Hallo Leute, bräuchte mal Eure Hilfe
Auf Grund meines schlechten Englisch verstehe ich hier nur Bahnhof.
Verstehe ich das richtig das Tarceva ein mißerfolg geworden ist.
EVtl. könnte jemand eine kurze zusammenstellung verassen.
Danke.
OSI Pharmaceuticals (OSIP) Summarizes Research Data Presented At The Annual Meeting Of The American Association For Cancer Research
MELVILLE, N.Y.--(BUSINESS WIRE)--March 31, 2004--OSI Pharmaceuticals, Inc. (Nasdaq: OSIP - News) today provided an informational update summarizing highlights from presentations made at this year`s Annual Meeting of the American Association for Cancer Research (AACR) held from March 27-31 in Orlando, Florida. Presentations included studies on the Company`s anti-cancer drug candidates: Tarceva(TM) (erlotinib HCl), a small molecule inhibitor of the epidermal growth factor receptor (HER1/EGFR), OSI-7904L, a novel liposomal thymidylate synthase (TS) inhibitor, and several drug candidates at earlier stages in the Company`s proprietary research discovery program.
Tarceva(TM): Pre-clinical Data Highlights
Tarceva(TM), currently in Phase III registration trials in refractory non-small cell lung cancer (NSCLC) and pancreatic cancer, is being developed by OSI in collaboration with Genentech, Inc. and Roche in a comprehensive, global development program.
Data presented in a series of pre-clinical studies revealed that higher EGFR expression levels appear to correlate with increased resistance to radiation in various tumor types, including bladder cancer. Study results showed that Tarceva(TM), when utilized in combination with radiation, contributes to an increase in radiosensitization (sensitivity of tissue to the effects of radiation therapy). Study results also showed that in five of six bladder cancer cell lines, Tarceva(TM) enhanced radio-responsiveness. Additionally, it was concluded that EGFR levels and autophosphorylation might be useful biomarkers to predict the outcome of radiation therapy. The results of these early studies are intriguing and provide a justification for follow up clinical studies.
Tarceva(TM) was also evaluated in a pre-clinical study for responsiveness in pancreatic tumor cell lines as a single agent. Data presented showed that these pancreatic tumor cell lines responded to Tarceva(TM) by demonstrating growth inhibition. These results from the pre-clinical single agent study, in common with previously reported clinical results in other diseases such as NSCLC, suggest that Tarceva(TM) as a single agent in pancreatic cancer may warrant future clinical investigation.
Additionally, pre-clinical studies presented at the meeting support the observation that Tarceva(TM) may demonstrate broad-based anti-tumor activity in a wide variety of solid tumor types including NSCLC, squamous vulvar, bladder, renal, colon, pancreatic and prostate cancers. This observation supports the notion that Tarceva(TM) might provide benefit as a single agent in a broad spectrum of disease settings.
OSI-7904L: Pre-clinical Data
OSI-7904L is a liposomal formulation of a potent TS inhibitor which is designed to improve activity by changing the pharmacokinetic (drug exposure) profile when compared to its non-liposomal formulation. OSI-7904L is being developed as a potential next-generation cytotoxic drug and competitor to 5-fluorouracil (5-FU) and capecitabine, two of the leading TS inhibitors currently marketed. Evidence suggests that prolonged infusions of 5-FU are associated with improved activity compared with the normal 5-FU protocol. OSI-7904L is designed to mimic the effects of a long-term infusion with a single dose of the liposomal product.
Data presented at this meeting showed that the combination of OSI-7904L with two platinum analogs commonly used in the treatment of gastrointestinal malignancies, cisplatin and oxaliplatin, was associated with increased efficacy as compared to the single-agent treatment. Experiments were conducted in five tumor models (two colon, three gastric) and the combination regimen was superior to the single agent in four of the five models. In addition, sequence dependency was observed in some models, and activity was greater when OSI-7904L was given after the platinum. These data demonstrate that OSI-7904L can be effectively and safely combined with platinum-based chemotherapy to improve the anti-tumor efficacy in colorectal and gastric xenograft models. In conclusion, these data support the Company`s ongoing clinical program for OSI-7904L. The clinical program includes two ongoing Phase I studies evaluating the use of OSI-7904L in combination with cisplatin or oxaliplatin. The clinical program also includes an ongoing Phase II monotherapy study in patients with previously untreated advanced gastric or gastro-esophageal junction cancer.
Highlights from OSI`s Research Program
The Company`s extensive pre-clinical research program focuses on the discovery of small molecule drugs directed toward core biological processes, by targeting signal transduction pathways that either drive cancer cell proliferation, prevent apoptosis (programmed cell death) and, in selected cases, inhibit angiogenesis. The Company`s most advanced research program is focused on the identification of a dual c-kit/KDR inhibitor. C-kit and KDR are both receptor tyrosine kinases, which function as key regulators in the control of tumor growth and angiogenesis (the process of blood vessel growth) respectively. Pre-clinical data presented at the meeting indicate that the lead compounds, in addition to inhibiting KDR, are also equally active against both mutant and wild type c-kit in cellular systems. Prolonged suppression of c-kit phosphorylation in vivo has been shown to correlate with anti-tumor activity in both mutant and wild type c-kit xenograft models. The lead compounds also have activity in tumor models that are thought to be dependent upon angiogenesis, highlighting the importance of the dual c-kit/KDR activity.
The Company`s most advanced candidate, OSI-930, is in late-stage pre-clinical development with IND (Investigational New Drug)-track status. The Company anticipates initiating clinical studies by year-end of calendar 2004.
Highlights from OSI`s Licensed Programs
CP-724,714, an oral HER2 receptor inhibitor, was discovered as part of OSI`s long-standing cancer discovery program with Pfizer Inc. and is currently in Phase I clinical development by Pfizer. Data presented at the meeting demonstrated that CP-724,714, has significant anti-proliferative activity in human breast cancer cell lines with elevated levels of HER2 (9 of 9 cell lines), whereas cell lines without HER2 amplification demonstrated activity in fewer cell lines (3 of 13 cell lines). Additional data reported suggested that the combination of CP-724,714 and Herceptin® provided better anti-tumor efficacy than treatment by either agent alone in a human breast carcinoma xenograft model.

