Shield reports top-line results from pivotal Phase III study of Feraccru® (Ferric Maltol) in the treatment of IDA in patients with CKD

 

 

  • Primary efficacy endpoint not achieved

  • Tolerability profile of Feraccru reconfirmed

  • A review of the full dataset will be conducted to better understand the result

  • Feraccru remains commercially available for IBD patients with IDA through Shield and its commercial partners in Europe and other ongoing clinical studies will continue

London, UK, 5 February 2018: Shield Therapeutics plc (LSE:STX), a commercial stage, pharmaceutical company delivering innovative specialty pharmaceuticals to address patients’ unmet medical needs, with an initial focus on addressing anaemia associated with renal and gastrointestinal disorders, today announces top-line results from its AEGIS-CKD pivotal Phase III study of Feraccru.  Feraccru is a novel oral ferric iron therapy that has been approved and marketed in Europe since 2016 for the treatment of iron deficiency anemia (IDA), initially in patients with inflammatory bowel disease (IBD).

 

The Feraccru AEGIS-CKD study is a pivotal Phase III trial with a primary endpoint evaluating haemoglobin response to Feraccru (ferric maltol, 30mg twice daily) compared to placebo in the treatment of IDA in patients with chronic kidney disease (CKD).  Top-line data is based on the 16-week primary endpoint, with 168 subjects enrolled in 30 renal centres across the US. 

 

Initial clinical trial results:

Feraccru failed to meet the study’s primary endpoint of demonstrating a statistical difference in change of haemoglobin from baseline compared to placebo at 16 weeks (0.45 v 0.15 g/dL, p=0.1686). 

 

The response at 8 weeks demonstrated separation of the treatment arms (0.53 v 0.0 g/dL), which was not sustained to week 16. 

 

Patient drop-out rate was low over 16 weeks and similar in both arms - 10 (9%) in the Feraccru arm v 7 (12.5%) placebo, reconfirming the strong tolerability profile of Feraccru. 

“We are surprised and disappointed by these top-line findings. Feraccru has previously demonstrated positive efficacy and safety in IBD patients, which led to it being approved in Europe where it continues to gain commercial traction. We now await the full dataset in order to fully understand the study’s outcome and define the next steps in our strategy. Concurrently, we will focus on interacting with EMA on the label expansion application, on concluding the AEGIS-H2H study as expeditiously as possible and on taking actions to extend the current cash runway beyond the end of Q2 2018.”

Other Feraccru pipeline events:

 

Feraccru AEGIS-H2H non-inferiority EU Phase 3b study

The AEGIS-H2H Phase 3b study is designed as a non-inferiority trial comparing the efficacy and safety of Feraccru to the market-leading latest generation form of IV iron (Ferinject/Injectafer, ferric carboxymaltose).  Primary endpoint data from the AEGIS-H2H study is expected to be available in the second half of 2018.  

 

Feraccru in Europe – possible extension of commercial label

In September 2017, Shield submitted an application to the European Medicines Agency, to broaden the existing commercial label for Feraccru to include the treatment of all patients with IDA, which has the potential to significantly expand the market opportunity for Feraccru in Europe.  We continue to expect a final decision from the EMA on this application during the first half of 2018.

 

Strategy and next steps

Shield will continue to analyse the preliminary data findings from the AEGIS-CKD pivotal Phase III study and will conduct a review of the study's full dataset as soon as it is available, to understand the detailed results and assess whether any other confounding factors affected the outcome.  In parallel, Feraccru will continue to be available commercially through Shield and our European partners for IBD patients with IDA.  The Group will seek to provide a further update when it announces its financial results for the year ended 31 December 2017.

About Feraccru®

Feraccru is a novel, stable, non-salt, oral formulation of ferric iron, which has a differentiated mechanism of action compared to salt-based oral iron therapies. When salt-based oral iron therapies are ingested, the iron must dissociate from the salt in the GI tract to allow the iron to be absorbed and treat the IDA.  This free iron readily chelates to form insoluble clumps and produces damaging free radicals that together cause a range of mild-to-severe GI adverse events, including nausea, bloating and constipation, leading to poor tolerability, reduced patient compliance and ultimately treatment failure.  In addition, many patients with IDA are concurrently treated with medicines that raise the pH in the gut which further reduces the effect of salt-based oral iron therapies as they require highly acidic conditions to be absorbed. Feraccru is not an iron salt, and iron can be absorbed from the ferric maltol molecule, as a result, it does not routinely cause the same treatment-limiting intolerance issues. Feraccru has been shown in clinical trials to be well-tolerated by patients even when they had previously failed treatment with salt-based oral iron therapies, which should lead to increased patient compliance and better patient outcomes.

 

Currently, the only treatment option for IDA patients who cannot tolerate salt-based oral iron therapies, is IV iron therapy. IV iron therapies quickly increase iron stores via direct administration of very large doses of iron, causing an increase in Hb levels that is physiologically controlled and occurs over a period of weeks, as is the case with Feraccru.  IV iron therapies, however, are invasive, costly, inconvenient and complex to administer, and also come with potentially life-threatening, spontaneous hypersensitivity reactions.
