Late-Stage Pipeline Watch: 71 Verified Catalysts to Track H2 2026 Through 2028
Across our internal biotech cohort, 71 publicly-verified upcoming catalyst events sit in the database — 17 with exact PDUFA/readout dates, 51 in sponsor-stated quarters, and 3 still TBD. Today's breakdown covers Q3 2026 (17), Q4 2026 (18), and H1 2027 (12), plus the cross-cutting conference placements, the 41 H1-2026 items we deliberately crossed off the calendar, and one notable caveat (an outlook-therapeutics 4th BLA resubmission) that explains why some 'exact date' PDUFAs are actually long-shot recoveries.
If you have spent the last six months waiting for “something biotech” to happen on the calendar, the answer is arriving, all at once, between July and December 2026. Across our internal cohort research and three parallel verification passes we ran this week, 71 publicly-sourced upcoming catalyst events are stacked into H2 2026 and the first half of 2027 for the biopharma sponsors on our watchlist. Seventeen have exact PDUFA or readout dates confirmed via sponsor IR press releases. Fifty-one sit inside sponsor-stated windows. Three remain TBD with no public guidance yet.
This is the kind of calendar where the actionable signal is in the precision tier, not the headline count. Knowing that Scholar Rock’s apitegromab BLA has a Sep 30, 2026 PDUFA is materially different from knowing that Regeneron has a fenebrutinib filing “planned for H2 2026.” Both will move the stock. Only one is tradeable on a calendar.
Why the precision split matters
We label every event with one of three date tiers:
| Tier | What it means | Example this cycle |
|---|---|---|
| DATE | FDA action date confirmed in an FDA-citable calendar or sponsor press release | Scholar Rock apitegromab BLA, Sep 30, 2026 |
| WINDOW | Sponsor-stated quarter/half (e.g. “Q3 2026,” “H1 2027”) without a firm day | Viking Therapeutics VK2735 SC VANQUISH-1, Q3 2026 (sponsor guidance) |
| TBD | No public guidance, no FDA action date, no completed trial | Madrigal resmetirion MAESTRO-NASH-OUTCOMES, 2027+ (primary completion 2027; readout timing not yet guided) |
If you are sizing a position around a H2 2026 readout, 17 DATE-tier catalysts are the only ones worth scripting against as binary events. The other 51 are window-trades with intrinsic timing uncertainty — sometimes the window holds and the catalyst lands on time, sometimes it slips and you wait another quarter.
Q3 2026 (Jul-Sep) — 17 catalysts
The dense first half of Q3 is dominated by late-July / August PDUFA stack and a cluster of Hematology decisions.
| Date | Catalyst | Sponsor | Indication | Precision |
|---|---|---|---|---|
| Jul 29, 2026 | ONS-5010 wet-AMD BLA PDUFA — 4th resubmission after 3 prior CRLs | Outlook Therapeutics | Wet AMD | DATE |
| Aug 2026 | Garetosmab BLA PDUFA — Priority Review | Regeneron | Fibrodysplasia ossificans progressiva (FOP) | DATE |
| Aug 17, 2026 | Iberdomide + dara + dex (IberDd) PDUFA | Bristol-Myers Squibb | R/R multiple myeloma (post-CD38) | DATE |
| Aug 24, 2026 | Lecanemab SC starting-dose PDUFA — extended from May 24 | Eisai / Biogen | Early Alzheimer’s | DATE |
| Sep 1, 2026 | Camizestrant SERENA-4 Phase 3 topline | AstraZeneca | 1L HR+/HER2- advanced BC + CDK4/6i | DATE |
| Sep 19, 2026 | UX111 (rebisufligene etisparvovec) BLA PDUFA | Ultragenyx | Sanfilippo syndrome type A (MPS IIIA) | DATE |
| Sep 30, 2026 | Apitegromab BLA PDUFA — resubmission accepted May 2026 | Scholar Rock | Spinal muscular atrophy (SMA) | DATE |
| Q3 2026 | Ziltivekimab ZEUS readout — primary completion Jun 2026 | Novo Nordisk | CV events in CKD + inflammation | WINDOW |
| Q3 2026 | Pelacarsen Lp(a)HORIZON — event-driven, now H2 2026 | Novartis / Ionis | CV events with elevated Lp(a) | WINDOW |
| Q3 2026 | Retatrutide TRIUMPH-2 topline | Eli Lilly | Obesity + T2D | WINDOW |
| Q3 2026 | Survodutide SYNCHRONIZE-2 topline | Boehringer Ingelheim | Obesity + T2D | WINDOW |
| Q3 2026 | Pemvidutide RECLAIM AUD Phase 2 topline | Altimmune | Alcohol use disorder | WINDOW |
| Q3 2026 | VK2735 SC VANQUISH-1 interim / maintenance data | Viking Therapeutics | Obesity | WINDOW |
| Q3 2026 | Skyrizi SC induction CD — PDUFA | AbbVie | Crohn’s disease (SC induction) | DATE |
| Q3 2026 | Lebrikizumab pediatric sNDA filing (6mo-<12yr) | Eli Lilly | Atopic dermatitis (pediatric) | WINDOW |
| TBD | Survodutide LIVERAGE-1 MASH readout | Boehringer Ingelheim | MASH + fibrosis | TBD |
The pattern worth highlighting: five consecutive BLA PDUFA dates between Aug 17 and Sep 30 (iberdomide, lecanemab SC, camizestrant readout, UX111, apitegromab) plus garetosmab’s Priority Review in early August. If you are running an event-driven book around August and early September, this is the concentration of risk.
