XTL
Biopharmaceuticals Initiates Phase IIb Clinical Trial of Bicifadine
for the
Treatment of Diabetic Neuropathic Pain
Company
to Hold a Conference Call Tomorrow (Tuesday) at 8:30 am EDT to
Discuss the
Clinical Trial
Valley
Cottage, New York, September 10, 2007 -
XTL
Biopharmaceuticals Ltd. (NASDAQ: XTLB; LSE: XTL; TASE: XTL) today announced
the
initiation of a Phase IIb clinical trial of Bicifadine - a serotonin and
norepinephrine reuptake inhibitor (SNRI) - for the treatment of diabetic
neuropathic pain.
Bicifadine
is being developed for the treatment of diabetic neuropathic pain which
represents a significant unmet medical need in the rapidly growing multi-billion
dollar neuropathic pain market. Bicifadine is a member of the SNRI drug class,
a
proven class in the treatment of diabetic neuropathic pain. Bicifadine’s
efficacy in reducing pain has been clearly demonstrated in over 15 clinical
trials in acute pain, and its favorable safety profile has been established
in
over 3,000 patients. Importantly, Bicifadine has a unique ratio of reuptake
inhibition of serotonin versus norepinephrine, which differentiates it from
other members of the SNRI drug class.
The
Phase
IIb trial that was launched today is aimed at demonstrating the efficacy of
Bicifadine in diabetic neuropathic pain, using a study design that is similar
to
the successful registration trials of Cymbalta®, a member of the SNRI class that
is approved for this indication, and other approved agents for neuropathic
pain.
The
Phase
IIb study is a randomized, double-blind, placebo-controlled study comparing
200mg 3x/day (tid) and 400mg 3x/day (tid) of Bicifadine versus placebo, with
a
1:1:1 randomization between the three arms, in patients with diabetic
neuropathic pain. The Phase IIb study is designed to enroll approximately 330
patients. Approximately 45 clinical centers in the United States, Europe and
India will participate in the study. Following randomization, all patients
will
enter a 2-week titration period to allow them to gradually escalate up to their
target treatment dose. This will be followed by a 12-week steady-state treatment
period at the target treatment dose. The primary endpoint of the study is to
compare the efficacy of each of the two active doses of bicifadine (200mg tid
and 400mg tid) versus placebo in reduction of pain associated with diabetic
neuropathy, at baseline (at the time of randomization) versus week 14 (week
12
of the steady-state phase). Pain will be measured based on a 24-hour pain rating
using the 11-point Pain Intensity Numeric Rating Scale (formerly referred to
as
the LIKERT scale).
The
lead
investigators in the study are Dr. Andrew Boulton, M.D. and Dr. Sherwyn
Schwartz, M.D. Dr. Boulton is Professor of Medicine, Division of Endocrinology,
Diabetes and Metabolism, at the University of Miami and the University of
Manchester, UK. Professor Boulton has been active in clinical research in
diabetic neuropathy over the last 25 years and has published over 250 peer
reviewed articles on the subject. He was co-chair of the committee that
formulated the American Diabetes Association statement on diabetic neuropathy
published in Diabetes Care in 2005. Dr. Schwartz is Chief Executive Officer
and
Chief Medical Officer of DGD Research, Inc. which is the largest diabetes and
endocrinology practice in the United States. Dr. Schwartz has over 20 years
of
clinical research experience in diabetes and diabetic complications, and has
participated in hundreds of clinical trials in the field.
Dr.
Christine Sang, Director of Translational Pain Research at the Brigham and
Women’s Hospital, Harvard Medical School, and Chair of XTL’s Scientific Advisory
Board, commented, “Based on the evidence for the role of SNRI’s in the treatment
of neuropathic pain, I believe that Bicifadine has strong potential to be
successfully developed as a treatment for diabetic neuropathic pain. I am also
encouraged by the drug’s activity observed in previous acute pain studies and
its safety exposure in over 3,000 patients to date.”
Dr.
Andrew Boulton, Co-Lead Investigator in the study, commented, “This study design
is similar to the design of the successful registration trials of duloxetine
(Cymbalta®) in diabetic neuropathic pain and those of other approved agents.
