Modeling severe uncontrolled asthma: Transitioning away from health states.

Background: Models developed to date to simulate long-term outcomes of asthma have been criticized for lacking granularity and ignoring disease heterogeneity.

Objective: To propose an alternative approach to modeling asthma and apply it to model long-term outcomes in a population with moderate-to-severe type 2 asthma (patients with raised fractional exhaled nitric oxide or eosinophils) and treated with conventional therapy.

Methods: A discretely integrated condition event (DICE) approach was adopted, simulating individual profiles with asthma over patients' lifetime in terms of exacerbations, asthma-related death, and death unrelated to asthma.

Uncertain about uncertainty in matching-adjusted indirect comparisons? A simulation study to compare methods for variance estimation.

In health technology assessment, matching-adjusted indirect comparison (MAIC) is the most common method for pairwise comparisons that control for imbalances in baseline characteristics across trials. One of the primary challenges in MAIC is the need to properly account for the additional uncertainty introduced by the matching process. Limited evidence and guidance are available on variance estimation in MAICs.

Efficacy of avalglucosidase alfa on forced vital capacity percent predicted in treatment-naïve patients with late-onset Pompe disease: A pooled analysis of clinical trials.

Background: The efficacy of avalglucosidase alfa (AVA) versus alglucosidase alfa (ALG) on forced vital capacity percent predicted (FVCpp) in patients with late-onset Pompe disease (LOPD) has been assessed in the Phase 3 COMET trial (NCT02782741). Due to the rarity of LOPD and thus small sample size in COMET, additional data were analyzed to gain further insights into the efficacy of AVA versus ALG.

Methods: Data from treatment-naive patients with LOPD were pooled from COMET and Phase 1/2 NEO1/NEO-EXT (NCT01898364/NCT02032524) trials for patients treated with AVA, and Phase 3 LOTS trial (NCT00158600) for patients treated with ALG.

Efficacy of Mobocertinib and Amivantamab in Patients With Advanced Non-Small Cell Lung Cancer With EGFR Exon 20 Insertions Previously Treated With Platinum-Based Chemotherapy: An Indirect Treatment Comparison.

Introduction: Exon 20 insertions (ex20ins) mutations of the EGFR gene account for 1% to 2% of all non-small-cell lung cancers (NSCLCs). Targeted therapies have been developed to treat this cancer type but have not been studied in head-to-head trials. Our objective was to use a matching-adjusted indirect comparison (MAIC) to assess the efficacy of mobocertinib and amivantamab in patients with NSCLC EGFR ex20ins mutations who were previously treated with platinum-based chemotherapy.

Regorafenib versus Cabozantinib as a Second-Line Treatment for Advanced Hepatocellular Carcinoma: An Anchored Matching-Adjusted Indirect Comparison of Efficacy and Safety.

Introduction: The tyrosine kinase inhibitors regorafenib and cabozantinib remain the mainstay in second-line treatment of advanced hepatocellular carcinoma (HCC). There is currently no clear evidence of superiority in efficacy or safety to guide choice between the two treatments.

Methods: We conducted an anchored matching-adjusted indirect comparison using individual patient data from the RESORCE trial of regorafenib and published aggregate data from the CELESTIAL trial of cabozantinib.
