The KOL Pulse Daily Digest of what verified physician (KOL) voices are discussing on X across lung, breast, GI, GU, multiple myeloma, and leukemia & lymphoma, ranked by engagement over the last 48 hours.
Stephen Liu flagged the final Phase III SKYSCRAPER-01 readout in JCO: adding the anti-TIGIT antibody tiragolumab to atezolizumab did not significantly improve PFS or OS in first-line PD-L1-high NSCLC, despite an encouraging Phase II. The miss reopened KOL debate over whether the TIGIT class can translate — and whether differently engineered, Fc-active anti-TIGIT antibodies might still succeed.

“Phase III SKYSCRAPER-01 @JCO_ASCO: 1L atezolizumab +/- tiragolumab (anti-TIGIT) for PDL1 high NSCLC (n=521). Adding tiragolumab did not significantly improve PFS (7m vs 5.6m, HR 0.78, ns) or OS (23.1m vs 16.9m, HR 0.87, ns), despite promising phase II.”

“The TIGIT chapter is becoming a story to learn. So far it has been mostly of Ph3 failing the ph2 promises. Now, differently designed TIGITS may change it. Fc-mediated differences in T cells might be the dealbreaker. Do you see any encouraging signs with donvalanimab?”

New publications include a 5-year quality of life study from the SUPREMO trial, which examined chest wall radiotherapy in intermediate-risk breast cancer. Additionally, a prospective study in early breast cancer linked greater adiposity with worse diastolic function.

“In advanced #TNBC and #Her2+ breast cancer, for many it’s not an “if”brain metastases will occur, it’s a “when.” Catching brain disease early can preserve cognitive function and decrease rates of catastrophic complications (herniation/death).”

“Brain imaging screening in #MetastaticBreastCancer: Is it time to rethink clinical guidelines and practice? In this recent editorial Drs. Sarah Sammons, Nayan Lamba and Nancy Lin present some compelling reasons: 🔦Screening for #BrainMetastasis (BM) is associated with clinically relevant rates of detection of asymptomatic disease 🔦Screening for #BrainMets leads to diagnosis of smaller and fewer lesions, prior to the development of neurologic symptoms 🔦Advanced radiation oncology techniques are safer and more effective for smaller #CNS system lesions 🔦Treating patients with asymptomatic/occult lesions may result in better outcomes 🔦Advances in systemic treatments have expanded treatment options and improved outcomes for patients with BM, particularly in HER2+ #MBC 🔦The identification of asymptomatic BM on brain imaging scans can lead to changes in treatment strategy.”

The RADICAL (A031801) trial found that adding radium-223 to cabozantinib did not improve symptomatic skeletal event-free survival in patients with metastatic RCC and bone metastases. In urothelial cancer, retrospective data for patients progressing on enfortumab vedotin plus pembrolizumab showed a 49% ORR to second-line platinum chemotherapy, with a median duration of response of 5.2 months. Additionally, a UNITE Consortium study demonstrated prognostic value for longitudinal ctDNA monitoring during EV ± pembrolizumab therapy.

“In conclusion, the addition of radium-223 to cabozantinib did not improve symptomatic skeletal event-free survival in patients with metastatic RCC and bone metastases.”

Separately, the myeloma/hematology community is revisiting the ENDURANCE trial to discuss the standard of care for maintenance therapy duration.

“WHY do +5, +9, and +15 seem to be the most common trisomies in multiple myeloma? The answer may have as much to do with assay design as with biology.”
