Press release from Incyte
Incyte to Report Positive Preliminary Clinical Results from HIV and Diabetes Programs and Highlight Progress in Several Drug Development Programs at the 25th JPMorgan Healthcare Conference
WILMINGTON, Del.--(BUSINESS WIRE)--Jan 8, 2007 - Incyte Corporation (Nasdaq: INCY) will announce today at the 25th Annual JPMorgan Healthcare Conference positive preliminary results from a Phase IIa placebo-controlled trial designed to evaluate the anti-viral effects and safety of INCB9471, Incyte's lead CCR5 antagonist that is being developed as a once-a-day oral treatment for patients with human immunodeficiency virus (HIV) infections. In the first seven treated patients the compound was well tolerated over the 14-day trial period with a 1.7 log10 viral load drop at day 14. Consistent with the compound's long half-life of 60 hours, viral replication continued to be suppressed after the last dose with a nadir in viral load reduction of 2.1 log10 seen at day 20.
Incyte will also announce today preliminary proof-of-principle results from a Phase IIa trial for INCB13739, its oral inhibitor of 11-beta hydroxysteroid dehydrogenase type 1 (11beta-HSD1) that is being developed as a treatment for type 2 diabetes. While this trial is still ongoing, in the six treated obese insulin resistant individuals who have completed the trial, a single dose of INCB13739 completely inhibited 11beta-HSD1 activity in both adipose tissue and liver - Incyte believes this is the first time such results have been reported for any 11beta-HSD1 inhibitor in man.
The ability to fully inhibit 11beta-HSD1 in these tissues, which are major contributors to the body's control of glucose metabolism, shows that INCB13739 has the necessary properties to demonstrate the potential therapeutic effect of 11beta-HSD1 inhibition in type 2 diabetes and related cardiovascular risk factors.
Incyte intends to submit for presentation, at appropriate scientific meetings, the full results from these two studies.
In his presentation at the JPMorgan Conference, Dr. Friedman will also describe progress in several of the company's drug development programs, including:
-- The initiation of a Phase I trial for a follow-on CCR5 antagonist, INCB15050, a potential once-a-day therapy for use in HIV-infected patients. This study is expected to complete in the first quarter of this year.
-- The filing of an Investigational New Drug Application (IND) for its lead CCR2 antagonist, INCB8696, which Incyte intends to develop first as an oral treatment for multiple sclerosis. Incyte may also pursue a second indication, lupus nephritis, and potentially other autoimmune nephritides. The Phase I trial is expected to initiate in the first quarter of this year.
-- The announcement of several new programs in inflammation and oncology involving oral inhibitors of the janus-associated kinases (JAKs). There are four JAK enzymes, JAK1, JAK2, JAK3 and TKY2, which are an essential part of the intracellular signaling mechanisms used by a number of cytokines and growth factors. Incyte has identified a range of potent, moderately selective, oral JAK2 inhibitors from multiple chemical scaffolds. A number of these compounds are expected to enter clinical trials beginning in the first quarter of this year.
"The JAK2 program has the potential to significantly expand our pipeline in areas that we can pursue on our own. We expect to file INDs for several indications beginning this quarter and to have proof-of-concept data for at least one of these before year-end," stated Dr. Friedman.
New JAK2 Program Has Therapeutic Potential in Multiple Disease Areas
Incyte's focus on developing oral JAK2 inhibitors is based on a growing body of clinical data suggesting that blocking signaling through the JAK2 pathway has therapeutic potential in a number of inflammatory and myeloproliferative diseases, and potentially other cancers. Clinical studies of monoclonal antibodies that inhibit cytokines which signal through JAK2, as well as with a moderately selective oral JAK3 inhibitor that also inhibits JAK2, have shown impressive clinical efficacy in rheumatoid arthritis and psoriasis, suggesting that the JAK2 pathway plays a pivotal role in inflammation. Given the dramatic efficacy of biological agents that act upon JAK2-driven signaling pathways, and given that inhibition of the JAK3 pathway is known to be immunosuppressive, Incyte has focused on the identification of inhibitors with greater selectivity for JAK2.
Additionally, Incyte believes there is strong genetic and early clinical evidence suggesting that blocking signaling through the JAK2 pathway may provide therapeutic benefits in a number of myeloproliferative diseases (MPDs), such as polycythemia vera, essential thrombocythemia and myeloid metaplasia.
Program Objectives for 2007
In today's presentation, Dr. Friedman will also review a number of 2007 objectives for the company's drug discovery and development programs including: -0-
1. In our HIV program, for our lead CCR5 antagonist, INCB9471,
present the final viral load reduction and safety data from the
Phase IIa trial, complete the required drug interaction studies,
and initiate a Phase IIb clinical study. For our follow-on CCR5
antagonist, INCB15050, complete Phase I and then determine
whether to further progress its development.
2. Present the final proof-of-principle data from the adipose fat
biopsy study and initiate and complete a one-month Phase IIa
clamp study in type 2 diabetics for INCB13739, our most advanced
11beta-HSD1 compound.
3. For our oral sheddase inhibitor INCB7839, complete the Phase
Ib/IIa dose-escalation trial in refractory cancer patients,
establish the maximum tolerated dose (MTD) and select a dose to
take forward in Phase II breast cancer trials and possibly one
other solid tumor type. In parallel, enroll additional cancer
patients into the Phase Ib/IIa trial, at the MTD, to assess
safety and potentially relevant biomarkers of sheddase inhibition
including HER2 extracellular domain levels, ECD.
4. For our lead CCR2 antagonist, INCB8696, initiate development as a
treatment for MS, beginning with a Phase I trial in healthy
volunteers.
5. For our JAK2 program, initiate several clinical trials, with the
potential to provide proof-of-concept results for at least one
indication before year-end.
6. Continue to advance additional follow-on compounds in our lead
programs as well as identify and progress new molecular entities,
targeted to clinically relevant targets, into IND-enabling
studies.
