New cancer drug AL58805 enters first human tests

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

Inclusion Criteria: Subjects must meet all the following criteria to be eligible: 1. Patients with histologically or cytologically confirmed advanced tumors (including but not limited to lymphoma, colorectal cancer, breast cancer, pancreatic cancer, lung cancer, head and neck cancer, bladder cancer, cholangiocarcinoma) who lack effective standard treatment options or have failed conventional standard treatments (due to disease progression or intolerable toxicity). 2. Previous treatment with cytotoxic chemotherapy, with at least 4 weeks between the end of chemotherapy and enrollment, and recovery from previous chemotherapy toxicities to ≤ Grade 1 (except alopecia). 3. Must have measurable lesions according to RECIST 1.1 criteria. 4. Major organ function: Absolute neutrophil count (ANC) ≥1.5 × 10\^9/L (1500/mm3), platelets ≥75 × 10\^9/L, hemoglobin ≥9g/dL. Serum total bilirubin ≤2 × upper limit of normal (ULN). Serum creatinine ≤1.5 × ULN or creatinine clearance ≥50 mL/min. For patients without liver metastases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 × ULN; for patients with liver metastases, ALT and AST ≤5 × ULN. Left ventricular ejection fraction (LVEF) ≥ lower limit of normal. 5. Age ≥18 years; ECOG performance status (PS) 0 or 1. 6. Expected survival time of at least 12 weeks. 7. No malabsorption or other gastrointestinal diseases affecting drug absorption. 8. For women of childbearing potential: Negative pregnancy test before treatment and use of medically approved contraception during treatment and for 3 months after treatment ends. Must be non-lactating. 9. For male subjects: Surgical sterilization or use of medically approved contraception during treatment and for 3 months after treatment ends. Ability to understand and sign informed consent. Exclusion Criteria: Subjects meeting any of the following criteria will be excluded: 1. Known allergy to the investigational drug or drugs with similar chemical structures. 2. Use of unapproved drugs or other investigational drugs within 30 days before enrollment. 3. Status of the organ systems: Current symptomatic brain metastases or leptomeningeal metastases, or central nervous system (CNS) metastases with uncontrolled symptoms within 8 weeks of first dose. Uncontrolled hypertension requiring multiple medications (Grade 2 or higher). Acute myocardial infarction within 6 months. Current arrhythmias (e.g., long QT syndrome, Bazett's corrected QTc ≥480 ms). NYHA Class III or IV heart failure. Poorly controlled diabetes. Any unstable systemic disease (including active infection, angina, hepatic, renal, or metabolic diseases). Presence of ascites or pleural effusion (CTCAE 5.0 ≥ Grade 2). Persistent diarrhea (average watery stools ≥1 per day). History of definite neurological or psychiatric disorders (e.g., epilepsy, dementia, mood disorders). 4. The functional level of each organ： Urine protein ≥++ and 24-hour urine protein \>1.0 g. Patients treated with anticoagulants or vitamin K antagonists, such as warfarin, heparin, or their analogs, should have an international normalized ratio (INR) of prothrombin time ≤1.5. In this case, low-dose warfarin (1mg, orally, once daily) or low-dose aspirin (daily dose not exceeding 100mg) can be used for prophylactic purposes. All other conditions are considered exclusion criteria. Patients with active/venous thrombosis events within 6 months, such as cerebrovascular accidents (including transient ischemic attacks), deep vein thrombosis and pulmonary embolism. 5. Previous treatment with the investigational drug. 6. Patients exhibiting hepatitis B surface antigen (HBsAg) positivity with HBV DNA concentrations ≥10⁴ copies/mL (equivalent to 2000 IU/mL) must initiate antiviral therapy prior to study consideration. Eligibility for enrollment is contingent upon achieving sustained HBV-DNA suppression below these threshold values. Antiviral therapy will be maintained throughout the study period with concurrent monitoring of hepatic function parameters and quantitative HBV DNA levels. The exclusion criteria further encompass individuals with detectable HCV antibodies or HCV RNA, HIV seropositivity, congenital/acquired immunodeficiencies, or prior organ transplantation history. 7. Concurrent other anti-tumor treatments. Other conditions deemed unsuitable by the investigator.
