Isomorphic Labs' reported valuation raises the stakes for AI drug discovery

  • STAT's AI Prognosis column asks what Isomorphic Labs' very high valuation says about AI's role in drug development.
  • Separate reports describe early talks to raise new funds at a valuation of at least $40 billion, shortly after a roughly $2.1 billion round in May 2026; no financing has closed.
  • The column also touches on the debate over AI and the cost of care.
💡 Points

A valuation at this level prices in platform optionality, not pipeline: Isomorphic has no disclosed clinical-stage proof yet, so investors are paying for the possibility that structure-prediction AI compresses the road to a first candidate. For the rest of the sector, it raises the bar for what AI-native biotechs must show clinically, and it will pull partnering money toward the leaders. Treat the figure as talks, not a closed deal.

Forbion closes $2.6B, its largest fundraise and among Europe's biggest in years

  • STAT reports European venture firm Forbion has raised $2.6 billion, its largest fundraise to date.
  • It is described as one of the largest in the region in recent years; fund structure and allocation were not visible in the public lede.
💡 Points

A raise this size from a specialist investor says LPs still back biotech formation despite a choppy funding climate, and it gives European startups a deeper home-market option. The things to watch are the split between early-stage company creation and later rounds, and whether it pulls US-bound founders toward European listings.

Caribou Biosciences winds down after failing to fund late-stage CAR-T trial

  • STAT reports the Doudna co-founded company is shutting down after failing to raise the money needed for a late-stage trial of its off-the-shelf CAR-T therapy for lymphoma.
  • Other coverage describes the company stopping development of its two clinical cell therapy candidates and cutting most staff while exploring a merger or sale.
  • Only the public STAT+ summary was available, so details beyond that are unverified.
💡 Points

A flagship CRISPR-era CAR-T name folding over a funding gap says the off-the-shelf cell therapy thesis is struggling to raise money against autologous products and bispecifics. It reads more as a financing failure than a clean scientific verdict, so watch whether the assets and data find a buyer.

Lycia files for a $100M IPO to take its LYTAC degraders into allergy

  • Lycia Therapeutics filed publicly for an IPO of up to $100M on Nasdaq under LYCA, after a confidential filing in July.
  • Its LYTAC platform, from Carolyn Bertozzi's lab, shuttles extracellular proteins to the lysosome for degradation.
  • Lead LCA-0061 degrades IgE for food allergy and is in Phase 1; LCA-0321 targets Graves' disease autoantibodies.
💡 Points

Early healthy-volunteer data showing a deep IgE drop give the story a clinical anchor, and an IPO is a useful test of public-market appetite for degraders outside oncology. The competition is formidable, though: omalizumab and its successors already own IgE, so Lycia must show a durable, differentiated edge.

AstraZeneca Takes a $2B Stake in Summit to Pair Ivonescimab with Its ADCs

  • AstraZeneca is buying $2B of convertible preferred stock, giving it about 12% of Summit's common stock (about 10.6% fully diluted).
  • The first combination pairs Summit's PD-1xVEGF bispecific ivonescimab with AstraZeneca's CLDN18.2-directed ADC in gastrointestinal cancers; a memorandum of understanding covers a broader program with more AstraZeneca ADCs.
💡 Points

This is AstraZeneca buying a seat rather than a pipeline: equity plus combination rights instead of an acquisition or license, keeping it close to a PD-1xVEGF class it doesn't own without paying for the asset outright. The bet is that ADC plus PD-1xVEGF combinations become a next oncology backbone, with AstraZeneca's ADC portfolio as the partner of choice. The broader MOU is non-binding, so definitive terms are the thing to watch.

Basecamp Research Raises $140M to Power New AI Biology Models

  • Basecamp Research, a London-based AI drug design startup, closed an oversubscribed $140M Series C led by S32 at an ~$800M valuation, with Nvidia, Anthropic's Anthology Fund and other investors participating.
  • Funds will train next-generation EDEN foundation models built on the firm's proprietary environmental and biodiversity genomic dataset.
  • The financing advances a pipeline of AI-designed therapeutics, starting with in vivo cell therapies, toward clinical development.
💡 Points

Basecamp isn't training on the same public protein databases every AI-discovery rival uses — its moat is proprietary environmental and biodiversity genomics, genuinely hard to replicate, worth more than the $800M valuation headline. Nvidia and Anthropic both backing one biology-foundation-model shop reads as infrastructure players staking platform claims on bio FMs, and opening the pipeline with in vivo cell therapy instead of small molecules is a far riskier first bet to prove the thesis in clinic.

