Brief Summary

The purpose of this study is to determine safety and tolerability of AVB-500 when given in combination with paclitaxel in patients with recurrent high-grade uterine cancer.

Conditions

Recurrent High Grade Uterine Cancer

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Paclitaxel + AVB-500

Patients will receive up to 9 21-day cycles of paclitaxel + AVB-500. Patients will receive AVB-500 via intravenous (IV) infusion at the assigned dose level on days 1, 8, and 15 of each cycle. Patients will receive IV paclitaxel at a dose of 175 mg/m\^2 on day 1 of each cycle. After 3 cycles, patients will be assessed for disease response. Patients who have progression will not continue on treatment. Patients who have a partial response or stable disease will continue on treatment for another 3 cycles of paclitaxel + AVB-500 at the assigned dose. Patients will be assessed for response again at the end of 6 cycles and may continue on treatment if they have partial response (PR) or stable disease (SD). Up to 9 cycles of treatment with paclitaxel + AVB-500 may be given. At the end of the 9 cycles, patients with a SD or PR can continue on maintenance AVB-500 until progression. Patients with complete response will continue single agent AVB-500 as maintenance therapy until progression.

Eligibility Criteria

Inclusion Criteria

• Diagnosis of recurrent, FIGO grade 3 endometrioid, serous, or mixed high grade uterine or endometrial cancer. Patients must have experienced either prior progression on a platinum-based therapy or intolerance to platinum. Patients with dMMR or MSI-H tumors or targetable HER2 alterations are required to have received prior therapy with appropriate targeted agents.
• Patients must have disease that cannot be managed by local therapy.
• Measurable disease by RECIST 1.1
• Women or transgender men with a uterus who are at least 18 years of age.
• ECOG performance status ≤ 2
• Normal bone marrow and organ function as defined below:

• Absolute neutrophil count ≥ 1.5 K/cumm
• Platelets ≥ 100 K/cumm
• Hemoglobin ≥ 9.0 g/dL
• Total bilirubin ≤ 1.5 x IULN
• AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN (unless liver metastases are present in which case AST/ALT must be ≤ 5.0 x IULN)
• Serum creatinine < 2.0 mg/dL or < 177 µmol/L OR calculated or measured creatinine clearance ≥ 40 mL/min (using Cockcroft-Gault equation)
• INR ≤ 1.5 x IULN
• aPTT ≤ 1.5 x IULN
• The effects of AVB-500 on the developing human fetus are unknown. For this reason and because chemotherapeutic agents are known to be teratogenic, patients of childbearing potential must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation. Should a patient become pregnant or suspect pregnancy while participating in this study, the treating physician must be informed immediately.
• Subjects who have received prior treatment with trastuzumab, pembrolizumab, or dostarlimab can enroll in the study.
• Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria

• Any prior treatment with AVB-500
• A history of other malignancy with the exception of malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence of disease.
• Currently receiving any other (non-study) cytotoxic chemotherapy, radiation, targeted treatment, or immunotherapy within 4 weeks prior of start of study treatment.
• Currently receiving any other investigational agents or has received an investigational agent within 4 weeks of start of study treatment.
• Known brain metastases. Patients with known brain metastases must be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
• A history of allergic reactions attributed to compounds of similar chemical or biologic composition to AVB-500 or other agents used in the study.
• Abnormal gastrointestinal function, defined as Grade >2 diarrhea, constipation, nausea, vomiting, or abdominal pain. This includes GI obstruction or bleeding or signs/symptoms thereof within 3 months of study enrollment. Patients with a history of abdominal fistula will be considered eligible if the fistula was surgically repaired or has healed, there has been no evidence of fistula for at least 6 months, and patient is deemed to be at low risk of recurrent fistula.
• Significant cardiac disease history including:

• Clinically significant atrial or ventricular arrhythmias requiring treatment
• Medically controlled congestive heart failure
• Significant angina or clinically and/or electrocardiographically documented myocardial infarction within the past year
• Clinically significant valvular disease
• Non-healing wound, ulcer, or bone fracture.
• Known active hepatitis; ongoing systemic bacterial, fungal, or viral infection.
• History or evidence upon physical examination of CNS disease, including primary brain tumor, seizures not controlled with standard medical therapy, or history of CVA, TIA, or subarachnoid hemorrhage within 6 months of the first date of treatment on this study.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia.
• History of major surgical procedure within 14 days prior to start of study treatment.
• Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
• Patients with HIV are eligible unless their CD4+ T-cell counts are < 350 cells/mcL or they have a history of AIDS-defining opportunistic infection within the 12 months prior to registration. Concurrent treatment with effective ART according to DHHS treatment guidelines is recommended. Recommend exclusion of specific ART agents based on predicted drug-drug interactions (i.e. for sensitive CYP3A4 substrates, concurrent strong CYP3A4 inhibitors (ritonavir and cobicistat) or inducers (efavirenz) should be contraindicated).

• Minimum Eligible Age: 18 Years
