Article Synopsis
  • Death rates for non-small cell lung cancer (NSCLC) have decreased by over 6% recently, largely due to advancements in treatment methods that improve survival rates.
  • New drugs targeting molecular changes in NSCLC and immune-modulating treatments have shown promise in effectively attacking cancer cells.
  • The FDA emphasized the need for a comprehensive and efficient approach to identify suitable patients for new therapies, leading to the development of the Lung Cancer Master Protocol to streamline clinical research for these treatments.

Purpose: Lung Cancer Master Protocol (Lung-MAP), a public-private partnership, established infrastructure for conducting a biomarker-driven master protocol in molecularly targeted therapies. We compared characteristics of patients enrolled in Lung-MAP with those of patients in advanced non-small-cell lung cancer (NSCLC) trials to examine if master protocols improve trial access.

Methods: We examined patients enrolled in Lung-MAP (2014-2020) according to sociodemographic characteristics.

Background: An important issue for patients with cancer treated with novel therapeutics is how they weigh the effects of treatment on survival and quality of life (QOL). We compared QOL in patients enrolled to SWOG S1400I, a substudy of the LungMAP biomarker-driven master protocol.

Methods: SWOG S1400I was a randomized phase III trial comparing nivolumab plus ipilimumab vs nivolumab for treatment of immunotherapy-naïve disease in advanced squamous cell lung cancer.

Background: The COVID-19 pandemic remains a significant global threat. However, despite urgent need, there remains uncertainty surrounding best practices for pharmaceutical interventions to treat COVID-19. In particular, conflicting evidence has emerged surrounding the use of hydroxychloroquine and azithromycin, alone or in combination, for COVID-19.

Background: The Lung Cancer Master Protocol (Lung-MAP; S1400) is a completed biomarker-driven master protocol designed to address an unmet need for better therapies for squamous non-small-cell lung cancer. Lung-MAP (S1400) was created to establish an infrastructure for biomarker screening and rapid regulatory intent evaluation of targeted therapies and was the first biomarker-driven master protocol initiated with the US National Cancer Institute (NCI).

Methods: Lung-MAP (S1400) was done within the National Clinical Trials Network of the NCI using a public-private partnership.

Background: Diagnostic tests, including US Food and Drug Administration (FDA)-approved tests and laboratory-developed tests, are frequently used to guide care for patients with cancer, and, recently, have been the subject of several policy discussions and insurance coverage determinations. As the use of diagnostic testing has evolved, stakeholders have raised questions about the lack of standardized test performance metrics and the risk this poses to patients.

Objectives: To describe the use of diagnostic testing for patients with advanced non-small-cell lung cancer (NSCLC), to analyze the utilization of FDA-approved versus laboratory-developed diagnostic tests, and to evaluate the impact of existing regulatory and coverage frameworks on diagnostic test ordering and physician treatment decision-making for patients with advanced NSCLC.

The traditional regulatory drug approval paradigm comprising discrete phases of clinical testing that culminate in a large randomized superiority trial has historically been predominant in oncology. However, this approach has evolved in the current era of drug development, with multiple other development pathways now being utilized. Indeed, treatment approaches designed on the basis of an improved understanding of cancer biology have led to unprecedented responses in early phase trials, sometimes resulting in drug approvals in the absence of large-scale trials.

Recent scientific progress is, in some cases, leading to transformative new medicines for diseases that previously had marginal or even no treatment options. This offers great promise for people affected by these diseases, but it has also placed stress on the health care system in terms of the growing cost associated with some new interventions. Effort has been taken to create tools to help patients and health care providers assess the value of new medical innovations.

The Lung Master Protocol (Lung-MAP, S1400) is a groundbreaking clinical trial designed to advance the efficient development of targeted therapies for squamous cell carcinoma (SCC) of the lung. There are no approved targeted therapies specific to advanced lung SCC, although The Cancer Genome Atlas project and similar studies have detected a significant number of somatic gene mutations/amplifications in lung SCC, some of which are targetable by investigational agents. However, the frequency of these changes is low (5%-20%), making recruitment and study conduct challenging in the traditional clinical trial setting.

As diagnostic tests become increasingly important for optimizing the use of drugs to treat cancers, the co-development of a targeted therapy and its companion diagnostic test is becoming more prevalent and necessary. In July 2011, the US Food and Drug Administration released a draft guidance that gave the agency's formal definition of companion diagnostics and introduced a drug-diagnostic co-development process for gaining regulatory approval. Here, we identify areas of drug-diagnostic co-development that were either not covered by the guidance or that would benefit from increased granularity, including how to determine when clinical studies should be limited to biomarker-positive patients, defining the diagnostically selected patient population in which to use a companion diagnostic, and defining and clinically validating a biomarker signature for assays that use more than one biomarker.

In July 2012, Congress passed the Food and Drug Administration Safety and Innovation Act (FDASIA). The Advancing Breakthrough Therapies for Patients Act was incorporated into a Title of FDASIA to expedite clinical development of new, potential "breakthrough" drugs or treatments that show dramatic responses in early-phase studies. Using this regulatory pathway, once a promising new drug candidate is designated as a "Breakthrough Therapy", the U.

This study explores the historic use of different endpoints to support regular and accelerated approval of cancer drugs between 2002 and 2012. In the past 10 years, two thirds of oncology regular approvals were based on endpoints other than overall survival. More than three quarters of accelerated approvals were based on response rates.

The US Food and Drug Administration is often criticized as inefficient compared to its European counterpart, the European Medicines Agency. This criticism is especially common in the field of oncology, where severely ill patients have few therapeutic options. We conducted a direct drug-to-drug comparison of the two regulatory agencies' approvals of new oncology drugs.