Q4 2026 (Oct-Dec) — 18 catalysts
Q4 is where label expansions stack up — most of the field’s commercially-meaningful revenue events are PDUFA targets gated by H2 2026 confirmatory data.
| Date | Catalyst | Sponsor | Indication | Precision |
|---|---|---|---|---|
| Nov 30, 2026 | Giredestrant adjuvant (lidERA) PDUFA — Priority Review | Roche | Adjuvant ER+/HER2- early BC | DATE |
| Nov 2026 | Cemdisiran + pozelimab PDUFA — Priority Review (gMG) | Regeneron | Generalized myasthenia gravis | DATE |
| Dec 18, 2026 | Giredestrant + everolimus (evERA) PDUFA | Roche | ESR1-mutated ER+/HER2- advanced BC | DATE |

| Q4 2026 | Rinvoq vitiligo — PDUFA expected | AbbVie | Vitiligo | WINDOW |
| Q4 2026 | Mezigdomide sNDA filing — post-SUCCESSOR-2 positive (EHA Jun) | Bristol-Myers Squibb | R/R multiple myeloma | WINDOW |

| Q4 2026 | Lete-cel BLA filing — synovial sarcoma & MRCLS | Adaptimmune | NY-ESO-1 TCR-T | WINDOW |
H1 2027 (Jan-Jun) — 12 catalysts
Most H1 2027 items are P3 topline readouts, not PDUFAs. Conference placement matters: ESMO (Oct 23-27, Madrid) was 2026’s — ESTRO 2027 has not been officially mapped, SABCS 2026 (Dec San Antonio) will set the tone for breast-cancer 2027 narrative, and ASH 2026 (Dec San Diego) closes the year for hematology.
| Window | Catalyst | Sponsor | Indication | Precision |
|---|---|---|---|---|
| Q1 2027 | Suzetrigine DPN Phase 3 readout | Vertex Pharmaceuticals | Diabetic peripheral neuropathy | WINDOW |
| Q1 2027 | Osavampator Phase 3 MDD topline | Neurocrine Biosciences | Major depressive disorder | WINDOW |
| H1 2027 | Linvoseltamab LINKER-MM3 Ph3 topline | Regeneron | R/R multiple myeloma | WINDOW |

| H1 2027 | Kymera KT-621 BROADEN2 AD Phase 2 topline | Kymera Therapeutics | Atopic dermatitis | WINDOW |
| Q2 2027 | Survodutide LIVERAGE MASH topline | Boehringer Ingelheim | MASH + fibrosis | WINDOW |
| 2027+ | Elritercept (KER-050) RENEW Ph3 | Keros / Takeda | Anemia in LR-MDS | TBD |
The 41 H1 2026 events we crossed off the calendar
A frequently-overlooked discipline in calendar work is the deliberate removal of items that already happened. This cycle we explicitly cut 41 catalysts that pre-trained model snapshots had listed as “upcoming 2026” but which had already read out, been approved, or failed before we ran this verification pass.
