Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Confirmation that the subject is not pregnant must be established by a negative serum beta-human chorionic gonadotropin (B-hCG) pregnancy test result obtained during screening. Pregnancy testing is not required for post-menopausal or surgically sterilized women. * Documented hypersensitivity to fludarabine or melphalan or to bortezomib, boron or mannitol or any components of the formulation * Patients unable or unwilling to provide consent * Patient has a sustained platelet count of \<30 x 10 9/L within 14 days before enrollment * Patient has a sustained absolute neutrophil count of \<1.0 x10 9/L within 14 days before enrollment * Myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at screening has to be documented by the investigator as not medically relevant * Patient has received other investigational drugs with 14 days before enrollment * Serious medical or psychiatric illness likely to interfere with participation in this clinical study
