That’s the word from Virginia Kaklamani, MD, from the University of Texas Health Sciences Center San Antonio. Dr. Kaklamani, a professor of medicine in the division of hematology/oncology, is codirector of the meeting that runs online Dec. 8-11.
If the new trial sounds familiar, that’s because it’s a lot like the TAILORx trial, the results of which were first presented in 2018 and have changed practice in women with early-stage disease and no lymph node involvement.
“This is the lymph-node positive TAILORx. It’s extremely important,” Dr. Kaklamani said in an interview, adding that both trials involved women with hormone receptor (HR)–positive, HER2-negative disease.
If the RxPONDER trial shows similar outcomes between women randomized to adjuvant endocrine therapy alone versus endocrine therapy plus chemotherapy, then clinicians “can potentially avoid giving chemotherapy to a large number of women who are currently receiving it,” she explained.
Because women with nodal involvement (one to three positive axillary nodes) are at a higher risk of recurrence, RxPONDER may provide needed insight on the management of these types of breast cancers, Dr. Kaklamani suggested.
Both trials have used the 21-tumor gene expression assay (Oncotype Dx) to determine recurrence-risk status.
Dr. Kaklamani also spotlighted the phase 3 CONTESSA trial (abstract GS4-01) in 600+ patients with locally advanced or metastatic breast cancer that is HR positive and HER2 negative and has been previously treated with a taxane.
The trial features an experimental oral taxane, tesetaxel. The primary objective is to compare the efficacy of tesetaxel plus a reduced dose of capecitabine (Xeloda) versus the approved dose of capecitabine alone. Presented data will include progression-free survival results, indicating about a 3-month PFS advantage with tesetaxel, which is taken once every 3 weeks.
“Oral drugs are convenient for patients and, despite limitations, they are, all in all, a revolution in cancer treatment,” noted Dr. Kaklamani, adding that they beneficially eliminate the need for time-consuming infusions and related clinic visits as well as drug ports.
It will be interesting to see what Steven Vogl, MD, a private practitioner in New Yorky, has to say about CONTESSA and the rest of the SABCS.
He is usually a commentator from the meeting floor, whose self-introduction, “Vogl, New York,” is well known to perennial meeting attendees, according to a profile piece published some years ago.
This year the medical oncologist will also serve as the chair of the “View from the Trenches” session, which is devoted to summarizing the meeting’s most important findings for everyday practitioners.
A number of years ago, Dr. Vogl proposed the idea of this where-the-rubber-meets-the-road session to SABCS meeting planners, which they then adopted. This year, Dr. Kaklamani invited Dr. Vogl to run the session and he accepted.
Dr. Vogl is a “really smart guy who is always right on” with his comments and questions, and he will be the first-ever independent, community-based oncologist to chair a meeting session, said Dr. Kaklamani.
