JAB-8263 is a small-molecule inhibitor of the highly conserved bromodomain pockets of the bromodomain and extraterminal (BET) proteins.

The objectives of this study are:

To determine the maximum-tolerated dose (MTD) and assess the dose-limiting toxicity (DLT) of JAB-8263 as a single agent to adult subjects with advanced solid tumors To assess the safety and tolerability of JAB-8263 To characterize the pharmacokinetic (PK) parameters and pharmacodynamics (PDc) To evaluate preliminary antitumor activity of JAB-8263.

Inclusion Criteria:

Subjects must meet all the following criteria in order to be included in the research study:

Subject must be ≥18 years-of-age at the time of signature of the informed consent form (ICF).
Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1.
Subjects with histologically or cytologically confirmed advanced solid tumors which have progressed despite standard therapy(ies), or are intolerant to standard therapy(ies), or have a tumor for which no standard therapy(ies) exists.
Patients must have at least one measurable lesion as defined by RECIST v1.1.
