Home > Press > Expansion of VivaGel US Trial and Completion of Enrollment in Herpes Trial

Abstract:
Starpharma Holdings Limited (ASX: SPL, OTCQX: SPHRY) today announced two updates in relation to its VivaGel (SPL7013 Gel) clinical development program:

Expansion of VivaGel US Trial and Completion of Enrollment in Herpes Trial

MELBOURNE, Australia | Posted on January 8th, 2008

• Study SPL7013-006: Protocol Amendment
An amendment is being made to the Phase I expanded safety study of VivaGel®, a vaginal microbicide that is being developed for prevention of HIV and genital herpes. The trial, which is being conducted in sexually active HIV-negative women in the USA, will add a third study group and enroll a total of 60 participants instead of 40.

The two existing trial groups are receiving either VivaGel® or its matching placebo gel. The third group of up to 20 women will receive a comparator placebo product widely used in other microbicide trials and known as the HEC(hydroxyethyl cellulose) "universal placebo." The third study group is being added and enrollment increased to provide more comprehensive data about the safety of these products that will strengthen the study conclusions.

The study is funded by the National Institute of Child Health and Human Development (NICHD) and the National Institute of Allergy and Infectious Disease (NIAID), components of the U.S. National Institutes of Health, and is being conducted by the Microbicide Trials Network (MTN) in collaboration with the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Starpharma and its study partners mutually agreed to amend the study following an interim review of data. Enrollment into the study has been paused to allow the study protocol to be amended and to allow additional training at the two trial sites in Tampa, Florida, and San Juan, Puerto Rico. Enrollment into the study is expected to re-commence within 1-3 months.

• Study SPL7013-004: Enrollment and Follow-up Completed
Enrollment and follow-up has been successfully completed and data analysis is currently underway in study SPL7013-004, another NIAID funded expanded safety study of VivaGel®. This was conducted in sexually abstinent women in San Francisco, California, USA, and Kisumu, Kenya. Results from this study are expected to be announced in quarter 1, 2008. During the trial, routine interim safety reviews identified no emergent pattern of product-related adverse events or participant withdrawals from the study.

About Starpharma Holdings Limited
Starpharma Holdings Limited (ASX:SPL, OTCQX:SPHRY) is a world leader in the development of dendrimer nanotechnology for pharmaceutical, life-science and other applications. SPL is principally composed of two operating companies, Starpharma Pty Ltd in Melbourne, Australia and Dendritic Nanotechnologies, Inc in Michigan, USA. Products based on SPL’s dendrimer technology are already on the market in the form of diagnostic elements and laboratory reagents.

The Company’s lead pharmaceutical development product is VivaGel® (SPL7013 Gel), a vaginal microbicide designed to prevent the transmission of STIs, including HIV and genital herpes.

In the wider pharmaceutical field Starpharma has specific programs in the areas of Drug Delivery and Drug Optimisation technologies (using dendrimers to control where and when drugs go when introduced to the body) and Targeted Diagnostics (using dendrimers as a scaffold to which both location-signalling and targeting groups are added to allow location of specific cell type, such as cancer cells). More broadly the company is exploring dendrimer opportunities in materials science with applications as diverse as adhesives, lubricants and water remediation.

The Company has recently made the following commercialisation announcements:
• February 2007 - Starpharma signed an agreement with EMD/Merck Biosciences for laboratory applications of Priofect™, an RNAi transfection reagent. Starpharma has retained all therapeutic applications of this siRNA delivery technology and is actively seeking partners to develop products based on it.

• July 2007 - Starpharma announced that it had signed an agreement with a leading condom company in relation to the use of VivaGel® as a condom coating. The agreement includes a program of evaluation and development and also commercialisation rights covering condoms with VivaGel® coatings within a specified geographical region.

• October 2007 - Starpharma announced the signing of an agreement with SSL International plc (LSE:SSL), the world’s largest manufacturer of condoms, and owner of Durex®, the world’s leading condom brand. The agreement, under which a commercial licence will be negotiated, sets out a co-development program for condoms with a VivaGel® coating.

• December 2007 - Starpharma announced the signing of a collaborative research agreement with Stiefel Laboratories, Inc., the world's largest independent pharmaceutical company specializing in dermatology, to apply Starpharma’s dendrimer nanotechnology to certain drugs used dermally. The collaboration will apply Starpharma’s dendrimer technology to deliver drugs through the skin with the aim of improving the effectiveness and tolerability of certain dermal treatments.

SPL has a comprehensive IP portfolio that comprises more than 224 patents/applications issued and pending across 56 patent families - a unique level of IP concentration among nanotechnology companies.

Dendrimers: A type of precisely-defined, branched nanoparticle. Dendrimers have applications in the medical, electronics, chemicals and materials industries.
