The goal of this clinical trial is to learn about the effects of inflammation-lowering therapy on mobility and disability in older adults. The main questions it aims to answer are:
Participants will be asked to receive injections of drug or placebo every 4 weeks for 24 weeks. They will also be asked to undergo testing that assesses physical function, thinking ability and brain health, breathing capacity, and blood vessel stiffness, and will have blood samples collected to measure immune function and to create a bank of samples for future testing. Comparisons will be made between those who receive drug and those who receive placebo.
The primary objective of this trial is to assess the impact of inflammation-lowering therapy with clazakizumab 5 mg/month on speed when walking 400 meters in older adults. The investigators hypothesize that participants treated with clazakizumab will see a larger 6-month improvement in their pace on a 400-meter walk than those provided placebo.
The aims of the study will be to:
This study will randomize 60 community living men and women 70 years of age and older who have mildly elevated IL-6 at baseline (≥ 2.0 pg/ml and < 30.0 pg/ml). Interested individuals will undergo telephone and in-person screening visits (two) to determine eligibility (blood will be collected to measure IL-6, height and weight will be measured, a 4m walk test will be administered to determine gait speed, and a review of medical history, medications, a physical exam, and blood safety labs will be conducted to ensure safety to proceed/eligibility). Randomization to study drug or placebo will take place within 60 days of the first in-person screening visit and subsequent injections will take place every 4 weeks for 24 weeks. Participants will undergo physical function testing (400m walk, preferred & fixed speed walk on a treadmill with oxygen consumption measurement, short physical performance battery, grip strength, actigraphy), cognitive testing, and aortic pulse wave velocity and endothelial function testing. Height, weight and pulse will be measured. Participants will complete questionnaires to assess demographics, physical activity level, fatigability, sleep quality, pain and depression. Blood will be collected/processed to measure immune function and stored frozen to create a biorepository of samples (serum, plasma, buffy coat) for future testing. Participants will be monitored for safety in between injection visits and for 5 months following the final in-person research visit.
