Brief summary
Identification of T cell inhibitory signals, including PD-1/PD-L1, has prompted the development of a new class of cancer immunotherapy that could restore an adequate immunosurveillance against the neoplasm and enhance T-cell-mediated anticancer immune responses. However, elimination of cancer by T cells is only one step in the Cancer-Immunity Cycle, which enable providing several therapeutic targets and tailoring of combinations of immune therapies. Manganese has been confirmed to activate antigen-presenting cells and function as mucosal immunoadjuvants in pre-clinical studies. This study is a first-in-man, Phase I, 3 + 3 dose escalation study of a combined regimen of Manganese and anti-PD-1 antibody with or without chemotherapies in subjects with unresectable/ metastatic solid tumors or lymphomas. This study is designed to assess the safety, tolerability, pharmacokinetic profile (PK profile), mode of delivery and Recommended Phase 2 Dose (RP2D) of this regimen.
Interventions
Administered intranasally in Arm 1 (0.05, 0.1 or 0.2 mg/kg/d) and by inhalation in Arm 2 (0.1, 0.2 or 0.4mg/kg/d) once daily in a 3-week cycle
Administered intravenously, at 2-4mg/kg on day 3 in a 3-week cycle
COMBINATION_PRODUCTSystemic therapy
Whether and which should be given depends on the treatment regimen before enrollment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Subjects with treatment-related adverse events (AEs) | Approximately 6 months | Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0. AEs were considered to be treatment-related if they had started or worsened within the interval from first study drug administration until the follow-up visit. |
| Number of subjects with specific Manganese-related adverse events | Approximately 6 months | Manganese-related AEs were considered to be that start or worsen after administration Manganese administration，improve after withdrawal, and even occur again after re-administration. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Preliminary efficacy evaluation | Approximately 6 months | Objective response rate (ORR) and disease control rate (DCR) will be evaluated by investigators per the RECIST V1.1. |
| The q3w pharmacokinetic profile of Manganese | Approximately 3 months | PK parameters such as Maximum concentration (Cmax) are assessed. |
| Number of participants with laboratory test abnormalities | Approximately 3 months | The laboratory tests of serum cytokines and chemokines will be performed on day 1 and 3 of each cycle, and the abnormality will be determined by the investigator. |
