MedicalResearch.com Interview with: Dr. Corina Dutcus MD Vice President of Clinical Research Oncology Business Group Eisai MedicalResearch.com: What is the background for this study? Would you briefly explain how lenvatinib works? Is it used for any other malignancies, ex. thyroid cancer? Dr. Corina Dutcus Response: LENVIMA (lenvatinib), discovered and developed by Eisai, is an orally available multiple receptor tyrosine kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). LENVIMA inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1-4, the platelet derived growth factor receptor alpha (PDGFRα), KIT, and RET. LENVIMA is approved in combination with everolimus for the treatment of patients with advanced renal cell carcinoma (RCC) following one prior anti-angiogenic therapy. The approved starting dose for LENVIMA is 18 mg daily. The objective of Study 218, a randomized, open-label, Phase 2 trial, was to assess whether the lower starting dose of LENVIMA (14 mg daily) in combination with everolimus (5 mg daily) would provide similar efficacy with an improved safety profile compared to the FDA-approved starting dose of LENVIMA (18 mg daily) plus everolimus (5 mg daily) in patients with advanced renal cell carcinoma (RCC) following prior treatment with an antiangiogenic therapy. In the US, LENVIMA is also indicated for:
  • the treatment of patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer (RAI-refractory DTC);
  • for the first-line treatment of patients with unresectable hepatocellular carcinoma (HCC);
  • and in combination with pembrolizumab, for the treatment of patients with advanced endometrial carcinoma that is not microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR), who have disease progression following prior systemic therapy, and are not candidates for curative surgery or radiation. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trial.

MedicalResearch.com Interview with: Adam Talenfeld, M.D Assistant Professor of Radiology Weill Cornell Medical College Assistant Attending Radiologist New York-Presbyterian Hospital. MedicalResearch.com: What is the background for this study? What are the main findings? Response: We know that renal function decreases as we age, and we know that decreased renal function is independently associated with increased mortality. This is why medical society guidelines recommend partial nephrectomy, which preserves kidney tissue and function, over radical nephrectomy for the treatment of the smallest kidney cancers, stage T1a tumors, which are under 4 cm diameter. Paradoxically, though, we know older patients are more likely than younger patients to receive radical nephrectomy for these smallest tumors, probably because it’s a simpler surgery than partial nephrectomy. Percutaneous ablation, focal tissue destruction using heat or cold emanating from the tip of a needle, is a newer, image-guided, minimally-invasive, tissue-sparing treatment for solid organ tumors. We wanted to test how well percutaneous ablation would compare to partial nephrectomy and radical nephrectomy for these smallest kidney cancers. We found that percutaneous ablation was associated with similar 5-year overall and cancer-specific survival compared to radical nephrectomy. At the same time, ablation was associated with significantly lower rates of new-onset chronic renal insufficiency and one-fifth as many serious non-urological complications than radical nephrectomy within 30 days of treatment. These were complications, such as deep venous thrombosis or pneumonia, that resulted in emergency department visits or new hospital admissions. The outcomes of percutaneous ablation compared with partial nephrectomy were somewhat less clear, though ablation was again associated with fewer perioperative complications. (more…)

MedicalResearch.com Interview with: Prof. Michael B. Atkins, MD Deputy Director, Georgetown-Lombardi Comprehensive Cancer Center William M. Scholl Professor and Vice-Chair Department of Oncology and Professor of Medicine Georgetown University Medical Center MedicalResearch.com: What is the background for this study? Response: Prior studies combining programmed death-1 (PD-1) checkpoint inhibitors with tyrosine kinase inhibitors of the vascular endothelial growth factor (VEGF)-pathway have been characterized by excess toxicity precluding further development. We hypothesized that axitinib, a more selective VEGF inhibitor would combine safely with pembrolizumab (anti-PD-1) and yield antitumour activity in treatment-naïve patients with advanced renal cell carcinoma.
