BLENREP safety

BLENREP has a generally manageable safety profile1

For GB healthcare professionals only.*

Table of contents

In the final analysis of the DREAMM-2 trial, BLENREP (administered as 2.5 mg/kg every 3 weeks) delivered an overall response rate of 32% (n=31/97; 95% CI 21.7-43.6) in triple-refractory patients with multiple myeloma. 58% (n=18) of responding patients achieved a ≥VGPR. Responses to BLENREP were fast, deep and durable.2


DREAMM-2 safety summary (n=95)

BLENREP is generally well-tolerated with a manageable safety profile. 12% (n=11) of patients discontinued treatment permanently due to adverse events.2

    Blurred vision includes the preferred terms vision blurred, diplopia, visual acuity reduced, and visual impairment.

Eye-related side effects associated with BLENREP were manageable and generally resolved over time1,2

Median time to resolution of first event of BCVA reduction to 20/50 or worse at final analysis (range 50-103 days)2


of patients (n=5/95) discontinued treatment due to eye-related side effects†2

Discontinuation included one patient with keratopathy, one patient with blurred vision, and one patient with reduced visual acuity.2
Recovery is defined as resolution or return to baseline. DREAMM-2 13-month follow up.

*Duration defined as time from onset of any keratopathy event to first time subject is free from event.
Resolution defined as having a post-baseline score ≥20/50 or no equivalent value in either eye.
A gap of ≥1 day was required between resolution of first and occurrence of second event.

BLENREP AEs can be managed through dose delays and modifications, whilst continuing to provide sustained efficacy3

Learn more about how to manage side effects with dose modifications, so you can keep your patients on treatment.

Effect on disease symptoms and health-related QoL

With BLENREP, there was no change in overall patient-reported Global Health Status/QoL, Physical Functioning, or Role Functioning domain scores of the EORTC-QLQ-C30 at the final readout. This included patients with a minimal meaningful withinpatient reduction in vision-related function by Ocular Surface Disease Index (OSDI).3

BL, baseline; EORTC-QLQ-C30, European Organisation for Research and Treatment of cancer quality of life questionnaire; OSDI, Ocular Surface Disease Index; QoL, quality of life.

The European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC-QLQ-C30) is a 30 item, cancerspecific measure of global health-related quality of life. The Ocular Surface Disease Index (OSDI) is an ophthalmic vision–related PRO questionnaire used to characterise the impact of corneal events on patient symptoms and visual function. In DREAMM-2, patients completed PRO questionnaires electronically at baseline and Q3W during treatment.

BLENREP is indicated as monotherapy for the treatment of multiple myeloma in adult patients, who have received at least four prior therapies and whose disease is refractory to at least one proteasome inhibitor, one immunomodulatory agent, and an anti-CD38 monoclonal antibody, and who have demonstrated disease progression on the last therapy.1
