Da ist es wieder!
In unserer Phase3 steht nicht wann die Krankheit wieder aufgetreten ist.
Denke das werden wir in den Ergebnissen sehen. Die werden die ( vor 6, 6-12 und nach 12 ) alle eingebunden haben, um Dox und Zopt genauer vergleichen zu können.
Second-Line Therapy for Endometrial Cancer: The Need for Better Options
Regardless of subtype, once endometrial cancer metastasizes or recurs, median survival is short, on the order of 12 to 15 months for patients with measurable disease
In Zopt Phase3 dürfen auch kleinere Tumore. Besser behandelbar mit größeren Ansprechen!
Carboplatin/paclitaxel is standard adjuvant therapy for stage III endometrial cancer and is also standard first-line therapy for metastatic or recurrent disease based on noninferiority and better tolerability compared with the three-drug regimen of paclitaxel/doxorubicin/cisplatin.9 Most of the landmark trials for metastatic disease were conducted before the widespread use of adjuvant chemotherapy, raising questions about the best treatment for women who have had prior adjuvant treatment. A recent publication suggests that the concept of “platinum sensitivity” be applied to endometrial cancer much as it is currently used for ovarian cancer. RRs to second-line platinum-based therapy for patients with platinum-free intervals of less than 6 months, 6 to 12 months, 12 to 23 months, and more than 24 months were 25%, 38%, 61%, and 65%, respectively. Median PFS for patients with platinum-free intervals of less than 12 months and ≥ 12 months was 4.4 months and 10.3 months, respectively.32 It seems likely that, as has been demonstrated with ovarian cancer, this paradigm of chemotherapy sensitivity applies to the use of most cytotoxic chemotherapy agents in general (ie, the longer the time since first-line chemotherapy, the better the RR and the longer the PFS). The second-line trials listed in Table 2 were performed in the setting of second-line chemotherapy for metastatic disease, and given that only approximately 20% to 25% of chemotherapy-naive patients have a complete response to first-line chemotherapy,7 the majority of patients in these studies would have had platinum-resistant or platinum-refractory tumors.
Doxorubicin is active in treating advanced endometrial cancer. It was the first chemotherapy widely used for metastatic endometrial cancer and produced first-line RRs of 19% to 37%.34,35 However, it appears to have little activity as a second-line agent, with one retrospective review reporting a discouraging complete lack of responses.36 A firmer estimate will come from results of an ongoing phase III trial that randomly assigned patients with endometrial cancer who had one prior chemotherapy regimen to either doxorubicin or the experimental agent, doxorubicin conjugated to a luteinizing hormone-releasing hormone agonist (zoptarelin doxorubicin; NCT01767155: Study Comparing AEZS-108/ZoptEC [Zoptarelin Doxorubicin in Endometrial Cancer] to Doxorubicin as a Second Line Therapy of Endometrial Cancer). Eighty percent of endometrial cancers express luteinizing hormone-releasing hormone receptors, and it is hypothesized that this targeted drug can increase responses and/or decrease the toxicity of doxorubicin.37 At this time, second-line cytotoxic therapy for platinum/taxane-resistant endometrial cancer is relatively ineffective, and clinical trial enrollment should be encouraged.