This study is well powered to demonstrate a clinical benefit that is comparable
to the approved agents for this disease. I am happy to be involved in this
important program.”
Dr.
Sherwyn Schwartz, Co-Lead Investigator in the study, commented, “As the head of
the largest diabetes center in the country, I believe that diabetic neuropathic
pain continues to be an area of tremendous unmet medical need, as many patients
do not adequately respond to the limited number of therapies that are available.
I am intrigued by the possibility of having another SNRI with a unique ratio
of
reuptake inhibition of serotonin versus norepinephrine to offer to my patients.”
Ron
Bentsur, XTL’s Chief Executive Officer, commented, “We are very excited to be
initiating this late-stage clinical trial for Bicifadine and are enthusiastic
about the strong support for this trial from many of the top clinical
investigative sites from around the world.”

ABOUT
DIABETIC NEUROPATHIC PAIN
Diabetic
neuropathic pain is a chronic pain condition resulting from damage to nerves
in
patients with diabetes. Diabetic neuropathic pain, which manifests itself
primarily in the feet, can often be debilitating thus preventing patients from
carrying out their normal day-to-day activities. In the United States, it is
estimated that 4.5 million patients with diabetes suffer from diabetic
neuropathic pain. Diabetic neuropathic pain is the largest segment in the
rapidly growing market for neuropathic pain drugs. This market was estimated
at
$1.8 billion in 2005, and is expected to grow to $5.5 billion by 2015. Only
two
oral drugs have been approved to date by the FDA for the treatment of diabetic
neuropathic pain (Eli Lilly’s Cymbalta®, an SNRI, and Pfizer’s
Lyrica®);
however, the response rates to these drugs are limited. Consequently, millions
of patients remain without adequate treatment options and seek new drugs that
could provide better relief for their chronic pain.
ABOUT
THE SNRI DRUG CLASS
Serotonin
and Norepinephrine Reuptake Inhibitors (SNRI’s) are drugs that increase the
levels of serotonin and norepinephrine in the brain, thus blocking pain signals.
SNRI is a proven drug class in diabetic neuropathic pain as well as Major
Depressive Disorder. One SNRI (Eli Lilly’s Cymbalta®) is already approved for
the treatment of diabetic neuropathic pain, while a second SNRI (Wyeth’s
Effexor®) has demonstrated efficacy in treatment of diabetic neuropathic pain in
large, randomized and placebo-controlled studies. Both Cymbalta® and Effexor®
are also approved for depression. A third SNRI (Cypress’ Milnacipran®) recently
demonstrated efficacy in a Phase III trial in a related neuropathic pain
indication (fibromyalgia), providing further evidence of the efficacy of the
SNRI class in neuropathic pain.
ABOUT
BICIFADINE
Bicifadine
is an SNRI which is presently being developed for the treatment of diabetic
neuropathic pain. As a member of the proven SNRI class, Bicifadine is expected
to demonstrate efficacy in the treatment of diabetic neuropathic pain.
Bicifadine has already demonstrated its efficacy as an analgesic in 15 clinical
trials in patients suffering from acute pain, including in two large,
randomized, placebo-controlled Phase III trials. In addition, Bicifadine has
already demonstrated a favourable safety profile, having been evaluated in
more
than 3,000 patients.
Bicifadine
is different from other approved members of the SNRI class in its unique ratio
of inhibition reuptake of serotonin versus norepinephrine (which is weighted
towards norepinephrine reuptake inhibition). This unique ratio is expected
to
translate into a unique response profile of patients to Bicifadine.
As
the
treatment paradigm in neuropathic pain involves switching patients among drugs
(both within the same drug class, as well as among drug classes), in order
to
find the specific drug to which the patient responds best, Bicifadine is
expected to offer a unique alternative to patients who do not adequately respond
to the currently approved drugs. Furthermore, if clinical trials demonstrate
that Bicifadine has an advantage over the currently approved drugs in either
overall efficacy rates, safety profile, or onset of action, it has the potential
to become a first-line treatment for diabetic neuropathic pain.
