Rhea-AI Filing Summary

GSK plc received approval in China for Blenrep (belantamab mafodotin) in combination with bortezomib and dexamethasone to treat adults with relapsed or refractory multiple myeloma after at least one prior therapy.

The decision by China’s National Medical Products Administration followed priority review and Breakthrough Therapy Designation for the regimen. It is the only anti-BCMA option approved in second line and beyond multiple myeloma in China, and the only fully outpatient anti-BCMA therapy, allowing 30-minute infusions without hospitalisation.

The DREAMM-7 phase III trial showed the Blenrep combination nearly tripled median progression-free survival to 36.6 months versus 13.4 months for a daratumumab-based triplet, and reduced the risk of death by 42%. Three-year overall survival was 74% for the Blenrep regimen versus 60% for the comparator, with safety broadly consistent with known profiles and manageable eye-related side effects.

Positive

  • China regulatory approval in 2L+ multiple myeloma – NMPA clearance for Blenrep plus bortezomib and dexamethasone opens a large new market in an earlier treatment setting, backed by priority review and Breakthrough Therapy Designation.
  • Strong phase III efficacy versus a daratumumab-based regimen – DREAMM-7 showed median progression-free survival of 36.6 months vs 13.4 months and a 42% reduction in risk of death, with higher three-year overall survival.
  • Outpatient-friendly anti-BCMA ADC profile – Blenrep is described as the only fully outpatient anti-BCMA therapy, delivered as a 30-minute infusion, which may improve practicality in community oncology settings.

Negative

  • None.

Insights

China approval adds a meaningful new market for Blenrep with strong phase III data.

The approval of Blenrep plus bortezomib and dexamethasone in China moves the drug into earlier treatment lines for relapsed or refractory multiple myeloma. It follows priority review and Breakthrough Therapy Designation, underscoring perceived clinical benefit over existing options.

DREAMM-7 results are robust: median progression-free survival reached 36.6 months versus 13.4 months with a daratumumab-based regimen, and the regimen cut risk of death by 42%. Three-year overall survival of 74% versus 60% supports durable benefit.

Commercially, China’s multiple myeloma incidence is about 30,000 new cases annually, and Blenrep is positioned as the only anti-BCMA antibody-drug conjugate with fully outpatient 30-minute infusions. Actual uptake will depend on access, reimbursement and how clinicians balance efficacy with manageable eye-related toxicity described in the trial.

progression-free survival (PFS) medical
"These include statistically significant and clinically meaningful progression-free survival (PFS) and overall survival (OS) results"
Progression-free survival (PFS) measures the length of time in a clinical trial or treatment period during which a patient’s disease does not get worse. Investors watch PFS because longer PFS in trials can signal a drug’s effectiveness, influence regulatory approval and reimbursement decisions, and affect commercial value—think of it as how long a product keeps a problem from returning, which helps estimate future sales and competitive advantage.
overall survival (OS) medical
"statistically significant and clinically meaningful progression-free survival (PFS) and overall survival (OS) results for the Blenrep combination"
Overall survival (OS) is the length of time from the start of a treatment or clinical study until death from any cause, essentially measuring how long patients live after a therapy begins. Investors watch OS because it is the most direct evidence a treatment extends life; stronger OS results can drive regulatory approvals, wider use and higher revenue expectations, much like sales figures proving a product actually works.
antibody-drug conjugate (ADC) medical
"Blenrep is the only anti-BCMA (B-cell maturation antigen) antibody-drug conjugate (ADC) approved in multiple myeloma"
An antibody-drug conjugate (ADC) is a targeted medical treatment that combines an antibody, which acts like a guided missile seeking out specific cells, with a powerful drug to destroy those cells. It is designed to deliver medication directly to diseased cells, minimizing damage to healthy tissue. For investors, ADCs represent innovative therapies with potential for high growth, especially if they prove effective in treating difficult-to-cure conditions.
B-cell maturation antigen (BCMA) medical
"Blenrep is the only anti-BCMA (B-cell maturation antigen) antibody-drug conjugate (ADC) approved in multiple myeloma"
Breakthrough Therapy Designation regulatory
"The approval follows priority review of the application and Breakthrough Therapy Designation for the BVd combination"
A breakthrough therapy designation is a regulatory fast-track given to a drug or treatment that shows early signs of providing a major improvement over existing options for a serious condition. Think of it as a VIP lane that can speed up development and more intensive guidance from regulators, which matters to investors because it can shorten time to market, reduce development risk and potentially increase a company’s value — though it does not guarantee approval.
priority review regulatory
"The approval follows priority review of the application and Breakthrough Therapy Designation for the BVd combination"
Priority review is a regulatory fast-track that shortens the time an agency spends evaluating a drug, vaccine or medical device application so a decision comes sooner than normal. For investors, it matters because a faster review is like an express lane to market: it can speed revenue potential and reduce regulatory uncertainty, but it does not guarantee approval and still requires the product to meet safety and effectiveness standards.

