Kamada Announces Top-line Results of Phase 2 Trial of Alpha-1 Antitrypsin in Newly Diagnosed Type-1 Diabetes PatientsNov. 1, 2017
Rehovot, Israel, November 1, 2017 – Kamada Ltd. (NASDAQ & TASE: KMDA), a plasma-derived
protein therapeutics company focused on orphan indications, today announced top-line
results from the Company’s Phase 2 trial of Alpha-1 Antitrypsin (AAT) in newly diagnosed type-
1 diabetes (T1D) patients. The study included 70 patients ranging from 8 to 25 years old. While in
the overall study population no significant treatment effect was observed, in the pre-determined subgroup of patients between the ages of 12 and 18 years old, a trend toward better efficacy was demonstrated in the high dose arm of AAT (120 mg/kg) represented in terms of beta-cell function
preservation, lower average of total daily insulin usage and a better glycemic control measured by
lower average HbA1c. Details about this study are available at
“Given this study was not powered to show efficacy, the results are very encouraging,” said Peter Gottlieb, M.D., Professor of Pediatric and Medicine, Barbara Davis Center for Diabetes, University of Colorado School of Medicine and a leading member in TrialNet, an NIH-sponsored network of institutions and researchers dedicated to the prevention of type-1 diabetes. “These findings suggest that administration of AAT could be an effective treatment option for newly diagnosed T1D patients who are 12-18 years old. The results of this subgroup are intriguing and warrant further studies in a larger population. Subgroup segmentation by age is common in this complicated disease, and the fact that we see the same positive trend in this age group for all three measures – C-peptide, daily insulin requirement, and HbA1C – suggest that the results are consistent and could be promising.”
This double-blind, placebo-controlled, multi-center Phase 2 clinical trial was designed to evaluate the efficacy and safety of AAT IV in halting disease progression in pediatric and young adult patients newly diagnosed with T1D. Seventy patients, ranging in age from 8-25 years old, and recruited within 100 days of diagnosis of T1D, were randomized to three treatment groups in a 1:1:1 ratio; placebo and two doses of AAT, 60 mg/kg or 120 mg/kg. Study duration was 56 weeks and included three treatment periods. During the first 12 weeks, a once-weekly treatment was given, followed by 8 weeks of treatment given every two weeks, then a follow-up period of 26 weeks, followed by a once-weekly treatment given for 6 weeks, and a final 4-week follow-up period. Study endpoints included beta cell function assessment as measured by change in C-peptide parameters, glycemic control represented by HbA1C levels and insulin daily dose.
The key results for the 12-18-year-old patient subgroup treated include:
- Better preservation of beta-cell function, demonstrated as a smaller decline of the average (±SEM) Area Under the Curve (AUC) of stimulated (MMTT) C-peptide secretion over time (-0.18 ± 0.15nmol/L for AAT 120 mg/kg, -0.47 ±0.13 nmol/L for 60 mg/kg, and -0.34 ±0.10nmol/L for the placebo group; p =0.543), suggesting a slower decline in pancreatic function for the 120 mg/kg treatment arm. Similar differences were noted for Cmax (defined as maximum or peak serum concentration).
- Lower average HbA1c (AAT 120 mg/kg: 6.66±0.32%, AAT 60 mg/kg: 7.85±0.45%, placebo: 8.29±0.52%, p=0.052, in addition the p-value of the comparison between AAT 120 mg/kg and placebo was p=0.048) and a higher percentage of patients who achieved the clinically meaningful target of HbA1c ≤7% (AAT 120 mg/kg: 70%, AAT 60 mg/kg: 29%, placebo: 25%, p=0.073).
- In a post-hoc analysis of insulin daily dose intake, a beneficial favorable effect trend was found in the AAT 120 mg/kg treatment group versus placebo, p=0.086.
Kamada’s AAT IV demonstrated a very good safety profile in T1D pediatric and young adult
patients treated in the Phase 2 study, similar to that observed with GLASSIA® for the treatment
of Alpha-1 Antitrypsin Deficiency. There were no differences seen in safety parameters
(treatment emergent adverse events, serious adverse events, etc.) between the placebo and two
treatment arms (60 mg/kg and 120 mg/kg).
