Atezolizumab Articles

In November 2016, the results of a phase III clinical trial with the protein cell death (PD)-1 inhibitor pembrolizumab for second-line treatment of metastatic urothelial carcinoma were published and showed an overall survival benefit in comparison with conventional chemotherapy with vinflunine, docetaxel, or paclitaxel.

The first-line therapy of metastatic bladder cancer (urothelial carcinoma, UC) depends on whether a patient is cisplatin-fit or not. Cisplatin-fit patients should be treated with the standard chemotherapy protocol GC (gemcitabine/cisplatin) or alternatively MVAC (methotrexate/vinblastine/doxorubicin/cisplatin).

Despite initial promising results, the IMvigor211 clinical trial failed to demonstrate an overall survival (os) benefit for atezolizumab compared with chemotherapy as second-line treatment for metastatic bladder cancer (mbc).

To determine which of the approved immune checkpoint inhibitors is the optimal treatment in metastatic urothelial bladder cancer.

Only the pivotal Phase III trials of second-line metastatic urothelial bladder cancer were included in this network meta-analysis.

Renal cell carcinoma is a common malignancy of the genitourinary system and is the eight most common cancer type in the United States. The overall incidence of renal cell carcinoma appears to be increasing but death rates have been declining.

Urothelial carcinoma (UC) is the second most common malignancy of the genitourinary system and the sixth most common cancer in the United States. The overall incidence of UC appears to be on the decline, but death rates have remained stable.

The incidence of kidney cancer is increasing; it could be counteracted with new ways to predict and detect it. We aimed to implement an artificial neural network in order to predict new cases of renal-cell carcinoma (RCC) in the population using population rate, obesity, smoking incidence, uncontrolled hypertension, and life expectancy data in the United States.

Introduction: The therapeutic landscape of renal cell cancer has evolved rapidly over the past 2 years with nivolumab and ipilimumab for patients with metastatic disease and an intermediate or poor prognosis, in the first line setting.

Until recently, there has been little advancement in the management of invasive and metastatic urothelial cancer in over 30 years, and outcomes with cisplatin-based chemotherapy remain unchanged. Inhibitors targeting PD-1 signaling on cytotoxic T-cells have revolutionized bladder cancer therapy leading to durable responses.

Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies in patients with locally advanced or metastatic platinum-resistant urothelial carcinoma.

To compare the real-life experience and data of clinical trials on ATZ treatment in metastatic urothelial carcinoma.

Metastatic bladder cancer is an aggressive malignancy with a poor prognosis when presenting with advanced stage. Cisplatin-based therapy has been the mainstay of first-line treatment but therapy in second-line setting has been an unmet medical need for decades.

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.

In recent years, immunotherapy has come to the forefront as a major development in cancer treatment. Evasion of the immune system by tumor cells has been identified as one of the hallmarks of cancer and multiple therapies have been developed to counter this process.

There has been significant progress in the treatment of patients with advanced clear cell renal cell carcinoma (ccRCC), with improved knowledge of disease biology and the introduction of targeted agents and immunotherapies.

Advanced urothelial carcinoma (aUC) has long been treated preferably with cisplatin-based chemotherapy, but many patients are cisplatin-ineligible whereas for those who progress on a platinum-based regimen treatment options are limited.

Until recently in the United States, no products were approved for second-line treatment of advanced urothelial carcinoma. On May 18, 2016, the U.S. Food and Drug Administration approved atezolizumab for the treatment of patients with locally advanced or metastatic urothelial carcinoma whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.

A number of PD-1/PD-L1 inhibitors have recently been approved for use in patients with locally advanced or metastatic urothelial carcinoma (UC) on the basis of results from several clinical trials.

To review the evidence from these trials and consider what it means for the use of these drugs in first-line and post-platinum settings in real-life clinical practice.

A number of immune checkpoint inhibitors (ICIs) have been approved as first-line therapy in case of cisplatin-ineligible patients or as second-line therapy for patients with metastatic urothelial carcinoma (mUC) of the bladder.

Treatment of cancer patients involves a multidisciplinary approach including surgery, radiotherapy, and chemotherapy. Traditionally, patients with metastatic disease are treated with combination chemotherapies or targeted agents.

The activity of PD-1/PD-L1 inhibitors in the treatment of advanced bladder cancer (BC) is promising for many patients. However, a subset of patients do not benefit from treatment, thus leading to an effort to better identify predictive molecular biomarkers of response.

To provide a critical literature review on state of the art and novel strategies in the field of neoadjuvant treatments for muscle-invasive bladder cancer (MIBC).

a nonsystematic literature review was performed using PubMed, Scopus and Clinical Trials.

Muscle invasive bladder cancer (MIBC) is difficult to manage for patients who progress during or after initial chemotherapy regimens. Current regimens offer low response rates with high toxicities. The advent of immune checkpoint inhibitors may represent a new opportunity for effective management of these patients.

PD-1 and PD-L1 act to restrict T cell responses in cancer and contribute to self-tolerance. Consistent with this role, PD-1 checkpoint inhibitors have been associated with immune-related adverse events (irAEs), immune toxicities thought to be autoimmune in origin.

Atezolizumab, a humanised monoclonal antibody targeting PD-L1, is approved for locally advanced/metastatic urothelial carcinoma. SAUL evaluated atezolizumab in a broader, pretreated population, including patients ineligible for the pivotal IMvigor211 phase 3 trial of atezolizumab.

Metastatic urothelial carcinoma of the bladder is an aggressive malignancy with poor prognosis, reflecting a lack of effective systemic therapies. The current standard of care includes multiagent platinum-based chemotherapy; however a majority of patients do not respond to treatment and most eventually succumb to disease.

Bladder urothelial cancers remain an important urologic cancer with limited treatment options in the locally advanced and metastatic setting. While neoadjuvant chemotherapy for locally advanced muscle-invasive cancers has shown overall survival benefit, clinical uptake in practice have lagged behind.

There are limited data on toxicity and surgical safety associated with neoadjuvant programmed death ligand 1 (PD-L1) inhibitors prior to radical cystectomy (RC) in patients with muscle-invasive bladder cancer (MIBC).
