"Data from our Phase 2 TNBC trial of trilaciclib in combination with chemotherapy showed clinically meaningful and substantial improvements in overall survival as well as enhanced measures of immune system function compared to chemotherapy alone," said Raj Malik, M.D., Chief Medical Officer at G1 Therapeutics. "Those preliminary data support the important role trilaciclib may play in treating cancer by enhancing T cell activation and favorably altering the tumor microenvironment. This Phase 2 clinical study will support trilaciclib’s mechanistic effects potentially responsible for enhanced anti-tumor immune responses in patients and generate important data that will help guide our future development decisions across additional tumor types and new treatment combinations."

Patient recruitment in this trial is now underway. Approximately 30 patients will be enrolled in this Phase 2 multicenter, open-label, single-arm, neoadjuvant study. Up to three tumor tissue samples will be collected for assessment. Tumor tissue will be obtained at baseline prior to study drug administration. Patients will receive a single dose of monotherapy trilaciclib, followed by a tumor biopsy approximately one week later. Following the biopsy, patients will enter the treatment phase in which trilaciclib will be administered on Day 1 of each cycle of anthracycline/cyclophosphamide for four cycles followed by trilaciclib administered on Day 1 of each weekly cycle of taxane chemotherapy for 12 cycles. Immune checkpoint inhibitor and/or carboplatin may be added to therapy at the discretion of the investigator. Three to five weeks after the last dose of chemotherapy, patients will proceed to surgery at which time a third tumor tissue sample will be collected if the patient has residual disease.

Study treatment will continue as per protocol to completion or early discontinuation of chemotherapy, until unacceptable toxicity, Investigator’s decision to withdraw the patient from study treatment, consent withdrawal, or the end of the study, whichever occurs first.

The primary objective is to evaluate the immune-based mechanism of action of trilaciclib after a single-dose as measured by the change in the ratio of CD8+ tumor-infiltrating lymphocytes (TILs) to regulatory T cell (Tregs) in the tumor microenvironment. Key secondary and exploratory endpoints include:

Assessment of pathologic complete response (pCR) rate at the time of definitive surgery.
Evaluation of the safety and tolerability of trilaciclib in combination with standard neoadjuvant systemic therapies.
Tumor mRNA analyses and immunohistochemistry and peripheral blood immune profiling following trilaciclib.
Identification of molecular and cellular biomarkers in tumor or blood samples that may be indicative of clinical response/resistance, pharmacodynamic activity, and/or the mechanism of action of trilaciclib and other systemic treatments.
About Triple Negative Breast Cancer (TNBC)
According to the American Cancer Society, nearly 300,000 new cases of invasive breast cancer are diagnosed annually in the U.S. Triple-negative breast cancer makes up approximately 15-20% of such diagnosed breast cancers. TNBC is cancer that tests negative for estrogen receptors, progesterone receptors, and excess HER2 protein. Because mTNBC cells lack key growth-signaling receptors, patients do not respond well to medications that block estrogen, progesterone, or HER2 receptors. Instead, treating mTNBC typically involves chemotherapy, radiation, and surgery. TNBC is considered to be more aggressive and have a poorer prognosis than other types of breast cancer. In general, survival rates tend to be lower with mTNBC compared to other forms of breast cancer, and mTNBC is also more likely than some other types of breast cancer to return after it has been treated, especially in the first few years after treatment. It also tends to be higher grade than other types of breast cancer.

68Ga PSMA-11 (~200MBq, left) vs. 64Cu SAR-bisPSMA (~200MBq, right) in the same patient; time between serial imaging was 8 days. Standardised Uptake Value (SUVmax)* of the lesions were 6.5 and 6.3 for 68Ga PSMA-11 and 16.5 and 18.5 for 64Cu SAR-bisPSMA

*SUV is a measurement of product uptake in tissue normalised to a distribution volume

Clarity’s Executive Chairman, Dr Alan Taylor, commented, "We are excited to have quickly and successfully recruited half of the patients planned for the PROPELLER trial with all three sites actively recruiting and imaging prostate cancer patients across Australia. We have been able to not only generate strong preliminary clinical data since the trial commencement in July 2021, but also validate our on-demand distribution model where the 64Cu-SAR-bisPSMA has been shipped to the trial sites across Australia from a central manufacturing facility with minimal delays or interruptions. The pace and quality of work that we were able to achieve during this trial is reflective of the appetite for the new generation of radiopharmaceuticals that can cater to large indications in the oncology space and shift the radiopharmaceutical field towards the "big pharma" model with central manufacture of ready-to-use products. This shift has potential to significantly improve patient care by focusing on the needs of patients and enable their treating staff to access critical treatments that are safe and efficacious, on time and at any treatment centre with a positron emission tomography (PET) camera."

The PROPELLER trial is a Phase I Positron Emission Tomography (PET) imaging trial of participants with confirmed prostate cancer using 64Cu SAR-bisPSMA. It is a 30-patient multi-centre, blinded review, dose ranging, non-randomised study of 64Cu-SAR-bisPSMA administered to patients with confirmed prostate cancer prior to radical prostatectomy (NCT04839367)1. The main goals of the PROPELLER trial are to:

Determine the safety and tolerability of 64Cu SAR-bisPSMA in participants with untreated, confirmed prostate cancer and planned for radical prostatectomy;
Examine 64Cu SAR-bisPSMA at different dose levels;
Determine the ability of 64Cu SAR-bisPSMA to detect primary prostate cancer; and
Compare diagnostic properties of 64Cu SAR-bisPSMA against 68Ga PSMA-11, the standard of care for prostate cancer imaging in Australia.
Prof Louise Emmett (St Vincent’s Hospital Sydney), Principal Investigator in the PROPELLER trial commented, "The preliminary data from the patients imaged in the PROPELLER trial to date looks very promising as it supports the evidence of higher uptake of 64Cu SAR-bisPSMA in the tumours that has been shown in the pre-clinical studies. Higher uptake in the tumours means that they are more visible on the PET scans and hence have a higher chance of being detected. These initial results are encouraging for further development of this product as a diagnostic, and the higher uptake and retention also make it an exciting therapeutic target with 67Cu. In addition to the anticipated clinical benefits, having access to centrally manufactured products has the potential to improve patient care by providing an alternative to currently used short-lived diagnostic radioisotopes, such as 68Ga and 18F, the production of which can pose challenges in delivering critical imaging scans to patients with cancer on time. I am very pleased to be working with Clarity on the Targeted Copper Theranostics (TCT) platform of products, having recently completed the C-BOBCAT trial of SAR-Bombesin, in hopes that these products will improve the current treatment paradigm for oncology patients."

Dr Alan Taylor further commented, "Clarity is well on track to explore and validate the benefits of the TCT platform, including the logistical, manufacturing and treatment benefits associated with the "perfect pairing" of copper-64 and copper-67. These benefits hold promise of providing a large patient population with early, accurate and precise detection of prostate cancer. As such, we look forward to recruiting the remaining 50% of patients and generating more data to validate the compelling results from our preclinical studies as well as the exciting preliminary results from the PROPELLER trial and our US-based 64/67Cu SAR-bisPSMA theranostic trial (SECuRE trial (NCT04868604)2) in pursuit of our ultimate goal of improving treatment outcomes for children and adults with cancer."

This announcement has been authorised for release by the Executive Chairman.
