Clin Cancer Res 2021 May 27. Epub 2021 May 27.

Office of Hematology and Oncology, Food and Drug Administration.

The FDA granted accelerated approval for pralsetinib on September 4 for NSCLC and December 1, 2020 for thyroid cancer, for: 1) adult patients with metastatic fusion-positive non-small cell lung cancer (NSCLC), 2) adult and pediatric patients {greater than or equal to}12 years of age with advanced or metastatic -mutant medullary thyroid cancer (MTC) who require systemic therapy, and 3) adult and pediatric patients {greater than or equal to}12 years of age with advanced or metastatic fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate). Approval was based on the results of a multicenter, open-label, multi-cohort clinical trial (ARROW, NCT03037385), demonstrating substantial overall response rates (ORR) and durable responses in patients with altered tumors. ORRs within the approved patient populations ranged from 57% (95% CI: 46, 68) in patients with fusion-positive NSCLC previously treated with platinum chemotherapy to 89% (95% CI: 52, 100) in patients with fusion-positive thyroid cancer, with response duration of at least 6 months in most responders.

Rasburicase-Induced Methemoglobinemia.

Cureus 2021 Apr 10;13(4):e14406. Epub 2021 Apr 10.

Internal Medicine, Creighton University School of Medicine, Omaha, USA.

Methemoglobinemia occurs as iron in heme is oxidized to its ferric state, resulting in a decreased ability of hemoglobin to bind and release oxygen. Rasburicase is a recombinant urate-oxidase enzyme used in the prevention of tumor lysis syndrome. Methemoglobinemia can occur as a rare complication of treatment with rasburicase, primarily in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Read More

Medicine Service, Ralph H. Johnson VA Medical Center, Charleston, and.

Burkitt's lymphoma is a common cause of tumor lysis syndrome (TLS) and, in the era of aggressive utilization of prophylactic allopurinol and recombinant uricase enzyme, nephrologists are increasingly witnessing monovalent or divalent cation abnormalities without marked uric acid elevation. An 18-year-old male received his 1 cycle of intensive chemotherapy for Burkitt's lymphoma and developed TLS as defined by the Cairo Bishop criteria. Lactate dehydrogenase peaked at 9,105 U/L (range: 130 - 250) and was accompanied by acute kidney injury, including serum creatinine 2. Read More

TNB-486 induces potent tumor cell cytotoxicity coupled with low cytokine release in preclinical models of B-NHL.

MAbs 2021 Jan-Dec;13(1):1890411

Teneobio, Inc., Newark, CA, United States.

The therapeutic potential of targeting CD19 in B cell malignancies has garnered attention in the past decade, resulting in the introduction of novel immunotherapy agents. Encouraging clinical data have been reported for T cell-based targeting agents, such as anti-CD19/CD3 bispecific T-cell engager blinatumomab and chimeric antigen receptor (CAR)-T therapies, for acute lymphoblastic leukemia and B cell non-Hodgkin lymphoma (B-NHL). However, clinical use of both blinatumomab and CAR-T therapies has been limited due to unfavorable pharmacokinetics (PK), significant toxicity associated with cytokine release syndrome and neurotoxicity, and manufacturing challenges.

BMJ Case Rep 2021 Mar 16;14(3). Epub 2021 Mar 16.

Department of Hematology and Oncology, William Beaumont Hospital, Royal Oak, Michigan, USA

We report a case of a 91-year-old Caucasian woman with a history of chronic lymphocytic leukaemia who developed acute hypoxic respiratory failure (AHRF) requiring intubation for less than 24 hours after receiving rasburicase. Laboratory workup was significant for methemoglobinemia and acute anaemia, and blood film demonstrated evidence of oxidative haemolysis with bite cells. The patient was given a presumptive diagnosis of glucose-6-phosphate dehydrogenase (G6PD) deficiency and was managed conservatively with successful resolution of AHRF and stabilisation of haemoglobin level.
