- Ten innovative biologics are seen as frontrunners for approval in 2026, spanning rare diseases (tividenofusp alfa, atacicept), autoimmune disorders (ianalumab, rocatinlimab, imsidolimab), infectious disease vaccines (VLA15 for Lyme, mRNA-1647 for CMV), gene/enzyme therapies (ABBV-RGX-314, imlifidase), and cell therapies (tabelecleucel).
- Candidates like ABBV-RGX-314 (wet AMD gene therapy) and vaccines (Lyme, CMV) could reshape markets with one-time or preventive treatments, while autoimmune mAbs promise better efficacy and convenience compared to current standards. Rare disease therapies, though smaller in population, may secure high-value orphan niches.
- Innovative biologics and therapies are expected to comprise ~60% of new drug approvals by 2030. The 2026 wave reflects a shift toward precision, durable, and more patient-friendly regimens.
Paving the way for 2026 approvals
The biopharmaceutical landscape continues to evolve at a remarkable pace, driven by breakthroughs in targeted therapies, novel modalities, and a deepening understanding of disease mechanisms. As we approach 2026, the anticipated approvals of innovative biologics promise to address unmet needs across rare diseases, autoimmune disorders, infectious threats, and chronic conditions. This article highlights 10 drugs/vaccines that, according to our assessment, have the highest probability of being approved in 2026. These are: tividenofusp alfa, tabelecleucel, VLA15, imlifidase, mRNA-1647, ABBV-RGX-314, ianalumab, rocatinlimab, imsidolimab, and atacicept.
In 2024, the FDA approved 50 novel drugs, with biologics comprising approximately 32% (16) of these approvals (Figure 1).1 Biologics shone in areas such as oncology, where nearly half of first-quarter approvals were biologics or biosimilars, and vaccines, with notable advancements like the CAPVAXIVE pneumococcal conjugate vaccine. The approval of 13 new monoclonal antibodies, accounting for more than 25% of drugs greenlit in 2024, set a new record.

This year started at a slow pace but in mid-2025, approvals accelerated, with a total of 27 novel drug therapies authorized by the end of August.3 Nine of them were innovative biologics, among which the most notable were garadacimab and donidalorsen – breakthrough medicines for the treatment of hereditary angioedema. In addition to novel molecules, FDA approved many new vaccines and biosimilars, including first-ever biosimilars to insulin aspart, as well as expanded labels for several already available products such as durvalumab.
Looking to 2026 and beyond, the biologics pipeline is poised for transformative growth, with some analytics forecasting over 60% share of biologics and gene therapies in new drug approvals by 2030.4 Among the highlighted candidates, several hold blockbuster potential, defined today as exceeding $3 billion in annual sales, due to large patient populations and unmet needs (Figure 2). For instance, ABBV-RGX-314, a one-time gene therapy for wet age-related macular degeneration (AMD) and diabetic retinopathy, targets a market of millions affected by vision loss, potentially rivaling established anti-VEGF therapies like aflibercept.5 Similarly, vaccines like VLA15 (Lyme disease) and mRNA-1647 (cytomegalovirus) could achieve widespread adoption in endemic regions, generating blockbuster revenues through preventive care models.6,7Autoimmune-focused mAbs such as Ianalumab (for Sjögren’s disease), rocatinlimab (atopic dermatitis), and imsidolimab (generalized pustular psoriasis) are likely contenders, addressing chronic, high-prevalence conditions with durable responses and fewer injections than current standards. Rare disease therapies like tividenofusp alfa (Hunter syndrome) and atacicept (IgA nephropathy) may not reach blockbuster status but could command premium pricing due to orphan designations and limited competition.
Figure 2 A selection of 10 most interesting biologics with high probability of approval in 2026.

The biopharmaceutical industry’s focus is sharpening on immunology and autoimmunity, with mAbs and fusion proteins (e.g., targeting BAFF-R, OX40, IL-36R) leading R&D efforts for their precision and tolerability. Advanced therapies, including gene editing, mRNA platforms, and allogeneic cell products – are expanding into ophthalmology and infectious diseases, promising one-time cures over lifelong treatments. However, challenges like manufacturing scalability, long-term safety (e.g., immune responses in gene therapies), and equitable access persist. With AI accelerating discovery and regulatory pathways like FDA Breakthrough designations expediting approvals, 2026 could mark a pivotal year for innovative biologics, potentially reducing treatment burdens and improving outcomes for millions.
