About this study
Official title: Protocol ATI001-102 Substudy: Evaluation of Ad-RTS-hIL-12 + Veledimex in Combination With Nivolumab in Subjects With Recurrent or Progressive Glioblastoma
This research study involves an investigational product: Ad-RTS-hIL-12 given with veledimex for production of human interleukin-12 (IL-12). IL-12 is a protein that can improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.
Nivolumab is an antibody (a kind of human protein) that is being tested to see if it will allow the body's immune system to work against glioblastoma tumors. Opdivo (Nivolumab) is currently FDA approved in the United States for melanoma (a type of skin cancer), non-small cell lung cancer, renal cell cancer (a type of kidney cancer), Hodgkin's lymphoma but is not approved in glioblastoma. Nivolumab may help your immune system detect and attack cancer cells. Ad-RTS-hIL-12 and veledimex will be given in combination with Nivolumab to enhance the IL-12 mediated effect observed to date.
The main purpose of this substudy is to evaluate the safety and tolerability of a single tumoral injection of Ad-RTS-hIL-12 given with oral veledimex in combination with nivolumab.
Read the detailed description
Eligible patients will receive one dose of nivolumab, via infusion, one week prior to standard of care craniotomy and tumor resection (subtotal or total). On the day of surgery, patients will receive one dose of veledimex before the resection procedure. Ad-RTS-hIL-12 will be administered by free-hand injection. Patients will continue on oral veledimex for 14 days. Following veledimex, patients will receive nivolumab via infusion every two weeks.
The study is divided into three periods: the screening period, the treatment period and the follow-up period.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adverse Events (AEs)
Evaluation of adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE) v4.03 will be based on the incidence, intensity and type of adverse event.
AEs will be regarded as treatment-emergent adverse events (TEAEs) during the treatment period regardless of relationship to study drug if:
- The AE occurred or worsened from baseline during or after administration of the first dose of study drug (on or after Day 0).
Measured: 2 years and 4 months
Number of Participants With Veledimex Dose Compliance
Evaluation will be based on expected dose compliance. Subjects were instructed to document veledimex dosing compliance in a subject diary, including the time each dose was taken, the time of the last meal prior to administration of veledimex, the number of capsules taken, whether the subject missed any veledimex doses, and reason for any missed doses. Investigational product container(s) with any remaining capsules were returned to the study staff on Day 15, and staff assessed dose compliance.
Measured: From Day 0 through Day 14 for each participant
Secondary outcomes (15)
Number of Participants With a Dose-Limiting Toxicity (DLT)
The primary objective was to determine the Maximum Tolerated Dose (MTD), defined as the dose at which fewer than 33% of subjects experience a Dose-Limiting Toxicity (DLT). The MTD was not reached; a Maximum Administered Dose (MAD) of 20mg veledimex and 3mg/kg nivolumab was determined. This measure reports the number of subjects who experienced a DLT during the first treatment cycle in each dose cohort.
Measured: The first treatment cycle (21 days).
Tumor Objective Response Rate (ORR)
To determine investigator assessment of response including tumor ORR of Ad-RTS-hIL-12 + veledimex when administered in combination with nivolumab. Investigator assessment of ORR was determined according to Immunotherapy Response Assessment in Neuro-Oncology (iRANO) criteria. iRANO is a set of criteria built on RANO criteria but adapts them for immune-related effects to evaluate treatment response in brain tumor patients receiving immunotherapy. It addresses unique challenges like pseudoprogression, where immune-related inflammation mimics tumor growth on imaging allowing continued treatment despite early radiographic worsening if the patient is clinically stable. This criteria requires confirmation of progression with follow-up imaging ≥3 months later, especially within the first 6 months of immunotherapy.
Measured: 2 years and 4 months
Progression Free Survival (PFS)
PFS is the time in days from the first treatment (either veledimex or Ad-RTS-hIL-12) to the first assessment on which the overall response is reported as disease progression (per Response Assessment in Neuro-Oncology [RANO] or Immunotherapy Response Assessment in Neuro-Oncology [iRANO] criteria). Subjects withdrawing from the study will be censored at their last non progressive disease response assessment. If a subject does not have a non-progressive disease response assessment, the subject will be censored on the date of the first treatment as described above.
