On September 24, 2025 Artios Pharma Limited ("Artios"), a biopharmaceutical company committed to realizing the therapeutic power of targeting the DNA damage response ("DDR") in cancer, reported that the U.S. Food and Drug Administration (FDA) granted Fast Track designation to its ATR inhibitor, alnodesertib, in combination with a low dose of chemotherapeutic agent irinotecan, for the treatment of adult patients with ATM-negative metastatic colorectal cancer (mCRC) in the third-line setting (Press release, Artios Pharma, SEP 24, 2025, View Source [SID1234656187]).

"The Fast Track designation for alnodesertib underscores its first-in-class potential for third-line mCRC patients with ATM-negative tumors," said Mike Andriole, Chief Executive Officer of Artios. "Approximately 3,000 patients with ATM-negative third-line mCRC succumb to this disease annually in the United States, with no treatment options that specifically address this protein deficiency. Alnodesertib has the potential to be the first treatment specifically for this invariably lethal disease. Additionally, we are encouraged by the durable responses this program has demonstrated across other tumor types, highlighting its ability to target replication stress across a range of solid tumors."

The designation is supported by encouraging results from the ongoing STELLA Phase 1/2a study, which is evaluating alnodesertib in combination with a low dose of irinotecan. Beyond third-line mCRC, clinical responses were observed in seven additional solid tumor types with ATM deficiency. The combination of alnodesertib plus low-dose irinotecan has a favorable safety profile to date, has been well tolerated, and has been shown to be suitable for long-term dosing.

"Patients with third-line colorectal cancer face a dismal prognosis, with current standards of care for third-line mCRC delivering response rates in the single digits. In our studies to date, alnodesertib has demonstrated compelling clinical activity in ATM-negative patients with mCRC as well as in other heavily pretreated cancer types with high endogenous replication stress," said Ian Smith, Chief Medical Officer of Artios. "These results, together with activity across other solid tumors, highlight alnodesertib’s potential to deliver meaningful benefit where treatment options are limited. The FDA’s Fast Track designation recognizes both the strength of our early clinical data and the urgent need for new therapies, while also providing the opportunity for enhanced interactions with the Agency."

The FDA’s Fast Track program is designed to facilitate the development and expedite the review of investigational drugs that demonstrate the potential to address unmet medical needs in serious or life-threatening conditions. Product candidates with Fast Track designation are eligible for priority review and accelerated approval if relevant criteria are met. The Fast Track designation for alnodesertib was granted based on early Phase 1/2 clinical studies that are currently ongoing in the United States. The designation will enable Artios to interact early and more frequently with the FDA to discuss alnodesertib’s development path.

About Alnodesertib

Alnodesertib, formerly known as ART0380, is a potential first-in-class, orally administered, selective small molecule inhibitor of ataxia-telangiectasia and Rad3-related protein (ATR). Artios’ differentiated approach combines alnodesertib with a low dose of the chemotherapy irinotecan, targeting cancers with high endogenous replication stress, such as those with ATM protein deficiency.

On September 23, 2025 Taiho Pharmaceutical Co., Ltd. (hereinafter "Taiho Pharmaceutical"), reported a collaboration agreement with Guardant Health, Inc. (hereinafter "Guardant Health") to discover new biomarker signatures by leveraging Guardant Health’s "GuardantINFORMTM" platform for multimodal analysis of real-world data (Press release, Taiho, SEP 24, 2025, View Source [SID1234656173]).

This collaboration aims to discover new biomarker signatures with clinical and biological significance for addressing unmet needs in early-stage recurrent cancer, where the presence of microscopic cancer cells remaining in the body after surgery is a cause of recurrence. This collaboration leverages unique multimodal and longitudinal cohorts within GuardantINFORM, including those with minimal residual disease (MRD) testing.

This initiative is expected to support the development of treatments for patients at high risk of recurrence and lead to new and clinically relevant approaches enabling medical interventions at an early stage of cancer. The collaboration has an overarching goal of driving significant progress in overcoming cancer.

Taiho Pharmaceutical has a strong track record of developing multiple investigational and approved drugs in Japan, the US, and Europe by utilizing its proprietary "Cysteinomix drug discovery" which enables the creation of drugs that bind specifically and strongly to drug targets. By further analyzing the novel gene signatures identified through this collaboration and integrating these insights with the Cysteinomix drug discovery platform, we anticipate substantial potential to develop precise and effective treatment approaches for new drug targets that were previously difficult to discover.

Takeshi Sagara, Taiho Pharmaceutical’s Executive Director, Clinical Development and Medical Affairs, Discovery & Preclinical Research, said, "We believe that future anticancer drug discovery focusing on research and development not only for advanced cancer but also for early-stage recurrent cancer, with an eye on the patient’s journey, will lead to long-term survival and ultimately the overcoming of cancer. Through our collaboration with Guardant Health, we aim to identify and develop biomarker signatures, that arise in early-stage recurrence and contribute to the creation of next-generation treatment methods."

About Cysteinomix Drug Discovery
Cysteinomix drug discovery is Taiho Pharmaceutical’s original drug discovery technology designed to continuously generate covalent drugs targeting a variety of proteins that contain cysteine. Covalent drugs are pharmaceuticals that irreversibly control the function of target proteins by forming covalent bonds with them. These drugs consist of a ligand that binds to a protein pocket and a reactive group that forms a covalent bond with a specific amino acid. The Cysteinomix drug discovery platform is composed of a target protein database, a covalent compound library, and various compound evaluation systems, among other components. To date, this platform has successfully led to the creation of several pipelines.

Phase I dose-escalation study shows positive potential

In the completed Phase I study with escalation and supplemental enrollment across six dose groups (1-45 mg/kg), CS2009 demonstrated:

1. Excellent safety : No dose-limiting toxicity (DLT) was observed in all evaluated dose groups , and dozens of patients had good overall tolerance.

2. Pharmacokinetics/pharmacodynamics (PK/PD) are in line with expectations :

(1) PK characteristics support a three-week dosing schedule, with no accumulation after multiple dosing;

(2) PD data also confirmed that CS2009 achieved saturated receptor occupancy by blocking PD-1/CTLA-4, triggering T cell activation and proliferation, and had a strong and lasting neutralizing effect on VEGFA.

3. Broad and deepening anti-tumor activity :

(1) Significant anti-tumor activity was observed at all doses, and the activity continued to increase with prolonged follow-up ;

(2) Anti-tumor activity was observed in a variety of tumor types, including "cold tumors" and PD-(L)1 refractory/resistant patients;

(3) Most patients are still receiving ongoing treatment.

We will present the Phase I clinical study data of CS2009 at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Annual Meeting in October.

Global Phase II trials deepen coverage of multiple cancer types

The global multi-center Phase II trial, which has been launched, adopts a multi-cohort parallel expansion design and will cover 15 cohorts and multiple solid tumor indications, focusing on evaluating the safety, tolerability, PK/PD characteristics and efficacy of CS2009 as a single agent and in combination therapy. Specific study cohorts include:

1. Non-small cell lung cancer (NSCLC):

Monotherapy for treatment -naive patients with PD-L1-positive (tumor proportion score [TPS] ≥ 1%) and negative targetable driver gene alterations (AGA);