Fusion proteins that treat the hard-to-treat
■ Tividenofusp alfa (Denali/BioMarin)
Hunter syndrome is a progressive X-linked genetic disorder in which the absence of iduronate-2-sulfatase (IDS) causes harmful accumulation of glycosoaminoglycans in various organs and tissues. For years, enzyme replacement therapy (ERT) has been used to drain these molecules from patients’ bodies but couldn’t touch what mattered most to families: the neurological decline that starts in early childhood.8 Tividenofusp alfa is built to change that equation. It takes the missing enzyme, iduronate-2-sulfatase (IDS), and fuses it to an engineered “TransportVehicle™” that recognizes the transferrin receptor on the blood–brain barrier (Figure 3). Think of it as hitching a ride on a legitimate courier to cross the checkpoint; once inside, the cargo is handed off to lysosomes in brain and peripheral tissues alike. Early human studies reported that the enzyme didn’t just nibble at biomarkers – it drove cerebrospinal fluid heparan sulfate toward normal and kept it there over long follow-up, alongside encouraging gains in hearing, cognition and adaptive behavior. That durability, plus a tolerability profile dominated by manageable infusion-related reactions, convinced regulators to let the program move quickly. In July 2025, the FDA accepted Denali’s application for accelerated approval, granted Priority Review, and posted a January 5, 2026 target decision date – an unusual show of urgency in a disease that hasn’t seen a step-change in almost two decades.10,11The pivotal foundation is pragmatic as well as ambitious. Denali continues to run COMPASS, a randomized Phase 2/3 study enrolling in North and South America and Europe, to support broader approvals beyond the first U.S. decision.12 Notably, COMPASS pits tividenofusp directly against idursulfase – the incumbent peripheral ERT – at a 2:1 randomization, a design that should help quantify the clinical value of brain delivery instead of relying on indirect comparisons. Regulators have also signaled comfort with the platform’s trajectory by layering on Fast Track and Breakthrough Therapy in the U.S. and PRIME in the EU, a trio of designations that typically comes with close scientific dialogue on endpoints, manufacturing controls and post-marketing commitments.

If approved on schedule, the near-term questions will be practical ones that CDMOs and treatment centers can solve together: how to guarantee lot-to-lot consistency for an engineered fusion (ensuring the transferrin-receptor binding and IDS activity stay synchronised), how to desgin release assays that capture both parts of the molecule’s job, and how to track neurocognitive outcomes in the real world once biomarkers have normalized. Families will care about the lived experience – weekly or biweekly infusion routines, infusion-center capacity, and whether earlier treatment changes developmental trajectories. For biopharma industry, the stakes are even higher: a first BBB-penetrant ERT would validate receptor-mediated shuttling for other lysosomal and neurodegenerative targets, opening up a new important lane for the treatment of hitherto incurable CNS diseases.
