Genetix Pharmaceuticals has announced that the company’s clinical program to treat Adrenoleukodystrophy (ALD). The company is developing a gene therapy product in collaboration with Professor Patrick Aubourg and Doctor Nathalie Cartier of the National Institute of Health and Medical Research (INSERM).

Genetix is planning to file an IND to expand the development in the US, as well as to expand the ongoing trial in France. The current development timeline should make the product commercially available to patients by 2014. Patrick Aubourg and Nathalie Cartier will become scientific advisors to Genetix’s ALD clinical programs.

ALD is a devastating disease that afflicts 1/17,000 males with onset of severe cognitive and neurologic deficits between the ages of 5 and 12, or in adulthood. It progresses to death within 3-10 years of diagnosis. Many people became familiar with ALD from the 1992 movie Lorenzo's Oil, which featured a young boy affected with this disease.

Patrick Aubourg, M.D. of Inserm-University Paris Descartes commented, “We are delighted to develop this ground breaking gene therapy product together with Genetix, the leading gene therapy company. Our future close scientific collaboration is off to a good start. Production of large GMP batches is underway, which will allow us to rapidly treat the rest of the patients in this clinical trial. We look forward to working with Genetix to expand the trials and acquire the pivotal data and regulatory approvals needed to bring this product to market.”

Gene therapy places a healthy gene into the patients’ own bone marrow stem cells. In the first two patients described in the November issue of Science, the disease has been stabilized.

Genetix’s gene therapy approach has the following advantages over allogeneic bone marrow transplantation:

• Applicable to all patients and no limitation to have a matched donor;
• No risk of death from Graft Versus Host Disease by using patients’ own cells;
• More rapid engraftment/reconstitution of marrow and immune function post transplant due to perfect match between patients’ stem cells and marrow mileu.

To date, in both patients treated, the therapy has been safe and efficacious. As with all drugs in development, the ongoing clinical trials are designed to statistically prove safety and efficacy for regulatory approval.

Alfred Slanetz, Chief Executive Officer of Genetix, commented, “We congratulate our colleagues and collaborators at INSERM on their publication and accomplishments. Today two of two treated children with ALD, who otherwise would be severely cognitively impaired and on a road to death, are able to live healthy and normal lives because of the ALD lentiviral gene therapy. Developing safe and effective treatments for incurable diseases is what our industry is all about. Genetix is now committed to developing this product in the most scientific and ethical way, and to make this product commercially available to all patients afflicted with this devastating disease.”
