Interim Review of Phase II Trial for Alopecia

Phytopharm PLC 6 January 2000 Phytopharm plc announces interim review of Phase II trial for Alopecia Phytopharm plc (PYM: London Stock Exchange) ('Phytopharm') announced today that it has conducted an interim review of its Phase II clinical trial of P45, its patented topical cream for the treatment of androgenetic alopecia (male pattern baldness). In this study, patients are being treated with either P45 or an inert placebo for 52 weeks. Using a double blind trial design, 69 patients have been randomly assigned to receive either P45 or placebo cream. Neither the patients, the investigating physicians nor Phytopharm are aware of which subjects are using the active material. The purpose of the review was to examine the safety and conduct of the study using blinded data collected from all patients after 20 weeks of treatment. With regard to the conduct of the study, recruitment has been satisfactory and is now complete. The safety data have revealed no treatment related serious adverse events, and the emergent safety profile warrants the continuation of the study. All patients are due to complete treatment during Q3 2000. An analysis of the full data set is expected to be available in Q4 2000. Data have been collected on the investigators' and patients' assessments of hair growth and scalp condition. Photographic records have also been generated. There are apparent differences between the groups according to the various safety and efficacy parameters. However, these data collected at the mid point of the study are preliminary and blinded with respect to the treatment and placebo groups. Dr. Richard Dixey, Chief Executive of Phytopharm, said: 'This study is proceeding satisfactorily but we cannot unblind the data without invalidating the final result. We must await the full analysis of the unblinded data at the end of the 52 week treatment period before any conclusions can be drawn.'

The US Food and Drug Administration call such medicinal products 'botanicals'. Botanical products are whole or partially purified extracts of medicinal plants in which the chemical composition is not fully characterised. These products represent a new sector in the pharmaceutical market. Phytopharm is the leading company in the development of botanical pharmaceuticals. It has developed a portfolio of 11 such products, nine of which are in the clinical evaluation phase. These products have been targeted in the five therapeutic categories of anti-inflammatory treatments, neurological disorders, dermatology, cancer and metabolic diseases. In 1997, Phytopharm was granted an Investigational New Drug (IND) approval in the US, the first time an IND has been granted for a complex botanical product, indicating that such products may be registered as prescription medicines.
