Multiple Myeloma Clinical Trial

Assessment of AMG 420 in Subjects With Relapsed and/or Refractory Multiple Myeloma

Summary

To confirm the maximum tolerated dose (MTD) from the BI 836909 trial of 400 mcg/d, given as 28-day continuous intravenous infusion in patients with relapsed and/or refractory multiple myeloma, to test the 600 mcg/d dose, given as a 28-day continuous iV infusion.

Full Description

Cohort 1 will consist of 10 subjects dosed at 400 mcg/d. Cohort 2 will consist of 10 subjects dosed at 600 mcg/d. All doses will be given as a 28-day continuous IV infusion, followed by a 2 week treatment-free interval, until subject experiences disease progression as per International Myeloma Working Group (IMWG) criteria.

Eligibility Criteria

Key Inclusion Criteria:

Pathologically-documented diagnosis of multiple myeloma that is relapsed or is refractory as defined by the following: Relapsed after 3 or more lines of prior therapy that must include a proteasome inhibitors (PI), an immunomodulators (IMiD), and a CD38-directed monoclonal antibody in any order during the course of treatment OR refractory to a PI, IMiD, and CD38-directed monoclonal antibody.

-Measurable disease, defined by 1 or more of the following at time of screening: 1) serum M-protein > 0.5 g/dL measured by serum protein electrophoresis (SPEP); 2) urinary M-protein excretion > 200 mg/24 hours; 3) Involved serum free light chain (sFLC ) measurement > 10 mg/dL, provided that the sFLC ratio is abnormal (<0.26 or >1.65) as per IMWG response criteria

Clinically not-controlled chronic or ongoing infectious disease requiring treatment at the time of study day 1 or within the 14 days before study day 1
Symptomatic peripheral sensory or motor neuropathy of grade ≥3
History or presence of clinically relevant central nervous system (CNS) pathology as uncontrolled epilepsy or seizure disorder, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, and psychosis
Active hepatitis B and C based on the following results: a) Positive for HepBsAg; b) Negative HepBsAg and positive for hepatitis B core antibody; c) Positive Hepatitis C virus antibody (HepCAb)
Known or suspected HIV infection or subjects who are HIV seropositive
Baseline ECG QTc > 470 msec (applying Fridericia correction)
Previously received an allogeneic stem cell transplant and the occurrence of 1 or more of the following: a) received the transplant within 6 months prior to study day 1; b) received immunosuppressive therapy within the last 3 months prior to study day 1; c) any active acute graft versus host disease (GvHD), grade 2 to 4, according to the Glucksberg criteria or active chronic GvHD requiring systemic treatment; d) any systemic therapy against GvHD within 2 weeks prior to start of investigational product treatment
Autologous stem cell transplantation < 90 days prior to study day 1
Treatment with systemic immune modulators including, but not limited to, nontopical systemic corticosteroids (unless the dose is ≤ 10 mg/day prednisone or equivalent), cyclosporine, and tacrolimus within 2 weeks before study day 1
Last anticancer treatment < 2 weeks prior to study day 1
Last treatment with a therapeutic antibody less than 4 weeks prior to study day 1
Systemic radiation therapy within 28 days prior to study day 1. Focal radiotherapy within 14 days prior to study day 1.
Major surgery defined as surgery requiring general anesthesia with endotracheal intubation within 28 days prior to study day 1, unless discussed with and eligibility approved by Amgen medical monitor
Prior treatment with any drug that specifically targets BCMA on tumor cells (eg, other bi-specific antibody constructs, antibody drug conjugates, or CAR T-cells, except for subjects who were previously treated with AMG 420 in this study and who are candidates for second-course treatment
