About this study
Official title: A Phase 1, Open-label, Multi-center, Single-dose, Parallel Group Study to Evaluate the Pharmacokinetics of Siremadlin (HDM201) in Participants With Mild, Moderate and Severe Hepatic Impairment Compared to Matched Healthy Control Participants
The main purpose of this study is to evaluate the effect of varying degrees of impaired hepatic function (by Child Pugh classification) on the plasma PK of siremadlin after a single oral dose. In addition, safety and tolerability of siremadlin after a single oral dose will be evaluated. The results of this study will inform the decision whether a dose adjustment may be recommended when treating patients with various degrees of impaired hepatic function.
Read the detailed description
Participants will be recruited into one of 4 groups according to the Child-Pugh classification score. Participants with HI will be enrolled into either mild (Child-Pugh A; Group 2), moderate (Child Pugh B; Group 3) or severe (Child-Pugh C; Group 4) HI groups. Healthy control participants (Group 1) will be matched to 1 or more participants with HI with respect to age (± 10 years), body weight (± 20%) and sex. Each participant in the matched healthy control group (Group 1) can be matched to participant(s) in any HI group (Groups 2, 3, and 4).
The study will enroll the four groups in parallel. Therefore, enrollment in Group 1 will remain open until enrollment in the mild, moderate and severe HI groups is complete and each HI participant has a matched healthy control (Group 1) participant. Participants from Group 1 will be enrolled after at least 3 participants from each of Groups 2 and 3 have completed all scheduled assessments.
The study consists of a screening period of up to 28 days (Days -29 to -2), a baseline evaluation on Day -1, a single dose administration of siremadlin on Day 1 followed by PK sampling up to 144 hours post-dose (Day 7). All baseline safety evaluation results must be available and reviewed prior to the dosing. All eligible participants will be domiciled from Day -1 until Day 7.
Safety assessments will include physical examinations, ECGs, vital signs, standard clinical laboratory evaluations (hematology, blood chemistry, urinalysis, coagulation), AE and serious adverse event (SAE) monitoring.
All participants will have a post-study safety follow-up contact conducted approximately 30 days after administration of study treatment. The study will be considered complete once all the participants have finished the required assessments, dropped out, or been lost to follow-up before completing the required assessments.
The total study duration for each participant is expected to be up to maximum of 59 days, including the Screening period and the 30-day post-study safety contact follow up period.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The main purpose of this study is to evaluate the effect of varying degrees of impaired hepatic function (by Child Pugh classification) on the plasma PK of siremadlin after a single oral dose. In addition, safety and tolerability of siremadlin after a single oral dose will be evaluated. The results of this study will inform the decision whether a dose adjustment may be recommended when treating patients with various degrees of impaired hepatic function.
Detailed description
Participants will be recruited into one of 4 groups according to the Child-Pugh classification score. Participants with HI will be enrolled into either mild (Child-Pugh A; Group 2), moderate (Child Pugh B; Group 3) or severe (Child-Pugh C; Group 4) HI groups. Healthy control participants (Group 1) will be matched to 1 or more participants with HI with respect to age (± 10 years), body weight (± 20%) and sex. Each participant in the matched healthy control group (Group 1) can be matched to participant(s) in any HI group (Groups 2, 3, and 4).
The study will enroll the four groups in parallel. Therefore, enrollment in Group 1 will remain open until enrollment in the mild, moderate and severe HI groups is complete and each HI participant has a matched healthy control (Group 1) participant. Participants from Group 1 will be enrolled after at least 3 participants from each of Groups 2 and 3 have completed all scheduled assessments.
The study consists of a screening period of up to 28 days (Days -29 to -2), a baseline evaluation on Day -1, a single dose administration of siremadlin on Day 1 followed by PK sampling up to 144 hours post-dose (Day 7). All baseline safety evaluation results must be available and reviewed prior to the dosing. All eligible participants will be domiciled from Day -1 until Day 7.
Safety assessments will include physical examinations, ECGs, vital signs, standard clinical laboratory evaluations (hematology, blood chemistry, urinalysis, coagulation), AE and serious adverse event (SAE) monitoring.
All participants will have a post-study safety follow-up contact conducted approximately 30 days after administration of study treatment. The study will be considered complete once all the participants have finished the required assessments, dropped out, or been lost to follow-up before completing the required assessments.
The total study duration for each participant is expected to be up to maximum of 59 days, including the Screening period and the 30-day post-study safety contact follow up period.

Time frame: pre-dose, 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 10 hours, 12 hours, 24 hours, 36 hours, 48 hours, 72 hours, 96 hours, 120 hours, and 144 hours
Terminal Elimination Half-life (T1/2) for siremadlin. Blood samples will be collected to measure T1/2 at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Pharmacokinetics (PK): AUCinf
Time frame: pre-dose, 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 10 hours, 12 hours, 24 hours, 36 hours, 48 hours, 72 hours, 96 hours, 120 hours, and 144 hours
Area Under Plasma Concentration from time zero to infinity (AUCinf). Blood samples will be collected to measure AUCinf at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Siremadlin in people with Hepatic Impairment, run by Novartis Pharmaceuticals at 3 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 13 inclusion and 37 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 9 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 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?
Pharmacokinetics (PK): Cmax (time frame: pre-dose, 0.5 hours, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 8 hours, 10 hours, 12 hours, 24 hours, 36 hours, 48 hours, 72 hours, 96 hours, 120 hours, and 144 hours). 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 9 Jul 2025.
