How does NERLYNX work?

NERLYNX is a small molecule targeted therapy that works inside your cells and helps stop HER2 protein signals.

NERLYNX in women with early-stage and metastatic HER2+ breast cancer

In early-stage HER2+ breast cancer

What should I know about how NERLYNX was studied?

NERLYNX was studied in a phase 3 clinical trial called ExteNET. The safety and effectiveness of NERLYNX were evaluated over 2 years in women with early-stage HER2+ breast cancer.

34 percent lower risk of recurrence in early-stage HER2+ breast cancer clinical trial

Who was in the study?
The study included 2,840 women with either hormone receptor–positive (HR+) or hormone receptor–negative (HR−) early-stage HER2+ breast cancer. All women had previously completed trastuzumab-based treatment.

What were the treatment groups in this study?
Those in the study were randomly assigned to a treatment group: 1,420 received NERLYNX and 1,420 received placebo (an inactive substance that looked the same as and was given the same way as NERLYNX). The effects of NERLYNX were compared to the effects of the placebo.

In this clinical study, NERLYNX reduced the risk of recurrence by 34% at 2 years. This was the primary endpoint of the trial.

In absolute numbers, 94.2%  of the women (1,338 out of 1,420) who took NERLYNX in the study did not have cancer return after 2 years, compared to 91.9% of the women (1,305 out of 1,420) who took placebo.

With NERLYNX, you may help further reduce the risk that your HER2+ breast cancer will return.

Individual results may vary.

Talk to your doctor for more information on this data.

Is there any other data on NERLYNX to ask my doctor about?

After the 2-year analyses, 75% of the women (2,117 out of 2,840) agreed to continue being evaluated. The 5-year analyses showed a similar reduction in risk of recurrence.

NERLYNX was studied in people with HER2+ breast cancer who were HR+ as well.

The 5-year analyses looked at 1,334 of the women with HR+ breast cancer. Of these women, 670 started with NERLYNX and 664 started with placebo within 1-year of treatment with trastuzumab.

Most of these women took endocrine (hormone) therapy while on NERLYNX.

90.8% of the women (608 out of 670) in the NERLYNX group did not have their cancer return after 5 years, compared to 85.7% of the women (569 out of 664) who took placebo. This resulted in a 42% reduction in the risk of recurrence in these women with HER2+ HR+ early-stage breast cancer.

The analysis for reduction in risk of recurrence for patients with HR+ at 5-years was done after the study was completed. It is important that you know no conclusions can be drawn from this analysis.

Individual results may vary.

Talk to your doctor for more information on this data.

Is there more about the 5-year special analysis that I should know about?

This 5-year analysis also observed a 59% reduction in the risk of central nervous system (CNS) metastases among women with early-stage HER2+ HR+ breast cancer who started NERLYNX within 1 year of treatment with trastuzumab. A CNS metastasis is cancer that has spread to parts of the CNS, such as the brain or spinal cord.

In absolute numbers, 98.4% of the women (659 out of 670) who took NERLYNX did not experience a CNS recurrence or death from any cause, compared to the 95.7% of the women (635 out of 664) who took placebo.

The analysis for reduction in risk of developing CNS metastasis at 5-years was done after the study was completed. It is important that you know no conclusions can be drawn from this analysis.

Individual results may vary.

I have early-stage HER2+ breast cancer. How do I take my NERLYNX?

NERLYNX is an oral medicine that you take once a day at home. Talk to your doctor about the correct dosage for you. Your doctor may start you off with a lower dose of NERLYNX and then gradually increase to your full dosage.

Here’s an example of what dose escalation with NERLYNX may look like:

Your doctor may also prescribe you an antidiarrheal such as loperamide when you start treatment and then as needed. Talk to your doctor about how much and how often to take this medicine. Take a look at our Antidiarrheal Support Program to see if it could help you.‡

What side effects could I experience?

Diarrhea is the most common side effect of taking NERLYNX, and can be severe. Diarrhea may lead to loss of too much body salt and fluid, which can cause dehydration.

Call your doctor right away if you have severe diarrhea or experience diarrhea along with weakness, dizziness, or fever.

NERLYNX may cause other serious side effects including liver problems. NERLYNX can also harm your unborn baby. You should use effective birth control during and for at least one month after treatment.

Here are some other commonly reported side effects when NERLYNX is used alone to treat early-stage HER2+ breast cancer:

  • Nausea
  • Stomach-area (abdomen) pain
  • Tiredness
  • Vomiting
  • Rash
  • Dry or inflamed mouth, or mouth sores
  • Decreased appetite
  • Muscle spasms
  • Upset stomach
  • Nail problems including color change
  • Dry skin
  • Swelling of your stomach-area
  • Nosebleed
  • Weight loss
  • Urinary tract infection

These are not all of the possible side effects of NERLYNX. Tell your healthcare provider if you have any side effects that bother you or that does not go away. You may report side effects to FDA at 1-800-FDA-1088.

Please see Important Safety Information below.

With metastatic HER2+ breast cancer

Take a stand against progression

“Metastatic” means that the cancer has spread beyond the breast and nearby lymph nodes to other parts of the body. NERLYNX plus capecitabine (an oral chemotherapy) can be taken to help prevent advanced or metastatic HER2+ breast cancer from spreading further.

Who is NERLYNX right for?

If you've already been treated with 2 or more HER2-directed therapies for metastatic breast cancer (like trastuzumab, T-DM1, and/or pertuzumab), NERLYNX plus capecitabine may be right for you.

What should I know about the benefits of NERLYNX plus capecitabine?

NERLYNX was studied in a phase 3 trial examining the safety and effectiveness of NERLYNX in combination with capecitabine vs lapatinib plus capecitabine. The clinical trial included 621 people with metastatic HER2+ breast cancer who had previously been treated with 2 or more HER2-directed therapies.

24 percent reduced progression metastatic HER2+ breast cancer trial

In a clinical study, NERLYNX plus capecitabine reduced the risk of progression by 24%.

29% of the women (89 out of 307) in the NERLYNX + capecitabine group did not see their cancer progress over 1 year compared to 15% (47 out of 314) people in the lapatinib + capecitabine group.

Individual results may vary.

Talk to your doctor for more information on this data.

8.5 months longer response to treatment in metastatic HER2+ breast cancer trial

In the clinical trial, NERLYNX also gave people a longer response to treatment compared with lapatinib plus capecitabine.*

*Median of 8.5 months compared to 5.6 months for those taking lapatinib. The 8.5- and 5.6-months durations were calculated only from the percentage of people that responded to therapy (32.8% in the NERLYNX group vs 26.7% in the lapatinib group).

How do I manage diarrhea?

Diarrhea is a common side effect of NERLYNX, but it can also be severe. Diarrhea may lead to loss of too much body salts and fluid, which can cause dehydration.

For patients with early-stage HER2+ breast cancer, your doctor may start you with a lower dose and slowly increase the dose until you are taking the recommended dosage of 6 pills a day. This can help you adjust to NERLYNX by managing this side effect.

Your healthcare provider may prescribe antidiarrheals as needed. Take antidiarrheals exactly as your healthcare provider tells you. Call your healthcare provider right away if you have severe diarrhea or if you have diarrhea along with weakness, dizziness, or fever.

NERLYNX can cause other side effects, including serious side effects. Please see below for Important Safety Information and Patient Information.

Working with your healthcare team

Side effects can occur with NERLYNX. But there are steps you can take to help manage the side effect of diarrhea and see your treatment through.
