The purpose of this study is to investigate the safety, PK, and immunogenicity of a single intravenous administration of HLX6018 in healthy subjects, based on the preliminary efficacy and safety established through in vitro and in vivo experiments.
This is a randomized, double-blind, placebo-controlled study with single dose escalation design to assess the safety, PK, and immunogenicity of HLX6018 in healthy subjects. It is planned to enroll 8-10 subjects in each of seven dose groups (0.25 mg/kg, 1.0 mg/kg, 4.0 mg/kg, 12 mg/kg, 25 mg/kg, 50 mg/kg, and 70 mg/kg). This is the first-in-human study of the investigational product.

Non-Squamous Non-Small Cell Lung Cancer (NSCLC) remains a leading cause of cancer mortality worldwide, with poor survival prospects for metastatic disease. The purpose of this study is to evaluate the optimized dose, adverse events, and efficacy of livmoniplimab in combination with budigalimab plus chemotherapy versus pembrolizumab plus chemotherapy in participants with untreated metastatic non-squamous non-small cell lung cancer.
Livmoniplimab is an investigational drug being developed for the treatment of NSCLC. There are 2 stages to this study. In Stage 1, there are 4 treatment arms. Participants will either receive livmoniplimab (at different doses) in combination with budigalimab (another investigational drug) + chemotherapy, budigalimab +chemotherapy, or pembrolizumab +chemotherapy. In Stage 2, there are 2 treatments arms. Participants will either receive livmoniplimab (optimized dose) in combination with budigalimab +chemotherapy or placebo in combination with pembrolizumab +chemotherapy. Chemotherapy consists of IV Infused pemetrexed + IV infused cisplatin or IV infused or injected carboplatin. Approximately 840 adult participants will be enrolled in the study across 200 sites worldwide.
Stage 1: In cohort 1, participants will receive intravenously (IV) infused livmoniplimab (dose A)+ IV infused budigalimab, + chemotherapy for 4 cycles followed by livmoniplimab + budigalimab + IV Infused pemetrexed. In cohort 2, participants will receive livmoniplimab (dose B) + budigalimab + chemotherapy for 4 cycles followed by livmoniplimab + budigalimab + pemetrexed. In cohort 3, participants will receive budigalimab + chemotherapy for 4 cycles followed by budigalimab + pemetrexed . In cohort 4, participants will receive IV Infused pembrolizumab + chemotherapy for 4 cycles followed by pembrolizumab + pemetrexed. Stage 2: In arm 1, participants will receive livmoniplimab (dose optimized) + budigalimab + chemotherapy for 4 cycles followed by livmoniplimab + budigalimab + pemetrexed. In arm 2, participants will receive IV Infused placebo + pembrolizumab + chemotherapy for 4 cycles followed by pembrolizumab + pemetrexed. The estimated study duration is 55 months.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, questionnaires, and scans.

Hepatocellular carcinoma (HCC) is a common cancer worldwide and a leading cause of cancer-related death. The majority of participants first presenting with HCC have advanced unresectable or metastatic disease. The purpose of this study is to evaluate the optimized dose, adverse events, and efficacy of livmoniplimab in combination with budigalimab.
Livmoniplimab is an investigational drug being developed for the treatment of HCC. There are 2 stages to this study. In Stage 1, there are 3 treatment arms and participants will be randomized in a 1:1:1 ratio. Participants will either receive livmoniplimab (at different doses) in combination with budigalimab (another investigational drug), atezolizumab in combination with bevacizumab, or tremelimumab in combination with durvalumab. In Stage 2, there are 2 treatments arms and participants will be randomized in a 1:1 ratio. Participants will either receive livmoniplimab (optimized dose) in combination with budigalimab or tremelimumab in combination with durvalumab. Approximately 660 adult participants will be enrolled in the study across 185 sites worldwide.
Stage 1: In arm 1, participants will receive intravenously (IV) infused livmoniplimab (Dose 1) in combination with IV infused budigalimab, every 3 weeks. In arm 2, participants will receive IV infused livmoniplimab (Dose 2) in combination with IV infused budigalimab, every 3 weeks. In Arm 3 (control), participants will receive the investigator's choice: IV atezolizumab in combination with IV bevacizumab every 3 weeks or single dose IV tremelimumab in combination with IV durvalumab every 4 weeks. Stage 2: In arm 1, participants will receive IV infused livmoniplimab (optimized dose) in combination with IV infused budigalimab, every 3 weeks. In Arm 2 (control), participants will receive single dose IV tremelimumab in combination with IV durvalumab every 4 weeks. All participants will continue treatment until disease progression or discontinuation criteria are met, whichever occurs first. The estimated duration of this study is about 56 months.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic and may require frequent medical assessments, blood tests, questionnaires, and scans.
