Pfizer, Adolor partner to develop new pain treatments
NEW YORK and EXTON, Pa Pfizer and Adolor have joined together in a worldwide collaboration to develop and commercialize two novel compounds, ADL5859 and ADL5747, for the treatment of pain. The compounds are Delta opioids that can treat a wide range of inflammatory, neuorpathic and acute pain conditions. Delta receptors have the potential to modulate pain.
The companies will form a Joint Steering Committee to guide the development and commercialization of products resulting from the collaboration. Pfizer will be responsible for securing regulatory approvals and commercialization on a worldwide basis.
The terms of the agreement provide for Pfizer and Adolor to share revenues and expenses 60/40 percent in the U.S. Adolor will receive an upfront, non-refundable payment of $30 million, plus $1.9 million reimbursement for prior Phase 2 development costs. Adolor may also receive payments of up to $232.5 million upon the achievement of development and regulatory milestones for its Delta compounds. More than 50 percent of these milestones may be earned prior to regulatory approval of the compounds, with the first milestone payment available to be earned on commencement of Phase 2b clinical studies.
ADL5859 is in a Phase 2 development program exploring its analgesic efficacy in inflammatory pain associated with rheumatoid arthritis and acute post-dental surgery pain. Additional programs are planned to evaluate ADL5859 in patients with diabetic peripheral neuropathy and osteoarthritis. All future development work is subject to a Joint Development Committee. Adolor expects to begin Phase 1 clinical testing of ADL5747 in the first quarter of 2008.
Wyeth and GSK may see competition in pediatric vaccines
LONDON There may be a clash of the titans underway.
Pharma giants Wyeth and GlaxoSmithKline are set to go head to head with their competing childhood vaccines, but Wyeth dismissed any worries about the newcomer to the vaccine playground.
Wyeth’s Prevnar will remain a key sales driver for the company but would not be hindered by Glaxo’s Synflorix, said Emilio Emini, the U.S. group’s head of vaccine research and development, on Tuesday.
Prevnar, a vaccine for infants and children to prevent certain invasive pneumococcal diseases, is active against seven types of streptococcus pneumonia, which together account for some 80 percent of illnesses, Reuters reported Tuesday.
Glaxo’s Synflorix, which a company spokeswoman said remained on track for submission to European regulators by the end of 2007, targets 10 types, and even prevents inflammation of the middle ear.
But Emini said Synflorix was incomparable to the new version of Prevnar.
“Essentially, it is a direct equivalent of the original Prevnar,” he said in an interview with Reuters on the sidelines of the FT Global Pharmaceutical and Biotechnology Conference. “If you look at the residual 20 percent of disease (not addressed by Prevnar) and ask how much is covered by the GSK 10-valent vaccine, it’s actually a small percentage. How much is covered by Prevnar-13? It’s over 60 percent,” Emini said.
Wyeth intends to submit a new version of Prevnar, active against 13 strains, to both European and U.S. regulators by the beginning of 2009.
The original version of the vaccine was introduced in 2000. Third-quarter sales of Prevnar were up 24 percent from a year earlier at $634 million.
Biomira to make move to U.S. under new name
EDMONTON, Canada Biomira shareholders have approved a plan to move the company to the U.S. and to change its name to Oncothyreon Incorporated. Oncothyreon will be the parent corporation of a successor company of Biomira and its subsidiaries, according to Canada.com.
The biotech company, which focuses on cancer treatment, currently has a few drugs in its pipeline including Stimuvax, which it is developing with Merck to treat non-small cell lung cancer. That drug is currently in a Phase III clinical trial. The next drug that is furthest along in development is a small molecule called PX-12, which is a drug used to treat pancreatic cancer and is currently in a Phase II trial.
“We are very pleased to have received the strong support of our shareholders for our relocation and the revision of our capital structure,” chief executive officer Robert Kirkland said. The shareholders will receive one-sixth of a share of common stock of Oncothyreon in exchange for each Biomira share. The new company will be based in Seattle.
