Aeovian Pharmaceuticals has collected $55 million to see if it can prove its mTORC1 approach in tuberous sclerosis complex and consider getting into obesity with another mechanism.
The Series B, disclosed Tuesday, will fuel the completion of a Phase 2 of an oral mTORC1 inhibitor in patients with tuberous sclerosis complex (TSC)-related epilepsy, as well as preclinical work in other neurodegenerative diseases. In TSC, the rare genetic disorder leads to non-cancerous tumors in various organs.
Investors include Luma Group, CTI Life Sciences Fund, Foresite Capital, TSC Alliance Endowment Fund, Sofinnova Investments and venBio, among others. The company last disclosed a
$50 million round
led by Hevolution in March 2024.
Aeovian plans to initiate the Phase 2 of AV078 early next year and report data about 18 months later, CEO Allison Hulme told
Endpoints News
in an interview. The trial will enroll in the US, Canada, UK, Europe and Australia, she said.
“Epilepsy still exists in TSC. We have not wiped that out,” TSC Alliance CEO Kari Rosbeck said in a separate interview.
Aeovian’s AV078 is the first clinical-stage drug to have come out of the TSC’s preclinical consortium, Rosbeck said. About a dozen other experimental medicines in the consortium are moving towards clinical development, she said.
With “current treatments, if you go from 50 seizures down to 15, it’s still not ideal, you’re still quite incapacitated. So can you dose higher, get those seizures further down?” said Themasap Khan, co-founder and partner of Luma Group, the co-lead investor in Aeovian’s Series B. “That just got us very, very excited.”
Multiple drugmakers over the years have been interested in mTORC, which is the molecular target of rapamycin, the immunosuppressant that has been around for a quarter of a century.
But pharma companies have run into roadblocks over the years, as many of the candidates have not been selective enough to mTORC1, Hulme said. Companies in the mTORC1 space have included
Novartis
,
Supernus
and Johnson & Johnson. J&J
acquired Anakuria Therapeutics
and its candidate AT-20494 for undisclosed terms in 2022.
By being brain-penetrant and selective to mTORC1, Aeovian expects AV078 to be more effective and less toxic. “We clearly showed in our non-clinical tox programs that we were differentiating from those non-selective mTOR inhibitors like rapamycin and everolimus,” Hulme said.
Everolimus, also known as Novartis’ Afinitor, was the
first
drug to receive approval for TSC patients in 2010, for treating subependymal giant cell astrocytomas, or SEGAs.
While Aeovian’s initial clinical focus is on epilepsy, the nine-employee biotech has broader ambitions for treating TSC.
“Ultimately, we should be able to become the TSC drug of choice,” Hulme said. “We should be able to treat the other manifestations of tuberous sclerosis complex with this particular lead compound,” she said, pointing to SEGAs as an example.
Aeovian also has a peripheral mTORC1 inhibitor, AV505, that could be applied to metabolic diseases and autosomal dominant polycystic kidney disease.
The California biotech is also in the preclinical stages on CD38 enzyme inhibitors.
The CD38 research could lead to potential treatments for Duchenne muscular dystrophy, obesity, MASH and other areas, Hulme said. Verge Genomics has
preclinical
CD38 program for weight maintenance.
“This round has gone up, up and up multiple times, and now [Aeovian] has enough resources to put some capital toward the 38 [program],” Khan said in an interview. “We have to see where that data plays out. They’re pretty quick and dirty experiments we can run for a pretty limited budget, and then if those look good, it could be very exciting in many ways for the company to continue to build that out, but we have to see.”
