Purpose

This phase I trial studies the side effects and best dose of tinostamustine (EDO-S101) given with or without radiation therapy in treating patients with newly diagnosed MGMT-unmethylated glioblastoma. Tinostamustine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth in patients with glioblastoma.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To characterize the safety profile and determine the maximum tolerated dose (MTD) of
      tinostamustine (EDO-S101) in the adjuvant phase of therapy for patients with newly diagnosed
      MGMT-promoter unmethylated glioblastoma (GB) post chemoradiation with temozolomide. (Stage 1)
      II. To characterize the safety profile and determine the MTD of EDO-S101 when given as a
      single agent in the concomitant phase with radiation therapy (RT) in patients with newly
      diagnosed GB who are O6-methylGuanine deoxyribonucleic acid (DNA) methyltransferase
      (MGMT)-promoter unmethylated. (Stage 2) III. To confirm the MTD of EDO-S101 in the
      concomitant phase and adjuvant phase in an expanded population of newly diagnosed GB patients
      who are MGMT-promoter un-methylated. (Dose Expansion Group)

      SECONDARY OBJECTIVES:

      I. To assess anti-tumor activity for patients with newly diagnosed GB who are MGMT-promoter
      unmethylated based on progression-free survival (PFS), overall survival (OS), and overall
      response rate (ORR).

      EXPLORATORY OBJECTIVES:

      I. Profiling tumor DNA, messenger ribonucleic acid (mRNA), microRNA and epigenetic profiling
      (DNA methylation) and evaluation of whole exome sequencing, RNA sequencing, microRNA
      sequencing and cell-free circulating tumor DNA (ctDNA) and correlate with outcome.

      OUTLINE: This is a dose escalation study of tinostamustine. Patients who have completed
      temozolomide (TMZ) and radiation therapy (RT) are assigned to Stage 1A or Stage 1B. Patients
      who have received no treatment other than surgery are assigned to Stage 2.

      STAGE 1A: Patients receive tinostamustine intravenously (IV) over 30 minutes on day 1.
      Treatment repeats every 21 days for up to 12 cycles in the absence of disease progression or
      unacceptable toxicity.

      STAGE 1B: Patients receive tinostamustine IV over 30 minutes on days 1 and 15. Treatment
      repeats every 28 days for up to 12 cycles in the absence of disease progression or
      unacceptable toxicity.

      STAGE 2: Patients undergo RT 5 days a week for up to 6 weeks in the absence of disease
      progression or unacceptable toxicity. Patients also receive tinostamustine IV on day 1 or
      days 1 and 15 (to be determined following stage 1). Treatment repeats every 21 days (day 1)
      or 28 days (days 1 and 15) for up to 12 cycles in the absence of disease progression or
      unacceptable toxicity.

      After completion of study treatment, patients are followed up at 30 days and then every 3
      months.

          -  Female subjects of childbearing potential should have a negative serum pregnancy test
             within 72 hours of starting first dose of study drug.

          -  Female subjects of childbearing potential should be willing to use 2 methods of birth
             control or be surgically sterile, or abstain from heterosexual activity for the
             duration of the study. Subjects of childbearing potential are those who have not been
             surgically sterilized or have not been free from menses for > 1 year.

          -  Male subjects should agree to use an adequate method of contraception during the
             course of the study.

          -  Patients must have completed standard radiation therapy with concurrent TMZ and must
             not have evidence of progressive disease on post treatment imaging. Progression can
             only be defined using diagnostic imaging if there is new enhancement outside of the
             radiation field (beyond the high-dose region or 80% isodose line) or if there is
             unequivocal evidence of viable tumor on histopathologic sampling (e.g., solid tumor
             areas [i.e, > 70% tumor cell nuclei in areas], high or progressive increase in MIB-1
             proliferation index compared with prior biopsy, or evidence for histologic progression
             or increased anaplasia in tumor). Note: Given the difficulty of differentiating true
             progression from pseudoprogression, clinical decline alone, in the absence of
             radiographic or histologic confirmation of progression, will not be sufficient for
             definition of progressive disease in the first 12 weeks after completion of concurrent
             chemoradiotherapy. (For Stage 1: post-chemoradiation group only)

          -  Prescribed treatment with concomitant temozolomide must be consistent with the Food
             and Drug Administration (FDA) package insert. The dose must be 75 mg/m^2 daily for the
             6 to 6.5 weeks of radiation therapy. If the patient missed more than 1 week of
             temozolomide dosing during radiotherapy, then they are not eligible for the trial.
             EDO-S101 can accentuate thrombocytopenia induced by temozolomide. Therefore, if
             patients had a platelet < 75,000/mm^3 during concomitant temozolomide therapy during
             radiation, they are not eligible for this trial

               -  NOTE: Complete blood count (CBC) should be monitored during chemoradiation and
                  lowest platelet count must be submitted at registration. (For stage 1:
                  post-chemoradiation group only)

          -  Patients must have undergone surgery of their GBM, and must not have had any further
             treatment following surgery. A minimal interval of 7 days between the day of surgery
             and the day of inclusion should be respected; a maximal interval of 31 days between
             the day of surgery and the day of inclusion should be respected; the patient should
             have fully clinically recovered from the surgery. (For stage 2: radiation with
             concurrent and adjuvant EDO-S101 only)

          -  Patients must undergo surgery and must not have further treatment. (For MTD expansion
             cohort only)

        Exclusion Criteria:

          -  Has received prior interstitial brachytherapy, implanted chemotherapy, or therapeutics
             delivered by local injection or convection enhanced delivery. Prior treatment with
             Gliadel wafers will be excluded. Concomitant use of the Optune device will also be
             excluded.

