BLU-5937 for Chronic Cough

The Company’s lead drug candidate is BLU-5937, a highly-selective P2X3
antagonist which has the potential to be a best-in-class therapeutic for
refractory chronic cough patients.

Topline data from the Phase 1 study of orally administered BLU-5937,
reported in November 2018, demonstrated that it is safe and
well-tolerated, with a pharmacokinetic profile supporting twice-daily
dosing. At the anticipated therapeutic doses of 50mg – 100mg, BLU-5937
did not cause any loss of taste perception, and only one subject out of
24 (4.2%) reported transient taste alteration. No subject reported total
loss of taste at any dose levels.

The Company anticipates initiating a clinical Phase 2 study in mid-2019.
This will be a dose-escalation, crossover design study to assess the
efficacy, safety and tolerability of BLU-5937 at four doses: 25, 50, 100
and 200mg BID. Approximately fifty patients with refractory unexplained
chronic cough are expected to be enrolled at 12 clinical sites in the
United Kingdom and United States.

Revenues       $ 9     $ 9
Research and development expenses, net         (3,229)       (1,245)
General and administrative expenses         (1,403)       (704)

  • Research and development expenses, net of research tax credits,
    amounted to $3,229,000 for the three-month period ending March 31,
    2019, compared to $1,245,000 for the corresponding period the previous
    year. The increase is primarily attributable to higher expenses
    incurred in relation to the development of BLU-5937.
  • General and administrative expenses amounted to $1,403,000 for the
    three-month period ended March 31, 2019, compared to $704,000 for the
    corresponding period the previous year. The increase is mainly due to
    higher stock-based compensation expense in relation to the Company’s
    stock option plan and deferred share unit plans.
  • Net finance costs amounted to $168,000 for the three-month period
    ended March 31, 2019, compared to net finance income of $97,000 for
    the corresponding period the previous year. The increase in net
    finance costs is primarily attributable to a foreign exchange loss
    that arose from the translation of the Company’s net monetary assets
    denominated in US dollars.

As at March 31, 2019, the Company had available cash, cash equivalents
and short-term investments totalling $45,442,000, compared to
$48,906,000 as at December 31, 2018.

statements and accompanying management’s discussion and analysis for the
three-month period ended March 31, 2019 will be available shortly on

About BLU-5937

BLU-5937, a highly selective P2X3 antagonist – (>1500 fold) for human
P2X3 receptors versus P2X2/3 receptors – has the potential to be a
best-in-class therapeutic for refractory chronic cough patients.

The P2X3 receptor in the cough reflex pathway is a rational target for
treating refractory chronic cough, and it has been validated in multiple
clinical studies. With a modestly-selective P2X3 antagonist therapy for
chronic cough, an adverse effect on taste perception is a well-known and
widely-documented tolerability issue. The Company believes that a highly
selective P2X3 antagonist can reduce coughing in patients with
refractory chronic cough, while maintaining taste function, by not
inhibiting P2X2/3 receptors.

In addition to chronic cough, BLU-5937 may potentially have clinical
benefit in other afferent hypersensitization-related disorders, such as
visceral pain, hypertension, and migraine, among others. BELLUS Health
is exploring how P2X3 activation can contribute to irritation and pain,
and that inhibition of P2X3 receptors may be able to help treat these
afferent hypersensitization-related disorders.
