ABSTRACT
The US Food and Drug Administration (FDA) approval of lifileucel, for advanced melanoma, represents the first cellular therapy to reach the clinic for solid cancers. Here, we summarise this landmark approval, consider the associated regulatory pathway, and evaluate the challenges that remain to ensure effective implementation of this advanced 'living' therapy.

Immune checkpoint inhibitors (ICIs) have transformed cancer care. Recently, atezolizumab gained its first global approval in a subcutaneous (SC) formulation by the UK medicines regulator, being notable as the first time an FDA- and/or European Medicines Agency (EMA)-approved ICI has been licensed via this administration route. Here, we discuss this approval, other SC ICIs in development, and the benefits and challenges of this administration route, including potential implications for patient care.

INTRODUCTION: To evaluate how often men with metastatic prostate cancer (mPC) receive standard of care treatment with androgen deprivation therapy (ADT). METHODS: Men aged ≥20 years with newly diagnosed mPC (stage IV) between 2010 and 2018 were identified using California Cancer Registry data. Receipt of hormonal therapy as initial cancer treatment was examined by patient/tumor characteristics at time of diagnosis. Chi-square tests and logistic regression, adjusted for covariates, were performed to assess association between receipt of hormonal therapy and patient/tumor characteristics. RESULTS: We identified 13,680 men with newly diagnosed mPC, of which 3637 had local metastasis (N1) only while 9596 had distant metastasis (M1) with or without N1 disease. 21.8 % (n = 2980) of men did not receive ADT. The highest rate of receiving ADT was among men between ages 75-84 (81.6%) and the lowest rate was in men over 85 (76.0%). Asian men had the largest proportion receiving ADT (n = 962, 81.5%) with remaining subgroups having similar proportion of men receiving ADT (76.8% to 77.2%). Once adjusted for covariates, regression results showed men with a higher Gleason score (8-10) were more likely to receive ADT (OR 2.04, 1.82-2.27, p = < 0.001) as well as men with distant sites of metastatic disease (OR 4.02, 3.62-4.46, p = < 0.001). Men residing in neighborhoods with the lowest socioeconomic status were least likely to receive ADT (OR 0.79, 0.68-0.93, p = 0.0032). No differences in receipt of ADT were observed by race/ethnicity. DISCUSSION: Despite significant advancements in the treatment of mPC in recent years, over one-fifth of patients did not receive ADT, which is the backbone for all new systemic therapies. This dataset might help address some of the prostate cancer care disparities in California.
ABSTRACT
Cancer testis antigen gene 1B (CTAG1B) and its associated gene product; New York oesophageal squamous carcinoma 1 (NY-ESO-1), represent a unique and promising target for cancer immunotherapy. As a member of the cancer testis antigen family (CTA), the protein's restricted expression pattern and ability to elicit spontaneous humoural and cellular immune responses has resulted in a plethora of novel modalities and approaches attempting to harness its immunotherapeutic anti-cancer potential. Here, we discuss the structure and function of CTAG1B/NY-ESO-1 in both health and disease, immunohistochemical detection, as well as the most promising advances in the development of associated anti-cancer therapies. From cancer vaccines to engineered cellular therapy approaches, a multitude of immunotherapies targeting CTA's are coming to the forefront of oncology. Although the efficacy of such approaches have yet to provide convincing evidence of durable response, early phase clinical trial data has resulted in some exciting findings which will have significant potential to act as a platform for future practice changing technologies.

The departure of the UK from the European Union (EU) and affiliated European regulatory bodies, including the European Medicines Agency, on Dec 31, 2020, has resulted in the Medicines and Healthcare products Regulatory Agency becoming an independent national regulator. This change has required a fundamental transformation of the UK drug regulatory landscape, creating both opportunities and challenges for future development of oncology drugs. New UK pharmaceutical policies have sought to make the UK an attractive market for drug development and regulatory review, by offering expedited review pathways coupled to strong collaborative relations with other leading international medicines regulators, outside of Europe. Oncology is a key global therapy area for both drug development and regulatory approval, and the UK Government has been keen to show regulatory innovation and international collaboration through approval of new cancer medicines. In this Policy Review, we examine the new UK regulatory frameworks, policies, and global collaborations affecting new oncology drug approvals after departure from the EU. We explore some of the challenges that might lie ahead as the UK creates new and independent regulatory review and approval processes for the next generation of cancer medicines.

Concerns have been raised that regulatory programs to accelerate approval of cancer drugs in cancer may increase uncertainty about benefits and harms for survival and quality of life (QoL). We analyzed all pivotal clinical trials and all non-pivotal randomized controlled trials (RCTs) for all cancer drugs approved for the first time by the FDA between 2000 and 2020. We report regulatory and trial characteristics. Effects on overall survival (OS), progression-free survival and tumor response were summarized in meta-analyses. Effects on QoL were qualitatively summarized. Between 2000 and 2020, the FDA approved 145 novel cancer drugs for 156 indications based on 190 clinical trials. Half of indications (49%) were approved without RCT evidence; 82% had a single clinical trial only. OS was primary endpoint in 14% of trials and QoL data were available from 25%. The median OS benefit was 2.55 months (IQR, 1.33-4.28) with a mean hazard ratio for OS of 0.75 (95%CI, 0.72-0.79, I2 = 42). Improvement for QoL was reported for 7 (4%) of 156 indications. Over time, priority review was used increasingly and the mean number of trials per indication decreased from 1.45 to 1.12. More trials reported results on QoL (19% in 2000-2005; 41% in 2016-2020). For 21 years, novel cancer drugs have typically been approved based on one single, often uncontrolled, clinical trial, measuring surrogate endpoints. This leaves cancer patients without solid evidence that novel drugs improve their survival or QoL and there is no indication towards improvement.

In our 2020 consensus paper, we devised ten recommendations for conducting Complex Innovative Design (CID) trials to evaluate cancer drugs. Within weeks of its publication, the UK was hit by the first wave of the SARS-CoV-2 pandemic. Large CID trials were prioritised to compare the efficacy of new and repurposed COVID-19 treatments and inform regulatory decisions. The unusual circumstances of the pandemic meant studies such as RECOVERY were opened almost immediately and recruited record numbers of participants. However, trial teams were required to make concessions and adaptations to these studies to ensure recruitment was rapid and broad. As these are relevant to cancer trials that enrol patients with similar risk factors, we have added three new recommendations to our original ten: employing pragmatism such as using focused information sheets and collection of only the most relevant data; minimising negative environmental impacts with paperless systems; and using direct-to-patient communication methods to improve uptake. These recommendations can be applied to all oncology CID trials to improve their inclusivity, uptake and efficiency. Above all, the success of CID studies during the COVID-19 pandemic underscores their efficacy as tools for rapid treatment evaluation.
