Clinical Trial Summary

The aim of this study is to assess the potential benefit of the addition of immunotherapy with VGX-3100 and INO-9012 (i.e. INO-3112) to concomitant CRT or, to concomitant CRT and continued as adjuvant in patients with locally advanced cervical cancer.

Safety run-in: To test the safety of CRT combined with immunotherapy with INO-3112. This safety run-in phase will include the first 3 patients treated in each of the two INO-3112 combination arms who are exposed to at least two immunotherapy doses and evaluate whether the combination does not pose undue immediate risks to the patients further enrolled in the trial.

Phase II:To demonstrate sufficient activity in the experimental combination arms to warrant a further phase III conclusive trial based on progression free survival (PFS) at 18 months assessed by RECIST by the local investigator. The efficacy will be assessed within each experimental arm while the standard arm will serve as a reference arm to check the reliability of the results.

Eligibility

Main inclusion criteria:

Registration step

• Age 18 years or older;

• Newly diagnosed locally advanced cervical cancer defined as FIGO 2009: stage IB2, IIA&IIB, IIIA&IIIB or IVA disease;

• No evidence of distant metastases (Stage IVB);

• Histological diagnosis of squamous cell carcinoma, adenocarcinoma or adenosquamous cell carcinoma of the cervix is accepted. Not accepted are small cell, clear cell and other rare variants of the classical adenocarcinoma;

• Availability of HPV 16 and HPV 18 testing;

• No HIV seropositive, Hepatitis B or C (unless sustained virologic response achieved by anti-HCV therapy);

• Written informed consent must be given according to ICH/GCP, and national/local regulations

Randomization step

• Positive for HPV 16 and/or HPV 18 as assessed by central lab;

• WHO/ECOG performance status 0 - 2

• Adequate hematological, liver and renal functions

• ECG with no clinically significant findings as assessed by the investigator performed within 30 days of signing the informed consent form

• Absence of current malignancies at other sites, with the exception of adequately treated basal or squamous cell carcinoma of the skin. Cancer survivors, who have undergone potentially curative therapy for a prior malignancy, who have no evidence of that disease for five years and are deemed at low risk for recurrence, are eligible for the study;

• No prior history of clinically significant autoimmune disease, Crohn's disease, ulcerative colitis;

• No history of previous therapeutic HPV vaccination (individuals who have been immunized with licensed prophylactic HPV vaccines (e.g. Silgard®, Cervarix®, Gardasil®) are not excluded);

• No known or suspected hypersensitivity to component(s) of investigational product or cisplatin contraindication (e.g. peripheral neuropathy = grade 2 or ototoxicity = grade 2 as per CTCAE v4);

• No previous pelvic RT;

• No previous chemotherapy for this tumor;

• No patients who have undergone a previous hysterectomy or will have a hysterectomy as part of their initial cervical cancer therapy;

• No receipt of any immunotherapy within 4 weeks of start of protocol treatment;

• No prior major surgery within 4 weeks of randomization from which the patient has not recovered.

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Related Conditions & MeSH terms

• Uterine Cervical Neoplasms

Intervention

Biological:
• INO-3112 vaccine
INO-3112 i.e. the combination of VGX-3100 and INO-9012, specifically: VGX-3100 (HPV16 and HPV18 E6-E7 DNA vaccine) will be administered at 3 mg per plasmid (6 mg total DNA) INO-9012 (IL-12 DNA plasmid) will be administered at 1 mg per dose will be administered using the CELLECTRA® electoporation device

Radiation:
• Radiotherapy (Extrernal beam radiotherapy + brachytherapy)
The whole pelvis will be irradiated with 45 - 50.4 Gy in 25-28 fractions in fractions of 1.8 Gy over 5 weeks daily. Those patients with pelvis positive and/or para-aortic positive lymph nodes should be treated with an elective dose to the para-aortic area of 45 Gy in fractions of 1.6-1.8 Gy in 25-28 fractions. Pelvic and para-aortic nodes known to contain gross/macroscopically visible disease and heavily involved parametria or tumor areas that may lie beyond the high-dose range of brachytherapy should be treated with additional small volume boost of EBRT to a total dose of 60-65 Gy using a combination of either sequential and/or concomitant boost. Fractions of 1.8-2 Gy can be used in the sequential boost.

Drug:
• Cisplatin chemotherapy
Cisplatin chemotherapy will be administered i.v. at a dose of 40 mg/m2 (total 5 cycles during week 1-5) weekly in concomitance with RT with the total dose not to exceed 70 mg per week.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Occurence of Adverse Events	In order to ensure adequate safety of the combination treatment, a safety run-in will be performed. This safety run-in phase will include the first 3 patients treated in each of the experimental arms (arms A & B) exposed to at least two immunotherapy doses. The acute safety of the combination of INO-3112 with concomitant CRT will be evaluated similar to a phase I "3+3" safety design. The safety evaluation will be done by the Data Safety Monitoring Board who will invoke an IDMC evaluation of the whole study if undue safety signals are observed.; Acute toxicity is defined as a grade 3 or more related AEs occurring between the first dose of vaccine administration and up to 14 days after the second dose of immunotherapy. Adverse events are graded according to the NCI CTCAE v4.0. Use of narcotics will be reviewed on case-to-case basis by a medical review team to assess its relevance towards the safety evaluation	6 months	Yes
Primary	Progression free survival (PFS) at 18 months assessed by RECIST	Progression Free Survival at 18 months assessed by local investigator	18 months	No
