Brief summary
A Phase 1, Drug-Drug Interaction Study to Evaluate the Safety, Tolerability, and the Induction Potential of TBAJ-876 on CYP3A4 and P-glycoprotein and the Inhibition Potential of TBAJ-876 on P-glycoprotein in Healthy Adult Subjects
Detailed description
This study was a two-part, open-label drug-drug interaction study conducted in one study center in the United States. Two groups were planned, Group 1 and Group 2. Group 2 to be conducted based on the Group 1 results. Group 1 to assess the induction potential of TBAJ-876 on the sensitive CYP3A4 substrate midazolam (M) and inhibition and induction potential of TBAJ-876 on the sensitive P-glycoprotein substrate Digoxin (D). Group 2 was only to be conducted if the results of Group 1 show that TBAJ-876 is a moderate inducer of either CYP3A4 (geometric mean ratio \[GMR\] of midazolam area under the curve \[AUC\] \<0.50 when co-administered with TBAJ-876) or P-glycoprotein (GMR of digoxin AUC \<0.50 when co-administered with TBAJ-876) or a moderate inhibitor of P-glycoprotein (GMR of digoxin AUC ≥2.0 when co-administered with TBAJ-876). These results were used to decide that a second phase of the study was not needed. If Group 1 concluded that TBAJ-876 is a moderate inducer or inhibitor, Group 2 had intended to quantify the magnitude of inhibition or induction of TBAJ-876 of the antiretroviral regimen TLD, a fixed dose combination of tenofovir disoproxil fumarate (TFD), lamivudine (3TC) and dolutegravir (DTG), a regimen likely to be used in future clinical studies of TBAJ-876 by subjects living with HIV Safety was assessed throughout the study for all subjects. Safety assessments included physical examinations, vital signs, serial ECGs, adverse events (AEs), clinical and laboratory tests (including hematology, serum chemistry, coagulation, and urinalysis).

Geometric mean ratio of midazolam's area under the (plasma concentration vs. time) curve and Cmax when co-administered with TBAJ-876 versus when administered alone. Inference will be based on analysis of variance applied to log-transformed parameters.

Number of Participants With Treatment-Related Adverse Events (TEAE) in Group 1 Population
Participants will be monitored for any adverse events from the signing of the consent form until the end-of-study visit. The Investigator or a Sub-Investigator will assess its relationship to the study drug. Note about ST segment elevation which was reported as a treatment-related adverse event. Upon review of the screening ECG, early repolarization was noted and therefore the ST segment elevation was considered pre-existing and not a TEAE however the AE remained in the database instead of being removed.
