Chugai reported increased revenue and operating profit year-on-year for the third quarter (Core-basis).

Regarding revenue, domestic sales increased by 3.6%. In the oncology field, sales increased by 0.2%. While our mainstay product Avastin was affected by NHI drug price revisions and generics, this was offset by steady growth of new products Phesgo, Lunsumio, and our mainstay product Polivy. In the specialty field, sales increased by 7.7%, driven by steady performance of mainstay products Vabysmo, Hemlibra, and Enspryng, along with successful market penetration of the new product PiaSky. Overseas sales increased by 7.7%, driven by a substantial increase in exports of Actemra to Roche. Other revenue decreased by 0.9%, despite the increase in income related to Hemlibra, mainly due to a decrease in one-time income.

Cost to sales ratio increased by 0.6 percentage points year-on-year to 33.1%, mainly due to changes in the product mix. Research and development expenses increased by 0.7% due to investments into drug discovery and early development, and increases associated with the progress of development projects, while selling, general and administrative expenses decreased by 4.3% mainly driven by various expenses. Other operating income (expense) resulted in income of ¥0.4 billion. As a result, Core operating profit was ¥450.5 billion (+5.6%) with a Core operating profit margin (to revenue) of 49.4%.

Chugai made good progress in both in-house products and products in-licensed from Roche.

For in-house products, PiaSky was launched in Taiwan as the first subcutaneous formulation for paroxysmal nocturnal hemoglobinuria. Enspryng has obtained results from Phase III clinical trials for thyroid eye disease, and will be discussed with health authorities. For Chugai originated project, Orforglipron, an oral GLP-1 receptor agonist out-licensed to Eli Lilly, met primary endpoints in multiple Phase III clinical trials for obesity and type 2 diabetes.

For products in-licensed from Roche, Tecentriq has obtained approval for an expanded indication for relapsed or refractory extranodal NK/T-cell lymphoma, nasal type. Avastin has been filed for an expanded indication for neurofibromatosis type II. Glofitamab has initiated Phase II clinical trials in Japan for both relapsed or refractory diffuse large B-cell lymphoma and relapsed or refractory mantle cell lymphoma. Additionally, afimkibart has initiated Phase III clinical trial for Crohn’s disease, and divarasib initiated Phase Ib/II clinical trial for non-small cell lung cancer (first-line treatment). Furthermore, Chugai has in-licensed CT-388, a long-acting GLP-1/GIP receptor agonist, from Roche.

On October 24, 2025 Arvinas, Inc. (Nasdaq: ARVN), a clinical-stage biotechnology company creating a new class of drugs based on targeted protein degradation, reported preclinical data for ARV-806, a PROTAC KRAS G12D degrader, at the 2025 AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in Boston, Massachusetts. The ARV-806 data presented show a differentiated profile based on degradation potency, antiproliferative activity, and induction of cancer cell death. ARV-806 is designed to target both the ON and OFF forms of KRAS G12D, which is the most common mutation of the KRAS protein. ARV-806 has the potential to address high unmet need in solid tumors, such as pancreatic, colorectal and non-small cell lung cancer.

"These data suggest the potential of targeted protein degradation to overcome historical limitations in addressing undruggable KRAS mutations," said Angela Cacace, Ph.D., Chief Scientific Officer of Arvinas. "ARV-806’s ability to eliminate both ON and OFF forms of KRAS G12D, combined with its potency and durability shown in preclinical models, supports our confidence in its clinical potential to deliver meaningful benefit for patients with KRAS G12D-mutated cancers."

Key highlights from the presentation include:

In vitro, ARV-806 degraded KRAS G12D with picomolar potency across pancreatic, colorectal, and lung cancer cell lines but did not induce degradation of wild-type and other mutant RAS isoforms.
ARV-806 is differentiated from other KRAS G12D targeting agents in development and has potential to be a best-in-class therapy for KRAS G12D mutated cancers due to:
Catalytic activity, which allows it to overcome upregulation, a common mechanism of resistance to inhibitor treatment
Compared with clinical-stage KRAS G12D ON and OFF inhibitors and another clinical-stage G12D degrader, ARV-806 demonstrated:
>25-fold greater potency in reducing cancer cell proliferation,
>40-fold higher potency in degrading KRAS G12D protein (versus the comparable clinical-stage G12D degrader), and
>10-fold lower concentrations required to induce pro-apoptotic BIM expression.
Following a single intravenous dose in a colorectal tumor xenograft model, ARV-806 degraded >90% of KRAS G12D for seven days, with parallel suppression of c-MYC (a key driver of cancer cell proliferation) and induction of BIM (Bcl-2-interacting mediator of cell death, a pro-apoptotic factor) for ≥5 days.
ARV-806 demonstrated robust efficacy responses at low doses in tumor models including: ≥30% tumor volume reductions in pancreatic and colorectal cell line-derived xenograft (CDX) models and a patient-derived xenograft (PDX) model of lung cancer.

