"We are increasingly encouraged by the strength and consistency of the tovecimig data as we deepen our analyses ahead of engaging FDA later this month, and we are pleased the full dataset has been selected for an oral presentation at ESMO (Free ESMO Whitepaper) in October. This enthusiasm is echoed in feedback we’ve received from leading BTC clinicians, which reinforces our belief that tovecimig will be an important treatment option for so many patients with BTC. In the coming weeks, we will be focused on engaging constructively with the FDA and incorporating any feedback as we advance towards a potential BLA filing," said Thomas Schuetz, MD, PhD, Chief Executive Officer and Vice Chairman of the Board of Directors.
"Building on our progress with tovecimig, we continued to advance our broader clinical pipeline this quarter. CTX-8371, our novel PD-1 x PD-L1 checkpoint inhibitor, continues to generate strong and durable clinical activity, some of which was presented at ASCO (Free ASCO Whitepaper), and we are well underway with cohort expansions. We also continue to enroll patients in the Phase 1 study of CTX-10726, our differentiated PD-1 x VEGF-A bispecific antibody. We look forward to sharing a series of meaningful updates in the remainder of 2026, including FDA feedback shortly, that demonstrate our continued execution across the portfolio and our ability to translate novel science into differentiated clinical products."
Pipeline Updates:
Tovecimig (DLL4 x VEGF-A bispecific antibody)
In April 2026, the Company announced positive data from its Phase 2/3 study of tovecimig, which it plans to include in a BLA submission later this year. The company expects to receive feedback from the FDA on these data in Q3 2026.
In the final data analysis, the overall response rate (ORR), the primary endpoint in the study, improved to 18.0% (20/111 patients) in the tovecimig combination arm from a previously reported 17.1%. One patient initially characterized as "Non-CR / Non-PD" due to target lesion characteristics was ultimately adjudicated by blinded independent central review (BICR) to be a partial response. With this change, the p-value improved to 0.0228 compared to paclitaxel alone (ORR of 5.3% in the paclitaxel arm).
The investigator sponsored trial (IST) of tovecimig in combination with the current first-line, standard-of-care regimen of gemcitabine, cisplatin, and durvalumab in patients with BTC (NCT06548412) is ongoing with expansion to additional sites expected.
Additional ISTs of tovecimig have been initiated, including a study of tovecimig plus FOLFIRI in patients with colorectal cancer in the second line setting (NCT07662031); and a novel-novel combination study of tovecimig plus CTX-471 in patients with glioblastoma in the second line setting (NCT07392957). The Company is evaluating additional studies for tovecimig in other indications, including both ISTs and Company-sponsored studies.
CTX-8371 (PD-1 x PD-L1 bispecific antibody)
Cohort expansions for CTX-8371 are actively enrolling patients with triple-negative breast cancer (n=28), non-small cell lung cancer (n=28), and Hodgkin lymphoma (n=12) in the post-checkpoint inhibitor setting. These indications were selected based on the deep and durable responses observed in these indications in the dose escalation portion of the study. Half of the patients with each tumor type will be dosed at 3.0 mg/kg and half will be dosed at 10.0 mg/kg.
Phase 1 data from the dose-escalation portion of the study was presented at ASCO (Free ASCO Whitepaper) 2026. Additional data from the cohort expansions are expected in Q4 2026.
CTX-10726 (PD-1 x VEGF-A bispecific antibody)
The first patients have been dosed in the Phase 1 study, and the study is actively enrolling, with initial clinical data expected in Q4 2026.
The Phase 1 multiple ascending dose-escalation study will include four doses (0.3, 1.0, 3.0, and 10.0 mg/kg) in a 3+3 dose-escalation design. The multi-center study will enroll patients with a prioritized set of solid tumor indications, including patients with locally advanced, unresectable or metastatic renal cell carcinoma, gastroesophageal cancer, hepatocellular carcinoma, and endometrial cancer, in whom standard of care therapies have failed.
CTX-10726 is a tetravalent PD-1 x VEGF-A bispecific antibody discovered and engineered by the Company. CTX-10726 exhibits more potent PD-1 blockade compared with data reported for other drugs in the class.
CTX-471 (CD137 or 4-1BB agonist antibody)
The Phase 2 trial of CTX-471 in patients with tumors expressing NCAM (CD56) will be initiated in Q3 2026.
Financial Results
Net loss for the quarter ended June 30, 2026, was $25.2 million or $0.13 per common share, compared to $19.9 million or $0.14 per common share for the same period in 2025.

Research and Development (R&D) Expenses
R&D expenses were $19.6 million for the quarter ended June 30, 2026, as compared to $16.4 million for the same period in 2025, an increase of $3.2 million or 19%. This was primarily driven by an increase of $2.6 million of expenses related to tovecimig. R&D expenses were $33.0 million for the six months ended June 30, 2026, as compared to $29.5 million for the same period in 2025, an increase of $3.5 million or 12%. This was primarily driven by an increase of $2.5M of stock compensation expense and $1.3M of manufacturing expense.
General and Administrative (G&A) Expenses
G&A expenses were $7.4 million for the quarter ended June 30, 2026, as compared to $4.7 million for the same period in 2025, an increase of $2.7 million or 59%. This was primarily driven by an increase of $1.4 million of pre-commercialization expenses and $0.8 million of higher stock compensation expense.
