Gene therapy player Affinia aims to go public, hoping to raise big money in effort to remake AAVs

Rick Modi, Affinia Therapeutics CEO (Affinia)

Nine months af­ter Affinia Ther­a­peu­tics raised $110 mil­lion in a Se­ries B, the biotech has set its eyes on the Nas­daq.

The MA-based pre­clin­i­cal gene ther­a­py biotech, which got $60 mil­lion in start­up cap­i­tal from New En­ter­prise As­so­ci­ates, F-Prime and At­las in 2019, filed an S-1 with the SEC on Tues­day, an­nounc­ing ini­tial plans to go pub­lic and pen­cil­ing in a $100 mil­lion raise. Affinia plans to list un­der the tick­er $AF­TX.

Affinia, found­ed back in 2019 by AveX­is vet­er­ans Sean Nolan and Rick Mo­di and an End­points 11 win­ner last year, has been fo­cused on try­ing to solve the lim­i­ta­tions of AAV gene ther­a­py, as high­light­ed by the safe­ty scares and set­backs of the last two years.

Its three sci­en­tif­ic co-founders in­clude Luk Van­den­berghe, who is an as­so­ciate pro­fes­sor at Har­vard Med and di­rec­tor of the Grous­beck Gene Ther­a­py Cen­ter at Mass­a­chu­setts Eye and Ear In­fir­mary in Boston — and is cred­it­ed as a co-in­ven­tor of the more com­mon­ly-used AAV9.

In terms of cur­rent fi­nan­cial stake in the com­pa­ny, NEA man­ag­ing part­ner Ed Math­ers — on Affinia’s board of di­rec­tors — is the largest share­hold­er, own­ing over 11.8 mil­lion shares and equiv­a­lent to 20.5% of the com­pa­ny. Oth­er big share­hold­ers cur­rent­ly in­clude At­las Ven­ture with just shy of 7.5 mil­lion shares, or 13% of Affinia; F-Prime with al­most a 10% stake and 5.7 mil­lion shares; and Lon­za Hous­ton with 4.9 mil­lion shares and an 8.6% stake.

CEO Rick Mo­di has a 1.4% stake with over 800,000 shares, and Van­den­berghe has 1.5 mil­lion shares, or a 2.7% stake.

While the biotech has al­ready raked in over $200 mil­lion in deals and pri­vate fi­nanc­ings, Affinia wants to use what­ev­er mon­ey it rais­es in an IPO to push to­wards clin­i­cal tri­als, pipeline ex­pan­sion and man­u­fac­tur­ing — al­though no spe­cif­ic dol­lar amounts for those ob­jec­tives were list­ed. The mon­ey should fund op­er­a­tions through 2024, it said. Its lead can­di­date, AF­TX-001, is be­ing de­vel­oped for the treat­ment of metachro­mat­ic leukody­s­tro­phy, a rare ge­net­ic dis­or­der that leads to fat buildup in the body. Its sec­ond can­di­date, AF­TX-002, is in de­vel­op­ment to treat brain metas­tases sec­ondary to HER2+ breast can­cer.

Affinia ex­pects to file INDs on the two can­di­dates in 2023 — the first can­di­date in the first half of the year, and the oth­er can­di­date in the sec­ond half of 2023.

But those aren’t the on­ly things Affinia is work­ing on: They al­so have a sub­stan­tial deal with Ver­tex that Affinia signed in 2020. The S-1 gave fur­ther de­tails on the deal, show­ing it could net Affinia up to $4.7 bil­lion to en­gi­neer cap­sids for use in pro­grams for Duchenne mus­cu­lar dy­s­tro­phy (DMD), my­oton­ic dy­s­tro­phy 1 (DM1) and cys­tic fi­bro­sis (CF).

Their Staying Power Lies in their Patient-Centricity

Decentralized clinical trials (DCTs) were traditionally utilized in an isolated fashion prior to the COVID-19 pandemic. To continue their research within the constraints of the pandemic, sponsors and clinical investigators pivoted to a decentralized model out of necessity. At the onset, regulatory agencies offered some guidance on the digital approaches that are acceptable to ensure DCT approaches are applied in a way that maintains patient safety, as well as data quality and integrity.

