Interim PET/CT-adapted Use of PD-1 Inhibitor Combined With De-escalated Chemotherapy-AVD in Classic Hodgkin Lymphoma

July 18, 2026 updated by: Xiao-Jun Huang, Peking University People's Hospital

A Prospective Single-institution Phase II Study of Interim PET/CT-adapted PD-1 Inhibitor Addition to First-line Chemotherapy for Unfavorable Stage II and Stage III/IV Classical Hodgkin Lymphoma to Omit High-dose Chemotherapy and Radiotherapy

This study enrolls newly diagnosed unfavorable stage II /stage III-IV classical Hodgkin lymphoma patients. All participants receive 2 cycles ABVD induction chemotherapy, then stratified by interim PET-CT Deauville score for differentiated treatment: standard ABVD for DS1-3, AVD plus Sintilimab for DS4, salvage chemotherapy plus autologous stem cell transplant for DS5. The primary goal is to assess 2-year progression-free survival and compare long-term survival and toxicities across subgroups, to verify whether Sintilimab addition can avoid high-dose chemo-radiotherapy for DS4 patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: iPET2 Stratified ABVD-Based Treatment Arm

All patients receive 2 cycles of frontline ABVD induction chemotherapy first, then treatment is stratified by iPET2 Deauville score:

DS 1-3: Complete standard full-course ABVD chemotherapy; DS 4: AVD combined with Sintilimab maintenance to avoid high-dose chemo-radiotherapy; DS 5: Salvage intensive chemotherapy followed by autologous stem cell transplantation
Drug: ABVD chemotherapy
Combination chemotherapy containing Doxorubicin, Bleomycin, Vinblastine and Dacarbazine, 2 cycles as uniform frontline induction treatment for all eligible patients.
Drug: Sintilimab and AVD
Anti-PD-1 monoclonal antibody Sintilimab, combined with AVD chemotherapy and given as maintenance therapy for patients with iPET2 Deauville Score 4 to avoid high-dose chemo-radiotherapy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
2-year Progression-Free Survival (PFS)
Time Frame: 2 years after completion of all assigned treatment
Time from study enrollment to first disease progression or death from any cause, stratified by iPET2 Deauville score subgroups. Disease progression is confirmed by radiological imaging evaluation.
2 years after completion of all assigned treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
5-year Progression-Free Survival (PFS)
Time Frame: 5 years after completion of all assigned treatment
Long-term progression-free survival up to 5 years after treatment completion, compared across iPET2 stratified subgroups.
5 years after completion of all assigned treatment
Incidence of All-Grade and Grade 3-5 Adverse Events
Time Frame: Throughout treatment period and 5-year long-term follow-up
Rate of hematological, non-hematological and Sintilimab-related immune adverse events graded per CTCAE v5.0 during treatment and follow-up.
Throughout treatment period and 5-year long-term follow-up
