Five Prime Therapeutics Reports Third Quarter 2019 Results

November 6, 2019 at 4:05 PM EST

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Nov. 6, 2019-- Five Prime Therapeutics, Inc. (NASDAQ: FPRX), a clinical-stage biotechnology company focused on developing immune modulators and precision therapies for solid tumor cancers, today announced its results for the third quarter and provided an update on the company’s recent activities.

“We have advanced all of our wholly-owned programs according to our plan for 2019,” said William Ringo, Chairman and interim Chief Executive Officer of Five Prime Therapeutics. “As we approach 2020, we have repositioned Five Prime with a focus on prioritizing our pipeline based on upcoming data readouts, while also extending our cash runway, in order to maximize the long-term potential of the company.”

Third Quarter 2019 Business Highlights and Milestones

Clinical Pipeline:

Bemarituzumab (anti-FGFR2b) is a first-in-class isoform-selective antibody with enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) in development as a targeted immunotherapy for tumors that overexpress FGFR2b. Bemarituzumab is being evaluated in combination with mFOLFOX6 in the Phase 3 FIGHT (FGFR2b Inhibition in Gastric and Gastroesophageal Junction Cancer Treatment) trial.

  • The company has enrolled approximately 140 patients with newly diagnosed advanced stage gastric cancer into the FIGHT trial, representing approximately 25% of projected total trial enrollment, and has paused pre-screening of patients for enrollment in the trial.
  • The prevalence of FGFR2b overexpression in this patient population is approximately 30% based on global pre-screening data.
  • The company expects to conduct a planned futility analysis for the FIGHT trial in mid-2020. The purpose of the futility analysis is to ensure the trial is adequately powered to detect an overall survival benefit at full enrollment.

FPA150 (anti-B7-H4) is a first-in-class B7-H4 antibody designed to target tumor cells by enhancing killing of B7-H4 overexpressing tumors through ADCC and by blocking B7-H4 from sending an inhibitory signal to CD8 T cells. B7-H4 is frequently overexpressed in breast, ovarian and endometrial cancers.

  • The company presented a poster at the European Society for Medical Oncology (ESMO) Congress with preliminary FPA150 efficacy results from the monotherapy Phase 1b expansion cohorts at the 20mg/kg dose in patients with breast, ovarian or endometrial cancers that overexpress B7-H4.
  • As of the August 9, 2019 data cut-off date, one patient in the ovarian cohort had a confirmed response; 11 patients had stable disease and remained on therapy. As of the data cut-off date, 31 patients across the ovarian, endometrial and breast cohorts were evaluable for response.
  • The company also presented safety data for four patients in the combination arm of FPA150 with Keytruda® (pembrolizumab) suggesting that FPA150 could be combined at a full dose of 20 mg/kg every three weeks with the standard dose of pembrolizumab.

FPT155 (CD80-Fc) is a first-in-class CD80-Fc fusion protein that uses the binding interactions of soluble CD80 to directly engage CD28 to enhance its co-stimulatory T cell activity without inducing super agonism and to block CTLA-4 from competing for endogenous CD80, allowing CD28 signaling to prevail in T cell activation in the tumor microenvironment.

  • On November 9, the company will present initial safety data from the Phase 1 clinical trial of FPT155 in patients with advanced solid tumors in a poster presentation at the Society for Immunotherapy of Cancer (SITC) 34th Annual Meeting in National Harbor, Maryland.
  • FPT155 data presented at SITC will include initial safety results from the Phase 1a dose escalation portion of the trial, which is designed to characterize the safety and pharmacokinetic (PK)/pharmacodynamic (PD) profile of FPT155 and identify a recommended dose for the Phase 1b portion of the trial.

Cabiralizumab (anti-CSF1R) is an antibody that inhibits CSF1R and has been shown to block the activation and survival of tumor-associated macrophages. Pursuant to a worldwide collaboration agreement, Bristol-Myers Squibb (BMS) has an exclusive worldwide license for the development and commercialization of cabiralizumab, and Five Prime retains the rights to a U.S. co-promotion option.

  • Bristol-Myers Squibb has completed enrollment in the randomized Phase 2 trial testing the combination of cabiralizumab with Opdivo® (nivolumab) with and without chemotherapy in approximately 160 patients with locally advanced or metastatic pancreatic cancer that has progressed during or after one line of chemotherapy.
  • The next anticipated event from the Phase 2 trial is the announcement of actionable data from BMS in 2020.

BMS-986258 (anti-TIM-3) is a fully-human monoclonal antibody targeting TIM-3 (T cell immunoglobulin and mucin domain-3), an immune checkpoint receptor that may limit the duration and magnitude of T cell responses. This is the first clinical candidate from the discovery collaboration between Five Prime and BMS that includes targets in three immune checkpoint pathways.

  • The Phase 1/2 clinical trial continues to progress, with the expected size of the trial increased to 383 patients in July 2019.

Corporate Highlights

  • In October, the company announced a corporate restructuring to extend its cash runway without impacting or delaying the data timelines of its clinical programs. The company will retain a small research group focused on advancing three wholly-owned, late-stage research programs.
  • In September, the company’s board of directors appointed William Ringo as interim Chief Executive Officer in addition to his position as Chairman of the Board of Directors.

Summary of Financial Results and Guidance:

Cash Position: Cash, cash equivalents and marketable securities totaled $186.0 million as of September 30, 2019, compared to $214.1 million as of June 30, 2019. The decrease in cash, cash equivalents and marketable securities was primarily attributable to quarterly operating expenses that exceeded quarterly revenues.

Revenue: Collaboration and license revenue for the third quarter of 2019 decreased by $2.8 million, or 48.3%, to $3.0 million from $5.8 million for the third quarter of 2018. This decrease was primarily related to the completion of the research term under the immuno-oncology research collaboration with BMS in March 2019 and from progress made towards the company’s performance obligation under the original collaboration agreement.

R&D Expenses: Research and development expenses for the third quarter of 2019 decreased by $17.8 million, or 39.8%, to $26.9 million from $44.7 million for the third quarter of 2018. This decrease was primarily due a one-time milestone payment triggered by the dosing of the first patient in the Phase 3 FIGHT trial in the third quarter of 2018. Lower compensation costs, pre-clinical and research activities, manufacturing and diagnostic expenses and the reduction in the use of temporary resources contributed to the decrease and were partially offset by increased clinical trial expense to advance the company’s bemarituzumab, FPA150, and FPT155 clinical programs.

G&A Expenses: General and administrative expenses for the third quarter of 2019 increased by $3.4 million, or 34.7%, to $13.2 million from $9.8 million for the third quarter of 2018. The increase was primarily due to increased compensation costs offset by a reduction in the use of temporary resources.

Net Loss: Net loss for the third quarter of 2019 was $36.1 million, or $1.03 per basic and diluted share, compared to a net loss of $47.2 million, or $1.37 per basic and diluted share, for the third quarter of 2018.

Shares Outstanding: Weighted average shares outstanding for the third quarter of 2019 was 34,996,298 as of September 30, 2019.

Cash Guidance: Five Prime expects full-year 2019 net cash used in operating activities to be between $117 and $122 million and estimates ending 2019 with cash, cash equivalents and marketable securities between $148 and $153 million.
