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 UK2, Japan3, 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 EU4 and China5 (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) (Free ASCO Whitepaper) 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) (Free ASH Whitepaper) 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 (Free ASCO Whitepaper) Annual Meeting and published in the New England Journal of Medicine.15 Updated PFS results were presented at European Hematology Association (EHA) (Free EHA Whitepaper) Congress (EHA) (Free EHA Whitepaper) 2025.

Immunotherapies have struggled to effectively treat solid tumors due to two main challenges: the lack of a tumor-specific target and the presence of an immune-suppressive tumor microenvironment. Dispatch’s first-in-class Flare platform was specifically engineered to overcome both. It works by delivering a viral vector carrying a novel, universal antigen – called Flare – that precisely tags solid tumor cells while simultaneously breaking down the tumor’s inhibitory environment. Once in place, the Flare antigen acts as a beacon, directing the immune system to find and clear the cancer cells — without harming healthy tissue.

"At Dispatch, we are leveraging the ideal tumor target – one that is only expressed by the tumor cells in a patient – and advances in cell therapy engineering and immune system activation at the right place, at the right time, to get to deep and durable responses in cancer," said Sabah Oney, Ph.D., Chief Executive Officer of Dispatch. "This work matters deeply to me, as it does to so many whose lives have been touched by cancer. We’ve built a strong scientific foundation, assembled an exceptional team and developed innovative technology that give us a real shot at making a difference. We are fully committed to doing everything we can for patients who urgently need new options."

Dispatch was established through a pivotal collaboration with the Parker Institute for Cancer Immunotherapy (PICI) and convergence of groundbreaking technologies from the laboratories of Andy Minn, M.D., Ph.D.; Carl June, M.D.; Chris Garcia, Ph.D.; and Kole Roybal, Ph.D.

"With this confluence of innovative technologies from the labs across PICI, we are poised to shift how cancer therapies are conceived," said Sean Parker, founder and chairman of PICI, as well as a member of Dispatch’s board of directors. "We can now pursue the ultimate goal – a universal cure for most solid tumor cancers – using cutting-edge modalities."

The Breakthrough Therapy Designation is based on data from the Phase 1 RMC-6291-001 clinical trial evaluating elironrasib monotherapy in patients with advanced KRAS G12C solid tumors. Results from the trial have demonstrated highly competitive antitumor activity, including differentiated safety and tolerability along with a compelling objective response rate and progression-free survival.

"There continues to be a need for new targeted therapies for patients with RAS-addicted cancers, and this Breakthrough Therapy Designation from the FDA highlights the therapeutic potential of elironrasib, a differentiated inhibitor, for patients with KRAS G12C lung cancer," said Mark A. Goldsmith M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "Coming shortly after daraxonrasib was granted a designation for patients with advanced RAS mutant pancreatic cancer, this designation for elironrasib further validates our innovative product engine as a source for novel potential treatment approaches for patients with RAS mutant cancers."

Elironrasib is an innovative inhibitor that binds selectively and covalently to the oncogenic RAS(ON) form of the RAS G12C variant that drives approximately 12% of cases of NSCLC. Revolution Medicines is exploring elironrasib monotherapy and combinations in various treatment settings and continues work to prioritize multiple options for advancing its development.

NSCLC accounts for 80%-85% of all lung cancers, and most patients have advanced or metastatic disease at initial diagnosis.1,2 KRAS mutations are found in nearly 30% of NSCLC cases, among which KRAS G12C is the most common. Currently there are no RAS-targeted inhibitors with full approval by the FDA to treat patients with KRAS G12C NSCLC.3

Breakthrough Therapy Designation is intended to expedite the development and review of potential new medicines designed to treat serious conditions and address significant unmet medical needs. Pursuant to FDA guidelines, the medicine needs to have shown encouraging preliminary clinical evidence that demonstrates substantial improvement on a clinically significant endpoint over available medicines.

About Non-Small Cell Lung Cancer
More than 197,000 people are diagnosed with non-small cell lung cancer (NSCLC) in the U.S. each year.4 Despite treatment advancements, NSCLC remains a leading cause of cancer-related mortality worldwide, primarily due to its late-stage diagnosis and limited response to conventional therapies.
