We present a retrospective multicenter study of pralatrexate treatment outcomes in an Australian practice setting for patients with relapsed/refractory T-cell lymphoma who had failed 1+ systemic therapies, treated via a compassionate access program. Endpoints assessed included response rates, toxicities, and subsequent therapies. Progression-free survival (PFS), time to next treatment (TTNT), event-free survival (EFS), overall survival (OS), and time to best response, were assessed by Kaplan–Meier analysis. The study included 31 patients, with median age 69 years. We demonstrated ORR of 35.5% (n = 11), including 4 complete responses (13%) and 7 partial responses (23%). The predicted median OS was 10 months, with EFS of 9 months, and PFS of 9 months. Median TTNT was 8 months. Mucositis was the most commonly observed toxicity. This study – the second largest real-world cohort reported to date – underscores the importance of pralatrexate in relapsed/refractory T-cell lymphoma, as well as its acceptable toxicity profile.

Roughly, 30-50% of patients with R/R DLBCL who achieve disease remission with salvage therapies relapse within 1 year of treatment [[3]]. The results of this pooled analysis suggest treatment with blinatumomab salvage therapy may lead to durable CR and survival benefit in patients with R/R DLBCL. Outcomes of diffuse large B-cell lymphoma patients relapsing after autologous stem cell transplantation: an analysis of patients included in the CORAL study. [Extracted from the article]

The phase 2 portion of this open-label phase 2/3 study assessed the efficacy and safety of blinatumomab as second salvage for aggressive relapsed or refractory (r/r) aggressive B-cell non-Hodgkin lymphoma (B-NHL) following platinum-based first salvage chemotherapy. Forty-one patients with aggressive disease (32% relapsed; 68% refractory) enrolled and received stepwise blinatumomab (9–28–112 μg/day) in a 70-day cycle 1 and an optional 28-day cycle 2; 19 (46%) completed cycle 1 and 3 (7%) completed cycle 2. The overall response rate after 12 weeks was 37%, including 9 (22%) complete metabolic responses. Eight (20%) patients (all responders) subsequently received stem cell transplants. Grade ≥3 adverse events were reported in 29 (71%) patients. Grade 3 cytokine release syndrome occurred in one patient. Grade 3 neurologic events occurred in 10 (24%) patients; all resolved. Blinatumomab monotherapy appears effective as second salvage therapy in patients with r/r aggressive B-NHL. Trial registration: NCT02910063. [ABSTRACT FROM AUTHOR]

The prognosis of AML in elderly patients is poor and research into novel therapeutic approaches is urgently needed. This study examined the use of low-dose chemotherapy with cytarabine and thioguanine administered in repetitive cycles in 62 elderly patients with newly diagnosed or relapsed/refractory AML. The overall response rate was 58% in the total cohort. Response rates (CR/CRi) were significantly higher in patients with newly diagnosed AML (74%) compared to patients with relapsed/refractory disease (25%, p =.0004). Kaplan–Meier estimate of overall survival was 289 days (95% CI; 183–395 days) with a relapse rate of 65.7%. The induction mortality rate was 16.1% with treatment successfully undertaken in the outpatient setting. Similar clinical outcomes were observed in a retrospective analysis of a second cohort of 25 AML patients treated at a different site. These results support the use of a sustained low intensity chemotherapy approach as a therapeutic option for elderly patients with AML. [ABSTRACT FROM AUTHOR]

Lymphomatoid granulomatosis (LYG) is a rare Epstein Barr virus (EBV)-associated lymphoproliferative disease. Even with combination chemotherapy, mortality is high. There is no standard therapy for relapsed or refractory disease. There is only one report in the literature of a complete remission with high-dose chemotherapy and autologous stem cell transplantation. This study presents the case of a patient with progressive LYG, who was successfully treated with autologous stem cell transplantation after conditioning with high-dose chemotherapy and total body irradiation. After transplantation, maintenance therapy with interferon alpha 2a was administered for 3.75 years. The patient remains well and in remission 8 years post-transplantation. This is the first report of a durable (>1 year) complete remission after high-dose chemotherapy and autologous stem cell transplantation in LYG. The role of high-dose chemotherapy and autologous stem cell transplantation in relapsed or refractory cases merits further evaluation. The exact place of interferon in treatment of LYG remains to be clarified but is promising. [ABSTRACT FROM AUTHOR]
