Outcome Measures

Primary Outcomes (2)

  • Phase 1: Number of Participants with first-cycle dose limiting toxicity

    Time interval between the first dose administration in Cycle 1 and the first dose administration in Cycle 2 which is expected to be 28 days or up to 42 days in case of dose delay due to drug related toxicity

  • Phase 2: Objective Response Rate

    Objective Response Rate (ORR), calculated as the proportion of evaluable patients who have achieved, as best overall response (BOR), confirmed complete response (CR) or partial response (PR) through central retrospective assessment of RANO criteria

  • Terminal elimination half-life (t1/2) of NMS-03305293 and possible identified metabolites (if appropriate) after single and multiple doses of drug

    Phase 1 and backfill cohorts: Cycle 1 (each cycle is 28 days) on Days 1, 2, 5, 6 and 8; Cycle 2 on Days 5 and 15 (day 15 only if 28 days schedule). Phase 2: Cycle 1 (Days 1 and 5), Cycle 2 (Day 5) and Cycle 3 or Cycle 4 (Day 5)

  • +15 more secondary outcomes

Study Arms (1)

NMS-03305293 +TMZ

EXPERIMENTAL

Phase 1 Dose Escalation: All patients will receive NMS-03305293 and temozolomide (TMZ) administered orally (NMS-03305293 once or twice daily on days 1-7 or 28 consecutive days from Day 1 to Day 28; TMZ once daily on days 1-5;) in repeated 4-week cycles aimed at defining the Maximum Tolerated Dose (MTD) and the Recommended Phase 2 Doses (RP2Ds) of NMS-03305293 in combination with TMZ. Each cycle is 28 days. Phase 2: Once the RP2D is defined, the patients will receive TMZ daily on days 1-5 in combination with NMS-03305293 at the RP2D on days 1-7 or on days 1-28 every 28 days. Backfill cohorts: additional patients may be treated with TMZ daily on days 1-5 and NMS-03305293 at different dose levels/schedules that have been previously assessed and determined to be safe, in order to properly characterize the exposure relationship over a range of doses/schedules. The backfill cohorts may run in parallel.

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Phase 1
  • Histologically confirmed diagnosis of an intracranial diffuse glioma (i.e. diffuse astrocytoma, oligodendroglioma or glioblastoma). Sponsor may opt to restrict enrollment based on MGMT status, tumor type, tumor measurability or apply restriction on time to first relapse.
  • Patients at first radiographic relapse after chemotherapy including temozolomide as long as no more than 12 cycles of temozolomide were administered.
  • Patients may have been operated for recurrence. If operated:
  • residual and measurable disease after surgery is not required but pathology must have confirmed tumor recurrence.
  • a post-surgery MRI should be available within 48 hours following surgery.
  • surgery completed at least 2 weeks before enrolment and patient clinical status should not be worsened respect to pre-surgery condition
  • Backfill cohorts
  • Histologically confirmed diagnosis of Glioblastoma, IDH-wildtype as per WHO 2021 classification, including IDH-wildtype diffuse and astrocytic glioma in adults if there is microvascular proliferation or necrosis or TERT promoter mutation or EGFR gene amplification or +7/-10 chromosome copy number changes or c-IMPACT-NOW 3 definition including diffuse astrocytic glioma, IDH-wildtype, with molecular features of glioblastoma, WHO Grade 4. IDH1 status must be assessed locally by immunohistochemistry (IHC). If IHC is performed and is negative, and patient is \< 55 years old, sequencing or a PCR-based validated test must be performed to exclude other IDH1 or IDH2 most frequent mutations. Sponsor may opt to restrict enrollment based on MGMT status or apply restriction on time to first relapse.
  • Patients must have measurable disease and meet standard of care resection, if indicated, and irradiation, if indicated, with concomitant temozolomide plus up to 6 cycles of adjuvant temozolomide consistent with local standards of care.
  • Patients may have been operated for recurrence. If operated:
  • residual and measurable disease after surgery is required
  • a post-surgery MRI should be available within 48 hours following surgery
  • surgery completed at least 2 weeks before enrolment and patient clinical status should not be worsened respect to pre-surgery condition.
  • Phase 2
  • +20 more criteria

You may not qualify if:

  • Current enrollment in another interventional clinical trial.
  • Current treatment with other anticancer agents or devices, or treatment at recurrence with carmustine wafer implants and proteasome inhibitors.
  • Previous treatment with PCV (procarbazine, lomustine and vincristine) or any of its components, carmustine wafer implants, or bevacizumab.
  • Previous treatment with PARP inhibitors.
  • Major surgery, other than surgery for recurrent diffuse glioma, within 4 weeks prior to treatment.
  • Standard radiotherapy within the three months (12 weeks) prior to the diagnosis of progression unless the progression is clearly outside the radiation field (eg, beyond the high-dose region or 80% isodose line) or unless the recurrence is histologically proven.
  • Prior radiotherapy with a dose over 65 Gy, stereotactic radiosurgery or brachytherapy, unless the recurrence is histologically proven.
  • Use of full-dose anticoagulants unless the INR or aPTT is within therapeutic limits (according to the medical standard in the institution) and the patient has been on a stable dose of anticoagulants for at least two weeks before enrollment
  • Treatment with concomitant medications known to be sensitive substrates of CYP2D6 and CYP2C19 that cannot be replaced with another treatment.
  • Treatment with enzyme-inducing anti-epileptic drugs (EIAED). Patients may be on non-EIAED or not be taking any anti-epileptic drugs. Patients previously on EIAED must be fully switched to non-EIAED at least 2 weeks prior to enrolment.
  • Pregnant or breast-feeding women.
  • Known hypersensitivity to any component of NMS-03305293 or TMZ drug formulations.
  • Known active infections (bacterial, fungal, viral including HIV positivity) requiring systemic treatment.
  • Patients with QTc interval ≥460 milliseconds for women, ≥450 milliseconds for men or with risk factors for torsade de pointes (e.g., uncontrolled heart failure, uncontrolled hypokalemia, history of prolonged QTc interval or family history of long QT syndrome). For patients receiving treatment with concomitant medications known to prolong the QTc interval, replacement with another treatment prior to enrollment is mandatory. If concomitant use of anti-emetics is considered essential for the care of the patients, instruction in protocol will be followed.
  • Active gastrointestinal disease (e.g., documented gastrointestinal ulcer, Crohn's disease, ulcerative colitis, or short gut syndrome) or other syndromes that would impact on drug absorption.
