception of megestrol and local use of steroid: i.e., topical corticosteroids, inhaled corticosteroids for reactive airway disease, ophthalmic, intraarticular, and intranasal steroids
* Concurrent treatment with an investigational agent or device within 21 days prior to the first dose of therapy
* Failure to recover adequately, as judged by the investigator, from prior surgical procedures.

* Unstable angina, myocardial infarction, or a coronary revascularization procedure within 180 days of study entry
* Active rheumatoid arthritis (RA), active inflammatory bowel disease, chronic infections, or any other disease or condition associated with chronic inflammation

* Has had an allogeneic tissue/solid organ transplant, prior stem cell or bone marrow transplant
* Has previously had a severe hypersensitivity reaction to treatment with another monoclonal antibody (mAb)
* Any other condition or circumstance that would, in the opinion of the investigator, make the patient unsuitable for participation in the study
