Additional Analysis of Real-World Data Confirms Sequential Gilotrif Followed by Osimertinib Provided a Median OS of Nearly 4 Years in US Patients with EGFR+ NSCLC

Ridgefield, Conn., August, 10, 2020 – Boehringer Ingelheim today announced a new analysis from the GioTag study, which showed that sequential Gilotrif® (afatinib) and osimertinib contributed to a median overall survival (OS) of nearly four years (47.6 months) among U.S. patients (129) with epidermal growth factor receptor mutation-positive (EGFR M+) non-small cell lung cancer (NSCLC) and the common resistance mutation, T790M. These findings are consistent with the global primary analysis of the GioTag study, as well as a separate, interim U.S. analysis.

GioTag is a real-world retrospective, observational study which assessed the impact of first-line treatment with afatinib followed by osimertinib in Del19/L858R EGFR M+ non-small cell lung cancer patients with acquired T790M mutations, the most common mechanism of resistance to first- and second-generation EGFR tyrosine kinase inhibitors (TKIs). This analysis looked at outcomes in the subgroup of patients (129) from the United States. Final analysis for the full GioTag patient population is expected to be published later this quarter.

“Developing resistance to EGFR TKIs is, unfortunately, an expected outcome for many people with this specific lung cancer, and strategies for sequencing treatments continue to evolve with the use of TKIs in clinical practice,” said Balazs Halmos, M.D., Chief of Thoracic/Head and Neck Oncology at Montefiore Medical Center. “These real-world data provide further insight into the overall survival associated with afatinib and subsequent osimertinib treatment and reinforce that previous findings may have application in the U.S. treatment setting for patients with T790M acquired resistance.” 

The afatinib-osimertinib sequence was associated with a combined median time on treatment (time to treatment failure; TTF) of 28.4 months overall. Similar TTF was also observed across several subgroups, including patients with EGFR Del19-positive disease (30.3 months), patients with ECOG PS 0/1 (32.7 months), and in patients ≥65 years of age (34.1 months).

In the most recent analysis, median time on afatinib was 11.3 months (90% CI: 10.3–12.0) and 15.0 months (90% CI: 13.4–16.4) for osimertinib.

Bjoern Rueter, M.D., Therapeutic Area Head Oncology, USA, at Boehringer Ingelheim, said, “These real-world data offer additional evidence that afatinib prior to osimertinib may be an important consideration for patients with EGFR mutation-positive non-small cell lung cancer. Cancer can take away so much, and understanding strategies such as treatment sequencing is one way Boehringer Ingelheim is taking cancer on.”

The U.S. data were sourced from chart review and electronic records of consecutive patients treated at U.S. treatment centers between December 28, 2017, to May 31, 2018. Previous interim analyses published in Future Oncology indicated that sequential afatinib and osimertinib was associated with encouraging time on treatment and overall survival in patients with EGFR T790M-positive NSCLC, particularly in patients with Del19 mutation.

What Is Gilotrif?

Gilotrif is a prescription medicine that is used to treat people with non-small cell lung cancer (NSCLC) that:

  • has certain (non-resistant) abnormal epidermal growth factor receptor (EGFR) gene(s). Your healthcare provider will perform a test to make sure that Gilotrif is right for you.
  • has spread to other parts of the body (metastatic), and
  • has not been previously treated for metastatic lung cancer

It is not known if Gilotrif is safe and effective in treating people with lung cancer that has resistant abnormal EGFR genes.


is used to treat people with squamous cell lung cancer that:

  • has spread to other parts of the body, and
  • has been previously treated with chemotherapy that contains platinum.

It is not known if Gilotrif is safe and effective in children.

Please see Prescribing Information and Patient Information.

Important Safety Information

Before you take Gilotrif, tell your doctor if you:

  • have kidney or liver problems
  • have lung or breathing problems other than lung cancer
  • have a history of an ulcer, a tear (perforation) in your stomach or intestine, or diverticular disease (inflammation) in parts of your large intestine
  • have a history of severe dry eye or any other eye problems. Tell your doctor if you wear contact lenses.
  • have heart problems
  • have any other medical conditions
  • are pregnant or plan to become pregnant. Gilotrif can harm your unborn baby.
    • Females who are able to become pregnant should use effective birth control during treatment with Gilotrif and for at least 2 weeks after your last dose of GILOTRIF. Talk to your doctor about birth control methods that may be right for you.
    • Tell your doctor right away if you become pregnant or think you are pregnant during treatment with Gilotrif.
  • are breastfeeding or plan to breastfeed. It is not known if Gilotrif passes into your breast milk. Do not breastfeed while taking Gilotrif and for 2 weeks after your last dose of Gilotrif. Talk to your doctor about the best way to feed your baby if you take Gilotrif.

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Gilotrif may affect the way other medicines work, and other medicines may affect the way Gilotrif works. Taking certain medicines with Gilotrif may increase your risk of developing a tear (perforation) in your stomach or intestine.

What to avoid while taking Gilotrif
Limit your time in the sun. Gilotrif can make your skin sensitive to sunlight. You could get or have worsening rash or acne. You could get a severe sunburn. Use sunscreen and wear a hat and clothes that cover your skin if you have to be in sunlight during treatment with Gilotrif.

Gilotrif may cause serious side effects, including:

  • Diarrhea. Diarrhea is common with Gilotrif and may sometimes be severe. Severe diarrhea can cause loss of body fluid (dehydration) and kidney problems that can sometimes lead to death. During your treatment with Gilotrif, your doctor should prescribe medicines to treat diarrhea. Take this medicine exactly as your doctor tells you to. Tell your doctor if you have diarrhea. Get medical attention right away if your diarrhea does not go away or becomes severe.

Take medicines to help skin reactions exactly as your doctor tells you to. Get medical attention right away if you develop severe skin reactions such as peeling or blistering of the skin, or blisters in your mouth.
  • Lung or breathing problems. Gilotrif may cause inflammation of the lung that may lead to death. Symptoms may be similar to those symptoms from lung cancer. Tell your doctor right away if you have any new or worsening lung problems, or any combination of the following symptoms: trouble breathing or shortness of breath, cough, or fever.
  • Liver problems. Gilotrif can cause liver problems that can sometimes lead to death. Tell your doctor right away if you have any symptoms of a liver problem which may include:

    • swelling of your ankles, feet, or legs
    • feeling that your heart is pounding or racing (palpitations)
    • sudden weight gain

Your doctor may change your dose, temporarily stop or permanently stop treatment with Gilotrif if you have certain side effects.

The most common side effects of Gilotrif include diarrhea, rash, acne, mouth sores, nail inflammation, dry skin, decreased appetite, nausea, vomiting, and itching.
