The pandemic continues to be hard for many transplant recipients and their families and caregivers. COVID-19 vaccines are less effective for transplant recipients. This is due to their suppressed immune systems. As a result, transplant recipients who get COVID-19 are at a higher risk of hospitalization and death. Preventing severe disease in transplant recipients requires different strategies. A New Study The CDTRP’s COVID-19 research is centered on addressing patient, family, and caregiver priorities. We have engaged the transplant community to learn how research and policy can support the recovery of quality of life during COVID-19 and in future health concerns A new study examines how COVID-19 continues to affect child and adult transplant recipients and their families and caregivers living in Canada. CDTRP will work with 11 transplant centres in Canada. The aim is to create a flexible national plan to inform better policies and improve patient health. The study is called Addressing Critical Issues and Therapeutics Emerging in Transplantation in COVID-19 for Transplant Recipients (TREAT-COVID). This study will: Assess the safety and effectiveness of COVID-19 treatment options. Look at the physical and mental health of organ and stem cell transplant recipients. Analyze financial struggles of the transplant community associated with the pandemic Patients and their families can help by joining research studies. The information gathered from the TREAT-COVID study will be used to improve treatment plans, guide important decisions, and help everyone better understand COVID-19 and its impact on their lives

This randomized, controlled trial evaluates the efficacy and safety of iptacopan, an oral factor B inhibitor, for inducing and maintaining remission in patients with newly diagnosed or relapsed active GPA or MPA. Participants receive iptacopan or placebo in combination with a rituximab induction regimen. The study assesses primary outcomes related to clinical remission and secondary endpoints including disease relapse rates, GC-related toxicity, and changes in eGFR and UPCR. The target population includes patients with active ANCA-associated vasculitis requiring induction therapy.

This Phase III, randomized, multicentre, double-blind study evaluates the efficacy, safety, and tolerability of a zibotentan/dapagliflozin combination compared to dapagliflozin monotherapy. The study population includes patients with CKD and high proteinuria, specifically targeting those who remain at risk despite standard care. The primary objective is to determine if the addition of zibotentan, a selective endothelin A receptor antagonist, to the SGLT2 inhibitor dapagliflozin further reduces albuminuria. Researchers monitor changes in UACR and eGFR as key indicators of renal function and treatment response.

This Phase II-III multi-center randomized controlled trial evaluates whether urinary CXCL10 monitoring to detect and treat early subclinical rejection improves outcomes in adult renal transplant recipients. Patients with confirmed elevations in urinary CXCL10 between 2 weeks and 9 months post-transplant are randomized 1:1 to either an intervention arm or a standard-of-care control arm. The intervention group undergoes a renal biopsy for elevated CXCL10 levels, with biopsy-proven rejection treated per protocol, while the control group receives routine surveillance based on serum creatinine and proteinuria. All randomized participants undergo a protocol biopsy at 12 months to assess primary and long-term allograft outcomes.
