Form 8-K for CATALYST PHARMACEUTICAL PARTNERS, INC.


31-Oct-2012

Entry into a Material Definitive Agreement, Unregistered S


Item 1.01 Entry Into a Material Definitive Agreement

On October 26, 2012, Catalyst Pharmaceutical Partners, Inc. (the "Company") entered into a strategic collaboration with BioMarin Pharmaceutical Inc. ("BioMarin") for Firdapse™ ("Firdapse™ or the "Product"), a Phase III orphan drug for the treatment of Lambert-Eaton Myasthenic Syndrome ("LEMS"), which is a rare, debilitating and sometimes fatal autoimmune disease with the primary symptoms of muscle weakness. The key components of the collaboration include Catalyst licensing the exclusive North American rights to the Product pursuant to the terms of a License Agreement, dated as of October 26, 2012, between the Company and BioMarin (the "License Agreement") and BioMarin making a $5,000,000 investment in the Company pursuant to the terms of a Convertible Promissory Note and Note Purchase Agreement, dated as of October 26, 2012, between the Company and BioMarin (the "Investment Agreement") to rapidly advance the development of Firdapse™ in the United States.

Investment Agreement

On October 26, 2012, the Company and BioMarin entered into the Investment Agreement pursuant to which BioMarin has invested $5,000,000 into the Company. Initially, such amount shall be treated as a loan to the Company. However, the amount of the loan shall automatically convert into shares of the Company's authorized but unissued common stock on the earlier of: (i) March 31, 2013, or
(ii) the date that is thirty (30) days after the Company publicly releases top-line data from its Phase II(b) clinical trial evaluating the use of its product candidate, CPP-109, for the treatment of cocaine addiction (the "Conversion Date"), except in certain limited circumstances as more particularly described below and in the Investment Agreement. As previously reported, the Company currently expects to be in a position to release the top-line data from its Phase II(b) clinical trial during the first half of November 2012. The conversion price of the shares of the Company's common stock to be acquired by BioMarin upon conversion of its $5 million investment in the Company will be the "dollar weighted average price" (as defined in the Investment Agreement) of the Company's common stock for the fifteen (15) business day period prior to the Conversion Date, multiplied by 0.9, provided, however, that the conversion price shall not be less than $0.75 per share or more than $2.50 per share.

The Investment Agreement also provides that the Company will use the $5 million solely for the purpose of developing the Product and that for such period that BioMarin owns more than 10% of the Company's outstanding common stock, BioMarin will exclusively use the exemption from registration provided under Rule 144 to make sales of the Company shares acquired in the investment transaction. The Company also agreed in the Investment Agreement not to make certain asset sales or sales of the Company's securities during the period between the date of the Investment Agreement and the Conversion Date without the prior written consent of BioMarin. Finally, the Investment Agreement provides that the Company is obligated to repay the $5 million to BioMarin, with interest, if an "event of default" (as defined in the Investment Agreement) occurs prior to the conversion of the loan amount into shares of the Company's common stock.

The foregoing description of the Investment Agreement is qualified in its entirety by reference thereto. A copy of the Investment Agreement is Exhibit 10.1 to this Current Report on Form 8-K, and is incorporated fully herein by this reference.


The Product and Development Plans for the Product in the United States

Firdapse™ is a proprietary form of 3,4-diaminopyridine (amifampridine phosphate), or 3,4-DAP, for the treatment of LEMS. BioMarin acquired the rights to Firdapse™ in October 2009 as a result of its acquisition of Huxley Pharmaceuticals, Inc. ("Huxley"). Firdapse™ was granted marketing approval in the European Union ("EU") in December 2009, which, because Firdapse™ had previously been granted orphan medicinal product designation in the EU, included ten year marketing exclusivity in the EU. BioMarin will continue to sell Firdapse™ in the EU following this transaction.

Pursuant to the License Agreement, the Company will license the rights to Firdapse™ in North America. At present, BioMarin is conducting a Phase III clinical trial of Firdapse™ (the "Phase III Trial"), which trial will be transferred to and continued by the Company pursuant to the License Agreement. The Phase III Trial began in the second quarter of 2011 and is a double-blind, placebo-controlled randomized discontinuation study followed by an open-label extension period in approximately 30 patients across 10 sites in the U.S. and Europe. The primary objective of the trial is to evaluate the efficacy and safety, including the long-term safety, of Firdapse™. The primary endpoint is a change from baseline in the Quantitative Myasthenia Gravis score at 14 days and the secondary endpoint is change from baseline in the timed 25-foot walk test at 14 days. At present, the Company expects to complete the double-blind treatment portion of the Phase III trial in the second half of 2014.

The U.S. Food and Drug Administration ("FDA") has previously granted orphan drug designation to Firdapse™ for the treatment of LEMS, which means that if the Company is the first to obtain approval of the Product in the United States, it will be eligible to obtain seven year marketing exclusivity in the United States.

LEMS is a rare autoimmune disease with the primary symptoms of muscle weakness. The muscle weakness in LEMS is caused by autoantibodies to voltage gated calcium channels leading to a reduction in the amount of acetylcholine released from nerve terminals. The prevalence of LEMS is estimated at approximately 3,000 patients in the United States and Canada. Approximately 50 percent of LEMS patients diagnosed have small cell lung cancer. Patients with LEMS typically present with fatigue, muscle pain and stiffness. The weakness is generally more marked in the proximal muscles, particularly of the legs and trunk. Other problems include reduced reflexes, drooping of the eyelids, facial weakness and problems with swallowing. Patients often report dry mouth, impotence, constipation and feelings of light headedness on standing. These problems can be life threatening when the weakness involves respiratory muscles. A diagnosis of LEMS is generally made on the basis of clinical symptoms, electromyographic testing and the presence of autoantibodies against voltage gated calcium channels.

There are no approved drugs in the United States for the treatment of LEMS. Current options rely on intravenous immunoglobulin, plasmapheresis and/or immuno suppressant drugs. Firdapse™ is the only version of amifampridine phosphate . . .