Enveda Banks $311M Series E, Doubling Valuation to $2B

  • Enveda Biosciences closed a $311 million Series E led by Catalio Capital Management, joined by several new and existing investors.
  • The round roughly doubles Enveda's valuation to about $2 billion and lifts total funding raised past $845 million.
  • Enveda uses AI to mine natural-product chemistry for drug candidates and will use proceeds to push its clinical pipeline, including atopic dermatitis and metabolic disease programs, into later-stage trials.
💡 Points

A $311M Series E in this financing climate signals investors underwriting actual clinical data on two candidates, not just an AI-platform pitch. Enveda's moat is mining natural-product chemical space that synthetic-library-focused rivals ignored; the harder test is atopic dermatitis, where biologics like Dupixent already dominate and a small molecule needs a clear differentiation story to matter.

Nvidia-Backed AI Drug Discovery Startup Iambic Files for Nasdaq IPO

  • Iambic Therapeutics filed for a Nasdaq IPO under ticker IAM, seeking up to $100 million.
  • The AI-native drug discovery company combines machine-learning models with automated wet-lab chemistry, backed by Nvidia and Coatue.
  • Its lead program, an oral HER2 inhibitor called IAM1363, is in early-stage trials for HER2-altered solid tumors.
  • 2025 revenue was about $9 million, while net loss widened to roughly $77 million.
💡 Points

Iambic's IPO is really a referendum on whether public markets still believe in the AI-native drug discovery thesis after Recursion's and BenevolentAI's rocky rides. A $100M raise against a $77M net loss and just $9M in revenue is thin, and Nvidia's and Coatue's names on the cap table are doing more of the selling here than IAM1363's early data.

North Immunology Goes Public via Aethlon Merger, Raises $180M for Eczema Drug

  • North Immunology, incubated for two years inside hedge fund ADAR1 Capital Management, is going public via a reverse merger with Nasdaq-listed Aethlon Medical, trading as North Immunology under new ticker "NRTX"; Aethlon holders keep about 4.75%.
  • Lead asset NOR-101 is a half-life-extended bispecific antibody targeting IL-13 and IL-18, being developed for atopic dermatitis (eczema) as a potential next-generation competitor to Dupixent.
  • The deal includes a $180 million PIPE financing from investors such as Bain Capital, Janus Henderson, and Deep Track Capital, funding operations into the second half of 2028.
  • Phase 1a is planned for early 2027, with interim PK/safety data by mid-2027 and Phase 1b/2b topline results in 2028.
💡 Points

The reverse-merger-plus-PIPE playbook is becoming the default exit ramp for well-capitalized private biotechs in a still-tepid IPO market — expect more of these Nasdaq-shell conversions through 2026 as sponsors sidestep the pricing risk of a traditional roadshow. More interesting is the origin story: ADAR1 Capital incubating NOR-101 in-house for two years before spinning it out is a hedge fund acting like a venture creator, not just a stock-picker — a build-then-monetize model worth watching as more crossover funds chase asset-level returns. Going after IL-13/IL-18 dual blockade puts North squarely in Dupixent's shadow; differentiated mechanism aside, atopic dermatitis is already crowded (Amgen's rocatinlimab, Sanofi/Regeneron's own follow-ons), so competitive execution and pricing power at launch will matter more than novelty. With Phase 1a not starting until 2027, there's no near-term catalyst — this is a story investors have to hold through, not trade around.

Sling Therapeutics Raises $123M to Advance Oral Thyroid Eye Disease Drug

  • Sling Therapeutics closed a $123 million Series C led by Forbion, joined by existing investor TPG Life Sciences Innovations and new investor Sectoral Asset Management.
  • Proceeds will fund Phase 3 development of linsitinib, Sling's oral small-molecule IGF-1R inhibitor, for thyroid eye disease (TED).
  • Unlike IV monoclonal antibodies that bind IGF-1R directly, such as Amgen's Tepezza and Viridian's Lumvoa, linsitinib is taken orally and affects IGF-1R phosphorylation, offering a potentially safer, more durable, more convenient option.
  • Sling has begun dosing patients in its global pivotal Phase 3 ORBIT trial in moderate-to-severe active TED, building on its completed Phase 2b/3 LIDS trial, which met its efficacy goal.
  • The financing positions Sling to compete against an established blockbuster IV therapy market for TED.
💡 Points

Tepezza is a multi-billion-dollar franchise that helped justify Amgen's $27.8B Horizon Therapeutics acquisition — so an oral challenger here isn't just chasing an indication, it's chasing the economics that made that deal work. Forbion leading a $123M round through Phase 3, with TPG re-upping and Sectoral joining fresh, signals real conviction in the differentiation thesis itself, not just TED as a hot category. The commercial logic is straightforward: IV infusions carry site-of-care burden, scheduling friction, and infusion-reaction risk that a pill sidesteps — real value in a chronic, relapsing disease where compliance matters. But incumbents hold prescriber relationships and entrenched reimbursement pathways; an oral entrant more likely peels off infusion-averse or relapsed patients first than displaces frontline share outright, unless Phase 3 data show a decisive edge.

