Phase 2 Study of AFM13 in Combination with AB-101 in Subjects with R/R HL and CD30+ PTCL
Purpose
AFM13-203 is a phase 2, open-label, multi-center, multi-cohort study with a safety run-in followed by expansion cohorts. The study is evaluating the safety and efficacy of AFM13 in combination with AB-101 in subjects with R/R classical HL and CD30-positive PTCL.

Inclusion Criteria
- Subjects with a diagnosis of FDG-avid relapsed or refractory classical HL OR select subtypes of FDG-avid CD30-positive relapsed or refractory PTCL - For subjects with R/R PTCL a pre-enrollment tumor biopsy positive for CD30 locally assessed by Ber-H2 targeted immunohistochemistry at ≥1% is mandatory (PTCL subtypes: PTCL-NOS, Angioimmunoblastic T-cell lymphoma, ALCL, anaplastic lymphoma kinase (ALK)-positive, ALCL, ALK-negative) - Subjects with R/R classical HL must have received at least two lines of therapy including one prior line of combination chemotherapy. Prior therapy must also have included brentuximab vedotin and a PD1 check point inhibitor. - Subjects with R/R PTCL must have received at least one prior line of combination chemotherapy. Subjects with ALCL subtype of PTCL must have received or been intolerant to brentuximab vedotin. - Subjects with R/R classical HL AND R/R PTCL: Prior ASCT is permitted if completed at least 3 months prior to the first dose of study treatment. Prior allogeneic stem cell transplantation will be permitted if completed at least 1 year from study enrollment and there are no signs or symptoms of GVHD. Prior CAR-T therapy is permitted if last CAR-T dose completed at least 6 months prior to the first dose of study treatment. - Ability to understand and sign the ICF
Exclusion Criteria
- Active central nervous system (CNS) involvement (untreated or uncontrolled parenchymal brain metastasis or positive cytology of cerebrospinal fluid) - Previous treatment with AFM13 or CBNK cells - History of a solid organ allograft, or an inflammatory or autoimmune disease likely to be exacerbated by IL-2 (including subjects requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease that may require systemic steroids or immunosuppressive agents - Treatment with any therapeutic mAb or immunosuppressive medications - Known active Hepatitis B or C defined per protocol - Active HIV Infection - History of any other systemic malignancy, unless previously treated with curative intent and the subject has been disease free for 2 years or longer - Active acute or chronic graft vs. host disease (GVHD) or GVHD requiring immunosuppressive treatment, clinically significant central nervous system (CNS) dysfunction

Detailed Description
The study will start with a safety run-in exploring AFM13/AB-101 combination treatment in subjects with classical HL. Two dose levels of AFM13 and AB-101, respectively, will be tested in 4 cohorts. Cohort 1 and 2 will enroll in parallel. Enrolment into Cohort 3 and 4 will start only if the combination treatment has been well tolerated. Following the safety run-in observation period, a thorough risk-benefit analysis will be performed to determine 2 of the 4 cohorts/dose levels that will be further evaluated in the main part of the study which will also include subjects with classical HL and will follow a Simon two-stage design. An additional exploratory cohort (Cohort 5) will enroll subjects with select CD30-positive PTCL subtypes after completion of the safety run-in. All subjects will be treated with AFM13/AB-101 for a maximum of 3 cycles (cycle length is 48-days).
