A TEAE was any untoward medical occurrence in a clinical trial participant after the first dose of investigational product (IP) irrespective of a causal relationship with the IP. TEAEs were graded using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v.4.03. Any clinically significant laboratory changes over time were recorded as TEAEs.
measure
Number of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs)
time Frame
From the first dose date of any IP until the end of trial; median (min, max) time on trial was 8.7 (0.1, 37.2) months
description
A serious TEAE was any untoward medical occurrence in a clinical trial participant after first dose of IP irrespective of a causal relationship with the IP(s), that resulted in death, was immediately life threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, or another medically important serious event.

secondary Outcomes

description
PFS was defined as the time from first dose of IP until the earliest date of disease progression (PD) or death due to any cause. PD was per IMWG-URC, with progression assessments at intervals as per local standard of care. PD: increase of 25% from lowest response value in serum M-component and/or urine M-component and/or only in participants without measurable serum and urine M protein levels: the difference between involved and uninvolved free light chain (FLC) levels and/or only in participants without measurable serum and urine M-protein levels and without measurable disease by FLC levels, bone marrow (BM) plasma cell percentage; definite development of new bone lesions or soft tissue plasmacytomas; development of hypercalcemia. Medians were estimated using the Kaplan-Meier method. Corresponding 95% confidence intervals (CIs) were estimated using the method by Klein and Moeschberger (1997) with log-log transformation.

ORR was defined as the percentage of participants for whom the best overall response was a stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR) as determined by the IMWG-URC. CR: negative immunofixation on serum and urine, soft tissue plasmacytomas disappearance, \< 5% plasma cells in bone marrow (BM). sCR: CR and normal serum free light chain ratio and no clonal cells in BM by immunohistochemistry.

Full study description

brief Summary: To characterize safety associated with the use of Kyprolis under the locally approved label.
detailed Description: Kyprolis® (K; carfilzomib) was approved in India on 17 January 2017 as a prescription medication in combination with dexamethasone (Kd) or with lenalidomide (Revlimid®) plus dexamethasone (KRd) for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) following 1 to 3 prior lines of therapy. This non-comparative, interventional phase 4 study is designed to fulfil the post-marketing requirement to assess safety, tolerability, and efficacy of Kyprolis on Indian subjects with RRMM as per the locally approved label.
