Release Details

MENLO PARK, Calif., March 07, 2019 (GLOBE NEWSWIRE) -- Geron Corporation (Nasdaq: GERN) today reported financial results for the fourth quarter and full year ended December 31, 2018 and recent events. As of year-end 2018, the Company had approximately $182 million in cash and marketable securities, which is sufficient to commence the planned Phase 3 clinical trial of imetelstat in lower risk myelodysplastic syndromes (MDS) by mid-year 2019.
 

“We expect 2019 to be a pivotal year,” said John A. Scarlett, M.D., Chairman and Chief Executive Officer. “We are making good progress in the transition of the imetelstat program and expect to assume sponsorship of the imetelstat clinical trials by the end of the second quarter. We continue planning to open the Phase 3 clinical trial of imetelstat in lower risk MDS for enrollment by mid-year, as well as evaluating the potential for late-stage development in MF. In addition, we expect to further expand our team with individuals who have strong development expertise that will enable us to build a robust hematology-oncology franchise.”

Recent Events

Building a Development Team with Hematology-Oncology Expertise

The Company recently announced the hiring of two key development executives. Aleksandra Rizo, M.D., Ph.D., the former clinical lead for the imetelstat program at Janssen, joined Geron as Chief Medical Officer. Israel Gutierrez, M.D., who has more than 20 years of oncology clinical development experience, joined Geron as Vice President, Pharmacovigilance and Drug Safety. In addition, Geron plans to open an office in northern New Jersey to access experienced personnel with late-stage hematology-oncology clinical drug development expertise, as well as to enable efficient support for global clinical trials, including the Phase 3 clinical trial of imetelstat in lower risk MDS. 

Fourth Quarter 2018 Highlights

IMerge Phase 2 Data Presented Support Initiation of Phase 3 Trial in Lower Risk MDS

Data for the Phase 2 portion of IMerge were presented in an oral presentation at the American Society of Hematology (ASH) annual meeting on December 2, 2018. Geron believes these data support initiating the Phase 3 portion of IMerge to address an unmet medical need for patients for whom erythropoiesis stimulating agents (ESAs) are not effective and for whom currently available therapies show only modest efficacy, especially in patients with high baseline transfusion burdens who are difficult-to-treat. Lower risk MDS patients in the U.S. represent a large unmet need as there has not been a new drug approved by the Food and Drug Administration (FDA) since 2006.

In the Phase 2 portion of IMerge, 38 patients were enrolled who were transfusion dependent with Low or Intermediate-1 risk non-del(5q) MDS who have relapsed after or are refractory to prior treatment with an ESA and naïve to treatment with a hypomethylating agent (HMA) or lenalidomide. In the trial, transfusion dependence is defined as a patient requiring a minimum of four units of red blood cells (RBC) over a consecutive 8-week time period to treat anemia. The median baseline RBC transfusion burden in the Phase 2 portion of IMerge was eight units per eight weeks, ranging from four to 14 units. The primary efficacy endpoint of the trial is the rate of RBC transfusion-independence (RBC TI) lasting at least eight weeks (8-week RBC TI rate), which is defined as the proportion of patients who are transfusion free for at least eight consecutive weeks since entry into the trial. Key secondary endpoints include durability of response as evidenced through 24-week RBC TI rate and breadth of response through reduction in RBC transfusion burden and rate of RBC transfusions, as well as responses across MDS sub-types.
 

Primary Efficacy Endpoint:

• 37% (14/38) of patients achieved an 8-week RBC TI rate

Secondary Efficacy Endpoints:

Durability

• 26% (10/38) of patients achieved a 24-week RBC TI rate

Transfusion Reduction

• The rate of hematologic improvement-erythroid (HI-E) was 71% (27/38), as measured by a reduction of at least four RBC units over eight weeks compared with prior transfusion burden
• Mean relative reduction of RBC transfusion burden from baseline was 68%

Broad Clinical Activity Observed

• Similar 8-week RBC TI rates were observed in patients with baseline serum erythropoietin (sEPO) levels less than or greater than 500mU/mL
• 8-week RBC TI rates were also consistent between ringed-sideroblast (RS) positive patients and other patients

The ASH presentation reported data based on a data cut-off date of October 26, 2018. As of the data cut-off date, the median duration of RBC TI had not been reached. Geron expects more mature data from patients continuing on treatment in the Phase 2 portion of IMerge to be available in 2019 and anticipates submitting such data for presentation at a future medical conference.