■ Atacicept (Vera Therapeutics)
IgA nephropathy is a chronic kidney disease in which IgA antibodies build up in the glomeruli, causing inflammation and tissue destruction. It is often treated downstream, where proteinuria shows up and kidneys are already straining. Atacicept tries to turn off the tap closer to the source. It’s a TACI-Fc fusion protein that joins two B-cell survival cytokines – BAFF and APRIL – that help sustain the cells producing the aberrant galactose-deficient IgA1 thought to kick-start the disease.13 In June 2025, Vera announced that its pivotal ORIGIN study hit the mark: patients on atacicept saw about a 46% reduction from baseline in proteinuria and a 42% advantage over placebo at week 36, a magnitude that resonates clinically and statistically. Safety tracked close to placebo in the topline cut, and the company set out a straightforward plan: submit a BLA in Q4 2025 for accelerated approval, then read out longer-horizon kidney function to convert to full approval. That timeline puts a U.S. decision squarely in 2026, which is exactly what nephrology clinics have been preparing for.14,15
Because accelerated approval in kidney disease leans on surrogates, everyone will watch eGFR over time. Here the backdrop is reassuring: earlier controlled and extension data suggested stabilization trends, and the ongoing extension of the ORIGIN study is designed to deliver the three-year kidney function curves reviewers want to see.16 Results at 96 weeks of follow-up were highly encouraging, demonstrating continuing reduction in proteinuria and preservation of glomerular filtration capacity.17
Meanwhile, the day-to-day realities favor a biologic in chronic care: atacicept is administered once-weekly via subcutaneous route, meshing well with nursing-led programs and home treatment.14 If approved, expect positioning as a disease-biology therapy rather than a symptomatic add-on – potentially used alongside SGLT2s and, where appropriate, tapered steroids. For CDMOs, the near-term work is classic but nontrivial: reproducible glycoforms, a tight handle on Fc-fusion biophysics, and validated potency assays that reflect dual BAFF/APRIL neutralization. For payers, the cost-effectiveness considerations will revolve around the proteinuria effect size, early eGFR signals, and how atacicept stacks against complement-pathway drugs now moving through the same clinics.16,17
Smarter switches for misfiring immunity
■ Ianalumab (Novartis)
Sjögren’s has long sat in therapeutic limbo: too complex for symptomatic care alone, yet historically unrewarding for targeted drugs. Ianalumab changes the conversation by going straight to the survival signal that keeps autoreactive B cells in play – BAFF acting through its BAFF-R receptor.18 Blocking the receptor rather than the ligand appears to matter; in August 2025, Novartis reported that both of its global Phase 3 studies, NEPTUNUS-1 and NEPTUNUS-2, met their primary endpoints on disease activity, the first time any program has convincingly moved the needle at this scale in Sjögren’s.19 The two trials covered complementary dosing patterns (monthly IV and flexible SC schedules) and together enrolled several hundred patients, with safety described as favorable in topline updates. In August 2026 another good news arrived as ianalumab was announced to delay treatment failure in immune thrombocytopenia (ITP), another autoimmune condition in which BAFF protein seems to play a pivotal role.20
Novartis says it will take the package to regulators worldwide, setting up a 2026 decision window and, potentially, a first targeted therapy for this condition.21 For clinicians, the appeal is obvious: a route to tamp down the B-cell biology that drives systemic manifestations of numerous autoimmune diseases; for payers, the story will hinge on the size and duration of patient-reported gains as well as steroid-sparing effects. If the filings proceed in line with the assumed timeline, Sjögren’s clinics could be re-tooling their care pathways as early as next year.
■ Rocatinlimab/AMG-451 (Amgen/Kyowa Kirin)
Atopic dermatitis is a crowded indication when it comes to therapeutic modalties, but many patients still cycle through different options because the usual cytokine suspects don’t fully capture their disease. Rocatinlimab comes at the problem from a different angle than other drugs, dampening the OX40 costimulatory signal that helps sustain pathogenic T-cell responses. That idea now has late-stage momentum behind it: in March 2025 Amgen and Kyowa Kirin reported that the pivotal ROCKET IGNITE trial met co-primary and all key secondary endpoints across two dose strengths versus placebo, while earlier ROCKET HORIZON data showed clinically meaningful proportions of patients achieving near-clear skin on a validated global assessment.22,23 The sponsors emphasize durability as well, pointing to longer-term maintenance in extension cohorts and to extended-interval dosing that could ease clinic flow and patient burden.24
Global responsibilities are clear, Amgen leads ex-Japan with co-promotion options for Kyowa Kirin, so if filings land as guided, 2026 approvals look realistic. In practice, dermatologists may position rocatinlimab for patients who need a mechanistic alternative to IL-4/IL-13 blockers or who value less frequent maintenance dosing, while health systems weigh comparative effectiveness and visit intensity against entrenched incumbents.
Figure 4 Results of the pivotal Phase 3 trial of imsidolimab (GEMINI-1) showing outstanding efficacy in generalized pustular psoriasis.

