PRIMARY OBJECTIVES: I. To evaluate the response rate to PS-341 (bortezomib) induction in patients with high risk, newly diagnosed multiple myeloma. SECONDARY OBJECTIVES: 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. TERTIARY OBJECTIVES: I. To explore a possible differential response to PS-341 with previously described adverse prognostic indicators. 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. OUTLINE: 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 unacceptable toxicity. 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.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
44 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation
: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.

Non-randomized allocation
: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment
: Participants are split into separate groups, each receiving a different treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Factorial assignment
: Participants receive different combinations of treatments.

Sequential assignment
: Participants receive treatments one after another in a specific order, possibly based on individual responses.

Other assignment
: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Quadruple-blind
: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Study Objectives
Primary Objectives

Eastern Cooperative Oncology Group (ECOG) Myeloma Response Criteria that follows the standard European Group for Blood and Bone Marrow Transplant criteria was used to evaluate patient response and progression. Patients who have complete disappearance of an M-protein and no evidence of myeloma in the bone marrow are considered to have complete response. 42 eligible and treated patients were included in the analysis.
Secondary Objectives

ECOG Myeloma Response Criteria that follows the standard European Group for Blood and Bone Marrow Transplant criteria was used to evaluate patient response and progression. Patients who have complete disappearance of an M-protein and no evidence of myeloma in the bone marrow are considered to have complete response. 15 eligible and treated patients were included in the analysis.

ECOG Myeloma Response Criteria that follows the standard European Group for Blood and Bone Marrow Transplant criteria was used to evaluate patient response and progression. Patients who have complete disappearance of an M-protein and no evidence of myeloma in the bone marrow are considered to have complete response. 7 eligible and treated patients were included in the analysis.

Progression-free survival is defined as time from randomization to disease progression or death from any cause, whichever occurred first. Disease progression is defined using the ECOG Myeloma Response Criteria. Kaplan-Meier method is used to estimate the 1-year progression-free survival probability. 42 eligible and treated patients were included in the analysis.
