Trial Summary

What is the purpose of this trial?

This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and waste as urine. Most papillary tumors look like long, thin finger-like growths under a microscope. It is also called papillary kidney cancer or PRCC. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of cancer cells. Combination therapy with atezolizumab and cabozantinib may shrink the cancer and allow a longer survival time in patients with metastatic renal cell carcinoma.

Will I have to stop taking my current medications?

The trial requires that participants do not take certain medications, specifically strong CYP3A4 inhibitors and inducers, within 14 days before starting the trial and during the trial. If you are on these medications, you may need to stop or switch them, but the protocol does not specify about other medications.

What data supports the effectiveness of the drugs Cabozantinib and Atezolizumab for advanced kidney cancer?

Cabozantinib has been shown to help patients with advanced kidney cancer live longer without the disease getting worse compared to another drug, sunitinib. Atezolizumab, when combined with another drug, bevacizumab, has also shown benefits in patients with a specific type of kidney cancer, helping them live longer without disease progression and improving their ability to perform daily activities.

Is the combination of Cabozantinib and Atezolizumab safe for humans?

Cabozantinib, when used with other drugs like nivolumab, has shown a manageable safety profile with common side effects such as diarrhea, fatigue, and skin reactions, which can be managed with medical care and dose adjustments. Atezolizumab, used for various cancers, has also been approved with a known safety profile. While specific data on the combination of Cabozantinib and Atezolizumab is not provided, both drugs have been used safely in humans for other conditions.

How does the drug combination of Cabozantinib and Atezolizumab differ from other treatments for advanced kidney cancer?

The combination of Cabozantinib and Atezolizumab is unique because Cabozantinib is a multi-tyrosine kinase inhibitor that targets specific proteins involved in kidney cancer growth, while Atezolizumab is an immunotherapy drug that helps the immune system attack cancer cells. This combination offers a novel approach by combining targeted therapy with immunotherapy, potentially improving outcomes for patients with advanced kidney cancer.

Cabozantinib as first-line treatment in advanced renal cell carcinoma: a profile of its use. [2020] Oral cabozantinib tablets (Cabometyx®) are an important option for the treatment of advanced renal cell carcinoma (RCC). Cabozantinib is an anti-angiogenic agent and potently inhibits multiple tyrosine kinases, including those implicated in the development of RCC. The previously approved indication of cabozantinib tablets (i.e. treatment of advanced RCC following prior VEGF-targeted therapy) has been extended to include the first-line treatment of advanced RCC in treatment-naïve adults with intermediate or poor risk (EU) and all patients with advanced RCC (USA). These label extensions are based on the results of a randomized, open-label phase 2 trial, in which adults with metastatic RCC of poor or intermediate risk received targeted first-line treatment with cabozantinib or standard-of-care sunitinib. Relative to sunitinib, cabozantinib significantly prolonged median progression-free survival (primary endpoint; investigator and independent assessments), and increased the objective response rate (investigator assessment). The tolerability profile of cabozantinib is comparable to those of other tyrosine kinase inhibitors, with adverse events being manageable with medical intervention, dosage reductions, treatment interruption and/or permanent discontinuation.

Cabozantinib for the Management of Metastatic Clear Cell Renal Cell Carcinoma. [2020] Cabozantinib is a multi-tyrosine kinase inhibitor used for the treatment of various solid-organ tumours. It was recently approved as a first- and second-line therapeutic for the management of advanced/metastatic renal cell carcinoma based on the results of two randomised controlled trials. The phase III METEOR trial compared cabozantinib against everolimus as a second- or greater line therapy and found benefits in progression-free and overall survival, and the phase II CABOSUN trial compared cabozantinib against sunitinib as a first-line therapeutic and found benefits in terms of progression-free survival. This review briefly summarises how cabozantinib fits into current treatment paradigms for the management of advanced renal cell carcinoma.

Atezolizumab plus Bevacizumab Versus Sunitinib for Patients with Untreated Metastatic Renal Cell Carcinoma and Sarcomatoid Features: A Prespecified Subgroup Analysis of the IMmotion151 Clinical Trial. [2022] Patients with metastatic renal cell carcinoma with sarcomatoid features (sRCC) have a poor prognosis and have shown limited responsiveness to inhibition of the VEGF pathway. We conducted a prespecified analysis of the randomised, phase 3 IMmotion151 trial in previously untreated patients with advanced or metastatic RCC to assess the effectiveness of atezolizumab + bevacizumab versus sunitinib in a subgroup of patients with sarcomatoid features. Patients whose tumour had any component of sarcomatoid features were included and received atezolizumab + bevacizumab (n = 68) or sunitinib (n = 74). Baseline characteristics were similar between the groups. Median progression-free survival was significantly longer in the group receiving atezolizumab + bevacizumab overall (8.3 vs 5.3 mo; hazard ratio [HR] 0.52 95% confidence interval [CI] 0.34-0.79) and in the subset of patients with PD-L1-positive tumours (8.6 vs 5.6 mo; HR 0.45, 95% CI 0.26-0.77). More patients receiving atezolizumab + bevacizumab achieved an objective response (49% vs 14%), including complete responses (10% vs 3%), and reported greater symptom improvements versus sunitinib. Safety was consistent with the known profiles of each drug and with that reported in the overall safety-evaluable population of IMmotion151. This analysis supports enhanced activity of atezolizumab + bevacizumab in patients with sRCC. PATIENT SUMMARY: In this report, we looked at patients with a specific type of kidney cancer (tumours with sarcomatoid features) that has been hard to treat. A treatment with two drugs (atezolizumab and bevacizumab) appeared to help patients live longer without the disease getting worse than another drug (sunitinib) that is often used. Patients who took the two drugs also said they were better able to carry out their everyday activities than patients who took sunitinib. The combination of these two drugs may work better in patients with this type of advanced kidney cancer.

