Global collaboration aims to advance breast cancer treatments
A research group bringing together 1,400 cancer centres and 21,000 oncology researchers is collaborating with a life sciences firm to target new breast cancer treatments.
ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) and Caris Life Sciences have announced a multi-year research collaboration.
Caris is pairing its genomic expertise and AI and machine learning algorithms with ECOG-ACRIN’s vast research capability.
The first project is underway and leverages the tumour tissue samples from the TAILORx (trial assigning individualised options for treatment – Rx), breast cancer clinical trial.
TAILORx is one of the world’s largest breast cancer research resources.
It will explore early-stage breast cancer, where the risk of recurrence is a primary concern for many people.
Approximately 60 per cent of newly-diagnosed breast cancer cases are in the early stage, with no spread to surrounding lymph nodes.
While there has been an overall 42 per cent decline in breast cancer deaths over the last 30 years—due to increased use of mammograms, earlier diagnoses, and more effective treatments—there is a persistent mortality gap between minority patients and white patients.
A TAILORx analysis published in JAMA Surgery is the first to show that racial and ethnic differences in locoregional breast cancer recurrence patterns are prevalent even in a clinical trial population with similar access to care.
As part of its new collaboration, Caris will perform comprehensive molecular characterisation on tumour tissues contributed by nearly 10,000 patients with early-stage breast cancer who participated in the TAILORx trial.
Participants have been followed for 11 years or more, with planned follow-up for 20 years.
Caris will couple its molecular testing with its advanced AI and machine learning algorithms. Data from the project will also be made publicly available after a designated time-period following completion of the research project plan in an appropriate NCI database.
Peter O’Dwyer, group co-chair of ECOG-ACRIN, said: “Our collaboration with Caris has deep roots, aligned interests, and a commitment to develop the best science in the service of early detection and treatment of cancer. The promise of the joint effort is to provide broad availability of cutting-edge options for cancer patients in their communities.”
George Sledge, chief medical officer of Caris, said:“I’m excited to build on the trial’s initial findings which prevented millions of women with early breast cancer from having to endure toxic treatments, to continue discerning valuable insights related to long term recurrence risk and to identify even more women who may benefit from more efficient treatment options.
“It is truly a full circle moment for me, as I’ve been involved with this landmark biomarker trial–the largest ever sponsored by the NCI–during trial development, patient enrollment, findings reporting and now the next phase of research of TAILORx with Caris.”
Mitchell Schnall, group co-chair of ECOG-ARIN, says: “Given the innovative capabilities offered by Caris, analysis of TAILORx biospecimens with cutting-edge AI approaches provides a great opportunity to discover superior biomarkers for risk stratification, prediction of recurrence and better understanding of racial disparities. The size and impact of TAILORx makes it a perfect study to lead off this collaboration.”
ECOG-ACRIN is a membership organisation that designs and conducts cancer research involving adults who have or are at risk of developing cancer.
It comprises nearly 1400 member institutions and 21,000 research professionals globally.
It is funded primarily by the US-based National Cancer Institute, part of the National Institutes of Health.
The FDA has granted accelerated approval to AstraZeneca drug Etcamah for certain adults with advanced breast cancer carrying an ESR1 mutation.
Etcamah, also known as camizestrant, was approved in combination with a CDK4/6 inhibitor, either abemaciclib, palbociclib or ribociclib.
The treatment is for adults with hormone receptor-positive, HER2-negative, locally advanced or metastatic breast cancer when an estrogen receptor-1 (ESR1) mutation is detected during aromatase inhibitor and CDK4/6 inhibitor therapy using an FDA-authorised test.
ESR1 mutations are acquired resistance mutations that tumours may develop during treatment with aromatase inhibitors, a type of endocrine therapy commonly used as a front-line treatment for locally advanced or metastatic breast cancer.
