Efficacy

Monjuvi (tafasitamab-cxix) for Lymphoma

Monjuvi (tafasitamab-cxix), in combination with lenalidomide, is approved for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low-grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT). Tafasitamab-cxix is a CD19-directed cytolytic antibody. The efficacy of Monjuvi was evaluated in a multicenter, single-arm trial, which demonstrated a significant therapeutic benefit in this patient population. The overall response rate (ORR) observed in the trial was a key indicator of its efficacy, with a considerable percentage of patients achieving either a complete or partial response to the treatment.

Xalkori (crizotinib) for Lymphoma

Xalkori (crizotinib) is primarily known for its use in the treatment of non-small cell lung cancer (NSCLC). However, its efficacy in lymphoma, particularly anaplastic large cell lymphoma (ALCL) that is anaplastic lymphoma kinase (ALK)-positive, has been a subject of clinical investigation. Crizotinib is an ALK inhibitor, and its off-label use in ALK-positive ALCL has shown promising results in some case reports and small studies. Nevertheless, the use of crizotinib in lymphoma is not as well established as its use in NSCLC, and its efficacy for lymphoma patients is not supported by large-scale, randomized clinical trials.

While the efficacy of Monjuvi in the treatment of DLBCL has been established through clinical trials leading to its approval for this indication, the evidence supporting the efficacy of Xalkori in lymphoma is more limited and anecdotal. It is important for healthcare providers to consider the current evidence and guidelines when making treatment decisions for lymphoma patients and to weigh the potential benefits and risks of off-label drug use.

In conclusion, Monjuvi has demonstrated efficacy in the treatment of relapsed or refractory DLBCL, providing a valuable option for patients who are ineligible for ASCT. On the other hand, Xalkori's efficacy in lymphoma, particularly ALK-positive ALCL, requires further investigation through clinical trials to establish its role in the treatment paradigm of lymphomas. Patients and healthcare providers should engage in thorough discussions about the potential off-label use of Xalkori in lymphoma, considering the current scope of evidence and the individual patient's clinical scenario.
