Objectives: Patients with classical Hodgkin lymphoma (cHL) relapsing after second‐line therapy have a dismal prognosis and novel approaches are required for this patient group. Based on promising (pre‐)clinical data and the favourable toxicity profile, we performed a phase II clinical trial with the JAK inhibitor ruxolitinib in patients with relapsed or refractory cHL (r/r cHL). Methods: Patients ≥18 years with histologically confirmed r/r cHL who failed second‐line treatment were included. Ruxolitinib was given orally at a dose of 25 mg twice daily in continuous 28‐day cycles until progression or unacceptable toxicity. Primary endpoint was the PET/CT‐based overall response rate (ORR; complete response (CR) or partial response (PR)) after 2 cycles; secondary endpoints included progression‐free (PFS) and overall survival (OS) as well as feasibility. The Jericho Trial adopted a 2‐stage phase 2 design (Simon 1989). Results: Among the 12 included patients in stage 1, 2 had a PR, 3 had a stable disease (SD) and 6 had progressive disease (PD) after two treatment cycles (ORR: 2/12 evaluable patients, 16.7%). Median PFS was 3.6 months, the 1‐year OS estimate was 50.6% (median not reached). The toxicity profile was favourable with only one grade IV adverse event (7.1%) reported. Conclusion: Ruxolitinib exhibited a favourable side effect profile but modest activity in r/r cHL. Although the formal stopping criterion after stage 1 was not met, the trial did not continue to stage 2 due to the low response and PFS rates observed in stage 1. [ABSTRACT FROM AUTHOR]

Classical Hodgkin lymphoma (cHL) is the most common hematological malignancy in young adults and can be cured in most cases. However, relapsed and refractory Hodgkin lymphoma, certain patient groups, such as elderly patients, and toxicity of first-line treatment still pose significant challenges. Consequently, new treatment options are needed. Recently, many new treatment concepts have been evaluated in clinical trials. Targeted drug-antibody conjugates and immune checkpoint inhibitors have decisively changed treatment approaches. This review aims to give a comprehensive overview of novel agents in Hodgkin lymphoma that have been recently or are currently being evaluated in clinical trials. In addition to dedicated sections on brentuximab vedotin (BV) and immune checkpoint inhibitors, other emerging substances and concepts are discussed. In doing so, this review compares trial results regarding safety and efficacy. A special focus lies on the effect novel agents will have on the different treatment settings faced by clinicians involved in the treatment of Hodgkin lymphoma. [ABSTRACT FROM PUBLISHER]

Targeted treatment of cancer with monoclonal antibodies has added to the beneficial outcome of patients. In an attempt to improve anti-tumor activity of monoclonal antibodies, multi-specific antibodies have entered the research arena. To date, only a few multi-specific constructs have entered phase III clinical trials, in contrast to classical monoclonal antibodies, which are the standard first-line therapy in several tumor entities. In this review, we will assess selected multi-specific antibodies in pre-clinical and clinical development that may be new treatment options for cancer patients in the very near future. We will further evaluate therapy modalities including the timely distribution or the combination of various therapeutic approaches and assess the potential role of multi-specific antibodies in cancer treatment.
