FHND9041 Versus Afatinib for Non-small Cell Lung Cancer

Phase 3

• Conditions: Non Small Cell Lung Cancer
• Interventions: Drug: FHND9041; Drug: Afatinib

• Registration Number: NCT06759857
• Lead Sponsor: Jiangsu Chia Tai Fenghai Pharmaceutical Co., Ltd.

Brief Summary

The goal of this clinical trial is to evaluate the effectiveness and safety of FHND9041 compared to afatinib as first-line treatments for epidermal growth factor receptor mutation-positive (EGFRm+) locally advanced or metastatic non-small cell lung cancer (NSCLC). The main questions it aims to answer are:

* Does FHND9041 improve progression-free survival (PFS) compared to afatinib?

* Are there differences in safety profiles between FHND9041 and afatinib?

Researchers will compare FHND9041 (80 mg, orally, once daily) with afatinib (40 mg, orally, once daily) in a randomized, open-label, parallel-controlled, multicenter Phase III trial.

Participants who meet the inclusion criteria, including having EGFR mutations (L858R and/or Exon 19 deletion) and no prior treatment, will be randomly assigned in a 1:1 ratio to either the FHND9041 group or the afatinib group. Treatment will continue until disease progression, intolerable drug-related toxicity, or other pre-specified treatment discontinuation criteria are met.

Study Procedures:

Participants will:

* Be screened for eligibility and randomly assigned to one of two groups.

* Receive study drugs per their assigned group.

* Undergo regular tumor assessments by Response Evaluation Criteria in Solid Tumors, version 1.1( RECIST 1.1) every six weeks during the first 18 cycles, then every nine weeks until disease progression. For intracranial efficacy, Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM ) criteria will be applied.

* Participate in pharmacokinetic studies (FHND9041 group only) with blood samples collected pre-dose at specified cycles and on the day of discontinuation.

After disease progression, participants will be followed for survival every three months.

Inclusion Criteria

• Participants aged ≥ 18 years, with no gender restrictions.
• Histologically or cytologically confirmed diagnosis of locally advanced or metastatic non-small cell lung cancer (NSCLC), including patients with recurrent disease following prior surgical treatment or newly diagnosed Stage IIIb, IIIc, or IV NSCLC (staging based on the 8th edition of the AJCC guidelines).
• No prior systemic anti-tumor therapy (e.g., standard chemotherapy, targeted therapy, biological therapy, or immunotherapy). Patients who have received adjuvant or neoadjuvant therapy (chemotherapy, radiotherapy, or other treatments) are eligible if disease progression occurred at least 6 months after completing the prior treatment.
• Presence of a confirmed EGFR-positive gene mutation sensitive to EGFR-TKI treatment, including exon 19 deletion or L858R mutation.
• At least one measurable tumor lesion at baseline that meets the following criteria:

No prior radiotherapy or biopsy during the screening period (if the subject has only one measurable lesion, fine-needle aspiration cytology to confirm genetic status is permitted; however, baseline imaging must be performed at least 7 days after the biopsy).

Lesion can be accurately measured with a longest diameter ≥ 10 mm (or a short axis ≥ 15 mm for lymph nodes).

Lesion can be assessed using CT or MRI, with the same imaging modality used consistently for subsequent evaluations.

• An Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1.
• A life expectancy of ≥ 3 months.
• Female participants of childbearing potential must have a negative serum pregnancy test prior to enrollment. Male and female participants with reproductive potential must agree to maintain abstinence or use effective contraception during the study and for at least 3 months following the last dose of the investigational drug.
• Participants must demonstrate the ability to understand the study objectives and procedures, comply with protocol requirements, cooperate with study-related visits, and provide written informed consent, indicating their voluntary participation.
