Dr P Hillmen

We have some members who are in this important CLARITY Study in UK.

CLARITY is a phase II trial that combined ibrutinib with venetoclax in patients with relapsed or refractory CLL. The primary end point was eradication of MRD after 12 months of combined therapy.

In 53 patients after 12 months of ibrutinib plus venetoclax, MRD negativity (fewer than one CLL cell in 10,000 leukocytes) was achieved in the blood of 28 (53%) and the marrow of 19 (36%). Forty-seven patients (89%) responded, and 27 (51%) achieved a complete remission. After a median follow-up of 21.1 months, one patient progressed, and all patients were alive.

This is for R/R patients, should be much better for first line treatment :) :) :) :)

I was reading something where a trial had a 100% response rate, I can't remember what it was. I think it was Ibruitinib and FCR.

Yep, I think that was first line.

And me ! 🙂

Great news!

If this combination is available and I realize that is a big if, is Ibrutinib and Ventetoclax now recognized as the best treatment for R/R CLL/SLL after having been treated with chemo? When might this combination be approved by the FDA entities in the various countries throughout the world?

Thanks

As far as I am aware this combination is only available in clinical trials at the moment and the data/results are too immature to determine what the long term results are like.

Once there is enough data showing clinical effectiveness and cost effectiveness then countries start to look at approving it by their regulatory bodies.

USA will probably be the first country in the world, they usually are.

It seems the data to support the combination’s adoption is rapidly accumulating. What is your best guess as to when it becomes available in the US? 2-3 years?

I was going to ask the same question. Can a phase II trial in the USA result in approval?

There are phase III combo trials running now, my husband is in one for treatment naïve. I think phase II just moves it along to phase III.

Inspiring!
