SORTIS Invest Advised KDTB Research on the Fundraising for a New Antibiotic for Tuberculosis

KDTB Research, a drug development start-up developing a new medicine for treatment of Tuberculosis, closed a successful funding round with the assistance of SORTIS Invest. The financing was led by Innovation Capital – a venture capital fund located in Sofia, Bulgaria.

KDTB Research is a company that specializes in developing superior drugs for treatment of Tuberculosis – one of the Top 10 deadliest infectious diseases in the world, with 10,000,000 new cases every year, and a 14% mortality rate (compared less than 1.9% for COVID-19).

The capital was raised to conduct further research of the drug efficacy for CINARIF® – a patented new molecule in the fight against tuberculosis.
