Rhea-AI Filing Summary

Key event: The FDA has extended the Biologics License Application review for GSK’s Blenrep (belantamab mafodotin) combinations in relapsed/refractory multiple myeloma, setting a new PDUFA action date of 23 October 2025—roughly three months later than previously expected.

Clinical support: The filing is underpinned by Phase III DREAMM-7 and DREAMM-8 data. DREAMM-7 nearly tripled median progression-free survival (36.6 m vs 13.4 m; HR 0.41, p<0.00001) and cut death risk by 42% (HR 0.58). DREAMM-8 showed a median PFS of 32.6 m vs 12.5 m (HR 0.49) with benefit across high-risk subgroups; overall-survival trend is positive but not yet significant.

Regulatory landscape: Blenrep combos are already approved in the UK, Japan, Canada, Switzerland and UAE, with ongoing reviews in the EU, China and other major markets.

Investor takeaway: While the three-month US delay defers potential revenue into late-2025, the robust efficacy profile remains intact, and GSK continues constructive FDA engagement.

Evento chiave: La FDA ha prorogato la revisione della Biologics License Application per le combinazioni di Blenrep (belantamab mafodotin) di GSK nel mieloma multiplo recidivante/refrattario, fissando una nuova data di azione PDUFA al 23 ottobre 2025, circa tre mesi oltre la precedente previsione.

Supporto clinico: La domanda si basa sui dati di fase III degli studi DREAMM-7 e DREAMM-8. DREAMM-7 ha quasi triplicato la sopravvivenza libera da progressione mediana (36,6 mesi vs 13,4 mesi; HR 0,41, p<0,00001) e ridotto il rischio di morte del 42% (HR 0,58). DREAMM-8 ha mostrato una PFS mediana di 32,6 mesi contro 12,5 mesi (HR 0,49) con benefici evidenti anche nei sottogruppi ad alto rischio; la tendenza alla sopravvivenza globale è positiva ma non ancora significativa.

Scenario regolatorio: Le combinazioni di Blenrep sono già approvate nel Regno Unito, Giappone, Canada, Svizzera e UAE, con revisioni in corso nell’UE, Cina e altri mercati principali.

Considerazioni per gli investitori: Sebbene il ritardo di tre mesi negli USA posticipi i potenziali ricavi alla fine del 2025, il profilo di efficacia rimane solido e GSK mantiene un dialogo costruttivo con la FDA.

Evento clave: La FDA ha extendido la revisión de la Solicitud de Licencia Biológica para las combinaciones de Blenrep (belantamab mafodotin) de GSK en mieloma múltiple recidivante/refractario, estableciendo una nueva fecha de acción PDUFA para el 23 de octubre de 2025, aproximadamente tres meses más tarde de lo previsto.

Apoyo clínico: La solicitud se basa en datos de fase III de los estudios DREAMM-7 y DREAMM-8. DREAMM-7 casi triplicó la mediana de supervivencia libre de progresión (36,6 meses vs 13,4 meses; HR 0,41, p<0,00001) y redujo el riesgo de muerte en un 42% (HR 0,58). DREAMM-8 mostró una mediana de SLP de 32,6 meses frente a 12,5 meses (HR 0,49) con beneficios en subgrupos de alto riesgo; la tendencia de supervivencia global es positiva pero aún no significativa.

Panorama regulatorio: Las combinaciones de Blenrep ya están aprobadas en Reino Unido, Japón, Canadá, Suiza y Emiratos Árabes Unidos, con revisiones en curso en la UE, China y otros mercados importantes.

Conclusión para inversores: Aunque el retraso de tres meses en EE.UU. pospone posibles ingresos hasta finales de 2025, el perfil de eficacia robusto permanece intacto y GSK mantiene un compromiso constructivo con la FDA.

Contexte réglementaire : Les combinaisons de Blenrep sont déjà approuvées au Royaume-Uni, au Japon, au Canada, en Suisse et aux Émirats arabes unis, avec des examens en cours dans l’UE, en Chine et d’autres marchés majeurs.

Message aux investisseurs : Bien que ce retard de trois mois aux États-Unis repousse les revenus potentiels à la fin 2025, le profil d’efficacité robuste reste intact et GSK poursuit un dialogue constructif avec la FDA.

ü𾱲Ծ: Die FDA hat die Prüfung des Biologics License Application für GSKs Blenrep (Belantamab Mafodotin) Kombinationen bei rezidiviertem/refraktärem Multiplen Myelom verlängert und ein neues PDUFA-Aktionsdatum auf den 23. Oktober 2025 festgelegt � etwa drei Monate später als zuvor erwartet.

Klinische Unterstützung: Die Einreichung stützt sich auf Phase-III-Daten der Studien DREAMM-7 und DREAMM-8. DREAMM-7 verdreifachte nahezu das mediane progressionsfreie Überleben (36,6 Monate vs. 13,4 Monate; HR 0,41, p<0,00001) und senkte das Sterberisiko um 42 % (HR 0,58). DREAMM-8 zeigte ein medianes PFS von 32,6 Monaten gegenüber 12,5 Monaten (HR 0,49) mit Vorteilen in Hochrisikogruppen; der Trend beim Gesamtüberleben ist positiv, aber noch nicht signifikant.

