Study of Induction Treatment With Velcade and Dexamethasone for Previously Untreated Patients With Multiple Myeloma and Renal Failure
Study of Induction Treatment With Velcade and Dexamethasone for Previously Untreated Patients With Multiple Myeloma and Renal Failure
Primary outcome measure:

 -  Analyze the efficacy (in order to evaluate the response) of Bortezomib/Dexamethasone
 treatment

 Secondary outcome measures:

 -  Study the speed of response and the response rate (M component in serum and urine
 protein) after each bortezomib/dexamethasone cycle

 -  Compare the efficacy of the bortezomib/dexamethasone therapy against the therapy without
 bortezomib

 -  Reversibility of renal failure

 -  Predictive value in the light chain determination for response and reversibility of
 renal failure

 -  Early morbidity (< 2 months)

 -  Progression-free survival

 -  Overall survival

 The safety outcome consists in:

 -  Determining the safety and tolerance of VELCADE/Dexamethasone, according to the toxicity
 criteria of clinical and laboratory events
60 patients, 18 years or older, diagnosed with newly symptomatic multiple myeloma (standard
 diagnosis criteria) and renal failure, previously untreated with chemotherapy, will be
 included.

 It is an multi centric, national and open study designed in order to determine efficacy of
 the combination of bortezomib and dexamethasone for multiple myeloma patients with renal
 failure.

 The trial consists of two parts: pre-treatment and treatment. Pre- treatment phase: include
 the enrolment visit in order to determine that the patient is eligible to participate in a
 study. The patient will be given the Informed Consent Form in order to participate in the
 study, and detailed information about the treatment, its benefits and risks.

 Treatment phase: include the treatment which consist of, at the most, 12 cycles of Velcade
 and Dexamethasone (induction and extension). During these periods, patients will come to the
 centre for the study visits to be evaluated, the days they will receive Velcade® of each
 cycle.

 Once the clinical trial has finished, patients will be monitored during short and long-term
 periods where progression free survival and overall survival will be evaluated.
Inclusion Criteria:

 -  The patient must, according with investigator criteria, be able to comply with all the
 protocol requirements

 -  The patient or legal representative must sign voluntarily the informed consent before
 the performance of any study related procedure, not part of usual medical care, with
 the knowledge that can leave the study the moment he/she wants, without prejudice to
 later medical care

 -  18 years and older

 -  Patients with newly diagnosed symptomatic multiple myeloma43 which hasn't been treated
 previously with any chemotherapy used for this disease (see Annex 8)

 -  Patient with a measurable or evaluable disease, defined as follows:

 -  For secretor multiple myeloma, measurable disease is defined as any quantifiable
 serum monoclonal protein value of IgG>10g/l or IgA > 5 g/l and, where applicable,
 urine light-chain excretion of ≥ 200 mg/24 hours

 -  For oligo or non-secretor multiple myeloma, measurable disease is defined by the
 presence of soft tissue plasmocytomas (not bone) determined by clinical
 examination or applicable radiographs (i.e. MRI, CT-Scan). In patients with low
 secretor multiple myeloma, the serum and/or urine M-protein measurements are very
 low and difficult to follow for response assessment. In patients with
 non-secretor multiple myeloma, there is no M-protein in serum or urine by
 immunofixation

 -  ECOG performance status ≤ 2 (see Appendix 5)

 -  Patient has a life-expectancy >3 months

 -  Glomerular filtration calculated with MDRD <50 ml/min

 -  Patient has the following laboratory values during the 14 days before first dose:

 -  Platelet count ≥ 50x109/l

 -  Absolute neutrophil count (ANC) ≥ 0.75 x 10 9/ L

 -  Corrected serum calcium (see Appendix 15) ≤ 14mg/dl

 -  Aspartate transaminase (AST): ≤ 2,5 x upper limit of normal

 -  Alanine Aminotransferase (ALT): ≤ 2,5 x upper limit of normal

 -  Total bilirubin: ≤ 1,5 x upper limit of normal

 Exclusion Criteria:

 -  Glomerular filtration calculated with MDRD ≥ 50ml/min

 -  Asymptomatic MM with renal failure from unrelated causes

 -  Prior Velcade therapy

 -  Patients previously received treatment to Multiple Myeloma

 -  Patient had major surgery within 4 weeks previous inclusion

 -  Patient with platelet count ≤ 50 x 109/l within 14 days before enrolment

 -  Patient with absolute neutrophil count ≤ 0,75x109/l within 14 days before enrolment

 -  Patients with Grade 2 peripheral neuropathy within 14 days before enrolment

 -  Patient has hypersensitivity to bortezomib, boron or mannitol

 -  Patient has received other investigational drugs within 14 days before enrolment

 -  Patient is known to be seropositive for the human immunodeficiency virus (HIV)

 -  Patient had a myocardial infarction within 6 months before of enrolment or has Class
 III or IV heart failure (New York Heart Association <NYHA>), uncontrolled angina,
 severe uncontrolled ventricular arrhythmias, or electrocardiography evidence of acute
 ischemia or active conduction system abnormalities, or other heart condition which,
 according with the specialist, can result in heart failure

 -  Patient is enrolled in another clinical research study and/or is receiving an
 investigational agent for any reason

 -  Patients with diffuse pulmonary disease and/or pericardial disease

 -  Pregnancy or breast-feed women and women of childbearing age that don't accept to use
 anticonceptive methods since beginning during all the study until 30 days after last
 cycle treatment. Fertile male patients must use effective form of contraception since
 enrolment, during and until 30 days after last cycle study treatment

 -  Patient with a previous clinical history of another malign illness except for squamous
 cell carcinoma or skin cancer or cervical or breast cancer) except the patient could
 be free of symptoms during ≥ 5 years

 -  Uncontrolled arterial hypertension or diabetes mellitus or other serious medical
 condition which places the subject at unacceptable risk or other psychiatric illness
 that would prevent the subject from understanding the informed consent form
