This significantly limits the conclusions that can be drawn about the methodology and design of CTs with GTMPs due to the small number of identified RCTs. According to the Global Gene Therapy Clinical Trials Registry [23], 2686 CTs were conducted in a shorter time period than the current systematic review (1 January 1995–31 December 2018), which is a far greater number than that found in the current search. In this domain, RCTs were reviewed for risk of bias that arose because of selection of the reported results [4]. 5 Howick Place | London | SW1P 1WG. If you continue to use this site we will assume that you are happy with it. Spark Therapeutics, Pfizer, and UniQure all have gene therapy products in Phase III development. US KOLs interviewed by GlobalData consider the time to market a deciding factor for the success of a product and agree that a first-in-market drug can achieve higher market shares than its contenders. Only in one of the reviewed RCTs (study no. ... be in Phase 3 Studies by 2H 2020 Gene Therapy ( GTx) Phase 3. 8, No. GlobalData’s primary research revealed that patients with severe forms of the disease are increasingly treated on a prophylactic basis rather than on-demand after bleeds, since this significantly reduces the occurrence of bleeding episodes. Phase 1 & 2. Selection of reliable and well-defined objective endpoints which demonstrate clinical benefits and design plans for managing missing outcomes will minimize the bias in outcome analysis. In clinical areas where potential GTs may offer treatment options, academia should consider the development of COS to evaluate efficacy and safety similar to the coreHEM project (http://www.comet-initiative.org/studies/details/997). 2012–001700-37) was detailed information for blinding of all participants in the trial provided. To date, the FDA has approved four gene therapy products, which insert new genetic material into a patient’s cells. Journal of Market Access & Health Policy: Vol. 2004–002508-13, the methods of outcome measurement were very specific and the same measurement methods and thresholds in both the intervention and placebo groups were used at comparable time points. 2004–002508-13 were similar, which suggest low risk of bias. Additionally, the gene therapy has received Orphan Drug Designation from both regulatory authorities. The proportion and reasons for missing outcome data in the experimental and placebo intervention groups in study no. Scott Gottlieb, the former FDA commissioner, predicted that by the year 2025, the US will be approving between 10 and 20 different gene therapies every year. Now, in 2020, the FDA expects to see a doubling of new gene therapy applications every year. Property of Pfizer. The clinical outcomes in study no. Currently, a program that is still ongoing started developing COS for CTs in renal cancer (http://www.comet-initiative.org/studies/details/1406). Gene therapies are expected to capture 7.5% of the market in the US and 18.6% of the market in the 5EU by 2028. In all reviewed RCTs, in both intervention and placebo groups the size of the number of participants with missing outcome data and reasons for this were similar. The reasons for missing data between the two intervention groups were similar, well documented, and not related to the CT outcome itself [7]. The relevant data were extracted once the database was locked and the researchers were unblinded [14]. The estimated primary completion date for the GENEr8-1 trial is December 2022. Оf the 9 RCTs, 5 (56%) were for studying GTs for rare diseases (cystic fibrosis, locally advanced or metastatic renal clear cell adenocarcinoma and LHON).

BioMarin’s recent submissions of an MAA in November 2019 to the EMA and of a biologics license application (BLA) in December 2019 to the FDA were based on results from a Phase I/II study (BioMarin Pharmaceutical, NCT02576795) alongside interim analysis results from the ongoing Phase III GENEr8-1 study (BioMarin Pharmaceutical, NCT03370913). Missing data from the 26-week peak walking time test (PWT), where the percentage change from baseline was used as primary efficacy endpoint, was input to the last-observation-carried-forward method (LOCF). 2006–001246-13 were common for cancer therapy (patient survival and progression-free survival).
