A Multicenter Expanded Access Program Protocol for Melphalan Flufenamide (melflufen) in Combination with Dexamethasone in Patients with Triple Class Refractory (TCR) Multiple Myeloma(MM) NCT04534322
Melphalan Flufenamide is an investigational agent and not currently approved by the US FDA.
An open label single arm multicenter expanded access treatment protocol with melflufen and dexamethasone for patients with:
- A clinically confirmed prior diagnosis of multiple myeloma with documented disease progression.
- Triple-class refractory multiple myeloma (TCR MM).
Triple-class refractory defined as refractory to at least one PI, at least one IMiD, and at least one Anti-CD38 mAb.
- Patients (with non-primary refractory MM) are required to have a minimum of at least 2 prior lines of therapy.
- Patients with primary refractory MM are eligible if they meet the criteria for TCR MM. They may meet these criteria for TCR MM if they have received at least one PI, at least one IMiD, and at least one Anti-CD38 mAb in their first line treatment or have had at least 2 prior lines of therapy.1
sEAPort is currently open for enrollment.2
To provide early access to melflufen treatment for eligible patients before commercial approval.
To evaluate safety and tolerability data of melflufen in combination with dexamethasone.
Secondary Objectives (Recommended / Optional):
To evaluate activity in patients treated with melflufen in combination with dexamethasone, by physician assessment.
Other optional assessments will also include collection of patient reported outcomes (PRO).