■ Imsidolimab (Vanda/Anaptys)
Few conditions demand speed like generalized pustular psoriasis, where neutrophilic flares can turn life-threatening within days.25 The IL-36 pathway sits at the center of this storm, and imsidolimab, an antibody against the IL-36 receptor, has completed two registration-enabling trials, including phase 3 GEMINI-1 trial, showing rapid disease control and maintained clarity (Figure 4).26,27
In February 2025, Vanda secured global rights from Anaptys and moved straight into technology transfer and regulatory preparation for the U.S. and EU.28 That sequence matters because it suggests confidence not only in efficacy but also in the manufacturability and release testing needed for a rare-disease launch.
With class precedent already established for IL-36 blockade, reviewers are familiar with endpoints and safety monitoring; the differentiators are likely to be dosing practicality, durability through subsequent flares, and real-world immunogenicity. Assuming the filings track to plan, 2026 becomes a credible first approval year – one that would expand clinician choice in a setting where options are limited and time is precious.
New shields against old pathogenes
■ VLA15 (Valneva/Pfizer)
For the first time in decades, a human Lyme vaccine is within touching distance. The previous vaccine, LYMErix, was approved in 1998, only to be voluntarily withdrawn four years later by its manufacturer after sudden sales collapse amid lawsuits and never substantiated claims of vaccine-induced arthritis. Post-licensure monitoring and FDA review in 2001 did not find higher rates of arthritis in vaccinated people compared with controls, yet the damage to confidence was already done; uptake fell from about 1.5 million doses in 1999 to roughly 10,000 by 2002, and the product was pulled despite the absence of a safety signal. Public-health historians now point to LYMErix as a cautionary tale about how litigation and misinformation can sink an effective vaccine even when advisory reviews and safety data are reassuring.30
VLA15 is built on the same fundamental idea – neutralizing outer surface protein A (OspA) to block Borrelia transmission from tick to human – but it reflects two decades of progressive learning. Where LYMErix targeted a single OspA from B. burgdorferi sensu stricto (the dominant North American species), VLA15 is multivalent, covering six OspA serotypes to address the broader species complex circulating across North America and Europe.31 Early clinical studies have shown the multivalent formulation to be immunogenic and generally well tolerated, and the pivotal VALOR trial is designed around physician-confirmed Lyme as an endpoint rather than surrogate immunobridging alone.
After weathering a disruption in 2023 caused by a GCP-noncompliant site network, the enrollment in VALOR trial was quickly rebuilt and the recruitment is now complete.32 The vaccine developers, Valneva and Pfizer, have repeatedly reiterated their plan to file on both sides of the Atlantic in 2026, contingent on clean efficacy and safety.33 That cadence is echoed across company pages and press releases and has been picked up by trade coverage, which also notes recently reported Phase 2 booster data showing a solid anamnestic response after a third annual dose – useful real-world scaffolding for a long-term schedule. If VALOR lands as expected, the launch narrative becomes almost self-evident: seasonal clinics in high-incidence states and regions, employer and travel programs for outdoor workers, and pediatric inclusion that broadens public-health reach. For CDMOs, this is classic protein-subunit craft with a twist – lot-to-lot immunogenicity across six OspA variants, clarity on booster manufacturing slots, and strain coverage that will need periodic reconfirmation as surveillance evolves.
■ mRNA-1647 (Moderna)
Cytomegalovirus is the quiet antagonist of maternal-fetal medicine – common, often unnoticed, yet a leading infectious cause of birth defects.33 Unfortunately, previous efforts to create an effective vaccine proved elusive.34 Now, a new kid on the block, mRNA-1647 vaccine created by Moderna, tries to shut the door before infection ever takes hold by encoding multiple CMV antigens, most notably the pentamer complex and glycoprotein B. within a single lipid-nanoparticle formulation.35
Early-stage studies of mRNA-1647 consistently showed robust neutralizing responses in both seronegative and seropositive adults, and the pivotal CMVictory (P301) trial is now fully enrolled in women aged 16-40.36,37 A prespecified early-efficacy look did not trigger, but the independent data-safety board has reported no safety concerns and recommended continuation, and public materials from U.S. vaccine advisors have begun sketching the policy questions regulators will weigh if efficacy reads out convincingly.38 Moderna has been guiding investors to a 2026–2028 commercialization window; if the final analysis in late 2025 is positive and filings move briskly, 2026 becomes plausible.39 For manufacturers and public-health programs alike, the attraction is clear: an antigen-updateable platform suited to large-scale maternal immunization, standardized LNP analytics that regulators increasingly recognize, and a deployment model that could be integrated into routine reproductive-age care. The gating item is efficacy against primary infection; if that hurdle is cleared, this program graduates from scientific ambition to a durable public-health tool.
