Kamada Announces FDA Acceptance of Inhaled AAT Program

Kamada Ltd. recently announced receipt of a letter from the US FDA stating the company has satisfactorily addressed the concerns and questions regarding its Inhaled Alpha-1-Antitrypsin (Inhaled AAT) program for the treatment of Alpha-1 Antitrypsin Deficiency (AATD), previously communicated by the agency.

This most recent response from the FDA in connection with the development plan for Inhaled AAT follows positive scientific advice received in July 2018 from the Committee for Medicinal Products for Human Use of the European Medicines Agency (EMA) in Europe. Kamada intends to conduct a unified global pivotal Phase 3 clinical trial in the US under an Investigational New Drug (IND) application and in Europe under a Clinical Trial Authorization (CTA) in order to submit marketing applications for regulatory approval in both regions. The company expects to initiate the Phase 3 study during the second half of 2019, subject to a successful completion of a Human Factor Study (HFS), to be initiated during the current quarter. The HFS is required to support the combination product, consisting of Kamada’s AAT for inhalation and the investigational eFlow nebulizer system of PARI Pharma GmbH.

The Phase 3 study protocol was designed to test the safety and efficacy of the company’s inhaled AAT product in patients with AATD, and is meeting the requirements provided by the FDA and EMA. The protocol includes the enrollment of up to 250 subjects who will be randomized 1:1 to receive either Inhaled AAT at a dose of 80 mg once daily, or placebo, during 2 years of treatment. The primary endpoint will be lung function measured by FEV1, and secondary endpoints will include lung density changes measured by CT densitometry, as well as other parameters of disease severity.

“We are extremely pleased to receive this feedback from the FDA regarding our Inhaled AAT for the treatment of AATD,” said Amir London, Kamada’s Chief Executive Officer. “We expect to initiate the trial in the second half of 2019, subject to successfully completing the required human factor study. The current global intravascular AAT market is estimated at more than $1 billion annually, and is growing at approximately 6%-8% each year. We believe that our Inhaled AAT, if approved, could capture a significant share of this growing market due to the ability of our treatment to directly reach the lungs, as well as its enhanced convenience that would improve the quality of life for patients. We are encouraged by the strong support we continue to receive from the patient population and leading AATD physicians.”

Kamada Ltd. is focused on plasma-derived protein therapeutics for orphan indications, and has a commercial product portfolio and a 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 US FDA. Kamada markets GLASSIA in the US through a strategic partnership with Takeda Pharmaceuticals Company Limited and in other counties through local distributors. Kamada’s second leading product is KamRAB, a rabies immune globulin (Human) for Post-Exposure Prophylaxis against rabies infection. KamRAB is FDA approved and is being marketed in the US under the brand name KEDRAB and through a strategic partnership with Kedrion S.p.A. In addition to GLASSIA and KEDRAB, Kamada has a product line of four other plasma-derived 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 late-stage products in development, including an inhaled formulation of AAT for the treatment of AAT deficiency, and in addition, its intravenous AAT is in development for other indications, such as GvHD, prevention of lung transplant rejection and type-1 diabetes. Kamada also leverages its expertise and presence in the plasma-derived protein therapeutics market by distributing more than 20 complementary products in Israel that are manufactured by third parties.
