MannKind Corporation Announces Clearance Of IND For MKC1106-PP Immunotherapy In Solid Malignancies

VALENCIA, Calif., Nov. 27 /PRNewswire-FirstCall/ -- MannKind Corporation , focused on discovering, developing and commercializing treatments for diabetes and cancer, announced today that its Investigational New Drug (IND) application for MKC1106-PP Immunotherapy in Solid Malignancies, has now been cleared by the U.S. Food and Drug Administration (FDA). The clearance of the IND means that the Company may now proceed with the initiation of its Phase 1 clinical trial -- a multicenter, open label, clinical trial of immune response, safety and tolerability of a DNA vector with two synthetic peptides in subjects with solid malignancies, in a plasmid prime-peptide boost treatment. The clinical study is designed to target two tumor-specific antigens, preferential antigen of melanoma (PRAME) and prostate specific membrane antigen (PSMA), on the basis of their level of expression in commonly occurring adult malignancies, such as ovarian, prostate, renal, pancreatic, breast, colon carcinoma and melanoma. Enrollment of the first patient is expected before the end of the year.

“With FDA clearance, we are now able to initiate our first Phase 1 clinical trial of our cancer immunotherapy program. This is a significant and exciting milestone in our efforts to build an immunotherapy franchise in MannKind,” said Alfred Mann, Chairman and Chief Executive Officer of MannKind Corporation. “We continue our progress toward building our product pipeline and demonstrating our commitment to providing therapeutic products for diabetes and cancer.”