Regulatorische Lage: Blenrep-Kombinationen sind bereits im Vereinigten Königreich, Japan, Kanada, der Schweiz und den VAE zugelassen, mit laufenden Prüfungen in der EU, China und weiteren wichtigen Märkten.

Fazit für Investoren: Obwohl die dreimonatige Verzögerung in den USA potenzielle Einnahmen auf Ende 2025 verschiebt, bleibt das robuste Wirksamkeitsprofil erhalten, und GSK pflegt weiterhin einen konstruktiven Dialog mit der FDA.

Positive
  • Phase III superiority: DREAMM-7 nearly tripled PFS and cut OS risk by 42%, indicating strong competitive positioning.
  • Global traction: Approvals in five countries and positive CHMP opinion broaden early revenue base ahead of US launch.
Negative
  • PDUFA delay: FDA pushed decision to 23 Oct 2025, deferring potential US revenue and raising regulatory uncertainty.
  • Label risk: Known ocular toxicity could lead to REMS or usage restrictions, impacting market uptake.

Insights

TL;DR: 3-month FDA delay is modest; strong Phase III data still supports sizeable 2026 revenue ramp.

The PDUFA push to 23 Oct 2025 postpones first US sales, likely shifting revenue recognition by one fiscal quarter. However, DREAMM-7’s 36.6-month PFS and 42% OS risk reduction substantially exceed current triplet standards, reinforcing blockbuster potential. Global approvals and positive CHMP opinion de-risk ex-US forecasts. Valuation impact should be limited; maintain focus on manufacturing readiness and ocular-toxicity management for label discussions.

TL;DR: FDA extension signals information gap, but no new safety flag; overall outlook unchanged.

Routine extensions often arise from late-cycle data submissions; the agency requested extra time, not additional trials. Safety profiles in DREAMM-7/8 match known belantamab risks (corneal events), suggesting review complexity rather than efficacy doubt. Investors should watch for potential REMS requirements that could narrow the commercial population. Still, Breakthrough status in China and multiple global nods indicate regulatory momentum.

GSK announces extension of US Food and Drug Administration review period for Blenrep (belantamab mafodotin-blmf) in relapsed/refractory multiple myeloma
 
●    New PDUFA date scheduled for 23 October 2025
 
 
 
GSK plc (LSE/NYSE: GSK) today announced the US Food and Drug Administration (FDA) has extended the review period for the Biologics License Application (BLA) for Blenrep combinations[1] for the treatment of patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy. The new Prescription Drug User Fee Act (PDUFA) action date is 23 October 2025 and provides the FDA with time to review additional information provided in support of the application.
 
The BLA is supported by efficacy results shown by Blenrep combinations in the pivotal DREAMM-7 and DREAMM-8 phase III trials in relapsed or refractory multiple myeloma. These include statistically significant and clinically meaningful progression-free survival results for Blenrep combinations versus triplet standard of care combinations in both trials and overall survival versus a daratumumab-based triplet in DREAMM-7. The safety and tolerability profiles of the Blenrep combinations were broadly consistent with the known profiles of the individual agents.
 
GSK is confident in the data supporting Blenrep combinations and looks forward to ongoing constructive conversations with the FDA as they continue their review.
 
Blenrep combinations are currently approved in the UK[2], Japan[3], Canada, Switzerland (DREAMM-8 only at this time) and the United Arab Emirates. Applications are currently under review in all major markets globally, including the EU[4] and China[5] (based on the results of DREAMM-7, with Breakthrough Therapy Designation for the combination and priority review for the application).
 
About multiple myeloma
Multiple myeloma is the third most common blood cancer globally and is generally considered treatable but not curable.[6],[7] There are approximately more than 180,000 new cases of multiple myeloma diagnosed globally each year.[8] Research into new therapies is needed as multiple myeloma commonly becomes refractory to available treatments.[9] Many patients with multiple myeloma are treated in a community cancer setting, leaving an urgent need for new, effective therapies with manageable side effects that can be administered outside of an academic centre.[10],[11]
 
About Blenrep
Blenrep is an ADC comprising a humanised BCMA monoclonal antibody conjugated to the cytotoxic agent auristatin F via a non-cleavable linker. The drug linker technology is licensed from Seagen Inc.; the monoclonal antibody is produced using POTELLIGENT Technology licensed from BioWa Inc., a member of the Kyowa Kirin Group.
 
Indication
Blenrep combinations were approved in relapsed or refractory multiple myeloma in the UK in April 2025.
 
In the UK, Blenrep is indicated in adults for the treatment of multiple myeloma:
 
●  in combination with bortezomib and dexamethasone in patients who have received at least one prior therapy; and
 
●  in combination with pomalidomide and dexamethasone in patients who have received at least one prior therapy including lenalidomide.
 
