The Secret Ingredient is... No Gravity? The Latest Spin on Drug Discovery.

 

The future of drug discovery might just involve a healthy dose of space travel. On February 21st, 2024, a California-based company called Varda Space Industries made a splash landing with their W-1 mission capsule. But what made this landing so remarkable wasn't the capsule itself, but its precious cargo: antiviral drugs grown in the microgravity environment of Low Earth Orbit (LEO).

Varda was founded by veterans of SpaceX and Silicon Valley. It is at the forefront of an expanding space industry trend of utilizing the declining cost of spaceflight for commercial ventures.

Their ambitious goal? To transform pharmaceuticals by developing them in the unique, gravity-free environment of space. The rise of reusable rockets and rideshare programs has opened up exciting possibilities for companies like Varda.

Varda believes the absence of gravity offers a unique opportunity to create superior drugs. Gravity can be disruptive during drug development, affecting various processes like crystallization.

“Removing gravity allows us to make medicines you otherwise couldn't on Earth. Gravity is kind of like a parameter. If you put a temperature knob on an oven, you create a whole world of new recipes and new food you can create. Similarly, if you can change gravity, you can also change the chemical process for drug formulations." Quoted Will Bruey the CEO of Varda.

The W-1 mission launched in June 2023 aboard a SpaceX Falcon 9 rocket. Partnering with Rocket Lab's Photon spacecraft, the capsule spent eight months in space successfully producing Ritonavir, an antiviral medication. This first mission marks a significant milestone for Varda, demonstrating the feasibility of in-space drug manufacturing and retrieval. Both Rocket Lab and Varda have hailed this mission as a testament to teamwork and innovation.

The W-1 capsule is currently undergoing analysis at Varda's facilities, while the produced Ritonavir heads to a commercial partner for characterization. Looking ahead, Varda is already gearing up for their second launch this summer, once again utilizing a Photon spacecraft. This mission will not only contribute to advancements in space pharmaceuticals but also generate valuable data for the Air Force and NASA, thanks to a collaborative contract.

Varda's successful mission signifies a new dawn for the pharmaceutical industry. As the cost of space travel continues to decrease, the potential for microgravity-based drug development becomes increasingly real. This exciting development paves the way for a future where new, improved medications might quite literally fall from the sky.
