סנופי אבנטיס הודיעה היום כי FDA אישר סקירה מוקדמת של התרופה Taxotere

(Docetaxel), בשילוב עם הטיפול הסטנדרטי (Cisplatin + 5-Fluorouracil) לסרטן קיבה מתקדם.

הטיפול הנוסף מבוסס על נתונים ממחקר בינלאומי גדול בשלב 3, TAX 325, שכלל 457 חולי סרטן קיבה במצב מתקדם. משתתפים שטופלו במשטר כימותרפיה על בסיס Taxotere (Docetaxel, Cisplatin ו-5-Fluorouracil) הראו סיכויי הישרדות טובים יותר סך הכל, בהשוואה לנבדקים שקיבלו טיפלו סטנדרטי של Cisplatin ו-5-Fluorouracil (9.2 חודשים לעומת 8.6 חודשים, חציון הישרדות) עם ירידה של 23% בסיכון היחסי לתמותה (P=0.02). סיכויי הישרדות לשנתיים עמדו על 18%, לעומת 9%, לטובת מטופלי Taxotere. באירופה תוספת הטיפול הזו כבר נבדקת ע”י EMEA, על בסיס תוצאות מחקר TAX 325.

FDA העניק Priority Review לטיפולים אלו, להם פוטנציאל לשפר משמעותית את הטיפול.

רופאים המטפלים בדחיפות בחולים עם סרטן קיבה, זקוקים לשיטות חדשות ויעילות יותר, ואופציות טיפול טובות יותר בכדי לסייע לחולים אלו. אם Taxotere יאושר לשימוש, שילובו במשטר הכימותרפיה הסטנדרטי עשוי להיות ההתפתחות החשובה ביותר, בעשור האחרון, בטיפול בסרטן קיבה מתקדם.

להלן ההודעה המלאה כפי שפורסמה ע”י סנופי אבנטיס:

About Taxotere®

Taxotere® is currently approved in three types of cancers :

Breast Cancer:

• In the United States and in Europe Taxotere®, as the approval to treat patients with locally advanced or metastatic breast cancer after failure of prior chemotherapy.


• It is also approved in Europe in combination with doxorubicine for patients who have received prior cytotoxic therapy for this condition and in combination with capecitabine after failure of cytotoxic therapy which would have included anthracycline.


• In adjuvant setting (post surgery) it is approved in the US and in Europe in combination with doxorubicin and cyclophosphamide (TAC regimen) for the treatment of patients with operable, node-positive breast cancer.


• Finally, in Europe, Taxotere® is approved in combination with trastuzumab for the treatment of patients with metastatic breast cancer overexpressing Her2 receptor.

Lung Cancer:

• In the US and in Europe Taxotere®, in combination with cisplatin, is  approved for the treatment of patients with unresectable locally advanced or metastatic non-small cell lung cancer (NSCLC) who had not received prior chemotherapy, and it also is approved, as a single agent, for patients with unresectable locally advanced or metastatic NSCLC after failure of prior platinum-based chemotherapy.

Prostate Cancer:

• Taxotere® is approved for use in combination with prednisone as a treatment for androgen-independent (hormone-refractory) metastatic prostate cancer in the US and in Europe.
                                                              

About the TAX 325 Study

Locally advanced or metastatic gastric cancer (MGC) has a poor prognosis with 2-year survival of only 11.5 percent (source??). This study was undertaken to evaluate the benefits of adding Taxotere® to a standard chemotherapy regimen. The primary study endpoint was time to tumor progression (TTP), which was significantly improved with Taxotere® based therapy (5.6 months) compared to standard treatment (3.7 months) with a 32% reduction in the risk of progression (log rank p=0.0004). The main secondary endpoint was to detect a statistically significant increase in overall survival. Response rate, time to treatment failure, duration of response, safety profiles, Quality of life and disease related symptoms were collected and evaluated as secondary objectives as well.

The Taxotere® (docetaxel) combination resulted in an increased incidence of diarrhea (19% vs 8%) and low white blood cell counts (82% vs. 57%) which was complicated by fever or infection in 29 vs 12% of cases. Prophylactic use of GCSF was not recommended in this study. In total, 81.4% of the patients experienced at least one grade3/4 side effect with the Taxotere based regimen versus 75.4% in the control arm. And, there was a 57 percent reduction in Grade 3-4 neutropenia in patients who received G-CSF.

“In this sick patient population, the tolerability of cytotoxic regimens is limited. However, Taxotere® combined with cisplatin plus 5FU (TCF) along with appropriate risk management shows promise in the treatment of advanced stomach cancer,” said Professor Eric Van Cutsen from the University Hospital of Gasthuisberg, Leuven, Belgium, European principal investigator of the TAX325 trial.

These results were presented at the American Society of Clinical Oncology (ASCO) annual meeting in 2005.
