• Research & Development

Data published in March by researchers at the Mount Sinai School of Medicine found that cannabinoids inhibit TAT induced migration to TAT via cannabinoid 2 receptors (CB2).

Cannabis Science's development of CS-TATI-1 will be targeted to both newly diagnosed and treatment-experienced patients with drug-resistant HIV strains, as well as those intolerant of currently available therapies. Cannabis Science will be pursuing a wide range of NIH based Federal Research Programs such as RO1s, PO1s and SBIRs which exist to support preclinical development of target validation and proof of concept studies. Cannabis Science will be pursing implementation of these studies through collaborations with leading scientific institutions. Cannabis Science will also be pursuing other clinical research collaborations including the AIDS Clinical Trials Groups (ACTG), the Canadian AIDS Trial Network (CATN) and the European AIDS Trial Network (EATN).

Our product is a whole plant extract, formulated for topical administration as a Phase I product, then to be potentially investigated as an oral administration for systemic delivery.

Kaposi Sarcoma
Kaposi Sarcoma (KS) is a form of cancer that develops typically from exposure to the HHV8 virus, a type of Herpes simplex virus. HHV8 can lay dormant in the body and develop when and if the immune system is dramatically weakened. KS arises from the cells that line lymph or blood vessels. KS lesions can occur internally in lymph nodes and visceral organs, externally on various parts of the body or both internally and externally.

Some cancers are classified by where in the body it occurs such as breast cancer, liver cancer or lung cancer. KS is categorized by the population it effects. There are several distinct types of KS:


Epidemic AIDS-Related Kaposi Sarcoma
AIDS-Related Kaposi Sarcoma occurs in HIV positive men who have sex with men in the United States and in people with AIDS, mostly adults, in Africa. The incidence of KS has dropped dramatically since the advent of HIV antiretroviral therapy in the mid 1990’s but is still the predominant cancer experienced by people living with HIV worldwide. KS normally occurs once an HIV-positive persons CD4 count has dropped below 200 CD4 cells per microliter.

In 2007, reports began to emerge of KS occurring in HIV positive gay men with CD4 levels as high as 600 cells per m/L.

This type of KS primarily affects older men in the Mediterranean, Middle Eastern and Eastern European regions and is typically not as severe as endemic or AIDS-related KS. Women can also develop Classic KS but at a lower frequency than men.


Classic (Mediterranean) Kaposi Sarcoma
This type of KS primarily affects older men in the Mediterranean, Middle Eastern and Eastern European regions and is typically not as sevbere as endemic or AIDS-Related KS. Women can also develop Classic KS but at a lower frequency than men.


Endemic (African) Kaposi Sarcoma
Endemic KS occurs in HIV negative me , women and children in Africa. There are two types of endemic KS:

  • African Lymphadenopathic Kaposi Sarcoma occurs mainly in children before puberty in sub-Saharan Africa. It affects the lymph nodes and possibly the skin and is often life-threatening.
  • African Cutaneous Kaposi Sarcoma normally afflicts men under age 50 in tropical regions of Africa. Lesions present primarily on the limbs.

Endemic Kaposi Sarcoma has become the most prevalent form of cancer in men and the second in incidence among women.


Latrogenic (Transplant-Associated) Kaposi Sarcoma
This form of KS occurs in transplant patients with HHV8 who have taken drugs to suppress their immune system in order to decrease the likelihood of the body rejecting the transplanted organ. Latrogenic KS is usually mild and lesions often disappear once the drugs are discontinued.


Cannabis Science will focus the development of Cannabinoid therapies for Epidemic (HIV-related) Kaposi Sarcoma.