These data demonstrate sustained pharmacodynamic activity consistent with long-lasting target degradation, which we believe supports intermittent clinical dosing. Arvinas is currently evaluating ARV-806 in a Phase 1 clinical trial in patients with KRAS G12D–mutated advanced solid tumors (NCT07023731).

Also shown in the poster, orally bioavailable pan-KRAS degraders have been identified that potently degrade multiple variants of KRAS and spare other RAS isoforms. A tool pan-KRAS PROTAC demonstrated robust single-agent activity and superior combination efficacy with immune checkpoint blockade compared with a pan-RAS ON inhibitor (7 complete responses compared with 2 complete responses).

About ARV-806
ARV‑806 is a novel, investigational PROTAC degrader designed to selectively target and degrade mutant Kirsten rat sarcoma (KRAS) G12D which is the most common mutation of the KRAS protein. Therefore, ARV-806 has the potential to address high unmet need in solid tumors, such as pancreatic, colorectal and lung cancer. ARV‑806 is currently being evaluated in a Phase 1 clinical trial in patients with advanced solid tumors harboring KRAS G12D mutations.

A poster titled Early safety and efficacy of APR-1051, a novel WEE1 inhibitor, in patients with cancer-associated gene alterations: Updated data from ACESOT-1051 Phase 1 trial will be presented today at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper). The poster, to be presented by Drs. Timothy Yap MBBS, PhD, FRCP, University of Texas MD Anderson Cancer Center and lead investigator of the study, and Philippe Pultar, MD, Senior Medical Advisor at Aprea, summarizes preliminary results from the trial with a cutoff date of September 17, 2025. A copy of the poster will be available on Investors page of the Aprea corporate website under "Investor Presentations & Resources."

"We continue to be encouraged by these early clinical findings, which demonstrate signals of anti-tumor activity with APR-1051 in a heavily pre-treated patient population," said Dr. Pultar. "We believe the observation of disease control in tumors harboring FBXW7, CCNE1, and KRAS mutations align with our mechanistic understanding of WEE1 inhibition and reinforces the scientific rationale for APR-1051 development. We believe these promising data provide an important foundation as we continue with dose escalation in the ongoing study and we look forward to providing further updates as we advance to higher dose level in the ongoing study."

ACESOT-1051 Clinical Update (data cutoff October 19, 2025)

The primary objective of the trial is to characterize the safety profile, dose-limiting toxicity, maximum tolerated dose or maximum administered dose, and recommended Phase 2 dose of APR-1051. Secondary objectives are to 1) to characterize the pharmacokinetics of APR-1051 and the major metabolites and active metabolites of APR-1051, and 2) to assess preliminary efficacy of APR-1051
Results from Dose Level 6 (100 mg), show 3 out of 4 patients achieved stable disease, per RECIST v1.1 in heavily pretreated gastrointestinal and gynecologic malignancies
Disease stabilization was observed in patients with FBXW7, CCNE1, and KRASG12V + TP53 alterations
Favorable tolerability: No dose limiting toxicities (DLTs) or unexpected safety issues reported to date.
Following successful clearance of the 100 mg cohort, dose escalation has progressed to Dose Level 7 (150 mg)
For more information on ACESOT-1051, refer to ClinicalTrials.gov NCT06260514.

CDR404 is an antibody-based TCE designed to target intracellular tumor antigens presented on HLA molecules. It engages MAGE-A4 peptides displayed by HLA-A*02:01 on cancer cells and redirects CD3+ T cells for targeted tumor cell killing. The ongoing Phase 1 CDR404 trial (NCT06402201) is being conducted at leading cancer centers across the United States and Europe. Unlike conventional approaches utilizing T cell receptors, the proprietary M-gager platform leverages antibody-derived binding domains that combine exceptional specificity with strong potency, excellent developability and ease of manufacturing.

At initial dose levels of 100–200 μg, CDR404 triggered the full cascade of immune activation associated with effective TCE therapy, including CD8+ T cell activation and expansion, reprogramming to a memory phenotype and recruitment of lymphocytes into tumors. Notably, repeated dosing did not induce PD-1–mediated T cell exhaustion, suggesting sustained biological activity. In one patient, a transient tumor flare followed by stabilization was observed, which is consistent with tumor infiltration by cytotoxic T cells.

"These early data demonstrate that our M-gager platform can extend the precision and power of antibody-based T cell engagers to intracellular antigens, an area long thought to be accessible only to TCR-based modalities," said Christian Leisner, PhD, Chief Executive Officer of CDR-Life. "Seeing all four pharmacodynamic hallmarks of activity in patients even at low doses underscores the potential of this approach to redefine how we target solid tumors."

The study’s first-in-human dose was guided by quantitative systems pharmacology modeling, enabling detection of pharmacodynamic effects more quickly than traditional approaches. Based on these encouraging signals, the trial will begin to focus on patients with MAGE-A4–positive ovarian cancers, a population with high unmet need.

Additional analyses, including integrated pharmacokinetic-pharmacodynamic and circulating tumor DNA (ctDNA) data, are ongoing.
