Study Endpoints

Primary Endpoints

Best Overall Response (BOR) per Investigator
Through Study Completion, Up to Approximately 27 Months

BOR is defined as a subject achieving confirmed complete response (CR) or confirmed partial response (PR) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) as determined by investigators at any time prior to subsequent anticancer therapy.

Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs)
7 day load + 1 cycle (1 cycle is 28 days)

A DLT was defined as the occurrence of any of the following toxicities within the DLT Evaluation Period if judged by the Investigator and Sponsor to be possibly, probably, or definitely related to TTX-030 or budigalimab.

The Incident of Adverse Events
Through study completion, an average of 1 year

Number of study subjects experiencing adverse events (AEs) and serious adverse events (SAEs). Safety profile will be assessed through laboratory evaluations, vital signs, and physical examinations.

Number of Participants Experiencing Study Drug-Related Grade 3 or Higher Adverse Events (AEs)
Up to approximately 24 weeks

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of the study drug as either having a reasonable possibility or no reasonable possibility. AEs are given a grade from 1-5 with Grade 3 being severe but not life-threatening and requiring hospitalization, Grade 4 being life-threatening requiring immediate intervention and Grade 5 being death related to an AE.

Number of Participants With Study Drug-Related Immune-Related Adverse Events (IRAE)

Terminal phase elimination half-life (t1/2)

Number of Participants with Study Drug-Related Adverse Events Grade 3 or Higher
Up to approximately 44 weeks

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of the study drug as either having a reasonable possibility or no reasonable possibility. AEs are given a grade from 1-5 with Grade 3 being severe but not life-threatening and requiring hospitalization, Grade 4 being life-threatening requiring immediate intervention and Grade 5 being death related to an AE.

Area Under the Curve (AUCtau)
Up to approximately 36 weeks

Area Under the Curve (AUCtau) during the dosing intervals for ABBV-181.

Half-life (t1/2)
Up to approximately 36 weeks

ABBV-181 is an investigational small molecule being studied for the treatment of Human Immunodeficiency Virus (HIV), specifically HIV-1 infection. It is in Phase 1 clinical development and is not yet approved by regulatory authorities.

What does ABBV-181 target?

ABBV-181 targets PD-1, a protein involved in immune regulation. By modulating PD-1, the drug aims to alter immune responses in the context of HIV infection, though its exact therapeutic mechanism in this setting is still under investigation.

Who is developing ABBV-181?

ABBV-181 is being developed by AbbVie Inc., a biopharmaceutical company traded on the New York Stock Exchange under the ticker ABBV. The company is conducting clinical trials to evaluate the drug's safety and effects in people with HIV.

What phase is ABBV-181 in?

ABBV-181 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. Its safety and efficacy are still being evaluated in early-stage clinical trials.

What clinical trials is ABBV-181 in?

ABBV-181 has been studied in one completed Phase 1 clinical trial, identified as NCT04223804. This randomized, double-blind, placebo-controlled study evaluated the safety, pharmacokinetics, and pharmacodynamics of ABBV-181 in adult participants with HIV-1. The trial enrolled 41 participants across the United States, Australia, Canada, and Puerto Rico.

Is ABBV-181 the same as budigalimab?

Yes, ABBV-181 is also known as budigalimab. In clinical trial records, the drug is referred to as ABBV-181 (Budigalimab), indicating that both names refer to the same investigational compound being developed by AbbVie.
