Study Design
Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: ALT-803
Type: Biological
Overall Status
This is a Phase Ib/II, open-label, multi-center, competitive enrollment and dose escalation study of ALT-803 in patients with relapsed or refractory multiple myeloma.
Detailed Description
The purpose of this study is to evaluate the safety, determine the Maximum Tolerated Dose (MTD) or the Minimum Efficacious Dose (MED) and characterize the immunogenicity and pharmacokinetic profile of ALT-803 in treated patients. The effect of ALT-803 on the peripheral absolute lymphocyte counts and white blood cell counts, the number and phenotype of peripheral blood T (total and subsets) and NK cells will be evaluated. The anti-tumor responses of ALT-803 will also be assessed in this trial.

- Confirmed diagnosis of relapsed/refractory multiple myeloma after treatment with at least two different previous regimens.

- Refractory disease is defined as progressive disease while on therapy or progression within 60 days of therapy.

- Progressive disease is defined by a 25% increase from the lowest response value in specified tests.

- Measurable disease as defined by at least one of the following:

- Serum M-protein ≥ 1g/dL (for IgG, IgM) or 0.5 g/dL (for IgA)

- Serum free light chains ≥ 10 mg/dL and abnormal kappa/lambda ratio


- No anti-myeloma treatments within 28 days before the start of study treatment.

- Must have recovered from side effects of prior treatments.
