Dose exploration cohorts to estimate the MTD, safety, tolerability, and PK of different doses of AMG 562 in subjects with relapsed/refractory DLBCL, MCL or FL using a Bayesian logistic regression model (BLRM; Neuenschwander et al, 2008).

dose expansion part to gain further clinical experience, safety and efficacy data for AMG 562 in subjects with relapsed / refractory DLBCL. The dose to be evaluated will be at or below the MTD estimated in the dose exploration cohorts.

AMG 562 is a BiTE® antibody construct that targets CD19 and is intended for the treatment of patients with B-cell malignancies.

AMG 562

Evaluate the safety and tolerability of AMG 562 in adult subjects with DLBCL, MCL, or FL. Estimate the maximum tolerated dose (MTD) and/or a biologically active dose (e.g., recommended phase 2 dose \[RP2D\])

Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of AMG 562 in Subjects With r/r Diffuse Large B-cell Lymphoma, Mantle Cell Lymphoma, or Follicular Lymphoma

A Phase 1, First-in-Human, Open-Label Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Efficacy of AMG 562 in Subjects With Relapsed / Refractory Diffuse Large B-cell Lymphoma, Mantle Cell Lymphoma, or Follicular Lymphoma

An adverse event (AE) was defined as any untoward medical occurrence in a clinical trial participant. TEAEs were any AE that occurred after receiving at least 1 dose of treatment.

Treatment-related TEAEs were those considered related to study treatment by the investigator.

Disease-Related TEAEs were events (serious or non-serious) anticipated to occur in the study population due to the underlying disease.

Any clinically significant changes in vital signs, physical examinations, electrocardiograms (ECG)s and clinical laboratory tests were recorded as TEAEs.

ORR was defined as the percentage of participants with a confirmed complete metabolic response (CMR) or partial metabolic response (PMR) as defined by Lugano Classification.

Per the Lugano Classification, positron emission tomography-computed tomography (PET-CT) were defined on the 5-point scale as scores 1, 2, or 3 (where 1 = no uptake above background; 2 = uptake \</= mediastinum; and 3 = uptake \> mediastinum but \</= liver) and PET-positive scans, as scores of 4 or 5 (where 4 = uptake moderately higher than liver; 5 = uptake markedly higher than liver and/or new lesions).

CMR: score of 1, 2 or 3 in nodal or extranodal sites with or without a residual mass.

PMR: score of 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size.

CMR: score of 1, 2 or 3 in nodal or extranodal sites with or without a residual mass.

PMR: score of 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size.

No metabolic response (NMR): score of 4 or 5 with no obvious change in fluorodeoxyglucose (FDG) uptake.

Progressive metabolic disease (PMD): score 4 or 5 in any lesion with an increase in intensity of FDG uptake from baseline (and/or new FDG-avid foci consistent with lymphoma).

DOR was defined as the time from the date of an initial objective response per Lugano classification to the earlier of progression or death. Participants who had not ended their response at the time of analysis had DOR censored at their last disease assessment date.

PFS was defined as the interval from Day 1 to the earlier of a lymphoma progression or death from any cause; otherwise, PFS was censored at the last radiographic assessment date. If a participant had no post baseline radiographic assessment and a vital status of alive or unknown, PFS was censored at Day 1.

OS was defined as the time from the date of Day 1 until death due to any cause. Any participant not known to have died at the time of analysis was censored based on the last recorded date on which the participant was alive.

Amgen

Serious adverse events and other adverse events are reported for all participants who received at least one dose of study drug. Mortality reporting is reported for all participants enrolled.

Participants with relapsed/refractory diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL), or follicular lymphoma (FL) received AMG 562 0.1 μg administered as once weekly intravenous (IV) infusions for up to approximately 8 months.

Cohort 1: AMG 562 0.1 μg

Participants with relapsed/refractory DLBCL, MCL, or FL received AMG 562 0.3 μg administered as once weekly IV infusions for up to approximately 8 months.

Cohort 2: AMG 562 0.3 μg

Amgen decided not to continue development of AMG 562 because of a business decision and not because of safety reasons. No conclusions can be drawn due to the small sample size of this study.
