RESEARCH TRIANGLE PARK, N.C., Feb. 24, 2021 (GLOBE NEWSWIRE) -- G1 Therapeutics, Inc. (Nasdaq: GTHX), a commercial-stage oncology company, today provided a corporate and financial update for the fourth quarter and full-year ended December 31, 2020.

“With the recent approval of COSELA, we have a tremendous opportunity to introduce an effective and innovative therapy to proactively address chemotherapy-induced myelosuppression in patients with extensive-stage small cell lung cancer,” said Jack Bailey, Chief Executive Officer of G1 Therapeutics. “The launch is underway with our partners at Boehringer Ingelheim, and the initial interest among medical oncologists and oncology nurses is extremely promising. COSELA has a broad mechanism of action, and as such, we are taking a tumor-agnostic approach to the development of COSELA as we advance it into and through multiple Phase 2 and registrational studies. We are confident in the potential for COSELA and look forward to delivering on our goal of improving the lives of as many people living with cancer as possible.”  

Fourth Quarter 2020 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). It is the first and only therapy designed to help protect bone marrow (myeloprotection) when administered prior to the start of chemotherapy. COSELA is expected to be commercially available through G1’s specialty distributor partner network in early March. (Press release here)

Clinical

  • Initiated Pivotal Trial of COSELA in Patients with First Line Colorectal Cancer in the Fourth Quarter of 2020: Patient enrollment has begun in a ~300 patient randomized, double-blind placebo-controlled pivotal registrational trial of COSELA in colorectal cancer. The primary endpoint is myelosuppression; secondary endpoints include progression free survival, overall survival, and patient reported outcomes. The data readout is expected in the first half of 2023.
  • Announced New Upcoming Registrational Trial of COSELA in First-line / Second Line Metastatic Triple-Negative Breast Cancer (mTNBC); Initiation Expected in First Half of 2021: The Company expects to initiate a randomized, double-blind placebo-controlled registrational trial of COSELA in mTNBC in the first half of 2021. The trial is expected to enroll approximately 250 participants, with approximately 170 in the first line cohort. The trial will enroll patients who are both PD-L1-positive and PD-L1-negative in the first-line cohort. The primary endpoint is overall survival; secondary endpoints include patient-reported outcomes measures, safety/tolerability, myeloprotective measures, and progression-free survival. (Press release here)
  • Announced Two Upcoming Phase 2 Trials of COSELA in First-Line Metastatic Bladder Cancer (mUC) and Second Line / Third Line Non-Small Cell Lung Cancer (NSCLC); Initiation Expected in the First Half 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 first half of 2021. Both trials are designed to evaluate the anti-tumor efficacy of COSELA.
  • Entered into Clinical Trial Collaboration for Upcoming First-Line Locally Advanced or Metastatic Bladder Cancer (mUC) Trial: G1 has entered into 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.
  • Presented Final Data from the Randomized Phase 2 Trial of COSELA in mTNBC at the 2020 San Antonio Breast Cancer Symposium (SABCS): New data presented at the SABCS meeting showed that COSELA significantly improved overall survival (OS) in patients with mTNBC treated with COSELA prior to administration of a chemotherapy regimen of gemcitabine/carboplatin (GC) compared with GC alone, and that COSELA enhanced immune system function. Compared to GC alone (Group 1), statistically significant improvements in OS were achieved in both COSELA arms (Group 2: HR=0.31, p=0.0016; Group 3: HR=0.40, p=0.0004). As of the data cutoff of July 17, 2020, the median OS was 12.6 months in patients receiving GC alone, not yet reached for Group 2, and 17.8 months in Group 3. The median OS for Groups 2 and 3 combined was 19.8 months (HR=0.37, p<0.0001). Patients with both PD-L1-positive and PD-L1-negative tumors treated with COSELA and GC demonstrated improvement in OS compared to patients receiving GC alone, with the PD-L1-positive subset achieving statistically significant improvement. Data from T-cell clonality analysis suggest that administering COSELA prior to chemotherapy enhanced immune system function. (Poster here)
  • Presented Updated Results from Phase 1b Monotherapy Trial of Rintodestrant in ER+, HER2- Breast Cancer at the 2020 SABCS: In a heavily pre-treated patient population, G1’s oral selective estrogen receptor degrader (SERD) rintodestrant showed evidence of clinical activity as monotherapy, including a clinical benefit rate of 30%. Safety and tolerability findings across all doses, including the 600 mg and 1,000 mg expansion cohorts, were consistent with previously reported data. These findings supported the Company’s decision to move the 800mg dose into the ongoing 40-patient Phase 2 combination trial with CDK4/6 inhibitor palbociclib. The data readout is expected in the second quarter of 2021. (Poster here)

