Oncology therapy is becoming increasingly more expensive and challenging the affordability sustainability of drug programmes around world. When new drugs are evaluated, health technology assessment organisations rely on clinical trials to inform funding decisions. However, not able assess overall survival generalises evidence in a real-world setting. As result, policy makers have little information whether decisions based ultimately yield outcomes value for money that might be expected.The...

Abstract Background Current treatment of diffuse-large-B-cell lymphoma (DLBCL) includes rituximab, an expensive drug, combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy. Economic models have predicted rituximab plus CHOP (RCHOP) to be a cost-effective alternative alone as first-line DLBCL, but it remains unclear what its real-world costs cost-effectiveness are in routine clinical practice. Methods We performed population-based retrospective cohort...

We assessed the real-world safety effectiveness compared to Herceptin patients with Methods: This was a population-based, retrospective study comparing neoadjuvant/adjuvant cancer from 2016 2021. Treatment started November 2019 June 2021; historical comparator October 2019. Safety outcomes death within 30 days last dose trastuzumab, direct...

Multi-criteria decision analysis (MCDA) is a value assessment tool designed to help support complex decision-making by incorporating multiple factors and perspectives in transparent, structured approach. We developed an MCDA rating tool, consisting of seven criteria evaluating the importance feasibility conducting potential real-world evidence (RWE) studies aimed at addressing uncertainties stemming from initial cancer drug funding recommendations. In collaboration with Canadian Agency for...

Abstract Is it ethical to market complementary and alternative medicines? Complementary medicines (CAM) are medical products services outside the mainstream of practice. But they not just (or supposed medicines) offered provided for prevention treatment illness. They also – things sale in marketplace. Most discussion ethics CAM has focused on bioethical issues having do with therapeutic value, relationship between patients those purveyors CAM. This article aims instead consider from...

Background. Real-world evidence can be a valuable tool when clinical trial data are incomplete or uncertain. Bevacizumab was adopted as first-line therapy for metastatic colorectal cancer (mCRC) based on significant survival improvements in initial trials; however, benefit diminished subsequent analyses. Consequently, there is uncertainty surrounding the cost-effectiveness of bevacizumab achieved practice. Objective. To assess real-world with irinotecan-based chemotherapy versus alone mCRC...

Abstract Background Advanced pancreatic cancer (APC) patients often have substantial symptom burden. In Ontario, routinely complete the Edmonton Symptom Assessment Scale (ESAS), which screens for nine symptoms (scale: 0‐10), in clinics. We explored association between baseline patient‐reported outcomes, via ESAS, and overall survival (OS). Methods with ESAS records prior to receiving publicly funded drugs from November 2008 March 2016 were retrospectively identified Cancer Care Ontario's...

Abstract Background For novel cancer treatments, effectiveness in clinical practice is not always aligned with efficacy results. As such it important to understand a treatment’s real-world effectiveness. We examined population-based comparative of second-line ipilimumab versus non-ipilimumab treatments (chemotherapy or targeted treatments). Methods used cohort melanoma patients receiving systemic treatment for advanced disease since April 2005 from Ontario, Canada. Patients were identified...

Abstract Background There are no randomized control trials (RCTs) comparing gemcitabine and nab-paclitaxel (Gem-Nab) fluorouracil, folinic acid, irinotecan, oxaliplatin (FOLFIRINOX) for advanced pancreatic cancer (APC). Although it is well known that RCT-based efficacy often does not translate to real-world effectiveness, there limited literature investigating comparative cost-effectiveness of Gem-Nab vs FOLFIRINOX APC. We aimed examine the APC in Ontario, Canada. Methods This study compared...

Abstract Background The efficacy‐effectiveness gap between randomized trial and real‐world evidence regarding the clinical benefit of ipilimumab for metastatic melanoma (MM) has been well characterized by previous literature, consistent with initial concerns raised health technology assessment agencies (HTAs). As these differences can significantly impact cost‐effectiveness, it is critical to assess cost‐effectiveness second‐line versus non‐ipilimumab treatments MM. Methods This was a...

Second-line ipilimumab has been publicly funded in Ontario for metastatic melanoma (MM) since September 2012. We examined real-world toxicity of second-line compared to standard treatments prior funding. MM patients who received systemic treatment from April 2005 March 2015 were included. Patients receiving after 2012 considered as cases, and those the funding date included historical controls. Outcomes assessed include treatment-related mortality, any-cause hospital visits,...
