RESEARCH TRIANGLE PARK, N.C., Nov. 03, 2021 (GLOBE NEWSWIRE) --  G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today provided a corporate and financial update for the third quarter ended September 30, 2021.

“The third quarter of 2021 was a period of rapid execution on initiatives designed to maximize the current and future opportunity of COSELA for patients, physicians, and investors,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “We believe COSELA is a paradigm-changing drug. In just a matter of months, we have a number of important drivers such as exceptional reimbursement, high awareness and intention to treat, and excellent physician experience. However, our recent sales were impacted by less-than-optimal execution and access challenges at key accounts that treat up to 50 percent of patients diagnosed with small cell lung cancer. We are moving aggressively to address this, including by the deployment of a supplemental sales force to target these largest accounts. Longer term, our clinical programs are strategically designed to maximize the potential of trilaciclib and meaningfully improve the lives of people living with cancer, including our plans to initiate two new Phase 2 trials this quarter. We expect these studies to add to our broader development effort to demonstrate the potential of trilaciclib with therapies likely to be relevant in future treatment paradigms.”   

Third Quarter 2021 and Recent Highlights


  • Achieved Net COSELA™ (trilaciclib) Revenue of $3.6 Million.
  • Ended the Third Quarter of 2021 with Cash and Cash Equivalents of $212.1 million.
  • Upsized Debt Facility with Hercules Capital: The Hercules loan terms were amended to provide total commitments of $150 million, with $100 million fully available as November 1, 2021. The Company’s current financial position is expected to be sufficient to fund G1’s operations and capital expenditures into 2024.


  • Announced New Supplemental COSELA Sales Force: G1 is in the process of hiring and training up to 15 people for the Company’s supplemental oncology sales force. The expansion will allow G1 to target top tier accounts to accelerate sales activities and help maximize the adoption of COSELA. The new G1 sales representatives will supplement the existing Boehringer Ingelheim oncology commercial team. (Press release here)
  • Permanent J-code for COSELA Effective for Provider Billing as of October 1, 2021: The permanent J-code that was issued in July 2021 by the Centers for Medicare & Medicaid Services (CMS) is now effective for provider billing for all sites of care. All hospital outpatient departments, ambulatory surgery centers and physician offices in the United States now have one consistent Healthcare Common Procedure Coding System (HCPCS) code to standardize the submission and payment of COSELA insurance claims across Medicare, Medicare Advantage, Medicaid and commercial plans. The New Technology Add-on Payment (NTAP) for COSELA when administered to Medicare beneficiaries in the hospital inpatient setting is also effective. (Press release here)


  • Initiation of New Phase 2 Study of Trilaciclib to Support its Immune-based Mechanism of Action Expected in 4Q21: The Company confirmed its expectation to initiate a Phase 2 study of trilaciclib and chemotherapy in patients with early-stage triple negative breast cancer (TNBC) in the fourth quarter of 2021 to further investigate the role of trilaciclib in modulating the anti-tumor immune response.
  • Initiation of New Phase 2 Study of Trilaciclib in Combination with an Antibody-Drug Conjugate (ADC) in Triple-Negative Breast Cancer Expected in 4Q21: G1 intends to initiate a Phase 2 single arm study of trilaciclib administered prior to an ADC in patients with unresectable locally advanced or metastatic TNBC in the fourth quarter of 2021.
  • Received Fast Track designation for Trilaciclib for Use in in Triple-Negative Breast Cancer (TNBC): The U.S. Food and Drug Administration (FDA) granted Fast Track designation to trilaciclib for use in combination with chemotherapy for the treatment of locally advanced or metastatic triple negative breast cancer. Trilaciclib is currently being evaluated in PRESERVE 2, a pivotal Phase 3, randomized, double-blind, placebo-controlled study in patients receiving first- or second-line gemcitabine and carboplatin chemotherapy for TNBC. (Press release here)
  • NSCLC Market Changes Drive Strategic Decision to Discontinue Phase 2 Trial of Trilaciclib in 2L/3L NSCLC and Shift Resources to New Phase 2 MOA and ADC Trials: The future treatment paradigm in 2L/3L NSCLC is expected to shift further away from docetaxel, the chemotherapy backbone in PRESERVE 4, suggesting minimal future market opportunity in this setting. As such G1 is discontinuing this trial and shifting those resources to support the new Phase 2 MOA and ADC trials
  • Initiation of Investigator Initiated Study (IIS) of Trilaciclib in 1L Non-Small Cell Lung Cancer (NSCLC) Expected in 1Q22: As part of its broad investigator-initiated study program, G1 expects to support an IIS assessing the anti-tumor efficacy of trilaciclib in first-line NSCLC in combination with chemo and a checkpoint inhibitor.

Third Quarter 2021 Financial Results

As of September 30, 2021, cash and cash equivalents totaled $212.1 million, compared to $207.3 million as of December 31, 2020. On November 1, 2021, G1 and Hercules Capital amended Hercules’ loan terms to provide total commitments of $150 million, of which $100 million was fully available as of amendment closing. The Company has drawn down $75 million in total from the Hercules debt facility; $30 million had been drawn as of the end of the quarter and an additional $45 million was drawn on November 1, 2021.

Total revenues for the third quarter of 2021 were $4.9 million, including $3.6 million in net product sales of COSELA and license revenue of $1.3 million. This license revenue is primarily related to clinical trial reimbursements from EQRx and Simcere, and delivery of clinical drug supply and manufacturing services to Simcere, EQRx and Genor.

Operating expenses for the third quarter of 2021 were $46.0 million, compared to $36.3 million for the third quarter of 2020. GAAP operating expenses include stock-based compensation expense of $5.5 million for the third quarter of 2021, compared to $4.9 million for the third quarter of 2020.

Cost of goods sold expense for the third quarter of 2021 were $0.6 million, compared to $0 for third quarter of 2020. The increase related to the Company’s period costs for the sales of COSELA, including third-party logistics costs for the sales of COSELA, inventory overhead costs, and personnel costs.

Research and development (R&D) expenses for the third quarter of 2021 were $21.1 million, compared to $17.9 million for the third quarter of 2020. The increase in R&D expenses was primarily due to an increase in clinical trial spend, which is offset by a decrease in costs associated with the manufacturing of active pharmaceutical ingredients and drug product to support clinical trials.

Selling, general and administrative (SG&A) expenses for the third quarter of 2021 were $24.3 million, compared to $18.4 million for the third quarter of 2020. The increase in SG&A expenses was largely due to an increase in commercialization activities, an increase in compensation due to increases in headcount, increased spend on medical affairs costs related to trilaciclib and information technology, professional services, and other administrative costs.

The net loss for the third quarter of 2021 was $42.5 million, compared to $11.7 million for the third quarter of 2020. The basic and diluted net loss per share for the third quarter of 2021 was $(1.00) compared to $(0.31) for the third quarter of 2020.

Financial Guidance

Including the contribution from the amended Hercules agreement, the Company expects its current financial position to be sufficient to fund its operations and capital expenditures into 2024.
