Study Details

Study Description

Brief Summary

This study was a Phase 1 and pharmacologic open-labeled dose-escalation trial using a "3+3" design to determine maximum tolerated dose/recommended Phase 2 dose.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

Successive cohorts of three or more patients were treated at escalating doses until a maximum tolerated dose/recommended phase 2 dose was identified. The study initially explored a dosing schedule every 7-days, which may have been modified to longer intervals under certain circumstances but did not expand to more than weekly. When the maximum tolerated dose/recommended Phase 2 dose was identified, an Expansion Cohort was enrolled at that dose to further characterize safety and to explore pharmacodynamic endpoints. There were 3 sites that participated.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Dose Escalation

Cohorts of escalating doses of MM-121 administered IV QW to determine MTD or RP2D + expansion cohort at MTD/RP2D

Drug: MM-121
Dose escalation Frequency - once weekly

  • Seribantumab, SAR256212
  • Outcome Measures

    Primary Outcome Measures

    1. Objective Response Rate and Duration [Time from first dose to date of progression, with a median of 7.1 weeks]

      To determine the number of patients reporting an objective response using RECIST v 1.1 where a Partial Response is defined as a >20% decrease in tumor burden from baseline and a Complete Response is defined as complete disappearance of tumor burden from baseline. Duration of response is defined as the length of time in weeks from observation of response until progression. NOTE: because no patients experienced an objective response as shown below, duration of response is not presented. No duration of response could be measured.

    2. Determine the Maximum Tolerated Dose Dependent on Reports of Dose-limiting Toxicities [From date of first dose to 30 days after termination, the longest 47 weeks]

      Using a 3+3 dose escalation model, the maximum tolerated dose was determined by assessing dose-limiting toxicities in each cohort from cohort 1-6. Cohort 1 began at 3.2 mg/kg IV QW and the dose escalated in separate cohorts from 6 mg/kg IV QW, 10 mg/kg IV QW, 15 mg/kg IV QW, 20 mg/kg IV QW, to the highest scheduled testing dose at 40 mg/kg one-time loading dose on cycle 1, week 1 followed by 20 mg/kg IV QW maintenance doses. If 3 patients were treated and passed the observation window, escalation to the next cohort was initiated. If a DLT was reported, 3-4 additional patients were enrolled and observed. If a DLT was observed in the expanded cohort, this dose was considered to be the maximum tolerated dose. The maximum tolerated dose was defined at the cohort in which two dose-limiting toxicities were observed, or as the highest target dose tested in the absence of DLTs. The determined MTD was considered the Recommended Phase 2 Dose and was used to open the expansion cohort.

    Secondary Outcome Measures

    1. To Describe the Dose-limiting Toxicity of MM-121 as a Monotherapy [From date of first dose to 30 days after termination, the longest 47 weeks]

      To establish the safety of escalating doses of MM-121 administered as a monotherapy in order to determine the recommended phase 2 dose. Dose-escalation conducted using standard 3+3 model to determine maximum tolerated dose. Reports of Dose-Limiting Toxicities (DLTs) were assessed to determine the MTD to be used for the expansion cohort. DLTs were not measured in the Expansion Cohort.

    2. To Determine the Pharmacokinetic and Immunogenicity Parameters of MM-121 [At Cycle 1, Week 1 pre-treatment, at the end of the infusion, and 2, 4, 8, 24, 48 and 72 hours after starting the infusion; pre-dose collections on Cycle 1, Week 2 and Cycle 2, Week 1 for all patients]

      Pharmacokinetic (PK) evaluation was performed on plasma samples obtained weekly for the first cycle of the study and then on day 1 of each additional cycle to assess pre-treatment trough concentrations of MM-121. The maximum observed concentration (Cmax) is presented and was calculated usig Non-compartmental analysis (NCA). Serum levels of MM-121 were measured at a central lab using an enzyme-linked immunosorbent assay (ELISA). Data is presented per dose level of MM-121 (3.2 mg/kg, 6 mg/kg, 10 mg/kg, 15 mg/kg, 20 mg/kg, 40/20 mg/kg). Immunogenicity data is not available.

    3. To Determine the Pharmacokinetic Parameters of MM-121 [At Cycle 1, Week 1 pre-treatment, at the end of the infusion, and 2, 4, 8, 24, 48 and 72 hours after starting the infusion; pre-dose collections on Cycle 1, Week 2 and Cycle 2, Week 1 for all patients]

      Pharmacokinetic (PK) evaluation was performed on plasma samples obtained weekly for the first cycle of the study and then on day 1 of each additional cycle to assess pre-treatment trough concentrations of MM-121. The AUC is presented and was calculated usig Non-compartmental analysis (NCA). Serum levels of MM-121 were measured at a central lab using an enzyme-linked immunosorbent assay (ELISA). Data is presented per dose level of MM-121 (3.2 mg/kg, 6 mg/kg, 10 mg/kg, 15 mg/kg, 20 mg/kg, 40/20 mg/kg).

    Title To Determine the Pharmacokinetic and Immunogenicity Parameters of MM-121
    Description Pharmacokinetic (PK) evaluation was performed on plasma samples obtained weekly for the first cycle of the study and then on day 1 of each additional cycle to assess pre-treatment trough concentrations of MM-121. The maximum observed concentration (Cmax) is presented and was calculated usig Non-compartmental analysis (NCA). Serum levels of MM-121 were measured at a central lab using an enzyme-linked immunosorbent assay (ELISA). Data is presented per dose level of MM-121 (3.2 mg/kg, 6 mg/kg, 10 mg/kg, 15 mg/kg, 20 mg/kg, 40/20 mg/kg). Immunogenicity data is not available.
    Time Frame At Cycle 1, Week 1 pre-treatment, at the end of the infusion, and 2, 4, 8, 24, 48 and 72 hours after starting the infusion; pre-dose collections on Cycle 1, Week 2 and Cycle 2, Week 1 for all patients

    Outcome Measure Data

    Analysis Population Description
    All patients. NOTE: There are 22 patients included in the final cohort (4 patients in dose escalation portion Cohort 6 + 18 patients in Expansion Cohort), as PK analysis was performed per dose level and not per cohort. Cohort 6 and the Expansion Cohort were administered the same dose, and therefore the analysis reflects all 22 patients.

    Adverse Events

    Time Frame AEs were collected from a patient's first dose until 30 days after treatment termination. SAEs were collected from time of informed consent until 30 days after termination. If related, events could be reported at any time after termination.
    Adverse Event Reporting Description All related AEs ongoing at the time of treatment discontinuation were followed until resolution. Investigators were to report any AEs/SAEs assumed to be related any time, even if occurring more than 30 days after last dose. Though different for each patient, on average, patients could be followed for related AEs/SAEs for ~1 year after termination.
