AT WORK
(Jan 18, 2017) - FDA Removes Resolaris' Partial Clinical Hold: Muscular Dystrophy Trials Back on Schedule RDR Staff 
In mid-December, aTyr released data from their Phase 1b/2 trial of resolaris for the treatment
of multiple rare genetically distinct myopathies such as limb-girdle muscular dystrophy 2B
(LGMD2B), and facioscapulohumeral muscular dystrophy (FSHD). While the data looked
promising, the FDA put the trial on partial clinical hold based on a dosing ceiling.
That was then, this is now. Today, the company announced that not only has the FDA has
removed the hold, allowing aTyr to continue trial for resolaris, but the FDA has fast tracked
the orphan drug as well.
The Phase 1b/2 trial was a 12-week, international, open-label, intra-patient, placebo, dose
escalation study administering intravenous infusions of resolaris with dose escalation in
LGMD2B and FSHD adult patients in 2 groups, twice weekly.
 Group A: 4 patients with FSHD received infusions of Resolaris with the highest dosing up
to 1.0 mg/kg biweekly for a period of 4 weeks.
 Group B: 10 patients with LGMD and 4 patients with FSHD received infusions of Resolaris
with the highest dosing up to 3.0 mg/kg biweekly for a period of 4 weeks.
Both groups showed statistically significant results in treatment.
With the Fast Track Designation, the FDA will facilitate and expedite development and
review of resolaris. Through the Fast Track program, a product may be eligible for priority
review at the time of BLA and may be eligible to submit sections of the BLA on a rolling
basis as data become available.

2) Resverlogix Corp (Canada)
Resverlogix Highlights Unique Properties of Apabetalone in Both a Rare Muscular
Dystrophy (FSHD) and Neurodegenerative Eye Disease
Emergence of new potential indications for apabetalone (RVX-208) via third party research
CALGARY , Feb. 13, 2017 /CNW/ - Resverlogix Corp. ("Resverlogix" or the "Company")
(RVX.TO) today highlighted two potentially new indications recently identified by third
party academic research involving its lead drug, apabetalone. The first indication was
published in the Journal of Neuroinflammation which described the inhibition of
bromodomain and extra-terminal (BET) epigenetic readers, including apabetalone (RVX-
208), as having therapeutic potential in degenerative diseases of the eye (retinal). The second
indication was highlighted by research conducted at Saint Louis University , demonstrating
apabetalone mediated modulation of important targets in Facioscapulohumeral Muscular
Dystrophy (FSHD). Both indications are areas of interest and licensing potential for
Resverlogix.
Findings on Facioscapulohumeral Muscular Dystrophy: FSHD is a debilitating disease that
arises from a genetic defect and is one of the most common types of muscular dystrophy
affecting approximately 12 in 100,000 people. This muscle disorder initially affects the
muscles of the face, shoulder blades and upper arms with eventual spread to other muscles of
the body. In research conducted at Saint Louis University and subsequently used in a patent
application, BET inhibitors were shown to inhibit expression of the DUX4 gene, which is
expected to reduce the severity of symptoms in this disease. Apabetalone treatment, when
compared to other BET inhibitors, demonstrated a similar repression of DUX4, however no
transient suppression of MYH2 (a differentiation marker for myotubes) was observed. This
differential effect on the marker of muscle cell differentiation was unique to apabetalone and
demonstrated the distinct properties of this BET inhibitor.
Treatment of FSHD via BET protein inhibition offers a novel therapeutic indication for
apabetalone and this class of compounds.
