研究概览
简要总结
This is a Phase I open label multi-center study to evaluate the safety, tolerability, pharmacokinetics and preliminary effectiveness of the investigational drug MYTX-011 in patients with locally advanced, recurrent or metastatic NSCLC. MYTX-011 is in a class of medications called antibody drug conjugates (ADCs). MYTX-011 is composed of a pH-dependent anti-cMET antibody and the potent antimicrotubule drug monomethyl auristatin E (MMAE).
详细描述
The study will be conducted in 2 parts. Part 1 will assess the safety and tolerability of MYTX-011 and identify the dose to be studied in Part 2. Part 2 will include subjects with NSCLC with cMET overexpression or MET amplification/exon 14 skipping mutations, populations with a current unmet medical need.

入选标准
- •Histologically or cytologically confirmed locally advanced, recurrent or metastatic NSCLC and have received available standard of care therapy.
- •There is no limit on the number of prior therapies that can have been received.
- •Part 2 Cohorts A-D and F
- •Known to not have an actionable EGFR mutation. Subjects with or without other driver mutations are permitted to enroll.
- •Must have received (or be ineligible for) available standard of care therapy.
- •Must have progressed on at least 1 line of prior systemic therapy in the locally advanced/metastatic setting. Note: multiple TKIs for the same actionable mutation count as 1 line of therapy. Rechallenge of the same therapy regimen within 6 months of discontinuation date of the therapy is not considered a separate line of therapy. Maintenance therapy is not considered a separate line of therapy. Adjuvant and neoadjuvant therapies count as 1 line of therapy if given within 6 months before study entry. The same rules above apply to all inclusion/exclusion criteria regarding prior lines of therapy.
- •Subjects without any actionable gene alteration: must have progressed on (or be considered ineligible for), or be intolerant to, platinum-based chemotherapy and immune checkpoint inhibitor (as monotherapy or in combination with chemotherapy) and have not received more than 2 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Subjects with actionable gene alterations (other than EGFR) for which immune checkpoint inhibitor therapy is not standard of care (e.g., anaplastic lymphoma kinase [ALK] translocation): must have progressed on (or be considered ineligible for), or be intolerant to, anticancer therapy targeting driver gene alterations and platinum-based chemotherapy and have not received more than 3 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Subjects with actionable gene alterations (other than MET exon 14 skipping mutation) for which immune checkpoint inhibitor is standard of care: must have progressed on (or be considered ineligible for), or be intolerant to, anticancer therapy targeting driver gene alteration and platinum-based chemotherapy, and also progressed on (or be considered ineligible for) or be intolerant to immune checkpoint inhibitor(as monotherapy or in combination with platinum-based chemotherapy, and have not received more than 3 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Subjects with MET exon 14 skipping mutation must have progressed on, or be intolerant to, at least one MET TKI if available, and have not received more than 2 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous NSCLC without EGFR mutation.
- •Tumor sample with high cMET expression by IHC confirmed by central laboratory testing.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous NSCLC without EGFR mutation.
- •Tumor sample with intermediate cMET expression by IHC confirmed by central laboratory testing.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous NSCLC without EGFR mutation.
- •Tumor sample with intermediate cMET expression by IHC confirmed by central laboratory testing.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic squamous NSCLC without EGFR mutation.
- •Tumor sample with cMET expression by IHC confirmed by central laboratory testing.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous or adenosquamous NSCLC without EGFR mutation.
- •Tumor sample with low cMET expression on tumor biopsy confirmed centrally by IHC that does not meet inclusion criteria for Cohorts A, B, or B
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for a curative therapy), or metastatic NSCLC with actionable EGFR mutations.
- •Tumor sample with high or intermediate cMET expression by IHC confirmed by central laboratory testing.
- •Must have received an available standard of care therapy and have progressed on at least 1 and no more than 3 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic NSCLC with actionable EGFR mutations.
- •Tumor sample with high or intermediate cMET expression by IHC confirmed by central laboratory testing.
- •Must have received an available standard of care therapy and have progressed on at least 1 line and no more than 3 lines of prior systemic therapy in the locally advanced/metastatic setting.
- •Have histologically or cytologically confirmed locally advanced non-squamous or adenosquamous NSCLC without EGFR mutation.
- •Have ultra-low cMET expression on tumor biopsy confirmed centrally by IHC that does not meet inclusion criteria for Cohorts A,B, B2, or D.

- •Patient has at least one measurable lesion per RECIST 1.1
- •ECOG performance status 0 or 1
