Participant gender:

Summary
Young patients with relapsed or refractory classic Hodgkin's lymphoma will be treated with PD-1 inhibitor combined with decitabine as second-line salvage treatment for four cycles. If PR or CR was obtained after salvage treatment, patients will receive GBM conditioning regimen followed by ASCT as consolidation therapy. High-risk R/R cHL patients will be treated with PD-1 inhibitor after ASCT for 1 year. The purpose of current study is to determine the clinical efficacy and safety of PD-1 inhibitor combined with decitabine followed by ASCT as second-line treatment in patients with relapsed or refractory classic Hodgkin's lymphoma.

Criteria
Inclusion Criteria:

1. Subjects must have histological confirmation of relapsed or refractory classic Hodgkin
lymphoma (HL).

2. 18 to 65 years of age.

3. Subjects with lymphoma must have at least one measureable lesion >1 cm as defined by
lymphoma response criteria.

4. Proper functioning of the major organs: 1) The absolute value of neutrophils
(≥1×10^9/L); 2) platelet count (≥75×10^9/L); 3) Serum creatinine <1.5 times Upper
Limit Normal (ULN) ; 4) Serum total bilirubin < 1.5 times ULN; 5) Aspartate
Aminotransferase (AST), Alanine Aminotransferase (ALT) ≤3 times ULN; 6) Serum
creatinine (Cr) ≤2 ULN, or glomerular filtration rate ≥40ml/min; 7) Thyrotropin (TSH)
or free thyroxine (FT4) or free triiodothyronine (FT3) were all within the normal
range (±10%).

5. Eastern Cooperative Oncology Group (ECOG) Performance status 0-2.

6. LVEF value measured by echocardiography ≥50%.

7. Life expectancy > 3 months.

Exclusion Criteria:

1. Patients with central nervous system involvement by lymphoma.

2. Patients with active autoimmune diseases requiring systematic treatment in the past
two years (hormone replacement therapy is not considered systematic treatment, such as
type I diabetes mellitus, hypothyroidism requiring only thyroxine replacement therapy,
adrenocortical dysfunction or pituitary dysfunction requiring only physiological doses
of glucocorticoid replacement therapy); Patients with autoimmune diseases who do not
require systematic treatment within two years can be enrolled.

3. Known systemic vasculitides, primary or secondary immunodeficiency(such as HIV
infection or severe inflammatory disease).

4. Pregnant or breastfeeding women.

5. Major surgery within 4 weeks before enrollment.

6. Impaired cardiac function:Ejection fraction <50% on MUGA scan. QTc interval > 450msecs
on baseline ECG. Myocardial infarction within 6 months prior to starting study; other
clinically significant heart disease (e.g. unstable angina, congestive heart failure
or uncontrolled hypertension, uncontrolled arrhythmias).

7. Other concurrent severe and/or uncontrolled medical conditions: Patients with another
primary malignant disease, except those that do not currently require treatment; acute
or chronic liver, pancreatic or severe renal disease; another severe and/or
life-threatening medical disease.
