Alexion is collaborating with Caelum Biosciences to develop CAEL-101 for light chain (AL) amyloidosis, a rare systemic disorder that causes misfolded immunoglobulin light chain protein to build up in and around tissues, resulting in progressive and widespread organ damage. Alexion and Caelum Biosciences are conducting the Cardiac Amyloid Reaching for Extended Survival (CARES) Phase 3 clinical program to evaluate CAEL-101, a first-in-class amyloid fibril targeted therapy, in combination with standard-of-care therapy in AL amyloidosis. Two parallel Phase 3 studies - one in patients with Mayo stage IIIa disease and one in patients with Mayo stage IIIb disease - are underway. 

Alexion holds an exclusive license to develop and commercialize AG10 in Japan. Eidos is currently evaluating AG10 in two Phase 3 studies in the U.S. and Europe - one for ATTR cardiomyopathy (ATTR-CM) and one for ATTR polyneuropathy (ATTR-PN). Alexion is conducting a Phase 3 bridging study of ALXN2060 for patients with ATTR-CM in Japan.

ALXN2040 is an investigational, oral, factor D inhibitor. A Phase 3 study of ALXN2040 as an add-on therapy for PNH patients with EVH is underway. 

ANDEXXA has conditional approval in the U.S. and EU (marketed as ONDEXXYA in the EU) for the reversal of anticoagulation in patients experiencing life-threatening or uncontrolled bleeding who are treated with rivaroxaban or apixaban. The Phase 4 ANNEXA-I study - designed to provide clinical data supporting full approval - is underway to assess ANDEXXA compared to usual standard of care in patients presenting with acute intracranial hemorrhage while taking an oral Factor Xa inhibitor. A supplemental Biologics License Application (sBLA) is under review by the U.S. FDA to enable the addition of edoxaban and enoxaparin to the U.S. label. In February 2021, Alexion filed for regulatory approval of ONDEXXYA in Japan.

The results of this study will inform the design of a randomized controlled Phase 3 clinical trial to expand the label in this population.

ALXN1830 is a humanized monoclonal antibody that inhibits the interaction of neonatal Fc receptor (FcRn) with Immunoglobulin G (IgG) and IgG immune complexes and has the potential to improve treatment in a number of rare IgG-mediated diseases. Due to COVID-19, Alexion discontinued the Phase 2 study of ALXN1830, administered intravenously, in warm autoimmune hemolytic anemia (WAIHA) and the Phase 1 study of a subcutaneous formulation of ALXN1830 in healthy volunteers. In March 2021, Alexion initiated a new Phase 1 study of subcutaneous ALXN1830 in healthy volunteers. Following successful completion of this Phase 1 study, Alexion plans to initiate Phase 2 studies of subcutaneous ALXN1830 in gMG and WAIHA in 2021, pending regulatory feedback. 

ALXN1720 is a novel anti-C5 albumin-binding bi-specific mini-body optimized for sub-cutaneous delivery that binds and prevents activation of human C5. The Phase 1 healthy volunteer study of ALXN1720 has been paused for a second time due to COVID-19, but is expected to resume in the second quarter of 2021.
