Interesting report. But all 4 donors had overt proteinuria at the time of organ allocation. Is it standard procedure to ignore that in deceased kidney donation? Tapping a transplantologist @georginairish.bsky.social @nymurakami.bsky.social #NephSky

Heir to the Throne? Obinutuzumab in the membranous nephropathy MAJESTY trial — NephJC
This week, NephJC will discuss whether obinutuzumab is ready to outperform tacrolimus in primary membranous nephropathy
nephjc.com
Agree - it would likely be a N of 1000 + trial, and one would need funding of Ritux for control + Obi for intervention. Also, note when Tac was stopped per @brycebarr.bsky.social above! www.kireports.org/article/S246... from Ruggenenti et al in @kireports.bsky.social with same thoughts #ERA26

I did not get at all why this was tested when ritux is alteady effective. So why not test obi against ritux? I asked the investigator and he said it would not be feasible, and they made this to get fda approval which there apparently isn’t for ritux.

This post was prompted by the fact that I was recently approached by a drug sponsor conducting a randomized clinical trial with a new drug vs tacrolimus. I cannot in good faith offer that to a patient. No medical equipoise.
When are clinical trials for membranous nephropathy going to stop using cyclosporin/tacrolimus as control group? We already know that CNIs are inferior to CYC, RTX & OBZ. It was already a criticizable choice in MENTOR. I cannot ethically offer that to a patient. Drug companies and FDA: please act

“Mrs/Mr XYZ, we are going to request to have the plastic catheter in your neck removed since you are not going to require more dialysis 🙂”. Immediate reaction of happiness elicited, from the patient and/or family. One of the most fulfilling moments during Nephrology rounds.
1/5 There has been a major shift in how we treat IgA nephropathy. New studies have shown that kidney failure risk begins at lower levels of proteinuria than previously appreciated, and multiple trials have demonstrated that targeted therapies can reduce the risk of progression.
Why does your IgA nephropathy care depend on who you see? In a Manitoba study published in #ASNKidney360, doctors drove 31% of variability in biopsy timing and 7% in steroid use. kidney.pub/KID1232 Bryce Barr

An interim analysis of a phase 3 trial involving patients with IgA nephropathy showed that 39 weeks of treatment with telitacicept led to a greater reduction in the 24-hour urinary protein-to-creatinine ratio than placebo. Full TELIGAN trial results and Research Summary: https://nej.md/4uFpMLz
