Arms and Interventions

Arm	Intervention/Treatment
Experimental: Part 1: Dose Escalation, Food effect and Relative Bioavailability of Capsule formulation to Tablet Participants will receive escalating doses of GSK3326595 until the maximum tolerated dose level is reached. The recommended phase 2 dose (RP2D) will be determined. Participants will be dosed in a fed (high-fat, high-calorie meal) and fasted state to determine the effect of food on bioavailability of GSK3326595, and will be dosed with tablet and capsule to compare two formulations of GSK3326595 (capsule versus tablet).	Drug: GSK3326595 GSK3326595 will be administered with and without food, in tablet and capsule formulation.
Experimental: Part 2: Disease-Specific Expansion cohort Participants with triple-negative breast cancer (TNBC), metastatic transitional cell carcinoma of the urinary system (mTCC), Grade IV anaplastic astrocytoma (glioblastoma multiforme [GBM]), non-Hodgkin's lymphoma (NHL), adenoid cystic carcinoma (ACC), hormone receptor-positive adenocarcinoma of the breast (ER+BC), human papillomavirus (HPV)-positive solid tumors of any histology, and p53-wild type non-small cell lung cancer (NSCLC) will be administered GSK3326595 at the recommended phase 2 dose (RP2D) as determined in Part 1.
