Regulus Therapeutics Inc. has provided an update on its preclinical studies evaluating a library of oligonucleotides designed to inhibit miR-155 for the treatment of amyotrophic lateral sclerosis (ALS).

Clene Inc. plans to sit down in the third quarter of this year with the U.S. FDA for talks about approval for gold nanocrystal suspension CNM-Au8, bolstered by favorable biomarker findings in amyotrophic lateral sclerosis (ALS) from the phase II/III Healey ALS platform trial – along with a sizeable time-to-event and survival data package that should drive the conversation.

Lack of efficacy brought the development of two investigational agents for amyotrophic lateral sclerosis (ASL) to a halt over the past week. On May 23, Wave Life Sciences Inc. disclosed that its stereopure antisense oligonucleotide WVE-004 failed to demonstrate clinical benefit after 24 weeks of treatment on a phase Ib/IIa trial in familial ALS patients or frontotemporal dementia patients. And on May 25, Apellis Pharmaceuticals Inc. and its partner, Swedish Orphan Biovitrum International AB, said that pegcetacoplan failed to meet its primary endpoint of a one-year phase II trial in patients with sporadic disease.

Merck Sharp & Dohme Corp. has disclosed receptor-interacting serine/threonine-protein kinase 1 (RIPK1; RIP-1) inhibitors reported to be useful for the treatment of amyotrophic lateral sclerosis and inflammation.
