Peptide Targets for Glioblastoma Against Novel Cytomegalovirus Antigens (PERFORMANCE)

June 7, 2022 updated by: Eric Thompson, M.D.
Newly diagnosed glioblastoma (GBM) patients with complete or partial surgical resection who were CMV seropositive patients were eligible to enroll on this trial. Patients were enrolled following standard of care chemoradiation and prior to initiation of post-radiation cycles of temozolomide (TMZ) provided they met all eligibility criteria. All eligible patients received a tetanus-diphtheria (Td) vaccination. Patients enrolled on study were randomized to receive either standard TMZ or dose-intensified TMZ (excluding the safety cohort who only received standard TMZ). All patients received a pre-conditioning injection of tetanus on day 22 of the first post-radiation cycle of TMZ. The following day, patients received the first of 3 intradermal (i.d.) injections of the study drug cytomegalovirus peptide (PEP-CMV), which contained either a combination of Component A and Component B or Component A only depending upon when they enrolled on study. Vaccines #2 and #3 will be given at 2 week intervals. Patients who were O[6]-methylguanine-DNA methyltransferase (MGMT) unmethylated received one adjuvant cycle of the TMZ regimen according to their assigned TMZ arm. Patients who were MGMT methylated or whose methylation status was inconclusive continue with up to 12 cycles of TMZ. After the completion of a patient's last TMZ cycle, vaccines continued every 4-6 weeks for a maximum number of 20 vaccines (unless tumor progression occurred). The study ended prematurely due to lack of funds. The preliminary results suggest that the vaccine may be capable of generating an immune response.

Study Overview

Detailed Description

Patients were enrolled following radiation therapy and prior to initiation of post-radiation therapy cycles of adjuvant TMZ provided they met all eligibility criteria. After signing main consent, patients had immune monitoring blood work collected and received a Tetanus-diphtheria booster vaccination with 0.5 mL of Td (tetanus, diphtheria toxoid, adsorbed). After meeting all eligibility criteria, patients were randomized to receive either standard TMZ (150-200 mg/m^2/day on days 1-5 of each 28-day cycle) with vaccination on Day 23 (-1 day, + 2 days) of each TMZ cycle or to receive dose-intensified TMZ (75-100 mg/m^2/day on days 1-21 of each 28-day cycle) with vaccination on day 23 (-1 day, +2 days) of each TMZ cycle (excluding patients enrolled in the safety cohort who only received standard TMZ).

Patients began their initial cycle of adjuvant TMZ as soon as possible following randomization, if applicable. For Arm 1, the adjuvant TMZ cycle(s) will be given as described above. If a patient had an MGMT unmethylated tumor, they discontinued TMZ after the 1st cycle.

All patients received a tetanus pre-conditioning injection in the right groin on day 22 (+1 day) of cycle 1 of adjuvant TMZ. On the following day, patients receive their study vaccine (either a combination of Component A and Component B or Component A only depending upon when they enrolled on study).

Vaccines #2 and #3 were given at 2 week intervals (+ 3 days), which will resulted in a ~35-day delay before starting TMZ cycle 2. MGMT unmethylated patients did not receive subsequent cycles of TMZ, but continued to receive vaccines approximately every 4 (+2) weeks. Originally, patients received the vaccine as follows: 500 µg of PEP-CMV Component A mixed with Montanide Incomplete Freund's Adjuvant (ISA)-51 intradermally administered in the right groin and 2 hours later, 500 µg of PEP-CMV Component B mixed in 150 µg of Granulocyte Macrophage Colony Stimulating Factor (GM-CSF) intradermally administered in the left groin. A safety cohort was added in 2017 following hypersensitivity reactions in which patient received different schedules of vaccine Components A and B to determine the source of the hypersensitivity reactions. Following this safety cohort, the randomized study was allowed to reinitiate with changes to vaccine administration procedure.

Subsequent revisions were made to the study in the latter part of 2018, due to a continuation of hypersensitivity reactions, and Component B was removed from the study. Patients then received the vaccine as follows: 500 µg of PEP-CMV Component A mixed with Montanide ISA-51 administered intradermally with half in the right groin and half in the left groin.

Patients were imaged with contrast-enhanced magnetic resonance imaging (MRI) within 2 weeks (+3 days) after vaccine 3 and then approximately every 8 weeks. RANO criteria was used for assessment of pseudo-progression, and patients demonstrating definitive progression were removed from study. Blood for immune monitoring was obtained at several time points.

The study ended prematurely due to lack of funds.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Treatment-related Adverse Events
Time Frame: 2 weeks after the 3rd vaccine, which is approximately 12 weeks after consent
To assess the safety of PEP-CMV vaccination in combination with adjuvant TMZ, the percentage of patients with unacceptable toxicity will be estimated within each arm. All patients who received any PEP-CMV vaccine will be included in these analyses.
2 weeks after the 3rd vaccine, which is approximately 12 weeks after consent
Immunologic Response as Measured by Peak Number of T Cells That Secrete IFNγ by ELISPOT in Response to Component A of PEP-CMV
Time Frame: Through study completion, an average of 1.5 years

The primary analysis will focus on patients who have follow-up immunologic monitoring after the 3rd vaccination with component A alone and before initiation of the second TMZ/vaccine cycle. Such a patient is considered "evaluable" for the immunologic response primary analyses.

The Wilcoxon rank sum test will compare treatment groups with regard to the median peak number of T cells that secrete IFNγ by ELISPOT in response to component A of PEP-CMV. Analyses will include only those patients who have an assessment of immune response after receiving 3 vaccinations.

Through study completion, an average of 1.5 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Antigen Loss
Time Frame: Through study completion, an average of 1.5 years
To determine if tumors are CMV antigen negative by immunohistochemical analysis for the presence of the antigen pp65 at the time of disease progression/recurrence
Through study completion, an average of 1.5 years
