This study is a Phase 1 and pharmacologic open-labeled dose-escalation trial using a "3+3" design. Successive cohorts of three or more patients will be treated at escalating doses until a maximum tolerated dose is identified. Once the maximum tolerated dose is identified, an Expansion Cohort will be enrolled at that dose to further characterize safety and to explore pharmacodynamic endpoints.

Condition Intervention Phase
Locally Advanced/Metastatic or Recurrent Ovarian Cancer, Fallopian Tube Cancer,
Primary Peritoneal Cancer or Endometrial Cancer
Locally Advanced/Metastatic Her2 Non Overexpressing Breast Cancer
Drug: MM-121 plus Paclitaxel
Phase 1

Study Type: Interventional
Study Design: Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase 1, Pharmacologic and Pharmacodynamic Study of MM-121 in Combination With Paclitaxel in Patients With Advanced Gynecologic and Breast Cancers

Primary Outcome Measures:
  • Assessing number and severity of adverse events related to escalating doses of the MM-121 and paclitaxel combination [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To characterize the efficacy of the combination of MM-121 and paclitaxel using objective response rate and clinical benefit rate [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • To determine the pharmacokinetics (PK) of MM-121 when administered in combination with paclitaxel by measuring AUC, Tmax and Cmax [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • To determine whether MM-121, when administered in combination with paclitaxel, elicits an immune response [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Enrollment: 24
Study Start Date: October 2010
Study Completion Date: July 2014
Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MM-121 Drug: MM-121 plus Paclitaxel

Cohort 1:

MM-121 - 20 mg/kg loading dose followed by 12 mg/kg weekly IV Paclitaxel - 80mg/m2 weekly IV

Cohort 2:

MM-121 - 40 mg/kg loading dose followed by 20 mg/kg weekly IV Paclitaxel - 80mg/m2 weekly IV

Intermediate doses between cohorts 1 and 2 may also be considered.
