With the success of regorafenib (Stivarga) in the phase III RESORCE trial and the promise of immunotherapy agents such as nivolumab (Opdivo), hepatocellular carcinoma (HCC) seems to be coming into a new era of therapeutic development after almost a decade of failed trials.

, Singal, associate professor, UT Southwestern Medical Center, discussed the recent successes in the HCC treatment landscape and the challenges that still remain.

OncLive: Sorafenib has been established as a frontline therapy for nearly 10 years, do you see this changing in the near future?

Singal: I think it is an exciting time for HCC. Sorafenib (Nexavar) has been the only agent we have had in a decade. When it first came out, we thought that there would be something right around the corner, but then all we had was negative trial after negative trial. I think this is the first time in HCC that we are starting to see truly promising phase II data. We will see what the phase III data show in the next year or 2, but I think that this is a time where we will see a lot of progression in terms of new therapies becoming available.

We just had our second positive trial, with regorafenib showing benefit as a second-line agent. I think we are going to see more and more new drugs coming to the market. So, it will be an interesting time to be involved in the field, as we may go from 1 agent to potentially multiple in a very short period of time.

How has regorafenib impacted the field?

The RESORCE trial evaluated regorafenib versus placebo as a second-line therapy and showed a significant survival benefit in these patients. It is important, clinically, because it was an unmet need—we did not really have anything for these patients who had progressed on sorafenib. I think that what was most surprising was the degree of survival benefit in this very difficult to treat patient population, which I think speaks to not only the drug itself, but also how these patients were selected.

Do you believe there is a future for immunotherapy in HCC?

Yes, I think those are some of the most promising medications. The most exciting part of this is that we are seeing some partial responders and even some complete responders. To offer patients with advanced tumors a good chance with this is really exciting. I think you already are seeing excitement not only among providers, but among patients, with the possibility of immunotherapy. We are going to see a lot more solid phase II data coming out at the next few meetings and some early phase III results.

What is the biggest challenge in treating HCC?

I think the biggest thing that I see as a limitation in this field is the continued high proportion of patients who are diagnosed at a late stage. The possibility of new agents may shift that toward having slightly better survival but I do not think it will be anything close to what we have with curative therapies. What is frustrating is that HCC surveillance is fairly easy to do, it is just not being done. If we were able to increase rates of surveillance, we would dramatically improve prognosis.
