|Accepts Healthy Volunteers:||No|
- ≥18 years of age at the time of signing the informed consent.
- Pathologically confirmed metastatic NSCLC.
Tumor mutation profile determined locally via next generation sequencing (NGS), using tumor tissue (preferably from a progressing lesion) and/or ctDNA in plasma. For Phase 1, it is preferable that samples used for analysis be obtained during or after disease progression on the last EGFR-targeted TKI received. For Phase 2, samples used for analysis must be obtained during or after disease progression on the last EGFR-targeted TKI received.
- All Parts: activating EGFR mutation (Ex19Del or L858R)
- Part 2A: Tumor must additionally harbor an EGFR C797X resistance mutation.
- Part 1A and 2A: At least 1 prior third-generation EGFR-targeted TKI, such as osimertinib
Part 1B: Patients must have experienced progressive disease while on osimertinib, were able to tolerate prior osimertinib 80 mg QD dose, and continuing on osimertinib is deemed to be in the patient's best interests in the opinion of the Investigator.
Patients who have discontinued osimertinib may be eligible, if no more than 6 weeks elapse between the discontinuation of prior osimertinib and resumption of osimertinib on study.
- Part 1C: At least 1 prior EGFR-targeted TKI
- Willing to provide pretreatment tumor sample (either an archival sample or a sample obtained by pretreatment biopsy. For Phase 1, it is preferable that pretreatment tumor sample be obtained from a progressing lesion and during or after disease progression on the last EGFR-targeted TKI received. For Phase 2, pretreatment tumor sample must be obtained during or after disease progression on the last EGFR-targeted TKI treatment received. Patients without appropriate archival tissue available, where biopsy is not considered safe and/or medically feasible, may be discussed with the study medical monitor and approved for enrollment on a case-by-case basis.
- Part 2A: at least 1 measurable target lesion per RECIST 1.1 as assessed by the Investigator

- Any other systemic anticancer therapy within 14 days or 5 half-lives prior to the first dose of study drug, whichever is the shortest, but with a minimum of 7 days in all circumstances. BLU-701 may be started within these washout periods if considered by the Investigator to be safe and within the best interest of the patient, with prior Sponsor approval.
- Radiotherapy to a large field or including a vital organ (including whole brain radiotherapy or stereotactic radiosurgery to brain) within 14 days before the first dose of study drug. Radiotherapy to a focal site of disease that did not include a vital organ (such as a limb) within 7 days before the first dose of study drug.
- Have CNS metastases or spinal cord compression that is associated with progressive neurological symptoms or requires increasing doses of corticosteroids to control the CNS disease. If a patient requires corticosteroids for management of CNS disease, the dose must have been stable for the 2 weeks preceding treatment.

However, upon discussion with the Sponsor, patients who have another concurrent malignancy (not lung cancer) that is clinically stable and does not require tumor-directed treatment may be eligible to participate. Examples include, but are not limited to, completely resected basal cell carcinoma and squamous cell carcinoma of skin; curatively treated prostate cancer, breast cancer; and early gastric cancer cured by endoscopic mucosal resection or endoscopic submucosal dissection.
- Have active, uncontrolled infection (viral, bacterial, or fungal), including tuberculosis, hepatitis B, hepatitis C, AIDS-related illness, or COVID19 infection.
