Efficacy of QBKPN Site-Specific Immunomodulator in Improving Innate Immune Function & Reducing Respiratory Tract Infection in Older Adults

This study is designed to test whether QBKPN SSI can improve immune function in older adults, including how well it can protect against respiratory and other infections, whether it improves the body's response to COVID-19 vaccines, what effect it has on maintaining or improving quality of life, activity level and health status and whether it has an effect on glycemic control.

QBKPN is a new medication in a class known as Site-Specific Immunomodulators (SSI). SSIs are designed to train and/or improve innate immune function to reduce the risk of infections, improve immune response to cancer, and slow the progression of chronic inflammatory diseases.

It is believed that QBKPN SSI can work with the immune system to help protect against respiratory and other infections.

About this study

This is a randomized, double-blind, placebo-controlled study of adults 65 years of age or older residing in the community, in independent-living, assisted-living and long-term care (LTC) facilities to assess the effect of QBKPN SSI on improvement of innate immunity and reduction of all-cause respiratory tract infection morbidity.

Approximately 72 participants will be enrolled; approximately 36 from the community and independent-living facilities and approximately 36 from assisted-living and LTC facilities.

Eligible participants will be screened and enrolled by study staff, who will conduct all study visits, and administer or teach self-administration of study treatment. Blood/sample collections will be performed by study staff or by staff at Vancouver Coastal Health Research Institute Clinical Research Unit. Participants will have the options of nurse-administration, self-administration or a combination of nurse- and self-administration of study treatment. Participants will receive study treatment for 4 weeks then be monitored for 22 weeks. Blood/urine sampling will be performed at Baseline, Weeks 4, End of Treatment, Week 8, Week 12 and Week 26. A phone call visit will be conducted at Week 20.

Immunological testing for trained innate immunity, capacity for anti-viral innate immune response, measures of immune augmentation, duration of adaptive immune response to SARS-CoV-2 vaccination and/or infection, change in metabolome and Natural Killer (NK) cell function will be performed.

Safety and tolerability of study treatment will be assessed through clinical laboratory parameters and treatment-emergent adverse events.

Clinical benefits of study treatment will be assessed via medical record review and patient-reported outcomes. Study staff will record any confirmed/probable/possible infections (viral and bacterial, including respiratory and non-respiratory), any microbiologic or radiologic testing performed to investigate for infection, any prescribed antibiotics/antivirals and duration of treatment and reason for and duration of any hospitalizations.

Clinical assessments will also include frailty index (Rockwood Clinical Frailty Scale), quality of life [Dementia Quality of Life Questionnaire(DEMQOL)], end-of-life prediction score (CHESS Scale) and all-cause mortality.