Atezolizumab plus cabozantinib versus cabozantinib monotherapy for patients with renal cell carcinoma after progression with previous immune checkpoint inhibitor treatment (CONTACT-03): a multicentre, randomised, open-label, phase 3 trial. [2023] Immune checkpoint inhibitors are the standard of care for first-line treatment of patients with metastatic renal cell carcinoma, yet optimised treatment of patients whose disease progresses after these therapies is unknown. The aim of this study was to determine whether adding atezolizumab to cabozantinib delayed disease progression and prolonged survival in patients with disease progression on or after previous immune checkpoint inhibitor treatment.

Management of adverse events associated with cabozantinib plus nivolumab in renal cell carcinoma: A review. [2023] Tyrosine kinase inhibitors have been successfully developed in combination with immune checkpoint inhibitors to treat advanced renal cell carcinoma (RCC), further advancing treatment. While safety profiles are generally manageable with combination regimens, overlapping adverse events (AEs) and immune-related AEs can make treatment more complex. The CheckMate 9ER study evaluated the tyrosine kinase inhibitor cabozantinib in combination with the anti-programmed cell death protein-1 antibody nivolumab in patients with previously untreated advanced RCC. Cabozantinib + nivolumab demonstrated superiority over sunitinib for progression-free survival, overall survival, and objective response rate. These outcomes supported the approval of cabozantinib + nivolumab as a first-line therapy for advanced RCC. The safety profile was manageable with prophylaxis, supportive care, dose holds and reductions for cabozantinib, and dose holds and immunosuppressive therapy for nivolumab. This review discusses the safety results of CheckMate 9ER and provides guidance on managing some of the more clinically relevant AEs with a focus on overlapping AEs, including diarrhea, elevated amylase/lipase, hepatotoxicity, dermatologic reactions, fatigue, endocrine disorders, and nephrotoxicity. We discuss AE management strategies (prophylaxis, supportive care, dose modification, and immunosuppressive therapy), and provide recommendations for identifying the causative agent of overlapping AEs and for consulting specialists about organ-specific immune-related AEs. Optimizing AE management can maintain tolerability and should be a priority with cabozantinib + nivolumab treatment.

Cabozantinib use in renal cell carcinoma. [2021] In the last several years, many new drugs have been approved to treat metastatic renal cell carcinoma (RCC). Cabozantinib is a novel multikinase inhibitor with activity against vascular endothelial growth factor receptor (VEGFR), proto-oncogene tyrosine-protein kinase receptor Ret and other kinases that recently joined this impressive list of approved agents. Cabozantinib is an active agent in the preclinical and clinical setting, having recently demonstrated superiority over everolimus in a blinded, randomized phase III study of patients with progressive RCC after at least one prior line of antiangiogenic therapy. This agent's toxicity profile is similar to those of other multikinase inhibitors approved to treat RCC. This review will explore cabozantinib's pharmacologic and safety profile and its preclinical and clinical activity in RCC.

Cabozantinib versus Everolimus in Advanced Renal-Cell Carcinoma. [2022] Cabozantinib is an oral, small-molecule tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor (VEGFR) as well as MET and AXL, each of which has been implicated in the pathobiology of metastatic renal-cell carcinoma or in the development of resistance to antiangiogenic drugs. This randomized, open-label, phase 3 trial evaluated the efficacy of cabozantinib, as compared with everolimus, in patients with renal-cell carcinoma that had progressed after VEGFR-targeted therapy.

Cabozantinib for the treatment of kidney cancer. [2020] Cabozantinib is a small molecule tyrosine kinase inhibitor that initially showed activity in medullary thyroid cancer and was recently approved by the Food and Drug Administration for the treatment of metastatic renal cell carcinoma after progression on first line therapy. Areas covered: In the METEOR trial, cabozantinib demonstrated significantly improved efficacy in all three endpoints; response rates, progression free survival and overall survival in a randomized trial with everolimus as an active comparator. Cabozantinib also showed activity in the front line setting in RCC within the CABOSUN trial. The study randomized untreated metastatic RCC patients to either cabozantinib or sunitinib and the former showed improved progression free survival which was the primary endpoint. The future holds promise for indications in other malignancies, given the preliminary efficacy and unique mechanism of action of cabozantinib. In this review we address the mechanism of action, pharmacodynamics and pharmacokinetics of cabozantinib, and also review the development pathway of this agent in the treatment of advanced renal cell carcinoma. The potential benefit in specific patient populations, such as poor risk patients and bone metastases subgroups is also discussed. Expert commentary: The clinical applications of cabozantinib will be addressed within the context of the current competitive therapeutic landscape of RCC.
