Geron Corporation Reports Second Quarter 2022 Financial Results

Top-Line Results from IMerge Phase 3 Trial in Lower Risk MDS Continue to be Expected in Early January 2023

Current and Projected Financial Resources Expected to Support Planned Milestones and Operations Through Middle of 2024

Conference Call Scheduled for 4:30 p.m. ET Today

Geron Corporation (Nasdaq: GERN), a late-stage clinical biopharmaceutical company developing a first-in-class telomerase inhibitor, imetelstat, to treat hematologic malignancies, today reported financial results for the second quarter of 2022 and key upcoming expected milestones.

“We continue to focus intently on our plans for a catalyst-rich next two years, during which we expect to transform Geron from a development stage to commercial company,” said John A. Scarlett, M.D., Geron’s Chairman and Chief Executive Officer. “Our plan to disclose Phase 3 top-line results in lower risk MDS remains on track for early January 2023. Assuming positive top-line results, U.S. and EU regulatory submissions are also planned in the first and second half of 2023, respectively. In addition, we expect to continue the stage-gated buildout of our commercial capabilities and key talent across our organization to support a potential commercial U.S. launch of imetelstat in the first half of 2024.”

“In order to maintain a strong balance sheet, we also recently amended our existing loan facility to secure up to $50 million in additional non-dilutive capital, which we expect to be available in 2023,” Dr. Scarlett continued. “With these potential added debt proceeds, we believe our current and projected financial resources will be sufficient to fund our expected level of operations until the middle of 2024.”

Key Upcoming Expected Milestones

• IMpactMF interim analysis in 2024

Pipeline expansion in additional indications and treatment combinations

• Start IMpress investigator-led study of single-agent imetelstat in relapsed/refractory (R/R) acute myeloid leukemia (AML) and higher risk MDS in the second half of 2022
• Start TELOMERE investigator-led Phase 1/2 study of imetelstat in combination with hypomethylating agents (HMAs) or venetoclax in R/R AML in the second half of 2022
• Initial preclinical lymphoid malignancies data by year-end 2022
• Preliminary data from IMproveMF Phase 1 study of imetelstat in combination with ruxolitinib in frontline myelofibrosis by year-end 2023

Additional Projected Financial Resources

In April 2022, the Company closed an underwritten public offering of common stock and warrants. The net cash proceeds from this offering were approximately $70 million, after deducting the underwriting discount and other offering expenses. The Company could receive up to $51.8 million in additional funding from the potential exercise of warrants from this offering, as well as up to $72.5 million from the potential exercise of warrants from an underwritten public offering that closed in May 2020.

In June 2022, the Company expanded its existing loan facility with Hercules Capital, Inc. and Silicon Valley Bank, from up to $75 million to up to $125 million. This amendment of the debt facility provides up to $50 million in additional non-dilutive capital, potentially available in 2023.

Of the aggregate $125 million loan facility, $50 million is currently outstanding. The remaining $75 million is potentially available to Geron in four tranches. The first tranche of $20 million is available until September 15, 2023, subject to the achievement of certain clinical and financial milestones. The second tranche of $10 million is available to the Company through December 15, 2023, subject to the achievement of certain clinical and regulatory milestones, and satisfaction of certain capitalization requirements. The third tranche of $20 million is available to the Company from September 15, 2023 until September 15, 2024, subject to the achievement of certain clinical and regulatory milestones, and satisfaction of certain capitalization requirements. The final tranche of $25 million is available to the Company through year-end 2024, subject to approval from the lenders.

Current and Projected Financial Resources

As of June 30, 2022, the Company had approximately $220 million in cash and marketable securities.

Under current planning assumptions, the Company projects its existing capital resources plus projected future proceeds of up to approximately $124 million from the potential exercise of the currently outstanding warrants and up to $50 million from the recently amended debt facility will be sufficient to fund Geron’s estimated level of operations, which includes stage-gated activities for potential U.S. commercial launch of imetelstat in lower risk MDS, until the middle of 2024.

Second Quarter 2022 Results

For the second quarter of 2022, the Company reported a net loss of $28.1 million, or $0.07 per share, compared to $29.6 million, or $0.09 per share, for the comparable 2021 period. Net loss for the first six months of 2022 was $58.2 million, or $0.16 per share, compared to $57.4 million, or $0.18 per share, for the comparable 2021 period.

Revenues for the three and six months ended June 30, 2022, were $73,000 and $196,000, respectively, compared to $107,000 and $244,000 for the comparable 2021 periods. Revenues in both years primarily reflect estimated royalties from sales of cell-based research products from the Company’s divested stem cell assets.

Total operating expenses for the three and six months ended June 30, 2022, were $28.0 million and $56.8 million, respectively, compared to $29.0 million and $57.6 million for the comparable 2021 periods.

Research and development expenses for the three and six months ended June 30, 2022, were $20.6 million and $42.7 million, respectively, compared to $21.9 million and $43.1 million for the comparable 2021 periods. The decrease in research and development expenses for the three and six months ended June 30, 2022, compared to the same periods in 2021 primarily reflects the net result of decreased manufacturing costs due to the timing of imetelstat manufacturing batches; partially offset by increased personnel-related expenses for additional headcount and higher consulting costs related to preparation for top-line results and regulatory submissions in lower risk MDS.

