Safety and activity of anti-CD14 antibody IC14 (atibuclimab) in ALS: Experience with expanded access protocol.

INTRODUCTION/AIMS: IC14 (atibuclimab) is a monoclonal anti-CD14 antibody. A previous phase 1 trial of 10 participants with amyotrophic lateral sclerosis (ALS) demonstrated initial safety of IC14 in an acute treatment setting. We provided long-term treatment with IC14 to individuals with ALS via an expanded access protocol (EAP) and documented target engagement, biomarker, safety, and disease endpoints. METHODS: Participants received intravenous IC14 every 2 weeks. Consistent with United States Food and Drug Administration guidelines, participants were not eligible for clinical trials and the EAP was inclusive of a broad population. Whole blood and serum were collected to determine monocyte CD14 receptor occupancy (RO), IC14 levels, and antidrug antibodies. Ex vivo T-regulatory functional assays were performed in a subset of participants. RESULTS: Seventeen participants received IC14 for up to 103 weeks (average, 30.1 weeks; range, 1 to 103 weeks). Treatment-emergent adverse events (TEAEs) were uncommon, mild, and self-limiting. There were 18 serious adverse events (SAEs), which were related to disease progression and unrelated or likely unrelated to IC14. Three participants died due to disease progression. Monocyte CD14 RO increased for all participants after IC14 infusion. One individual required more frequent dosing (every 10 days) to achieve over 80% RO. Antidrug antibodies were detected in only one participant and were transient, low titer, and non-neutralizing. DISCUSSION: Administration of IC14 in ALS was safe and well-tolerated in this intermediate-size EAP. Measuring RO guided dosing frequency. Additional placebo-controlled trials are required to determine the efficacy of IC14 in ALS.

Ultrasound-guided glenohumeral joint injections for shoulder pain in ALS: A case series.

Introduction: Shoulder pain is a common secondary impairment for people living with ALS (PALS). Decreased range of motion (ROM) from weakness can lead to shoulder pathology, which can result in debilitating pain. Shoulder pain may limit PALS from participating in activities of daily living and may have a negative impact on their quality of life. This case series explores the efficacy of glenohumeral joint injections for the management of shoulder pain due to adhesive capsulitis in PALS. Methods: People living with ALS and shoulder pain were referred to sports medicine-certified physiatrists for diagnostic evaluation and management. They completed the Revised ALS Functional Rating Scale and a questionnaire asking about their pain levels and how it impacts sleep, function, and quality of life at baseline pre-injection, 1-week post-injection, 1 month post-injection, and 3 months post-injection. Results: We present five cases of PALS who were diagnosed with adhesive capsulitis and underwent glenohumeral joint injections. Though only one PALS reported complete symptom resolution, all had at least partial symptomatic improvement during the observation period. No complications were observed. Conclusions: People living with ALS require a comprehensive plan to manage shoulder pain. Glenohumeral joint injections are safe and effective for adhesive capsulitis in PALS, but alone may not completely resolve shoulder pain. Additional therapies to improve ROM and reduce pain should be considered.

Patient reported outcomes in ALS: characteristics of the self-entry ALS Functional Rating Scale-revised and the Activities-specific Balance Confidence Scale.

Objective: This study characterized two patient-reported outcome measures (PROMs): a patient-facing adaptation of the revised amyotrophic lateral sclerosis (ALS) Functional Rating Scale ("self-entry ALSFRS-R") and the Activities-specific Balance Confidence (ABC) Scale. Methods: ALS patients presenting to clinic completed PROMs that included (1) the self-entry ALSFRS-R, (2) the Activities-specific Balance Confidence Scale (ABC Scale), and (3) a question about falls. PROM data were compared to one another and to the traditional ALSFRS-R collected by trained evaluators in clinic ("standard ALSFRS-R"). Results: Over the data collection period, 449 ALS patients completed at least one of the three PROMs. Self-entry vs. standard ALSFRS-R total scores (n = 183) had high agreement (intraclass correlation (ICC)=0.81, 95% CI = 0.67, 0.88). Self-entry ALSFRS-R total scores were significantly higher than standard ALSFRS-R total scores (2.3 points, p < 0.001). In a subset of participants who contributed data at two timepoints, the average ALSFRS-R decline was not significantly different between methods (n = 49). ABC scores correlated highly with self-entry and standard ALSFRS-R Gross Motor subdomain scores (Pearson's r = 0.72, p < 0.001 and Pearson's r = 0.76, p < 0.001, respectively; n = 130). ABC score was negatively correlated with the number of reported falls within the last month (Spearman's r=-0.40; p < 0.001; n = 130). A 10-point decrease in ABC score increased odds of a reported fall by 16%. Conclusions: In a multidisciplinary clinic setting, self-entry and standard ALSFRS-R scores were similar, but not interchangeable. Self-entry scores were higher than standard ALSFRS-R scores but declined at a similar rate to the standard ALSFRS-R. ABC scores correlated with self-reported fall history and thus may provide useful data for clinical care.

