|---|---|---|---|
| Primary | Phase I: The maximum tolerated dose (MTD) and/or phase II recommended dose (RP2D) | 27 weeks | To evaluate the safety and tolerability of CYH33 and determine the maximum tolerated dose (MTD) and/or phase II recommended dose (RP2D) of CYH33 in adult and adolescent patients |
| Primary | Phase II PROS Cohort: BIRC-assessed objective response rate (ORR) at Week 24 | Baseline to 24weeks | Proportion of patients achieving ≥20% reduction from baseline in the sum of target lesion volumes, with no progression of non-target lesions and no new lesions, as assessed by blinded independent review committee (BIRC). |
| Primary | Phase II PRVM Cohort: BIRC-assessed objective response rate (ORR) at Week 24 | Baseline to 24weeks | Proportion of patients achieving ≥20% reduction from baseline in the sum of target lesion volumes, with no progression of non-target lesions and no new lesions, as assessed by blinded independent review committee (BIRC). |
| Secondary | Phase I: Pharmacokinetics of CYH33 and its metabolite I27 in the study population: Area Under the Curve from 0 to 24 hours (AUC0-24h) | Pre-dose and at 1, 2, 4, 6, 8, and 24 hours post-dose on Day 1 and Day 29. | AUC0-24h of CYH33 and its metabolite I27 following drug administration will be assessed. |
| Secondary | Phase I: Pharmacokinetics of CYH33 and its metabolite I27 in the study population: Maximum Concentration (Cmax) | Pre-dose and at 1, 2, 4, 6, 8, and 24 hours post-dose on Day 1 and Day 29. | Cmax of CYH33 and its metabolite I27 following drug administration will be assessed. |
| Secondary | Phase I: Pharmacokinetics of CYH33 and its metabolite I27 in the study population: Minimum Concentration (Cmin) | Pre-dose on Day 29. | Cmin of CYH33 and its metabolite I27 following drug administration will be assessed. |
| Secondary | Phase I: Pharmacokinetics of CYH33 and its metabolites in the study population: Time to Maximum Concentration (Tmax) | Pre-dose and at 1, 2, 4, 6, 8, and 24 hours post-dose on Day 1 and Day 29. | Tmax of CYH33 and its metabolite I27 following drug administration will be assessed. |
| Secondary | Phase I: Pharmacokinetics of CYH33 in the study population: Steady-State Apparent Clearance (CLss/F) | Pre-dose and at 1, 2, 4, 6, 8, and 24 hours post-dose on Day 1 and Day 29. | CLss/F of CYH33 following drug administration will be assessed. |
| Secondary | Phase I: The response rate and target lesion volume reduction rate as assessed by the investigators at each dose level | week 27 | A responder is defined as a ≥ 20% reduction in target lesion volume from baseline and in absence of progression of non-target lesions and without new lesions. The proportion of patients with reduced target lesion volume compared to baseline will also be assessed. |
| Secondary | Phase I: The changes from baseline in the Brief Pain Inventory (BPI) Worst Pain Intensity Numerical Rating score at each dose level, based on the patient-reported outcome (PRO) diary | Up to approximately 48 months | Pain is categorized into 11 levels from 0 to 10, where 0 indicates no pain at all and 10 indicates the most severe pain imaginable. Patients should assess and record their pain levels over the past 24 hours in the patient diary at each scheduled assessment visit. |
| Secondary | Phase I: The changes from baseline in the Patient Global Impression of Change scale at each dose level, based on the patient-reported outcome (PRO) diary | Up to approximately 48 months | Patients will compare their global impression of symptom changes with the pretreatment status, then categorize them into the following 7 grades: significantly relieved, moderately relieved, minimally relieved, no change, minimally worse, moderately worse, or significantly worse at each scheduled assessment visit. |
| Secondary | Phase I: The changes from baseline in the quality of life scores at each dose level, based on the patient-reported outcome (PRO) diary | Up to approximately 48 months | The Quality of Life Scale (EQ-5D-5L) consists of two parts. Part 1 assesses five quality-of-life-related indicators, with each indicator graded into five distinct levels for self-evaluation by the patient. Part 2 consists of patients' self-assessment of health status, with a maximum score of 100 points and a minimum score of 0 points. |
| Secondary | Phase I: Frequency and severity of adverse events | Up to approximately 48 months | The type, incidence, and severity of adverse events (AEs) (assessed according to the CTCAE Version 5.0 criteria). |
| Secondary | Phase II : BIRC-assessed ORR at Week 48 (PROS cohort and PRVM cohort) | Week 48 | BIRC-assessed ORR at Week 48 (PROS cohort and PRVM cohort) Time Frame: From start of CYH33 treatment to Week 48 |
| Secondary | Phase II: BIRC-assessed ORR at Week 8 (Double-blind Period in PRVM cohort) | Week27 | BIRC-assessed ORR at Week 8 (Double-blind Period in PRVM cohort) Time Frame: From randomization to Week 8 |
| Secondary | Phase II: BIRC-assessed ORR at Weeks 8 and 16 (PROS cohort and PRVM cohort) | Weeks 8 and Week 16 | BIRC-assessed ORR at Weeks 8 and 16 (PROS cohort and PRVM cohort) Time Frame: From start of CYH33 treatment to Weeks 8 and 16 |
| Secondary | Phase II : Change from Baseline in Target Lesion Volume (PROS cohort and PRVM cohort) | Up to approximately 48 months | Change from Baseline in Target Lesion Volume (PROS cohort and PRVM cohort) Time Frame: From start of CYH33 treatment to Week 48 |
| Secondary | Phase II: Investigator-assessed overall clinical response (PROS cohort and PRVM cohort) | Up to approximately 48 months | Investigator-assessed overall clinical response (PROS cohort and PRVM cohort) Time Frame: From start of CYH33 treatment to Week 48 |
| Secondary | Phase II: Change from Baseline in Patient-Reported Outcomes (PROS cohort and PRVM cohort) | Up to approximately 48 months | Change from Baseline in Patient-Reported Outcomes (PROS cohort and PRVM cohort) Time Frame: Up to approximately 48 months |
| Secondary | Phase II: Safety and Tolerability of CYH33 (PROS cohort and PRVM cohort) | Up to approximately 48 months | Safety and Tolerability of CYH33 (PROS cohort and PRVM cohort) Time Frame: Up to approximately 48 months |