General and administrative expenses for the three and six months ended June 30, 2022, were $7.4 million and $14.1 million, respectively, compared to $7.1 million and $14.5 million for the comparable 2021 periods. The increase in general and administrative expenses for the three months ended June 30, 2022, compared to the same period in 2021, primarily reflects the net result of increased costs for commercial preparatory activities and higher personnel-related expenses for additional headcount; partially offset by lower legal fees and reduced consulting costs related to modernizing the internal infrastructure to support potential commercial launch. The decrease in general and administrative expenses for the six months ended June 30, 2022, compared to the same period in 2021, primarily reflects the net result of reduced consulting costs and lower legal fees; partially offset by higher personnel-related expenses.

Interest income was $330,000 and $442,000 for the three and six months ended June 30, 2022, respectively, compared to $136,000 and $309,000 for the same periods in 2021. The increase in interest income for the three and six months ended June 30, 2022, compared to the same periods in 2021, primarily reflects a larger marketable securities portfolio with the receipt of net cash proceeds from the underwritten public offering completed in April 2022 and higher yields from recent marketable securities purchases.

Interest expense was $1.6 million and $3.1 million for the three and six months ended June 30, 2022, respectively, compared to $804,000 and $1.5 million for the same periods in 2021. The increase in interest expense for the three and six months ended June 30, 2022, compared to the same periods in 2021, primarily reflects rising interest rates and increased principal debt balance. Currently, the Company has $50.0 million in principal debt outstanding.

Net other income was $1.1 million for each of the three and six months ended June 30, 2022, respectively, compared to net other expense of $17,000 and net other income of $1.2 million for the same periods in 2021. In the second quarter of 2022, the Company recognized other income of approximately $1.3 million related to the reimbursement of certain legal expenses under its insurance policies. During the first quarter of 2021, the Company sold all of its holdings in an equity investment resulting in a net realized gain of $1.2 million, including foreign currency translation adjustments.

Projected 2022 Financial Guidance Reaffirmed

For fiscal year 2022, under generally accepted accounting principles (GAAP), the Company continues to expect total operating expenses in the range of approximately $155 million to $165 million, which includes non-cash items such as: stock-based compensation expense, amortization of debt discounts and issuance costs, as well as depreciation and amortization. The Company continues to expect non-GAAP total operating expenses for fiscal year 2022 in the range of approximately $140 million to $150 million, which excludes estimated non-cash items such as: stock-based compensation expense, amortization of debt discounts and issuance costs, as well as depreciation and amortization.

The fiscal year 2022 financial guidance reflects costs to support: (a) preparatory activities for top-line results from the IMerge Phase 3 clinical trial and readiness for potential regulatory submissions and commercialization of imetelstat in lower risk MDS; (b) continued conduct of IMerge and IMpactMF and commencement of new clinical studies associated with the imetelstat pipeline expansion strategy; (c) finalizing validation batches of imetelstat at contract manufacturers to enable future production of imetelstat for clinical and commercial purposes; (d) projected increases in headcount and (e) interest payments on outstanding debt.

As of June 30, 2022, the Company had 86 employees. The Company plans to grow to a total of approximately 90 to 100 employees by year-end 2022.

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic malignancies. Data from Phase 2 clinical trials provide strong evidence that imetelstat targets telomerase to inhibit the uncontrolled proliferation of malignant stem and progenitor cells in myeloid hematologic malignancies resulting in malignant cell apoptosis and potential disease-modifying activity. Imetelstat has been granted Fast Track designation by the United States Food and Drug Administration for both the treatment of patients with non-del(5q) lower risk MDS who are refractory or resistant to an erythropoiesis stimulating agent and for patients with Intermediate-2 or High-risk MF whose disease has relapsed after or is refractory to janus associated kinase (JAK) inhibitor treatment.

About IMerge Phase 3

IMerge Phase 3 is a double-blind, randomized, placebo-controlled Phase 3 clinical trial with registrational intent. The trial is designed to enroll approximately 170 transfusion dependent patients with Low or Intermediate-1 risk myelodysplastic syndromes (MDS), also referred to as lower risk MDS, who have relapsed after or are refractory to prior treatment with an erythropoiesis stimulating agent (ESA). The primary endpoint is the rate of red blood cell (RBC) transfusion independence (TI) for any consecutive period of eight weeks or longer, or 8-week RBC-TI rate. Key secondary endpoints include the rate of RBC-TI lasting at least 24 weeks, or 24-week RBC-TI rate, duration of TI and the rate of hematologic improvement-erythroid (HI-E), defined as a reduction of at least four units of RBC transfusions over eight weeks compared with the prior RBC transfusion burden.

IMerge Phase 3 is fully enrolled and patient enrollment has been closed. For additional information about IMerge Phase 3, visit ClinicalTrials.gov/NCT02598661.

About IMpactMF Phase 3

IMpactMF is an open label, randomized, controlled Phase 3 clinical trial with registrational intent. The trial is designed to enroll approximately 320 patients with Intermediate-2 or High-risk myelofibrosis (MF) who are refractory to prior treatment with a JAK inhibitor, also referred to as refractory MF. Patients will be randomized to receive either imetelstat or best available therapy. The primary endpoint is overall survival (OS). Key secondary endpoints include symptom response, spleen response, progression free survival, complete remission, partial remission, clinical improvement, duration of response, safety, pharmacokinetics, and patient reported outcomes.

IMpactMF is currently enrolling patients. For further information about IMpactMF, including enrollment criteria, locations and current status, visit ClinicalTrials.gov/NCT04576156.
