Berzosertib Human Mass Balance Study (DDRiver Solid Tumors 208)

September 25, 2024 updated by: Merck Healthcare KGaA, Darmstadt, Germany, an affiliate of Merck KGaA, Darmstadt, Germany

Phase I Study to Evaluate the Mass Balance, PK, Metabolism and Excretion of Berzosertib (Intravenous) Containing Microtracer [14C]Berzosertib in Participants With Advanced Solid Tumors (DDRiver Solid Tumors 208)

The study was conducted in two periods, Period 1 (mass balance) and Period 2 (extension). The purpose of Period 1 of this study was to provide a quantitative characterization of the mass balance, rates and routes of elimination, and metabolic pathways after a single intravenous administration of [14C]berzosertib. The purpose of Period 2 was to assess safety and efficacy of berzosertib in combination with topotecan.

Vz was calculated by dividing the dose with area under the concentration time curve from time zero to infinity multiplied with terminal elimination rate constant Lambda(z). Vz = Dose/AUC0-inf multiply Lambda z.

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
Period 1 and Period 2: Number of Participants With Clinically Significant Changes From Baseline in Vital Signs
Time Frame: Period 1: Baseline up to Day 14; Period 2: From Day 1 of period 2 until disease progression or other criteria for study intervention discontinuation are met (up to a maximum of approximately 16 months)
Vital signs included body temperature, heart rate, systolic and diastolic blood pressure and respiration rate. Number of participants with clinically significant findings in vital signs were reported. Clinical significance was decided by Investigator.
Period 1: Baseline up to Day 14; Period 2: From Day 1 of period 2 until disease progression or other criteria for study intervention discontinuation are met (up to a maximum of approximately 16 months)

Time Frame: Period 1: Baseline up to Day 14; Period 2: From Day 1 of period 2 until disease progression or other criteria for study intervention discontinuation are met (up to a maximum of approximately 16 months)
12-lead ECG recordings included rhythm, heart rate (as measured by RR interval), PR interval, QRS duration, and QT interval. 12-lead ECG recordings were obtained after the participants have rested for at least 10 minutes in semi-supine position. Clinical significance was determined by the investigator. The number of participants with clinically significant changes from baseline in 12-lead ECG findings were reported.

Time Frame: Period 1: Baseline up to Day 14; Period 2: From Day 1 of period 2 until disease progression or other criteria for study intervention discontinuation are met (up to a maximum of approximately 16 months)
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product, regardless of causal relationship with this treatment. Therefore, an AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, regardless if it is considered related to the medicinal product.
