Prothena (PRTA) Reports Wider-than-Expected Loss in Q3

RHHBY EXEL PRTA

Prothena Corporation plc (PRTA - Free Report) reported a loss of $1.26 per share in the third quarter of 2016, wider than both the Zacks Consensus Estimate of a loss of $1.23 and the year-ago loss of 73 cents.

Moreover, quarterly revenues came in at $0.3 million, down 25% primarily due to lower contributions from the collaboration agreement with Roche Holding AG (RHHBY - Free Report) . The top line was, however, in line the Zacks Consensus Estimate.

Quarter in Detail

Research and development (R&D) expenses were $26.8 million, up 55.8% year over year primarily due to increased expenses related to pipeline development, product manufacturing, and higher personnel costs.

General and administrative (G&A) expenses were $16.1 million, up a substantial 47.3% year over year mainly due to higher personnel costs.

2016 Outlook

Prothena has revised its 2016 net cash burn projection. The company now expects net cash burn from operating and investing activities in the range of $132–$142 million (previous projection: $118–$128 million).

The company, however, continues to expect to end the year with approximately $376 million in cash, cash equivalents and restricted cash (midpoint).

Pipeline Update

Prothena continues to progress with the candidates in its pipeline. The company is evaluating its lead candidate NEOD001 in the phase III VITAL Amyloidosis study in newly diagnosed treatment-naïve patients with AL amyloidosis and cardiac dysfunction. Patient enrollment in the study is expected to be complete in the second quarter of 2017.

The company is also evaluating the candidate in a phase IIb study, PRONTO, in previously treated patients with AL amyloidosis and persistent cardiac dysfunction. Top-line results from the study are expected in early 2018.

Moreover, Prothena is evaluating PRX002, in collaboration with Roche, for the treatment of Parkinson’s disease and other related synucleinopathies. Top-line data from a phase Ib multiple-ascending dose study are expected this month.

Our Take

The wider-than-expected loss in the third quarter was disappointing. Nevertheless, the company’s efforts on developing its pipeline are encouraging. We expect investor focus to remain on further updates from its late-stage candidate, NEOD001.
