Brief Summary:
This study is the first-in-human clinical trial of CN1 to evaluate the safety, tolerability, pharmacokinetic (PK) profile and preliminary efficacy of CN1 in patients with advanced solid tumors or B-cell lymphoma. This study will provide a basis for further clinical development of CN1.

Condition or disease Intervention/treatment Phase
Advanced Solid Tumor B Cell Lymphoma Drug: CN1 Phase 1

Detailed Description:

CN1 could promote T cell activation and cytokine secretion, thereby enhancing the function of CD4+ and CD8+ T cells, and could also regulate Treg cells, thus CN1 is considered to enhance the anti-tumor immune response and have potential antitumor activity.

In this multicenter, open-label, dose-escalation Phase I study six dose levels are planned. Participants will receive CN1 by IV infusion on Day 1 of each cycle (every 3 weeks). After completion of treatment cycles, the participant will be assessed by the Principal Investigator and/or Safety Monitoring Committee (SMC).

Arm Intervention/treatment
Experimental: Single Arm

Five planned CN1 dose levels of 0.03 mg/kg, 0.3 mg/kg, 1 mg/kg, 3 mg/kg, and 10 mg/kg.

Subjects will receive CN1 by intravenous infusion (IV) on Day 1 (D1) of each cycle (once every 3 weeks per cycle).

Drug: CN1
Participants will receive CN1 by IV infusion on Day 1 of each cycle (every 3 weeks). The 5 planned dose levels are 0.03 mg/kg, 0.3 mg/kg, 1 mg/kg, 3 mg/kg and 10 mg/kg.




Primary Outcome Measures :
  1. To determine dose-limiting toxicity (DLT), maximum tolerated dose (MTD), and/or recommended Phase II dose (RP2D) of CN1 administered to patients with advanced solid tumor or B-cell lymphoma. [ Time Frame: 21 Days after the first dose i.e. starting dose level 0.03 mg/kg ]
    DLT is measured in the observation period of 21 days after the first dose i.e. starting dose level 0.03 mg/kg. if the enrolled subject does not experience a study drug related Grade 2 or higher adverse event (AE) per NCI-Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0, the subject will start to receive the next designated dose level of 0.3 mg/kg in the second 21 days dosing cycle.


Secondary Outcome Measures :
  1. To assess the safety and tolerability of CN1 in patients with advanced solid tumor or B-cell lymphoma through Physical Exam [ Time Frame: From baseline(Week 1) to 90 days after the last dose ]
    Measured by incidence of abnormal physical examination findings.

  2. To assess the safety and tolerability of CN1 in patients with advanced solid tumor or B-cell lymphoma through Adverse Events/Serious Adverse Events [ Time Frame: From baseline(Week 1) to 90 days after the last dose ]
    Measured by incidence of Adverse Events/Serious Adverse Events. All AEs will be summarized according to the Medical Dictionary for Regulatory Activities (MedDRA) v23.0 or higher and the severity will be categorized by CTCAE v5.0. The summary of all AEs will be focused on the treatment-emergent adverse events (TEAEs). A TEAE is defined as any AE that starts after the first dose of study drug till 90 +/- 7 days after the last dose of study drug.

  3. To assess the pharmacokinetic (PK) profile of CN1 in patients with advanced solid tumor or B-cell lymphoma through Area under the plasma concentration-time curve [ Time Frame: Measurement is through treatment completion starting from Week 1 up to End of Treatment, assessed up to an average of 10 weeks. ]
    The following parameter is used for evaluation during PK assessments: Area under the plasma concentration-time curve (AUC0-t, AUC0- ∞, AUC0-τ)

  4. To assess the pharmacokinetic (PK) profile of CN1 in patients with advanced solid tumor or B-cell lymphoma through Tmax [ Time Frame: Measurement is through treatment completion starting from Week 1 up to End of Treatment, assessed up to an average of 10 weeks. ]
    The following parameter is used for evaluation during PK assessments: Time to maximum (Tmax)

  5. To assess the pharmacokinetic (PK) profile of CN1 in patients with advanced solid tumor or B-cell lymphoma through Apparent volume of distribution at steady state [ Time Frame: Measurement is through treatment completion starting from Week 1 up to End of Treatment, assessed up to an average of 10 weeks. ]
    The following parameter is used for evaluation during PK assessments: Apparent volume of distribution at steady state (Vss)

  6. To assess the pharmacokinetic (PK) profile of CN1 in patients with advanced solid tumor or B-cell lymphoma through Accumulation factor based on AUC 0-τ [ Time Frame: Measurement is through treatment completion starting from Week 1 up to End of Treatment, assessed up to an average of 10 weeks. ]
    The following parameter is used for evaluation during PK assessments: Accumulation factor based on AUC 0-τ (R AUC0-τ)

  7. To assess the immunogenicity to CN1 in patients with advanced solid tumor or B-cell lymphoma through ADA testing [ Time Frame: Measurement is through treatment completion starting from Week 1 up to End of Treatment, assessed up to an average of 10 weeks. ]
    A validated analysis method will be used for detection of anti-drug antibodies (ADA).

  8. To explore the anti-tumor efficacy of CN1 in patients with advanced solid tumor or B-cell lymphoma through ORR analysis [ Time Frame: Measurement is from Week 1, until the 90 days after the last dose, date of first documented progression or unacceptable toxicity, withdrawal of consent, subject being lost to follow-up, or death, whichever occurs first. ]
    Assessed by the number of participants with objective response (ORR)

  9. To explore the anti-tumor efficacy of CN1 in patients with advanced solid tumor or B-cell lymphoma through DCR analysis. [ Time Frame: Measurement is from Week 1, until the 90 days after the last dose, date of first documented progression or unacceptable toxicity, withdrawal of consent, subject being lost to follow-up, or death, whichever occurs first. ]
    Assessed by the number of participants with Disease Control (DCR)

  10. To explore the anti-tumor efficacy of CN1 in patients with advanced solid tumor or B-cell lymphoma through DoR analysis. [ Time Frame: Measurement is from Week 1, until the 90 days after the last dose, date of first documented progression or unacceptable toxicity, withdrawal of consent, subject being lost to follow-up, or death, whichever occurs first. ]
    Assessed by the number of participants with Duration of Response (DoR)
