Nerlynx: Reducing recurrence of HER2+ breast cancer
LOS ANGELES, Calif. (Ivanhoe Newswire) – HER2-positive breast cancer is more aggressive, grows faster, and is more likely to return. That’s why women who test positive for HER2 and their doctors are excited about a new drug that could cut the risk of cancer’s return by a third.
Allison Landherr was diagnosed with stage three HER2-positive breast cancer when she was 39.
“All of a sudden, you have this cancer diagnosis, and you stop everything and just try to figure out how are you going to survive,” Landherr said.
She had surgery, chemo, radiation, and a year of Herceptin. She knew cancer returns for up to a quarter of patients after Herceptin. Then, her doctor told her about Nerlynx, a targeted therapy that works inside cancer cells and blocks growth signals from multiple pathways.
Linda D Bosserman, MD, FASCO, Medical Oncologist at City of Hope explained, “It irreversibly inactivates that and then downstream it can’t signal, so that leads to in vivo, increased cell death.”
Allison took six pills a day for a year. She also took medicine for diarrhea, the worst side effect.
“Truthfully, life went on as normal throughout the treatment,” Landherr admitted.
Doctor Bosserman says Nerlynx may not make a big difference for women in stage one. But it significantly reduced recurrence for some women with more advanced cancer.
“For women with multiple nodes positive, estrogen positive, their risk can be up in that 30 percent range, and to lower that 34 percent is a profound benefit to women,” Dr. Bosserman stated.
Allison stopped taking Nerlynx eight months ago, is cancer-free and looking ahead.
“I want to see my children thrive and become independent and see what the future holds for them,” Landherr stated.
And she’s looking forward to growing old with her husband.
Doctor Bosserman got Nerlynx for Allison by compassionate use from Puma Biomedical at City of Hope Hospital. The trial had officially ended by the time she needed it. The FDA has since approved the drug.
