ABSTRACT: Purpose: Fatigue is a common problem among multiple myeloma (MM) patients. Armodafinil is a drug known to promote wakefulness, which is related to modafinil, a compound that improves fatigue in some cancer patients treated with chemotherapeutic agents. We investigated whether armodafinil could reduce cancer-related fatigue in MM patients. Methods: This double-blind, placebo-controlled phase 3 trial evaluated the efficacy of armodafinil in MM patients with evidence of moderate fatigue. Patients were randomized to one of two arms: treatment-only, with armodafinil given at 150 mg/daily for 56 days, or placebo-first, with placebo given on days 1-28, followed by armodafinil administered at 150 mg daily on days 29-56. Fatigue was measured on days 1 (pre-dose: baseline), 15, 28, 43, and 56 using seven separate assessments, including four patient-reported outcomes of fatigue and related quality of life measures, as well as three objective measures of cognitive function. Results: Overall toxicities were similar between treatment groups. No significant differences were observed between the placebo-first and the treatment-only arms after 28 days. Treatment with armodafinil for 28 additional days did not produce responses. Both placebo-first and treatment-only patients showed similar significant improvements in three patient-reported measures and one objective task at day 28 compared to baseline. Placebo-first patients improved on eight additional measures (one patient-reported measure, six subscales, and one objective task), suggesting a strong placebo effect in this patient population. Conclusions: Evaluation and treatment of cancer-related fatigue continues to be challenging; a clear definition of this symptom and better assessment tools are needed.

ABSTRACT: Few studies have evaluated prognostic factors among patients with multiple myeloma (MM) since new therapies have become available. Monthly zoledronic acid (ZOL) has been incorporated into many treatment regimens to reduce skeletal-related events (SREs), but outcomes among patients receiving this bisphosphonate have not been well-defined. The aim of this retrospective study was to determine baseline and on-treatment prognostic factors in these patients. Data were collected from the date of diagnosis on 300 consecutive MM patients treated with ZOL. Median duration of ZOL was 18 months (range 1-121 months). The skeletal morbidity rate was 0.116 events per patient year. Five-year overall survival (OS) was 69%. Risk factors for shortened OS included SREs, increased serum creatinine, and International Staging System (ISS) Stage II or III. Thirty-four (11%) patients showed worsening renal function. In 28 of these patients, ZOL was discontinued and restarted in half of these patients following a brief delay. Only 5 of the 34 patients showed worsening of their renal function. Fourteen patients (4.7%) developed osteonecrosis of the jaw (ONJ). All patients with ONJ are in remission or with stable disease except one patient who died of a myocardial infarction while in remission. Only two patients showed some worsening of ONJ despite of ongoing monthly ZOL. Overall, these results suggest that skeletal complications are an important prognostic factor for MM. Although ONJ and renal deterioration may infrequently occur with ZOL, most patients do not experience worsening of these conditions with ongoing treatment with this bisphosphonate.
