Results in the poster include:

Median overall survival (OS) for patients who received subsequent lines of anticancer therapy (SACT) after discontinuation of study treatment was 32.7 months for patients who had previously received trilaciclib prior to gemcitabine/carboplatin (GCb) compared to 12.8 months for patients who had previously received GCb only (no trilaciclib), with increasing separation of survival curves over time.
Improved survival and sustained separation of curves was also observed in patients unable to receive SACT, although the magnitude of benefit was smaller (median 9.4 months for patients who had previously received trilaciclib vs 5.4 months for patients who had previously received chemotherapy alone).
Notably, median OS from the start of the first SACT was 14.0 months in patients who had previously received trilaciclib prior to GCb compared to 5.8 months in patients who received GCb only (no trilaciclib).
For patients who received any SACT after discontinuation of study treatment, demographics and clinical characteristics including, time from end of study treatment to first SACT, and type of SACT were balanced between the prior trilaciclib (n=43) and prior GCb-only (n=20) groups.
"These results describe the long-term survival benefits of treatment with trilaciclib in patients with triple negative breast cancer that participated in our Phase 2 trial," said Raj Malik, M.D., Chief Medical Officer of G1 Therapeutics. "The survival benefit appears to extend well beyond the initial treatment with trilaciclib and chemotherapy. Importantly, patients who had previously received trilaciclib continue to benefit with subsequent therapies, resulting in substantially longer survival than patients who had previously received chemotherapy alone. We believe this is likely due to preservation of bone marrow and immune function, resulting in improved long term immune surveillance. We look forward to sharing these results with the oncology community, as we assess the impact of trilaciclib on overall survival in our ongoing pivotal Phase 3 mTNBC and Phase 2 ADC trials."

On November 29, 2023 Veracyte, Inc. (Nasdaq: VCYT) reported that clinical validation data published in the journal CHEST show that the company’s Percepta Nasal Swab test determines lung cancer risk, with high accuracy, among people who currently smoke or have previously smoked and have lung nodules (Press release, Veracyte, NOV 29, 2023, View Source [SID1234638049]). The findings suggest that the novel, non-invasive genomic test can help physicians guide next steps for these patients, enabling them to potentially avoid unnecessary invasive procedures or accelerate time to appropriate treatment.

Lung cancer is the leading cause of cancer death worldwide. Lung nodules are an early indicator of lung cancer and are typically found using computed tomography (CT) scans. In the United States, approximately 15 million people are eligible for annual lung cancer screening with low-dose CT scans based on their smoking history and other factors and currently an estimated 1.6 million lung nodules are found incidentally each year in patients being evaluated with a CT scan for an unrelated condition. While most lung nodules are not cancerous, their detection can result in unnecessary diagnostic procedures and anxiety for patients. At the same time, early detection of cancerous nodules can lead to better patient outcomes.

"Physicians need an objective, accurate tool to help guide care for patients when a lung nodule is found on a CT scan," said Bill Bulman, M.D., Veracyte’s medical director for Pulmonology and an author on the CHEST manuscript. "Our findings reinforce the ability of the Percepta Nasal Swab test to improve risk assessment of lung nodules and help avoid unnecessary diagnostic procedures for those at low risk of cancer while supporting timely diagnosis and treatment for those with high risk of cancer."

Veracyte’s Percepta Nasal Swab test is a simple, non-invasive genomic test that can be done in the physician’s office and is designed to assess lung cancer risk in patients who currently smoke or have previously smoked and have lung nodules found on CT scans. The test reports whether a patient has a high-, moderate- or low-risk for lung cancer, providing insights to help physicians objectively determine which patients with lung nodules to work up for lung cancer and which patients to simply monitor with imaging.

For the CHEST study, researchers used the Percepta Nasal Swab test, which was trained on a cohort of 1,120 patients with lung nodules that were either malignant or benign, to evaluate nasal samples from an independent cohort of 312 eligible patients followed for at least 12 months or until a final diagnosis of benign or malignant was determined.

