A Mission to Save Lives

Spero Therapeutics is dedicated to delivering differentiated medicines to help patients suffering from serious rare orphan diseases and life threatening infections. Commitment to responsible use, stewardship & stability is what drives us.

Our Vision

Spero was founded to address the serious infections and the growing global threat of antibiotic resistance through innovative therapeutic approaches. Our ability to provide effective therapies today will have long-term impacts on patients’ lives.

Our Values

We’ve built an organization on foundations of stability, momentum and commitment to excellence. Spero’s future hinges on the success + proper stewardship of our current arsenal, as well as shaping the conversation to educate the public on the ability of these drugs to keep people out of the hospital.

Logos

It’s important to maintain proper spacing around the logo to avoid overcrowding. The use of whitespace keeps the brand feeling clean and modern. Try to make sure that there are no competing elements, text or other objects that overlap with the logo to give it the presence it deserves.

Typography

Trebuchet is the alternate font to be used in place of Space Grotesk on internal communications or email where custom fonts are not supported.
