Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 18-75 years old (including 18 and 75 years old), male or female.
  • Patients with histologically or cytologically confirmed locally advanced or metastatic non-small cell lung cancer (NSCLC) who are not amenable to curative surgery or radiotherapy. (For subjects naive to EGFR-TKI therapy, paraffin-embedded tissue blocks, unstained slides, or fresh tumor tissue samples must be available for EGFR testing.)
  • Patients with a positive EGFR mutation. (For patients with prior third-generation EGFR-TKI therapy, post-progression EGFR mutation test results are recommended.)
  • a) Phase Ⅰ Dose Escalation Stage: EGFR-mutant NSCLC patients who have received at least one prior line of therapy (chemotherapy or targeted therapy are allowed). Patients who have received prior neoadjuvant, adjuvant, and/or radical concurrent/sequential chemoradiotherapy (including chemotherapy, immunotherapy, targeted therapy, etc.) must have documented disease recurrence or progression within <6 months of completing the last regimen. b) Phase Ⅱa Dose Expansion Stage: Cohort 1: NSCLC patients with disease progression on a prior third-generation EGFR-TKI. Cohort 2: EGFR mutant NSCLC patients who are EGFR-TKI-naive.
  • Patients with at least one measurable or evaluable lesion per RECIST 1.1 criteria.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and a life expectancy of at least 12 weeks.
Show all 15Show fewer
  • Adequate organ function must meet the following criteria (with no transfusion of blood, blood products, no administration of hematopoietic growth factors, or no infusion of albumin/blood products within 14 days before laboratory testing):
  • Absolute neutrophil (NE) count ≥ 1.5 × 10^9/L.
  • Platelet (PLT) count ≥ 100 × 10^9/L.
  • Hemoglobin (HGB) ≥ 100 g/L.
  • Serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤ 2.5 × ULN (for patients with liver metastases, TBIL ≤ 3 × ULN and AST/ALT ≤ 5 × ULN are acceptable).
  • Serum creatinine (SCr) ≤ 1.5 × ULN, or creatinine clearance ≥ 50 mL/min. Note: If the investigator deems retesting necessary (with the reason documented), the above laboratory tests may be repeated only once. If the retesting results meet the criteria, they will be considered eligible.
  • Patients with stable intracranial metastatic lesions are eligible. Stable intracranial metastasis is defined as: stable signs and symptoms for at least 2 weeks before enrollment, and discontinuation of corticosteroid treatment for intracranial metastasis for at least 14 days before enrollment. Patients with stable intracranial metastases (including newly identified intracranial metastasis that are treatment-naive) who do not require treatment are eligible. Patients with stable meningeal metastasis are eligible following confirmation by the investigator (Applicable only to dose expansion stage).
  • Women of childbearing potential must have a negative blood pregnancy test and agree to use effective contraception during the study treatment and for 180 days after the last administration. According to the judgment of the investigator, women of childbearing potential in this study are defined as sexually mature women: 1) have not undergone a hysterectomy or bilateral oophorectomy; 2) have not experienced natural menopause last for 12 consecutive months (amenorrhea following cancer treatment does not preclude the possibility of fertility) (i.e., have experienced menstruation with the last 12 consecutive months). Male patients with female partners of childbearing potential must agree to use effective contraception during the study treatment and for 180 days after the last administration.
  • Subjects have been fully informed, have voluntarily sign the informed consent form, and are willing to comply with the study procedures and visit schedule.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GEN-725 tablets + Dositinib mesylate tabletsDrug

    Dose-escalation part (Phase Ⅰ): Subjects will receive once-daily oral administration of GEN-725 tablets in combination with Dositinib mesylate tablets on an empty stomach. GEN-725 will be administered at a dose of 6 mg or 9 mg, and Dositinib will be administered at a dose of 80 mg or 160 mg. Both drugs should be taken concurrently. The treatment will continue until the first occurrence of any of the following: disease progression, unacceptable toxicity, withdrawal of consent, or investigator's determination of no further clinical benefit.

    Dose-expansion part (Phase Ⅱa): Subjects will receive once-daily oral administration of GEN-725 tablets in combination with Dositinib mesylate tablets or Dositinib mesylate tablets alone on an empty stomach. The dose will be selected based on the outcome of dose-escalation phase. The treatment will continue until the first occurrence of any criterion that was specified in the dose-escalation part.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing GEN-725 tablets + Dositinib mesylate tablets in people with Non-Small Cell Lung Cancer, run by Henan Genuine Biotech Co., Ltd. at 5 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jun Zhou (010-88196456, ohjerry@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects with Dose Limiting Toxicity (DLT) in Phase Ⅰ (time frame: From Day 1 to Day 21 of Cycle1 (each cycle is 21 days).). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2026.
