Dafra Pharma R&D has been awarded an exclusive licence from the Max Planck Society to develop a drug against leishmaniasis

Max Planck Innovation, the technology transfer agency of the Max Planck Society based in Munich, Germany and Dafra Pharma R&D, a Belgian research company belonging to Dafra Pharma International, signed a license agreement today for the development and commercialisation of a new drug against leishmaniasis.

Leishmaniasis

Leishmaniasis is a so-called ‘neglect ed’ parasitic disease. It occurs in 88 different countries spread over 4 continents and is most frequent among the most vulnerable, poorer populations of East Africa, the Indian subcontinent and South America. In other words, there are some 350 million people living in the \'danger zone\' for this disease. According to WHO figures, around 12 million people are infected with the disease, which is transmitted by the bite of an infected female sandfly. Sandflies are usually infected by animal reservoir hosts, but humans can also pass on some forms.

The disease manifests itself in three ways: cutaneous, mucocutaneous and visceral. Cutaneous leishmaniasis is the most frequently occurring form, entailing wounds (lesions) that remain localised on the skin, developing into ulcers that can lead to severe mutilation and/or leave permanent scarring. By contrast, visceral leishmaniasis (also known as kala azar and black fever) attacks the victim’s organs, causing chronic symptoms characterised by irregular bouts of fever, substantial weight loss, a distended spleen and liver and also anaemia. The visceral form of leishmaniasis is the severest form of the disease, invariably proving fatal if left untreated.


A promising new treatment for leishmaniasis?

Until 10 years ago, there was no really effective treatment for leishmaniasis. Existing therapies, like pentavalent antimonials (antimony) and (liposomal) amphotericin B, have never been optimal and even have serious drawbacks, such as toxicity and neural effects. Moreover, the parasites have developed resistance to these drugs, and treatment is very expensive mainly due to the required parenteral routes of administration. This is problematic since the disease affects poorer people. On top of this, leishmaniasis has recently turned out to be a highly opportunistic infection, affecting vulnerable AIDS and transplant patients, for example.

In 2000, the Max Planck Society announced the pharmaceutical formulation of a chemical called hexadecylphosphocholine as a ground-breaking new therapy for leishmaniasis. It is the first drug against leishmaniasis which, by oral application, can cure this fatal disease. The active substance was discovered by Professor Hansjörg Eibl at the Max Planck Institute for Biophysical Chemistry, working together with Professor Clemens Unger at the University of Göttingen.

After many years of practical application, the spectrum of side-effects is well-known: very common are vomiting, diarrhoea, and increase of liver enzymes. These restrictions for hexadecylphosphocholine in the treatment of leishmaniasis led to a comprehensive re-study of structural variation in alkylphosphocholines. One of the most important representatives of this new class is oleylphosphocholine.

Oleylphosphocholine is particularly active against the parasite that causes leishmaniasis. Administering a pharmaceutical formulation of this compound to affected animals leads to their full recovery. Even better, according to Professor Eibl, the active substance’s safety and lack of side-effects have now also been confirmed by further animal studies. Consequently, further refinement of the substance for its use in humans is an obvious next step. It can be expected that the treatment of leishmaniasis with oleylphosphocholine can completely control, even cure this fatal disease in humans.
 

Cooperation between Dafra Pharma R&D and Max Planck Innovation

The Max Planck Society was founded in 1948, and is the successor organization to the Kaiser Wilhelm Society, which was established in 1911. Max Planck Society has produced no fewer than 17 Nobel Prize winners and its primary goal is to promote research at its own institutes. Conducting research for the future also means serving society by conducting research for mankind. The Max Planck Society’s subsidiary, Max Planck Innovation, passes on the results of its parent’s basic research to industry.

Dafra Pharma R&D was chosen for the continued development and commercialisation of the new product oleylphosphocholine. The goal of the partners’ cooperation is to produce a better, cheaper treatment for leishmaniasis, and Dafra Pharma R&D has been issued an exclusive licence to do just that.

Dafra Pharma R&D belongs to the Dafra Pharma International group, which made its reputation by developing and marketing the latest generation of antimalarial drugs (ACTs) at affordable prices. The company has done a tremendous amount of pioneering work in introducing these ACTs to Africa and has now duly become the market leader on the African continent.

In addition to its commercial strength in Africa, Dafra Pharma International also has a strong R&D subsidiary, and for some years now that company, led by Dr F.H. Jansen, has been focussing on the development of new molecules designed to counter ‘neglected diseases’, including TB (tuberculosis), schistosomiasis (bilharziosis), trypanosomiasis (African sleeping sickness) and toxoplasmosis. At least 1 billion people suffer from one or more of these ‘neglected tropical diseases’ (NTDs), which together claim an estimated 500,000 to 1 million lives every year.
