Efficacy

Beleodaq (Belinostat) for the Treatment of Lymphoma

Beleodaq (belinostat) is a histone deacetylase inhibitor approved by the U.S. Food and Drug Administration (FDA) for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). This is a type of non-Hodgkin lymphoma that affects the T-cells of the immune system. The efficacy of Beleodaq was evaluated in a multicenter, single-arm trial that involved patients with refractory or relapsed PTCL. In this study, Beleodaq demonstrated a 25.8% overall response rate with a median duration of response of 8.4 months, which provided evidence for its clinical benefit in this patient population.

While Beleodaq has shown efficacy in PTCL, its effectiveness in other types of lymphoma has not been established. It is important for patients to understand that the use of Beleodaq for conditions other than PTCL is considered off-label, and its efficacy for such uses has not been confirmed by the FDA. The safety and effectiveness of Beleodaq continue to be monitored in post-marketing surveillance and ongoing clinical trials.

Rylaze (Asparaginase Erwinia Chrysanthemi (Recombinant)-rywn) for the Treatment of Lymphoma

Rylaze, also known as asparaginase erwinia chrysanthemi (recombinant)-rywn, is an asparagine-specific enzyme approved by the FDA as a component of a multi-agent chemotherapeutic regimen for acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL). The drug is indicated for patients who have developed hypersensitivity to E. coli-derived asparaginase. Rylaze works by depleting the amino acid asparagine, which is essential for the growth of ALL and LBL cells, leading to cell death. The efficacy of Rylaze was supported by a clinical trial where the drug maintained nadir serum asparaginase activity above the threshold believed to be therapeutic in 94% of patients, indicating its effectiveness in this patient population.

It is important to note that while Rylaze is used in the treatment of LBL, a type of non-Hodgkin lymphoma, its use is specifically for the lymphoblastic form. The efficacy of Rylaze in other types of lymphoma or for off-label uses has not been established. As with all medications, the use of Rylaze should be guided by a healthcare professional with consideration of the individual patient's diagnosis and treatment plan.
