Non-chemotherapeutic Interventions

PRIMARY OBJECTIVES:

I. To assess the impact of different lifestyle and low side effect interventions (exercise, nutrition, stress effects reduction) on immune markers in patients with monoclonal plasma cell disorders.

SECONDARY OBJECTIVES:

I. To assess the impact of different lifestyle and low side effect interventions (exercise, nutrition) on bone turnover parameters, body composition, the microbiome and physical fitness in patients with monoclonal plasma cell disorders.

II. To assess the impact of different lifestyle and low side effect interventions (exercise, nutrition, stress effect reduction) on parameters of stress, mental health and quality of life in patients with monoclonal plasma cell disorders.

OUTLINE: Patients are assigned to Module A, B or C.

MODULE A: Patients undergo strength training sessions twice weekly supervised by a licensed and specialized personal trainer via the internet (e.g., remote access) for 6 months. Patients also wear a FitBit device and receive prompts via email or text on a cell phone or other electronic device to incrementally increase physical activity over 6 months.

MODULE B: Patients undergo intermittent fasting for 1 month. This consists of restricting all eating to a consecutive 8-hour time period each day followed by 16 consecutive hours of not eating.

MODULE C: Patients are assigned to group 1 (are not currently taking beta-blockers) or group 2 (current taking beta-blockers).

GROUP I: Patients receive propranolol orally (PO) twice daily (BID) for 3 months.

GROUP II: Patients continue receiving beta-blocker regimen as per standard of care (SOC) for 3 months.

After completion of the study interventions, patients in module A are followed every 3 months for 1 year. Patients in module B are followed at 3 and 5 months. Patients in module C are followed for 3 months.
