Study Endpoints

Primary Endpoints

Median Overall Survival (OS) of Subjects Receiving Td pre-conditioning
5 years

OS is defined as the time in months between randomization and death, or last follow-up if alive (Groups 1 and 2). Kaplan-Meier methods will be used to estimate median OS

Safety of administering Varlilumab to GBM patients receiving temozolomide and dendritic cell vaccines ± Td pre-conditioning as measured by the percentage of patients with unacceptable toxicity regardless of attribution
5 years

Percentage of patients with unacceptable toxicity (all Groups)

Median percent change between baseline, assessed on day 14, and nadir levels of Treg before the time that the second cycle of adjuvant TMZ would be administered. Treg determined by flow cytometry (CD3+ CD4+ CD25+ Foxp3+).
50 days

Change between baseline and nadir before the 2nd cycle of TMZ (Combined Groups 1 and 2, Group 3)

Secondary Endpoints

Median Overall Survival (OS) of Subjects Receiving DC vaccines, varlilumab, and Td pre-conditioning
5 years
Median Progression-free Survival (PFS)
5 years
Median Chemokine (C-C motif) ligand 3 (CCL3) Levels in Serum at 24, 48, and 72 hours after Pre-conditioning

Treatment Arms

ArmTypeDescription
Gr1: DC vaccine (DC pre-conditioning)EXPERIMENTALPatients will receive TMZ at a target dose of 150-200 mg/m\^2/d for 5 days every 4 (+2) weeks for up to 12 cycles. DC vaccines will be administered in equal amounts to both inguinal regions. DC vaccines #1-3 occur every 2 weeks and all subsequent vaccines (up to 10) occur monthly. Group 1 patients will receive autologous unpulsed DC vaccines administered to a single side of the groin and saline administered to the contralateral side the day prior to the 4th DC vaccine as pre-conditioning.
Gr2: DC Vaccine (Td pre-conditioning)EXPERIMENTALPatients will receive TMZ at a target dose of 150-200 mg/m\^2/d for 5 days every 4 (+2) weeks for up to 12 cycles. DC vaccines will be administered in equal amounts to both inguinal regions. DC vaccines #1-3 occur every 2 weeks and all subsequent vaccines (up to 10) occur monthly. Group 2 patients will receive a single dose of Td toxoid administered to a single side of the groin and saline administered to the contralateral side the day prior to the 4th DC vaccine, which is always given bilaterally at the groin site.
Gr3:DC Vaccine+varlilumab(Td pre-conditioning)EXPERIMENTALPatients will receive TMZ at a target dose of 150-200 mg/m\^2/d for 5 days every 4 (+2) weeks for up to 12 cycles. DC vaccines will be administered in equal amounts to both inguinal regions. DC vaccines #1-3 occur every 2 weeks and all subsequent vaccines (up to 10) occur monthly. Group 3 patients will receive the first 3 DC vaccines every 2 weeks, same as Groups 1 and 2, but they will also receive varlilumab intraveneously (IV) 7 days before vaccine #1 and again at the same visit as vaccine #1, as well as 7 days before every DC vaccine except vaccine #2. Prior to the 4th vaccine, patients will receive a single dose of Td toxoid administered to a single side of the groin and saline administered to the contralateral side.

Interventions

NameTypeDescription
Human CMV pp65-LAMP mRNA-pulsed autologous DCsBIOLOGICAL2x10\^7 human CMV pp65-LAMP mRNA-pulsed autologous DCs are given intradermally and bilaterally at the groin site (divided equally to both inguinal regions). Patients will receive up to a total of 10 DC vaccines.
TemozolomideDRUGTemozolomide is a standard chemotherapy given to all enrolled patients at a targeted dose of 150-200mg/m2/d for 5 days every 4 (+ 2) weeks for up to 12 cycles (patients with unmethylated MGMT gene promoter will receive only cycle 1)
VarlilumabBIOLOGICALVarlilumab is an agonist anti-CD27 monoclonal antibody
TdBIOLOGICALA single dose of Td toxoid (1 flocculation unit, Lf, in 0.4 mLs) administered to a single side of the groin given intradermally
Unpulsed DCsBIOLOGICALPatients in Group I will receive 1 x 10\^6 autologous unpulsed DCs in saline administered to a single side of the groin intradermally 1 day before the fourth vaccine.

Frequently asked questions about Human CMV pp65-LAMP mRNA-pulsed autologous DCs

What is Human CMV pp65-LAMP mRNA-pulsed autologous DCs used for?

Human CMV pp65-LAMP mRNA-pulsed autologous DCs is an investigational cell therapy being studied for the treatment of glioblastoma, a type of brain cancer. It is currently in Phase 2 clinical development and is not yet approved by regulatory authorities.

Who is developing Human CMV pp65-LAMP mRNA-pulsed autologous DCs?

Human CMV pp65-LAMP mRNA-pulsed autologous DCs is being developed by Celldex Therapeutics, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol CLDX. The company is conducting clinical trials to evaluate this investigational therapy in patients with glioblastoma.

What phase is Human CMV pp65-LAMP mRNA-pulsed autologous DCs in?

Human CMV pp65-LAMP mRNA-pulsed autologous DCs is currently in Phase 2 clinical development. It is an investigational therapy, meaning it has not been approved by the FDA or other regulatory agencies and is still being evaluated for safety and efficacy in clinical trials.

What clinical trials is Human CMV pp65-LAMP mRNA-pulsed autologous DCs in?

Human CMV pp65-LAMP mRNA-pulsed autologous DCs is being studied in a Phase 2 clinical trial registered as NCT03688178. This trial is titled 'DC Migration Study to Evaluate TReg Depletion In GBM Patients With and Without Varlilumab' and is actively enrolling patients with glioblastoma in the United States.

Is Human CMV pp65-LAMP mRNA-pulsed autologous DCs the same as varlilumab?

No, Human CMV pp65-LAMP mRNA-pulsed autologous DCs is not the same as varlilumab. The clinical trial NCT03688178 is evaluating the combination of these two investigational therapies in patients with glioblastoma. Varlilumab is a separate monoclonal antibody being studied for its potential to enhance the immune response.