Sling Therapeutics Raises $123M Series C to Advance Oral Thyroid Eye Disease Drug

  • Sling Therapeutics closed a $123 million Series C financing round led by Forbion, with participation from existing investor TPG Life Sciences Innovations and new investor Sectoral Asset Management.
  • Proceeds will fund a Phase 3 trial of linsitinib, an oral small-molecule inhibitor of IGF-1R (insulin-like growth factor 1 receptor), for thyroid eye disease (TED).
  • Linsitinib was originally developed by Astellas as a cancer treatment; Sling licensed the compound in 2022 and repositioned it for TED.
  • The drug is being developed as an oral alternative to Amgen's infused antibody Tepezza (teprotumumab), the current standard treatment for TED.
  • The Phase 3 trial has begun dosing patients, targeting roughly 120 participants, and is evaluating linsitinib's ability to reduce proptosis (eyeball bulging) over a 24-week period.
💡 Points

Tepezza turned thyroid eye disease into a blockbuster franchise despite being an IV-infused biologic — an oral IGF-1R inhibitor now running its own Phase 3 is the first mechanism-matched threat with real clinical data behind it, and Amgen should take notice. The deal's backstory is arguably the sharper story: an Astellas oncology asset shelved, licensed out in 2022, and repositioned for ophthalmology now sits in pivotal testing — the underappreciated-asset playbook every BD team wants to replicate. A $123M Series C landing at Phase 3, not an earlier round, with Forbion leading and new crossover-style investor Sectoral joining incumbent TPG, reads as genuine conviction, not speculative money chasing a hot indication. TED is a small, rare-disease market, but Tepezza proved payers and patients will pay for relief — an oral, self-administered option could expand that funnel further if the proptosis data holds up at 24 weeks.

Encoded Therapeutics Raises $275M Series F for Dravet Syndrome Gene Therapy

  • Encoded Therapeutics closed a $275 million Series F financing round, co-led by GV and an undisclosed healthcare investor, with participation from ARCH Venture Partners, Braidwell, Farallon, Illumina Ventures, Invus, Janus Henderson, Matrix Capital, RTW Investments, SoftBank Vision Fund 2, Venrock and others.
  • Proceeds will fund pivotal and age-expansion studies of ETX101, an AAV9-delivered gene-regulation therapy designed to restore SCN1A gene expression in children with SCN1A-positive Dravet syndrome, a severe and treatment-resistant form of pediatric epilepsy.
  • Interim data from the Phase 1/2 POLARIS trial, presented at the European Epilepsy Congress, showed encouraging reductions in seizure frequency and gains on developmental measures among treated children.
  • The financing will also support manufacturing scale-up and advancement of a second pipeline program, ETX301, targeting post-amputation neuroma pain, toward an IND filing in 2027.
💡 Points

Two hundred seventy-five million is a lot of private capital for a single indication, and it's flowing into gene regulation, not editing or replacement — investors betting that tunable, reversible expression control beats permanent genomic rewrites for a pediatric CNS target. The POLARIS interim data give Encoded first-mover clinical standing in SCN1A-directed Dravet therapy, ahead of gene-replacement and antisense rivals still in earlier stages. The size and syndicate here — GV, ARCH, SoftBank Vision Fund 2 — also reads as a financing-market tell: late-stage private mega-rounds are absorbing capital that might otherwise chase an IPO, a sign the window stays selectively closed. Earmarking part of the raise for ETX301, an unrelated pain asset, is a platform bet — diversification that could dilute focus on the pivotal Dravet push.