IMbark Phase 2 Data Presented Suggest Meaningful Survival Outcome in Relapsed/Refractory MF Patients

Data from the Phase 2 IMbark clinical trial, including new overall survival data, were presented in an oral presentation at ASH on December 3, 2018.

The IMbark trial evaluated two starting dose levels of imetelstat (either 4.7 mg/kg or 9.4 mg/kg administered by intravenous infusion every three weeks) in more than 100 patients with Intermediate-2 or High-risk myelofibrosis (MF) who were relapsed or refractory to janus kinase inhibitor (JAKi) therapy. To be eligible for enrollment in the IMbark trial, patients had to meet rigorous criteria for having failed or not responded to JAKi treatment, including documented progressive disease during or after JAKi therapy. The ASH presentation highlighted efficacy and safety data from the trial’s primary analysis, as well as overall survival (OS) data with a clinical cutoff of October 22, 2018 and a median follow up of 27 months.

The ASH presentation reported that the median OS for the 9.4 mg/kg dosing arm was 29.9 months, which suggests a meaningful survival outcome with imetelstat treatment in this poor-prognosis, relapsed/refractory patient population where there are currently no approved treatments today. Other observational studies of similar patient populations at academic medical centers published recently in medical literature have reported median OS ranges of approximately 12 to 14 months after failure of or discontinuation of ruxolitinib, a JAKi.

Geron plans to discuss the potential for late-stage development of imetelstat in MF with current IMbark investigators, other key opinion leaders (KOLs) and regulatory authorities. The Company expects to facilitate KOL discussions over the coming months. Discussions with regulatory authorities are expected to begin after the investigational new drug (IND) sponsorship has been transferred back to Geron.

The Company plans to outline a decision regarding the potential for future late-stage development in MF by the end of the third quarter of 2019. In making this decision, Geron will conduct an assessment of what would be required to achieve clinical and regulatory success, including the cost and duration of any potential clinical trials.

Imetelstat Safety Results

The safety profile reported in both ASH presentations for imetelstat-treated patients was consistent with prior clinical trials of imetelstat in hematologic malignancies, and no new safety signals were identified. Cytopenias, particularly neutropenia and thrombocytopenia, were the most frequently reported adverse events, which were predictable, manageable and reversible.

Fourth Quarter and Year-End 2018 Results

For the fourth quarter of 2018, the company reported a net loss of $7.3 million, or $0.04 per share, compared to $7.4 million, or $0.05 per share, for the comparable 2017 period. For 2018, the company reported a net loss of $27.0 million, or $0.15 per share, compared to $27.9 million, or $0.18 per share, for 2017.

Revenues for the fourth quarter of 2018 were $375,000 compared to $191,000 for the comparable 2017 period. Revenues for 2018 and 2017 were each $1.1 million and included royalty and license fee revenues under various non-imetelstat license agreements. The Company adopted a new revenue recognition accounting standard as of January 1, 2018 using the modified retrospective transition method. Revenue for 2018 is presented under the new accounting standard, but revenue for 2017 has not been adjusted and continues to be reported under accounting standards used historically. Therefore, there is a lack of comparability between the periods presented. However, the Company does not expect the adoption of the new revenue recognition accounting standard to have a material impact to its financial statements on an ongoing basis.

Total operating expenses for the fourth quarter of 2018 were $10.0 million compared to $8.0 million for the comparable 2017 period. Total operating expenses for 2018 were $32.1 million compared to $30.3 million for 2017.

