Yousef Zakharia, MD, clinical associate professor of internal medicine at the University of Iowa, Holden Comprehensive Cancer Center, discusses the next steps after the phase 1 trial (NCT02535533) of seleno-L-methionine (SLM) in combination with axitinib (Inlyta) as treatment of adult patients with previously treated or relapsed clear cell renal cell carcinoma (ccRCC).
Zakharia says that 1 of the observations they had while investigating this clinical trial was that the higher the blood concentration was with SLM, the better response patients had. Although this was a small cohort of patients, the investigators amended the protocol in the study to allow patients with ccRCC to be treated based on their body surface area, and this topic is still ongoing among the authors.
If they continue to see efficacy in the phase 1 data, the next step will be to start a randomized clinical trial of axitinib as the standard of care and the combination of axitinib and SLM in patients with advanced metastatic ccRCC, according to Zakharia.
