简要总结
This is a Phase II study of Vigil™ autologous tumor cell vaccine integrated with bevacizumab. All patients will have had Vigil™ prepared and stored from initial primary surgical debulking. Patients meeting eligibility criteria will receive Vigil™ 1.0 x 10e7 cells/intradermal injection once every 4 weeks and bevacizumab 10 mg/kg intravenously every 2 weeks.

研究组 & 干预措施
Vigil™ Vaccine
Patients will receive 1.0 x 10e7 cells via intradermal injection one day each cycle for a maximum of 12 doses as long as sufficient material is available and subject is clinically stable. Additionally, patients will receive bevacizumab 10 mg/kg intravenously (prior to Vigil™ administration) every 2 weeks (4 weeks=1 cycle).
干预措施: Vigil™ Vaccine (Biological)

结局指标
主要结局
Time to Progression
时间窗: 24 months
Time to progression (TTP) following bevacizumab integrated with Vigil vaccine in patients failing standard of care in study CL-PTL 105 or in those not otherwise qualifying after vaccine production. This will be measured from the treatment start date (date of first dose) to either the date the patient is first recorded as having disease recurrence (even if the patient went off treatment because of toxicity), or the date of death if the patient dies due to any causes before progression.
Response Rate
时间窗: Up to 12 months
Response will be evaluated using the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline.
次要结局
- Number of Alive Subjects(24 months)
- Enzyme-Linked ImmunoSorbent Spot (ELISPOT)(Baseline, End of Treatment (30 days after last dose) up to 12 months)