@plaste
Mit dem heutigen Tage dürfte deine Frage beantwortet sein. Bin jetzt gerade über deinen OSIP-Thread gestolpert, weil ich dachte, im W.O. gäbe es ne rege Diskussion bzgl. der heutigen Meldung. Aber da war nix...
Ich lass die Ami`s erstmal zur Ruhe kommen, vor allem die Shorties, die sich jetzt bei 70 - 90 US$ eindecken mussten. Anschließend muss man dann nachrechnen, ob die Bewertung bei OSIP noch durchgeht. Auf dem ersten Blick nicht, denn aktuelle 3,5 Mrd.$ MarketCap sind schon etwas fett. Um dies zu rechtfertigen, müssen schon erstmal 350 Mio. in den Revenues drinstehen. Bis zur Vermarktung in 2005 und den ersten aussagekräftigen Verkaufszahlen passiert noch viel.
... ich glaube ich verkauf lieber mal paar Stück
bis später, vielleicht gibts ja noch paar OSI-Shareholder

Hallo,
ja es gibt noch ein paar!!
136 % Anstieg ??? .Ich hol mal ne Pulle aus dem Keller.

Na Hallo auch,
sind ja doch noch ein paar OSIs hier bei WO.
Na das ist wirklich eine tolle Meldung.
@ eddyumbra
kurzfristig gesehen hast Du wohl recht. Da ich aber long bin (bei 18 rein), halte ich mal die Bälle flach.
Grund: 2x Phase III, 6x Phase II)
Ich denke da ist noch einiges mehr drin. Auf die nächsten 1 - 2 Jahre.
Übrigens, hat noch einer von Euch die Optionsseine im Depot, die es bei der Cell Pathways Übernahme gab?
Was bedeuten die eigentlich bzw. wann werden die überhaupt handelbar?
mfg Plaste
Was haltet Ihr von Corixa?
Nachdem nun meine Nektar und OSIs weit über 100% gemacht haben, ist das mein nächster Favorit.
