This study is an open-label, multi-center, dose-escalation, dose-finding and expansion study in adult subjects with advanced solid tumors for whom no standard therapy is available. The study will evaluate the safety, tolerability, PK, PD, and preliminary anti-tumor efficacy of SM08502 administered orally, once daily, following a 28-day treatment cycle (Part 1A). Alternative dosing schedules will be explored in Part 1B and the recommended Part 2 dose and schedule will be further evaluated in Part 2.
Subjects will participate in a screening period of up to 14 days. Dosing in 28-day cycles will continue within each subject, unless treatment is discontinued due to toxicity, disease progression, initiation of a new anti-neoplastic therapy, withdrawal of consent, the Sponsor terminates the study, or the subject no longer meets retreatment criteria.
Approximately 10 subjects enrolled in Part 2, irrespective of the tumor type, will be included in a food effect substudy to assess the preliminary effect of a high-fat, high-calorie meal on the PK of SM08502. Subjects participating in the food effect substudy will continue on study and complete assessments as per the Part 2 schedule and receive SM08502 at the recommended Part 2 dose (or another previously assessed dose level and schedule).

Open to people ages 18 years and up
- Subjects with advanced solid tumors (as defined below):
- Part 1A - Subjects with advanced solid tumors who are refractory to or intolerant of established therapy known to provide clinical benefit for their condition (i.e., subjects must not be candidates for regimens known to provide clinical benefit) and for which histologic or cytologic confirmation of malignancy was obtained at diagnosis, with the exception of hepatocellular carcinoma if it meets appropriate imaging-only diagnostic criteria (per the National Comprehensive Cancer Network [NCCN], Liver Imaging Reporting and Data System [LI-RADS], American Association for the Study of Liver Diseases [AASLD], Asian Pacific Association for the Study of the Liver [APASL], or European Association for the Study of the Liver - European Organisation for Research and Treatment of Cancer [EASL-EORTC]).
- Part 1B - Subjects with advanced and/or metastatic solid tumors who are refractory to or intolerant of established therapy known to provide clinical benefit for their condition (i.e., subjects must not be candidates for regimens known to provide clinical benefit in the Investigator's judgment). Histologic or cytologic confirmation of malignancy must have been obtained at diagnosis. The tumor types include: i. NSCLC (adenocarcinoma subtype) ii. TNBC iii. CRPC iv. CRC
- Endometrial cancer (endometrioid subtype) vi. Ovarian cancer (serous, mucinous, and endometrioid subtypes).
- Part 2 - Subjects with advanced and/or metastatic solid tumors who are refractory to or intolerant of established therapy known to provide clinical benefit for their condition. Histologic or cytologic confirmation of malignancy must have been obtained at diagnosis. Subjects must have received no more than 2 prior lines of myelosuppressive chemotherapy. Additionally, CRPC subjects must have received no more than 4 total lines of treatment (including any hormonal therapies) in any setting. The tumor types include: i. NSCLC (adenocarcinoma subtype) ii. CRPC in two biomarker selected cohorts.
- Measurable or evaluable disease per RECIST 1.1 (Part 1A). For Parts 1B and 2, at least 1 measurable lesion per RECIST 1.1 that has not been previously irradiated. In CRPC subjects (Parts 1B and 2) without measurable disease per RECIST 1.1, a PSA that is concordant with clinical disease progression (rising) is eligible. A PSA value of 2 ng/ml or greater is required for study entry.
- Subjects must have archived tumor specimens available for analysis (as specified in Section 7.2.2). Otherwise, a fresh tumor biopsy will be required at study entry. At the discretion of the Sponsor's Medical Monitor, a fresh tumor biopsy may not be required for eligibility if there are extenuating circumstances (e.g., inaccessible sites of disease or lack of subject suitability to undergo a fresh biopsy, or molecular profiling of archived tissue already performed).
- Subjects must have recovered (i.e., Grade 1 [or better] based on CTCAE v5.0) from all toxicity associated with previous chemotherapy, targeted therapy, experimental therapy, biological therapy, immuno-oncology therapy, surgery, radiotherapy, or other locoregional therapy (Exceptions include subjects with: continuing alopecia regardless of any CTCAE grade, Grade 2 or lower neuropathy, and well-controlled hypothyroidism and/or adrenal insufficiency on chronic hormone replacement. All subjects with these exceptions are eligible).
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1.

degeneration, other forms of retinal degenerative disease, or other retinal findings that may place the subject at risk
