Geron Q2 2025 presentation: RYTELO sales climb 24%, stock jumps premarket

Introduction & Market Context

Geron Corporation (NASDAQ:GERN) presented its Q2 2025 earnings on August 6, 2025, reporting significant growth in RYTELO sales and progress in its clinical pipeline. The biotech company’s stock jumped 11.67% in premarket trading to $1.34, signaling investor confidence after previous quarters of share price pressure.

The presentation, led by Interim CEO Dawn Bir and incoming CEO Harout Semerjian, highlighted a 24% quarter-over-quarter increase in RYTELO sales, with the telomerase inhibitor gaining traction in the myelofibrosis treatment landscape.

Quarterly Performance Highlights

Geron reported Q2 2025 RYTELO net product revenue of $49.0 million, a substantial improvement from the $39.6 million reported in Q1 2025 that had previously disappointed analysts. The company highlighted several key performance metrics showing growing market penetration.

As shown in the following performance metrics chart:

The company reported approximately 17% demand increase in Q2 2025 compared to Q1, with around 1,000 ordering accounts since approval. Notably, about 400 new accounts were added year-to-date, suggesting accelerating adoption. Approximately 30% of new RYTELO patient starts are occurring in first and second line treatment, potentially indicating broader usage beyond later-stage patients. The company also highlighted that about 90% of covered lives are under plans with favorable RYTELO coverage policies, addressing previous concerns about reimbursement barriers.

Commercial Strategy

Geron outlined a three-pronged commercial strategy aimed at building on Q2’s momentum. The plan focuses on increasing healthcare provider awareness, improving prescribing confidence, and generating key opinion leader support.

The commercial plan of action includes specific initiatives as illustrated here:

The company is refining its prescriber targeting and has increased field sales headcount, with additional clinical educators to support physician education. Digital marketing campaigns and regional case study programs are being implemented to improve prescriber confidence. The presentation noted that Q2 2025 performance was achieved by the existing commercial team, suggesting potential for further growth as the expanded sales force becomes fully operational by year-end.

Medical (TASE:BLWV) Affairs Strategy

Complementing the commercial initiatives, Geron is significantly expanding its medical affairs capabilities to support RYTELO’s growth trajectory:

The medical affairs strategy mirrors the commercial approach with expanded Medical Liaison headcount aligned with sales regions and the addition of health economics and outcomes research (HEOR) leadership. The company is doubling its medical affairs headcount to support expanded key opinion leader engagement, education, and medical information dissemination—all critical elements for building physician confidence in a relatively new therapy.

Clinical Development Updates

Geron provided an encouraging update on its Phase 3 IMpactMF trial for relapsed/refractory myelofibrosis, a potential catalyst for future growth:

The trial has reached over 95% enrollment as of July 2025, with full enrollment expected by year-end. This positions the company for an interim analysis in the second half of 2026, with final analysis anticipated in the second half of 2028. The IMpactMF trial is significant as it’s the first trial evaluating overall survival as a primary endpoint in relapsed/refractory myelofibrosis, potentially differentiating RYTELO in an increasingly competitive market.

Financial Analysis

The financial overview revealed both strengths and ongoing challenges:

Geron reported a cash balance of $432.6 million as of June 30, 2025, representing a decrease from the $457.5 million reported at the end of Q1 2025. This continued cash burn reflects the significant investment in commercial infrastructure and ongoing clinical development. Q2 operating expenses totaled $61.5 million, with full-year 2025 expenses projected between $270 million and $285 million, consistent with previous guidance.

While the revenue growth is encouraging, the company’s cash burn rate remains a consideration for investors, particularly as Geron continues to invest heavily in commercial expansion and clinical development.

Forward-Looking Statements

Looking ahead, Geron’s management expressed confidence in the commercial trajectory of RYTELO, with the expanded sales force expected to drive further growth by year-end. The company’s near-term focus remains on the U.S. commercial launch of RYTELO, while the IMpactMF trial represents a significant potential catalyst in 2026.

The premarket stock movement of +11.67% suggests investors are responding positively to the revenue growth and clinical progress, a marked contrast to the 7.04% decline following Q1 results. However, with the stock still trading near its 52-week low of $1.09, Geron faces the challenge of demonstrating sustainable commercial momentum to restore investor confidence in its long-term prospects.

As the company transitions to new leadership under incoming CEO Harout Semerjian, maintaining commercial execution while managing cash resources will be critical to Geron’s success in the competitive oncology landscape.