Solstice Oncology Launches with $225M Series A, Licenses CTLA-4 Antibody from Harbour BioMed

  • Solstice Oncology launched publicly with an oversubscribed $225 million Series A round, led by a major life-sciences investment firm with support from several other biotech investors.
  • Harbour BioMed granted Solstice an exclusive ex-Greater-China license plus an equity stake to develop porustobart, a next-generation Fc-enhanced CTLA-4 antibody Harbour BioMed discovered.
  • Solstice aims to move the antibody into earlier, neoadjuvant use ahead of surgery, rather than reserving it for later-line metastatic cancer.
  • The approach is backed by earlier data showing porustobart plus a PD-1 inhibitor produced encouraging, durable responses in hard-to-treat MSS colorectal cancer patients without liver metastases.
  • New funds will support a Phase 2 trial combining porustobart with Keytruda, plus a separate Phase 2 colon cancer study opening enrollment later this year.
💡 Points

• Textbook China-to-West playbook: a Western syndicate (RA Capital-led) capitalizes a new US NewCo to develop a China-originated clinical asset outside Greater China — now the default route for getting Chinese-discovered biologics into global markets. • License-plus-equity, not a straight license, is the tell: Harbour BioMed keeps upside tied to Solstice's success rather than taking cash alone, and an oversubscribed $225M Series A for a single asset signals unusually strong investor conviction. • The real strategic bet is timing — pushing porustobart into neoadjuvant use instead of crowded late-line CTLA-4/PD-1 combinations is differentiated, but also less-trodden regulatory and commercial ground. • Everything hinges on execution: the prior 'encouraging' late-line colorectal data is rationale, not proof; the coming Keytruda-combo and colon cancer Phase 2 readouts are the real test of the thesis.

TwoStep Therapeutics Lands $62.5M and FDA IND Clearance for Peptide-Based ADC Alternative

  • TwoStep Therapeutics, a 2024 Stanford spinout, announced an oversubscribed $62.5M Series A financing on September 10, 2026, alongside FDA clearance of the investigational new drug (IND) application for its lead candidate, TS-104.
  • The round was led by Insight Partners and Medical Excellence Capital, with pharma-linked corporate venture arms M Ventures (Merck KGaA) and Pfizer Ventures co-leading; existing investors NFX, 2048 Ventures, and Stanford University also participated, bringing total funding raised to $71.2M.
  • TS-104 is a first-in-class multi-specific peptide-drug conjugate (PDC) that pairs a polyspecific integrin-binding peptide, engineered to bind five tumor-associated integrins across solid tumors, with the cytotoxic payload MMAE, also used in several approved antibody-drug conjugates.
  • The company positions this peptide-based platform as an alternative to antibody-based ADCs for reaching solid tumor targets.
  • The IND clearance opens the way for a first-in-human Phase 1 trial, with patient enrollment expected later this year.
💡 Points

PDCs are pitching themselves as the cheaper, more tumor-penetrant cousin of ADCs — same MMAE payload, smaller delivery vehicle, potentially better access to solid-tumor stroma where antibodies struggle. That's a direct pitch at the ADC franchise now dominating oncology dealmaking. The investor list matters more than the dollar figure: M Ventures and Pfizer Ventures co-leading, not just writing a check, reads as two ADC-heavy pharmas hedging their own franchises and buying an early look at a modality that could either complement or cannibalize their antibody platforms. Oversubscribed Series A plus IND clearance inside two years of founding is a fast validation cycle for a still-unproven conjugate class — worth watching whether Phase 1 tolerability holds up before any partnering thesis gets real.

ARPA-H Bets $125M on On-Demand, Personalized RNA Manufacturing

  • ARPA-H is funding automated manufacturing systems to produce personalized RNA medicines near the point of care in under a week, awarding up to $125M across five teams under its GIVE program.
  • The largest award, up to $54.5M, went to Waterfall Scientific, which leads a six-company consortium building a continuous-flow, cell-free mRNA manufacturing and characterization platform (project ESCALATOR).
  • Consortium partners include Ansa Biotechnologies (enzymatic DNA synthesis), Volta Labs (automated fluid handling), Polymorphic Biosciences (LNP formulation), Tensentric (hardware engineering) and Ginkgo Bioworks.
  • Goal: compress custom RNA drug production timelines from months to days, enabling distributed, patient-proximate manufacturing without sacrificing quality.
💡 Points

ARPA-H is capitalizing infrastructure here, not a specific drug — Waterfall's $54.5M award and the government's stamp of approval become leverage for the consortium's next fundraising or partnering conversations. Non-dilutive capital validating a shared-infrastructure model lowers the barrier for N-of-1 and other personalized RNA programs smaller biotechs could never justify building dedicated GMP capacity for. For Ansa, it validates enzymatic DNA synthesis as a manufacturing input beyond its core synbio pitch; for Ginkgo, it's another foundry contract reinforcing the picks-and-shovels positioning it's leaned on since COVID-testing revenue dried up. Washington is treating rapid, decentralized genetic-medicine manufacturing as a national-capability question now, not just a therapeutic one.
