Study Endpoints

Primary Endpoints

ORR, Objective Response Rate
Approximately 7.5 months following the last patient enrolled

Percentage of patients with a confirmed CR or PR relative to the total number of patients.

Progression-free survival (PFS)
The primary analysis of Progression-free survival (PFS) based on investigator assessment will occur when PFS maturity is observed at approximately 34 months after the first patient begin study treatment

Progression-free survival (PFS) using Investigator assessment as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). Progression-free survival (PFS) is defined as the time from beginning of study treatment until the date of objective disease progression or death (by any cause in the absence of progression), regardless of whether the patient withdraws from randomized therapy or receives another anti-cancer therapy prior to progression. Patients who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment from their last evaluable Response Evaluation Criteria in Solid Tumors (RECIST) assessment.

Stage 1: Number of incidence and severity of adverse events (AEs) as a measure of safety and tolerability of Furmonertinib
Up to 36 months after first dose
Stage 2: Overall Response Rate (ORR)
Up to 36 months after first dose

Secondary Endpoints

DOR, Duration of response
Approximately 7.5 months following the last patient enrolled
DCR, Disease control rate

Frequently asked questions about Furmonertinib

What is Furmonertinib used for?

Furmonertinib is an investigational small molecule being developed for non-small cell lung cancer (NSCLC), including metastatic and advanced forms of the disease. It is studied in patients with EGFR mutations, such as exon 20 insertions and uncommon mutations, and is currently in clinical trials.

What does Furmonertinib target?

Furmonertinib targets the epidermal growth factor receptor (EGFR), an inhibitor of this receptor. It is being studied in non-small cell lung cancer patients with activating EGFR mutations, including exon 20 insertions and uncommon mutations like G719X and S768I.

Who makes Furmonertinib?

Furmonertinib is being developed by ArriVent BioPharma, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol AVBP. The company is conducting clinical trials to evaluate the drug in patients with non-small cell lung cancer.

What phase is Furmonertinib in?

Furmonertinib is in Phase 2 clinical development. It is an investigational drug, not yet approved by regulatory authorities. The ongoing trials include a Phase 2 study in NSCLC with EGFR exon 20 insertions, and a Phase 3 study comparing it to chemotherapy.

What clinical trials is Furmonertinib in?

Furmonertinib is being studied in several clinical trials, including NCT05466149 (Phase 2 in NSCLC with EGFR exon 20 insertion), NCT05607550 (Phase 3 FURVENT trial comparing to chemotherapy), NCT04858958 (Phase 1 in NSCLC with exon 20 insertion), and NCT05364073 (Phase 1 in advanced NSCLC with EGFR or HER2 mutations).

Is Furmonertinib the same as furmonertinib 160mg or 240mg?

Yes, Furmonertinib is the same drug as furmonertinib 160mg and furmonertinib 240 mg oral daily. These names refer to the same investigational medication, which is being studied in various dosages for the treatment of non-small cell lung cancer.