It’s big days for biology.

The pandemic has seen a series of very public scientific breakthroughs: mRNA vaccine, Covid antibodies, CRISPR as therapy. The minds behind these advancements have graced magazine covers and received prestigious awards.

But the last two years have also, far more quietly, seen a series of new experiments in how to fund the next generation of scientific breakthroughs.

Since March 2020, investors, academics, a significant number of Silicon Valley types, at least one Russian billionaire and two crypto billionaires and, most recently, a few West Coast universities have launched a series of grant programs, institutes, NGOs and companies hoping to change how life science research is done. Though unaffiliated and varying greatly in both size and form, they have broadly promised to evade bureaucracy and misaligned incentives and advance both basic and not-so-basic research in ways they say can’t be done in either conventional academia or profit-focused biotech.

The FDA this week announced further changes to revamp its structure, this time with alterations to its Office of the Chief Scientist that were agreed to by HHS late last month.

The FDA’s OCS has decided to shift its technology transfer program from the Office of Regulatory Science and Innovation to the OCS Immediate Office to further enhance the effectiveness of the agency’s outside partnership programs.

After a busy 2021 brought Blueprint Medicines its fourth FDA approval, the company is kicking off the new year with plans to shake up its C-suite.

Jeff Albers, Blueprint’s CEO for the past eight years, will be stepping down April 4 and transitioning to the executive chairman position, the biotech announced Wednesday morning. He will be replaced by COO Kate Haviland, who moves into both the chief executive and president roles. Christina Rossi also nabs a promotion from chief commercial officer to COO.

Catalent CEO John Chiminski (Catalent)

If there was one defining theme at Catalent in recent years, it was expansion, as the CDMO upped its operations all over the world, from Baltimore to Japan. It did so under longtime CEO John Chiminski, who has led the Somerset, NJ-based company for 12 years, topped by 2 years of the pandemic. This year will be the last in the C-suite for Chiminski, however, as the company announced plans for a passing of the torch this summer.

As the CEO of RNA editing startup Korro Bio, Ram Aiyar often gets the same question.

‘I get always asked, you know, if you can fix DNA, why bother with RNA?’ he told Endpoints News. ‘And it’s like asking, which child do you prefer — your older one or your younger one?’

But investors are appreciating the difference. More than a year after closing its Series A just shy of the megaround mark, Korro Bio is back in the spotlight with $116 million in fresh cash and a lead candidate — targeting alpha-1 antitrypsin deficiency, or AATD.

Ray Tabibiazar, SalioGen CEO

Roughly 10 months ago, a fledgling biotech emerged from stealth with a modest Series A and a big promise looking to develop gene therapy 3.0. The promise inched closer to reality Wednesday as investors have now hopped on board thanks to a new, nine-figure round.

SalioGen Therapeutics closed its $115 million Series B, the company announced Wednesday morning, aiming to push forward its ‘gene coding’ platform and growing preclinical pipeline. The biotech, which focuses on activating dormant mammalian enzymes to edit genes in vivo, secured the new raise after fleshing out some of the technologies’ applications, CEO Ray Tabibiazar told Endpoints News.

For anyone who’s been following how the US government has been allocating and shipping supplies of its Covid-19 treatments over the past year, the news has shifted so many times that it can be difficult to keep track of what’s still being shipped and where.

More change is coming this week too, as HHS has now decided to re-start shipments of both Eli Lilly (bamlanivimab plus etesevimab) and Regeneron (casirivimab plus imdevimab) monoclonal antibody products after a short pause because neither product works against the new variant Omicron. Lilly’s combo also was halted last June due to the presence of other variants.

Kicking off 2022, hundreds of pharmaceuticals, including some blockbusters, saw their list prices rise by about 5% on average. But overall, net drug prices (cost after rebates) declined for the fourth year in a row, potentially complicating already stalled drug price reform efforts.

Among the drugs seeing new increases as of Jan. 1 are Gilead’s bevy of blockbuster HIV drugs.

Biktarvy, which pulled in more than $7 billion in worldwide sales in 2020, saw a 4.8% price increase in 2021, and now, another 5.6% increase in 2022, according to a new report from the nonprofit 46brooklyn Research.