Corporate

  • On February 23, 2021, the Board of Directors adopted the G1 Therapeutics, Inc. 2021 Inducement Equity Incentive Plan (the “Plan”). There are 500,000 shares of our common stock reserved under the Plan to be used exclusively for grants of awards to individuals that were not previously employees or directors of G1, as an inducement material to the individual’s entry into employment with G1 within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. The Plan was approved by Board of Directors without stockholder approval pursuant to Rule 5635(c)(4), and the terms and conditions of the Plan are substantially similar to G1’s stockholder-approved 2017 Equity Incentive Plan, as amended.

Fourth Quarter and Full Year 2020 Financial Results

As of December 31, 2020, cash and cash equivalents totaled $207.3 million, compared to $269.2 million as of December 31, 2019.

Subsequent to December 31, 2020, between January 14th, 2021 and February 9th, 2021, we sold 3,513,027 shares of common stock pursuant to our 2018 sales agreement for “at the market offerings” with Cowen and Company, LLC, resulting in $86.4 million in net proceeds. This ATM offering is now closed. In addition, the Company now has access to $30 million of the remaining $80M of our debt financing facility with Hercules Capital upon achievement of the FDA approval of COSELA milestone.

License revenue for the fourth quarter of 2020 was $16.5 million, primarily related to an upfront payment for our license agreement with Simcere recognized following the transfer of the related technology and know-how which occurred during the period. In addition, we recognized revenue for existing inventory transfers related to our license agreements with Genor and EQRx, as well as revenue for reimbursable clinical trial costs due from EQRx. License revenue for the full-year 2020 was $45.3 million.

Operating expenses for the fourth quarter of 2020 were $40.6 million, compared to $36.6 million for the fourth quarter of 2019. GAAP operating expenses include stock-based compensation expense of $4.8 million for the fourth quarter of 2020, compared to $4.5 million for the fourth quarter of 2019. Operating expenses for the full-year 2020 were $141.8 million, compared to $129.0 million for the prior year. Stock-based compensation expense for the full-year 2020 was $18.8 million, compared to $16.4 million for the prior year.

Research and development (R&D) expenses for the fourth quarter of 2020 were $16.4 million, compared to $24.5 million for the fourth quarter of 2019. The decrease in R&D expenses was primarily due to decreases in clinical program costs, external costs related to discovery and preclinical development, and costs for manufacturing pharmaceutical active ingredients. R&D expenses for the full-year 2020 were $73.3 million, compared to $89.0 million for the prior year.

General and administrative (G&A) expenses for the fourth quarter of 2020 were $24.3 million, compared to $12.1 million for the fourth quarter of 2019. The increase in G&A expenses was largely due to an increase in compensation due to increases in headcount, pre-commercialization activities, medical affairs costs, and professional fees and other administrative costs necessary to support our operations. G&A expenses for the full-year 2020 were $68.5 million, compared to $40.0 million for the prior year.

The net loss for the fourth quarter of 2020 was $25.3 million, compared to $35.4 million for the fourth quarter of 2019. Net loss for the full-year 2020 was $99.3 million, compared to a net loss of $122.4 million for the prior year. The basic and diluted net loss per share for the fourth quarter of 2020 was $(0.67) compared to $(0.94) for the fourth quarter of 2019. The basic and diluted net loss per share for the full-year 2020 was $(2.62) compared to $(3.27) for the full-year 2019.
