Siremadlin

Novartis Pharmaceuticals

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.

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.

azacitidine

A study of siremadlin in combination with venetoclax plus azacitidine in adult participants with AML who are ineligible for chemotherapy.

The primary purpose of this study was to assess whether siremadlin in combination with venetoclax plus azacitidine can enhance the clinical response in unfit AML patients without unacceptable levels of treatment-emergent toxicities.

The recommended dose of siremadlin in combination with venetoclax plus azacitidine will be determined to be explored further in the expansion phase and the preliminary efficacy in achieving Complete Remission (CR) will be evaluated in participants who responded sub-optimally to first-line venetoclax plus azacitidine treatment.

The study was planned to be conducted in two parts. The primary purpose of Part 1 (Safety Run- in) was to rule out excessive toxicity of siremadlin when administered in combination with venetoclax plus azacitidine while the primary purpose of Part 2 (Expansion) was to evaluate the preliminary efficacy of siremadlin when combined with venetoclax plus azacitidine in the respective patient population.

The study treatment (siremadlin in combination with venetoclax plus azacitidine) is administered in cycles with a planned duration of 28 days and will continue until the participants experience disease progression/relapse or unacceptable toxicity.

The initial enrollment plan and safety review was as follow:

* In the Safety run-in part, 9-15 participants were planned to be enrolled in each arm. Approximately 3-6 participants were planned to be enrolled at the starting dose level of siremadlin in combination with venetoclax plus azacitidine in both arms independently. Provided the starting dose level is determined to be safe, approximately 6-9 additional participants were planned to be enrolled at dose level +1. Safety review meetings were planned to take place involving participating investigators and the Sponsor Team to make decisions regarding siremadlin dose and determine the recommended dose for expansion.
* Approximately 26 patients were planned to be treated at the recommended dose in the expansion part.

In the safety run-(Part 1) 27 sites were open for recruitment with 28 patients screened and 14 patients enrolled.

After enrolling 14 patients (6 patients in Arm 1 and 8 patients in Arm 2), Novartis took the decision to put the enrollment in permanent halt and terminate the siremadlin program. For that reason, the enrollment in Part 2 (expansion phase) will not be open. The Novartis decision was not driven by any safety concerns.

This endpoint will not be analyzed since the recommended dose was not determined due to early termination.

Assessment of CR/CRh rate and CR/CRi rate.

Assessment of duration of CR/CRh and duration of CR/CRi.

To assess rate of early mortality at 30 day and 60 days from start of study treatment

AUC0-t: The area under the concentration vs. time Curve (AUC) from time zero to specified time point.

AUClast is the AUC from time zero to the last quantifiable concentration point (last) (mass x time x volume -1).

AUCtau is the AUC to the end of the dosing interval as when possible PK samples will be collected up to 24 h postdose for siremadlin and venetoclax. Steady-state will be assumed on Day 5 (AUCtau, ss) in case of continuous dosing.

To characterize the PK of siremadlin, venetoclax and azacitidine administered in combination in each arm. Cmax is the maximum (peak) observed plasma, blood, serum or other body fluid drug concentration following drug administration (mass x volume -1)

PK parameter Tmax and concentration vs time profiles of siremadlin, venetoclax and azacitidine. Tmax is the time to reach maximum (peak) plasma, blood, serum, or other body fluid drug concentration after drug administration (time).
