A Study of JNT-517 in Participants With Phenylketonuria (PKU)

The goal of this Phase 3, randomized study is to assess the safety, efficacy, tolerability, and pharmacokinetics (PK) of oral JNT-517 in adults (18 years of age or older) with PKU. Participants will receive either JNT-517 or placebo and will be blinded to their treatment assignment. Participants will have a 2 in 3 (or approximately 67%) chance of receiving JNT-517 during the first part of the study which will last approximately six weeks. During the second part of the study every participant who continues in the study will receive one of two doses of JNT-517 for an additional 46 weeks. The study requires a screening period of up to 35 days to ensure dietary stabilization and amino acid levels required to meet study eligibility. In total, participation in the study could last for up to 400 days. Participants will: Take 75 mg JNT-517 or 150 mg JNT-517, or a placebo BID (2x per day) for approximately 365 days; Visit the clinic or have a mobile health nurse visit your home for checkups and tests; Collect urine sample at home and bring to clinic on specified days; Keep a food diary 3 days before each study visit

A Trial in Healthy Adult Participants and Adults With Autoimmune Disease to Test How HBM7020 is Tolerated and Absorbed in the Body

This first-in-human study evaluates the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of HBM7020. The study will enroll healthy participants at low doses, followed by participants with moderate to severe autoimmune diseases with predominant B-cell involvement. Eligible participants include patients with systemic lupus erythematosus (SLE), systemic sclerosis (SSc), Sjögren's disease (SjD), and rheumatoid arthritis (RA).

A Study of Quabodepistat-containing Regimens for the Treatment of Drug-resistant Pulmonary Tuberculosis

This study aims to assess quabodepistat-based treatment regimens for RR/MDR-TB. The study will enroll adults and adolescents with rifampicin-resistant or multidrug-resistant pulmonary TB. The main goal is to see if a new drug called quabodepistat, when combined with other TB drugs, can shorten treatment duration to 4 months and be as effective and safer than current WHO endorsed treatment regimen given for 6-months. The study will compare different drug combinations in two groups of patients: those whose TB is sensitive to fluoroquinolones and those whose TB is resistant to fluoroquinolones. Participants will be randomly assigned to receive either the new treatment or the standard treatment. The study will last for 16 months for each participant and will measure how well the treatments work and how safe they are.

A Long-Term Study of JNT-517 in Participants With Phenylketonuria

The goal of this Phase 3, open-label study is to evaluate the long-term safety of JNT-517 in pediatric and adult participants with Phenylketonuria (PKU) after completion of either Study JNT517-101 (NCT05781399) or JNT517-201 (NCT06637514) as well as participants who have not participated in a prior JNT-517 study. In this trial, all participants will receive JNT-517 using age- and weight-banded dosing as outlined in the protocol, regardless of any dose received in a previous study.
