💥 New Breakthrough in Lung Cancer Treatment: The Impact of Mobocertinib Withdrawal 💥

Experts caution that the discontinuation of mobocertinib, a medication used for treating a type of lung cancer that impacts non-smokers, could leave patients in the United Kingdom in a vulnerable situation.

Non-smokers with lung cancer may face changes in their treatment due to drug removal

The withdrawal from use of a crucial treatment for lung cancer could severely affect patients, U.K. experts warn.

We often associate lung cancer with smoking, but did you know that 80-90% of lung cancer cases are actually linked to smoking? That means there’s a significant number of non-smoking-related lung cancers out there. One type of non-smoking-related lung cancer is known as EGFR+ lung cancer, caused by specific nonhereditary gene mutations[^1^].

These mutations, such as EGFR 19 deletion and EGFR L858R point mutation, can lead to the development of EGFR+ lung cancer[^2^]. Unlike smoking-related lung cancers, EGFR+ lung cancers often appear in younger people and have atypical symptoms, like shoulder pain or other musculoskeletal symptoms, rather than the more common symptoms like coughing or breathlessness[^2^].

One specific mutation, known as the exon 20 insertion mutation, is responsible for up to 10% of EGFR+ lung cancer cases[^3^]. Until recently, there were no effective treatments available for this mutation in the United Kingdom. Then came the breakthrough: Mobocertinib (Exkivity), a tyrosine kinase inhibitor (TKI), received accelerated approval for the treatment of locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations[^4^].

The Importance of Mobocertinib for Lung Cancer Patients

Patients with the exon 20 insertion mutation have a poorer prognosis compared to those with other mutations[^5^]. Mobocertinib offered hope for these patients as a targeted treatment option, aside from platinum-based chemotherapy[^6^].

However, in a surprising turn of events, the manufacturers of Mobocertinib voluntarily withdrew the drug from use in the United States. Now, health authorities in the United Kingdom plan to follow suit by withdrawing it next month[^7^]. This has sparked concerns among EGFR+ campaigners, who worry that patients in the UK with this mutation will have no treatment options to extend life after chemotherapy[^7^].

In phase 3 clinical trials, Mobocertinib failed to show a significant effect on progression-free survival (PFS)[^8^]. Additionally, some patients experienced side effects, leading to dose reduction or treatment discontinuation[^8^]. These factors contributed to the withdrawal of the drug, despite the absence of significant safety concerns[^8^].

The Impact on Lung Cancer Patients in the UK

The withdrawal of Mobocertinib has left many lung cancer patients with the exon 20 insertion mutation feeling uncertain about their treatment options. They fear that without this drug, their lifespans will be reduced, and mortality rates will increase[^9^].

Despite the withdrawal, patients who were already taking Mobocertinib before its official withdrawal will still have access to the drug through a compassionate use program as long as they are deriving clinical benefit[^9^]. However, for new patients, the lack of alternative treatment options is a significant concern.

The Call for Alternative Treatments in the UK

Currently, Mobocertinib is the only treatment funded by the National Health Service (NHS) for patients with the exon 20 insertion mutation in the UK[^10^]. While there are other drugs available for this mutation, such as aminvantamab, it is only accessible privately, making it difficult for patients without private insurance or alternative means of funding[^11^].

There is a growing call for aminvantamab to be made accessible to NHS patients, as it has shown efficacy in standard practice for exon 20 patients in Europe and the USA[^12^]. The cost of the drug has been a barrier to it being licensed by NICE (National Institute for Health and Care Excellence) in the UK for NHS funding[^12^].

In situations where the withdrawal of a drug leaves a treatment gap and unmet need for patients, there should be a way to expedite the approval process for alternative treatments like aminvantamab[^13^]. This would ensure that patients are not left without options in their fight against lung cancer.

Additional Questions

1. Are there other targeted therapies available for EGFR+ lung cancer?
While targeted therapies like TKIs have shown efficacy in treating certain EGFR+ mutations, their effectiveness may vary depending on the specific mutation. It’s essential for patients to consult with their healthcare providers to explore alternative treatment options tailored to their specific mutation[^6^].

2. What are the typical symptoms of EGFR+ lung cancer?
Unlike smoking-related lung cancers, EGFR+ lung cancers often present with atypical symptoms, such as shoulder pain or other musculoskeletal symptoms. These symptoms can sometimes be mistaken for other conditions, highlighting the importance of early detection and seeking medical advice if any concerning symptoms arise[^2^].

3. Is there ongoing research for new treatments for EGFR+ lung cancer?
The field of lung cancer research is continually evolving, and scientists are continuously exploring new treatment options. Clinical trials are underway to evaluate the efficacy of various drugs and therapies for EGFR+ lung cancer, providing hope for future advancements in treatment options[^14^].

4. How can patients access potential alternative treatments like aminvantamab?
For patients interested in accessing potential alternative treatments like aminvantamab, it’s crucial to discuss options with their healthcare providers and explore resources available within the healthcare system. They may be eligible for clinical trials or compassionate use programs that provide access to experimental treatments[^11^].

5. Are there support groups or organizations that can provide assistance to patients and their families?
There are numerous support groups and organizations dedicated to providing assistance and support to lung cancer patients and their families. These groups offer a wealth of resources, including emotional support, information on treatment options, and financial assistance programs. Connecting with these organizations can provide valuable support throughout the journey of living with lung cancer[^15^].


The withdrawal of Mobocertinib has presented significant challenges for lung cancer patients with the exon 20 insertion mutation in the UK. While there is a need for alternative treatment options, patients can find solace in ongoing research and the tireless efforts of scientists to discover new and effective therapies for EGFR+ lung cancer. Until then, it is crucial for patients to work closely with their healthcare providers to explore all available treatment options and find the best course of action for their individual cases.

Investing in lung cancer research and improving access to innovative treatments will be vital in bridging the treatment gap and ensuring the best possible outcomes for lung cancer patients in the future.

🌟 Remember, you’re never alone in this battle. Reach out to support groups and organizations that can offer guidance, empathy, and valuable resources. Together, we can combat lung cancer and provide hope for a brighter future.
