2011–004761-33, was designed after extensive study of the published CF RCTs [14]. We use cookies to improve your website experience. The frequent prophylactic infusions of recombinant FVIII (rFVIII) or recombinant FIX (rFIX) begin from the first one or two years of life, often continuing throughout adulthood. The risk of bias in the evaluation of results for all RCTs was assessed as low. Browse over 50,000 other reports on our store. There was no deviation from the researchers’ pre-specified intentions for planned outcome measurements and analyses [11]. These results were published in the New England Journal of Medicine in January 2020. 2004–002508-13, the mechanism of randomisation was not described and changes in the protocol from the original version were not specified. 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). The data from secondary efficacy endpoints, and progression-free survival were adjudicated by blinded peer review [6]. The main reasons for premature withdrawal were the sponsor’s decision to discontinue treatment with the CT drug, withdrawal initiated by the investigator, and IC withdrawn by the patient [6]. By closing this message, you are consenting to our use of cookies. The method has been criticized because, depending on last observed data, it assumes no disease progression or improvement after dropout, which leads to biased results [13]. The study was an event-driven trial and all clinical events were reviewed by both a non-blinded Data Monitoring Committee and an independent blinded Clinical Endpoints Committee. The approval of valoctocogene roxaparvovec will greatly contribute to BioMarin’s profits and further growth. Risk of bias in this domain depends on appropriateness of the method used for outcome measuring, the outcome assessor and whether the outcome assessor is blinded to intervention assignment [4]. Another limitation of this review is that only RCTs were considered for analysis. However, the primary efficacy parameter was assessed by PWT, which did not involve outcome assessor judgement. To date, the FDA has approved four gene therapy products, which insert new genetic material into a patient’s cells. Phase 1 & 2. 2004–002508-13, all eligible reported results for the outcome corresponded to all intended outcome measurements [9,10]. Study nos. Visit GlobalData Store, Enhancing Oral Formulations of Large and Polar APIs, Rubber Parts for Primary Packaging and Medical Devices Solutions, Laboratory Testing and Project Management for Clinical Trials, 14 January 2020 (Last Updated January 14th, 2020 16:13). A successful gene therapy delivers a gene into the exact cells of our body that require this gene. Not for Distribution. If approved, BioMarin’s candidate will be the first gene therapy product to ever become marketed in the entire haemophilia market, including both haemophilia A and B. Haemophilia A and B are congenital, genetic X-linked deficiencies in the blood clotting factor VIII (FVIII) and clotting factor IX (FIX), respectively. 2012–001700-37) was detailed information for blinding of all participants in the trial provided. 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. Gene Therapy Market Slumps by -13.6% The global market for Gene Therapy is expected to decline by -13.6% in the year 2020 … Given the great potential of gene therapy in the haemophilia market, more companies are developing gene therapies for both indications, A and B. There was no specific data provided on trial participants masking. (2020). Pfizer and UniQure are testing their drugs, fidanacogene elaparvovec and AMT-061 respectively, in haemophilia B, while Spark is chasing after BioMarin in haemophilia A with its pipeline therapy SPK-8011. 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. Dublin, Nov. 27, 2020 (GLOBE NEWSWIRE) -- The "Gene Therapy - Global Market Trajectory & Analytics" report has been added to ResearchAndMarkets.com's offering. All three diseases are more common than other rare diseases, which allowed the recruitment of a sufficient number of patients [19–21]. 2004–002508-13 were similar, which suggest low risk of bias. It also impedes the conduct of more RCTs with GTs. The use of a statistical tool would be beneficial for drawing empirical evidence for how the presence of bias in different domains influences the estimation of the intervention effect. Pre-Clinical. The number of patients with missing test was similar across three treatment groups and placebo, and the reasons for not performing it were described in the published results.

Currently, a program that is still ongoing started developing COS for CTs in renal cancer (http://www.comet-initiative.org/studies/details/1406). Based on the reviewed data, the overall risk of bias in study nos. In three of the reviewed RCTs, blinding was described only with the broad term ‘double blind’. 2006–001246-13 did not provide specific information on the masking of participants. Registered in England & Wales No. Clinical examination results, including pulmonary function, gas transfer markers, and systemic inflammation indicators were examined in a masked manner by the DMEC [14]. To ensure better consistency in reported outcomes in trials in the same clinical area, core outcome sets (COS) have been developed. 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. Now, in 2020, the FDA expects to see a doubling of new gene therapy applications every year. In three CTs, the risk in all bias domains was rated as low and only one CT identified a moderate risk of bias due to lack of information regarding the randomization process. 2004–002508-13 was estimated with ‘some concerns’.

Because of the missing clear justification for using LOCF [4], the risk of bias due to missing outcome data was assessed as with ‘some concerns’. In study no. This domain focuses mainly on differential errors related to intervention assignment. The COS for peripheral arterial disease was developed in 2018 [18]. This review indicates that most CTs conducted with GTMPs have a very small number of patients, are single-arm trials, and are conducted without comparative therapy or placebo.