          -  Is currently participating or has participated in any other any other investigational
             or therapeutic trial before or after chemoradiation.

          -  Any serious medical condition that interferes with adherence to study procedures.

          -  Has had prior chemotherapy, targeted small molecule therapy, within 2 weeks prior to
             study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse
             events due to a previously administered agent. Note: subjects with =< grade 2
             neuropathy are an exception to this criterion and may qualify for the study. Note: if
             subject received major surgery, they must have recovered adequately from the toxicity
             and/or complications from the intervention prior to starting therapy. (For Stage 1:
             post-chemoradiation group only)

          -  Patients with a history of a second malignancy diagnosed within three (3) years of
             study enrollment or have a known additional malignancy that is progressing or requires
             active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell
             carcinoma of the skin, or in situ cervical cancer that has undergone potentially
             curative therapy.

          -  New York Heart Association (NYHA) stage III/IV congestive heart failure, arrhythmias
             not adequately controlled.

          -  Patients with prolonged corrected QT (QT) interval defined as male > 450 msec and
             female > 470 msec.

          -  Patients who are on treatment with drugs known to prolong the QT/QTc interval. Case of
             the selective serotonin reuptake inhibitors (SSRIs): Patients treated with a SSRI AND
             displaying a QTc prolongation are NOT eligible in the trial. Nevertheless, there is no
             need to stop or change a SSRI if a patient is on a stable dose AND with no impact on
             QT/QTc interval, since it is not expected that plasma concentration of the SSRI will
             be affected by the administration of EDO-S101

          -  Has known gliomatous meningitis, extracranial disease, or multifocal disease. Subject
             has multifocal GBM, defined as discrete sites of contrast enhancing disease without
             contiguous T2/fluid-attenuated inversion recovery (FLAIR) abnormality that require
             distinct radiotherapy ports. Satellite lesions that are associated with a contiguous
             area of T2/FLAIR abnormality as the main lesion(s) and that are encompassed within the
             same radiotherapy port as the main lesion(s) are permitted.

          -  Has an ongoing or previous history of spontaneous intratumoral hemorrhage.

          -  Has a history or current evidence of any condition, therapy, or laboratory abnormality
             that might confound the results of the trial, interfere with the subject's
             participation for the full duration of the trial, or is not in the best interest of
             the subject to participate, in the opinion of the treating investigator.

          -  Has known psychiatric or substance abuse disorders that would interfere with
             cooperation with the requirements of the trial.

          -  Is pregnant or breastfeeding, or expecting to conceive or father children within the
             projected duration of the trial, starting with the screening visit.

          -  Has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies).
             Testing not required.

          -  Has known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or
             hepatitis C (e.g., hepatitis C virus (HCV) RNA [qualitative] is detected). (Testing

          -  Use of any drug with histone deacetylase (HDAC) inhibiting activity.

          -  Use of valproate in any of its indications (epilepsy, mood disorder). Valproate, due
             to its HDAC inhibiting activity is contraindicated. For those patients on valproate,
             valproate will need to be discontinued and switched to a different anti-epileptic
             agent or psychotropic agent. A washout period of 4 days from valproate acid will be
             allowed prior to enrolling into the trial.

          -  Patients who missed more than 1 week of temozolomide dosing during radiotherapy. (For
             Stage 1: Post-chemoradiation group only)

          -  Patients who had a platelet < 75,000/mm^3 during concomitant temozolomide therapy
             during radiation. (For Stage 1: Post-chemoradiation group only)

Maximum Eligible Age:N/A
Minimum Eligible Age:18 Years
Eligible Gender:All
Healthy Volunteers:No

Primary Outcome Measures

Measure:Maximum tolerate dose (MTD) (Stages 1 & 2)
Time Frame:Up to 4 weeks
Safety Issue:
Description:Defined by dose limiting toxicity (DLT). Toxicity will be evaluated according to the most current version of the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) toxicity criteria. The MTD is confirmed when six (6) patients are treated at a dose level with less than two (2) DLTs.

Secondary Outcome Measures

Measure:Incidence of adverse events (Stage 1)
Time Frame:Up to 2 years
Safety Issue:
Description:Graded according to CTCAE version 4.0. Toxicity monitoring will be conducted using Bayesian continuous monitoring, where the toxicity evaluation endpoint is defined as treatment-related unmanageable toxicities, including grade >= 3 AEs that require termination of the treatment during cycle one. Toxicity rate of 30% or higher will be considered unacceptable. The overall toxicity rate will be summarized by frequency and 95% confidence interval. Adverse Events will be tabulated by grade and by their relationship to the treatment.
Measure:Objective response rate (ORR) (Stage 2)
Time Frame:Up to 2 years
Safety Issue:
Description:The ORR will be summarized by frequency and 95% confidence interval. Logistic regression will be used to explore the correlation between response rates.
Measure:Overall survival (OS) (Stage 2)
Time Frame:Up to 2 years
Safety Issue:
Description:Kaplan-Meier curves will be generated and median survival time will be derived for OS. Cox proportional hazard regression will be employed for multivariate analysis on time-to-event outcomes with factors.
Measure:Progression-free survival (PFS) (Stage 2)
Time Frame:Up to 2 years
Safety Issue:
Description:Kaplan-Meier curves will be generated and median survival time will be derived for PFS. Cox proportional hazard regression will be employed for multivariate analysis on time-to-event outcomes with factors.
