Brief Summary

This study is an open-label Phase 1 trial of MM-111.

Detailed Description

Phase 1: Patients with any solid tumor type may be enrolled to evaluate the safety and tolerability of MM-111.

Inclusion Criteria
  • Patients must have histologically or cytologically confirmed advanced cancer that is:

    • HER2 amplified (IHC 2+ or greater) based on archived tumor evaluation
    • Heregulin positive based on a study required fresh biopsy sample performed at screening and confirmed by central laboratory
  • Patients must have blocks of archived formalin-fixed, paraffin-embedded tumor tissue available for sectioning and immunohistochemical staining

  • Patient's cancer must have recurred or progressed following standard therapy, have not responded to standard therapy, or for which no standard therapy exists.

  • Patients must be >= 18 years of age

  • Patients or their legal representatives must be able to understand and sign an informed consent

  • Patients may have measurable or non-measurable tumor(s)

  • Patients should have ECOG Performance Score (PS) 0 or 1

  • Patients must have adequate bone marrow reserves as evidenced by:

    • Absolute neutrophil count (ANC) >= 1,500/uL and
    • Platelet count >= 100,000/uL
    • Hemoglobin >= 9 g/dL
  • Patients must have tumor tissue amenable to biopsy

  • Patients must be willing to undergo biopsy prior to treatment to MM-111

Exclusion Criteria
  • Patients for whom potentially curative antineoplastic therapy is available
  • Patients who are pregnant or lactating
  • Patients with an active infection or with an unexplained fever greater than 38.5 C during screening visits or on the first scheduled day of dosing. (At the discretion of the investigator, patients with tumor fever may be enrolled)
  • Patients with untreated and/or symptomatic primary or metastatic CNS malignancies (patients with CNS metastases who have undergone surgery or radiotherapy, whose disease is stable, and who have been on a stable dose of corticosteroids for at least 2 weeks prior to the first scheduled day of dosing will be eligible for the trial
  • Patients with known hypersensitivity to any of the components of MM-111 or who have had hypersensitivity reactions to fully human monoclonal antibodies (patients with a history of hypersensitivity to trastuzumab, a humanized antibody, are not excluded)
  • Patients with known HIV, hepatitis B or C (if patients have previously been treated for C and have undetectable viral loads, they can be considered eligible for the trial)

Primary Outcome Measures
NameTimeMethod
Maximum Tolerated Dose (MTD) or Maximum Feasible Dose28 days

The Maximum Tolerated Dose (MTD) was defined as the highest dose level in which a DLT is experienced by fewer than two patients in a cohort of 3 - 6 patients. If a DLT is observed in at least two patients in a cohort of 3 - 6 patients, the MTD will be determined to have been exceeded and an additional three patients (up to a total of six) are to be treated at the next lower dose level.

Secondary Outcome Measures

To Explore the Role Functional Imagining (FDG-PET CT Scan), as a Predictor of Clinical ActivityDecember 2011
To Determine the Clinical Activity of MM-111 in Patients Based on Objective Response Rate (ORR), Duration of Response (DoR), Progression Free Survival (PFS), and 16 & 24-week Clinical Benefit Rate (CBR)December 2011
