Kalytera Therapeutics

Leading the Way in CBD Pharmaceuticals

This profile is part of a paid investor education campaign.*


Kalytera Therapeutics, Inc. (TSXV:KALY, OTCQB:KALTF) is a clinical-stage biotechnology company focused on the development of next generation cannabidiol (CBD) pharmaceutical products. The company is pioneering the use of CBD in the prevention and treatment of Graft versus Host Disease (GvHD), a disorder suffered by as much as 50 percent of bone marrow transplant patients. Clinical trials have shown CBD to be potentially efficacious in suppressing the immune-response of the graft cells while simultaneously improving the patient’s ability to fight off infections, both essential for the prevention and treatment of GvHD.

Kalytera is poised to reach a number of key value drivers in 2018 and 2019. The company initiated Phase 2 studies for the evaluation of CBD in the prevention of GvHD in December 2017 and results are expected in Q3 2018. Pending the outcome of those results, Phase 3 studies can begin shortly after with results anticipated for mid-2019.

“We expect to have a very nice inflection point in the company’s market valuation when Phase 2 is complete and we can begin preparing for Phase 3,” said President and CEO Robert Farrell. “At that point we will only be one step from applying for FDA approval as well as approval from other regulatory bodies.”

Kalytera will apply for both Fast Track and Breakthrough Status for the product with Fast Track approval anticipated by the end of 2020. According to research and consulting firm GlobalData, the GvHD market was valued at $295 million across the six major markets in 2013, and is expected to grow to $544 million by 2023.

In an effort to establish itself as a leader in the development of novel CBD pharmaceuticals, Kalytera plans to expand into larger markets addressing a range of important unmet medical needs. Investors can expect near-term catalysts as it expands its product development portfolio to include pantentable CBD pharma compounds for other disease indications.

The company is well managed by an of experienced team of financial and pharmaceutical industry professionals including President and CEO Robert Farrell with 25 years in the life science markets; Dr. Sari Prutchi-Sagiv who has lead scientific operations in multiple cannabis-based drug companies and raised capital via strategic partnerships for early stage technologies; and Director Gary Leong, the former Chief Scientific Officer at Jamieson Laboratories Limited, and the current Chief Scientific Officer of Aphria Inc., a Health Canada licensed producer of medical cannabis products.

  • Orphan Drug Designation granted in the US and Europe
  • No FDA approved therapies for the prevention or treatment of GvHD
  • 2 patents issued covering the use of CBD for the prevention and treatment of GvHD in US
  • Plans to expand the product development portfolio to CBD products for larger commercial marketplaces

Primary Product: CBD Therapeutic for Graft versus Host Disease

Bone marrow transplantation is a lifesaving procedure for patients suffering from blood and bone marrow diseases including leukemia, Hodgkin and Non-Hodgkin lymphoma, multiple myeloma, sickle cell anemia, and thalassemia. About 50 percent of the 20,000+ patients that undergo such procedures each year will develop Graft versus Host Disease. The number of bone marrow transplants is expected to rise annually across the six major global markets.


GvHD is a life-threatening immune system reaction that occurs when the transplanted donor cells (graft) attack the patient’s (host) cells, causing nausea, vomiting, diarrhea and jaundice, and worst of all rashes and lesion on the skin, gastrointestinal (GI) tract, liver, lungs and eyes. The radiation therapy these patients have undergone prior to their transplant operation has already damaged the protective epithelial cells in the skin and GI tract, exposing the patient to the risk of infection. The onset of GvHD dramatically increases the patient’s vulnerability to infection and ultimately death by sepsis.

There are no FDA-approved therapies for the prevention or treatment of GvHD. The current standard of care, generic immuno-suppressants (steroids), have been ineffectual in the prevention and treatment of GvHD. The goal is to suppress the immune response that is causing the GvHD symptoms, however further suppression of the immune system ultimately increase the risk of a life-threatening infection.


Why CBD?

In the face of mounting evidence, the mainstream medical establishment has begun to accept that cannabidiol is safe and has the potential to treat a broad range of medical conditions.


The key to preventing and treating GvHD is the immunosuppression of the graft cells while simultaneously improving the patient’s ability to fight off infections. Clinical trials have shown CBD can do both.

One of CBD’s most medically important attributes is its anti-inflammatory and immunosuppressive properties. Preliminary clinical trials of CBD in the prevention and treatment of GvHD show that CBD suppresses this immune response in the graft cells while promoting the production of occludin, an integral plasma-membrane protein that plays a critical role in the integrity of epithelial cells and their ability to maintain a natural barrier against infection.

The U.S. Patent and Trademark Office (“USPTO”) recently issued the company two patents covering the use of CBD for the treatment of GvHD. This grants Kalytera exclusive worldwide rights to this issued patent. The issuance of the 2nd patent in May 2018 completes the final step in the application process and provides patent coverage to the company for the use of CBD for the treatment of GvHD through May 2034 under the Exclusive License Agreement with Mor.

Kalytera’s GvHD Program

Kalytera acquired its GvHD Program from Israeli-based Talent Biotechs in early 2017 based on the stellar results of Talents’ four Phase 2a clinical studies in the prevention and treatment of GvHD using CBD. The studies were conducted under the scientific leadership of Dr. Moshe Yeshurun, whose primary field of research is GvHD following allogeneic hematopoietic cell transplantation. Dr. Yeshurun began researching the use of CBD for the prevention of GvHD following anecdotal evidence of symptom relief from patients who used marijuana.

Dr. Yeshurun is now Kalytera’s Chief Medical Officer and the Head of the Bone Marrow Transplantation Department at the Rabin Medical Centre in Tel Aviv.

The results of these four clinical studies were published in the Biology of Blood and Marrow Transplantation.

Phase 2a Clinical Study Highlights

  • No patients developed acute GvHD while being treated with CBD
  • The risk of developing acute GvHD by day 100 was decreased
  • Among those that did develop GvHD after HCT, the time to onset was significantly longer (60 days in the CBD group versus 20 days in the historical control group)
  • Patients treated with CBD had fewer skin and gastrointestinal issues compared to the control group
  • CBD treatment was safe and well tolerated


These preliminary results support the continued investigation of CBD for the prevention and treatment of GvHD. Both the US FDA and the European Medicines Evaluation Agency (EMEA) have granted the product an Orphan Drug Designation. The FDA has encouraged Breakthrough Therapy and Fast Track Designations, which have the potential to accelerate the approval process.

Kalytera’s Phase 2 GvHD Prevention Study

Kalytera’s Phase 2 study currently underway is evaluating the pharmacokinetic and safety profile of multiple doses of CBD for the prevention of GvHD in 36 patients who have undergone bone marrow transplantation. The study is taking place at two major medical centers in Israel. The clinical study team is led by Dr. Daniel Couriel, Director of the Bone Marrow Transplant Program at the University of Utah Health Sciences, School of Medicine.

Kalytera expects to bring results to market in September 2018.
