MINI28.01 - The Impact of Physical Activity on Fatigue and Quality of Life in Lung Cancer Patients: A Randomized Controlled Trial (RCT) (ID 3173)
16:45 - 16:50 | Author(s): S. Clarke
- Abstract
- Presentation
Background:
Physical activity (PA) has been shown to improve fatigue and quality of life (QOL) in a range of cancer populations. Little research has been done in the advanced lung cancer setting. This RCT evaluated a 2-month PA intervention in patients with unresectable lung cancer.
Methods:
Participants were stratified (disease stage, performance status [PS] 0-1 vs 2, centre) and randomized (1:1) to usual care (UC) (general nutrition and PA education materials) or UC plus 2-month program of supervised weekly PA and behaviour change sessions and home-based PA. Assessments were completed at baseline, 2, 4 and 6 months. The primary endpoint was fatigue (FACT-F subscale) at 2-months. Secondary endpoints included: QOL, functional abilities, physical fitness, activity (accelerometers), mood, dyspnea, survival and blood results. Intention-to-treat analysis using linear mixed models was done.
Results:
111 patients were randomized: male 55%, median age 62 (35-80); 95% NSCLC, 5% SCLC; 95% Stage IV. At baseline 77% were on active treatment. Baseline characteristics, including PA levels, comorbidities and Glasgow Prognostic Score (GPS) were well balanced between groups. Attrition was 22, 36 and 50% at 2, 4 and 6 months respectively; no difference between groups. Adherence to intervention sessions: behavioral 77%, PA 69%. There were no significant differences in fatigue, QOL, symptoms, mood, distress, sleep, dyspnea, activities of daily living, GPS between the groups at 2, 4 or 6 months. Patients over report PA levels compared to accelerometer data. Using accelerometer data, PA only increased in the PA group from 0 – 2 months, but the difference in PA between groups was not significant. Median survival (months): PA 13.7 vs UC 12.6 (p= 0.76): 38 participants remain alive.PA n=55 UC n=56 p-value FACT-F Fatigue: 0 2 4 6 38.4 37.5 39.6 36.6 36.3 36.3 35.4 34.5 0.61 0.10 0.44 EORTC Global QOL 0 2 4 6 63.8 63.2 64.2 60.8 58.9 64.3 60.2 54.2 0.81 0.45 0.26 Performance Status 0 2 4 6 0.8 0.8 0.8 0.7 0.9 1.0 1.0 1.2 0.30 0.16 0.01
Conclusion:
Adherence to the 8-week intervention was good but did not increase PA levels compared to education materials alone. No difference was seen in fatigue, QOL, symptom control or functional status.

ORAL26.07 - Early Signs of Clinical Activity of a MicroRNA-Based Therapy in a Phase I Study in Recurrent Malignant Pleural Mesothelioma (ID 1101)
11:50 - 12:01 | Author(s): S. Clarke
- Abstract
- Presentation
Background:
Recently we demonstrated that members of the miR-15/16 family of microRNAs are implicated as tumor suppressors in malignant pleural mesothelioma (MPM) (Reid et al, Ann Oncol, 2013). MesomiR 1 is a first-in-man study testing TargomiRs (miR-15/16-derived mimics packaged in EDV[TM]nanocells [EDVs] targeted with EGFR antibodies) in MPM patients.
Methods:
In this phase I study (ClinicalTrials.gov: NCT02369198) a standard 3-6 patient dose escalation cohort design examining weekly/twice weekly administration of TargomiRs is followed. Patients tolerating weekly/twice weekly TargomiR infusions well are allowed to continue experimental therapy for at least 8 weeks. Fifty percent of the MTD previously established for EDVs was chosen as the first dose level to be studied and corresponded to 5 billion EDVs containing 1.5 μg miR-15/16 mimics. Based on prior experience with EDVs, patients who presented with elevated IL-6 levels were given a dose adaptation period of two weeks before receiving phase I doses. Premedication consisted of dexamethasone, promethazine and paracetamol and patients were monitored for a minimum period of 3 hours after TargomiR infusion. Response assessment (CT, FDG-PET, pulmonary function) was scheduled for patients completing 8 weeks of treatment. Quality-of-Life (QoL) questionnaires (EORTC) were requested on a weekly basis.
Results:
Ten MPM patients have enrolled to date. The majority of patients receiving 5 billion TargomiRs experienced a period of shivering/rigor 80-90 minutes after the start of the infusion, sometimes associated with burning/painful sensations in the area of disease. Overall TargomiR treatment was well tolerated and no patient failed to complete the first (8 weeks) treatment period. Laboratory examination revealed a steep but transitory rise in inflammatory cytokines, neutrophilia and lymphopenia shortly after TargomiR infusion, sometimes accompanied by mild elevation of liver enzymes. QoL assessment (9 patients) showed improving scores in 3 patients, stabilization in 4 and slightly lower scores in 2 patients. Response assessment (modified RECIST) in the 6 patients completing 8 weeks of treatment to date: 1 PR (see Figure 1, reconfirmed after 12 and 16 weeks), 4 SD and 1 PD. Figure 1.

Conclusion:
Early MesomiR 1 data revealed that infusions with 5 billion TargomiRs were well tolerated. Transient inflammatory (cytokine-mediated) reactions were noted shortly after TargomiR administration. One objective response was recorded while stable disease and stable QoL scores were noted in the majority of patients completing 8 weeks of experimental treatment.
