LCT reports sustained improvement from DIABECELL
LCT reports sustained improvement from DIABECELL NZ
Trial
• Ten patients enrolled in the
Phase II in New Zealand have received DIABECELL® implants
according to schedule
• Patients given 10,000 islet
equivalents/kg showed an average reduction of 76% in
episodes of clinically significant unaware hypoglycaemia
(low blood glucose)
• Improved blood glucose control
shown with reduction in insulin requirements
• Two
patients from the third group of four patients have received
20,000 IEQ/kg with two more to follow during the remainder
of 2010
27 October 2010: Sydney, Australia & Auckland, New Zealand. Living Cell Technologies Limited (ASX: LCT; OTCQX: LVCLY), a global company pioneering the development of cell implants to treat diabetes, today reported continuing positive results from the New Zealand Phase II clinical trial of DIABECELL, with 10 of the 12 insulin-dependent diabetes patients having now received the implants of encapsulated porcine islets.
The first group
of four New Zealand patients received one implant of
DIABECELL at the dose of 10,000 islet equivalents per
kilogram body weight (IEQ/kg).
One patient from this
group has been followed up for 52 weeks and the other three
patients for a minimum of 30 weeks. In all patients in this
group there has been a reduction in the number and severity
of hypoglycaemic events, which are episodes when blood
glucose levels are very low and may lead to loss of
consciousness and convulsions without warning symptoms. The
average decrease in the severity of low blood glucose events
at 24 weeks in this group is a remarkable 64%.
Even more
compelling is the reduction in life-threatening unaware low
blood glucose events, which have dropped by an average of
76%. One patient, who has now been followed up for 52 weeks,
has not had a single unaware event since week five. This has
significantly improved his quality of life and relieved
family stress.
By week 24, patients in the first group
had reduced their insulin dose by an average of 32%. The
daily insulin dose is adjusted according to daily blood
glucose measurements by the patient.
Details of HbA1c
and continuous blood glucose monitoring are blinded to the
clinical team who serve as independent trial officiators.
This information relating to response of blood glucose
control to treatment will be unblinded after one year
follow-up.
These results to date demonstrate the
sustained ability of DIABECELL to ameliorate hypoglycaemic
unawareness and provide a key indicator of benefit to
patients with diabetes. Importantly, there have been no
reported product related adverse events. This continues to
confirm the safety profile of DIABECELL and supports the
long-term patient benefit of the implant.
Prof Bob Elliott, LCT Medical Director said: “I am pleased to see that the initial beneficial results of DIABECELL are being sustained and are having a dramatic positive impact on the lives of implant recipients and their families.”
“Hypoglycaemic unawareness is a dangerous complication
which occurs in about 20% of insulin dependent diabetic
people and is responsible for up to 8% of deaths in this
group. The ability to reduce the likelihood of these
dangerous events is a significant step toward normalising
the lives of our patients.”
The second group of four
New Zealand patients has received a dose of 15,000 IEQ/kg
with no significant adverse events attributed to the
treatment. These patients have now been followed up for at
least 12 weeks. On average to date they show a reduction in
the severity of low blood glucose events of 8% and a
significant reduction in unaware low blood glucose events of
30%.
The fact that the hypoglycaemic episodes have not reduced at a greater rate compared with patients treated at the lower level dose of 10,000 islet equivalents per kilogram body weight (IEQ/kg) provides important information to determine the ideal dose range for patients and is a key component of this trial as the company moves closer to identifying its target product profile.
In the third group of four patients, two have received a higher dose of 20,000 IEQ/kg with no significant adverse events attributed to the treatment. At this time, the follow up period is too short to assess response to treatment.
Dr Ross Macdonald, Chief Executive Officer LCT added: “We expect the dose seeking studies to continue delivering positive results and important information. With consistent benefit in the form of reduction or elimination of hypoglycaemic events, LCT is planning to expand clinical trials of DIABECELL to obtain the necessary pivotal data for the treatment to be approved.”
DIABECELL is LCT’s treatment designed to normalise the lives of people with insulin dependent diabetes. DIABECELL comprises encapsulated porcine insulin-producing cells (islets) that are implanted into the abdomen of patients using a simple laparoscopic procedure, and work by self-regulating and efficiently secreting insulin in the patient’s body. LCT's breakthrough proprietary encapsulation technology means that patients receiving DIABECELL treatment do not require immunosuppression after implantation.
