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.

Eligibility criteria: Inclusion Criteria:

* Documented RRMM after last treatment. Refractory is defined as meeting 1 or more of the following: Nonresponsive to most recent therapy (stable disease \[SD\] or progressive disease \[PD\]) while on treatment, or Disease progression within 60 days of discontinuation from the most recent therapy.
* Eligible to receive Kyprolis per the locally approved label.
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
* Adequate hepatic function within 28 days prior to enrollment: bilirubin \< 1.5 times the upper limit of normal (ULN); aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 2.5 times the ULN.
* Absolute neutrophil count (ANC) ≥ 1.0 x 10\^9 /L within 28 days prior to enrollment. (Screening ANC should be independent of granulocyte- and granulocyte macrophage-colony stimulating factor support for at least 1 week and of pegylated granulocyte stimulating factor for ≥ 2 weeks).
* Hemoglobin ≥ 80 g/L within 28 days prior to enrollment. Subjects should not have received red blood cell (RBC) transfusions for at least 7 days prior to obtaining the screening hemoglobin.
* Platelet count ≥ 75 x 10\^9/L (≥ 50 x 10\^9/L if myeloma involvement in the bone marrow is ≥ 50%) within 28 days prior to enrollment. Subjects should not have received platelet transfusions for at least 7 days prior to obtaining the screening platelet count.
* Adequate renal function within 28 days prior to enrollment (either measured or calculated using a standard formula such as the Cockcroft and Gault): calculated or measured creatinine clearance (CrCl) of ≥ 50 mL/min for subjects receiving KRd; calculated or measured CrCl of ≥ 15 mL/min for subjects receiving Kd.
* Left ventricular ejection fraction ≥ 40% as assessed by transthoracic echocardiogram (TTE) or multigated acquisition scan (MUGA).
* Females of childbearing potential (FCBP) must have a negative serum pregnancy test within the 10 to 14 days prior to enrollment and a negative urine pregnancy test within the 24 hours prior to day 1 of each cycle prior to dosing.
* Subject or legally acceptable representative has provided informed consent/assent prior to initiation of any study specific activities/procedures.

Exclusion Criteria:

* POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)
* Myelodysplastic síndrome.
* Primary amyloidosis (subjects with multiple myeloma with asymptomatic deposition of amyloid plaques found on biopsy would be eligible if all other criteria are met).

Adequately treated cervical carcinoma in situ without evidence of disease. Adequately treated breast ductal carcinoma in situ without evidence of disease. Prostatic intraepithelial neoplasia without evidence of prostate cáncer. Adequately treated urothelial papillary noninvasive carcinoma or carcinoma in situ.
* Known immediate or delayed hypersensitivity reaction to Captisol (a cyclodextrin derivative used to solubilize Kyprolis).
* Contraindication to any of the required concomitant drugs or supportive treatments, including hypersensitivity to antiviral drugs.
* Intolerance to hydration.
* Active congestive heart failure (New York Heart Association \[NYHA\] Class III to IV), symptomatic ischemia, uncontrolled arrhythmias, clinically significant echocardiogram (ECHO) abnormalities, screening ECG with corrected QT interval (QTc) of \> 470 msec, pericardial disease, or myocardial infarction within 4 months prior to enrollment.
* Infiltrative pulmonary disease and/or known pulmonary hypertension.
* Active infection within 14 days prior to enrollment requiring systemic antibiotics, antiviral (except antiviral therapy directed at hepatitis B) or antifungal agents. Such infections must be fully resolved prior to initiating study treatment.
* Pleural effusions requiring thoracentesis within 14 days prior to enrollment.

Subjects with known history or resolved infection (negative for HBsAg but positive for antibodies to surface antigen, and/or core antigen) must be screened with HBV DNA levels. EXCEPTION: Subjects with serologic findings suggestive of HBV vaccination (hepatitis B surface antibody \[anti-HBs\] positivity as the only serologic marker) AND a known history of prior HBV vaccination, do not need to be tested for HBV DNA.