Results show that the Percepta Nasal Swab test is highly accurate in identifying patients with low-risk nodules (97% sensitivity, with 40% specificity). This high sensitivity provides a negative predictive value, or NPV, of 98% in a population with a 25% cancer prevalence, meaning the test could assist physicians in avoiding unnecessary invasive procedures in patients with a benign nodule, with a very small risk of missing a cancer.

Similarly, researchers found that the test is highly accurate in identifying patients with high-risk nodules (92% specificity, with 57% sensitivity). This high specificity provides a positive predictive value, or PPV, of 70% in a population with a 25% cancer prevalence, meaning the test could assist physicians in directing these patients to further procedures so they could obtain an accurate diagnosis and speed time to treatment, if necessary.

The Percepta Nasal Swab test had consistently high performance across various groups of patients within the study cohort, including those with prior cancers and different lung cancer subtypes, lung nodule sizes (including nodules <8 mm), smoking histories and lung cancer screening eligibility, suggesting the test’s potential clinical value in a wide range of patients. In contrast, currently available physician risk calculators were developed with specific patient populations in mind and tend to perform unevenly across different types of patients.

"We believe our Percepta Nasal Swab test can be paradigm-changing in the evaluation of lung cancer risk among patients with lung nodules," said Dr. Bulman. "By helping to guide next steps for physicians and their patients, we aim to help make lung nodule evaluation, including through lung cancer screening programs, more efficient and effective."

Publication of the Percepta Nasal Swab test clinical validation study is an important step in Veracyte’s journey toward securing payer reimbursement for the test, prior to the test being made widely available. Additionally, the company is currently conducting a prospective clinical utility study, known as NIGHTINGALE, at hospitals and clinics around the United States to demonstrate the test’s ability to improve patient care and outcomes.

The Percepta Nasal Swab test was developed with RNA whole-transcriptome sequencing and machine-learning technology. It utilizes foundational "field of injury" science, which evaluates genomic changes associated with lung cancer that can be found in epithelial cells in the nasal passages of current and former smokers.

"Reaching target enrollment ex-mainland China in this important study represents a significant milestone for SELLAS, the GPS development program, and the AML patient community," said Angelos Stergiou, MD, ScD h.c., President and Chief Executive Officer of SELLAS. "We are extremely grateful to the participating patients and investigators who have helped achieve this critical milestone and we look forward to sharing the interim analysis which we expect to occur by the end of this year or early next year based upon our statistical assumptions. We are also looking forward to the upcoming IDMC meeting later this month. REGAL is the most comprehensive study conducted by a biotech company to date in this orphan disease setting. With a strong scientific rationale and supportive clinical data in previously conducted Phase 1 and Phase 2 studies in the AML maintenance setting, we believe GPS holds significant promise as a potential new treatment for AML patients. Furthermore, the positive outcome from the recently completed FDA Type C meeting and FDA’s guidance on the advancement of our CMC plans for a BLA filing, assuming positive results from the REGAL study, further strengthens our overall GPS program."

The Phase 3 open-label REGAL trial was designed with formal input from the United States Food and Drug Administration. Over 100 patients have been enrolled in the United States, Europe and Asia in the study which compares GPS monotherapy in the maintenance setting to investigators’ choice of best available treatment in AML patients who have achieved hematologic complete remission, with or without thrombocytopenia (CR2/CR2p), after second-line antileukemic therapy and who are deemed ineligible for or unable to undergo allogeneic stem-cell transplantation. The primary endpoint is overall survival (OS) from the time of study entry. Secondary endpoints include leukemia-free survival, antigen-specific T-cell immune response dynamics, measurable residual disease by multigene array, and assessments of AML clonal evolution and inflammasome molecular signatures in the tumor microenvironment in bone marrow biopsy samples.

Based upon the Company’s statistical assumptions, the interim analysis (after 60 events) is expected to occur in late 2023 or early 2024 and the final analysis (after 80 events) is on track to occur by the end of 2024. Because these analyses are event driven, they may occur at a different time than currently expected.

