RESEARCH TRIANGLE PARK, N.C., May 05, 2021 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today provided a corporate and financial update for the first quarter ended March 31, 2021.

“The first quarter of 2021 was a transformational period for G1 as the approval and availability of COSELA provided extensive-stage small cell lung cancer patients undergoing chemotherapy with the first proactive multilineage myeloprotection therapy to help prevent myelosuppression,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “COSELA represents an opportunity to shift the treatment paradigm away from reactive treatments with multiple different single lineage therapeutic interventions. Our commercial team has demonstrated that we can effectively launch and deliver the drug during a very challenging time. Further, though very early in the launch period, leading and lagging indicators from the first four weeks of availability are encouraging and suggest that the awareness and interest in COSELA is strong, that it is being accepted by oncologists and oncology nurses, and that it is being well covered by payers. Another important step during the quarter was the inclusion of COSELA in two sets of NCCN Guidelines, which are the standard resource for determining best course of treatment and supportive care for people living with cancer. We also maintained clinical momentum in our tumor-agnostic development program for COSELA, including the initiation of PRESERVE 2, our Phase 3 registrational trial in triple-negative breast cancer.”  

First Quarter 2021 and Recent Highlights

Commercial

• COSELA Approved by U.S. Food and Drug Administration (FDA): On February 12, 2021, the FDA approved COSELA for injection to decrease the incidence of chemotherapy-induced myelosuppression in adult patients when administered prior to a platinum/etoposide-containing regimen or topotecan-containing regimen for extensive-stage small cell lung cancer (ES-SCLC). (Press release here)
• COSELA Now Available in the U.S.: On March 2, 2021, G1 and its commercial partner Boehringer Ingelheim announced that COSELA was available through G1’s specialty distributors Amerisource Specialty Distribution, Oncology Supply, McKesson Plasma and Biologics, McKesson Specialty and Cardinal Specialty. (Press release here)

Medical

• COSELA Added to Two National Comprehensive Cancer Network^® (NCCN) Clinical Practice Guidelines in Oncology (NCCN Guidelines^®): On March 25, 2021, G1 announced that COSELA had been added to the Treatment Guidelines for Small Cell Lung Cancer and to the Supportive Care Guidelines for Hematopoietic Growth Factors. These guidelines document evidence-based, consensus-driven management to ensure that all patients receive preventive, diagnostic, treatment, and supportive services that are most likely to lead to optimal outcomes. (Press release here)
• Presented New Budget Impact Data for COSELA at the Academy of Managed Care Pharmacy (AMCP) Meeting: These data described a model that compared ES-SCLC treatment scenarios with and without COSELA. The incremental cost of COSELA to a third-party payer is projected to be entirely offset by a reduction in the costs of managing adverse events related to myelosuppression. Therefore, the use of COSELA is estimated to provide cost savings.

Clinical

• Initiated Pivotal Trial of COSELA in Patients Receiving First or Second Line Gemcitabine and Carboplatin Chemotherapy for Locally Advanced Unresectable or Metastatic Triple-Negative Breast Cancer (mTNBC): Patient enrollment is underway in PRESERVE 2, a randomized, double-blind, placebo-controlled Phase 3 registrational trial of COSELA in patients receiving first- or second-line gemcitabine/carboplatin (GC) chemotherapy for locally advanced unresectable or metastatic TNBC. (Press release here)
• Entered Clinical Trial Collaboration for Upcoming First Line Locally Advanced or Metastatic Bladder Cancer (mUC) Trial of COSELA: G1 entered a clinical trial collaboration with the alliance between Merck KGaA, Darmstadt, Germany and Pfizer whereby the alliance will contribute clinical supply of the checkpoint inhibitor avelumab to the G1-sponsored and funded first-line mUC trial.
• On Track to Initiate Two Phase 2 Trials of COSELA in First Line Metastatic Bladder Cancer (mUC) and Second Line / Third Line Non-Small Cell Lung Cancer (NSCLC) in the Second Quarter of 2021: The Company expects to initiate Phase 2 trials of COSELA in first-line treatment of locally advanced or metastatic bladder cancer (locally advanced or metastatic urothelial carcinoma, or mUC) and second- and third-line treatment of NSCLC, both of which are known immunogenic tumors, in the second quarter of 2021. Both trials are designed to evaluate the anti-tumor efficacy of COSELA.
  

First Quarter 2021 Financial Results

As of March 31, 2021, cash and cash equivalents totaled $279.0 million, compared to $207.3 million as of December 31, 2020. This includes $86.4 million in net proceeds in the first quarter from the “At the Market” offering with Cowen and Company, LLC. This ATM offering is now closed. In addition, the Company drew the additional $10M available in the first tranche of debt on its debt financing facility with Hercules Capital. The Company has access to an additional $70 million through this facility.

Total revenue for the first quarter of 2021 was $14.2 million, including approximately $0.6 million in initial net product sales of COSELA and license revenue of $13.6 million, primarily related to development milestone payments from the Company’s license agreement with Simcere and revenue from EQRx related to delivery of clinical drug supply and manufacturing services and reimbursement of clinical trial costs with EQRx. In addition, the Company recognized revenue related to achievement of a development milestone by Genor.

Operating expenses for the first quarter of 2021 were $39.8 million, compared to $31.8 million for the first quarter of 2020. GAAP operating expenses include stock-based compensation expense of $5.9 million for the first quarter of 2021, compared to $4.7 million for the first quarter of 2020.

Cost of goods sold expense for the first quarter of 2021 were $0.2 million, compared to $0 for first quarter of 2020. The increase related to the Company’s period costs for the sales of COSELA.

Research and development (R&D) expenses for the first quarter of 2021 were $16.5 million, compared to $20.4 million for the first quarter of 2020. The decrease in R&D expenses was primarily due to a decrease in costs for manufacturing of active pharmaceutical ingredients and drug product to support clinical trials, as well as a decrease in external costs related to discovery and pre-clinical development.

Selling, general and administrative (SG&A) expenses for the first quarter of 2021 were $23.0 million, compared to $11.4 million for the first quarter of 2020. The increase in SG&A expenses was largely due to an increase in compensation due to increases in headcount and increased commercialization activities.

The net loss for the first quarter of 2021 was $26.4 million, compared to $31.0 million for the first quarter of 2020. The basic and diluted net loss per share for the first quarter of 2021 was $(0.65) compared to $(0.82) for the first quarter of 2020.