Major approvals (H1 2026) that have already removed from the upcoming table:
- Orforglipron (Foundayo) — FDA approved April 1, 2026 (oral GLP-1 for T2D)
- Retatrutide TRIUMPH-1, TRIUMPH-3, TRIUMPH-4, TRANSCEND-T2D-1 — all positive (Apr-May 2026)
- Vepdegestrant (Veppanu / ARV-471) — FDA approved May 1, 2026 (first PROTAC ever approved, ESR1-mutated ER+ BC)
- Dato-DXd (Datroway) — FDA approved May 22, 2026 (unresectable/metastatic TNBC)
- Sonrotoclax (Beqalzi) — FDA approved May 13, 2026 (accelerated, R/R MCL)
- Filspari FSGS indication — FDA approved April 13, 2026
- Survodutide SYNCHRONIZE-1 (obesity) — positive 16.6% weight loss, NDA filing H2 2026 (this is still future; the readout itself is past)
- Imdelltra DeLLphi-304 — positive OS (Q4 2025)
- Mezigdomide SUCCESSOR-2 — positive at EHA Jun 11-14, 2026 (NDA filing now the future event)
- Amlitelimab COAST 1/2 AD — primary endpoints met March 2026
- Apitegromab SAPPHIRE — met primary Oct 7, 2024 (the Sep 30 BLA PDUFA is the gate)
- Imunnevestment GYM329 / emugrobart — discontinued March 2026
- Pfizer danuglipron — discontinued February 2026
A specific pattern to flag in this cross-off group: GLP-1 / obesity AI-briefs tend to lead with retatrutide results that are already public. The Lilly retatrutide remaining 7 Phase 3 readouts (TRIUMPH-2 obesity, TRIUMPH-6 maintenance, TRIUMPH-CV cardiovascular, TRANSCEND-T2D-2) are still future events — but any summary that lists “retatrutide TRIUMPH-1 in 2026” is recycling stale data and should be flagged.
Cross-cutting conference placements
These 71 catalysts don’t live in a vacuum — they cluster around the major medical meetings. Knowing where the readout will land matters for positioning.
| Conference | Date | Likely readouts |
|---|---|---|
| EASD 2026 | September | Diabetes / GLP-1 (retatrutide TRIUMPH-2 if sponsor guides it; surphodutide SYNCHRONIZE-2) |
| ESMO 2026 | October 23-27, Madrid | Oncology (camizestrant SERENA-6 OS, giredestrant competitive readout positions) |
| EADV 2026 | September 30 – October 3, Vienna | Dermatology / Immunology (Lebrikizumab pediatric, Rinvoq vitiligo, amlitelimab) |
| ACR 2026 | November 6-11, Orlando | Rheumatology / Immunology (Rinvoq AA post-marketing, Kymera KT-621) |
| AASLD 2026 | November | MASH / Liver (Madrigal resmetirion, Boehringer survodutide LIVERAGE, Akero / Novo Nordisk SYNCHRONY) |
| ASH 2026 | December, San Diego | Hematology (anito-cel myeloma, mezigdomide NDA, linvoseltamab Ph3, BeiGene sonrotoclax CELESTIAL) |
| SABCS 2026 | December, San Antonio | Breast cancer (giredestrant lidERA, evERA, BGB-16673 BTK CDAC context) |
| ASTRO 2026 | September | Radiation oncology (litelucel survival updates) |
| AAIC 2026 | July 12-15, London | Alzheimer’s (lecanemab SC, gantenerumab updates, BIIB080 tau ASO) |
| CTAD 2026 | November | Alzheimer’s, Tau (BIIB080, sabirnetug, anti-tau portfolio) |
| ECTRIMS 2026 | September / October | Multiple sclerosis (fenebrutinib filing context, frexalimab) |
| IDWeek 2026 | October | Infectious disease (Merck V116 PCV21, Moderna mRNA-1083 resubmission, Vaxcyte VAX-31) |
Conference placements matter because: data presented at SABCS (Dec) and ASH (Dec) typically gets priced in before ASCO GU (Jan-Feb), whereas ESMO data (Oct) is live-tradeable through Q4 if the readout is clean.
The Outlook Therapeutics 4th-BLA caveat
The single most important caveat in this report is ONS-5010 wet-AMD BLA, PDUFA Jul 29, 2026.
Outlook Therapeutics has resubmitted its BLA for its wet-AMD candidate four times. Each prior submission has ended in a Complete Response Letter (CRL). The historical success rate for a 4th-resubmission BLA after 3 CRLs is extremely low — usually CRLs are caused by manufacturing / inspection / CMC issues that don’t get fully resolved by a partial resubmission. The Jul 29 PDUFA is a “Class 1 review” calendar marker (2-month from resubmission), not a signal of likely approval. Treat this row as wholly speculative — if you are looking at Outlook, you are trading the CRL pattern, not the underlying data.
Leqembi SC (PDUFA Aug 24, 2026) is a more conventional caveat — the FDA extended from May 24, 2026 to Aug 24, 2026, which is sometimes a soft signal but more often is a routine additional-information request that doesn’t predict approval outcome.
What this calendar leaves off
Three categories we deliberately excluded:
- Infectious-disease platform pivots. Moderna’s mRNA-1083 flu/COVID combo BLA was pulled in May 2025 after FDA requests regarding mRNA-1010. TBD until new mRNA-1010 data unlocks resubmission.
