Janssen Highlights Impact of Multiple Sclerosis-Related Fatigue with Real- World Study Data Presentation at MSVirtual2020 and Global Patient Survey

Poster Presentation Shares New Data on the Symptoms and Impacts of Fatigue

Using a New Disease-Specific Scale

Global Patient Survey Reveals Approximately Two-Thirds of Multiple Sclerosis

Patients Experience Fatigue on a Daily Basis

Titusville, N.J., September 11, 2020 - The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new data from a real-world evidence study demonstrating high levels of fatigue and impacts on patients' lives in the areas of physical, cognitive/emotional and coping activities among a majority of adult patients with relapsing multiple sclerosis (RMS). The data are being shared online as an accepted poster presentation (#P1004) during MSVirtual2020: 8th Joint ACTRIMS-ECTRIMSMeeting.

The study, which enrolled 200 U.S. patients with RMS measured multiple sclerosis (MS)-related fatigue and its impact on daily life using the Fatigue Symptoms and Impacts Questionnaire - Relapsing Multiple Sclerosis (FSIQ-RMS), a novel disease- specific scale developed using methods consistent with the U.S. Food & Drug

Administration guidelines. The FSIQ-RMS is a patient-reported outcome instrument that has demonstrated content and measurement validity for RMS fatigue-related symptom and impact items. The MS symptom with most impact on daily functioning was fatigue (33 percent), followed by walking difficulties (25 percent).

"At Janssen, we approach diseases holistically, considering both fundamental and secondary - or 'hidden' - symptoms that may affect the well-being of people living with neurodegenerative conditions, like MS," said Bill Martin, Ph.D., Global Therapeutic Area Head, Neuroscience, Janssen Research & Development, LLC. "We developed the FSIQ-RMS to better understand and measure the severity of MS- related fatigue and its impact on daily functioning, so that these insights can be applied to develop meaningful therapeutic options, as well as educational initiatives, to help people with MS and their healthcare team better manage this prominent symptom."

Separately, Janssen, in partnership with the National Multiple Sclerosis Society (NMSS), recently conducted a global patient research survey to examine the impact of MS-relatedfatigueon social and emotional aspects of daily life. The survey included 1,300 adult patients with MS living in the U.S., Germany, Canada, France, the UK and Italy. Survey results show that more than 65 percent of patients with MS experience fatigue on a daily basis with 60 percent stating their fatigue has worsened since their diagnosis. Other survey findings include the following:

• More than 75 percent of patients agree it's difficult for others in their life to truly understand how fatigue impacts them.
• Nearly 70 percent of respondents feel that they should hide their fatigue from others.
• Over 40 percent of respondents reported feeling lonely as a result of their fatigue.

• Approximately 37 percent stated they had trouble making new friends or had strained friendships because of fatigue.
• Nearly half of patients take breaks throughout the day to manage their fatigue. In the workplace specifically, 85 percent reported their fatigue impacts how they feel and act at work.
• More than one-third of respondents reported that they either arrived late or left work early, called in sick (from work) or missed family/social activities because of their fatigue.
• More than 90 percent of patients have discussed their fatigue with their healthcare provider (HCP); however, 56 percent say they don't feel their HCP fully understands the overall impact fatigue has on their daily lives.

About Multiple Sclerosis (MS)

MS is a chronic autoimmune inflammatory disease of the central nervous system affecting 2.3 million people worldwide,i with females more impacted than males.ii The disease is characterized by demyelinationii and axonal loss leading to neurological impairment and severe disability.iii Relapsing forms of MS, which make up 85 percent of all MS cases, include clinically isolated syndrome, relapsing- remitting MS and active secondary progressive MS.iv In addition to the debilitating neurological symptoms of the disease, patients often also suffer from "hidden symptoms," namely fatigue and depression, both of which are major contributors to reduced quality of life.v Fatigue is one of the most common symptoms of MS, occurring in about 80 percent of patients.vi

Relapses are defined as new, worsening or recurrent neurological symptoms that last for more than 24 hours with the absence of fever or infections. Relapses may be fully resolved over days or weeks or lead to persistent residual deficits and accumulation of disability.vii
