|Brief Title ICMJE||A Phase I Study of MGAH22 in Patients With Refractory HER2 Positive Cancers|
|Official Title ICMJE||A Phase 1, Dose Escalation Study of MGAH22 (Fc-Optimized Chimeric Anti-HER2 Monoclonal Antibody) in Patients With Refractory HER2 Positive Breast Cancer and Patients With Other HER2 Positive Carcinomas for Whom no Standard Therapy is Available|
- MGAH22 is an experimental drug that has been designed to target cancer cells that make too much of a protein called human epidermal growth factor receptor 2 (HER2). Too much of this protein can turn a normal cell into a cancer cell and cause the cancer to grow faster. Some treatments have been successful at targeting HER2-positive cancer cells, particularly HER2-positive breast cancer, but these treatments have not been as effective for other types of HER2-positive cancers. MGAH22 is being tested to see if it is a safe and effective potential treatment for HER2-positive cancers that have not responded to standard treatments.
- To evaluate the safety and effectiveness of MGAH22 in treating HER2-positive cancers that have not responded to standard treatments.
- Individuals at least 18 years of age who have been diagnosed with HER2-positive breast cancer or other HER2-positive cancers (such as bladder, ovarian, lung, and prostate cancer) that have not responded to standard treatments.
Because the higher affinity alleles of CD16A and CD32A are less frequent in the population than the lower affinity alleles, these observations suggest that anti-HER2 antibodies, such as MGAH22, engineered to have increased affinity for the activating Fc receptors and in particular the low binding alleles of the activating Fc receptors may have increased clinical activity and should be pursued.
-To determine the toxicity profile of four once-weekly intravenous (IV) doses of MGAH22.
