Mereo BioPharma

Entering an important 12 month period

Update | 19 September 2019

Share this note

Mereo BioPharma made significant progress strategically during H119 with the completion of the merger with OncoMed, and now is entering a critical 12-month period. Full 12-month data from the Phase II study in osteogenesis imperfecta (OI) with setrusumab (BPS-804) is due in Q419; promising 6-month data in the open-label arm has already been reported. Phase II data with its second rare-disease asset, alvelestat (MPH-966), in α-1 antitrypsin deficiency (AATD) is expected in mid-2020. The company will also be looking to partner its non-core assets to strengthen its balance sheet, with negotiations on acumapimod (BCT-197) for acute COPD most advanced. We maintain our valuation of Mereo at 506p/share or $25.59/ADS.

  • Full Phase II setrusumab OI data due in Q419 Six-month data from the open-label arm of the Phase II study in OI with setrusumab, suggest the product could have a competitive profile. The mean improvement at six months in bone mineral density (BMD, assessed using HRpQCT) was 3.2%, a level of improvement that is only seen at best after a year with bisphosphonates, the current standard-of-care. The full 12-month data from all 112 adult patients, with three monthly dosing regimens, will be reported in Q419. A Phase III paediatric study in Canada and Europe is ready to begin, though the final design will use the learnings from the current study.
  • Alvelestat top-line AATD results expected mid-2020 Recruitment to the Phase II study in AATD with alvelestat  (n=165) is progressing as expected, although it took longer than hoped to initiate the trial centres. Mereo now expects top-line data to be published mid-2020. An investigator-led study (ILS) should provide further indication of alvelestat potential in AATD (n=66, data due in H221), and another ILS could expand development of the compound into bronchiolitis obliterans syndrome (BOS), progressive loss of pulmonary function following lung transplantation.
  • Partnering needed to strengthen the balance sheet Mereo has four non-rare disease assets it is looking to partner, two of which it acquired with OncoMed. Negotiations are most advanced with acumapimod for acute COPD, and the outline of a pivotal Phase III study has been agreed with the FDA.  Any proceeds from partnering will be used to support the development of the rare disease products.
  • Current valuation fails to reflect the six clinical assets Our rNPV valuation of Mereo is unchanged at 506p/share or $25.59/ADS (fully diluted), although we have updated our estimates to fully reflect the merger with OncoMed and the H119 results. Its cash position of £36.1m at H119 should enable Mereo to operate to the end of H120, in the absence of a partnering deal or an equity raise.

Exhibit 1: Summary of financials
Source: Company, Trinity Delta; Notes: Our estimates exclude the costs associated with the pivotal Phase III paediatric study with BPS-804, because the timing of the trial is yet to be decided. We include in FY20 long-term debt (other financing cash flow) of £25m, which is indicative of our estimate of the company’s capital requirement; this could be achieved through an equity raise, debt or proceeds from partnering non-rare disease assets.
