Unfractionated heparin (UH) is a heterogenous preparation of anionic, sulfated glycosaminoglycan polymers with weights ranging from 3000 to 30,000 Da. It is a naturally occurring anticoagulant released from mast cells. It binds reversibly to antithrombin III (ATIII) and greatly accelerates the rate at which ATIII inactivates coagulation enzymes thrombin (factor IIa) and factor Xa. UH is different from low molecular weight heparin (LMWH) in the following ways: the average molecular weight of LMWH is about 4.5 kDa whereas it is 15 kDa for UH; UH requires continuous infusions; activated partial prothrombin time (aPTT) monitoring is required when using UH; and UH has a higher risk of bleeding and higher risk of osteoporosis in long term use.

Activation of the Raf-MEK-ERK signalling pathway is known to be implemented in several types of malignancies; thus, mitogen-activated protein kinase kinase (MEK) inhibitors such as selumetinib are important tools that can target the problematic overactivity of this pathway. Results from clinical trials investigating earlier developed MEK inhibitors were underwhelming. However, selumetinib demonstrated impressive efficacy and tolerability in Phase I trials, leading to its continued investigation for the treatment of various types of tumours in Phase II trials. Currently, the novel MEK 1 / 2 inhibitor, selumetinib, is approved solely for the treatment of Neurofibromatosis type 1 (NF-1) in a limited age group. NF-1 is considered rare, with an estimated incidence of 1/3000 individuals. It is a genetic, autosomal dominant condition resulting from mutations of the NF1 gene, which can lead to various complications, including the development of multiple tumours in the nervous system.[A193533,A193608] Some patients with this disorder develop plexiform neurofibromas (PN); however, this is considered relatively uncommon compared to other variants of NF-1. Luckily, the use of selumetinib in patients with NF-1 have shown efficacy in shrinking associated tumours and is linked to other positive clinical outcomes. Selumetinib was approved by the FDA on April 10, 2020. It was later approved by Health Canada on August 23, 2022.
