BLENREP safety

BLENREP has a generally manageable safety profile1

For GB healthcare professionals only.*

Table of contents

In the 13-month follow-up 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. Responses to BLENREP were fast, deep and durable.2


DREAMM-2 safety summary (n=95)

*Clinically meaningful best corrected visual acuity (BCVA) change represents a BCVA of Snellen Visual Acuity 20/50 or worse in the better-seeing eye.2

BLENREP is generally well-tolerated with a manageable safety profile:1

  • 9% (n=9) of patients permanently discontinued treatment because of AEs
  • There were no reports of cytokine release syndrome and 7% (n=7) of patients experienced Grade ≥3 infections with BLENREP

*Clinically meaningful BCVA change represents a BCVA of Snellen Visual Acuity 20/50 or worse in the better-seeing eye.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.

BLENREP AEs can be managed through dose delays and modifications, whilst continuing to provide sustained efficacy2

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


Collaborate with eye care professionals* to effectively monitor for eye-related side effects1

Utilise the ‘3 Ms management plan’ for eye-related side effects:1

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 13 month follow up (cut-off date 31 Jan 2020). This included patients with a minimal meaningful withinpatient reduction in vision-related function by Ocular Surface Disease Index (OSDI).3

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 not commercially available in Northern Ireland.

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
