Really excited to have our story on a CYP17A1-independent androgen biosynthesis pathway out today! We think this could be a reason for why androgens are left with abiraterone tx in prostate cancer. @dsui_miami_uro @SylvesterCancer @PCFnews @ASCO @AACR

(4/4) OS analysis is immature, inconclusive with median fu of 20 months. Plan to update in ~ 1 year. Thank you to the patients, families, and providers who participated in this study.

(3/4) Len + eve had numerically higher SAEs, G3/4 AEs, and tx d/c than cabo, none significantly different between groups. 5/8 stopped len + eve for proteinuria

(2/4) Lenvatinib + everolimus significantly reduced the hazard for PD by 49% compared to cabozantinib. Len + eve also produced an ORR of 53% compared to 39% with cabo, not statistically significant.

(1/4) Here’s a tweetorial for LenCabo now available in @Annals_Oncology, https://t.co/qDJrPsv9yD This was a multicenter, phase 2 trial that randomized 90 patients with mccRCC and is the 1st head-to-head comparison of contemporary angiogenesis TT after PD-1 CPI

2/5 Clinically, 10 pts with RMC were treated; there were no confirmed responses, median PFS was ~1.4 months, and 5/10 met radiologic criteria for hyperprogression. Thus, for RMC immune checkpoint combination was not just ineffective; it could be harmful.

1/5 Our new @NatureComms study reports the first-ever dedicated clinical trial for #RenalMedullaryCarcinoma (RMC): phase II trial of #nivolumab + #ipilimumab and what it taught us about hyperprogression to immunotherapy: https://t.co/q1UwZr8L3i

This is great news for our patients, HLD-0915 and the AR RIPTAC tech will continue development with a strong team @BGarmezy @AarmstrongDuke @charlesryanmd @DCockrellMD
Big Pharma movement following promising early phase 1/2 data from a trial led by our own @OncHahn @MDAndersonNews in men with progressing mCRPC. @PCFnews J&J buys into Halda's cell death tech with $3B acquisition, beefing up prostate cancer pipeline

Incredible representation for chRCC at #IKCSNA25 including a phenomenal oral abstract presented by Sahil D. Doshi, MD summarizing the largest multi-institutional analysis to date on outcomes of metastatic chromophobe RCC with and without sarcomatoid features!

This is the most effective therapy we have developed to date for #RenalMedullaryCarcinoma contributing greatly to the recent doubling of median survival for this disease. Still much work to be done to #EndRMC and all rare &common #kidneycancer subtypes but the momentum is strong!
⭐ #IKCSNA25 HIGHLIGHT Panitumumab+nab-paclitaxel is reshaping care for heavily pretreated #RenalMedullaryCarcinoma. ORR 53.9% (CR 15.4%). @PavlosMsaouel @MDAndersonNews bringing hope & accelerating research for #RareKidneyCancers. #MsaouelLab #endRMC

Great session at @KidneyCancer meeting on subsequent line therapy moderated by @AlbigesL and @WesleyYipMD with @MdArpita Lisa Henske, Martin Voss, and Anand Swamimath. Specially great discussion about radiation for oligoprogression! But I may be biased 😜

In a couple of minutes at #IKCSNA25, excited to talk about building a clinical trials program. Not sure that I have it right, but these are a couple of slides reflecting my personal thoughts below - hoping it will stimulate some good discussion! Thanks to @ZakhariaYousef

Strong data in metastatic ccRCC after prior PD-1 therapy 📊 • Lenvatinib + Everolimus vs Cabozantinib • PFS 15.7 vs 10.2 months (HR 0.51, p=0.02) • ORR 52.6% vs 38.6% • 1-year OS ~87% vs ~84.6% (immature) • Discontinuation for toxicity 20% vs 10.9% These results help guide
