  • Pfenex’s commercial partner Adalvo entered into commercialization agreement in Latin America for PF708 with a large, multinational pharmaceutical firm

  • Serum Institute of India is awarded first UNICEF supply agreement for Pneumosil®

  • Merck announces safety and immunogenicity objectives were met in two initial Phase 3 studies for its MRK-V114 Pneumococcal Conjugate Vaccine candidate

SAN DIEGO, June 26, 2020 (GLOBE NEWSWIRE) -- Pfenex Inc. (NYSE American: PFNX) announced today the achievement of several significant milestones across their business portfolio. Theramex, the European commercialization partner for Pfenex and Adalvo (formerly Alvogen B2B), received a positive opinion for PF708 (branded in Europe as Livogiva™) from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA).  Additionally, Adalvo recently entered into a commercialization agreement with a multinational pharmaceutical company to commercialize PF708, upon receipt of marketing authorization, in certain countries in Latin America.

Merck recently announced that V114, its investigational 15-valent pneumococcal conjugate vaccine met safety and immunogenicity objectives in initial Phase 3 studies in adults. Also, Serum Institute of India announced its first supply agreement with UNICEF for Pneumosil™, a 10-valent pneumococcal vaccine developed to address pneumococcal infection in low- and middle-income countries.  Both V114 and Pneumosil contain CRM197 produced via license agreements to the Pfenex Expression Technology, pursuant to which Pfenex may earn development milestone payments and royalties on net product sales.

“This is an exciting time for Pfenex as we continue to achieve meaningful clinical, regulatory and commercial milestones across our pipeline, highlighted today by the positive opinion on Livogiva from the CHMP and the announcement of positive results in two of Merck’s Phase 3 studies for the Merck V114 vaccine,” said Pfenex CEO Eef Schimmelpennink. “Over the past few years, we have had a relentless, laser like focus on our core portfolio and we believe those efforts are paying off.”

“With Alvogen’s U.S. launch of Teriparatide Injection and Serum Institute of India’s Pneumosil supply agreement with UNICEF, we now have two royalty bearing commercial products, a critical milestone as we continue our transition towards novel biopharmaceutical development,” said Mr. Schimmelpennink.

Earlier today, StreetAccount issued a release that erroneously described Livogiva as a Teva product.  In order to address this incorrect information, Pfenex asked the NYSE to temporarily halt trading in Pfenex’s stock. 

PF708: CHMP Positive Opinion & Latin America Commercial Partner

The Committee for Medicinal Products for Human Use has adopted a positive opinion recommending marketing authorization for PF708, which will be branded in Europe as Livogiva™ (teriparatide injection), a biosimilar product candidate to the reference medicine Forsteo® (teriparatide injection) indicated for uses including in postmenopausal women with osteoporosis who are at high risk for having bone fractures. The CHMP’s recommendation will now be considered by the European Commission, which typically issues a decision within 67 days of CHMP’s recommendation.

If the European Commission affirms the CHMP opinion, it will grant a marketing authorization with unified labeling that is valid in the more than 25 countries that are members of the European Union, as well as European Economic Area members, Iceland, Liechtenstein and Norway. The version of Livogiva that is approved for marketing in the United States is Teriparatide Injection (previously referred to as PF708, as well as Bonsity), which the U.S. Food and Drug Administration (FDA) continues to evaluate for therapeutic equivalence to its reference drug Forteo®.

In addition, Pfenex announced Adalvo has partnered with a large, multinational pharmaceutical firm to commercialize PF708, upon receipt of marketing authorization, in Brazil, Columbia, Mexico, Ecuador, Paraguay, and Peru in Latin America.

“The CHMP positive opinion on Livogiva and the addition of a global, distinguished partner in Latin America are each important steps in our global regulatory and commercial plans that aim to provide a teriparatide product to patients in European and Latin American markets in a cost effective manner,” said Faysal Kalmoua, Alvogen’s Executive Vice President of Portfolio.

Merck also announced its plans to continue to work with the FDA and other regulatory authorities around the world on filing plans for licensure of this vaccine as additional data from the Phase 3 program become available.  Merck currently has a license to the Pfenex Expression Technology for the production of the carrier protein CRM197 a key component of the V114 vaccine.
