Objectives

Part 1: MYTX-011 Dose Escalation main purpose ‧ Evaluating the safety and tolerability of MYTX-011 ‧ Determination of RP2D and/or MTD of MYTX-011 secondary purpose ‧ Describe the PK properties of MYTX-011, including total ADC, total antibodies, and free MMAE ‧ Determining the optimal biological dose of MYTX-011 in Cohort A: based on safety, PK and preliminary anti-tumor activity ‧ To assess the incidence and persistence of ADA in response to MYTX-011 ‧ Determination of preliminary anti-tumor activity of MYTX-011 exploratory purpose ‧ Measure the extent of cMET expression in tumor tissue and whether there are changes in MET ‧ Evaluate biomarkers and predictors (e.g., molecular, genetic, protein) of response and resistance to MYTX-011 in tumors and blood Part 2: MYTX-011 Dose Expansion (Cohorts A to E) main purpose ‧ Cohort A: Advanced non-squamous NSCLC with high cMET expression and no actionable EGFR mutation ‧ Cohort B: Advanced non-squamous NSCLC with intermediate cMET manifestations and no actionable EGFR mutation ‧ Cohort C: Advanced squamous cell NSCLC with cMET overexpression and non-functioning EGFR mutations ‧ Cohort D: Advanced squamous or non-squamous NSCLC with MET amplification or exon 14 skipping mutations and no contributing EGFR mutation ‧ Cohort E: Advanced squamous or non-squamous NSCLC with cMET manifestations, ineffective EGFR mutations, and prior cMET ADC or antibody therapy secondary purpose ‧ Evaluating the safety and tolerability of MYTX-011 ‧ Describe the PK properties of MYTX-011, including total ADC, total antibodies, and free MMAE ‧Describe the anti-tumor activity of MYTX-011 ‧ Exploring the optimal biological dose of MYTX-011 in Cohort A ‧ To assess the incidence and persistence of ADA in response to MYTX-011 exploratory purpose ‧Measuring the extent of cMET expression in tumor tissue ‧ Evaluate biomarkers and predictors (e.g., molecular, genetic, protein) of response and resistance to MYTX-011 in tumors and blood

Test Drug

MYTX-011

Active Ingredient

MYTX-011

Dosage Form

Vial for Injection

Dosage

100mg/10mL

Endpoints

‧ Incidence and severity of TEAEs, AEs, and clinically significant changes in vital signs, ECG, and laboratory parameters compared to the baseline period
‧ RP2D will be selected as the biologically active dose at or below the MTD (or if the MTD is not determined during the trial, the highest dose tested)
‧ MTD will be determined by DLT during Cycle 1. The observation period for DLT is Cycle 1.
‧ ORR (confirmed CR+PR) of each expansion group based on RECIST version 1.1

Inclution Criteria

Inclusion Criteria:

Part 1:

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:

Cohort A:

Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous NSCLC.
Tumor sample with high cMET expression by IHC confirmed by central laboratory testing.
Cohort B:

Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic non-squamous NSCLC.
Tumor sample with intermediate cMET expression by IHC confirmed by central laboratory testing.
Cohort C:

Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic squamous NSCLC.
Tumor sample with cMET overexpression by IHC confirmed by central laboratory testing.
Cohort D:

Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic NSCLC.
Tumor sample that does not meet cMET IHC entry criteria for Cohorts A-C
Known MET amplification or exon 14 skipping mutations respectively. Patients with MET exon 14 skipping mutations must have received MET TKI therapy if available and considered standard of care.
Cohort E:

Have histologically or cytologically confirmed locally advanced, recurrent (and not a candidate for curative therapy), or metastatic NSCLC.
Evidence of cMET expression by IHC as documented in medical records.
No more than 3 prior lines of systemic therapy including prior cMET targeted ADC or antibody.
Part 2 Cohorts A-D

- No more than two prior lines of therapy in the locally advanced/metastatic setting.

Part 2 Cohorts A-E:

Known to not have an actionable EGFR mutation. Patients with or without other driver mutations are permitted to enroll.
Patients without any actionable gene alteration: must have progressed on (or be considered ineligible for) standard of care therapy
Patients with actionable gene alterations (other than EGFR) must have progressed on (or be considered ineligible for) or be intolerant to anti-cancer therapy targeting driver gene alterations and available standard of care therapy
All patients (Part 1 and Part 2)

Patient has at least one measurable lesion per RECIST 1.1
ECOG performance status 0 or 1
For women of childbearing potential and men with partners of childbearing potential, agreement to use a highly effective method of birth control for the duration of the study treatment and for at least 6 months after the last dose of study drug.
Able to provide informed consent, and willing and able to comply with study protocol requirements

Exclusion Criteria

Exclusion Criteria:

-Radiation to the lung within 2 months prior to screening.
-Major surgery within 28 days of first dose of study drug administration.
-Untreated, uncontrolled CNS metastases.

-Clinically significant systemic illness that could pose undue risk to the subject or confound the ability to interpret study results.
-Active infection requiring IV antibiotics, antivirals, or antifungal medication
-Neuropathy > Grade 1
-History of cirrhosis, hepatic fibrosis, esophageal or gastric varices, or other clinically significant liver disease.
-Active or chronic corneal disorder
