ClinConnect Summary

This clinical trial is studying a new treatment called ProAgio in combination with a standard chemotherapy drug called Gemcitabine for patients with metastatic triple negative breast cancer. Triple negative breast cancer is a type of cancer that doesn’t respond to hormones or the HER2 protein, making it more challenging to treat. The trial is looking to see if this new combination can be safe and effective for patients who have already received other treatments for their cancer.

To participate, patients need to be at least 18 years old and have been diagnosed with metastatic triple negative breast cancer. They should have already tried at least two other treatments for their cancer. Participants will undergo some tests to ensure their overall health is adequate before starting the study. During the trial, participants will receive the study drugs and will be monitored closely for any side effects or changes in their condition. It’s important for those interested to know that women who are pregnant or breastfeeding cannot take part in this study due to potential risks to the baby. Overall, this trial aims to explore new treatment options for a difficult-to-treat type of breast cancer.

Eligibility criteria

• Inclusion Criteria:
• • Adult participants, ≥ 18 years of age, with histologically or cytologically confirmed metastatic breast cancer that is estrogen receptor (ER) negative (less than 10%), progesterone receptor (PR) negative (less than 10%), and HER2 negative/unamplified as per ASCO/CAP guidelines (Wolff et al., 2018). If ER/PR less than 10%, prior endocrine therapy is permitted, and the participant is not considered appropriate for hormone based therapy. Participants must agree to provide archival tumor material from metastatic site (most recent archival tumor tissue immediately prior to enrollment is strongly preferred) and must agree to undergo research tumor biopsy before treatment and during cycle 2 at the same site of metastatic disease, if presence of easily accessible lesion, at the discretion of the treating physician.
• • Participants must have received at least two lines of prior systemic treatment for advanced disease. If participants received systemic therapy in the operable setting and the tumor progressed within 12 months of the receipt of the last dose of systemic therapy, this will be considered one line of prior systemic therapy for advance disease. Participants must be more than 14 days removed from most recent standard of care or experimental drug treatment for their tumor.
• • ECOG performance status ≤2
• * Participants must have adequate organ and marrow function as defined below:
• • Absolute neutrophil count ≥1,500/mcL
• • Hemoglobin ≥9 g/ dL (recent transfusion allowed)
• • Platelets ≥100,000/mcL
• • AST(SGOT)/ALT(SGPT) ≤3 x ULN. AST and ALT (up to 5x ULN is permitted for participants with liver metastases)
• • Total bilirubin ≤1.5 x institutional ULN
• • Creatinine clearance ≥60 mL/min (measured using Cockcroft- Gault equation or the estimated glomerular filtration rate)
• • Participants with CNS metastases must be treated and/or stable (no progression for at least 4 weeks after local prior therapy as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period). Those with symptoms suggestive of possible CNS metastases (such as new headaches) must undergo brain MRI as part of screening.
• • Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
• • The effects of ProAgio on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for the 6 months following the last dosing of study drug. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
• • During dose escalation, participants with bone only and/or non-measurable disease are eligible. During dose expansion, only participants with measurable disease are eligible.
• • Ability of subject to understand and the willingness to sign a written informed consent document.
• Exclusion Criteria:
• • Participants who have had prior treatment with gemcitabine in the metastatic setting.
• • Platelet transfusion within 7 days prior to treatment start.
• • Participants with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better. Patients with history of known congestive heart failure (left ventricular ejection fraction (LVEF) \<50%) must have documented LVEF \>50% within 12 months of study enrollment.
• • Prolonged QTc interval \>480 msec on screening EKG
• • Participants with known diagnosis of a chronic neurologic disorders (such as multiple sclerosis, Huntington's disease, Parkinson's disease, or uncontrolled epilepsy) which causes motor disturbance, visual disturbance, or seizure and could confound assessment of neurologic toxicity caused by the study drug.
• • Pregnant or nursing women are excluded from this study because ProAgio is an agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with ProAgio, breastfeeding should be discontinued if the mother is treated with ProAgio.
• • Participants who have undergone a major surgical procedure (within \< 28 days) are excluded.
• • Participants with uncontrolled bleeding episodes \<28 days prior to enrollment are excluded.
