NCT06090318
This is an open-label, single-arm, Phase 1b/2 study designed to evaluate the safety, tolerability, and preliminary efficacy of milademetan in combination with atezolizumab in patients with advanced solid tumors with confirmed homozygous CDKN2A loss and WT TP53 who have progressed on or are refractory to prior PD-1/PD-L1 inhibitor therapy and who, in the opinion of the Investigator, are unlikely to tolerate or derive clinically meaningful benefit from other therapy. This study will determine the recommended dose of milademetan when given in combination with atezolizumab (the combination RP2D) using a dose de-escalation safety assessment cohort (Phase 1b). Following identification of the combination RP2D, the safety profile and preliminary anti-tumor activity of the combination RP2D will be evaluated in a larger population in a dose expansion cohort (Phase 2).
NCT04598516
Intravascular iodinated contrast administration has become crucial to modern medicine. Currently it is estimated that over 250 million injections are given each year worldwide during medical scans and interventions. An acute predefined increase in serum creatinine is considered an indicator of acute kidney injury (AKI). When such an acute increase in serum creatinine occurs within 5 days post-contrast in absence of another aetiology, it is assumed to be iodinated contrast administration induced acute kidney injury. For over 50 years now, acute kidney injury caused by intravascular administration of iodinated contrast material has been considered a leading cause of hospital-acquired renal failure. Contrast has been withheld in fear of kidney injury with misdiagnoses and delayed appropriate patient management as a result. Since 2018, it is now widely accepted that only patients with eGFR \<30 mL/min/1.73m2 are at risk of renal injury after intravascular iodinated contrast material injection. However, no study to date has been able to distinguish acute kidney injury caused by iodinated contrast administration from that for which no causal link is established, and it is unsure a causal relationship exists. There are several studies, in attempts to evaluate the causal relationship between contrast exposure and nephrotoxicity, that found fluctuations in absence of contrast similar to those considered to be contrast-induced acute kidney injury. Similarly, it is unsure whether longer-term negative outcomes are inherent to the population studied or a result of contrast administration. However, most of these studies are observational and retrospective in nature. The issue with retrospective studies is that they often cannot control for confounders and therefore cannot give us causation, only association. On the other hand, prospective randomized controlled trials comparing intravascular iodinated contrast administration to no contrast are unlikely given evident ethical issues. The current prospective observational study proposes to use intra-patient comparisons of peak change in renal function during periods in absence of- and with contrast to elucidate the relationship between renal function and contrast administration in this population.
