"The second quarter of 2022 was a period of continued momentum across the G1 organization toward our mission of improving the lives of those impacted with cancer," said Jack Bailey, Chief Executive Officer of G1 Therapeutics. "For the first time, our sales team was in full control of COSELA, interacting with prescribers and driving usage and uptake. Thanks to the quality of these engagements, we experienced nearly 60 percent vial volume growth quarter over quarter – our highest quarterly growth rate since the initial launch period. In addition, our clinical team continued to execute on each of our ongoing clinical trials, including achieving important enrollment milestones in our Phase 3 trial of trilaciclib in patients with colorectal cancer and in our Phase 2 bladder cancer and mechanism of action trials."

Second Quarter 2022 and Recent Highlights

Financial

Achieved $8.7 Million in Net COSELA Revenue: G1 recognized total revenues of $10.6 million in the second quarter of 2022, including $8.7 million in net product revenue from sales of COSELA.
Ended the Second Quarter 2022 with Cash and Cash Equivalents of $144.0 Million: The Company’s current financial position is expected to be sufficient to fund G1’s operations and capital expenditures into 2024.
Clinical

Completed Enrollment in Pivotal Phase 3 Clinical Trial of Trilaciclib in Patients with mCRC: Enrollment in PRESERVE 1 is complete at 326 randomized patients; the trial was over-enrolled by approximately 10 percent to compensate for potential loss to follow up at trial sites in Ukraine. The primary endpoint is myeloprotection as measured by duration of severe neutropenia and the occurrence of severe neutropenia during induction. Key secondary endpoints include the effects of trilaciclib on chemotherapy-induced fatigue compared with placebo and the effect of trilaciclib on progression free survival and overall survival compared with placebo. Initial data including the primary endpoint of myeloprotection are expected in the first quarter of 2023. (Press release here)
Completed Enrollment in Phase 2 Clinical Trial Assessing the Mechanism of Action (MOA) of Trilaciclib in Neoadjuvant Breast Cancer: Enrollment is complete at 24 patients in the Phase 2 trial in early stage TNBC to confirm the mechanism of action of trilaciclib in modulating the anti-tumor immune response. The primary endpoints will assess the immune-based MOA, including the impact of trilaciclib on CD8+ T cells and regulatory T cells, or Tregs, in the tumor microenvironment. Secondary endpoints include pathological complete response (pCR), immune response, and profiling measures. Initial data from the primary endpoint are expected in the fourth quarter of 2022.
Achieved Target Patient Enrollment in Phase 2 Clinical Trial of Trilaciclib in Combination with Chemotherapy and Avelumab in Patients with Bladder Cancer (mUC): Target enrollment of 90 patients was achieved in PRESERVE 3; the last few consented patients are expected to enroll shortly. The trial builds on the strong rationale for trilaciclib in combination with chemotherapy and a checkpoint inhibitor (anti-PD-L1); preclinical and published data to date suggest potential for a synergistic effect in known immunogenic tumors. The primary endpoint is progression-free survival. Key secondary endpoints include overall survival, overall response rate, duration of response, and myeloprotection. Initial data including top line response rate and myeloprotection data are expected in the fourth quarter of 2022 followed by data on the primary endpoint of progression free survival in 2023.
Confirmed Expectation for Initial Data from Pivotal Phase 3 Trial of Trilaciclib in Triple Negative Breast Cancer (mTNBC) in the Second Half of 2023: Initial results including interim results for Overall Survival from PRESERVE 2, the Company’s ongoing line extension trial of trilaciclib in approximately 170 patients with PD-L1 positive and negative metastatic TNBC receiving first line gemcitabine and carboplatin, are expected in the second half of 2023. If the trial meets the interim analysis stopping rule, it will terminate, and we will report the topline results. If it does not, the trial will continue to the final analysis.
Confirmed Expectation for Initial Data in the Fourth Quarter of 2022 from Phase 2 Trial of Trilaciclib in Combination with an Antibody-Drug Conjugate (ADC): G1 has reiterated that it expects to release preliminary safety data in the fourth quarter of 2022 from a Phase 2 trial in combination with the antibody-drug conjugate (ADC) Trodelvy (sacituzumab govitecan-hziy) in patients with unresectable locally advanced or metastatic TNBC.
Medical

Presented Data at the 2022 ASCO (Free ASCO Whitepaper) Annual Meeting Showing that Trilaciclib Helps Protect Patients with Extensive-Stage Small Cell Lung Cancer (ES-SCLC) Against Single- and Multilineage Myelosuppressive Events When Used Prior to Chemotherapy: Results of the analysis showed that throughout cycles one through four of first-line therapy, fewer patients with ES-SCLC treated with trilaciclib experienced single-lineage (neutrophil, red blood cell or platelet lineages) and multilineage myelosuppressive events (severe neutropenia, severe anemia, and severe thrombocytopenia)—and fewer events occurred per person—than patients who received placebo. (Press release here)
Presented Data at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Describing the Economic Impact of Trilaciclib for Chemotherapy-Induced Myelosuppression in ES-SCLC): Data showed that from both the US provider and patient-caregiver perspectives, the use of trilaciclib prior to chemotherapy in patients with ES-SCLC is associated with fewer myelosuppressive AEs and less healthcare resource use, translating into lower total cost of care.

Second Quarter 2022 Financial Results

As of June 30, 2022, cash and cash equivalents totaled $144.0 million, compared to $221.2 million as of December 31, 2021.

Total revenues for the second quarter of 2022 were $10.6 million, including $8.7 million in net product sales of COSELA and license revenue of $1.9 million. This license revenue is primarily related to revenue recognized from amounts to be reimbursed by EQRx and Simcere for costs associated with clinical trials.

Operating expenses for the second quarter of 2022 were $47.5 million, compared to $44.8 million for the second quarter of 2021. GAAP operating expenses include stock-based compensation expense of $5.6 million for the second quarter of 2022, compared to $5.7 million for the second quarter of 2021.

Cost of goods sold expense for the second quarter of 2022 was $1.0 million compared to $0.8 million for the second quarter of 2021, primarily due to an increase in product sales.

Research and development (R&D) expenses for the second quarter of 2022 were $20.8 million, compared to $18.8 million for the second quarter of 2021. The increase in R&D expenses was primarily due to an increase in clinical trial costs offset by a decrease in costs for manufacturing of active pharmaceutical ingredients and drug product to support clinical trials.

Selling, general, and administrative (SG&A) expenses for the second quarter of 2022 were $25.7 million, compared to $25.2 million for the second quarter of 2021. The increase in SG&A expenses was due to increased personnel costs related to headcount and an increase in insurance and other administrative costs. The increase is offset by a decrease in medical affairs costs, commercialization activities, professional and legal fees, and IT-related costs.

The net loss for the second quarter of 2022 was $39.4 million, compared to $39.4 million for the second quarter of 2021. The basic and diluted net loss per share for the second quarter of 2022 was $(0.92) compared to $(0.94) for the second quarter of 2021.

Financial Guidance

G1 expects its current cash and cash equivalents of $144.0 million to be sufficient to fund its operations and capital expenditures into 2024.
