Maze Therapeutics has
submitted its pitch
for an initial public offering after disclosing a
$115 million Series D,
forging a neuroscience spinoff and running into a dealmaking hurdle with the FTC.
The Bay Area startup revealed its plans Tuesday night to trade on the Nasdaq as
$MAZE
. It has yet to disclose how much it could seek in the proposed offering.
The startup’s IPO pitch follows a relatively dismal multiyear stretch for biopharma public debuts.
Making its IPO desires known in the lead-up to next week’s annual JP Morgan Healthcare Conference will likely drive attention and be the center of conversations as industry insiders hope for more dealmaking and a more bustling public market.
The 121-employee Maze had $149 million in cash and equivalents at the end of September, according to its prospectus.
Third Rock Ventures, which launched Maze in 2019, is its biggest stockholder at 20%. ARCH owns nearly 12%, Matrix Capital holds about 7%, and Foresite and GV each have nearly 7% as well, according to the IPO paperwork.
Its Nasdaq debut would arrive about eight months after
Shionogi signed a deal for
Maze’s Pompe disease asset, which is ready for Phase 2. The Japan-based partner is paying $150 million upfront and an undisclosed amount in biobucks for the small molecule.
It was a quick turnaround for Maze, which was left blindsided by
Sanofi’s decision to pull out of a licensing pact
for the drug in late 2023 in reaction to scrutiny from the Federal Trade Commission, which had said it would move to block the deal.
After the Sanofi deal ended, Maze received “a lot of inbound interest,” Maze CEO Jason Coloma
told
Endpoints News
on the sidelines of JPM last January. Coloma said Maze would “have a better sort of guidance” on its next financing steps, including a potential IPO, once it inked a deal with a new Pompe partner.
Beyond Pompe, the biotech is testing an oral small molecule, dubbed MZE829, as a potential treatment for APOL1 kidney disease. It entered Phase 2 in November, with data slated for the first quarter of 2026. Another small molecule, codenamed MZE782 for chronic kidney disease, entered Phase 1 in September and will have initial data in the second half of this year.
Maze spent $61 million on research and development through the first nine months of 2024, only about $3.5 million more than the same period in 2023, according to its S-1 filing.
The biotech recently shipped its UNC13A-directed antisense oligonucleotide to Trace Neuroscience, which
emerged
with $101 million in November to take on amyotrophic lateral sclerosis.
The biotech has had mixed success with joint ventures in the past. Its ophthalmology-focused partner Broadwing Bio has been quiet in recent years, and its cardiovascular-centered JV with BridgeBio, named Contour Therapeutics, has since been unwound, Coloma
previously told Endpoints
.
Maze’s founders include Verve Therapeutics CEO Sek Kathiresan, the Whitehead Institute’s Jonathan Weissman, Stanford’s Aaron Gitler, Harvard Medical School’s Stephen Elledge, and the Broad Institute’s Mark Daly.
