New drug AWT020 takes on advanced solid tumors

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

Inclusion Criteria: 1. Both male and female subjects who are at least 18 years old at the time of signing the consent form; 2. Inclusion of patients with advanced malignancies confirmed histologically or cytologically and meeting the following requirements: * Single-agent dose escalation and expansion phase to include patients with advanced malignant tumors who have failed or are intolerant of standard treatment, or have no standard treatment options; * Therapeutic effect expansion stage of single drug: 1. NSCLC: histologically or cytologically confirmed, unresectable locally advanced, relapsed, or distant metastatic NSCLC that has progressed after prior treatment with PD-(L)1 antibody and platinum-containing chemotherapy (except after the last dose \> Progression of adjuvant and neoadjuvant therapy within 6 months). Subjects with EGFR or ALK mutations will need to progress with prior treatment with appropriate kinase inhibitors. 2. Melanoma: histologically unresectable stage III or IV melanoma that has progressed after prior chemotherapy and treatment with PD-(L)1 inhibitors (except after the last dose \> Adjuvant and neoadjuvant therapy that progresses within 6 months); Mucosal melanoma does not require prior PD-(L)1 inhibitor therapy. 3. CRC: colorectal adenocarcinoma or rectal adenocarcinoma with histologically confirmed PD-L1 composite positive score \[CPS\] ≥1, failure or intolerance of standard treatment, or no standard treatment options. PD-L1 expression levels in tumor tissues are based on the results of the central laboratory tests designated by the sponsor (the inclusion criteria for PD-L1 expression levels can also be adjusted according to previous data during the study). 4. RCC: Histologically confirmed metastatic or unresectable clear cell type of RCC with disease progression after previous treatment with targeted anti-angiogenesis therapy and PD-(L)1 inhibitors. 5. Other advanced malignancies: patients with advanced malignancies who have failed or been intolerant to standard treatment or have no standard treatment options. * Combination phase: 1. NSCLC: histologically or cytologically confirmed, unresectable locally advanced, relapsed, or distant metastatic NSCLC that has not progressed after prior treatment with PD-(L)1 antibody and platinum-containing chemotherapy (except after the last dose \> Progression of adjuvant and neoadjuvant therapy within 6 months). Subjects carrying EGFR or ALK mutations were allowed to progress on kinase inhibitor therapy with a previous ≤1 line. 2. CRC: Histologically confirmed PD-L1 CPS≥1 colorectal adenocarcinoma or rectal adenocarcinoma without prior systemic therapy (except after the last dose of medication \> Adjuvant therapy that progresses within 6 months); In patients with MSI-H/dMMR, previous treatment with PD-(L)1 inhibitors is permitted. PD-L1 expression levels in tumor tissues are based on the results of the central laboratory tests designated by the sponsor (the inclusion criteria for PD-L1 expression levels can also be adjusted according to previous data during the study). 3. RCC: Histologically confirmed metastatic or unresectable clear cell RCC with disease progression after previous treatment with anti-angiogenesis targeted therapy and PD-(L)1 inhibitors. 4. Melanoma: histologically unresectable stage III or IV melanoma that has progressed after prior chemotherapy and treatment with PD-(L)1 inhibitors (except after the last dose \> Adjuvant therapy that progresses within 6 months). 5. HCC: Histologically/cytologically confirmed or cirrhotic patients meet the clinical diagnostic criteria for HCC in AASLD, are identified as having stage B (intermediate) or stage C (advanced) BCLC HCC and are not candidates for radical surgery and/or local therapy, and have previously received PD-(L)1 inhibitors and anti-angiogenic targeted therapy progression. 6. Other advanced malignancies: patients with advanced malignancies who have failed or been intolerant to standard treatment, or have no standard treatment options. 3. ECOG score is 0 or 1; 4. Expected survival ≥12 weeks; 5. Have at least one measurable lesion according to RECIST 1.1 evaluation criteria; 6. Good organ function; 7. Fertile female or male subjects must agree to be childfree during the study period until 6 months after the end of the last dose and voluntarily take highly effective contraception with their partner; The serum pregnancy test for WOCBP must be negative within 7 days prior to the first dose and must be non-lactation (specific contraceptive methods and WOCBP definitions are set out in section 10.3); 8. Patients participate voluntarily, give full informed consent, sign written informed consent, and have good compliance. Exclusion Criteria: 1. Received the following drugs or treatments before the first dose: 1. received chemotherapy, immunotherapy and other anti-tumor therapy or other investigational drugs within 21 days before the first dose, or received oral fluorouracil, small molecule targeted drugs or Chinese medicines with anti-tumor indications within 14 days before the first dose; 2. Major surgery or radiotherapy within 28 days before the first dose (palliative radiotherapy for local bone/brain lesions allowed within 14 days before the first dose), coarse needle puncture biopsy or other minor surgery within 7 days before the start of study therapy, excluding placement of vascular infusion devices; 3. In combination therapy, patients who have been systematically treated with corticosteroids (\> 10 mg prednisone per day or equivalent) or other immunosuppressants for more than 1 week within 2 weeks prior to initial administration are allowed to be treated with inhaled or topical steroids or ≤10 mg/ day systemic prednisone and equivalent doses of similar drugs; 2. There is active central nervous system metastasis. If the patient has received radiotherapy or surgery in the past, imaging examination within 4 weeks before the first medication indicates stable brain metastases without aggravation or new neurological symptoms, hormone therapy has been discontinued 2 weeks before the first medication, and screening is allowed; For meningeal and brainstem metastases, screening is not allowed regardless of treatment. 3. Immune-related adverse events that led to permanent discontinuation occurred during previous immunosuppressive therapy (such as anti-PD -(L)1, CTLA-4, LAG-3 inhibitors, etc.); 4. There are pleural effusion, abdominal effusion or pericardial effusion with clinical symptoms that require repeated treatment (puncture or drainage, etc.); 5. There is a history of interstitial lung disease or a history of non-infectious pneumonia treated with corticosteroids, or imaging evidence of active pneumonia during the screening period; 6.

Severe infection occurred within 28 days prior to administration in the first study (CTCAE v5.0\> Grade 2), such as severe pneumonia, bacteremia, infection complications that require hospitalization; Active infection requiring intravenous anti-infective therapy or fever of unknown origin \> 38.5℃ occurred within 2 weeks prior to the first study administration (as determined by the investigators, subjects with fever due to tumors could be enrolled); 11.