Restoring anti-viral control with allogenic T cells
■ Tabelecleucel/Tab-cel (Atara)
Transplant physicians have always known that the best therapy for EBV-positive post-transplant lymphoproliferative disorder (PTLD) would be the very thing immunosuppression takes away: virus-specific T cells. Tab-cel makes that idea practical by banking partially HLA-matched, EBV-experienced donor T cells and releasing them off the shelf when PTLD emerges after an allogeneic transplant or a solid-organ graft.40 The promise is speed. Instead of waiting weeks to manufacture a bespoke autologous product while cancer accelerates, hospitals can order a pre-qualified lot, match it, and infuse. The clinical story that built to filing mixes expanded-access experience with prospective studies in a population with almost no approved options, where objective responses translate into survival gains and quality-of-life wins that matter to families.
EMA has already approved tabelecleucel under exceptional circumstances, acknowledging the paucity of effective treatments for EBV+ PTLD.41,42 After several iterative CMC and inspection steps, the FDA accepted Atara’s resubmission and granted Priority Review with a January 10, 2026 action date; if cleared, tab-cel would inaugurate a new class of allogeneic, virus-specific T-cell therapies at CBER and give transplant centers a standardized playbook for EBV-driven disease.43
Post-marketing will almost certainly track lot-to-lot consistency and long-term persistence and monitor for GVHD signals, but the core risk-benefit lens is favorable in this setting and the urgency is obvious at the bedside.
Closer look at new gene therapy
■ ABBV-RGX-314 (AbbVie/REGENXBIO)
Wet age-related macular degeneration (AMD) has been a triumph of biologics and a burden of logistics. Millions of clinic visits each year are spent on anti-VEGF injections that rescue vision but demand relentless adherence.44,45 ABBV-RGX-314 aims to solve this issue with a one-time AAV8 vector that turns the retina into its own anti-VEGF factory after a subretinal procedure.46 Pivotal programs called ATMOSPHERE and ASCENT are the decision-makers here, and both are geared to answer not only whether vision can be maintained, but whether injection burden can be sustainably reduced versus state-of-the-art comparators like aflibercept.47 Pivotal wet-AMD readouts planned for 2026 have set expectations appropriately: if efficacy and safety are decisive and filings move swiftly, a late-2026 decision could happen.48
For AMD patients, approval of ABBV-RGX-314 would mark a significant progress, offering a one-time treatment instead of repeated injections. For payers and health systems, the high costs of novel gene therapy are likely to be counterbalanced by multi-year capacity relief in crowded retina clinics. For CDMOs and vector manufacturers, this is about reproducible AAV quality attributes, surgeon-friendly DP presentations, and solid comparability as programs transition from Phase 3 to launch.
Enzymatic match-maker
■ Imlifidase (Hansa)
Highly sensitized kidney-transplant candidates often stall at the last step: a positive crossmatch that predicts catastrophic rejection.49 Imlifidase offers a timed reset. It’s a bacterial endopeptidase that quickly cleaves human IgG, transiently clearing the donor-specific antibodies that block transplantation and opening a window in which a graft can take.50 Europe granted conditional approval in 2020 for this desensitization use, paired with a real-world effectiveness commitment.51 In the United States, momentum has been building: the pivotal, randomized ConfIdeS study completed recruitment and randomization, and its 12-month eGFR endpoint is designed as a surrogate reasonably likely to predict long-term benefit under the accelerated-approval framework.52 Hansa has repeatedly pointed to a H2-2025 BLA submission, setting up a potential 2026 FDA decision if the effect size and safety prove persuasive.53 It’s a niche, center-driven intervention but transformative for the people it reaches; for transplant programs and manufacturers alike, the operational challenge is choreography – synchronizing drug timing, organ allocation, and immunosuppression while ensuring dependable enzyme activity and lot release across sites.
A short summary of all innovative biologics discussed in our article is presented in Table 1.
