Zykadia (ceritinib)

We report a 19-year-old male with ALK-rearranged, radioiodine-refractory PDTC who started systemic therapy with ceritinib, achieving a complete metabolic response. Treatment with the third-generation ALK inhibitor led to a deep and durable complete metabolic response, sustained for more than four years, including persistence of remission after treatment discontinuation, with minimal toxicity. This case highlights the potential role of sequential ALK inhibition to overcome acquired resistance in ALK-rearranged TC and underscores the importance of comprehensive molecular profiling to guide personalized treatment strategies in rare aggressive thyroid cancers.

Our findings reveal that ceritinib disrupts mitochondrial dynamics via the MCU/calpain/Drp1 axis. This study identifies a previously unreported mechanism for ceritinib in thyroid carcinoma, suggesting a novel therapeutic strategy.

Treatment of cancer patients with selective ALK inhibitors, such as Ceritinib, causes dysgeusia. Mice receiving Ceritinib had a dramatic reduction in taste bud volume and innervation, and a significant portion of PHOX2B+ neurons died, demonstrating that ALK is critical for development and maintenance of oral sensory neurons.

This study sought primarily to characterize the inhibition effects of four well-known ALK inhibitors, crizotinib, ceritinib, alectinib, and brigatinib, on human UDP-glucuronosyltransferases (UGTs) in vitro and to assess their potential DDI risks in vivo. In vitro-in vivo extrapolation (IVIVE) suggested that all four ALK inhibitors have potential for DDIs due to their inhibitory effects on UGTs. Among them, the DDI risks of alectinib and brigatinib were much higher than the FDA standard, which may have an impact on the safety of clinical drug use.

Although allosteric GLS inhibitors such as BPTES (Bis-2-(5-phenylacetamido-1,3,4-thiadiazol-2-yl)ethyl sulfide) and later-generation analogs such as CB-839 (Telaglenastat) have pharmacologically validated this target, their clinical utility has been constrained by suboptimal drug-like properties, including poor solubility and bioavailability...This biochemical potency translated to a functional effect in a cellular model of glutamine dependence, as evidenced by a significant depletion of intracellular glutamate pools in LDK378-resistant (LR) cells. Furthermore, TRG-192 demonstrated a favorable preclinical safety profile in initial toxicological assessments. Collectively, these data-encompassing potent target engagement, functional on-target activity, and preliminary safety-provide a compelling rationale for the advancement of TRG-192 into in vivo efficacy studies.

After 3 months, targeted lesions regressed significantly, and progression-free survival exceeded 24 months with ongoing response. This demonstrates efficacy of the ALK inhibitor ceritinib in ALK-rearranged SMARCA4-dNSCLC and underscores the clinical value of genomic-guided therapy.

Among patients who received next-generation ALK TKIs as first-line therapy, continuation of next-generation ALK TKI with PT/Pem led to longer PFS and OS than PT/Pem alone, with no unanticipated toxicities. The modest efficacy of PT/Pem-based regimens overall underscores the need for more effective therapies for TKI-refractory ALK+ NSCLC.

In contrast, permanent discontinuation was associated with higher weight/BSA in brigatinib/ceritinib/crizotinib-treated patients. Higher weight and larger BSA at the start of ALK TKI treatment were associated with higher likelihood of toxicity, leading to more DRs and TIs-particularly in males and patients receiving alectinib and lorlatinib. However, weight and BSA were not associated with treatment outcomes.
