Phase 2 Multi-center Randomized Study to the Efficacy and Safety of AK105 Combined With Anrotinib Hydrochloride in Patients With Recurrent/Refractory Classical Hodgkin's Lymphoma

• Status: Enrolling by invitation
• Trial end date: 2026-05-31
• Target enrollment: 0
• Participant gender: All

Summary

This study is a single arm, open, multi center phase II exploratory study. To evaluate the efficacy and safety of AK105 combined with androtinib hydrochloride capsule in patients with relapsed/refractory classical Hodgkin's lymphoma (relapse or progression after autologous stem cell transplantation, or relapse progression after autologous stem cell transplantation but ≥ 1 line systemic multi drug combination chemotherapy). After screening, the subjects met the inclusion criteria and did not meet the exclusion criteria, and then entered the treatment period. They received AK105 injection (once every three weeks, 200mg/time, intravenous infusion) combined with androtinib hydrochloride capsule (once a day, 10mg each time, and stopped for one week for two consecutive weeks). Every 21 days was a treatment cycle until disease progression/intolerance occurred or the sponsor terminated the study. Patients with complete remission (CR) continue to receive 4 cycles of treatment, and then further consolidate treatment every 9 weeks within 1 year of continuous CR, and can stop treatment after 1 year of continuous CR. At the end of the trial, the subjects who can still benefit from the study treatment as judged by the investigator will continue to be provided with the trial drug. The longest administration time of AK105 combined with androtinib hydrochloride capsules shall not exceed 2 years.

3. The patient was diagnosed as classical Hodgkin's lymphoma (cHL) by histopathology (the histopathological diagnosis is based on the pathological specimen of tumor tissue within 3 years before the first administration, and confirmed by the center; if more than 3 years later, the patient needs to be diagnosed by biopsy in the research center);

4. The subject must be a cHL with recurrence (disease progression confirmed after recent treatment) or intractable (complete or partial remission failed after recent treatment), and must meet any of the following criteria: a) receive autologous stem cell transplantation after rescue chemotherapy, and then relapse or progress; b) For subjects who cannot or do not want to receive autologous stem cell transplantation, they are required to have received ≥ first-line standard systemic treatment (including PD-1 treatment); For patients who are difficult to treat, it means that the course of treatment ≥ 2 cycles fails to reach PR, or the treatment ≥ 4 cycles fails to reach CR. If the best effect or the reason for the end of treatment is PD, the number of courses of treatment is not required; For patients with recurrence, they have at least received first-line chemotherapy in the near future before recurrence;

5. Those who have used chemotherapy drugs before the first administration need to stop taking drugs for more than 4 weeks (mitomycin or nitrosoureas, more than 6 weeks), those who have received surgery, molecular targeted therapy, traditional Chinese medicine treatment with anti-tumor indications, and radiotherapy need to stop taking drugs for more than 4 weeks, and those who have used antibody drugs (such as brentuximab vedotin) need to stop taking drugs for more than 12 weeks, In addition, all adverse events (except hair loss) occurred in the treatment have been stabilized and returned to the standard level of admission and discharge or ≤ Grade 1 toxicity (NCI CTCAE Version 5.0);

6. According to CT or MRI evaluation, there is at least one tumor lesion that can be measured by imaging in two vertical directions (according to the 2014 Lugano standard, the length of intranodal lesions is>15mm, and the longest diameter of extranodal lesions is>10mm);

7. The main organs function well and meet the following standards:

i. The blood routine examination was in line (no blood transfusion and correction with hematopoietic stimulator drugs within 14 days before screening): hemoglobin (HGB) ≥ 80 g/L; Neutrophil absolute value (NEUT) ≥ 1.0 × 109/L； Platelet count (PLT) ≥ 80 × 109/L； ii. Biochemical examination shall meet the following requirements: total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN (lymphoma involving liver or biliary obstruction ≤ 5 × ULN）； Serum creatinine (Cr) ≤ 1.5 × ULN or creatinine clearance ≥ 50ml/min; iii. The blood coagulation function test shall meet the following requirements: prothrombin time (PT), activated partial thromboplastin time (APTT), and international normalized ratio (INR) ≤ 1.5 × ULN (without anticoagulation treatment); Iv. Color Doppler echocardiography evaluation: left ventricular ejection fraction (LVEF) ≥ 50%.

8. Female subjects of childbearing age should agree to use contraceptive measures (such as intrauterine device, contraceptive pill or condom) during the study period and within 6 months after the end of the study; The serum or urine pregnancy test was negative within 7 days before the study was included, and must be non lactating subjects; Male subjects should agree to use contraception during the study period and within 6 months after the end of the study period.
