QLT Announces Oral Retinoid Program Clinical and Regulatory Update, and Review of Strategic Alternatives
November 20 2013 - 4:01PM
Plans for Phase IIa Proof-of-Concept
Trial for QLT091001 in Impaired Dark Adaptation
Company to Provide Guidance on
Pivotal Studies in Orphan Indications Before the End of Q1 2014
QLT Inc. (Nasdaq:QLTI) (TSX:QLT) ("QLT" or the "Company") today
announced a clinical and regulatory update related to its synthetic
oral retinoid program, as well as the initiation of a review of
strategic alternatives. For the review, the Board of Directors has
engaged Credit Suisse to act as financial advisor.
QLT announced that, following meetings with the U.S. Food and
Drug Administration (FDA) and the European Medicines Agency (EMA),
the Company believes that it is close to finalizing a pivotal trial
protocol for QLT091001 for the treatment of inherited retinal
disease such as Leber Congenital Amaurosis (LCA) and Retinitis
Pigmentosa (RP) due to mutations in the LRAT and RPE65 genes, both
orphan indications. The Company expects to provide final guidance
on its development plans in these indications before the end of the
first quarter of 2014 after final feedback from the European
regulatory agency. Additionally, QLT has initiated recruitment of
subjects for a Phase IIa proof-of-concept trial of its drug
candidate, QLT091001, in adult subjects with Impaired Dark
Adaptation (IDA), a condition that results in decreased ability to
recover visual sensitivity in the dark after exposure to bright
lights. The Company also announced the launch of a compassionate
use program for QLT091001 in LCA and RP, as well as plans for a
patient registry and an update on its retreatment study in these
indications.
"While we undertake a broad review of strategic options for QLT
with Credit Suisse, we will continue to focus our resources and
efforts on our promising synthetic oral retinoid programs," said
Mr. Jason M. Aryeh, Chairman of the Board. "We are excited with the
progress QLT has made with the program this past year and look
forward to a productive next few months as we prepare this
important therapy for a pivotal trial."
QLT091001 Clinical and Regulatory Update in
Detail
- Pivotal trial guidance in LCA and RP. With
regard to the orphan drug program for the treatment of LCA and RP
due to inherited mutations in the LRAT and RPE65 genes, over the
course of 2013, the Company has met with the FDA and the EMA,
including a recent end-of-Phase II meeting with the FDA, to discuss
proposed pivotal trial design, protocol requirements and
development plans. The Company plans to finalize its communications
with the EMA in the coming months in connection with the pivotal
trial design, with the goal of having the protocol conform to both
U.S. and EU guidance, after which the Company expects to provide
final guidance on the program. QLT believes that it has made
significant progress on multiple fronts with regards to its orphan
oral retinoid program, and will be pivotal trial ready in the first
half of 2014.
- Phase IIa proof-of-concept trial of QLT091001.
The Company has initiated recruitment of subjects for enrollment
into the newly announced Phase IIa proof-of-concept trial of
QLT091001 in adults with IDA. The Company's goal is to initiate
dosing subjects in the trial by the first quarter of 2014.
See "About the IDA Proof-of-Concept Trial" below for details.
- Compassionate use program. Following requests
from physicians and patients, the Company has begun a compassionate
use program for QLT091001 on a named-patient basis. Under the
compassionate use program, QLT091001 may be made available to
patients who participated in the Company's completed Phase Ib
clinical trial of QLT091001 for the treatment of LCA and
RP. The program commenced in Ireland and participation for
other patients will be determined on a case-by-case basis in
accordance with applicable regulatory laws. Compassionate use
programs provide experimental therapeutics to patients with serious
or life-threatening diseases that cannot be treated satisfactorily
with authorized therapies prior to final FDA, EMA or other
applicable regulatory approval.
- Patient registry. Given the ultra-orphan
nature of LCA and RP due to inherited mutations in the LRAT and
RPE65 genes, the Company is in the process of establishing a
central patient registry to identify and characterize patient
status and then follow disease progression to track the natural
history of the disease. The Company plans to launch the
patient registry in conjunction with the advancement of the orphan
program into pivotal trials.
- LCA and RP retreatment study. Dosing in
the Company's retreatment study in LCA and RP subjects is now
completed and follow-up of subjects is ongoing. This study was
initiated in early 2012 to provide retreatment for the subjects
treated in the initial Phase Ib study, in order to examine the
safety, efficacy and tolerability of repeat dosing cycles of
QLT091001 administered over seven days. The Company expects to
complete its preliminary analysis of the data in the first quarter
of 2014.
About the IDA Proof-of-Concept Trial
The Phase IIa proof-of-concept trial of QLT091001 is a
randomized, multi-center, parallel-group, placebo-controlled study
in adult subjects with IDA. Subjects (age 60 or older) with
IDA, or impaired low luminance low contrast best corrected visual
acuity ("LLLC BCVA") in at least one eye and having no known
ophthalmic pathologies to explain their condition other than early
age-related macular degeneration (AMD) will be enrolled at sites in
the U.S. Subjects will be randomized to receive placebo or one
of two different doses (10 or 40 mg/m2) of QLT091001 once per week
for three consecutive weeks with one additional dose the day after
the third dose. The trial is designed to evaluate the safety
profile and effects of QLT091001 on impaired dark adaptation time,
glare recovery time and LLLC BCVA.
About Impaired Dark Adaptation
Impaired Dark Adaptation (IDA) is a condition that results in
decreased ability of the eye to recover visual sensitivity in the
dark following exposure to bright lights (photobleaching) that gets
worse with age. Profoundly impaired dark adaptation is
commonly associated with inherited retinal degenerations. More
recently, mild to moderate impaired dark adaptation has been
associated with AMD and is proportionate to the severity of the
disease. IDA (and/or impaired low luminance vision) may occur due
to age-related inefficiencies in the retinoid cycle which results
in slower regeneration of the light sensing pigment 11-cis-retinal
in the eye and increased levels of free unbound opsin that lead to
delayed dark adaptation and reduced retinal sensitivity.
Ultimately, these factors impair vision in low light or dark
environments. The kinetics of the rod function have also been
reported to be age-related, with the rod-mediated portion of the
dark adaptation function significantly slower in older patients
with normal retinal function than in younger adults. This
rod-mediated dark adaptation time is further slowed down in
patients with early signs of AMD but with good visual acuity.
IDA in this population causes symptomatic difficulties for
functioning in dim light, especially after exposure to bright
ambient light, and can hamper daily living activities such as
driving, mobility, and workplace tasks. Impaired mobility, in
the form of falling, is one of the most common problems of old
age. IDA is not a disease but a condition that can arise as a
result of a number of pathologic or physiologic
factors. Improving this condition has the potential to not
only improve a subject's quality of life but also delay the
development of degenerative retinal conditions with more severe
visual outcomes.
