Evaluation of the Relationship of Glasdegib Exposure and Safety End Points in Patients With Refractory Solid Tumors and Hematologic Malignancies.

ABSTRACT: Glasdegib is approved for treating acute myeloid leukemia in elderly patients at 100 mg once daily in combination with low-dose cytarabine. Exposure-efficacy analysis showed that the survival benefit of glasdegib was not glasdegib exposure-dependent. The relationship between glasdegib exposure and adverse event (AE) cluster terms of clinical concern was explored in this analysis. The incidence and severity of dysgeusia, muscle spasms, renal toxicity, and QT interval prolonged was modeled using ordinal logistic regression. AEs were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03). Estimated pharmacokinetic parameters were used to derive glasdegib exposure metrics. Demographic characteristics, disease factors, and other variables of interest as potential moderators of safety signals were evaluated. Clinical trial data from patients who received single-agent glasdegib (N = 70; 5-640 mg once daily); or glasdegib (N = 202, 100-200 mg once daily) with low-dose cytarabine, decitabine, or daunorubicin and cytarabine were analyzed. Glasdegib exposure was statistically significantly associated with the cluster term safety end points dysgeusia, muscle spasms, renal toxicity, and QT interval prolonged. The impact of age on muscle spasms and baseline body weight and creatinine clearance on renal toxicity helped explain the AE grade distribution. At the 100 mg once daily clinical dose, the predicted probabilities of the highest AE grade were 11.3%, 6.7%, 7.7%, and 2.5% for dysgeusia, muscle spasms, renal toxicity, and QT interval prolonged, respectively. Overall, the predicted probability of developing an AE of any severity for these safety end points was low. Therefore, no starting dose adjustments are recommended for glasdegib based on the observed safety profile.

Project description:Hematologic malignancies are a heterogeneous group of diseases with unique illness trajectories, treatment paradigms, and potential for curability, which affect patients' palliative and end-of-life care needs. Patients with hematologic malignancies endure immense physical and psychological symptoms because of both their illness and often intensive treatments that result in significant toxicities and adverse effects. Compared with patients with solid tumors, those with hematologic malignancies also experience high rates of hospitalizations, intensive care unit admissions, and in-hospital deaths and low rates of referral to hospice as well as shorter hospice length of stay. In addition, patients with hematologic malignancies harbor substantial misperceptions about treatment risks and benefits and frequently overestimate their prognosis. Even survivors of hematologic malignancies struggle with late effects, post-treatment complications, and post-traumatic stress symptoms that can significantly diminish their quality of life. Despite these substantial unmet needs, specialty palliative care services are infrequently consulted for the care of patients with hematologic malignancies. Several illness-specific, cultural, and system-based barriers to palliative care integration and optimal end-of-life care exist in this population. However, recent evidence has demonstrated the feasibility, acceptability, and efficacy of integrating palliative care to improve the quality of life and care of patients with hematologic malignancies and their caregivers. More research is needed to develop and test population-specific palliative and supportive care interventions to ensure generalizability and to define a sustainable clinical delivery model. Future work also should focus on identifying moderators and mediators of the effect of integrated palliative care models on patient-reported outcomes and on developing less resource-intensive integrated care models to address the diverse needs of this population.