Blenrep (belantamab mafodotin) approved in China for treatment of 2L+ relapsed/refractory multiple myeloma
 
●     Blenrep combination showed a 42% reduction in risk of death and nearly tripled median progression-free survival versus a daratumumab-based triplet[1],[2]
●     As the only anti-BCMA approved in 2L+ multiple myeloma in China, Blenrep provides a new and needed mechanism of action in therapy1,[3]
●     Blenrep is the only fully outpatient anti-BCMA therapy, minimising patient and healthcare burden[4]
 
 
GSK plc (LSE/NYSE: GSK) today announced the National Medical Products Administration (NMPA) of China has approved Blenrep (belantamab mafodotin) in combination with bortezomib and dexamethasone (BVd) for the treatment of adults with relapsed or refractory multiple myeloma who have received at least one prior line of therapy. The approval follows priority review[5] of the application and Breakthrough Therapy Designation[6] for the BVd combination based on its potential to provide substantial improvement over available therapies.[7]
 
The Blenrep approval is supported by data from the pivotal DREAMM-7 phase III trial. These include statistically significant and clinically meaningful progression-free survival (PFS) and overall survival (OS) results for the Blenrep combination versus a daratumumab-based triplet combination with bortezomib and dexamethasone (DVd). The safety and tolerability profiles of the Blenrep combination were broadly consistent with the known profiles of the individual agents.1,2
 
Hesham Abdullah, Senior Vice President, Global Head Oncology, R&D, GSK, said: "Patients with multiple myeloma who face relapse need treatment options that are both effective and accessible. Today's approval of Blenrep brings anti-BCMA therapy to patients in China with relapsed or refractory multiple myeloma in 2L+, introducing a differentiated mechanism of action with the potential to help slow disease progression and extend survival. Further, Blenrep as the only anti-BCMA ADC is fully outpatient administered, so patients can be treated at any site of care without complex pre-administration regimens or hospitalisation."
 
In China, the incidence of multiple myeloma has doubled to approximately 30,000 new cases annually and mortality has increased by 50% over the past three decades.[8] Blenrep is the only anti-BCMA (B-cell maturation antigen) antibody-drug conjugate (ADC) approved in multiple myeloma, which provides patients with a differentiated mechanism of action. Blenrep can be administered to a range of patient types across treatment settings as a 30-minute outpatient infusion. 
 
About multiple myeloma
Multiple myeloma is the third most common blood cancer globally and is generally considered treatable but not curable.[9],[10] There are approximately 180,000 new cases of multiple myeloma diagnosed globally each year.[11] Research into new therapies is needed as multiple myeloma commonly becomes refractory to available treatments.3 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.[12],[13]
 
About Blenrep
Blenrep is a monoclonal ADC comprising a humanised BCMA conjugated to the cytotoxic agent monomethyl 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.
 
Blenrep is approved in the US[14] in combination with bortezomib plus dexamethasone for the treatment of adults who have previously received at least two prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent. Blenrep has received more than 15 regulatory approvals in 2L+ relapsed or refractory multiple myeloma in combination with bortezomib and dexamethasone and in combination with pomalidomide and dexamethasone, including in the European Union[15], UK[16], Japan[17], Canada, Switzerland, Brazil and Australia. Applications are under review in other countries globally.

About DREAMM-7
DREAMM-7 is a multicentre, open-label, randomised phase III clinical trial evaluating the efficacy and safety of BVd compared to 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 2.5mg/kg intravenously every three weeks in combination for the first eight cycles and then continued as a single agent. The primary endpoint was PFS as per an independent review committee, with secondary endpoints including 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 overall, 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.2
 
In DREAMM-7, BVd consistently benefited a broad range of patients, including those with poor prognostic features or outcomes, such as high-risk cytogenetics or those refractory to lenalidomide. The trial also showed clinically meaningful improvements across all other secondary efficacy endpoints, including deeper and more durable responses versus the comparator.2
 
DREAMM-7 showed that eye-related side effects associated with Blenrep can be managed and reversed with appropriate dose modifications and follow-up. This allowed patients to maintain benefit and resulted in low rates of discontinuation due to eye-related side effects (≤9%). The most commonly reported non-ocular adverse events (>30% of participants) in the Blenrep combination arm were thrombocytopenia (87%) and diarrhoea (32%) in DREAMM-7.2
 
PFS results[19] were presented at the American Society of Clinical Oncology (ASCO) Plenary Series in February 2024 and published in the New England Journal of MedicineOS results[20] were presented at the American Society of Hematology (ASH) Annual Meeting in December 2024.

FAQ

What did GSK (GSK) announce about Blenrep in China?

GSK announced that China’s NMPA approved Blenrep with bortezomib and dexamethasone for adults with relapsed or refractory multiple myeloma after at least one prior therapy. The regimen received priority review and Breakthrough Therapy Designation based on phase III DREAMM-7 data.

How effective was GSK’s Blenrep regimen in the DREAMM-7 trial?

In DREAMM-7, Blenrep plus bortezomib and dexamethasone nearly tripled median progression-free survival to 36.6 months versus 13.4 months for a daratumumab-based regimen. It also reduced the risk of death by 42% and improved three-year overall survival to 74% versus 60%.

What makes Blenrep unique among multiple myeloma treatments in China?

Blenrep is described as the only anti-BCMA therapy approved in second line and later multiple myeloma in China and the only fully outpatient anti-BCMA option. It is an antibody-drug conjugate given as a 30-minute infusion, aiming to minimise patient and healthcare burden.

What patient population is targeted by GSK’s Blenrep approval in China?

The approval covers adults with relapsed or refractory multiple myeloma who have received at least one prior line of therapy. These patients typically have disease that has returned or stopped responding to earlier treatments, creating demand for effective, accessible second-line options.

What safety profile was seen with Blenrep in the DREAMM-7 study?

In DREAMM-7, Blenrep’s safety and tolerability were broadly consistent with the known profiles of its components. Eye-related side effects were manageable and reversible with dose adjustments, leading to discontinuation rates of 9% or less. Common non-ocular events included thrombocytopenia and diarrhoea.

How large is the multiple myeloma burden in China mentioned by GSK?

GSK cited research estimating around 30,000 new multiple myeloma cases annually in China, with mortality rising 50% over three decades. This growing disease burden highlights the clinical need for new therapies such as Blenrep-based regimens in relapsed or refractory settings.
