NCT02318901

  Purpose
There will be two phase II cohorts for pembro plus trastuzumab: one cohort will be for patients with unresectable HER2 overexpressing gastric or GEJ cancers, the other cohort will be for patients with HER2 overexpressing metastatic breast cancer (MBC). The pembro plus ado-trastuzumab emtansine phase II arm will be for patients with HER2 overexpressing MBC. There will be two phase II cohorts for pembro plus cetuximab: one cohort will be for patients with HNSCC, the other cohort will be for patients with K-ras, B-raf, N-ras wildtype metastatic CRC.

Arm 3: Cycle length is 21 days. i.v. cetuximab 400 mg/m2 on cycle 1 day 1, then i.v. cetuximab 250 mg/m2 on day 8. Each subsequent cycle will be i.v. cetuximab 250 mg/m2 on days 1 and 8 every 21 days.

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patient has definitive histologically or cytologically confirmed unresectable or metastatic solid tumor.
  2. Patient has one or more tumor measurable as defined by RECIST 1.1 by CT scan (or PET/CT, if patient is allergic to CT contrast media).
  3. Patients can be enrolled only on one of the treatment arms on this trial.
  4. The investigator will select the appropriate treatment arm for the patient with the following requirements: (a) Patients cannot have had prior progression or intolerance to a specific Mab and then enrolled on an arm with that same Mab plus pembro, (b) The Mab on the arm selected must be considered standard of care or listed in the NCCN guidelines (www.nccn.org) for that cancer type. For Arm 1, patients with HER2 overexpressing MBC eligible for maintenance trastuzumab are allowed after taxane plus trastuzumab plus pertuzumab combination therapy.
  5. Have recovered from acute toxicities of prior treatment:

    1. > 3 weeks must have elapsed since receiving any investigational agent.
    2. > 2 weeks must have elapsed since receiving any radiotherapy, or ≥ 3 weeks or 5 half-lives whichever is shorter for treatment with cytotoxic or biologic agents ( ≥ 6 weeks for mitomycin or nitrosoureas). Chronic treatment with non-investigational gonadotropin-releasing hormone analogs or other hormonal or supportive care is permitted.

  6. Requiring daily corticosteroid dose ≥ 10 mg prednisone or equivalent per day.
  7. Patient has undergone major surgery, other than diagnostic surgery (e.g., surgery done to obtain a biopsy for diagnosis without removal of an organ), within 4 weeks prior to Day 1 of treatment in this study.
  8. Patient has a history of allergy or hypersensitivity to any of the study drugs or any of their excipients, or the patient exhibits any of the events outlined in the Contraindication or Special Warnings and Precautions sections of the product or comparator SmPC or Prescribing Information.
  9. Patient has serious medical risk factors involving any of the major organ systems, or serious psychiatric disorders, which could compromise the patient's safety or the study data integrity.
  10. Patient will be receiving any other anti-cancer therapy during participation in this trial.
  11. Prior treatment with pembro. Receipt of other PD-1 inhibitors or PD-L1 inhibitors is allowed.
  12. Active or prior documented autoimmune disease requiring systemic treatment within the past 2 years.

Exclusion Criteria for phase II portion only:
