First-in-human Study of M4076 in Advanced Solid Tumors (DDRiver Solid Tumors 410)

March 4, 2025 updated by: EMD Serono Research & Development Institute, Inc.

A First-in-human, Phase I, Open-label Study of the ATM Inhibitor M4076 in Participants With Advanced Solid Tumors (DDRiver Solid Tumors 410)

The purpose of this study was to determine the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), maximum tolerated dose (MTD) (if reached) and early signs of efficacy of M4076 monotherapy in participants with solid tumors in dose escalation (Part 1A). Once the recommended dose for expansion (RDE) was declared in Part 1A, a preliminary food effect cohort, Part 1B, will follow at the RDE determined from Part 1A.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Time Frame: Day 1 to Day 21 of Cycle 1 (21-day cycle)
A DLT was defined as the occurrence of any of following events that were judged by the study investigator, received at least 80% of the planned cumulative dose during the DLT period of each study intervention and completed the DLT period or additionally, participants who did not receive 80% of the planned total dose of study intervention, but at least 80% dosing of a different dose cohort and finished the DLT period are eligible for the DLT analysis set to be analyzed in the highest dose cohort for which they received 80% of dosing.

An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. The term TEAE is defined as AEs starting or worsening after the first intake of the study drug. TEAEs include both Serious TEAEs and non-serious TEAEs.

Baseline (Day 1) up to 30 days after the last dose of study drug administration (up to 603 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Confirmed Objective Response According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as Assessed by Investigator
Time Frame: Time from first study treatment up to 603 days
Confirmed objective response was defined as the number of participants with a confirmed objective response of complete response (CR) or partial response (PR). CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (SLD) of all lesions. Confirmed CR = at least 2 determinations of CR at least 4 weeks apart and before progression. Confirmed PR = at least 2 determinations of PR at least 4 weeks apart and before progression (and not qualifying for a CR).
Time from first study treatment up to 603 days
Duration of Response (DOR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) as Assessed by Investigator
Time Frame: Time from first documentation of objective response to the date of first documentation of PD or death due to any cause, assessed up to 603 days
DOR was defined for participants with confirmed response, as the time from first documentation of objective response (Complete Response [CR] or Partial Response [PR]) to the date of first documentation of progression disease (PD) or death due to any cause, whichever occurred first. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the SLD of all lesions. PD: At least a 20 percent (%) increase in the SLD, taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.
Time from first documentation of objective response to the date of first documentation of PD or death due to any cause, assessed up to 603 days
Progression-Free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) Assessed by Investigators
Time Frame: Time from the first dose of study intervention until occurrence of PD, death due to any cause or last tumor assessment (assessed up to 603 days)
PFS is defined as the time (in months) from date of first administration of study intervention to the date of the first documentation of progressive disease (PD) or death due to any cause, whichever occurs first. PD is defined as at least a 20 percent (%) increase in the sum of the longest diameter (SLD), taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions. PFS was to be estimated using Kaplan-Meier (KM) plots.
Time from the first dose of study intervention until occurrence of PD, death due to any cause or last tumor assessment (assessed up to 603 days)
Area Under the Plasma Concentration-Time Curve From Time Zero to Last Sampling Time (AUClast) of M4076
Time Frame: Day 1 and Day 8
Area under the plasma concentration vs time curve from time zero to the last sampling time t at which the concentration was at or above the lower limit of quantification (LLOQ). AUC0-tlast was to be calculated according to the mixed log-linear trapezoidal rule.
Day 1 and Day 8
Area Under Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of M4076
Time Frame: Day 1 and Day 8
The AUC from time zero (dosing time) extrapolated to infinity, based on the predicted value for the concentration at tlast, as estimated using the linear regression from lambda z determination. AUC0-inf = AUC0-tlast +Clast pred/ lambda z (single dose only)
Day 1 and Day 8
Maximum Observed Plasma Concentration (Cmax) of M4076
Time Frame: Day 1 and Day 8
Cmax was obtained directly from the concentration versus time curve.

Absolute Values in Ataxia-Telangiectasia Mutated (ATM) Pathway Readouts Assessed by Flow Cytometry and Immunohistochemistry: Gamma-H2AX
Time Frame: Baseline up to Day 23
gamma-H2AX is measured by flow cytometry and immunohistochemistry. Absolute values were reported for each participant as descriptive data for this outcome measure was not calculated. P= Part, D=Day, H=Hour in the below mentioned categories. Mean Fluorescent Intensity (MFI) is a number generated by the flow cytometer; an instrument that measures the fluorescent signal emitted by a sample. The stronger the fluorescent signal, the higher the MFI value detected by the instrument's acquisition software. The values displayed in the system represent each MFI measurement at different time points, with the MFI value for the blank sample subtracted.
