RESEARCH TRIANGLE PARK, N.C., Aug. 04, 2021 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today provided a corporate and financial update for the second quarter ended June 30, 2021.

“The second quarter of 2021 was a period of solid progress across G1, as we seek to develop COSELA for patients suffering from a variety of cancers,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “In our first full quarter of sales of COSELA, the commercial team continued to build the commercial foundation for this important myeloprotection drug for patients with ES-SCLC undergoing chemotherapy. We believe that COSELA is a paradigm-changing product, allowing cancer patients to be treated proactively to reduce the impact of the multilineage myelosuppression side effects of chemotherapy. So far, the enthusiasm for COSELA is encouraging. We also initiated three new COSELA clinical trials during the second quarter, including a registrational trial in metastatic TNBC and two Phase 2 trials, one in NSCLC and the other in bladder cancer. With the ongoing commercial launch, the expansion of our innovative tumor-agnostic pipeline, and a strong financial position, we are excited about the opportunities ahead for COSELA.”

Second Quarter 2021 and Recent Highlights

Financial

• Achieved Net COSELA (trilaciclib) Revenue of $2.5 Million.
• Ended the Second Quarter with Cash and Cash Equivalents of $244.0 million: The current financial position expected to be sufficient to fund G1’s operations and capital expenditures into 2023.

Medical

• Presented New Data Describing the Estimated Economic Impact of Treating Myelosuppression in Patients with ES-SCLC at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR): The first poster used a cost-benefit model to predict an estimated economic value from a general U.S. commercial payer perspective of using COSELA prior to chemotherapy in ES-SCLC to project a significant payer cost savings based on assumptions that myelosuppressive adverse events and their associated treatment costs would be reduced. The second poster quantified the significant health burden, economic toll, and health-related quality-of-life effects of chemotherapy-induced myelosuppression among Medicare patients diagnosed with SCLC. (Press release here)
• Presented Results of Analyses Evaluating the Immune Effects of COSELA in Patients with ES-SCLC at the American Society of Clinical Oncology (ASCO) annual meeting: Patients receiving COSELA prior to chemotherapy had greater peripheral T-cell clonal expansion than patients receiving placebo. The data suggest that, among patients treated with COSELA plus either etoposide and carboplatin (E/C) or E/C plus atezolizumab, increased clonal expansion is associated with clinical response, indicating that COSELA may enhance antitumor immunity in patients with ES-SCLC treated with chemotherapy. (Press release here)
• Presented Positive Data Suggesting Strong Safety Profile and Evidence of Antitumor Activity of Rintodestrant Combined with Palbociclib in ER+/HER- Advanced Breast Cancer at ASCO: In the 40-patient combination arm of the Phase 1 trial, rintodestrant was very well tolerated and did not result in additional or more severe toxicities when added to Palbociclib. The clinical benefit rate (CBR; percentage of patients with either confirmed complete or partial response or stable disease lasting ≥ 24 weeks) doubled from 30 percent with rintodestrant monotherapy to 60 percent with the combination of rintodestrant and Palbociclib; among patients with early relapse, the CBR was 73%.

Clinical

• Initiated Pivotal Trial of COSELA in Locally Advanced Unresectable or Metastatic TNBC: 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 chemotherapy for locally advanced unresectable or metastatic TNBC. (Press release here)
• Received Fast Track Designation for COSELA in TNBC: The FDA granted Fast Track designation to COSELA investigation for use in combination with chemotherapy for the treatment of locally advanced or metastatic TNBC. Fast track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill unmet medical needs. (Press release here)
• Initiated Phase 2 Trial of COSELA in Metastatic NSCLC: Patent enrollment is underway in PRESERVE 4, a randomized double-blind placebo-controlled Phase 2 trial of COSELA administered prior to docetaxel in patients with NSCLC in the 2nd and 3rd line setting who have previously been treated with a checkpoint inhibitor and chemotherapy. The primary endpoint of the trial is to evaluate the anti-tumor effect of COSELA on overall survival (OS) compared to placebo. (Press release here)
• Initiated Phase 2 Trial of COSELA in Bladder Cancer: Patent enrollment is underway in PRESERVE 3, a randomized double-blind placebo-controlled Phase 2 trial of COSELA administered with first-line platinum-based chemotherapy and the immune checkpoint inhibitor avelumab maintenance therapy in patients with untreated, locally advanced or metastatic urothelial carcinoma. (Press release here)

Corporate

• Announced Andrew Perry as Chief Commercial Officer: Mr. Perry, formerly the Vice President of US Marketing for ViiV Healthcare NA, brings nearly 25 years of leadership experience in commercial launch strategy, digital marketing, and co-promotion management to G1, with extensive capabilities in launching and growing brands in multiple areas including oncology.

Total revenues for the second quarter of 2021 were $6.6 million, including $2.5 million in net product sales of COSELA and license revenue of $4.1 million, primarily related to a development milestone payment from the Company’s license agreement with Simcere, clinical trial reimbursements from EQRx, and delivery of clinical drug supply and manufacturing services to Simcere, EQRx and Genor. Total revenues for the six months ended June 30, 2021 were $20.8 million.

Operating expenses for the second quarter of 2021 were $44.8 million, compared to $33.0 million for the second quarter of 2020.

Cost of goods sold expense for the second quarter of 2021 were $0.8 million, compared to $0 for second quarter of 2020. The increase related to the Company’s period costs for the sales of COSELA. Cost of goods sold for the six months ended June 30 was $1.1 million.

Research and development (R&D) expenses for the second quarter of 2021 were $18.8 million, compared to $18.5 million for the second 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, as well as external costs related to discovery and pre-clinical development. R&D expenses for the six months ended June 30 were $35.3 million.

Selling, general and administrative (SG&A) expenses for the second quarter of 2021 were $25.2 million, compared to $14.4 million for the second 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, and increased spend on information technology, professional services, and other administrative costs. SG&A expenses for the six months ended June 30 were $48.2 million.

The net loss for the second quarter of 2021 was $39.4 million, compared to $31.2 million for the second quarter of 2020.
