 in the community setting, Subbiah notes. This now demonstrates proof of principal for selective RET inhibition, so we need to know when patients will receive the most benefit from specific RET targeting, which is upfront, in Subbiah’s personal opinion.

Selpercatinib Data Underscore Value of Precision Medicine in RET-Driven Lung Cancer

Subbiah’s main message is that NSCLC is the poster child of precision oncology. The more physicians test for, the more we find. In order to win the war against lung cancer, Subbiah says we need to completely understand the disease, and comprehensive next-generation sequencing that includes all fusions and mutations is the first step.

Genomic Testing Is Necessary in Non-Small Cell Lung Cancer

Vivek Subbiah, MD, of the Department of Investigational Cancer Therapeutics, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, discusses the implications of the phase 1/2 LIBRETTO-001 study, which evaluated selpercatinib (formerly known as LOXO-292; Retevmo) as treatment of patients with 

 fusion-positive non–small cell lung cancer (NSCLC).

Durable efficacy was observed with selpercatinib in patients with 

 fusion-positive NSCLC who had been previously treated with platinum-based chemotherapy, as well as intracranial activity. Fewer than 15% of patients experienced grade 3 or higher adverse events, Subbiah notes.

Interestingly, selpercatinib induced durable efficacy in previously untreated patients as well, Subbiah says. It is estimated that 

 occurs in about 10,000 new cases every year, which makes up about 1% to 2% of lung cancer burden globally. The 

 fusion was only identified in 2012, and the available treatment options were limited to multikinase inhibitors that had some anti-

Selpercatinib gives patients the gift of time, and the antitumor activity in this study was also observed regardless of prior exposure to immune checkpoint inhibitors. The safety profile also suggests that multiple administrations is feasible in most patients. It is critical to identify these patients who are eligible for a RET inhibitor, Subbiah concludes.

Selpercatinib Induced Durable Efficacy in RET Fusion-Positive NSCLC

Vivek Subbiah, MD, of the Department of Investigational Cancer Therapeutics, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, discusses the frontline therapeutic options for patients with renal cell carcinoma (RCC).

In the first-line setting for this disease, the agents available in the United States include sunitinib (Suntent), pazopanib (Vortriant), tivozanib (Fotivda), and bevacizumab (Avastin) plus interferon. Tivozanib is also approved in Europe in the first line. Subbiah says that more and more frequently, immunotherapy data has been investigated, such as the checkpoint combination therapy of ipilimumab (Yervoy) and nivolumab (Opdivo).

Over the last 5 years, there has been amazing activity in the immunotherapy space, according to Subbiah. At this point, based on approvals and follow-up data, the checkpoint inhibitor combination of the CTLA4 antibody and PD-1 inhibitor has demonstrated the best data so far in the first line setting for patients with RCC.

Although these regimens are available, not all patients are being cured with these treatments. Most patients have an improvement in progression-free survival, but there is still an unmet need for patients in the second-, third-, and fourth-line setting.
