Gruß ... Andreas Thema: GPC Biotech 2003 meldet GPC folgendes Martinsried/Munich (Germany) and U.S. Research Facilities in Waltham/Boston, Mass. and Princeton, N.J., September 2, 2003 - GPC Biotech AG (Frankfurt Stock Exchange: GPC; TecDax 30) today announced that it has received written confirmation from the FDA (U.S. Food and Drug Administration) that the Company may initiate a Phase 3 registrational trial with satraplatin plus prednisone in patients with hormone-refractory prostate cancer who have failed prior treatment with chemotherapy. * Company has successfully completed Special Protocol Assessment (SPA) and “End of Phase 2″ meeting with U.S. Agency * Primary endpoint for accelerated approval will be time to disease progression This notification is the culmination of the Company’s satisfactory completion of both a Special Protocol Assessment (SPA) and an “End of Phase 2″ meeting with the FDA. GPC Biotech requested a review of the Phase 3 clinical trial protocol under an SPA, part of procedures published by the FDA in 2002 to encourage a meaningful dialogue between the Agency and a drug developer prior to the initiation of registrational studies. Under this SPA program, the FDA evaluates whether the protocol for a clinical trial is adequate to meet scientific and regulatory requirements for marketing approval of the drug by the FDA. The satraplatin Phase 3 clinical trial protocol has now successfully completed this SPA process. In addition, GPC Biotech held an “End of Phase 2″ meeting with the FDA. The purposes of this type of meeting include: assessing the safety of the drug regimen to be tested in the Phase 3 trial, evaluating the Phase 3 plan, and identifying any additional information that will be needed to support a marketing application. The combination of this meeting and the SPA provided GPC Biotech the opportunity to hold comprehensive and meaningful discussions with the FDA about the many components that will eventually be part of its U.S. NDA (New Drug Application) filing. The satraplatin registrational Phase 3 study will assess the safety and efficacy of satraplatin in combination with prednisone as a second-line chemotherapy regimen in patients with hormone-refractory prostate cancer (HRPC). This will be a multicenter, global, randomized study. It is modeled on the smaller Phase 3 trial successfully conducted by the EORTC (European Organization for Research and Treatment of Cancer), the results of which were presented at the ASCO (American Society of Clinical Oncology) Annual Meeting in June 2003 (see GPC Biotech press release dated June 3, 2003). The GPC Biotech Phase 3 registrational trial will compare satraplatin plus prednisone versus prednisone alone. Prednisone is a synthetic hormone often used to treat advanced prostate cancer. The primary endpoint of the registrational trial for accelerated approval will be the time to disease progression. The study’s objectives also will include the evaluation of pain control and survival, as well as an assessment of drug safety in this patient population. ———————————————————- aus dieser vermeintlichen intensiven Absprache ergeben sich jetzt plötzlich die gestrigen Diskrepanzen bzgl. der Methodiken —————————————————————– heute schreibt GPC: Martinsried/Munich (Germany) and Princeton, N.J., July 25, 2007 – GPC Biotech AG (Frankfurt Stock Exchange: GPC; TecDAX index; NASDAQ: GPCB) today announced that the Oncologic Drugs Advisory Committee (ODAC) for the U.S. Food and Drug Administration (FDA) recommended (12-0) that the FDA should wait for the final survival analysis of the SPARC trial before deciding whether the satraplatin application is approvable for the treatment of hormone-refractory prostate cancer patients whose prior chemotherapy has failed. The FDA is not bound by the recommendations of advisory committees but will consider their advice when reviewing an applicant’s NDA. The Company said that, due to a recent slowing in the reported rate of deaths in the SPARC trial, final overall survival results could take longer than the previously communicated timeframe of the fall of this year. “While we are extremely disappointed that ODAC has recommended that the FDA wait for the results of the overall survival analysis, we will continue to work with the FDA as the agency continues its review of the satraplatin application,” said Bernd R. Seizinger, M.D., Ph.D., Chief Executive Officer of GPC Biotech. “We continue to believe strongly in the potential for satraplatin to help hormone-refractory prostate cancer patients who today have very limited treatment options.” ———————————————————————————– ohne weiteren kommentar ! ———————————————————————————– Wichtig ist für mich dabei allgemein, nicht nur im Fall Satraplatin, dass man sich seitens der FDA auf nichts mehr verlassen kann. Wozu wird ein SPA vereinbart und genehmigt ?? Fazit: Ab sofort heisst u.a. dieser Vorfall für mich, noch vorsichtiger zu sein bei der Beurteilung bevorstehender FDA-Entscheidungen. Und wirklich alles muss man selbst recherchieren und zwar so, dass man es selbst beurteilen kann. Bzgl. Satraplatin und dem GPC-Aktienkurs ist der unbestimmte und eher spätere Termin für die Bekanntgabe und Einreichung der OS-Daten natürlich ein Desaster. Nachdem auch weitere, wichtige Prüfungsergebnisse z.B. bei NSCLC frühestens Ende des Jahres kommen, steht dem GPC-Kurs ein hartes Restjahr bevor. Denn auch die Bekanngabe der Phase I Daten des Antikörpers wird denn Kurs kaum nachhaltig bewegen, denn hier sind wir noch Jahre vom Markt weg und selbst bis zu brauchbaren Phase II Ergebnissen dauert es noch lange. D.h. aktuell kann ich nicht erkennen, wo auf absehbare Zeit der fund. Nährboden für eine nachhaltige Erholung sein soll. |