- Pre-clinical asset readings. Anything not in active registrational trials.
- Sponsor M&A activity. Akero was acquired by Novo Nordisk in 2025 — Akero-pipeline events (e.g. SYNCHRONY Real-World interim) now track as part of Novo Nordisk’s metabolic pipeline. Acquisitions materially change the catalyst calendar.
What we will update next
Our verification pass runs weekly. Several items in this calendar have known slip risk — Boehringer survodutide LIVERAGE-1 (MASH), Roche fenebrutinib BLA acceptance date, Madrigal MAESTRO-NASH-OUTCOMES interim, Arbutus imdusiran Phase 2b hep-B functional cure data. When sponsors update guidance or conferences post acceptance schedules, we re-verify the date-tier of each row.
Notable late-cycle lookups for the next pass: Arcutis / AbbVie rinvoq pediatric data, anito-cel vs. standard ide-cel in CAR-T sequencing, BeOne BGB-16673 vs. Nx-5948 (BTK degraders, both Phase 2/3 by year-end), and the Mezigdomide NDA filing in Q4 2026 vs. an anticipated Q3 2026 surprise.
Caveats
- All primary sources are sponsor IR press releases, ClinicalTrials.gov NCT records, FDA action dates, or conference abstracts. Each event row has at least one such URL in our internal database.
- Date-precision tiers are not predictors of actual catalyst delivery — sponsors slip dates. The “Sep 30, 2026” PDUFA on Scholar Rock apitegromab is firm, but bioequivalence on a 14-day window can shift it.
- 11 events have window labels where the sponsor’s stated quarter is in Sep, 2026 (H2) format — we mapped these to “Q3 2026” but with a (H2) parenthetical preserved in the underlying data.
- We do not list mega-cap oncology events that don’t have an actionable catalyst (e.g. routine Merck PR without a PDUFA / regulatory event attached).
- Conference placements are inferred where the schedule has not been posted; final program confirmation comes typically 4-6 weeks before each meeting.
Sources
Primary source verification for the 71 events comes from these locations (sample, not exhaustive):
- Sponsor IR press releases — Lilly, Merck, BMS, Pfizer, Roche, AbbVie, AstraZeneca, Sanofi, Regeneron, Biogen, Vertex, Scholar Rock, Mineralys Therapeutics, Disc Medicine, Denali, BeiGene, Regeneron, BMS, Aurinia, Ultragenyx, Anito-cel
- ClinicalTrials.gov — primary completion dates for NCT06215716 (Akero SYNCHRONY), NCT05021835 (ZEUS), NCT06066528 (SYNCHRONIZE-2), NCT05006716 (BGB-16673 CaDAnCe-101), NCT05394116 (garetosmab OPTIMA), NCT06499285 (elritercept RENEW)
- FDA PDUFA databases and adcom schedules — multiple targeting the Aug-Dec 2026 window
- Conference programs — AAIC 2026 (Jul 12-15 London), EADV 2026 (Sep 30-Oct 3 Vienna), ESMO 2026 (Oct 23-27 Madrid), AHA 2026 (Nov), AASLD 2026 (Nov), ASH 2026 (Dec), SABCS 2026 (Dec), ACR 2026 (Nov 6-11 Orlando)
Methodology
Our internal biotech cohort tracker indexes ~4,500 public biotech and life-sciences companies. The watchlist is filtered to ~150 sponsors with disclosed late-stage assets. Each week we re-verify upcoming catalysts against primary sources, attributing each event to one of three date tiers. Items that already read out are moved to a “Already Reported” cross-off section rather than dropped, so the cross-section of cleared vs. upcoming is auditable.
This specific snapshot was prepared June 28-29, 2026 and used three parallel verification passes against the watchlist’s three therapeutic-area buckets: oncology + rare disease + hematology (19 future events), neurology + cardio + ophthalmology + pain + I&I (23 events), and metabolic + MASH + immunology + infectious (29 events).
| TA bucket | Future events | DATE / WINDOW / TBD split |
|---|---|---|
| Oncology + Rare + Heme + CF + Rare Endocrine | 19 | ~6 / 12 / 1 |
| Neurology + Cardio + Ophth + Pain + I&I | 23 | ~6 / 17 / 0 |
| Metabolic + MASH + Immuno + Infectious | 29 | ~5 / 22 / 2 |
| Total | 71 | 17 DATE, 51 WINDOW, 3 TBD |
The next refresh will adjust windows where sponsors updated guidance this week, and add 5-10 new catalysts not yet on the watchlist.
Last refresh: June 29, 2026. Cross-reference the per-event primary sources before sizing positions; precision tier is the primary axis of uncertainty, not “upcoming.”
