News release: Exciting news for DLBCL Patients: A New Treatment Option Registered!

Exciting News for DLBCL Patients: A New Treatment Option Registered!

On 29th May 2025, Medsafe registered a new treatment combination: Columvi® (glofitamab) plus chemotherapy (GemOx) in New Zealand. This registration means that adults whose diffuse large B-cell lymphoma (DLBCL) has returned or did not respond to initial treatment, and who are not eligible for a stem cell transplant, will have another important treatment option in the future.1

What does "Medsafe registration" mean for you?

Before a new medicine can be made widely available, it undergoes careful review by health experts to ensure it's safe and effective. This registration from Medsafe confirms that glofitamab plus chemotherapy has met these high standards and can now be used to treat eligible NZ patients.

What did the pivotal study show?

This registration is based on the results of a clinical study called STARGLO. This study compared the new treatment combination to a standard treatment of rituximab plus chemotherapy (GemOx) in patients whose DLBCL had relapsed or was not responding to initial therapy and who were not eligible for a stem cell transplant.

The study showed that patients receiving glofitamab plus chemotherapy (GemOx) lived almost twice as long compared with those receiving the standard therapy. Furthermore, more than twice as many patients on the glofitamab combination experienced a complete disappearance of their cancer. The safety of the combination was consistent with what is already known about the individual medicines.2

Why is this important?

DLBCL is a fast-growing cancer, and if it comes back or doesn't respond to the first treatment, it's crucial to have effective options available quickly. This new glofitamab-based treatment offers an "off-the-shelf" option, meaning it can be readily available for patients without the delays associated with more complex treatments. It's also designed as a fixed-duration therapy, offering the possibility of a planned end to the treatment course and a treatment-free period afterwards. This can provide a sense of control and allow patients to plan for the future.

Looking ahead: Making this treatment accessible

We understand that access to new medicines is a significant concern for patients and their families. While we work towards securing Pharmac reimbursement for glofitamab we are actively exploring patient access solutions. Our goal is to ensure that eligible patients can benefit from this innovative treatment as soon as possible. We are committed to working closely with patient advocacy groups and healthcare providers to navigate the reimbursement process and implement effective access programs. We will share more information about this programme as soon as it becomes available.

This registration marks an important step forward in the treatment of relapsed or refractory DLBCL, offering hope for improved outcomes and a better quality of life for patients.