IMPORTANT SAFETY INFORMATION FOR BLENREP
More information can be found in the Blenrep Summary of Product Characteristics and Patient Information leaflets available on the MHRA Products website.[12]
 
About DREAMM-7
DREAMM-7 is a multicentre, open-label, randomised phase III clinical trial evaluating the efficacy and safety of belantamab mafodotin combined with bortezomib plus dexamethasone (BVd) compared to daratumumab combined with bortezomib plus dexamethasone (DVd) in patients with relapsed or refractory multiple myeloma who previously were treated with at least one prior line of multiple myeloma therapy, with documented disease progression during or after their most recent therapy. The trial enrolled 494 participants who were randomised 1:1 to receive either BVd or DVd. Belantamab mafodotin was administered at a dose of 2.5 mg/kg intravenously every three weeks in combination for the first eight cycles and then continued as a single agent. The primary endpoint was progression-free survival (PFS) as per an independent review committee, with secondary endpoints including overall survival (OS), duration of response (DOR), and minimal residual disease (MRD) negativity rate as assessed by next-generation sequencing. Other secondary endpoints include overall response rate (ORR), safety, and patient reported and quality of life outcomes.
 
In DREAMM-7, BVd nearly tripled median PFS versus DVd (36.6 months versus 13.4 months, respectively (hazard ratio [HR]: 0.41 [95% confidence interval (CI): 0.31-0.53], p-value<0.00001). DREAMM-7 also met the key secondary endpoint of OS, showing a statistically significant and clinically meaningful 42% reduction in the risk of death at a median follow-up of 39.4 months favouring BVd (n=243) versus DVd (n=251) (HR 0.58; 95% CI: 0.43-0.79; p=0.00023). The three-year OS rate was 74% in the BVd arm and 60% in the DVd arm.
 
PFS results were presented at the American Society of Clinical Oncology (ASCO) Plenary Series in February 2024 and published in the New England Journal of Medicine. OS results were presented at the American Society of Hematology (ASH) Annual Meeting in December 2024.[13],[14]
 
About DREAMM-8
DREAMM-8 is a multicentre, open-label, randomised phase III clinical trial evaluating the efficacy and safety of belantamab mafodotin in combination with pomalidomide plus dexamethasone (BPd) compared to bortezomib and pomalidomide plus dexamethasone (PVd) in patients with relapsed or refractory multiple myeloma previously treated with at least one prior line of multiple myeloma therapy, including a lenalidomide-containing regimen, and who have documented disease progression during or after their most recent therapy. The trial included 302 participants who were randomised 1:1 to receive either BPd or PVd. Compared to the patient population studied in the DREAMM-7 trial, patients in DREAMM-8 were more heavily pre-treated in that all had prior exposure to lenalidomide, 78% were refractory to lenalidomide, 25% had prior daratumumab exposure and of those most were daratumumab refractory. Belantamab mafodotin was administered at a dose of 2.5 mg/kg intravenously for the first cycle and then 1.9 mg/kg intravenously every four weeks. The primary endpoint was PFS as per an independent review committee, with key secondary endpoints including OS and MRD negativity rate as assessed by next-generation sequencing. Other secondary endpoints include ORR, DOR, safety, and patient reported and quality of life outcomes.
 
At the primary analysis at a median follow-up of 21.8 months, the median PFS was not yet reached (95% CI: 20.6-not yet reached [NR]) with the Blenrep combination compared to 12.7 months in the bortezomib combination (95% CI: 9.1-18.5). A positive OS trend was observed but not statistically significant (HR: 0.77 [95% CI: 0.53-1.14]) at the interim analysis. OS follow-up continues and further analyses are planned. 
 
With additional follow-up, a clinically meaningful benefit continued to be observed, with a near-tripling of the median PFS for the Blenrep combination versus the bortezomib combination (32.6 months versus 12.5 months, respectively (HR: 0.49 [95% CI: 0.35-0.68]). At the end of one year, 71% (95% CI: 63-78) of patients in the BPd combination group compared to 51% (95% CI: 42-60) in the PVd combination group were alive and had not progressed. A benefit for BPd was observed across all pre-specified subgroups including those with poor prognostic features, such as patients who were refractory to lenalidomide and patients with high-risk cytogenetics.
 
Results were first presented at the 2024 ASCO Annual Meeting and published in the New England Journal of Medicine.[15] Updated PFS results were presented at European Hematology Association Congress (EHA) 2025.[16]

FAQ

Why did the FDA extend GSK’s Blenrep PDUFA date to 23 October 2025?

The agency requested additional time to review new information submitted with the BLA; no new trials were mandated.

How effective were Blenrep combinations in the DREAMM-7 trial?

Median PFS was 36.6 months vs 13.4 months for the comparator (HR 0.41); OS risk fell by 42%.

Which countries have already approved Blenrep combinations?

Approvals exist in the UK, Japan, Canada, Switzerland and UAE, with EU and China reviews ongoing.

Will the FDA delay materially affect GSK’s 2025 earnings?

It likely shifts US revenue by one fiscal quarter; impact on full-year 2025 guidance depends on launch timing.

What safety concerns are associated with Blenrep?

The main issue is ocular toxicity (corneal events); FDA may impose monitoring or REMS requirements.
