OBJECTIVE: This two-stage phase II study was designed to assess the activity of the combination of temsirolimus and bevacizumab in patients with recurrent or persistent endometrial carcinoma (EMC).
METHODS: Eligible patients had persistent or recurrent EMC after receiving 1-2 prior cytotoxic regimens, measurable disease, and Gynecologic Oncology Group performance status ≤ 2. Treatment consisted of bevacizumab 10 mg/kg every other week and temsirolimus 25 mg IV weekly until disease progression or prohibitory toxicity. Primary end points were progression-free survival (PFS) at six months and overall response rate using RECIST criteria.
RESULTS: Fifty-three patients were enrolled. Forty-nine patients were eligible and evaluable. Median age was 63 years, and prior treatment consisted of one or two regimens in 40 (82%) and 9 (18%), respectively. Twenty (41%) received prior radiation. Adverse events were consistent with those expected with bevacizumab and temsirolimus treatment. Two gastrointestinal-vaginal fistulas, one grade 3 epistaxis, two intestinal perforations and 1 grade 4 thrombosis/embolism were seen. Three patient deaths were possibly treatment related. Twelve patients (24.5%) experienced clinical responses (one complete and 11 partial responses), and 23 patients (46.9%) survived progression free for at least six months. Median progression-free survival (PFS) and overall survival (OS) were 5.6 and 16.9 months, respectively.
CONCLUSION: Combination of temsirolimus and bevacizumab is deemed active based on both objective tumor response and PFS at six months in recurrent or persistent EMC. However, this treatment regimen was associated with significant toxicity in this pretreated group. Future study will be guided by strategies to decrease toxicity and increase response rates.
