Advanced Solid Tumor
Conditions
Brief summary
This study is a first-in-human, multicenter, open label, uncontrolled, non-randomized, phase 1a/1b study, to evaluate the safety, tolerability, and preliminary antitumor activity of NB002 in subjects with advanced solid tumors.
Detailed description
This study is a first-in-human, multicenter, open-label, uncontrolled, non-randomized, phase 1a/1b study. The study consists of a dose escalation part and a dose expansion part. In the escalation part, the primary objectives are to characterize the safety, tolerability, and dose-limiting toxicities (DLTs) to establish a preliminary recommended Phase 2 dose (RP2D) and/or a maximum tolerated dose (MTD) or maximum administered dose (MAD) of NB002. The expansion part is to further evaluate the safety and tolerability of NB002 at the RDE dose established in the dose escalation part and to explore antitumor activity in the selected population. All subjects will be treated with NB002 via IV infusion at predefined dose levels Q3W on Day 1 of each 21-day Cycle. The design of the dose escalation part will be provided below. Further details on dose expansion part will be updated later once more information on potentially benefiting tumor types is confirmed.

Inclusion criteria
1. Male or female ≥18 years of age at the time of signing informed consent. 2. Diagnosis of histological or cytological confirmed locally advanced, recurrent and/or metastatic solid tumors that failed to respond to standard therapy, intolerant/refractory to currently available local therapies, or for whom no appropriate therapies are available (based on the judgement of the Investigator). 3. Measurable or non-measurable disease according to RECIST 1.1 in dose escalation stage and at least one measurable lesion is necessary for dose expansion stage. 4. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1, and anticipated life expectancy of ≥ 3 months. 5. Adequate hematologic function based on the following (with no blood transfusion or hematopoietic stimulating factor therapy within 14 days prior to study drug administration): 1. ANC≥1.2 ×10\^9/L 2. Platelet count ≥75×10\^9/L 3. Hemoglobin ≥8.0 g/dL 6. Adequate coagulation parameters based on the following: 1. Prothrombin Time-International Normalized Ratio (PT-INR) ≤1.5×ULN (upper limit of normal), unless coumarin derivatives are used. 2. Activated partial thromboplastin time (aPTT) ≤1.5×ULN. Subjects on anticoagulants may have coagulation parameters that exceed the criteria defined above. 7. Adequate hepatic function based on the following: 1. Total bilirubin (TBIL) ≤1.5 × ULN and/or isolated elevations of indirect bilirubin are eligible for study participation. 2. Alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ≤3 × ULN (≤5 × ULN for subjects with known hepatic metastases). 8. Adequate renal function based on serum creatinine clearance ≥30 mL/min (normal to moderate renal impairment) as determined by Cockcroft-Gault equation. 9. A female patient is eligible to participate if she is not pregnant or breastfeeding, and * is not a WOCBP or * A WOCBP must have a negative pregnancy test within 72 hours before the first dose of study drug administration, and additional pregnancy testing during and after study drug as defined in the SOA . * A WOCBP must consent to use highly effective contraceptive methods or abstain from heterosexual activity from screening through 120 days following the last dose of study treatment. 10. Fertile male subjects, defined as all males physiologically capable of conceiving offspring, with their WOCBP partner(s) must agree to use highly effective contraception. Sexually active males who have not had a vasectomy, and whose partner is reproductively capable, must agree to abstain from sexual intercourse or use barrier contraception from Screening through 120 days following the last dose of study treatment. 11. Ability to understand and give written informed consent for participation in this trial, including all evaluations and procedures as specified by this protocol.
Exclusion criteria
1. Inadequate recovery from any prior surgical procedure, or patients having undergone any major surgical procedure within 4 weeks prior to first administration of study drug. 2. Has had a known or suspected hypersensitivity reaction to treatment with a mAb and/or the excipients of NB002. 3. Prior treatment with other TIM-3 inhibitors (e.g., mAbs). 4. Prior palliative radiotherapy within 1 week of start of study treatment. Subjects must have recovered (CTCAE Grade ≤1) from all radiation-related toxicities. 5. Any antitumor agent for the primary malignancy without delayed toxicity within 4 weeks or 5 half-lives, whichever is shorter, prior to first administration of study drug, except for Nitrosoureas and mitomycin C within 6 weeks prior to first administration of study drug and during study. 6. Active CNS metastases, however, subjects who have undergone definitive radiation and/or surgery for the treatment of CNS metastases, who are stable by radiographic and clinical (neurological) assessment (performed within 4 weeks prior to first trial drug administration), and who are no longer taking pharmacologic doses of corticosteroids are eligible; subjects with leptomeningeal metastases or primary CNS malignancies (such as glioma, glioblastoma) are not eligible. 7. Evidence of metastatic ileus on computed tomography (CT) scan. 8. Patients with concurrent hematologic malignancies. 9. Known active or prior infection with human immunodeficiency virus (HIV), or active infection with hepatitis B virus (HBV), or hepatitis C virus (HCV). 10. Any other serious/active/uncontrolled infection, any infection requiring parenteral antibiotics, or unexplained fever \> 38ºC within 2 weeks prior to first administration of study drug. 11. Patients with an active, known or suspected autoimmune disease, or a documented history of autoimmune disease or syndrome, requiring systemic steroids or other immunosuppressive medications. procedure is allowed if all other inclusion/
