简要总结
This is a global, Phase 2, open label, dose selection, proof-of-concept study to assess progression free survival in subjects with metastatic melanoma.
Approximately 80 subjects at 29 sites in the U.S., U.K., Germany and Australia will be randomized into one of two dose groups: 2 mg/kg, 4 mg/kg. Weekly treatment will continue until disease progression.
Subjects must have measurable disease by CT Scan or MRI and must have completed at least one prior round of chemotherapy.
Subjects will be assessed for Efficacy, PK/PD, Overall survival, and Safety (Adverse Events/Adverse Events of Interest, Electrocardiograms (ECG's), clinical labs, physical exams/vital signs, tolerability).
详细描述
MORAb-004 is a monoclonal antibody directed against endosialin, a cell surface glycoprotein, which is expressed on cells involved in tumor vasculature. Studies have found endosialin to play a key role in tumor growth and neovessel formation in numerous cancer types including melanoma. Preclinical pharmacological studies have shown that MORAb-004 is a potentially useful anti-cancer agent. This clinical trial is being performed to determine the efficacy of MORAb-004 at two dose levels in subjects with metastatic melanoma, as well as to establish serum pharmacokinetics and pharmacodynamics of the antibody.

入选标准
- •Be surgically sterile or consent to use a medically acceptable method of contraception throughout the study period.
- •Histologically confirmed diagnosis of metastatic melanoma
- •At least 1 prior systemic treatment for metastatic melanoma with disease progression following treatment
- •Measurable disease, as defined by RECIST v1.1, assessed within 4 weeks prior to study entry
- •At least 3 week interval between first infusion of test article and most recent prior systemic anticancer therapy. All treatment-associated toxicity must be resolved to less than or equal to Grade 1 before the administration of MORAb-004

- •Clinically significant heart disease (Congestive heart failure of New York Heart Association [NYHA] Class 3 or 4, angina not well controlled by medication, or myocardial infarction within 6 mos.), or ECGs demonstrating clinically significant arrhythmias
- •Have any other serious systemic disease, including active bacterial or fungal infection, or any medical condition requiring cytotoxic therapy or chronic (at least 4 consecutive weeks) systemic corticosteroid use
- •Have active viral hepatitis or symptomatic Human immunodeficiency virus (HIV) infection
- •Be breast-feeding, pregnant, or likely to become pregnant during the study
- •Known allergic reaction to a prior monoclonal antibody therapy
- •Previous treatment with MORAb-004

结局指标
主要结局
Percentage of Participants With Progression-free Survival (PFS) at Week 24
时间窗: Week 24
PFS was defined as the time (in weeks) from the date of randomization to the date of the first sign of disease progression (PD) based on Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1, or date of death, regardless of cause. PD greater than or equal to (\>=) 20 percent (%) increase in the nadir of total tumor burden (TTB) (minimum 5 millimeter \[mm\]). Participants who were alive with no disease progression had their PFS time censored at the date of their last tumor assessment. Participants who received a new anti-cancer therapy before disease progression had their PFS time censored at the date of their last tumor assessment before the new anti-cancer therapy was started. PFS was analyzed using Kaplan Meier method.
次要结局
- Overall Survival (OS)(Date of first study treatment (Day 1) to date of death or up to approximately 2 years 7 months)
- Percentage of Participants With PFS at Weeks 16 and 52(Week 16 and Week 52)
- Percentage of Participants With Overall Response(Date of first study treatment (Day 1) to complete response or partial response, assessed up to approximately 2 years 7 months)
- Optimal Biologic Dosing (OBD) of Morab-004(Day 1 Cycle 1 (Cycle length = 28 days))
