NCT07277413 | RECRUITING | NSCLC Adenocarcinoma

A Study of IDE892 as Monotherapy and Combination in MTAP-deleted Advanced Solid Tumors
Sponsor:

IDEAYA Biosciences

Brief Summary:

This is a multicenter clinical study to evaluate the safety, efficacy, and Pharmacokinetics (PK) of IDE892 as monotherapy and in combination with other agents including IDE397 in participants with methylthioadenosine phosphorylase (MTAP)-deleted advanced solid tumors within indications of interest.

Condition or disease

Squamous Cell Car. - Esophagus

Urothelial Carcinoma (UC)

Bladder Cancer

Mesothelioma

Pleural Mesothelioma

Phase

PHASE1

Detailed Description:

The purpose of this study is to evaluate safety, efficacy, and PK of IDE892 as monotherapy and combination therapy in adult participants with MTAP-deleted tumors who have progressed after standard therapy and represent a high unmet need. In the current stage, the combination will be focused on IDE892 with IDE397, an oral inhibitor of methionine adenosyltransferase 2A (MAT2A), to fully exploit the vulnerabilities associated with methylthioadenosine (MTA) accumulation in MTAP-deleted tumors while maintaining a substantial therapeutic index. The mechanistic rationale for this study is discussed in the following sections.

Accepts Healthy Volunteers:
Criteria
Inclusion Criteria
  • * Are ≥ 18 years of age at the time of signing the ICF.
  • * Have a histologically confirmed diagnosis of a locally advanced recurrent or metastatic solid tumor type of interest with MTAP deletion (for dose escalation: mesothelioma \[pleural or peritoneal\], gastroesophageal cancers \[squamous and adenocarcinoma of esophagus, gastric adenocarcinoma, gastroesophageal junction cancers\], NSCLC \[adenocarcinoma, squamous cell carcinoma, and adeno-squamous\] and UC \[including mixed urothelial-squamous histology\]; for dose expansion: NSCLC that has progressed on at least one prior line of treatment and for which additional effective standard therapy is not available or for which the participant is not a candidate due to intolerance).

Exclusion Criteria
  • * Known symptomatic brain metastases requiring supraphysiologic doses of systemic corticosteroids
  • * Have a known primary central nervous system (CNS) malignancy
  • * Have had other malignancies within 2 years prior to the first dose, with some exceptions
  • * Impaired cardiac function or clinically significant cardiac diseases
  • * Have presence of uncontrolled pleural, peritoneal, or pericardial effusion within 2 weeks before the first study dose, requiring recurrent drainage procedures or an indwelling drainage catheter
  • * Have a history of severe infections within 4 weeks prior to the start of study treatment
  • * Hypertension (e.g., \> 150/100 mmHg) that cannot be controlled by medications despite optimal medical therapy
  • * Other acute or chronic medical or psychiatric condition
  • * Have a history of immunodeficiency, with a positive human immunodeficiency virus(HIV) test at screening
  • * Known or suspected viral hepatitis
  • * Had an adverse reaction to a previous antitumor treatment that has not recovered to CTCAE Grade ≤ 1
  • * Have received chemotherapy within 3 weeks of the first dose of IMP; immunotherapy or biologic targeted antitumor treatments within 2 weeks before the first dose of IMP; small molecule inhibitors within 2 weeks before the first dose of IMP, or other investigational products within 4 weeks
  • * Current radiation-related toxicity or radiation therapy within 2 weeks before the first dose of IMP
  • * Administration of any of the following within 2 weeks before the first dose of IDE892 as a monotherapy: Strong inhibitors or inducers of cytochrome P450, Strong inhibitors of P-glycoprotein, Narrow therapeutic index and sensitive substrates of multidrug and toxin extrusion (MATE)1 and MATE2-K, Narrow therapeutic index and sensitive substrates of P-gp and breast cancer resistance protein
  • * Administration of any of the following within 2 weeks before the first dose of IDE892: Strong inhibitors or inducers of CYP3A4/5, Strong inhibitors of P-gp and/or BCRP, Narrow therapeutic index and sensitive substrates of MATE1 and MATE2-K, Narrow therapeutic index and sensitive substrates of P-gp and BCRP
  • * Use of proton pump inhibitors (PPIs) within 7 days prior to the first dose of IMP or planned use during the study
  • * Use of drugs with known risk for QT prolongation within 2 weeks prior to the first dose of IDE892

  • * Treatment with no more than 3 prior lines, including no more than 2 prior lines of chemotherapy.
  • * If considered standard of care and available, participants whose cancers have proven targetable oncogene alterations must have had disease progression on (unless contraindicated or participant developed intolerance) at least 1 prior line containing appropriate targeted therapy.
  • Urothelial Cancer (Bladder and Upper Urinary Tract), Mesothelioma (Pleural or Peritoneal) and Gastroesophageal Cancers
