Trial Summary

Will I have to stop taking my current medications?

The trial requires that you stop taking any anti-tumor drugs, investigational drugs, and certain other medications like strong CYP3A4 inhibitors or inducers, and OATP1B inhibitors before starting the study. You should discuss your current medications with the study team to see if they fall into these categories.

What data supports the effectiveness of the drug ENV-501 for breast cancer?

The combination of bevacizumab with taxane drugs has shown to improve progression-free survival and objective remission in certain types of breast cancer, although it did not extend overall survival. This suggests that similar treatments might help control the disease for a period of time.12345

What is the purpose of this trial?

This study is a Phase 1/2, first-in-human, open-label, clinical trial to assess the safety, tolerability, pharmacokinetics and preliminary efficacy of ENV-501 in patients with advanced-stage, relapsed and/or refractory human epidermal growth factor receptor 3 (HER3)-expressing solid tumors. The study consists of 2 phases: a dose escalation phase (Phase 1) and a dose expansion phase (Phase 2).The primary objectives of Phase 1 are to characterize the overall safety and tolerability profile of increasing doses of ENV-501 in patients with advanced-stage solid tumors and identify the recommended Phase 2 dose (RP2D) of ENV-501. During Phase 1, successive cohorts of patients will receive escalating doses of ENV-501. The results of the dose escalation will determine the RP2D and dosing schedule of ENV-501 to be administered in the Phase 2 part of the study. The primary objective of Phase 2 is to evaluate the preliminary clinical efficacy of ENV-501 in dose expansion cohorts.

Interventions

  • ENV-501
Trial Overview ENV-501 is being tested in this two-phase clinical trial. Phase 1 will find the safest dose by gradually increasing it among groups of patients. Phase 2 will use this established dose to assess how effective ENV-501 is against these cancers.

Findings from Research

Nurse practitioners are crucial in managing breast cancer, particularly in prevention, early detection, and treatment, emphasizing the importance of health assessments as part of their core competencies.
The review of five case studies shows that eribulin mesylate can be an effective treatment option for women with metastatic breast cancer who have previously undergone at least two chemotherapy regimens, highlighting its role in managing adverse events and improving therapeutic outcomes.
Oncology nursing support for safe and effective use of eribulin in metastatic breast cancer.Donovan, D., Urquhart, L., Hopkins, U., et al.[2021]
In a study of 1206 women with HER2-negative operable breast cancer, adding bevacizumab (bev) to neoadjuvant chemotherapy resulted in a higher rate of early surgical complications (25.4% vs. 18.9%), although most complications were mild (grade 1-2).
While bev increased the incidence of long-term noninfectious wound complications (11.8% vs. 5.1%), the occurrence of serious complications requiring surgical intervention was low, suggesting that bev can be used safely in the perioperative setting with appropriate precautions.
