Drug development in the name of social justice?

This important study is one I want to make a note of on here for future reference.  

It addresses a range of issues I believe are among those most critical not only for communicating the importance of translational gerontology, but for how we conceive of the demands of social justice more broadly.  

The abstract:

The central premise of this article is that a portion of the established relationships between social determinants of health and racial/ethnic disparities in cancer morbidity and mortality are mediated through differences in rates of biological aging processes. We further posit that using knowledge about aging could enable discovery and testing of new mechanism-based pharmaceutical and behavioral interventions ("gerotherapeutics") to differentially improve the health of minoritized cancer survivors and reduce cancer disparities. These hypotheses are based on evidence that lifelong differences in adverse social determinants of health contribute to disparities in rates of biological aging ("social determinants of aging"), with minoritized groups having accelerated aging (ie, a steeper slope or trajectory of biological aging over time relative to chronological age) more often than non-minoritized groups. Acceleration of biological aging can increase the risk, age of onset, aggressivity and/or stage of many adult cancers. There are also documented negative feedback loops whereby the cellular damage caused by cancer and its therapies act as drivers of additional biological aging. Together, these dynamic intersectional forces can contribute to differences in cancer outcomes between minoritized vs non-minoritized survivor populations. We highlight key targetable biological aging mechanisms with potential applications to reducing cancer disparities and discuss methodological considerations for pre-clinical and clinical testing of the impact of gerotherapeutics on cancer outcomes in minoritized populations. Ultimately, the promise of reducing cancer disparities will require broad societal policy changes that address the structural causes of accelerated biological aging and ensure equitable access to all new cancer control paradigms.
