Tibotec announced today that it has reached agreement with the Global Alliance for TB Drug Development that will give the alliance a global royalty-free licence to develop Tibotec’s new TB drug TMC-207 for first-line treatment in people with drug-susceptible TB. Tibotec and the TB Alliance will share future development costs.

TMC-207 is the first TB drug with a new mode of action to be developed in over 40 years, and scientists are hopeful that results of studies in drug-resistant patients indicate potential to dramatically shorten the current six- to eight-month course of TB treatment needed in people with drug-susceptible TB.

Tibotec will continue to develop and retain the marketing rights for TMC-207 in drug-resistant TB. The company is currently conducting a phase II study of the drug; an eight-week interim analysis published earlier this month showed that patients who received TMC-207 in addition to standard treatment for multi-drug resistant TB were significantly more likely to be sputum smear-negative at week eight.

Glossary

microbicide

A product (such as a gel or cream) that is being tested in HIV prevention research. It could be applied topically to genital surfaces to prevent or reduce the transmission of HIV during sexual intercourse. Microbicides might also take other forms, including films, suppositories, and slow-releasing sponges or vaginal rings.

strain

A variant characterised by a specific genotype.

 

sputum smear

A diagnostic test in which a sample of spit is examined under the microscope for the presence of micro-organisms.

 

first-line therapy

The regimen used when starting treatment for the first time.

cervix

The cervix is the neck of the womb, at the top of the vagina. This tight ‘collar’ of tissue closes off the womb except during childbirth. Cancerous changes are most likely in the transformation zone where the vaginal epithelium (lining) and the lining of the womb meet.

Tibotec says that when the drug is licensed for use in MDR-TB it will establish an access programme to ensure that the drug is available and affordable in developing countries.

Tibotec will also continue to look for new compounds to treat TB, and under the terms of the agreement will provide them on a royalty-free basis to the TB Alliance for future development.

The TB Alliance is a not-for-profit, product development partnership accelerating the discovery and development of new TB drugs that will shorten treatment, be effective against susceptible and resistant strains, be compatible with antiretroviral therapies for those HIV-TB patients currently on such therapies, and improve treatment of latent infection.

The TB Alliance operates with funding from the Bill & Melinda Gates Foundation, the Netherlands Ministry of Foreign Affairs (DGIS), the United Kingdom Department for International Development (DfID), and the United States Agency for International Development (USAID).

Tibotec’s partnership with the TB Alliance indicates the future course the company will take in developing drugs for neglected diseases of the developing world. Ben Plumley, Vice President of Global Access and Partnerships at Tibotec said, “The future of successfully tackling neglected diseases, such as TB, will be through joint development initiatives between companies and product development partnerships, such as the one we are announcing today with the TB Alliance.”

The company is also working with another public-private partnership, the International Partnership for Microbicides, to develop a vaginal microbicide containing the company’s antiretroviral drug dapivirine, together with a novel cervical ring that will allow the microbicide to remain active for long periods.
