Inhibitor Comments
Aravive-S6 (MYD1-A72V, MYD1-72) is a preclinical, engineered fusion protein that acts as a soluble AXL decoy receptor, designed to overcome the potent binding between AXL and its endogenous ligand growth arrest specific protein 6 (GAS6) [4]. Structurally it is a fusion of AXL (with an Ala72Val substitution) and human IgG1 Fc. The affinity of this fusion vs. GAS6 is ~0.09pM (the AXL-GAS6 affinity is around 30pM) [10]. MYD1-A72V is reported to improve the efficiency of chemotherapies in preclinical models [10].
Antibody Comments
Genmab have an anti-AXL antibody-drug conjugate (HuMax-AXL-ADC, enapotamab vedotin) in their oncology developent pipeline. The ADC delivers a toxic monomethyl auristatin E (MMAE, a microtubule disrupting agent) payload to targeted cancer cells. Phase 1/2 trial NCT02988817 is evaluating HuMax-AXL-ADC in several types of solid tumours. The INN tilvestamab has been requested for another anti-AXL monoclonal (INN proposed list 121, August 2019), although the developer is unclear at this time.

Immunopharmacology Comments
All three TAM family receptor tyrosine kinases are involved in regulating inflammatory responses through a negative feedback loop. Specifically, AXL-Gas6 signalling is reported to induce autophagy in murine macrophages via inhibition of the NLRP3 inflammasome, an effect which reduces hepatic inflammation in a mouse model [8].
This protein contains an immunoglobulin (Ig)-like domain that resembles the antibody variable domain, that has been coined the 'V-set domain'. The genes for all human V-set domain containing proteins are listed in HGNC gene group 590.
General Comments
AXL has been suggested as providing an infection route for SARS-CoV-2 entry into pulmonary and bronchial epithelial cells, that is independent of the well established ACE2-mediated entry system [23]. Like ACE2-mediated infection, AXL also relys on interaction with the virus' spike protein, but the interaction occurs within the spike protein's N terminal domain, rather than with the highly studied ACE2 receptor binding domain (RBD).
