Nivolumab With DC Vaccines for Recurrent Brain Tumors (AVERT)

AVeRT: Anti-PD-1 Monoclonal Antibody (Nivolumab) in Combination With DC Vaccines for the Treatment of Recurrent Grade III and Grade IV Brain Tumors

Patients will be randomized to one of two treatment arms - Group I and Group II. Group I will receive nivolumab monotherapy until surgical resection, and Group II will receive nivolumab alone and with DC vaccine therapy until surgical resection. During surgical resection blood and tumor samples will be assessed and compared. Following surgery, both groups will continue to receive DC vaccines (total of 8) and nivolumab therapy until confirmed progression.

• Conditions: Glioblastoma; Astrocytoma; Malignant Glioma
• Intervention / Treatment: Drug: nivolumab; Biological: DC

Detailed Description

This two-arm randomized trial will evaluate the safety of nivolumab in combination with DC vaccinations for the treatment of bevacizumab-naïve subjects with first or second recurrent, resectable World Health Organization (WHO) Grade III and IV malignant gliomas (MGs). Up to 66 patients will be enrolled and treated with the goal of accruing 30 patients (15 per arm) that will receive nivolumab and at least 3 vaccines. After enrollment, leukapheresis will be done for generation of DC vaccines and immunologic monitoring. All subjects will undergo standard of care tetanus booster vaccination with 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly (I.M.) into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Subjects will initially return every 2 weeks and receive approximately 3 infusions of nivolumab 3 mg/kg IV while the DC vaccines are being prepared from the initial leukapheresis and will then be randomized 1:1 to one of 2 arms (Group I: nivolumab only pre-surgery; Group II: nivolumab with DC vaccines pre-surgery). Patients who are unable to tolerate nivolumab will be withdrawn from the study and replaced. Patients whose DCs or Peripheral Blood Lymphocytes (PBLs) fail to meet release criteria will continue to receive nivolumab only and will not undergo repeat leukapheresis. For patients whose leukapheresis yields less than 4 vaccines, a repeat leukapheresis may be obtained a minimum of 2 weeks from the previous leukapheresis (and may be repeated as needed) if stable. Peripheral blood will be drawn for immune monitoring prior to treatment with the 4th cycle of nivolumab (first post-randomization infusion of nivolumab).

Group I Treatment Plan (Nivolumab Only Pre-Surgery) After randomization, patients in Group I will receive nivolumab 3 mg/kg IV every 2 weeks x approximately 8 weeks. The subject will then undergo surgical resection of tumor within approximately 1-3 weeks. Approximately 2-4 weeks later, leukapheresis is repeated for generation of DC vaccines and immunologic monitoring. Approximately 1 day to 2 weeks after leukapheresis, the subject will resume nivolumab 3mg/kg IV every two weeks with DC vaccine administration intradermally (i.d.) for a total of 3 vaccines. At the time of the third DC vaccine, patients will receive vaccine site pre-conditioning. A single dose of Td toxoid (1 flocculation unit (Lf) in 0.4 milliliters (mL) of saline) will be administered to a single side of the groin i.d. (as described above for all vaccine administrations 12-24 hours prior to the third DC vaccine, which is always given bilaterally at the groin site. At the vaccine #3 visit, prior to vaccine # 3 administration, erythema and induration measurements will be taken of pre-conditioning site. Group I subjects will then receive monthly DC vaccine administrations intradermally for 5 months or until progression (whichever comes first).Total vaccines to be administered will be 8 post-surgery unless subject is removed. Nivolumab will continue until progression. At the clinic visit following the last vaccine (#8), subjects will have peripheral blood drawn for immune monitoring prior to infusion of nivolumab.

