This is a multicenter, single-arm, open-label, dose escalation phase (Part A) and dose expansion (Part B) study to evaluate the safety and tolerability of JLM019 Injection in patients with advanced malignancies. The study subjects are adults with advanced malignancies including advanced solid tumors or relapsed/refractory lymphoma. During the dose escalation phase, the dose escalation scheme is the accelerated titration in 0.001 - 0.2 mg/kg cohorts plus a traditional '3 + 3' design in 0.6 - 10 mg/kg cohorts, jointly in nine dose cohorts 0.001, 0.01, 0.05, 0.2, 0.6, 1.5, 3, 6 and 10 mg/kg. JLM019 Injection is intended to be administered once a week (QW). However, the dose and interval of administration may be adjusted based on the acquired PK, PD, and safety data. Each treatment cycle is 28 days.The repeated dose is tentatively scheduled to be administered once weekly until one of the following occurs: disease progression, intolerable toxicity, requirement for new antitumor therapy, withdrawal of informed consent form, death, loss to follow-up, or other protocol-specified discontinuation conditions. Safety profile, DLT, MTD and RED of JLM019 Injection shall be assessed during and after treatment, with PK, PD, immunogenicity and Efficacy analyzed correspondingly.
