研究概览
简要总结
This is a Phase 1/2, open-label, first-in-human (FIH) study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of BLU-701 as monotherapy or in combination with either osimertinib or platinum-based chemotherapy in patients with EGFRm NSCLC.
详细描述
The study was planned to include an initial Phase 1 portion to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of BLU-701 as monotherapy (Part 1A; initially in a once daily (QD) regimen with the option to evaluate twice daily (BID) dosing if supported by emerging PK and safety data), as well as additional dose-escalation portions to determine the RP2D of BLU-701 in combination with osimertinib (Part 1B) or in combination with carboplatin and pemetrexed (Part 1C). A Phase 2 part was planned to further evaluate the efficacy and safety of BLU-701 as monotherapy at RP2D (Part 2A). Phase 1 Part 1 A was initiated; however, the study was terminated prior to establishing BLU-701 MTD and/or RP2D.

入选标准
- •≥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.
- •Previously received:
- •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.

排除标准

- •Have NSCLC with mixed cell histology or a tumor with known histologic transformation (NSCLC to SCLC, SCLC to NSCLC, or epithelial to mesenchymal transition).
- •Have received the following anticancer therapy:
- •Any third-generation EGFR TKI (such as osimertinib) within 7 days prior to the planned first dose of study drug. Note: patients in Part 1B do not require a wash-out period for osimertinib.
- •Part 2A: Previous therapy with first- or second-generation EGFR TKI, such as erlotinib, gefitinib, afatinib or dacomitinib.
- •Part 1C: Prior platinum-based chemotherapy for advanced or metastatic disease.
- •Any immunotherapy or other antibody therapy (including EGFR-targeted antibodies or bi-specific antibodies) within 21 days prior to the first dose of study drug.
- •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. Asymptomatic CNS and leptomeningeal disease is allowed and, when measurable, should be captured as target lesions.
- •Have any of the following laboratory abnormalities on last laboratory assessment prior to initiation of study drug (i.e., C1D1 or Screening):
- •Absolute neutrophil count (ANC) <1.0×109/L (for patients in Part 1C: <1.5×109/L)

Exceptions include alopecia and fatigue, and, upon discussion with and approval by the Medical Monitor, other toxicities that are not thought to present a risk to patient safety.
- •Have mean resting QT interval corrected using Fridericia's formula (QTcF) >450 msec, a history of prolonged QT syndrome or Torsades de pointes, or a familial history of prolonged QT syndrome.
- •Have clinically significant, uncontrolled, cardiovascular disease including congestive heart failure Grade III or IV according to the New York Heart Association classification; myocardial infarction or unstable angina within the previous 6 months, uncontrolled hypertension, or clinically significant, uncontrolled arrhythmias, including bradyarrhythmia that may cause QT prolongation (e.g., Type II second degree heart block or third degree heart block).
- •Have history of another primary malignancy (other than completely resected carcinomas in situ) that has been diagnosed or required therapy within 2 years prior to initiation of study 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.
