RESEARCH TRIANGLE PARK, N.C., May 04, 2022 (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, 2022.

“The first quarter of 2022 was a period of transition and execution across the G1 business,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “In March of this year, we entered a new phase for COSELA promotion as we transitioned fully away from our commercial launch partner Boehringer Ingelheim and put the promotion of COSELA into the hands of our newly deployed G1 sales team; the strong month over month sales performance in March adds to the evidence of good early access to key accounts by our team. Our sales and commercial teams are now fully engaged in driving depth in key top organizations. Regarding our clinical programs, we are approaching a data-rich period, as we currently expect initial results from each of our ongoing Phase 2 and Phase 3 trials over the coming 18 months, starting with data from our three Phase 2 trials in the fourth quarter of this year.”

First Quarter 2022 and Recent Highlights


  • Achieved Total Revenue of $6.9 Million: G1 recognized total revenues of $6.9 million in the first quarter of 2022, including $5.5 million in net product revenue from sales of COSELA.
  • Ended the First Quarter 2022 with Cash and Cash Equivalents of $183.0 Million: The Company’s current financial position is expected to be sufficient to fund G1’s operations and capital expenditures into 2024.


  • Fully Deployed COSELA Sales Team: On March 2, 2022, the co-promotion agreement for COSELA between G1 and Boehringer Ingelheim was terminated. As of February 15, 2022, G1 had fully deployed its sales team into regions across the U.S. to accelerate sales activities and help maximize the adoption of COSELA.


  • Reiterated Expectation of Initial Data in the Fourth Quarter of 2022 from Three Phase 2 Trials of Trilaciclib: G1 has reiterated that it expects to release initial data from multiple ongoing Phase 2 clinical trials of trilaciclib in the fourth quarter of 2022. These trials include a Phase 2 trial of trilaciclib in combination with avelumab in bladder cancer; a Phase 2 trial in combination with the antibody-drug conjugate (ADC) Trodelvy® (sacituzumab govitecan-hziy) in patients with unresectable locally advanced or metastatic triple-negative breast cancer (TNBC); and a Phase 2 trial designed to confirm the mechanism of action of trilaciclib in modulating the anti-tumor immune response with and without a checkpoint inhibitor in early stage TNBC.  
  • Reiterated Expectation of Initial Data in 2023 from Two Phase 3 Trials of Trilaciclib: G1 expects to release data from two ongoing pivotal Phase 3 clinical trials of trilaciclib in 2023. Initial results including myeloprotection and Objective Response Rate (ORR) endpoints from PRESERVE 1, our ongoing line extension trial of trilaciclib in patients with colorectal cancer (CRC) receiving first line trilaciclib or placebo administered prior to FOLFOXIRI and bevacizumab, are expected in the first quarter of 2023. Initial results including interim results for Overall Survival (OS) from PRESERVE 2, our ongoing line extension trial of trilaciclib in PD-L1 positive and negative patients with TNBC receiving first line gemcitabine and carboplatin, are expected in the second half of 2023.


  • Presented New Real-World Data at the Annual Conference of the National Comprehensive Cancer Network (NCCN) Showing the Impact of Trilaciclib on Hospitalizations and the Burden of Myelosuppression in Patients with ES-SCLC Treated with Chemotherapy: Results showed that the use of trilaciclib prior to chemotherapy was associated with a 50% reduction in the percent of patients with grade ≥ 3 myelosuppressive hematologic adverse events in at least one blood cell lineage and a 74% reduction in the percent of all-cause hospitalizations (days 1 to 21 after treatment), compared to patients who received chemotherapy alone. The analyses were derived using structured, real-world, de-identified clinical patient level data from the Integra Connect oncology warehouse. (Press release here)
  • Published Data in Cancer Treatment and Research Communications Showing Treatment Patterns and the Burden of Myelosuppression for Patients with Small Cell Lung Cancer (SCLC): Results of this retrospective study showed that 42 percent of small-cell lung cancer patients failed to complete the recommended number of chemotherapy cycles, and 74 percent of patients were admitted to the hospital due to a myelosuppressive event, thus underscoring the burden of myelosuppression. Additionally, health care resource utilization associated with myelosuppression was prominent, suggesting a substantial burden on older patients with SCLC. These data were derived from a descriptive, retrospective study of patients with SCLC aged ≥65 years, identified from linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data.

  • Strategic Decision Made to Discontinue the Rintodestrant Program: After completing our evaluation of the rintodestrant partnering options and recent data in the highly competitive oral SERD space, G1 has made the strategic decision to discontinue the program, including all clinical and partnering efforts. G1 will responsibly wind down all remaining clinical efforts for rintodestrant by the end of this year and revert the rights back to the originator (University of Illinois Chicago); there are no additional financial obligations due to the originator resulting from the reversion.

First Quarter 2022 Financial Results

As of March 31, 2022, cash and cash equivalents totaled $183.0 million, compared to $221.2 million as of December 31, 2021.

Total revenues for the first quarter of 2022 were $6.9 million, including $5.5 million in net product sales of COSELA and license revenue of $1.4 million. This license revenue is primarily related to clinical trial reimbursements from EQRx and Simcere.

Operating expenses for the first quarter of 2022 were $53.7 million, compared to $39.8 million for the first quarter of 2021. GAAP operating expenses include stock-based compensation expense of $5.8 million for the first quarter of 2022, compared to $5.9 million for the first quarter of 2021.

Cost of goods sold expense for the first quarter of 2022 were $0.7 million compared to $0.2 for the first quarter of 2021. The increase is 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 first quarter of 2022 were $26.3 million, compared to $16.5 million for the first quarter of 2021. The increase in R&D expenses was driven by an increase in clinical trial spend related to increased activity in all of our clinical trials including an acceleration of enrollment in our Phase 3 CRC trial, which is partially 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 first quarter of 2022 were $26.7 million, compared to $23.0 million for the first quarter of 2021. The increase in SG&A expenses was largely due to an increase in personnel costs due to increased headcount, and an increase in professional services, insurance and other administrative costs.

The net loss for the first quarter of 2022 was $49.2 million, compared to $26.4 million for the first quarter of 2021. The basic and diluted net loss per share for the first quarter of 2022 was $(1.15) compared to $(0.65) for the first quarter of 2021.

G1 expects its current cash position of $183.0 million to be sufficient to fund its operations and capital expenditures into 2024.