Exploring the use of educational materials for increasing participation in a stretching program: a quality improvement project in people with motor neuron disease.

BACKGROUND: Decreased range of motion is a common secondary complication of motor neuron disease (MND) that can contribute to functional decline and decreased participation in daily activities. AIM: The purpose of this study was to develop and assess the effectiveness of educational brochures and videos aimed at improving knowledge regarding the importance of a regular stretching program. DESIGN: This was a quality improvement (QI) project. SETTING: Participants were seen in an outpatient multidisciplinary neuromuscular clinic. POPULATION: Individuals with motor neuron disease were invited to participate in this QI study. METHODS: Individuals were asked to complete surveys asking questions regarding current stretching program, pain levels, and knowledge of benefits of stretching before and after receiving the stretching brochures or videos. RESULTS: A total of 53 participants completed the pre-intervention survey, 28 in the brochure group and 25 in the video group. Of those, 86% and 88% completed the post-intervention survey in the brochure and video groups, respectively. The video group increased stretching frequency significantly more than the brochure group (2.04 and 0.62 days/week respectively, P=0.004). Significantly more participants in the video group reported usage of stretches from the educational materials on a regular basis (54% for brochure group and 86% for video group, P=0.024). CONCLUSIONS: Educational brochures and videos are two different strategies to improve knowledge of benefits of stretching for individuals with MND. Both groups increased frequency of stretching. Videos may be better able to improve frequency of stretching when compared to brochures. CLINICAL REHABILITATION IMPACT: The brochures and videos developed for this study can be used by clinicians treating individuals with MND. By improving knowledge regarding the benefits of stretching, individuals with MND may choose to prioritize stretching as a part of their routine. This in turn may help to prevent or address potential joint or muscle length issues or assist patients to incorporate preventative measures into their treatment plans.

Patient reported outcome measures (PROMs) in amyotrophic lateral sclerosis.

OBJECTIVE: Patient reported outcome measures (PROMs) can provide researchers with a direct view of patients' experiences. They are becoming increasingly important tools for evaluating clinical care and research outcomes. There has been little data on the application of PROMs to amyotrophic lateral sclerosis (ALS) care. The objective of this study was to examine the feasibility of PROM collection in an academic ALS clinic and to measure correlations between PROMs and standard ALS clinical outcome measures. METHODS: PROMs were gathered from tablet-based surveys offered to adult patients in the waiting room, prior to ALS outpatient clinic visits. They included a demographic section and two validated surveys: the patient reported outcome measurement information system (PROMIS-10), which generates physical health and mental health subscores, and the quality of life in neurological disorders-fatigue subscale (NeuroQoL-fatigue). The ALS functional rating scale-revised (ALSFRS-R) and other ALS measures were collected by clinic staff as part of routine clinical care. RESULTS: PROMIS-10 physical and mental health scores correlated positively with the ALSFRS-R score (physical: R = 0.85, p < 0.001; mental: R = 0.58, p = 0.02). NeuroQoL-fatigue scores were inversely correlated with the ALSFRS-R scores-higher fatigue correlated with lower function (R = - 0.72, p = 0.004). CONCLUSION: Collection of PROMs is feasible in the context of routine ALS care. PROM scores are highly correlated with validated ALS outcome measures.

Adjusted cost analysis of video televisits for the care of people with amyotrophic lateral sclerosis.

