NCT05691491

Brief Summary

This phase I/II trial studies the side effects and best dose of temozolomide and M1774 and how well they works in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and may have spread to nearby tissue, lymph nodes, or distant parts of the body (advanced). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells and slow down or stop tumor growth. M1774 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Adding M1774 to temozolomide may shrink or stabilize cancer for longer than temozolomide alone.

Outcome Measures

Primary Outcomes (1)

  • Dose limiting toxicity and the maximum tolerated dose

    Defined as adverse events meeting the criteria that are at least "possibly related" to TMZ or M1774. Dose limiting toxicity for temozolomide in combination with M1774 and the maximum tolerated dose or maximum safe dose. Will consider ten dose levels (dose level -2, -1, 1, 2, 3, 4, 5, 6, 7, 8). The Bayesian Optimal Interval (BOIN) design based on the cumulative number of patients who experience a dose-limiting toxicity (DLT) at the current dose level will be used to guide dose escalation.

    Up to 28 days

Secondary Outcomes (4)

  • Objective response rate (ORR)

    Up to 2 years

  • Progression free survival (PFS)

    From start of treatment to time of progression or death, whichever occurs first, assessed up to 2 years

  • Overall survival (OS)

    Up to 2 years

  • Rate of >= grade 3 adverse events (AE)

    Up to 2 years

Study Arms (1)

Treatment (tuvusertib, temozolomide)

EXPERIMENTAL

Patients receive tuvusertib PO QD) on days 1-7 and temozolomide PO QD on days 1-5 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan and MRI as well as collection of blood samples throughout the trial. Patients also undergo a biopsy at baseline and may undergo one on study and/or at time of progression.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must have histologically or cytologically confirmed diagnosis of metastatic advanced cancer.
  • In dose escalation, any solid tumor patients with either O6-methylguanine DNA methyltransferase (MGMT) promoter hypermethylation positivity on testing / pre-screening of archival tissue OR an extracranial solid tumor where TMZ is considered a standard of care per National Comprehensive Cancer Network (NCCN) guidelines (neuroendocrine tumor, small cell lung cancer, melanoma or soft tissue sarcoma). The tumor lesion must be safely accessible to a mandatory biopsy. Patients with MGMT promoter hypermethylated colorectal cancer must be mismatch repair proficient / microsatellite stable.
  • In phase 2, only patients with mismatch repair proficient / microsatellite stable colorectal cancer that have MGMT promoter hypermethylation positivity on pre-screening of archival tissue will be eligible.
  • In dose escalation, patients must have progressed after treatment with all available therapies including immunotherapies for metastatic disease that are known to confer clinical benefit, or are intolerant to treatment, or refuse standard treatment. Patients may not have previously received temozolomide or an ataxia telangiectasia and rad3-related (ATR) inhibitor.
  • For patients with mismatch repair proficient / microsatellite stable colorectal cancer in the phase 2 portion, patients must have received prior therapy with 1 or more systemic therapies in the metastatic setting that includes 5-fluorouracil, irinotecan, and oxaliplatin. Patients with microsatellite stable colorectal cancer (mCRC) need to have had exposure, unless contraindicated, to all 3 of oxaliplatin, irinotecan, and fluoropyrimidine (FP).
  • The use of 5-fluorouracil and oxaliplatin in the adjuvant setting is acceptable, provided the development of metastatic disease was less than 6 months after the completion of adjuvant therapy.
  • Patients with a prior hypersensitivity reaction to oxaliplatin in the adjuvant setting do not require retreatment in the metastatic setting.
  • Age \>=18 years. Because no dosing or adverse event data are currently available on the use of M1774 in combination with temozolomide in patients \< 18 years of age, children are excluded from this study.
  • Measurable disease on CT and/or MRI per Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria.
  • Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (or Karnofsky \>= 60%).
  • Hemoglobin \>=10 g/dL (No blood transfusions are allowed within 14 days of cycle 1 day 1 \[C1D1\]).
  • White blood cells (WBC) \> 3 x 10\^9/L.
  • Absolute neutrophil count \>= 1,500/mcL.
  • Platelets \>= 100,000/mcL.
  • Total bilirubin =\< 1.5 x institutional upper limit of normal (ULN).
  • +10 more criteria

You may not qualify if:

  • Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities \> grade 1) with the exception of alopecia and neuropathy, which may be =\< grade 2.
  • History of allergic reactions or hypersensitivity attributed to compounds of similar chemical or biologic composition to M1774 or temozolomide, including dacarbazine.
  • Patients with uncontrolled intercurrent illness.
  • Pregnant women are excluded from this study because M1774 is an ATR inhibiting agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with M1774 breastfeeding should be discontinued if the mother is treated with M1774. These potential risks also apply to temozolomide.
  • Patients with a prior history of ataxia telangiectasia.
  • Patients who are not able to swallow orally administered medication or have gastrointestinal disorders likely to interfere with absorption of the study medication.
  • Patients who cannot discontinue proton-pump inhibitors (PPIs) while taking M1774. H-2 receptor antagonists are allowed but should not be taken within 12 hours before or 2 hours after M1774. Antacids are also allowed, but should not be taken 2 hours before 2 hours after M1774.
  • Extensive RT involving greater than 30% of the bone marrow is not permitted during the study.
