Impairment of gastrointestinal function that may significantly alter the absorption of ZEN003694 or talazoparib 33. Other known active cancer requiring therapy at time of study entry or that progressed or required treatment within 3 years prior to starting study drug (except for skin basal cell carcinoma or squamous cell carcinoma or in situ cervical cancer) 34. History of infection with (screening tests not required): human immunodeficiency virus; hepatitis B virus with currently active disease defined as hepatitis B surface antigen (HBsAg) positivity; or hepatitis C virus unless previously treated and viral load is undetectable except following situations: * HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of enrollment are eligible for this trial. * Patients with a known history of Hepatitis B (defined as Hepatitis B surface antigen \[HBsAg\] reactive) or known active Hepatitis C virus (defined as HCV RNA \[qualitative\] is detected) infection are allowed to be included if: participant on a stable dose of antiviral therapy, HBV viral load below the limit of quantification.
