My name is Francesca Guy and I work in the University Hospital in Torino, Italy. Here at ASCO 2019, I presented as the behalf of the investigators of the Torino group, the results of the FORTE study, which is a randomized study for newly diagnosed patients eligible for transplant.

In this analysis of the study, we focused on two of the three arms of the trial. And we compared it to the outcome to patients randomized to induction with KRd, followed by transplant and KRd consolidation versus continuous treatment with KRd for a total of 12 cycles. We thought at the end of this therapy that the rate of response as well as the rate of minimal residual-negativity, sensitivity 10-5, was comparable between to the overall population of the patients in the two arms. It was comparable between the two arms, also in standard-risk and high-risk patients. 

Then we looked at how many patients maintained for at least one year, MRD-negativity. And we saw that 90% of patients receiving transplant maintained MRD-negativity for one year. Where 78% of patients who did not receive transplant maintained MRD-negativity.

This difference in the rate of patients have enough persistent minimal residual disease negativity of one year was particularly evident in high-risk patients, because high-risk patients receiving a transplant, 90% of them have minimal residual negativity maintained for one year versus 72% of patients who did not receive a transplant.

We also look at the rate of early relapse in the two arms – that is rate of relapse within 18 months from the randomization to treatment.

We saw data – the number of patients relapsing within 18 months was almost doubled in patients that did not receive transplant versus patients who did receive a transplant. But the majority of them were high-risk patients and were high-risk patients that did not get into MRD-negativity. 

From these results, we can conclude that both KRd with transplant and KRD without transplant are highly effective in using high-quality -----, however, the rate of persistence one-year MRD-negativity is higher with transplant, and this is problem explains, since the difference is particularly evident in high-risk, this explains why transplant is of benefit at present in the trial, in particular with patients with high-risk disease.

We need a longer follow-up to analyze the progression-free and overall survival data
 

Conclusions

KRd-ASCT-KRd and KRd12 were equally effective in inducing high-quality responses, with about 50% of high-risk pts achieving MRD negativity. In high-risk patients, ASCT reduced the risk of early relapse.