Measured: 2 years and 4 months
Rate of Pseudo-progression (PSP)
PSP -- Progression free survival was originally defined for determination of PSP requiring confirmation of progression (per Response Assessment in Neuro-Oncology [RANO] or Immunotherapy Response Assessment in Neuro-Oncology [iRANO] criteria).
Measured: 2 years and 4 months
Overall Survival (OS)
The percentage of participants alive at each time point (6, 9, 12, 15, 18, and 24 months) are reported.
Measured: Up to 24 months
Changes From Baseline in Cellular Responses Elicited by Ad-RTS-hIL-12 and Veledimex in Combination With Nivolumab.
Blood samples for pharmacodynamic biomarker evaluation were collected at screening, during treatment, and post-treatment. The immunological and biological response markers include serum cytokines (IL-12 and IFNℽ), and T and B cell subpopulations. Serum IL-12 and downstream IFNℽ expressions are reported by time point.
Measured: From Screening through Day 28, assessed at Screening and Days 0, 1, 3, 7, 14, and 28
Changes From Baseline in Humoral Immune Responses Elicited by Ad-RTS-hIL-12 and Veledimex in Combination With Nivolumab.
Blood samples for pharmacodynamic biomarker evaluation were collected at screening, during treatment, and post-treatment.
Whole blood flow cytometry was used to assess the circulating blood cell subpopulations (e.g., T-reg and T cell panels).
Measured: From Screening through Day 28, assessed at Screening, Days 0, 14, and 28
Veledimex Pharmacokinetic Profile: Maximum Plasma Concentration (Cmax)
Cmax was determined from the maximum plasma concentration from Day 0 (post veledimex and resection/craniotomy), 3-5 hours after the veledimex dose on Day 1, and 3-5 hours after the veledimex dose on Day 14.
Measured: Day 0 to Day 15 (Day 14 24-hour post dose)
Veledimex Pharmacokinetic Profile: Time to Maximum Plasma Concentration (Tmax)
Tmax was determined from the time of maximum plasma concentration from Day 0 (post veledimex and resection/craniotomy), 3-5 hours after the veledimex dose on Day 1, and 3-5 hours after the veledimex dose on Day 14.
Measured: Day 0 to Day 15 (Day 14 24-hour post dose)
Veledimex Pharmacokinetic Profile: Half-life (t1/2)
t1/2 was determined from the plasma concentrations measured from Day 0 (post veledimex and resection/craniotomy) through Day 15 (24 hours post Day 14 dose)
Measured: Day 0 to Day 15 (24 hours post Day 14 dose)
Veledimex Pharmacokinetic Profile: Area Under the Concentration-versus-time Curve (AUC)
AUC was determined from the plasma concentrations measured from Day 0 (post veledimex and resection/craniotomy) through Day 15 (24 hours post Day 14 dose)
Measured: Day 0 to Day 15 (Day 14 24-hour post dose)
Veledimex Pharmacokinetic Profile: Volume of Distribution (Vd)
Vd was determined from the plasma concentrations measured from Day 0 (post veledimex and resection/craniotomy) through Day 15 (24 hours post Day 14 dose).
Measured: Day 0 to Day 15 (Day 14 24-hour post dose)
Veledimex Pharmacokinetic Profile: Clearance (CL)
CL was determined from the plasma concentrations measured from Day 0 (post veledimex and resection/craniotomy) through Day 15 (24 hours post Day 14 dose).
Measured: Day 0 to Day 15 (Day 14 24-hour post dose)
Veledimex Concentration Ratio Between the Brain Tumor and the Blood.
Tumor/plasma ratio at Day 0 by cohort
Measured: 1 day (Day 0 at time of resection)
Cumulative Dexamethasone Use During Days 0-14
To assess concomitant corticosteroid use during the first treatment cycle, the cumulative dose of dexamethasone administered to each subject from Day 0 to Day 14 was calculated. This measure reports the mean cumulative dose in milligrams (mg) for each cohort
Measured: Days 0 through 14
