The management of myelodysplastic syndrome (MDS) and chronic myelomonocytic leukemia (CMML) is limited and remains an unmet need. Decitabine/cedazuridine (DEC-C, ASTX727) is Canada’s first and only approved oral hypomethylating agent for MDS and CMML. We characterized the real-world use of DEC-C through a Canadian compassionate use program. Demographic and clinical data from 769 patients enrolled in Taiho Pharma Canada’s Patient Support Program were collected and analyzed. These patients represent a collection period from 10 November 2020 to 31 August 2022 with a median age of 76 years. Among 651 patients who started DEC-C, the median treatment duration was 4.2 cycles. The median overall and progression-free survival were 21.6 and 10.7 months, respectively. Among 427 patients who discontinued treatment, the majority (69.5%) stopped due to death (n = 164) or disease progression (n = 133). Multivariable cox regression showed that age, province of residence, blast counts, antibiotic prophylaxis, and number of dose reductions and delays were not significantly associated with overall and progression-free survival. DEC-C is a promising alternative to parenteral hypomethylating agent therapy, and it likely addresses an important unmet need for effective and convenient therapies in this setting.

Background: Gastric cancer mortality remains among the highest of all cancers. Trifluridine/tipiracil (FTD/TPI) represents Canada’s first standard-of-care, third-line, systemic therapy for metastatic gastric/gastroesophageal cancer. We characterized real-world treatment patterns in patients enrolled to receive FTD/TPI through Taiho Pharma Canada’s Patient Support Program. Methods: Demographic and clinical information were collected from November 2019 to November 2021 for adult patients with refractory metastatic gastric/gastroesophageal cancer throughout Canada. We examined all variables using descriptive statistics and performed survival and association analyses. Results: 162 patients enrolled to receive FTD/TPI with a median age of 65 years, 12 of whom had HER2 positive disease. Among 123 patients who started FTD/TPI, median follow-up was 3.1 months and median progression-free survival (PFS) was 3.5 months (95% CI 3.2–4.0). Among 121 patients who discontinued FTD/TPI, median treatment duration was 2.39 cycles (IQR 1.14–3.86). A total of 52% discontinued treatment due to disease progression, and 27% had a dose reduction or delay. On multivariable logistic regression, prior FOLFIRI was a statistically significant predictor of treatment modification. Conclusions: Through the Patient Support Program, FTD/TPI is an actively utilized treatment option in heavily pretreated metastatic gastric/gastroesophageal cancer, despite its recent introduction. With longer-than-expected treatment duration and PFS, FTD/TPI likely addresses an important unmet need for effective and tolerable therapies in this setting.
