trial results of the FAVOUR trial are unfavorable, our clinical development plans for firmonertinib, which include conducting our global, pivotal Phase 3 FURVENT clinical trial in first-line non-squamous locally advanced or metastatic EGFRm NSCLC patients with exon 20 insertion mutations, may be adversely affected. In 2021, we licensed from Allist the right to develop and commercialize firmonertinib worldwide, with the exception of greater China, which includes mainland China, Hong Kong, Macau and Taiwan.
As one of the most prevalent cancers in the world, lung cancer imposes a significant global burden on human health, and EGFRm NSCLC represents a significant proportion of those affected. Despite progress in the therapeutic landscape for EGFRm NSCLC, many patients, particularly those with uncommon mutations, such as exon 20 insertions or PACC mutations, are underserved by existing treatments. In an interim data readout from the FAVOUR trial of firmonertinib in first-line patients with locally advanced or metastatic EGFRm NSCLC with exon 20 insertion mutations, 79% of patients (n=22 out of 28 patients) were observed to experience a reduction in tumor size of at least 30% from the baseline in a patient without evidence of progression as measured by blinded independent central review utilizing Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria, which measurement of reduction is the threshold in this trial for a partial response and for inclusion in determination of the overall response rate (ORR), which is the primary endpoint of this trial. In the same interim data readout, those 79% of patients were observed to experience a 15.2-month median duration of response (DOR). Interim results may not be indicative of final results; however, we believe these interim clinical results underscore firmonertinib’s potential in patients whose tumors contain an uncommon EGFRm.
In September 2024, we announced positive interim proof-of-concept data from the FURTHER trial of firmonertinib in first-line patients with locally advanced or metastatic EGFRm NSCLC with PACC mutations. In this interim readout, 64% of patients (n=14 out of 22 patients) were observed to experience a reduction in tumor size of at least 30% from the baseline in a patient without evidence of progression as measured by RECIST 1.1 criteria, which measurement of reduction is the threshold in this trial for a partial response and for inclusion in determination of the ORR, which is the primary endpoint of this trial. Median DOR had not yet been reached, with 90.9% (n=20/22) of patients with confirmed responses remaining on study. Interim results may not be indicative of final results; however, we believe these interim clinical results underscore firmonertinib’s potential in patients whose tumors contain an uncommon EGFRm.
We entered into the Global Technology Transfer and License Agreement (Allist License Agreement), pursuant to which, we have, among other things, secured an exclusive, royalty bearing and sublicensable license under certain intellectual property, including patents and know-how, owned or controlled by Allist to develop and commercialize any product containing firmonertinib or any of its salts or derivatives as an active ingredient of a product, which is led by a joint collaboration committee, comprising of representatives from both Allist and us. Under the Allist License Agreement, we are obligated to pay Allist milestone payments up to an aggregate of $765.0 million upon the achievement of certain development, regulatory and sales milestone events as set forth in the Allist License Agreement. During the nine months ended September 30, 2024 and 2023, no milestones were met or achieved. We are also obligated under the Allist License Agreement to pay Allist tiered royalties based on net sales of Licensed Products (as defined in the Allist License Agreement). See “Business — Licenses, Partnerships and Collaborations — Allist Agreements” in our Annual Report.
Since our inception in April 2021, we have devoted substantially all of our resources to organizing and staffing our company, acquiring the rights to develop firmonertinib, clinical development of firmonertinib, business planning, raising capital, identifying potential product candidates, enhancing our intellectual property portfolio and undertaking research and clinical and preclinical studies for our development programs. We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have funded our operations to date primarily through the private placement of convertible preferred stock and our initial public offering in January 2024.
On January 30, 2024, we completed the closing of our initial public offering of 9,722,222 shares of common stock at a price of $18.00 per share. Additionally, the underwriters exercised their option to purchase an additional 1,458,333 shares of common stock at a price of $18.00 per share. The shares of common stock began trading on the Nasdaq Global Market on January 26, 2024, under the symbol “AVBP”. We received net proceeds of $183.2 million, after deducting underwriting discounts and commissions and other offering expenses. In addition, as a result of the closing of our initial public offering, our convertible preferred stock converted into 19,567,306 shares of common stock in January 2024.