Fewer than 5 per cent of patients have the mutation when HR-positive metastatic breast cancer is diagnosed, according to the FDA. After disease progression on an aromatase inhibitor, nearly 40 per cent have the mutation.
Acting FDA commissioner Kyle Diamantas said: “Women living with metastatic breast cancer face an uphill battle as their tumors continuously evolve to escape treatment.
“We owe them every weapon in our arsenal.
“Today’s approval delivers a win to these patients by granting them a targeted therapy designed specifically to overcome resistance, giving them more time before their disease progresses.”
The accelerated approval programme allows earlier approval of drugs that treat serious conditions and fill an unmet medical need based on surrogate or intermediate endpoints.
For Etcamah, approval was based on how long patients lived without their disease worsening, measured from when the resistance mutation was first detected in their blood.
The FDA said it has not yet been confirmed whether intervening when the mutation is detected, rather than waiting until disease progression is confirmed, results in a clinically meaningful benefit. Confirmatory studies are therefore required to verify and describe clinical benefit.
Angelo de Claro, director of the FDA’s Oncology Center of Excellence, said: “I commend both the FDA and the sponsor for their commitment to advancing cancer care and securing this accelerated approval.
“This marks the first FDA approval of a cancer therapy guided by the detection of a resistance mutation in circulating tumor DNA (ctDNA) before imaging tests show that the disease is progressing.
“But additional evidence is needed to confirm clinical benefit.”
Circulating tumour DNA, or ctDNA, consists of small pieces of tumour DNA released into the blood and can allow earlier molecular detection of resistance mutations.
The FDA also authorised the Guardant360 CDx assay as a companion diagnostic to identify patients with breast cancer who have ESR1 mutations for treatment with camizestrant.
Efficacy was assessed in a clinical trial comparing a switch to Etcamah plus a CDK4/6 inhibitor with continued treatment using an aromatase inhibitor plus a CDK4/6 inhibitor.
Estimated median progression-free survival was 16 months in the Etcamah group, compared with 9.2 months in the aromatase inhibitor group.
Etcamah’s prescribing information includes a boxed warning about the risk of irregular heart rhythm when taken with certain other medicines. It also includes warnings about an abnormally slow heart rate and potential harm to an unborn baby.
The FDA convened its Oncologic Drugs Advisory Committee for the application on 30 April 2026.
Scotland has launched a review of NHS IVF access, including whether treatment should extend to single women and couples with children from previous relationships.
The national review will assess how fertility services can better reflect modern family structures while maintaining fair and consistent access across Scotland.
It will also examine access to fertility preservation services, particularly for women who have undergone cancer treatment, and ways to cut waiting times for patients who need donor eggs or sperm.
Scotland currently offers the most comprehensive nationwide NHS IVF provision in the UK. Eligible patients can access up to three full cycles of IVF treatment through the NHS, subject to existing eligibility criteria.
Ministers will also consider updated clinical guidance from the National Institute for Health and Care Excellence.
The revised recommendations suggest patients who have not achieved a successful pregnancy after three IVF cycles could benefit from up to three additional NHS-funded treatment cycles.
The review is part of the Scottish Government’s commitment to examining how fertility services are delivered and whether they meet patients’ needs across Scotland.
Scottish health secretary Angela Constance said: “Access to NHS IVF treatment should be fair, timely and reflect the way people’s lives and families look today, and delivering this review is one of our key 100 day commitments.
“The review will look closely at the current system, including waiting times for those who need donor eggs or sperm for their treatment.
“This work builds on annual Scottish Government funding, which has supported the expansion of NHS IVF treatment over the past ten years.”
Healthcare leaders and fertility specialists will be watching closely as the review progresses, with any future changes potentially broadening access to treatment and addressing long-standing concerns around equity, consistency and waiting times.
Women’s health medical device company Ark Surgical has secured further institutional backing from JNF and the Israel Innovation Authority (IIA) as it accelerates the US commercial expansion of its surgical tissue containment technology.
