Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Arm 1; chidamide in combination with camrelizumab and capecitabine	Drug: chidamide; Chidamide, an HDAC inhibitor; Drug: camrelizumab; Camrelizumab (AiRuiKa™), a programmed cell death 1 (PD-1) inhibitor being developed by Jiangsu Hengrui Medicine Co. Ltd, recently received conditional approval in China for the treatment of relapsed or refractory classical Hodgkin lymphoma. The drug is also being investigated as a treatment for various other malignancies, including B cell lymphoma, oesophageal squamous cell carcinoma, gastric/gastroesophageal junction cancer, hepatocellular carcinoma, nasopharyngeal cancer and non-squamous, non-small cell lung cancer.; Drug: capecitabine; Capecitabine is an oral prodrug of 5-fluorouracil (5-FU) and approved for treatment of various malignancies. Hereditary genetic variants may affect a drug's pharmacokinetics or pharmacodynamics and account for differences in treatment response and adverse events among patients.
Experimental: Arm 2; chidamide in combination with camrelizumab and carboplatin	Drug: chidamide; Chidamide, an HDAC inhibitor; Drug: camrelizumab; Camrelizumab (AiRuiKa™), a programmed cell death 1 (PD-1) inhibitor being developed by Jiangsu Hengrui Medicine Co. Ltd, recently received conditional approval in China for the treatment of relapsed or refractory classical Hodgkin lymphoma. The drug is also being investigated as a treatment for various other malignancies, including B cell lymphoma, oesophageal squamous cell carcinoma, gastric/gastroesophageal junction cancer, hepatocellular carcinoma, nasopharyngeal cancer and non-squamous, non-small cell lung cancer.; Drug: carboplatin; Carboplatin [diammine(1,1-cyclobutanedicarboxylato)platinum(II)] is one of the most promising second generation platinum compounds. Its greater chemical stability in comparison with cisplatin accounts for its lower reactivity with nucleophilic sites of DNA.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Response Rate (ORR)	ORR is the percentage of participants with the best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1. CR = Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to < 10 mm; PR = At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters.	Up to approximately 12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-Free Survival (PFS)	PFS defined as the time from the date of randomization to the first evidence of disease progression as defined by response evaluation criteria in solid tumors (RECIST) v1.1 or death from any cause. Progressive Disease (PD) was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions. If a participant does not have a complete baseline disease assessment, then the PFS time was censored at the date of randomization, regardless of whether or not objectively determined disease progression or death has been observed for the participant. If a participant was not known to have died or have objective progression as of the data inclusion cutoff date for the analysis, the PFS time was censored at the last adequate tumor assessment date.	Up to approximately 30 months
Overall Survival (OS)	Time from date of randomization to the date of death from any cause	Up to approximately 30 months]
Disease control rate(DCR)	DCR is defined as cases where objective remission(assessed as complete remission or partial remission according RECIST 1.1 standard) or stable disease during the study.	Up to approximately 12 weeks
Clinical Benefit Rate (CBR)	Percentage of participants with complete response (CR) or partial response (PR) or stable disease (SD) lasting 24 weeks or longer as defined in RECIST 1.1.CR = Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to < 10 mm; PR = At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters; SD = Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease: PD = At least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20% the sum must also demonstrate an absolute increase of at least 5 mm	Up to approximately 12 weeks
