BioMarin Pharmaceutical

History

BioMarin was founded in 1997 by Christopher Starr Ph.D. and Grant W. Denison Jr. with an investment of a $1.5 million from Glyko Biomedical and went public in 1999. Seed investors were amongst others MPM Bioventures, Grosvenor Fund and Florian Schönharting.

Business development

In 2002, BioMarin acquired Glyko Biomedical.

In 2009, BioMarin acquired Huxley Pharmaceuticals, Inc. (Huxley), which had rights to a proprietary form of 3,4-diaminopyridine (3,4-DAP), Amifampridine phosphate. In 2010, BioMarin was granted marketing approval by the European Commission for 3,4-diaminopyridine (3,4-DAP), amifampridine phosphate for the treatment of the rare autoimmune disease Lambert-Eaton myasthenic syndrome (LEMS). BioMarin launched the product under the name Firdapse.

In 2010, BioMarin acquired LEAD Therapeutics, Inc. (LEAD), a small private drug discovery and early stage development company with key compound LT-673, an orally available poly (ADP-ribose) polymerase (PARP) inhibitor studied for the treatment of patients with rare, genetically defined cancers. This acquisition was followed by the purchase of ZyStor Therapeutics, Inc. (ZyStor), a privately held biotechnology company developing ERTs for the treatment of lysosomal storage disorders and its lead product candidate, ZC-701, a fusion of insulin-like growth factor 2 and alpha glucosidase (IGF2-GAA) in development for Pompe disease. At its R&D day in October 2010, BioMarin also announced a new program for a peptide therapeutic, vosoritide (BMN-111), for the treatment of achondroplasia.

In 2012, BioMarin acquired Zacharon Pharmaceuticals, a private biotechnology company based in San Diego focused on developing small molecules targeting pathways of glycan metabolism.

In 2014, BioMarin acquired a histone deacetylase inhibitor chemical library from Repligen for $2 million with the intention of advancing work toward therapies for Friedreich's ataxia and other neurological disorders.

In November 2014, the company agreed the acquisition of Prosensa for up to $840 million, the range of treatments for Duchenne muscular dystrophy however failed to attain FDA approval and in May 2016 development ceased.

Products

As of 2016, BioMarin has five products on the market, each of which is an orphan drug.

Controversies

In 2010, BioMarin became involved in controversy surrounding 3,4-diaminopyridine (3,4-DAP). BioMarin markets a phosphate salt of 3,4-DAP under the name Firdapse. In 2010, BioMarin was granted exclusive licensing rights to Firdapse for 10 years. As a result, the price of a prescribed National Health Service treatment course has increased from $1,987 for the unlicensed drug to $69,970 for Firdapse. The company states that prior to its licensing, there was no guaranteed quality control of the product and no way of formally monitoring for uncommon side effects through the regulatory process.

In 2013, BioMarin Pharmaceuticals was at the center of a high profile debate regarding expanded access of cancer patients to experimental drugs. On the advice of her doctor, Andrea Sloan, a patient with advanced ovarian cancer, requested that the company provide her with access to BMN 673, an unapproved PARP inhibitor drug candidate that had exhibited promising activity in a small Phase 1 clinical trial. The company declined, citing safety concerns. Ms. Sloan eventually received a similar drug candidate from a different company.

In 2015, there was another controversy over expanded access, concerning the supply of a drug on clinical trial to a German child who was suffering from a brain disorder but who was not part of the trial.
