Brief Summary:
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 id 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 O6-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 patients 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
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 05 mL of Td tetanus diphtheria toxoid adsorbed After meeting all eligibility criteria patients were randomized to receive either standard TMZ 150-200 mgm2day 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 mgm2day 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 cycles 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 Freunds 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