Crossing barriers, changing care: the biologics wave of 2026
From a brain-penetrant enzyme replacement for Hunter syndrome to an off-the-shelf T-cell therapy for EBV-driven post-transplant disease – this year’s wave of biologics shows how far the modern medicine has reached. The BBB-shuttled fusion protein tividenofusp alfa crystallizes the promise of getting large molecules into protected compartments and aims to reset expectations in lysosomal disease by addressing CNS decline, not just peripheral biomarkers. At the other end of the spectrum, tabelecleucel turns the long-imagined idea of banked, virus-specific T cells into a practical, ready-to-use medicine for a population that can’t wait weeks for custom manufacturing. Together, they define a new era in biologic therapies, where seemingly unreachable targets finally become within our reach.
Vaccines reassert their public-health muscle, but this time aiming at completely different pathogens, for which no effective prevention methods are available. VLA15, a multivalent OspA subunit shot, is poised to bring the first human Lyme vaccine in decades to North America and Europe, a timely answer to expanding tick ranges and rising incidence of borreliosis. In parallel, Moderna’s mRNA-1647 could inaugurate a long-sought CMV vaccine for women of childbearing age, translating strong immunogenicity in early studies into population-level prevention if Phase 3 efficacy lands. For CDMOs, these programs blend familiar crafts – protein subunits and LNP-mRNA – with modern demands: multi-valent lot consistency, rapid strain/antigen updates, and seasonal scale that flexes without sacrificing release speed or quality.
Ianalumab, a BAFF receptor blocker, may deliver the first targeted therapy for Sjögren’s disease and signal a pivot toward B-cell pathway precision in conditions long managed with symptomatic care. Rocatinlimab brings a mechanistic alternative in atopic dermatitis by dialing down OX40 costimulation and, with it, the pathogenic T-cell circuits that escape IL-4/IL-13 blockade – promising fewer visits through extended-interval maintenance. In dermatology’s most acute corner, imsidolimab extends the IL-36 class with a second option for generalized pustular psoriasis, turning days-to-control into a realistic goal and giving clinicians a choice in dosing and durability. These antibodies underscore a broader 2026 theme: not just more biologics, but better-targeted ones that meet patients where current standards fall short. Gene and enzyme interventions round out the year’s “one-and-done” and “just-in-time” stories. ABBV-RGX-314, an AAV8 vector delivering a retinal anti-VEGF, aims to swap monthly injections for a single procedure in wet AMD, shifting the health-system math to operating-room time and forcing payers to weigh sky-high upfront cost against multi-year capacity relief. Imlifidase, a bacterial protease that cleaves human IgG, opens a narrow window for highly sensitized kidney-transplant candidates, in which a life-saving graft can proceed. And in nephrology, atacicept, a TACI-Fc fusion that merges BAFF and APRIL, pushes the field upstream in IgA nephropathy by targeting the autoantibody machinery that drives disease rather than merely treating proteinuria downstream.
The 2026 is expected to be yet another year bringing a huge wave of innovative biologics. Although the recent years were marked by stagnation in terms of the number of FDA-licensed biologics, the outlook remains optimistic – share of biologics among all approved drugs is forecasted to reach 60% by 2030.4 The dominance of monoclonal antibodies and other therapeutic proteins is likely to continue in 2026 and beyond, however new modalties, such as cell and gene therapies or RNAs, are getting traction and may eventually dethrone the more “classic” biologics. Another visible trend in recent years is the increasing availability of medicines for rare or often neglected conditions. Next year will be no different in this respect – we will witness the appearance of a breakthrough treatment for Hunter disease and, if Phase 3 proves positive, first-ever vaccine against cytomegalovirus. Another recurring theme is the development of drugs against already validated targets, but with more convenient administration route or dosing scheme. The finest example of such progress is the already discussed gene therapy for wet AMD, which limits the treatment to only one injection.
For patients, that all adds up to something simple and long awaited: biologics that not only work but fit into lives – fewer injections, fewer flares, fewer missed chances at a transplant or healthy birth. For the innovative biologics industry and its CDMO partners, 2026 isn’t just another step forward; it’s a clear signal that precision in design, delivery, and deployment will be now the standard, not the exception.
