NEW YORK and MIAMI, Sept. 24, 2021 (GLOBE NEWSWIRE) -- Pfizer Inc. (NYSE: PFE) and OPKO Health Inc. (NASDAQ: OPK) announced today that the U.S. Food and Drug Administration (FDA) has extended the review period for the Biologics License Application (BLA) for somatrogon, a once-weekly long-acting recombinant human growth hormone, for the treatment of growth hormone deficiency (GHD) in pediatric patients. The Prescription Drug User Fee Act (PDUFA) goal date has been extended by three months to January 2022, as a result of Pfizer’s submission of additional data to the original BLA.
In 2014, Pfizer and OPKO entered into a worldwide agreement for the development and commercialization of somatrogon for the treatment of GHD. Under the agreement, OPKO is responsible for conducting the clinical program and Pfizer is responsible for registering and commercializing the product for GHD.
Somatrogon is an investigational biologic product that is glycosylated and comprises the amino acid sequence of human growth hormone and one copy of the C-terminal peptide (CTP) from the beta chain of human chorionic gonadotropin (hCG) at the N-terminus and two copies of CTP (in tandem) at the C-terminus. The glycosylation and CTP domains account for the half-life of the molecule. Somatrogon has received Orphan Drug designation in the U.S. and the EU for the treatment of children and adults with growth hormone deficiency.
About Growth Hormone Deficiency
Growth hormone deficiency is a rare disease characterized by the inadequate secretion of growth hormone from the pituitary gland and affects one in approximately 4,000 to 10,000 children.1,2 In children, this disease can be caused by genetic mutations or acquired after birth.1,3 Because the patient's pituitary gland secretes inadequate levels of somatropin, the hormone that causes growth, a child’s height may be affected and puberty may be delayed.1,3,4 Without treatment, affected children will have persistent growth attenuation and a very short height in adulthood.3,4 Children may also experience other problems with physical health and mental well-being.3,4

This release contains forward-looking information about an investigational growth hormone deficiency therapy, somatrogon, including a potential indication in the U.S. for once-weekly treatment of pediatric patients with growth hormone deficiency, including its potential benefits, that involves substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Risks and uncertainties include, among other things, the uncertainties inherent in research and development, including the ability to meet anticipated clinical endpoints, commencement and/or completion dates for our clinical trials, regulatory submission dates, regulatory approval dates and/or launch dates, as well as the possibility of unfavorable new clinical data and further analyses of existing clinical data; the risk that clinical trial data are subject to differing interpretations and assessments by regulatory authorities; whether regulatory authorities will be satisfied with the design of and results from our clinical studies; whether and when drug applications may be filed in any additional jurisdictions for somatrogon for the treatment of pediatric patients with growth hormone deficiency or in any jurisdictions for any other potential indications for somatrogon; whether and when the FDA may approve the BLA for somatrogon for the treatment of pediatric patients with growth hormone deficiency and whether and when regulatory authorities in any jurisdictions may approve any such other applications that may be pending or filed (including the applications filed in the EU and Japan), which will depend on myriad factors, including making a determination as to whether the product's benefits outweigh its known risks and determination of the product's efficacy and, if approved, whether somatrogon will be commercially successful; decisions by regulatory authorities impacting labeling, manufacturing processes, safety and/or other matters that could affect the availability or commercial potential of somatrogon; uncertainties regarding the impact of COVID-19 on Pfizer’s and OPKO’s business, operations and financial results; and competitive developments.
