Brief Summary:

The purpose of the study is to assess the safety, tolerability and the HPV-specific immune responses of different doses of ISA101 vaccine with or without pegylated IFNα as combination therapy with carboplatin and paclitaxel.

To qualitatively assess the safety profile and the HPV-specific immune responses of ISA101b vaccine compared to ISA101 at the same dose levels.

To assess the safety and the HPV-specific immune responses of ISA101b vaccine with carboplatin, paclitaxel with or without bevacizumab.

Condition or disease Intervention/treatment Phase
Cervical Cancer Drug: ISA101/ISA101b Phase 1 Phase 2

Detailed Description:
A majority of cervical carcinomas are caused by an uncontrolled, persistent infection with high risk Human Papilloma Virus (HPV). ISA101/ISA101b is a novel therapeutic synthetic long peptide (SLP) vaccine targeting HPV16 which is being developed and has shown efficacy in patients with high-grade premalignant vulvar lesions caused by HPV with only minor toxicity. For most advanced cancers, chemotherapy remains the treatment modality of choice but has been considered to be immunosuppressive. However, accumulating evidence indicates that many modalities of conventional chemotherapy not only are less immunosuppressive than previously thought but in fact can exert favorable effects on the tumor micro-environment by interfering with suppressive immune cells and by stimulating the release of immune activating molecules by tumor cells. Thus chemotherapy may enhance tumor-specific immunity and synergize with cancer immunotherapy. Addition of pegylated interferon alpha (IFNα) two-b (IIb) to vaccination might even further improve the immune response. This multicenter, open label, non-randomized Phase I/II study will be performed to assess the safety and tolerability of the ISA101/ISA101b vaccine, and the immune modulating effects of ISA101 (with or without pegylated IFNα)/ISA101b when combined with carboplatin and paclitaxel, with or without bevacizumab.

Arm Intervention/treatment
Experimental: ISA101/ISA101b
The maximum total treatment duration for a patient is six cycles (1 cycle is 21 days) for a total of 18 weeks. On day 15 of cycles 2, 3 and 4 patients are to receive the vaccination scheme of ISA101/ISA101b. Patients will be vaccinated with a fixed dose of ISA101/ISA101b every three weeks for a total of three rounds of vaccination. Four dose levels of ISA101 have been tested. ISA101b will be tested in bridging cohorts.
Drug: ISA101/ISA101b
Four dose levels ISA101/ISA101b
Other Name: HPV Type 16 E6/E7 Synthetic Long Peptides Vaccine

Primary Outcome Measures :
  1. HPV-specific immune responses [ Time Frame: 4 months ]
    HPV-specific immune responses to different doses of the ISA101 vaccine with or without pegylated interferon alpha (INFα) as combination therapy with carboplatin and paclitaxel will be determined. The HPV-specific immune responses to ISA101b will be qualitatively compared to the responses at the same dose level(s) of ISA101.

Secondary Outcome Measures :
  1. Evaluate the clinical efficacy by antitumor efficacy according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 [ Time Frame: one year ]

Other Outcome Measures:
  1. Evaluate the general responsiveness of the immune system as measured by explorative assays. [ Time Frame: 4 months ]

    General responsiveness of the immune system as measured by explorative assays in particular:

    1. Lymphocyte proliferation
    2. Antigen Presenting Cell (APC) function tests
    3. Assay of myeloid and lymphoid cell composition
    4. Recall proliferative responses of Peripheral Blood Mononuclear Cells(PBMCs) in response to common microbial antigens
