Peregrine Pharmaceuticals, Inc. is a publicly-traded American biopharmaceutical company with a portfolio of monoclonal antibodies in clinical trials as potential cancer treatments and diagnostic agents. As of 2016 their lead product candidate was bavituximab. It also has a revenue-generating subsidiary, Avid Bioservices, which is a contract manufacturing organization that provides services to Peregrine and to other companies.

History

Peregrine was founded in 1981.[1]

In 2002 Peregrine established a wholly owned subsidiary, Avid Bioservices, a contract manufacturing organization that provides cGMP development and biomanufacturing services for both Peregrine and outside customers.[2] In 2015 Avid had revenues of about $27 million, about 80% of which came under contract from Halozyme Therapeutics.[1]

Products in development

Bavituximab

Bavituximab (PGN401) is a human-mouse chimeric monoclonal antibody against phosphatidylserine, which is a component of cell membranes that is exposed when a cell is transformed into solid tumor cancer cell or dies,[3][4] and when cells are infected with hepatitis C.[5] The process of cell death is highly controlled and so there usually no immune response to phosphatidylserine but when bavituximab binds to it, the conjugate appears to stimulate an immune response in humans.[4]

Bavituximab was invented at University of Texas Southwestern Medical Center at Dallas; Peregrine exclusively licensed intellectual property related to bavituximab from the university, including US patent 6,300,308 invented by Alan J. Schroit and US Patents 6,406,693 and 6,312,694 invented in the laboratory Philip E. Thorpe.[1]:6[6]

In June 2014 the FDA granted Peregrine fast-track status as a second-line drug candidate for non-small cell lung cancer.[7]

As of January 2016, bavituximab had been in a Phase III clinical trial for non-small cell lung cancer, a Phase II/III trial for breast cancer, a Phase II trial for pancreatic cancer, a phase I/II trial for hepatocellular carcinoma, and Phase I clinical trials in malignant melanoma and rectal cancer; its development had been discontinued for influenza and prostate cancer.[3] As of 2011 it had been in a Phase II trial for hepatitis C[5] but no results had been reported as of 2016.[3]

124I-PGN650

Example image from preclinical studies

124I-PGN650 is a phosphatidylserine-targeting F(ab')2 fully human monoclonal antibody fragment joined to the PET imaging radio-isotope iodine-124 being developed to obtain medical images of cancer.[8]

Cotara

Cotara (131I-chTNT-1/B) is a chimeric monoclonal antibody against DNA-histone H1 complex called TNT-1, conjugated to the radioisotope iodine-131.[9][10] As of 2016 Peregrine was developing it for Glioblastoma multiforme; it has been granted orphan status in Europe and the US.[10]