INTRODUCTION: We previously reported our amyotrophic lateral sclerosis (ALS) video televisit experience. Here we report on video televisit versus in-clinic costs, adjusting for perceived medical usefulness (MU). METHODS: We take the patient-perspective and a focused institutional-perspective. Costs are adjusted for patient/caregiver and physician perceptions of visit MU. The base-case reflects our outpatient ALS practice. RESULTS: In the base-case, from the patient perspective, in-clinic visits cost $1,116 and video televisits cost $89 ($119 after MU-adjustment). From the institutional perspective, clinic visits cost $799, and video televisits cost $354 ($472 after MU-adjustment). Adjusted cost-savings per televisit are $997 (patient) and $327 (institution). Sensitivity analyses on 5 variables accounted for uncertainty in base-case assumptions. CONCLUSIONS: Video televisits provide marked adjusted cost-savings for patients and institutions. Adjusted costs are sensitive to perceived MU of video televisits. Future research should explore the ability of video televisits to reduce healthcare resource usage. Muscle Nerve 60: 147-154, 2019.

Exploring the Use of Educational Material About Shoulder Dysfunction: A Quality Improvement Project in People With Amyotrophic Lateral Sclerosis.

Shoulder pain is a common secondary complication of amyotrophic lateral sclerosis (ALS) that can contribute to functional decline and decreased participation in daily activities. The purpose of this study was to assess the effectiveness of an educational brochure aimed at improving knowledge regarding shoulder pain and dysfunction in people with ALS. Participants completed a preintervention survey with questions regarding their knowledge of how ALS may affect their shoulders. After completing the presurvey, they were mailed a brochure that described shoulder health and range of motion and stretching exercises. Four weeks after receiving the brochure, participants were then asked to determine the effectiveness of the educational materials in terms of impact on shoulder-related knowledge and self-efficacy with regard to prevention of shoulder pain and dysfunction. More than 50% of participants reported pain, decreased range of motion, or weakness in at least one shoulder since being diagnosed with ALS. All participants were interested in receiving educational materials, and all agreed that the brochure was easy to interpret and understand, with most (87%) reporting that it was helpful. Educational brochures are one strategy to improve awareness about shoulder health and to educate patients with ALS about exercises that may help reduce shoulder pain and dysfunction.

Experience with telemedicine in a multi-disciplinary ALS clinic.

OBJECTIVE: Telemedicine using video televisits is emerging as a means to provide care directly to patients. Here we report our experience using video televisits to provide follow-up care as a part of the Massachusetts General Hospital (MGH) Telemedicine for People with ALS (TelePALS) initiative. METHODS: This was a retrospective chart review of all video televisit encounters conducted by the MGH ALS clinic between September 2014 and January 2016. RESULTS: A total of 97 distinct ALS patients were seen using video televisits. Twenty-four percent of these patients had more than one video televisit. The median distance of the patients' primary residence to MGH was 211 miles. The average video televisit lasted 32 min (±12). About half the patients (54%) were ambulatory at the time of their video televisit. The most commonly addressed issues were medication management (89%), discussion of goals of care (74%), research (55%) and equipment use (50%). Acute care issues were rarely discussed. CONCLUSION: Video televisits are feasible and can be a useful tool to supplement traditional clinic-based multidisciplinary ALS care.

Preclinical Rodent Toxicity Studies for Long Term Use of Ceftriaxone.

A 6-month rodent toxicology and pharmacokinetic (PK) study was performed to provide supportive safety data for long-term use of intravenous ceftriaxone in a clinical trial in patients with amyotrophic lateral sclerosis (ALS). Ceftriaxone was administered by subcutaneous injection at up to 2 g/kg/day to Sprague-Dawley Crl:CD (SD) rats. Ceftriaxone was found to be safe and well tolerated. Specifically, no significant differences in body weight and food consumption were observed between the treatment and control groups. With the exception of in red cell parameters decrease, there were no ceftriaxone-related changes in hematology, coagulation, clinical chemistry and urinalysis parameters. Injection site trauma and associated reversible anemia, likely due to chronic blood loss at the injection site, were all attributable to subcutaneous route of administration. Cecum dilatation and some skin changes were reversible after recovery period, while bile duct dilatation, observed only in a few animals, persisted. Changes in the non-glandular stomach do not have a human correlate. The no-observed-adverse-effect dose level (NOAEL) was 0.5 g/kg/day ceftriaxone in both sexes. Ceftriaxone showed rapid absorption with half-life values ranging between 1 and 1.5 hours. Additionally, there was no evidence of accumulation and a virtually complete elimination by 16 hours after the last dose. Overall there were no toxicologically meaningful drug-related animal findings associated with the long-term administration (6 months) of ceftriaxone. These results support safety of long-term use of ceftriaxone in human clinical trials.
