To evaluate the safety and tolerability of escalating doses of MM-121 + certain anticancer therapies
This study was a Phase 1 and pharmacologic dose-escalation trial of MM-121 in combination with certain anticancer therapies. The dose-escalation portion of the study employed a 3 + 3 design to assess the safety, tolerability, and pharmacokinetics of MM-121 administered weekly in combination with certain anticancer therapies in patients with advanced/recurrent cancer. Doses of MM-121 and/or the anticancer therapy were escalated until either the MTD is identified or the combination was shown to be tolerable at the highest planned doses.

To Evaluate the Safety and Tolerability of Escalating Doses of the MM-121 Anticancer Therapies
Safety and tolerability data presented in detail in the adverse events and serious adverse events section of the results posting
Time frame: From date of first dose to 30 days after termination, the longest 88.1 weeks
To Determine the Maximum Tolerated Dose (MTD) of MM-121 in Combination With Anticancer Therapies: MM-121 Doses
Using a 3+3 dose escalation model, the maximum tolerated dose of each therapy combination was determined by assessing dose-limiting toxicities in each cohort. 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 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. Dose Levels (3 week cycles) MM-121 doses tested: 20 mg/kg IV one-time loading dose then 12 mg/kg IV QW (20/12 mg/kg); 40/20 mg/kg Gemcitabine doses tested: 1000 mg/m2 Day 1 and 8 Pemetrexed doses tested: 500 mg/m2 Day 1 Carboplatin doses tested: 5 or 6 AUC Day 1 Cabazitaxel doses tested: 20 or 25 mg/m2 Day 1 of 3
Time frame: From date of first dose to 30 days after termination, the longest 88.1 weeks

To Determine the Maximum Tolerated Dose (MTD) of MM-121 in Combination With Anticancer Therapies: Carboplatin
Maximum Tolerated Dose reported in Target AUC, as calculated by the Calvert Formula Using a 3+3 dose escalation model, the maximum tolerated dose of each therapy combination was determined by assessing dose-limiting toxicities in each cohort. 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 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.

To Characterize Dose-limiting Toxicities (DLTs) Associated With the Combination of MM-121 With Anticancer Therapies
To establish the safety of escalating doses of MM-121 administered in combination with multiple anti-cancer therapies 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.
Time frame: From date of first dose to 30 days after termination, the longest 88.1 weeks
Objective Response Rate
To determine the number of patients reporting an objective response using RECIST v 1.1 where a Partial Response (PR) is defined as \>20% decrease in tumor burden from baseline and a Complete Response (CR) is defined as complete disappearance from tumor burden from baseline. Objective Response is presented as the total # patients with PR or CR.
Time frame: patients were assessed for response during their time on study, the longest of which was 88.1 weeks
Pharmacokinetics
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. Non-compartmental analysis (NCA) was performed to calculate standard PK parameters, including the maximum observed concentration (Cmax). 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 (12 mg/kg, 20 mg/kg, or 40/20 mg/kg).
Time frame: Collections taken at Cycle 1, Week 1 for all patients at start of the infusion (pretreatment), at the end of the infusion, and at 2, 4, 24 and 48 hours after the start of the MM-121 infusion
Pharmacokinetics (AUClast)
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. Non-compartmental analysis (NCA) was performed to calculate standard PK parameters, including the AUClast. 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 (12 mg/kg, 20 mg/kg, or 40/20 mg/kg) and per study part (Part 1 or Part 2).
Time frame: Collections taken at Cycle 1, Week 1 for all patients at the start of the infusion (pretreatment), at the end of the infusion, and at 2, 4, 24 and 48 hours after the start of the MM-121 infusion
Immunogenicity
Samples were collected to determine the presence of an immunologic reaction to MM-121 (i.e. human anti-human antibodies).
Time frame: Samples were collected for all patients pre-dose on all cycles for duration of treatment, the longest of which was 88.1 weeks, and a collection was made post-infusion in any case of infusion reaction
