FDA Approves Zykadia (Ceritinib) for ALK-Positive Lung Cancer

A second drug that specifically targets non-small cell lung cancer (NSCLC) that is positive for the ALK gene rearrangement has been approved by the US Food and Drug Administration (FDA).

The new drug, ceritinib (Zykadia, Novartis), in indicated for patients with ALK-positive NSCLC who have previously been treated with crizotinib (Xalkori, Pfizer), the first targeted agent for this patient population.

This is an accelerated approval, and comes 4 months ahead of schedule.

ALK gene rearrangement is found in about 2% to 7% of patients with NSCLC, which makes up about 85% of all lung cancer, according to the FDA announcement.

Since its launch in 2011, crizotinib has become a standard of care in this small patient population, with data showing that it doubles progression-free survival when compared with chemotherapy.

However, some patients become resistant to crizotinib, and until now, there has been no other targeted therapy to offer these patients. Zykadia (ceritinib now fills that role.

"Ceritinib represents an important treatment option for ALK-positive NSCLC patients who relapse after starting initial therapy with crizotinib," said lead investigator Alice Shaw, MD, PhD, from the Massachusetts General Hospital Cancer Center in Boston. "This approval will affect the way we manage and monitor patients with this type of lung cancer, as we will now be able to offer them the opportunity for continued treatment response with a new ALK inhibitor," she said in a statement.

The drug went through the FDA Accelerated Approval Program, which allows approval of a drug to treat a serious or life-threatening disease based on clinical data showing the drug has an effect on a surrogate end point reasonably likely to predict clinical benefit to patients. This program provides earlier patient access to promising new drugs while the company conducts confirmatory clinical trials, the agency said.

The accelerated approval was based on a clinical trial of 163 patients with metastatic ALK-positive NSCLC, who progressed on or were intolerant to treatment with crizotinib. The most common sites of metastases in the patient population studied were brain (60%), liver (42%), and bone (42%)

Results showed that about half of the participants had their tumors shrink, and this effect lasted an average of about 7.0 months, the agency noted. The overall response rate was 54.6% (95% confidence interval [CI], 47% - 62%), and the median duration of response was of 7.4 months (95% CI, 5.4 - 10.1), the company added in its press release.

Common adverse effects of Zykadia (ceritinib) include gastrointestinal symptoms, such as diarrhea, nausea, vomiting, and abdominal pain. Laboratory abnormalities, such as increased liver enzymes, pancreatic enzymes, and increased glucose levels, were also observed.

It was approved 4 months ahead of the product's prescription drug user fee goal date of August 24, the date the agency was scheduled to complete review of the drug application.

The FDA also granted Zykadia (ceritinib) Breakthrough Therapy Designation, priority review, and Orphan Product Designation. The manufacturer has demonstrated through preliminary clinical evidence that the drug may offer a substantial improvement over available therapies, the agency said. It had the potential, at the time the application was submitted, to be a significant improvement in safety or effectiveness in the treatment of a serious condition. Also, the drug is intended to treat a rare disease, it noted.

The problem with ALK-rearranged NSCLC targeted drug Zykadia (ceritinib)

Zykadia (ceritinib) being approved is a good thing as it is yet another drug that may provide good benefit for some or even possibly many people. The real question is whether it is right for a specific patient with a specific cancer. The answer to that is they don't know because they don't even bother to test for it. They simply test whether the mutation or gene structure exists in the cancer patient for which this drug might be of use. Without any other compelling testing or data on actual use and effect of the drug on that specific cancer patient the odds will always be 50/50, as it is pointed out in how we perform trial and error medicine.

The problem here isn't whether Zykadia is an effective drug or not, it's the same problem they still refuse to deal with and that is whether it is an effective drug or not for each specific patient, the whole purpose of targeted therapy. The assumption is that because you have the mutation (the specific focus) which a drug is related too, it should have some effect and does not account for anything else of which there are and has already been pointed out, seemingly limitless factors. It costs entirely too much to study and determine all of these things, they just want what they need to get approved.

It is so much more complex than that and is why Zykadia has great effect in one and little to none in another even though the tests they currently use say it should work simply because they assume it will as they have the same mutation. Truth is, without proper whole cell live assay testing done on a proper sample, the only way to know if it will work or not is trial and error, the very way they do treatment today, take the drug over a period of time and see if it is working or not. Mutation testing to find targeted drugs is good but it is only a piece to the puzzle and does not really indicate whether it will work for one patient over another with the same mutation. If it did, every single patient with the mutation would benefit exactly the same with the same drug, it simply just doesn't work like that even though that is the basis of the primary treatment assumption for all cancers and all treatments.

So, besides not approaching drug selection and treatment properly to begin with the other big factor is of course cost which many governments and insurance providers are becoming more and more unwilling to justify.

Nobody is looking for a cure, it gets thrown around a lot because that's what they all wish for. Truth is every cancer and every patient is unique so there is likely no cure-all, at least not with the knowledge they have today. We have treatments and a good focus for treatment is to turn cancer into a cronic condition which can be maintained and controlled until natural death occurs. Very slowly the focus in the US is switching to that but it will probably take some time. Disease stability is something that can be achieved if they focus on it properly and both PFS, OS and QOL are all part of the equation. PFS and OS can be definitive, QOS is subjective so very difficult to quantify properly.

Those on Xalkori (crizotinib) but their NSCLC worsened or cannot tolerate taking it?

Zykadia (ceritinib) is a new FDA-approved prescription medicine that is used to treat people with non-small cell lung cancer (NSCLC) that:

* Is caused by a defect in a gene called anaplastic lymphoma kinase (ALK), and

* Has spread to other parts of the body, and

* Who have taken the medicine crizotinib, but their NSCLC worsened or they cannot tolerate taking crizotinib

The effectiveness of Zykadia (ceritinib) is based on response rate and duration of response. There are no data demonstrating an improvement in patient reported outcomes or survival with Zykadia (ceritinib).

If you or a loved one has been diagnosed with ALK+ NSCLC and have already received an ALK inhibitor, ask your doctor if Zykadia (ceritinib) may be right for you. Make an appointment to talk to your doctor today.

Now that it's FDA approved, phenotype assayists are ordering some and building up a database, to give it to the right patients. There is entirely too much trial-and-error giving so much side effects to the wrong patients.
