ClinConnect Summary

This clinical trial is studying a new oral medication called AVZO-021, which is designed to treat patients with advanced solid tumors. The main goals of the study are to understand how safe the medication is, how well it is tolerated, how it works in the body, and whether it can help shrink tumors. The trial is currently looking for participants, including men and women aged 18 and older, who have certain types of cancer that are no longer responding to standard treatments. For example, patients with specific types of breast cancer or certain advanced tumors may be eligible.

If you decide to participate, you will receive AVZO-021 and be monitored closely for any side effects and how well the medication is working. It's important to note that participants should not have had other cancer treatments recently, should be able to take pills, and must have certain health criteria met, such as good organ function. This trial is an important step in finding new therapies for patients who have limited options due to advanced cancer.

Eligibility criteria

• Key Inclusion Criteria:
• • 1. Male or female aged ≥18 years old at screening with Eastern Cooperative Oncology Group (ECOG) 0-1.
• 2. Disease-related inclusion criteria by study phase and part:
• • i) Phase 1a Monotherapy Dose Escalation: Patients with locally advanced or metastatic HR+/HER2- breast cancer, CCNE1-amplified tumors that are either epithelial ovarian cancer, primary peritoneal cancer, fallopian tube cancer, endometrial cancer or TNBC, with no other oncogenic driver mutations that are treatable and standard therapies are no longer effective, appropriate, or safe in the opinion of the investigator and medical monitor. Patients with any additional tumor type with CCNE1 amplification can be enrolled only if clinical data is supportive and approved by medical monitor (Cohort 1A).
• • ii) Phase 1b Combination Dose Escalation: histologically or cytologically confirmed diagnosis of locally advanced or metastatic HR+ HER2- (HER2-low may be allowed if failed standard of care therapy) breast cancer, who have been previously treated with inhibitor of CDK4/6 and endocrine therapy(Cohorts 1B1, 1B2, 1B3, 1B4, and 1B5); or histologically or cytologically confirmed diagnosis of CCNE1- amplified, locally advanced or metastatic, platinum-refractory or platinum-resistant EOC, primary peritoneal, or fallopian tube cancer (Cohort 1C).
• • iii) Phase 2a Monotherapy dose expansion: Histologically or cytologically confirmed diagnosis of locally advanced or metastatic CCNE1 amplified epithelial ovarian cancer, primary peritoneal cancer, fallopian tube cancer, endometrial cancer or TNBC, with no other oncogenic driver mutations that are treatable and standard therapies are no longer effective, appropriate, or safe in the opinion of the investigator and medical monitor (Cohort 2A).
• • iv) Phase 2b Combination dose expansion: Histologically or cytologically confirmed diagnosis of locally advanced or metastatic HR+/HER2- (HER2-low may be allowed if failed standard of care therapy) breast cancer who have been previously treated with no more than 1 prior CDK4/6 inhibitor and endocrine therapy (Cohorts 2B1, 2B2, 2B3, 2B4, and 2B5); or Histologically or cytologically confirmed diagnosis of locally advanced or metastatic, CCNE1-amplified, platinum-refractory or platinum-resistant EOC, primary peritoneal cancer, or fallopian tube cancer (Cohort 2C).
• • 3. No more than 2 prior cytotoxic chemotherapy regimens for locally advanced/metastatic disease (excepting patients treated with an antibody-drug conjugate, with ovarian cancer if there disease is platinum resistant or refractory, having progressed beyond all SOC care; and patients who have received prior chemotherapy in the adjuvant or neoadjuvant setting \>12 months prior to starting AVZO-021 treatment).
• • 4. Measurable disease as determined by RECIST version 1.1.
• • 5. Adequate bone marrow and organ function.
• • 6. Ability to swallow capsules or tablets.
• Key Exclusion Criteria:
• • 1. Received an investigational agent or anticancer therapy within 2 weeks, or 5 half-lives of the drug, whichever is shorter, prior to planned start of AVZO-021.
• • 2. Received any CDK2 inhibitor, protein kinase membrane associated tyrosine/threonine 1 (PKMYT1) inhibitor, or WEE1 inhibitor anticancer therapy. For cohort B5, prior therapy with topoisomerase inhibitors is not permitted.
• • 3. Undergone major surgery within 4 weeks prior to planned start of AVZO-021.
• • 4. Received radiotherapy for palliation within 7 days of the first dose of study treatment, unless specified otherwise in the protocol.
• • 5. Active CNS metastases or confirmed leptomeningeal disease are not eligible.
• • 6. Unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 Grade \>1 at the time of starting study treatment.
• • 7. Clinically unstable cardiac function as described in the protocol.
• • 8. Any active or chronic infection/disease that compromises the immune system.
• • 9. Current treatment with strong or moderate cytochrome P450 (CYP)3A4 inhibitors or inducers.
• • 10. Active second malignancy unless in remission with life expectancy \> 2 years and with documented sponsor approval.
• • 11. Pregnancy, lactation, or plans to breastfeed during the study or within 6 months of the last dose of study intervention.
