Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with advanced lung cancer (NSCLC) or pancreatic cancer whose tumour has an MTAP deficiency (MTAP deletion).

Age
18 years or older
Sex
All sexes
Disease stage
Advanced or metastatic non-small cell lung cancer or pancreatic ductal adenocarcinoma, confirmed by tissue or cell testing, with at least one measurable lesion (RECIST version 1.1).
Earlier treatment
Prior treatment must meet the protocol's requirements for each cohort. People who had treatment aimed at the MAT2A or PRMT5 pathway cannot join.
Biomarker or test result
Tumour with MTAP deficiency found by a validated test.

Main reasons for not taking part

  • Earlier treatment targeting the MAT2A or PRMT5 pathway
  • Known driver gene changes excluded for certain lung cancer cohorts (for example EGFR, ALK, ROS1, KRAS G12C)
  • Significant stomach or bowel disorders that may affect drug absorption
  • Clinically significant heart disease
  • Known HIV infection, active hepatitis B or active hepatitis C

Show all 18 criteriaShow less

Who can take part

  • Adult participants aged 18 years or older
  • ECOG performance status of 0 to 1
  • Life expectancy of at least 3 months
  • Histologically or cytologically confirmed advanced malignant tumor with MTAP deficiency identified by a validated assay
  • At least one measurable lesion according to RECIST version 1.1
  • For NSCLC cohorts: advanced or metastatic NSCLC meeting protocol-specified disease characteristics and prior treatment requirements
  • For PDAC cohorts: advanced or metastatic PDAC meeting protocol-specified disease characteristics and prior treatment requirements
  • Adequate bone marrow, hepatic, renal, and coagulation function
  • Willingness to provide tumor tissue and/or undergo protocol-required biomarker testing, if applicable

Who cannot take part

  • Prior exposure to agents targeting the MAT2A or PRMT5 pathway
  • Prior antitumor therapy or unresolved toxicities not meeting protocol-defined washout/recovery requirements
  • Use of prohibited concomitant medications, including strong inhibitors or inducers of CYP3A4, P-gp, BCRP, or other protocol-specified transporters/enzymes within the required washout period
  • Significant gastrointestinal disorders that may affect drug absorption
  • Uncontrolled metabolic disease, uncontrolled hypertension, or active infection
  • Known HIV infection, active hepatitis B with significant viral replication, or active hepatitis C infection
  • Other serious medical or psychiatric conditions that, in the investigator's judgment, would make study participation inappropriate
  • Known actionable driver alterations or prior therapies excluded by the protocol for specific NSCLC cohorts (for example EGFR, ALK, ROS1, BRAF, NTRK, MET, RET, KRAS G12C, HER2, as applicable)
  • Clinically significant cardiovascular disease, including clinically relevant QTc prolongation, reduced left ventricular ejection fraction, or severe heart failure

About the trial

What the trial wants to find out

This is a Phase Ib, open-label, multicenter study of HSK41959 tablets in combination with standard therapy in patients with MTAP-deficient advanced solid tumors. The study consists of dose-escalation and dose-expansion parts and is intended to evaluate the safety, tolerability, dose-limiting toxicity, maximum tolerated dose, pharmacokinetics, pharmacodynamics, and preliminary efficacy of HSK41959 tablets when used together with standard therapy.

The 4 groups in the trial

  • Dose-Escalation ArmTreatment being tested

    Treatment: HSK41959, Sintilimab, Pemetrexed + Cisplatin /Carboplatin, Paclitaxel + Carboplatin, and Nab-paclitaxel + Carboplatin

  • Dose-Expansion:First-line NSCLC cohortTreatment being tested

    Treatment: HSK41959, Sintilimab, Pemetrexed + Cisplatin /Carboplatin, Paclitaxel + Carboplatin, and Nab-paclitaxel + Carboplatin

  • Dose-Expansion Second-line NSCLC cohortTreatment being tested

    Treatment: HSK41959 and Docetaxel

  • Dose-Expansion First-line PDAC cohortTreatment being tested

    Treatment: HSK41959 and Nab-paclitaxel + Gemcitabine

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
