OBJECTIVES: In 2021, ACE introduced a company-led submission (CLS) process in oncology, enabling subsidy decisions to be made close to regulatory approval. Non-oncology drugs continue to undergo the physician-led pathway, although some are selected for the CLS process.
This research aims to evaluate ACE’s decision-making factors and subsidy outcomes across a range of HTA appraisals (covering cancer/non-cancer, rare diseases, vaccines and gene therapies).
METHODS: ACE appraisals published between January 2024-April 2026 were identified. Indication reviews, withdrawn appraisals and documents not reporting committee discussion were excluded. Included appraisals were reviewed for decision-making factors (clinical need, clinical value, economic value, budget impact), and subsidy outcomes.
RESULTS: 54 HTA appraisals evaluated 77 regimens (69 drugs/5 gene therapies/3 vaccines); over half were cancer (31; all CLS) and rare disease (15) regimens. 29/77 regimens were recommended for subsidy-listing (15 on first assessment, including 5 for rare diseases; 14 more upon pricing revision, including 1 for rare disease). Fewer cancer vs non-cancer regimens were recommended on first assessment (1 vs 14; 10 vs 4 more upon pricing revision). Among 16 regimens considered cost-effective, 3 had acceptable ICERs of S$15,000-45,000 per QALY, while ICERs were not reported for the remaining regimens.
Amongst the 48 regimens not recommended, 4 were judged to have low clinical need for the regimen, 21 were deemed to have uncertain clinical evidence (commonly due to data immaturity), none were cost-effective, and all had uncertain/unreasonably high budget impact. Nonetheless, uncertain clinical evidence did not preclude subsidy-listing (2 regimens with uncertain clinical evidence received subsidy recommendation); none of the regimens with low clinical need, unreasonably high budget impact or those that were not cost-effective were recommended for subsidy listing on first application.
CONCLUSIONS: Singapore HTA subsidy decisions are driven by clinical need, clinical- and cost-effectiveness, and budget certainty. Pricing resubmissions improved recommendation outcomes, particularly for cancer regimens.
