The word "Astra" is derived from the Sanskrit root "ast" which means "to throw" or "to cast." According to Hindu mythology, an "Astra" is a weapon that is invoked to accomplish a specific purpose. Immense knowledge and power are necessary to invoke Astra. The Astras were considered to be tremendously powerful and their properties and effects being tuned by the mantras (knowledge) associated with them.

At ASTRA Therapeutics, we are using our knowledge and power to bring anti-pathogen cures wherever they are needed.

Our Journey So Far


Novartis FreeNovation Grant

Natacha and Ashwani were awarded the prestigious Novartis FreeNovation grant. The grant was specifically awarded to support their research in generating high-resolution structural data on tubulin and microtubules derived from Protozoan Pathogens. 


Swiss National Science Foundation Spark Grant

Natacha and Ashwani were awarded the SNF Spark grant to probe their ideas on the role on host microtubule cytoskeleton in the process of pathogen invasion.
