This phase II trial studies how well bortezomib works in treating patients with newly
diagnosed multiple myeloma. Bortezomib may stop the growth of cancer cells by blocking some
of the enzymes needed for cell growth.
I. To evaluate the response rate to PS-341 (bortezomib) induction in patients with high
risk, newly diagnosed multiple myeloma.
I. To evaluate progression free survival. II. To explore the response rate of patients who
relapse or progress on maintenance and then return to induction schedule.
III. To explore duration of second response.
I. To explore a possible differential response to PS-341 with previously described adverse
II. To explore specific gene expression profiles (GEP) that may predict response to therapy
to an agent or combination of agents used in the treatment of newly diagnosed myeloma.
III. To explore specific post-treatment gene expression profiles (GEP) in the patients who
have received 4 cycles of therapy and achieved a minimal response or better.
IV. To develop relevant information about the immune system for multiple myeloma patients
treated with PS-341.
INDUCTION TREATMENT: Patients receive bortezomib intravenously (IV) on days 1, 4, 8, and 11.
Treatment repeats every 3 weeks for up to 8 courses in the absence of disease progression or
MAINTENANCE TREATMENT: Patients who complete induction treatment without progressive disease
receive bortezomib IV on days 1 and 15. Courses repeat every 28 days in the absence of
disease progression or unacceptable toxicity.
REINDUCTION TREATMENT: Patients who progress while on maintenance treatment receive
bortezomib IV on days 1, 4, 8, and 11. Courses repeat every 3 weeks in the absence of
disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and
then every 6 months for 4 years.

while on study; the exception for corticosteroids is made for those taking chronic
corticosteroids for disorders other than myeloma, such as rheumatoid arthritis,
adrenal insufficiency, etc.