Both organisations have previously backed Ark, making the renewed support a significant vote of confidence in the company’s technology, leadership team and commercial strategy as it moves into its next stage of growth.
The new backing comes alongside Ark Surgical’s ongoing Series A financing round, which has also attracted investment from physicians and experienced medical device executives, adding further industry validation as the company builds its US commercial presence.
The Israel Innovation Authority, Israel’s public agency supporting technological innovation, selected Ark Surgical for additional non-dilutive funding following an extensive evaluation process.
The assessment examined the unmet clinical need addressed by Ark’s technology, its clinical results, business and US go-to-market strategy, Israeli and US teams, execution against milestones and future product pipeline.
JNF, which supports economic development and community-building initiatives in Israel, has also increased its previous backing of Ark Surgical.
The relationship has particular significance given Ark’s roots in northern Israel. The company is headquartered near Nazareth in the Galilee and plans to continue strengthening its manufacturing capabilities in the region as its commercial presence in the US grows.
Together, the continued institutional support and investment from experienced healthcare leaders reflect growing confidence in Ark’s technology and its strategy for US expansion.
Stav Tori, CEO of Ark Surgical, said: “Having organisations that already know Ark, our technology and our team choose to support us again is particularly meaningful.
“It reflects our ability to consistently achieve the clinical, regulatory and commercial milestones we set and gives us additional resources to accelerate our expansion in the US.
“Our ambition goes beyond bringing another medical device to market.
“We want to help establish a higher standard of surgical safety for women undergoing minimally invasive procedures.”
Addressing an overlooked risk in women’s surgery
At the centre of Ark’s expansion is LapBox, the company’s FDA-cleared dual-wall tissue containment system developed to address an important safety challenge in minimally invasive gynecologic surgery.
Procedures such as hysterectomy and myomectomy can require large uterine specimens or fibroids to be divided into smaller pieces so they can be removed through small laparoscopic incisions.
This process, known as morcellation, carries a risk of disseminating tissue within the abdominal cavity.
In rare cases where an unsuspected malignancy is present, morcellation can spread malignant tissue and potentially worsen a patient’s prognosis.
But the risk is not limited to cancer.
Even benign uterine tissue can implant elsewhere in the abdominal cavity and grow, potentially resulting in complications such as parasitic fibroids and the need for additional treatment.
LapBox was developed as a dual-wall, bag-in-bag containment system that creates a secured chamber for tissue extraction. The device is FDA-cleared for use with both manual and power morcellation.
From clinical innovation to US adoption
Ark Surgical is now moving beyond its clinical and regulatory milestones to focus on broader commercial adoption.
LapBox™ has already been used in hundreds of procedures, while Ark has been expanding its presence within US hospitals and building relationships with leading minimally invasive gynecologic surgeons.
The latest institutional backing will support the next stage of that strategy, including additional hospital partnerships, key opinion leader engagement, sales leadership and clinical support.
Joseph LaBruzzo, President and CEO of U.S. Operations at Ark Surgical, said: “Ark has reached an important point in its development.
“We have the regulatory clearance, growing clinical experience and increasing engagement from US surgeons and hospitals.
“The focus now is execution and scale.
“What makes this continued backing particularly meaningful is that these are organizations that have followed Ark’s development and seen the team deliver against its objectives.
“Their decision to support the company again provides further validation as we build the commercial and clinical infrastructure needed for broader US adoption.”
That growing adoption is also being reflected in the experience of surgeons using LapBox.
Dr Ramon Yera, a minimally invasive gynecologic surgeon with more than 35 years of experience, said: “Once surgeons use LapBox, they realize this is the bag they should be using for their bread-and-butter procedures.”
Yera believes this reflects a broader shift in expectations around tissue containment in gynecologic surgery.
“Containment is no longer optional. It is an expectation.”
Ark Surgical is continuing its Series A financing round, with additional capital intended to support the next phase of US commercial expansion and development of its broader product pipeline.
