Study of Turning Point Therapeutics LM-302 in Patients With Advance Solid Tumors

Exclusion Criteria

• •Exposure to any IMP, or participate in any other clinical trial within 21 days prior to 1st dosing of LM-302;
• •Subjects with anti-tumor treatment within 21 days prior to 1st dosing of LM-302, including radiotherapy, chemotherapy, biotherapy, endocrine therapy and immunotherapy, etc. Following treatments have different time limits:
• •Local small-scale palliative radiotherapy (bone metastasis radiotherapy to control pain) within 14 days prior to 1st dosing;
• •Oral anti-tumor therapy, including fluorouracil antitumor drugs and small molecular targeted drugs, etc. within 14 days or 5 half-life of the drug (whichever is shorter) prior to 1st dosing;
• •Traditional Chinese medicine with anti-tumor indication within 14 days prior to 1st dosing.
• •Nitrosourea or Mitomycin C within 42 days prior to 1st dosing.
• •Any adverse event from prior anti-tumor therapy has not yet recovered to ≤ grade 1 of CTCAE v5.0 (Except for toxicities without safety risk judged by the investigator, such as alopecia, and other ≤ grade 2 long term toxicities);
• •Pre-existing peripheral sensory or motor neuropathy ≥ Grade 2;
• •Subjects with uncontrolled tumor-related pain. Subjects requiring analgesic treatment must be on a stable regimen before participating in the study. Symptomatic lesions amenable by palliative radiotherapy (e.g., bone metastases or metastases causing nerve damage) should be treated prior to enrolment. For the asymptomatic metastatic lesions whose further growth would likely cause functional defects or intractable pain, if appropriate, local treatment should be considered before enrolment;
• •Subjects with known central nervous system (CNS) or meningeal metastasis;
• •Subjects who have uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures;
• •Subjects who are allergic or hypersensitive to LM-302 (The excipients are L-Glutamic acid, L-Arginine, Trehalose dihydrate and polysorbate 80 (for injection)) or similar products;
• •Subjects who have received the treatment targeting to CLDN18.2 or Monomethyl Auristatin E(MMAE) based Antibody-Drug Conjugates (ADCs):
• •Administrate strong inhibitors/strong inducers of CYP3A4 within 14 days prior to 1st dosing of LM-302;
• •Subjects with known active keratitis or corneal ulcerations. Subjects with superficial punctate keratitis are allowed if the disorder is being adequately treated in the opinion of the investigator.
• •Use of any live vaccines (e.g., against infectious diseases such as influenza, varicella, COVID-19, etc.) within 28 days prior to 1st dosing of LM-302;
• •Subjects with the history of interstitial lung disease or drug-induced interstitial lung disease/pneumonitis;
• •Subjects who are taking therapeutic doses of anticoagulants such as heparin or vitamin K antagonists (except for preventive treatment at a stable dose);
• •Subjects with gastric outlet obstruction, persistent recurrent vomiting or uncontrolled/severe gastrointestinal hemorrhage, or ulcer within 28 days prior to 1st dosing of LM-302;
• •Subjects who received major surgery or interventional treatment within 28 days prior to 1st dosing of LM-302 (excluding tumor biopsy, puncture, etc.);
• •Subjects who have other active malignancies which are likely to require the treatment;
• •Subjects who have severe cardiovascular disease, including but not limited to:
• •Severe cardiac rhythm or conduction abnormalities, such as ventricular arrhythmia requiring clinical intervention, and II-III degree atrioventricular block, etc.;
• •Thromboembolic events requiring therapeutic anticoagulation, or equipped with venous filters;
• •Cardiac insufficiency of grade III\~IV according to the New York Heart Association (NYHA) standards;
• •Acute coronary syndrome, congestive heart failure, aortic dissection, stroke, or other cardiovascular and cerebrovascular events of grade 3 or above occurred within 6 months prior to 1st dosing of LM-302;
• •Clinically uncontrollable hypertension;
• •Subjects who have uncontrolled or severe illness, including but not limited to ongoing or active infection (e.g., active Corona Virus Disease 2019（COVID-19）/Severe Acute Respiratory Syndromes(SARS)-COVID-2 infection, etc.) requiring antibiotics and/or other therapeutic administration, while SARS-COVID-2 testing is not mandatory for study entry, and the testing should follow local clinical practice guidelines/standards.
• •Subjects who have a history of immunodeficiency disease, including other acquired or congenital immunodeficiency diseases, or organ transplantation, or allogeneic bone marrow transplantation, or autologous hematopoietic stem cell transplantation;
• •HIV infection, active Hepatitis B Virus(HBV) and Hepatitis C Virus(HCV)infection, with the exception:
• •Subjects with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody \[anti-hepatitis B core(HBc)\] and absence of HBsAg), as well as with normal liver function are eligible. Otherwise, if HBV infection was indicated, those with HBV DNA \< 500 IU/ML (or equivalent level) and normal liver function, combined with clinical manifestations, judged by the investigator to exclude active infection can be enrolled;
• •Subjects with positive HCV antibody but negative hepatitis C virus RNA test results and normal liver function are eligible.
• •Child-bearing potential female who have positive results in pregnancy test or are lactating;
• •Subjects who have psychiatric illness or disorders that may preclude study compliance;
