Progenics began developing RELISTOR in 2001 and continued development and commercialization worldwide except Japan withWyeth Pharmaceuticals (now a Pfizer Inc.subsidiary) pursuant to a 2005 collaboration agreement that was terminated in October 2009.
Progenics公司开始于2001年开发RELISTOR产品,根据2005年的一项合作协议,除日本惠氏制药公司(现在是辉瑞公司的子公司)以外的全球开发和商业化,2009年10月后被终止。
Under our 2008 License Agreement, Ono began clinical testing of RELISTOR subcutaneous injection in June 2009. See Licenses – RELISTOR . Inaddition to our pending sNDA for subcutaneous RELISTOR in non-cancer pain patients, we have also received U.S., E.U. and Canadianapprovals to market RELISTOR in pre-filled syringes, which are designed to ease preparation and administration for patients and caregivers,and expect Salix to begin distributing RELISTOR in this presentation later this year.
Oral RELISTOR. As noted above, we and Salix recently announced top-line data from a phase 3 trial of oral RELISTOR in patients
with non-cancer pain.http://www.ukthesis.org/Thesis_Tips/
Oncology
Through PSMA Development Company LLC, our wholly owned subsidiary, we conduct research and development programs directedat prostate specific membrane antigen , or PSMA , a protein that is abundantly expressed on the surface of prostate cancer cells as well ascells in the newly formed blood vessels of many other solid tumors. The principal focus of these efforts is our fully human monoclonal ADC ,which utilizes technology licensed to us from Sloan-Kettering Institute for Cancer Research and Seattle Genetics, and is designed to deliver achemotherapeutic agent to cancer cells by targeting the three-dimensional structure of the PSMA protein on these cells and binding to andinternalizing within the cell. We believe a PSMA-directed therapy may have application in prostate cancer and solid tumors of other types ofcancer. We are conducting a phase 1 clinical trial of PSMA ADC for the treatment of prostate cancer which we expect will be completed in2012, and if the results are successful we plan then to commence a Phase 2 trial of PSMA ADC in advanced prostate cancer.
We also recently presented data from preclinical studies of novel multiplex phosphoinositide 3-kinase (PI3K) inhibitors -- synthetic,
我们最近还提出了新颖的复用磷酸肌醇3 - 激酶(PI3K)抑制剂的临床前研究的数据 - 合成。
small-molecule compounds identified by us that in laboratory studies have blocked both PI3K, a key regulator of one molecular signaling,pathway, and MNK, an oncogenic kinase in the Ras pathway. We believe simultaneously blocking these interlinked cellular pathways mayprovide a strategy to combat some of the most aggressive forms of cancer.
We are seeking to in-license or acquire opportunities in the oncology field and related supportive, diagnostic and/or other areas thatare complementary to these ongoing initiatives and our oncology focus generally.
Licenses
Following is a summary of significant license agreements under which we have in- and/or out-licensed rights to use certain

Salix is paying us royalties ranging from 15 to 19 percent on its net sales of RELISTOR as well as 60% of anyupfront, milestone, reimbursement or other revenue (net of costs of goods sold, as defined, and territory-specific research and development
expense reimbursement) it receives from sublicensees in respect of any country outside the U.S. We have licensed to Ono Pharmaceutical the rights to subcutaneous RELISTOR in Japan, where Ono is responsible for developingand commercializing subcutaneous RELISTOR, including conducting clinical development to support regulatory marketing approval and will own the subcutaneous filings and approvals relating to RELISTOR. We received a $15.0 million upfront payment from Ono, and are entitled to receive up to an additional $20.0 million upon achievement of development milestones. Ono is also obligated to pay us royalties and commercialization milestones on sales of subcutaneous RELISTOR in Japan. Ono has the option to acquire the rights to develop andcommercialize other formulations of RELISTOR in Japan, on terms to be negotiated separately. Supervision of and consultation with respect Ono’s development and commercialization responsibilities are carried out by joint committees. The Ono License contains, among other terms,provisions which permit termination by either party upon the occurrence of certain events.
