• Have any condition or illness that, in the opinion of the Investigator, might compromise patient safety or interfere with the evaluation of the safety of the drug.
• Uncontrolled intercurrent illness including, but not limited to, uncompensated respiratory, cardiac, hepatic, or renal disease, active infection (including human immunodeficiency virus (HIV) and active clinical tuberculosis), or renal transplant; ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, or psychiatric illness/social situations that would limit compliance with study requirements.
• For patients with a history of hepatitis C, active infection as defined by a reactive hepatitis C virus (HCV) antibody test and detectable HCV ribonucleic acid (RNA).
• Active bleeding disorders.

Laborértékek

• Prior treatment with an EGFR ex20ins -targeting drug (eg, including, but not limited to poziotinib, mobocertinib, amivantamab, DZD9008, BDTX-189).
  • Note: enrolment of patients treated previously with EGFR ex20ins-targeting drugs allowed selectively during accelerated titration dose escalation and Module C only.
  • Module A Food Effect PK Assessment Module patients only
• Treatment with any of the following:
  • An EGFR TKI ≤ 8 days or 5 × the terminal phase t1/2, whichever is longer, prior to the first dose of study drug on C1D1.
  • Systemic anticancer treatment (excluding EGFR-TKIs as described above) within 14 days prior to the first dose of study drug on C1D1.
  • Immunotherapy ≤ 28 days prior to the first dose of study drug on C1D1.
  • Radiotherapy \< 28 days and palliative radiation ≤ 14 days prior to the first dose of study drug on C1D1. If irradiated, lesions must have demonstrated clear-cut progression prior to being eligible for evaluation as target lesions.
  • Major surgery (excluding placement of vascular access) ≤ 28 days of the first dose of study drug on C1D1.
• Pregnant or lactating females; females of child-bearing potential (FOCBP) must have a negative serum pregnancy test at within seven days prior to receiving study drug on C1D1. FOCBP and males with partners of child-bearing potential must agree to use adequate birth control (Section 16.3) throughout their participation and for six months following the last dose of study treatment.
• For patients with a history of hepatitis B (HBV), negative PCR test is required. Patients with active hepatitis B (HBV) infection \[as defined by a positive hepatitis B serum antigen (HBsAg) test and detectable HBV deoxyribonucleic acid (DNA)\]. Patients ineligible due to detectable levels of HBV DNA at baseline may be rescreened for enrolment if their HBV DNA levels become undetectable after treatment with antiviral agents, and upon agreement between the Investigator and Sponsor.
