study of tpx-0022 in patients with advanced nsclc, gastric cancer or solid tumors harboring genetic alterations in met

Conditions: Advanced Solid Tumor; Metastatic Solid Tumors; MET Gene Alterations

Summary: a phase 1/2, first-in-human, open-label study of the safety, tolerability, pk, and efficacy of the novel met/csf1r/src inhibitor tpx-0022 in adult subjects with advanced or metastatic nsclc, gastric cancer, or solid tumors harboring genetic alterations in met. (shield-i)

dose escalation: to evaluate the overall safety profile of tpx-0022, single and multiple dose pk profiles and preliminary efficacy in adults subjects with advanced solid tumors harboring genetic alterations in met. dose expansion: to evaluate the preliminary efficacy and overall safety profile of tpx-0022 at the rp2d in defined cohorts of adult subjects in nsclc, gastric cancer and advanced solid tumors harboring genetic alterations in met.

Eligibility criteria:
inclusion criteria: 1. age ≥ 18 (or age ≥ 20 as required by local regulation). 2. histological or cytological confirmation of advanced/metastatic met exon 14 skipping mutation (metδex14) nsclc, met amplified nsclc, or met amplified gastric cancers as determined by fish, qpcr or ngs by local liquid biopsy or tissue, solid tumors with met fusions or oncogenic met mutations or met amplified other than gi/nsclc. 3. ecog performance status ≤ 1. 4. existence of measurable or evaluable disease (according to response evaluation criteria in solid tumors \[recist v1.1\] criteria). 5. subjects with asymptomatic primary cns tumors or brain metastases are eligible for the study if they meet protocol specified criteria. 6. adequate organ function. 7. life expectancy ≥ 12 weeks. exclusion criteria: 1. locally advanced solid tumor that is a candidate for curative treatment through radical surgery and/or radiotherapy, or chemotherapy. 2. presence or history of any other primary malignancy within the past 3 years other than a history of adequately treated basal or squamous cell carcinoma of the skin, or any adequately treated in situ carcinoma. 3. major surgery within four weeks of the start of therapy. 4. additional exclusion criteria for subjects with nsclc with met alterations: known oncogene mutations (eg, alk, ros1, kras, egfr, etc.) for which there are approved therapies. 5. additional exclusion criteria for subjects with hcc with met alterations: liver dysfunction greater than child-pugh class a. 6. clinically significant cardiovascular disease (either active or within six months before enrollment): myocardial infarction, unstable angina, coronary/peripheral artery bypass graft, symptomatic congestive heart failure (new york heart association classification class ≥ ii), cerebrovascular accident or transient ischemic attack, symptomatic bradycardia, requirement for anti-arrhythmic medication. ongoing cardiac dysrhythmias of ctcae version 5.0 grade ≥ 2. 7. any of the following cardiac criteria: * mean resting corrected qt interval (ecg interval measured from the onset of the qrs complex to the end of the t wave) for heart rate (qtc) \> 470 msec obtained from three ecgs, using the screening clinic ecg machine-derived qtc value * any clinically important abnormalities in rhythm, conduction, or morphology of resting ecg (e.g., complete left bundle branch block, third degree heart block, second degree heart block, pr interval \> 250 msec) * any factors that increase the risk of qtc prolongation or risk of arrhythmic events such as heart failure, congenital long qt syndrome, family history of long qt syndrome, or any concomitant medication known to prolong the qt interval 8. known clinically significant active infections not controlled with systemic treatment (bacterial, fungal, viral including hiv positivity). 9. peripheral neuropathy ≥ grade 2.
