Study of MEDI-547 to Evaluate the Safety, Tolerability, and Biologic Activity of IV Administration in Subjects With Relapsed or Refractory Solid Tumors

For the dose-escalation cohort: cancer relapsed or refractory to at least 1 prior standard care systemic regimen standard therapy with previous histological confirmation of diagnosis of fallopian tube, primary peritoneal, endometrial, cervical, prostate, non-small cell lung, esophageal, gastric, bladder, and renal cell carcinomas or melanoma. Subjects with relapsed or refractory breast, epithelial ovarian, or colon cancer with previous histological confirmation of diagnosis must have progressed through more than 1 prior regimen of therapy. For patients enrolling at the NCI, pathology must be confirmed by the Department of Pathology, CCR, NCI.

For the dose-expansion cohort: relapsed or refractory epithelial ovarian cancer with progression through more than 1 prior regimen of therapy, or relapsed or refractory fallopian tube, or primary peritoneal cancer with progression after at least 1 prior standard care systemic regimen, with previous histological confirmation of cancer diagnosis. For patients enrolling at the NCI, pathology must be confirmed by the Department of Pathology, Center for Cancer Research (CCR), NCI.

Patients with the following histologic epithelial ovarian cancer cell types are eligible: Serous adenocarcinoma, endometrioid adenocarcinoma, mucinous adenocarcinoma, undifferentiated carcinoma, clear cell adenocarcinoma, mixed epithelial carcinoma, transitional cell carcinoma, malignant Brenner's Tumor, or adenocarcinoma not otherwise specified (NOS).

For the dose-expansion cohort of subjects with relapsed or refractory ovarian cancer, subjects must have an archival tumor sample that demonstrates EphA2 expression by immunohistochemical stain.

Males or females at least 18 years of age at the time of obtaining informed consent.

Women of childbearing potential must have a negative serum pregnancy test within 72 hours prior to MEDI-547 administration; and men and women of reproductive potential must agree to practice an effective method of avoiding pregnancy (this is not to include oral or implanted contraceptives (such as the "pill", the "patch", a Depo Provera shot, or hormone laced intrauterine device, but allows the following: non hormonal (copper), intrauterine device, female condom, diaphragm with spermicide, cervical cap, abstinence, use of a condom by the sexual partner or sterile sexual partner) beginning at the time the ICF is signed, and must agree to continue using such precautions while receiving MEDI-547 through 30 days after the last dose of MEDI-547.

For the dose-escalation cohort: measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) criteria is desirable but not required. The following are not considered measurable: pleural effusion or ascites; osteoblastic/osteoclastic lesions or evidence of disease on bone scan alone; progressive irradiated lesions alone, bone marrow involvement, brain metastases, malignant hepatomegaly by physical exam alone; or chemical markers (eg, CA-125, carcinoembryonic antigen \[CEA\], or prostate specific antigen \[PSA\]). Recurrent disease following surgery or radiotherapy is measurable provided that 30 days have elapsed since treatment and that measurable disease exists outside the radiation port, or there is clear progression within the radiation port.

For the dose-expansion cohort: measurable disease, by RECIST criteria is required. The following are not considered measurable: pleural effusion or ascites; osteoblastic/osteoclastic lesions or evidence of disease on bone scan alone; progressive irradiated lesions alone, bone marrow involvement, brain metastases, malignant hepatomegaly by physical exam alone; or chemical markers (eg, CA-125, CEA, or PSA). Recurrent disease following surgery or radiotherapy is measurable provided that 30 days has elapsed since treatment and that measurable disease exists outside the radiation port, or there is clear progression within the radiation port.

Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2.

Life expectancy of greater than 16 weeks.

For subjects who had prior treatment with chemotherapy, biological therapy, radiotherapy, or investigational therapy or had prior surgery: eligible for study entry if at least 30 days have passed since their treatment/surgery, provided that all toxicities related to prior treatment have resolved to ≤ Grade 1 severity by National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 (NCI CTCAE v3.0 and all surgical wounds have healed.

Prior immunotherapy with approved agents (eg, trastuzumab, cetuximab, panitumumab, bevacizumab) is allowable if at least 30 days have passed.

Absolute neutrophil count (ANC) ³ 1500/mm3, platelets ³ 100,000/mm3, hemoglobin \> 10.0 g/dL, serum creatinine greater than or equal to 1.5 times the upper limit of normal \[ULN\] or calculated creatinine clearance \> 50 mL/min, serum bilirubin greater than or equal to 2 times the ULN, alkaline phosphatase \< 3 times the ULN, and aspartate transferase (AST) and alanine transferase (ALT) greater than or equal to 3 times the ULN.

Prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR) that are within normal institutional limits.

Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization (applies to covered entities in the USA only) obtained from the subject prior to receipt of any study medication or beginning study procedures.
