Oral drug that targets two cancer drivers tested in first human study

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Subjects with advanced malignant solid tumors confirmed by histology or cytology. 2. Subjects have previously received standard treatment with failure (including disease progression or toxicity intolerance), or have no available standard treatment plans, or have contraindications to standard treatment. 3. In the dose escalation phase, NTRK or RET gene fusion status is not an eligibility criterion, but subjects harboring NTRK or RET fusion or mutation will be prioritized. However, in the dose expansion phase, subjects must have confirmed NTRK or RET gene fusion/mutation (histologic or cytological genetic testing results are acceptable) . 4. Patients have at least one evaluable lesion according to RECIST version 1.1 evaluation criteria ( Revised RECIST Guidelines (version 1.1) ); 5. Subjects must be 18 years or older (no limitation by sex or maximum age) on the day of signing informed consent . 6. Have an Eastern Cooperative Oncology Group (ECOG) Performance status of 0 to 2. 7. Have a projected life expectancy of at least 12 weeks . 8. Have adequate organ and bone marrow function to meet laboratory examination standards. 9. Fertile male subjects and childbearing potential female subjects agree to use highly effective contraception from the time of signing informed consent until 6 months after the final dose of investigational product. Childbearing potential female subjects include premenopausal women and women within 2 years after menopause; Pregnancy testing results for childbearing potential female subjects within ≤ 7 days before the first administration must be negative. 10. Capable of understanding the written informed consent document; willingly provides valid, signed written informed consent; willing and able to comply with the schedule, requirements and restrictions of the study. Exclusion criteria: 1. Known hypersensitivity to ND-003 or any of its constituents. 2. Previous exposure to ND-003. 3. Subjects participated or are currently participating in clinical trials of other drugs or medical devices within 4 weeks prior to the first administration. 4. Subjects underwent major surgery within 4 weeks before the first administration or had a surgical plan during the study period. 5. Received systemic anti-tumor drug therapy such as chemotherapy, macromolecular targeted therapy, endocrine therapy within 3 weeks before the first administration (subjects have previously used nitrosourea or mitomycin C with a washout period of at least 6 weeks; subjects have previously used oral fluorouracil drugs or small molecule targeted drugs with a washout period of at least 2 weeks or 5 half-lives, whichever is the longer.) or radiation therapy, or immunotherapy within 4 weeks before administration. 6. Use traditional Chinese patent medicines with anti-tumor effect within 2 weeks before the first administration. 7. Receipt of live vaccine within 4 weeks prior to study drug administration or plan to receive them during the study period, including but not limited to: measles, mumps, rubella, chickenpox, yellow fever, rabies, Bacillus calmette-guerin (BCG) and typhoid vaccines. 8. Subjects who used known concomitant drugs that can prolong the QT interval and/or CYP2C8, CYP3A strong inhibitors and/or inducers within 7 days before the first administration, as well as those who need to continue using the aforementioned drugs during the study period. 9. Subjects who have suffered from another type of malignant tumor within the past 5 years, excluding those who have received curative treatment for cervical cancer in situ, non melanoma skin cancer, localized prostate cancer, ductal cancer in situ, and other extremely low-risk malignant tumors. 10. Loss or donation of blood \> 500 mL (within 3 months before the first administration). 11. Donation of bone marrow or peripheral stem cells (within 3 months before the first administration). 12. Uncontrolled or symptomatic central nervous system (CNS) metastasis including symptomatic brain metastasis or meningeal metastasis or spinal cord compression; but the following patients are allowed to be included: a. subjects with treated brain metastasis (such as surgery or radiation therapy), there was no progress in imaging and/or no neurological symptoms or signs appeared after treatment at least 4 weeks before the first administration, there was no evidence of new brain metastasis or increased metastasis, and systemic hormone therapy (dosage\>10 mg/day of prednisone or other effective hormones) was stopped at least 4 weeks before the first administration; b. Untreated and asymptomatic subjects with brain metastases do not require corticosteroids, and the length of brain metastases are ≤ 1.5 cm. 13. Suffering from uncontrollable diseases, including but not limited to: 1）Existence of persistent or active infections (including bacteria, fungi, viruses, etc.) that require antibiotic, antifungal, or antiviral treatment; 2）Acute coronary syndrome, congestive heart failure (New York Heart Association Cardiac Function Classification ≥ Level II), left ventricular ejection fraction (LVEF)\<50%, cerebrovascular accident, transient ischemic attack, stroke, deep vein thrombosis, pulmonary embolism, aneurysm, arterial dissection, or other level 3 or above cardiovascular and cerebrovascular events occurred within 6 months before the first administration; 3）Investigator considers that arrhythmias (such as bradycardia) with clinical significant or conduction abnormalities, congenital long QT interval syndrome or Fridericia's corrected QTc (corrected QT interval) are unmeasurable or QTcF\>450 msec; 4）Uncontrolled hypertension (systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure ≥ 100 mmHg) or hypotension (systolic blood pressure less than 80 mmHg and/or diastolic blood pressure less than 50 mmHg); 5）Uncontrolled hyperglycemia; 6）Active peptic ulcer disease or gastritis, active hemorrhagic disease; 7）Mental illness/social conditions that affect patients' compliance with clinical trials and their ability to sign written informed consent forms. 14.Have family history of long QT syndrome or unexplained sudden death in first degree relatives under the age of 40. 15.Unable to swallow medication orally, have gastrointestinal abnormalities with clinical significant (such as after gastrointestinal resection, gastrointestinal anastomosis, chronic diarrhea, and intestinal obstruction), or have significant impact on gastrointestinal absorption as determined by the investigator 16.Individuals with difficulty in venous blood collection (such as fainting or fainting history due to syringe) 17.History of drug or alcohol abuse . 18.Human immunodeficiency virus (HIV) antibodies positive or active syphilis or active pulmonary tuberculosis (determined by the investigator based on the tuberculin test or γ- Interferon release test \[T-SPOT test\] results, imaging examination results and comprehensive judgment of clinical symptoms) or hepatitis C virus antibody positive and hepatitis C virus (HCV) RNA positive, or active hepatitis B patients (hepatitis B surface antigen positive and HBV (Hepatitis B virus honeybee venom) DNA ≥ the upper limit of normal value). 19.Failure to recover from any AE related to previous surgical procedures and previous cancer treatment (CTCAE 5.0 rating to ≤ 1), except for the following situations: a. hair loss; b. Level 1 toxicity without clinical significance, such as lymphopenia. 20.Pregnant or lactating women, or planning to conceive during the study period. 21.Investigator considers that the subjects may have other situations that may affect compliance or may not be suitable to participate in this trial.
