Apr 20 · In its latest annual report, Vifor announces that following positive topline data for the avacopan pivotal PIII ADVOCATE trial announced in 2019, filing in Europe is expected in 2020 [9].

Mar 20 · Following on from advice received from the company, NICE has decided to suspend this appraisal from its current work programme [7].

Mar 20 · In its latest annual report, ChemoCentryx states that in the US, it is currently preparing an NDA for avacopan, which it plans to file with the FDA in mid-2020. The company will also support its international commercialisation partner Vifor and its Japanese sublicensee Kissei Pharmaceutical, Co., Ltd. in their regulatory approval applications. Vifor will commercialise avacopan in Europe [8]

Nov 19 · Company announced plans to make regulatory submissions for full marketing approval to both the EMA and FDA in 2020.[7]

Jan 19 · In their announcement of the EMA application withdrawal, Chemocentryx comment that they expect topline data from the ADVOCATE trial in Q4 2019 and expect to re-apply to both EMA and FDA in 2020 based on this data. With PRIME status, EU approval could take as little as 8 months from filing if there are no delays. [6]

Jan 19 · EMA filing withdrawn. The filing was for conditional authorisation, and at the time of withdrawal the CHMP was of the provisional opinion that the data provided by the company to that point were insufficient to show effectiveness. There were also concerns over the limited safety data and over the choice of starting materials used in manufacture. The Committee was therefore of the opinion that the company had not provided enough data to support the application. In reply, the company has stated that it intends to focus on future submission of a full marketing authorisation: this will be based on the results of the ongoing ADVOCATE study, which is larger and has a longer treatment duration [5].

Feb 21 · In the PIII ADVOCATE RCT (n=331 on cyclophosphamide or rituximab), avacopan, a C5a receptor inhibitor, was non-inferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52 [12].

Nov 19: Pivotal PIII ADVOCATE trial met both primary endpoints; with remission rates (assessed by BVAS) at week 26 reaching 72.3% with avacopan compared vs. 70.1% with glucocorticoid standard-of-care (control gp). Sustained remission at 52 weeks was seen in 65.7% in the avacopan gp vs. c54.9% in the control group.[7]

Dec 16: PIII ADVOCATE trial to evaluate the safety and efficacy of avacopan in 300 US patients with ANCA-associated vasculitis or AAV treated concomitantly with rituximab or cyclophosphamide/azathioprine starts (NCT02994927). The primary endpoints will be remission and sustained remission, assessed at 26 and 52 weeks, respectively, using Birmingham Vasculitis Activity Score.