“Based on these results, it seems that treatment with AAT in a pediatric population with new-onset
type-1 diabetes in increasing doses up to 120 mg/kg is safe,” said Mariana Rachmiel, M.D.,
Head of Pediatric Endocrinology Unit, Assaf Harofeh Medical Center, Tzrifin, Israel. “While the
study was not powered for efficacy, for the age 12-18-year group, there was significantly better
glycemic control and possible signs of beta-cell function preservation. This trend was not shown
in the group younger than 12 years. Thus, larger studies are required. Importantly, the same trend
was observed in all three key parameters, including C-Peptide AUC, insulin dose, and HbA1C.”
“T1D is a progressive disease where the pancreatic beta cells, in charge of insulin secretion
undergo an autoimmune attack which eventually destroys the pancreatic capability of insulin
production and secretion leading to complete external insulin dependence. Halting disease
progression and maintaining the pancreatic ability to produce insulin could reduce diabetic
complications resulting from poor glycemic control, such as cardiovascular disease, renal failure
and other related impediments.”
Current treatment of T1D patients depends on lifelong external insulin replacement by injections.
Despite insulin replacement, there are still a great proportion of patients unable to achieve adequate glycemic control, resulting in fluctuations of high or dangerously low glucose levels, defined as poor glycemic control.
AAT has been shown to have immunomodulatory properties, including downregulation of proinflammatory responses, increase in anti-inflammatory cytokine release (e.g. IL-10 and IL-1Ra), promotion of regulatory T cells (Tregs) differentiation, and tissue protective properties. This anti-inflammatory activity may attenuate the immune system attack on the pancreatic beta cells, thereby enabling prolonged beta cells function which, in turn, may mitigate the disease progression.
Amir London, Chief Executive Officer of Kamada, stated, “We are encouraged by the positive results from this Phase 2 study, which further validate the strong signal we have seen in our previous Phase 1/2 study and its extension. We believe that our intravenous AAT can be an innovative breakthrough treatment for newly diagnosed type-1 diabetes patients, an area of significant unmet medical need. We believe that the progress we have made with the results of this study demonstrates the significant medical and business opportunity of this product. Once the full data are available, we will evaluate the collective results in order to determine the appropriate next steps forward.”
Kamada Ltd. is focused on plasma-derived protein therapeutics for orphan indications, and has a
commercial product portfolio and a robust late-stage product pipeline. The Company uses its
proprietary platform technology and know-how for the extraction and purification of proteins from
human plasma to produce Alpha-1 Antitrypsin (AAT) in a highly-purified, liquid form, as well as
other plasma-derived Immune globulins. AAT is a protein derived from human plasma with
known and newly-discovered therapeutic roles given its immunomodulatory, anti-inflammatory,
tissue-protective and antimicrobial properties. The Company’s flagship product is GLASSIA®,
the first liquid, ready-to-use, intravenous plasma-derived AAT product approved by the U.S. Food
and Drug Administration. Kamada markets GLASSIA® in the U.S. through a strategic partnership
with Baxalta (now part of Shire plc) and in other counties through local distributors. In addition
to GLASSIA®, Kamada has a product line of seven other pharmaceutical products administered
by injection or infusion, that are marketed through distributors in more than 15 countries, including
Israel, Russia, Brazil, India and other countries in Latin America and Asia. Kamada has five late-stage plasma-derived protein products in development, including an inhaled formulation of AAT
for the treatment of AAT deficiency. In addition, Kamada's intravenous AAT is in development
for other indications, such as type-1 diabetes, GvHD and prevention of lung transplant rejection.
Kamada's rabies immune globulin (Human) product received FDA approval for Post-Exposure
Prophylaxis against rabies infection in August 2017. Kamada also leverages its expertise and
presence in the plasma-derived protein therapeutics market by distributing more than 10
complementary products in Israel that are manufactured by third parties.