GPS has received Fast Track Designation in the United States and Orphan Drug Designation in both the United States and the European Union for AML.

On November 29, 2023 Panbela Therapeutics, Inc. (Nasdaq: PBLA), a clinical stage company developing disruptive therapeutics for the treatment of patients with urgent unmet medical needs, reported that the independent Data Safety Monitoring Board (DSMB) of the Phase 3 ASPIRE clinical trial for patients with untreated metastatic pancreatic ductal adenocarcinoma has completed its pre-specified review of safety data for treated patients which included 214 patients in the trial (Press release, Panbela Therapeutics, NOV 29, 2023, View Source [SID1234638044]). The DSMB has recommended that the study continue without modification. The ASPIRE Trial is a global randomized, doubleblind placebo-controlled clinical trial to evaluate ivospemin in combination with gemcitabine and nab-Paclitaxel in patients with metastatic pancreatic ductal adenocarcinoma. "We are pleased that no safety concerns were identified and the DSMB’s recommendation is to proceed without modification to the ASPIRE Trial. With a focus on enrollment and completing site initiations, we are looking forward to the interim analysis in mid-2024." said Jennifer K. Simpson, PhD, MSN, CRNP, President & Chief Executive Officer of Panbela.

About our Pipeline

The pipeline consists of assets currently in clinical trials with an initial focus on familial adenomatous polyposis (FAP), first-line metastatic pancreatic cancer, neoadjuvant pancreatic cancer, colorectal cancer prevention, ovarian cancer and diabetes. The combined development programs have a steady cadence of catalysts with programs ranging from pre-clinical to registration studies.

SBP-101 Ivospemin

Ivospemin is a proprietary polyamine analogue designed to induce polyamine metabolic inhibition (PMI) by exploiting an observed high affinity of the compound for pancreatic ductal adenocarcinoma and other tumors. It has shown signals of tumor growth inhibition in clinical studies of metastatic pancreatic cancer patients, demonstrating a median overall survival (OS) of 14.6 months and an objective response rate (ORR) of 48%, both exceeding what is typical for the standard of care of gemcitabine + nab-paclitaxel suggesting potential complementary activity with the existing FDA-approved standard chemotherapy regimen. In data evaluated from clinical studies to date, ivospemin has not shown exacerbation of bone marrow suppression and peripheral neuropathy, which can be chemotherapy-related adverse events. Serious visual adverse events have been evaluated and patients with a history of retinopathy or at risk of retinal detachment will be excluded from future SBP-101 studies. The safety data and PMI profile observed in the previous Panbela-sponsored clinical trials provide support for continued evaluation of ivospemin in the ASPIRE trial.

Flynpovi

Flynpovi is a combination of CPP-1X (eflornithine) and sulindac with a dual mechanism inhibiting polyamine synthesis and increasing polyamine export and catabolism. In a Phase 3 clinical trial in patients with sporadic large bowel polyps, the combination prevented > 90% subsequent pre-cancerous sporadic adenomas versus placebo. Focusing on FAP patients with lower gastrointestinal tract anatomy in the recent Phase 3 trial comparing Flynpovi to single agent eflornithine and single agent sulindac, FAP patients with lower GI anatomy (patients with an intact colon, retained rectum or surgical pouch), Flynpovi showed statistically significant benefit compared to both single agents (p≤0.02) in delaying surgical events in the lower GI for up to four years. The safety profile for Flynpovi did not significantly differ from the single agents and supports the continued evaluation of Flynpovi for FAP.

CPP-1X Eflornithine

CPP-1X (eflornithine) is being developed as a single agent tablet or high dose power sachet for several indications including prevention of gastric cancer and recent onset Type 1 diabetes. Preclinical studies as well as Phase 1 or Phase 2 investigator-initiated trials suggest that CPP-1X treatment may be well-tolerated and has potential activity.