Research and development expenses for the fourth quarter of 2018 were $5.1 million compared to $2.5 million for the comparable 2017 period. Research and development expenses for 2018 were $13.4 million compared to $11.0 million for 2017. The increase in research and development expenses for the fourth quarter and year-to-date 2018 periods compared to comparable 2017 periods primarily reflects increases in Geron’s share of imetelstat development costs under the former collaboration agreement with Janssen Biotech, Inc. (Janssen) where Geron’s share increased from 50% to 100% as of the termination date of the collaboration agreement and additional costs for the contract research organization (CRO) and other consultants for the transition of the imetelstat program from Janssen to Geron.

General and administrative expenses for the fourth quarter of 2018 were $4.9 million compared to $5.5 million for the comparable 2017 period. General and administrative expenses for 2018 were $18.7 million compared to $19.3 million for 2017. The decrease in general and administrative expenses in 2018 compared to 2017 primarily reflects the net result of reduced personnel related expenses, including lower stock-based compensation expense, partially offset by higher consulting expenses and higher patent legal expenses with the termination of the imetelstat collaboration with Janssen, as imetelstat patent costs previously were being shared by the two companies on a 50/50 basis.

Interest and other income for the fourth quarter of 2018 was $1.1 million compared to $375,000 for the comparable 2017 period. Interest and other income for 2018 was $3.3 million compared to $1.4 million for 2017. The increase in interest and other income for 2018 compared to 2017 primarily reflects higher yields on the Company’s marketable securities portfolio.

Planned 2019 Activities and Milestones

Geron’s plans for 2019 primarily focus on advancing imetelstat development. The Company believes building a development team with hematology-oncology expertise is essential to executing the Phase 3 clinical trial in lower risk MDS and evaluating the potential for late-stage development in MF, as well as in the future, exploring additional indications for imetelstat and being able to pursue other innovative therapeutics in hematology-oncology. Geron expects the following activities and milestones to occur in 2019:

Transition of Imetelstat Development Program

• Complete the transfer of the IND back to Geron by the end of the second quarter.
  
   
• Complete the transfer of the imetelstat clinical development program back to Geron by the end of the third quarter.
  
   
• Actively recruit highly-experienced personnel with drug development expertise in myeloid malignancies.

MDS Development

• Commence screening and enrollment for the Phase 3 portion of IMerge by mid-year.
  
   
• Present more mature data from patients in the Phase 2 portion of IMerge at a medical conference.

MF Development

• Conduct discussions with IMbark investigators, other MF KOLs and regulatory authorities to identify and consider potential late-stage clinical development plans for relapsed/refractory MF patients.
  
   
• Outline decision regarding the potential for late-stage development of imetelstat in MF by the end of the third quarter.

Projected 2019 Financial Guidance

The Company expects its operating expenses to increase as it assumes full responsibility for the development and potential commercialization of imetelstat. For fiscal year 2019, the Company expects its operating expense burn to range from $65 to $70 million, of which approximately $10 to $15 million represents one-time costs, such as imetelstat program transition activities from Janssen to Geron, including the transfer of the IND sponsorship, and purchase of raw materials and other supplies in preparation for new drug manufacturing. In addition to the one-time costs, projected 2019 operating expense guidance includes costs for the expansion of the internal development team, the global Phase 3 clinical trial in MDS and the opening of the New Jersey office. The Company plans to grow to a total of approximately 30 to 40 employees by year-end 2019, of which half will be research and development personnel.

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic myeloid malignancies. Early clinical data suggest imetelstat may have disease-modifying activity through the suppression of malignant progenitor cell clone proliferation, which allows potential recovery of normal hematopoiesis. Ongoing clinical studies of imetelstat include a Phase 2/3 trial called IMerge in lower risk myelodysplastic syndromes (MDS) and a Phase 2 trial called IMbark in Intermediate-2 or High-risk myelofibrosis. Imetelstat has been granted Fast Track designation by the United States Food and Drug Administration for the treatment of patients with transfusion-dependent anemia due to lower risk MDS who are non-del(5q) and refractory or resistant to an erythroid stimulating agent.
