Maximum Observed Blood Concentrations (Cmax) for siremadlin. Blood samples will be collected to measure Cmax at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Area Under Plasma Concentration-time Curve from time zero to the last measurable concentration sampling time (AUClast) for siremadlin. Blood samples will be collected to measure AUClast at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Area Under Plasma Concentration from time zero to time "t" (AUC0-t). The definition of "t" may be data driven post-hoc to mitigate bias in the exposure comparision due to between-group differences in Tlast for siremadlin. Blood samples will be collected to measure AUC0-t at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Area Under Plasma Concentration from time zero to 24-hour post-dose sampling time (AUC0-24h) for siremadlin. Blood samples will be collected to measure AUC0-24h at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Last measurable plasma concentration (Tlast) for siremadlin. Blood samples will be collected to measure Tlast at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Time to Reach Maximum Blood Concentrations (Tmax) for siremadlin. Blood samples will be collected to measure Tmax at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Apparent total body clearance of siremadlin from plasma (CL/F). Blood samples will be collected to measure CL/F at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
Apparent volume of distribution during terminal elimination phase (Vz/F) of siremadlin. Blood samples will be collected to estimate Vz/F at indicated timepoints. Pharmacokinetic (PK) parameters will be calculated based on siremadlin blood concentrations.
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.
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.
A dose-limiting toxicity (DLT) is defined as an adverse event (AE) or abnormal laboratory value considered by the Investigator to be at least possibly related to siremadlin as a single contributor or in combination with other component(s) of study treatment that occurs beginning the first day of siremadlin dosing in the study until end of cycle 1.
Assessed by CR rate. CR rate is defined as the percentage of participants with best overall response of complete remission (CR) as per investigator assessment.
DLTs in the first cycle of treatment.

| Arm 1: Adult participants with unfit AML who responded sub-optimally to standard of care | EXPERIMENTAL | Unfit adult participants with unfit AML who responded sub-optimally to at least 2 and not more than 4 cycles of first-line venetoclax plus azacitidine therapy. Siremadlin was adminstered at a dose of 20 mg QD which could be increased based on toxicities; venetoclax was administered at 400 mg once daily and azacitidine was administered at 75 mg/m\^2. |
| Arm 2: Adult participants with newly diagnosed unfit AML with high risk clinical features | EXPERIMENTAL | Adult participants with unfit AML who were newly diagnosed and presenting with high-risk clinical features (which related to factors conferring to a low likelihood of response to venetoclax plus azacitidine) and with adverse genetic risk stratification (according to ELN 2022) (Except TP53 mutation positive participants). Siremadlin was administered at a dose of 20 mg QD which could be increased based on toxicities; venetoclax was administered at 400 mg once daily and azacitidine was administered at 75 mg/m\^2. |

Siremadlin is an investigational small molecule being studied in oncology, specifically in acute myeloid leukemia and in hepatic impairment. It has been evaluated in a Phase 1 study in adults with acute myeloid leukemia who are ineligible for chemotherapy, and in a Phase 1 pharmacokinetics and safety study in participants with mild, moderate, and severe hepatic impairment.
Siremadlin targets TP53 and MDM2. It is classified as an inhibitor, meaning it acts on the MDM2 pathway that regulates the tumor suppressor protein TP53. This mechanism is designed to restore TP53 activity in cancers where that pathway is dysregulated, and the clinical program has used biomarker selection.
Siremadlin is developed by Novartis AG, which trades under the ticker NVS. Novartis is the sponsor of the clinical studies evaluating the compound, including the Phase 1 acute myeloid leukemia combination study and the Phase 1 hepatic impairment pharmacokinetics study.
Siremadlin is in Phase 1 clinical development. It is an investigational agent and is not approved for any indication. The completed studies include a Phase 1 trial in acute myeloid leukemia and a Phase 1 pharmacokinetics and safety study in hepatic impairment, with no active trials currently listed.
Siremadlin has been studied in two completed Phase 1 trials. NCT05155709 evaluated siremadlin in combination with venetoclax plus azacitidine in adults with acute myeloid leukemia who are ineligible for chemotherapy, enrolling 14 participants. NCT05599932 evaluated the pharmacokinetics and safety of siremadlin in participants with mild, moderate, and severe hepatic impairment, enrolling 38 participants in the United States.
Yes, siremadlin is also known as HDM201. The two names refer to the same Novartis compound, and the hepatic impairment study is titled as a pharmacokinetics and safety study of siremadlin (HDM201). Searches for either name point to the same investigational MDM2 inhibitor program.
