We report a 41-year-old Caucasian female patient with a 12-year history of SLE complicated by debilitating nocturnal fevers and WHO Class IV lupus nephritis who for years was refractory to standard therapies but improved dramatically with canakinumab, an interleukin-1β (IL-1β)antagonist.

In contrast, the introduction of canakinumab provided a rapid reduction in nocturnal fevers within 6 weeks (i.e. decreased in frequency by 90%). Her proteinuria has also dropped from 3.5 g/24 h to 0.274 g/24 h, and her prednisone has been tapered and discontinued. In addition, her renal function has improved with an average glomerular filtration rate (GFR) level of 84.14 ± 7.56. There has also been a significant decrease in both erythrocyte sedimentation rate (ESR) and anti-dsDNA levels compared with the previous treatments. We report that canakinumab could potentially represent the next step in SLE patients' treatment who have failed conventional therapies or who are intolerant to them.

The conference was held over 4 days from 10:00 a.m. to 12:30 p.m. Eastern Time on each day, which accommodated participation by speakers and attendees from both the eastern and western hemispheres. The agenda over 4 days holistically covered broad topics of interest to different stakeholder groups such as representatives from organizations working toward policy frameworks for rare diseases or orphan drugs (Days 1, 4), biomedical research institutions (Day 2), patient advocacy organizations (Day 3), and patient advocacy and engagement offices within Industry (Day 4). In this meeting report, we summarize the key highlights from each day of this conference, with a perspective on future directions encouraging cross-border multistakeholder collaborations to maximize diversity, equity, and inclusion (DEI) in rare disease diagnosis, research, clinical trials, and treatment access. Each day included a keynote lecture on the theme of the day followed by a series of individual speaker presentations and/or a panel discussion. The goal was to understand current barriers and bottlenecks in the rare disease ecosystem. The discussions also helped highlight gaps and identify potential solutions that can be achieved through building multistakeholder collaborations across international borders, which we believe IndoUSrare is uniquely positioned to do with organizational programs such as rare patient foundation alliance, technology-enabled patient concierge, research corps, and corporate alliance program. The inaugural conference of the then 2+-year-old IndoUSrare organization laid the foundation for ongoing engagement of stakeholders between the two countries - the United States and India.
