Background Japanese (both in Japan and Hawaii) have a lower incidence of falls and of hip fracture than North American and European Caucasians, but the reasons for these differences are not clear. Subjects and Methods A cross-sectional study. We compared neuromuscular risk factors for falls using performance-based measures (chair stand time, usual and rapid walking speed, and grip strength) among 163 Japanese women in Japan, 681 Japanese-American women in Hawaii and 9403 Caucasian women in the United States aged 65 years and over. Results After adjusting for age, the Caucasian women required about 40% more time to complete 5 chair stands than either group of Japanese. Walking speed was about 10% slower among Caucasians than native Japanese, whereas Japanese-American women in Hawaii walked about 11% faster than native Japanese. Grip strength was greatest in Japan, which may reflect the rural farming district that this sample was drawn from. Additional adjustment for height, weight or body mass index increased the adjusted means of chair stand time and grip strength among Japanese, but the differences remained significant. Conclusions Both native Japanese and Japanese-American women in Hawaii performed better than Caucasians on chair stand time and walking speed tests, and native Japanese had greater grip strength than Japanese in Hawaii and Caucasians. The biological implications of these differences in performance are uncertain, but may be useful in planning future comparisons between populations.

Rationale for the Study: Phase 1 pharmacokinetic (PK) data is needed in Chinese and Japanese populations to support future clinical development of BIIB023 in China and Japan.

Study Design: This is a single-dose study to assess the PK, safety, and tolerability of BIIB023 administered intravenously (IV) to adult Chinese, Japanese, and Caucasian healthy volunteers. The Caucasian group is included to allow comparison of PK data from different groups using data from the same study under the same controlled conditions.

Subjects will be in the clinic for 48 hours around the time of dosing and in the study for up to 100 days.
