Current report

In June 2025, we announced additional positive interim data from the FURTHER trial. In this interim readout, patients treated with 240 mg of firmonertinib were observed to experience 16.0 months median progression free survival and 14.6 months median duration of response. Further, 68.2% of patients treated in first-line at 240 mg and 43.5% of patients treated in first-line at 160 mg 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 determination of the ORR. In addition, 41% (n=7/17) of patients with brain metastases at baseline were observed to experience a confirmed response utilizing modified RECIST 1.1 and 53% (n=9/17) of first line patients with brain metastases at baseline 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. Firmonertinib was generally well-tolerated with interim safety results. Interim results may not be indicative of final results; however, we believe these interim clinical results continue to underscore firmonertinib’s potential in patients whose tumors contain an uncommon EGFRm.

Current report

In June 2025, we also announced plans to initiate ALPACCA (FURMO-006), the first randomized global Phase 3 study in first-line NSCLC in patients across PACC mutations. Enrollment of the first patient in the ALPACCA trial is expected in the second half of 2025.

Current report

General and administrative expenses were $11.4 million and $7.6 million for the six months ended June 30, 2025 and 2024, respectively. The increase of $3.8 million was due primarily to increases of $2.8 million in personnel-related costs and $1.0 million in accounting, legal, software, and other outside services.

Current report

On July 3, 2025, we closed an underwritten public offering in which we issued and sold an aggregate of 3,059,615 shares of our common stock, including the exercise in full of the underwriters’ option to purchase 576,923 additional shares of common stock, at a public offering price of $19.50 per share, and, in lieu of shares of common stock to certain investors, pre-funded warrants to purchase up to 1,363,469 shares of common stock at a public offering price of $19.4999 per pre-funded warrant, which represents the per share public offering price for the shares less the $0.0001 per share exercise price for each pre-funded warrant. The proceeds to us, net of underwriting discounts and commissions, were $81.1 million.

Current report

We will remain an emerging growth company and a smaller reporting company until December 31, 2025. As we transition out of emerging growth company status at the end of 2025, we will no longer be able to rely on exemptions provided by the JOBS Act, including without limitation, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act. Accordingly, we expect to incur significant additional legal, accounting and other expenses. Additionally, our management and other personnel will need to devote a substantial amount of time to these compliance initiatives.
Removed paragraphs (4)

Previous report

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the consummation ofour initial public offering, (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (Exchange Act), which would occur if, among other factors, the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year (subject to certain conditions) or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

Previous report

We are also a smaller reporting company as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Previous wording

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. Firmonertinib is an investigational, novel, epidermal growth factor receptor (EGFR) mutant-selective tyrosine kinase inhibitor (TKI) that we are developing for the treatment of NSCLC patients across a broader set of EGFRm than are currently served by approved EGFR TKIs. Firmonertinib is currently only approved and commercially distributed by Shanghai Allist Pharmaceuticals Co. Ltd. (Allist) in China as a first-line therapy to treat classical EGFRm NSCLC. The FDA has not approved firmonertinib for any use. We selected firmonertinib for global development against nonclassical, or uncommon, mutations based on preliminary reductions in tumor size observed in seven out of ten patients in first-line treatment with EGFR exon 20 insertion mutations in the ongoing Phase 1b clinical trial, the FAVOUR trial, conducted by Allist in China, and preclinical activity in EGFR P-loop and-alpha-c-helix compressing (PACC) mutations, each a subtype of uncommon mutation. In a subsequent 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

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.
