Experimental: MGAH22
Anti-HER2 monoclonal antibody (margetuximab)
|
Biological: MGAH22
MGAH22 will be administered by IV infusion once per week for 4 weeks in the following dose escalation cohorts: 0.1, 0.3, 1.0, 3.0, and 6.0 mg/kg; and once every 3 weeks in the following dose escalation cohorts: 10.0, 15.0, and 18.0 mg/kg. An additional cohort of up to 15 patients with breast or gastric cancer will be enrolled and treated at a dose of 15 mg/kg every three weeks. |
Detailed Description:
An open-label, multi-dose, single-arm, multi-center, Phase 1, dose-escalation study will be conducted to define the toxicity profile, MTD, PK, immunogenicity, and potential antitumor activity of MGAH22 in patients with refractory HER2 positive breast cancer and patients with other carcinomas that overexpress HER2 for whom no standard therapy is available. After an MTD has been defined, an additional cohort of patients will be treated at the MTD to obtain further information regarding the safety of the chosen dose, to definitively describe PK, and to evaluate potential anti-tumor activity of MGAH22.
Patients will be monitored for a minimum of four weeks after administration of the final dose of MGAH22. The National Cancer Institute's (NCI's) Common Terminology Criteria for Adverse Events (CTCAE), v.4.0, will be used for grading AEs except as noted within the protocol. Study assessments will include AE monitoring, ECG monitoring, PK analysis of serum MGAH22, determination of the serum concentration of soluble MGAH22 and tumor markers, and an assessment of potential anti-MGAH22 antibody [human anti-chimeric antibody (HACA)] response.
Tumor response assessments using Study Day 43 CT scans will be performed approximately six weeks after the first MGAH22 dose for each patient. Patients with evidence of disease regression (partial or complete response or stable disease by RECIST criteria) will be allowed to continue therapy at the same dose, or at a reduced dose if warranted by DLT or significant AE in Cycle 1. Subsequent cycles which will begin on Study Day 50 will consist of MGAH22 administration on Study Days 1, 8, and 15 of each 28-day cycle, with tumor evaluation every other cycle. Responding patients may receive continued antibody therapy until evidence of progression of disease is documented or the patient experiences DLT.
Eligibility| Ages Eligible for Study: | 18 Years and older (Adult, Senior) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Histologically or cytologically confirmed carcinoma that overexpresses HER2 by immunohistochemistry (2+ or 3+ positivity by HercepTest or equivalent).
- Progressive disease during or after last treatment regimen.
- Appropriate treatment history for histological entity.
- ECOG Performance Status <= 1.
- Life expectancy >= 3 month.
- Measurable disease
- Acceptable laboratory parameters and adequate organ reserve.
- Baseline LVEF >50%
Exclusion Criteria:
- Lifetime anthracycline exposure > 350 mg/m2 of doxorubicin or equivalent
- Major surgery within four weeks before enrollment.
- Known hypersensitivity to murine or recombinant proteins, polysorbate 80, or any excipient contained in the drug formulation.
- Second primary malignancy that has not been in remission for greater than 3 years. Treated non-melanoma skin cancer, cervical carcinoma in situ on biopsy, or squamous intraepithelial lesion on PAP smear, localized prostate cancer (Gleason score < 6), or resected melanoma in situ are exceptions and do not require a 3 year remission.
- Active viral, bacterial, or systemic fungal infection requiring parenteral treatment within four weeks of enrollment. Patients requiring any oral antiviral, fungal, or bacterial therapy must have completed treatment within one week of enrollment.
- History of chronic or recurrent infections that require continual use of antiviral, antifungal, or antibacterial agents.
- History of deep vein thrombosis, pulmonary embolism, myocardial infarction, or stroke within three months of enrollment.
- Known history of central nervous system (CNS) metastatic disease with evidence of residual or recurrent disease upon entry.
- New York Heart Association class III or IV heart disease.