Group II Treatment Plan (Nivolumab with DC Vaccines Pre-Surgery) After randomization, patients in Group II will receive the fourth cycle of nivolumab then receive nivolumab 3 mg/kg IV along with DC vaccines intradermally every 2 weeks x approximately 6 weeks for a total of 3 vaccines. At the time of the third DC vaccine, patients will receive vaccine site pre-conditioning. A single dose of Td toxoid (1 Lf in 0.4 mL of saline) will be administered to a single side of the groin i.d. 12-24 hours before the third DC vaccine, which is always given bilaterally at the groin site. At the vaccine #3 visit, prior to vaccine #3 administration, erythema and induration measurements will be taken of pre-conditioning site.The subject will then undergo surgical resection of tumor within approximately 1-3 weeks. Approximately 2-4 weeks later, leukapheresis is repeated for generation of DC vaccines and immunologic monitoring. Approximately 1 day to 2 weeks after leukapheresis, the subject will resume nivolumab 3mg/kg IV every two weeks. When DC vaccines have completed processing and are available for administration, monthly DC vaccine administrations as described above will be administered for 5 months or until progression (whichever comes first). Total vaccines to be administered will be 8 (3 pre- and 5 post-surgery) unless subject is removed. Nivolumab will continue until progression. At the clinic visit following the last vaccine (#8), subjects will have peripheral blood drawn for immune monitoring prior to infusion of nivolumab.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group I; Patients will receive nivolumab 3 mg/kg IV every 2 weeks for 8 weeks followed by surgery. Following resection, nivolumab and DC vaccine will be administered every 2 weeks (± 1) for a total of 3 vaccines, followed by biweekly treatment with nivolumab and monthly DC vaccinations for a total of 5 more vaccines. Patients will continue to receive nivolumab every 2 weeks until progression.	Drug: nivolumab; Nivolumab is a fully human monoclonal antibody that targets the programmed death-1 (PD-1) cluster of differentiation 279 cell surface membrane receptor. PD-1 is a negative regulatory molecule expressed by activated T and B lymphocytes. Binding of PD-1 to its ligands, programmed death-ligands 1 and 2, results in the down-regulation of lymphocyte activation. Inhibition of the interaction between PD-1 and its ligands promotes immune responses and antigen-specific T cell responses to both foreign antigens as well as self-antigens. Nivolumab is expressed in Chinese hamster ovary cells and is produced using standard mammalian cell cultivation and chromatographic purification technologies. The clinical study product is a sterile solution for parenteral administration.; Other Names: BMS-936558; MDX1106; Biological: DC; DCs are potent immunostimulatory cells that continuously sample the antigenic environment of the host and specifically activate cluster of differentiation 4 positive (CD4+) and cluster of differentiation 8 positive (CD8+) T-cells and B-cells. They are at the crossroads of many of the elegant networks of the immune system, and DCs represent the most promising contemporary biologic entity for realizing the promise of immunotherapy. Potent immune responses and encouraging clinical results have been seen in Phase I and II human clinical trials in systemic cancers. Numerous animal studies and the investigator's institution's humans studies have demonstrated potent antitumor responses using DC-based immunotherapy against MGs.; Other Names: DC vaccine; pp65 DC vaccine; Human CMV pp65-LAMP mRNA-pulsed autologous DCs; CMV pp65 DCs
Experimental: Group II; Patients will initially receive the fourth cycle of nivolumab then receive nivolumab 3 mg/kg IV and DC vaccine every 2 weeks for a total of 3 vaccines, and then surgery. Subsequent to surgery, the patient will resume biweekly treatment with nivolumab and monthly DC vaccinations for a total of 5 more vaccines. Patients will continue to receive nivolumab every 2 weeks until progression.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The Safety of Administering DC Vaccines With Nivolumab	The percentage of patients who experience unacceptable toxicity during combination treatment by arm is tabulated. Unacceptable toxicity is defined as any grade 3, 4, or 5 adverse event that is possibly, probably, or definitely related to either nivolumab or DC vaccination treatment during concurrent treatment, or any Grade 2 drug-related uveitis or eye pain or blurred vision that does not respond to topical therapy and does not improve to Grade 1 severity within the re-treatment period OR requires systemic treatment. In addition, any complication following resection (ex. excessive intracranial bleeding, delays in wound healing) that are prolonged longer than 4-6 weeks post-surgery will be considered an unacceptable toxicity.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival	Survival is defined as the time between first initiation of nivolumab and death, or last follow-up if the patient remains alive. The Kaplan-Meier estimator will be used to describe the overall survival (OS) experience of all patients. Median OS is presented. Patients who are not able to tolerate nivolumab and are removed from the study will not be included in these analyses. Patients for whom DC vaccines cannot be manufactured will not be included in the survival analyses.	approximately 4 years from study initiation
Progression Free Survival (PFS)	PFS is defined as the time between treatment initiation and initial progression or death, or date of last follow-up if the patient remains alive without disease progression. The Kaplan-Meier estimator will be used to describe the PFS experience of all patients. Median PFS is presented. Patients who are not able to tolerate nivolumab and are removed from the study will not be included in these analyses. Patients for whom DC vaccines cannot be manufactured will not be included in the survival analyses. Tumor assessment will be made using Response Assessment in Neuro-Oncology (RANO) criteria, which defines progressive disease as an increase by at least 25% in the sum of the products of perpendicular diameters from the baseline scan, a significant increase in T2/FLAIR non-enhancing lesions, or clinical decline	6 to 48 months from study initiation
