Positive Clinical Data Announcement by Largest Portfolio Holding - Avidity Biosciences

RTW Biotech Opportunities Ltd (the "Company"), a London Stock Exchange-listed investment company focused on identifying transformative assets with high growth potential across the life sciences sector, is pleased to note the announcement on 12th June by its largest portfolio holding, Avidity Biosciences Inc. ("Avidity") (Nasdaq: RNA) of positive initial data from its Phase 1/2 trial of AOC 1020, an investigational therapy that targets DUX4, the root cause of facioscapulohumeral muscular dystrophy (FSHD). AOC 1020 demonstrated unprecedented and consistent reductions of greater than 50% in DUX4 regulated genes, trends of functional improvement, and favourable safety and tolerability in people living with FSHD. Avidity plans to accelerate initiation of registrational cohorts in its Phase 1/2 trial.

FSHD is a rare, hereditary disorder marked by life-long, relentless loss of muscle function, significant pain, fatigue, and progressive disability, for which there are currently no approved therapies. AOC 1020 is the first investigational therapy designed to treat the underlying cause of FSHD.

As of the most recently published 30th April NAV, Avidity represented a 13.4% position.

Rod Wong, Chief Investment Officer at the Investment Manager, said,

"We are delighted to have supported Avidity from its crossover round in 2020 all the way through to now this data, which further validates its antibody oligonucleotide conjugate platform. The approach combines 'the specificity of monoclonal antibodies with the precision of oligonucleotide therapies to hit targets traditionally deemed unreachable.'"
