About this study

Official title: A Phase 1, Open-label, Single-dose, Multi-center, Parallel Group Study to Evaluate the Pharmacokinetics of JDQ443 in Participants With Mild, Moderate or Severe Hepatic Impairment Compared to Matched Healthy Control Participants.

The purpose of this study is to evaluate the effect of hepatic impairment on the systemic pharmacokinetics (PK), safety, and tolerability of JDQ443 in participants with varying degrees of hepatic impairment.

Read the detailed description

This is a Phase 1, open-label, single-dose, multi-center, parallel group study to evaluate the PK of oral JDQ443 in participants with mild, moderate, and/or severe hepatic impairment compared to matched healthy control participants.

The study comprises a 28-day Screening period (Days -28 to -2), a baseline evaluation period (Day -1), a single dose administration of 200 mg of JDQ443 (Day 1), and a follow-up period of 4 days (Days 2 to 4) for PK sample collection. All participants should have a post-study safety follow-up contact conducted approximately 30 days after last administration of study treatment. The study will be considered complete once all the participants have finished the required assessments or have dropped out or been lost to follow-up.

A total of up to 48 participants will be enrolled in this study. Approximately 8 participants will be enrolled in each of mild (Child-Pugh A; Group 2), moderate (Child-Pugh B; Group 3), and severe (Child-Pugh C; Group 4) hepatic impairment groups (to have at least six evaluable participants in each group). Each participant in the healthy control group (Group 1) will be matched to one or more evaluable participants with hepatic impairment with respect to age, body weight and sex. All participants will receive a single JDQ443 dose. Upon completion of mild and moderate impairment groups, as well as matching control participants, an interim analysis will be conducted to compare the PK exposure of the two hepatic impaired groups (Groups 2 and 3) to that of the control participants. The interim analysis is to mitigate the potential safety risks in participants with severe hepatic impairment. If the interim analysis results do not show a clinically relevant increase in exposure of JDQ443 and is well tolerated from a safety perspective, then severe hepatic impairment participants may be enrolled. Participants with severe hepatic impairment will be enrolled only after the completion of the interim analysis.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing JDQ443 in people with Small Cell Lung Carcinoma, run by Novartis Pharmaceuticals at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Area Under the Plasma Concentration-time Curve From Time Zero to the Last Quantifiable Concentration (AUClast) of JDQ443 (time frame: Day 1 (Pre-dose), 0.5, 1, 1.5, 2, 3 , 4 , 6 , 8 , 12 , 24 , 36 , 48 and 72 hours post-dose). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Oct 2025.
