"Over 50 million eligible Americans do not get recommended screenings for colorectal cancer, partly because current screening methods are inconvenient or unpleasant," said AmirAli Talasaz, Guardant Health co-CEO. "We believe the publication of the ECLIPSE study in The New England Journal of Medicine, one of the world’s leading medical journals, is an endorsement of the quality of our clinical data and the potential value of the Shield test. We are confident that offering an accurate blood test has the potential to significantly reduce preventable colorectal cancer deaths."

One of the largest studies of its kind, ECLIPSE (Evaluation of ctDNA LUNAR Assay In an Average Patient Screening Episode) is a 20,000+-patient registrational study to evaluate the performance of Shield compared to a screening colonoscopy. The Shield test detects colorectal cancer signals in the bloodstream from DNA that is shed by tumors, called circulating tumor DNA (ctDNA).

Highlights of the study results to be published in The New England Journal of Medicine* show that Shield demonstrated:

83% sensitivity in detecting individuals with CRC
88% sensitivity in detecting pathology-confirmed Stages I-III
Sensitivity by stage of:
65% for pathology-confirmed Stage I; 55% for clinical Stage I
100% for Stage II
100% for Stage III
100% for Stage IV
These results are on par with the performance of other guideline-recommended non-invasive screening modalities, where overall sensitivity in detecting colorectal cancer ranges from 74% to 92%.1

"More than 3 out of 4 Americans who die from colorectal cancer are not up to date with their recommended screening,2 highlighting the need for a more convenient and less invasive screening method that can overcome barriers associated with traditional options," said Daniel Chung, MD, gastroenterologist at Massachusetts General Hospital and Professor of Medicine at Harvard Medical School. "The ECLIPSE study results published today support the use of a blood test as a screening option that could help overcome these barriers and improve CRC screening rates."

Publication of ECLIPSE follows Guardant Health’s submission of its premarket approval (PMA) application to the U. S. Food and Drug Administration (FDA) for Shield, which included key data points from the study. Since the launch of the lab-developed version of the Shield test in May 2022, it has been used by more than 20,000 people and more than 90% of patients who were prescribed the test in the real-world clinical setting completed it. One recent study showed that CRC screening rates tripled among adults who had declined prior CRC screening when they were offered Shield. The test’s sensitivity in detecting CRC, combined with this real-world adherence, suggests that Shield has the potential to detect more CRCs at a curable stage than traditional screening methods.3,4,5,6

"Colorectal cancer is highly treatable if caught in the early stages, yet more than 50 million people in the U.S. are still not completing their recommended screening with the methods available today," said Chris Evans, president of the Colon Cancer Coalition. "This publication gets us one step closer to having an additional option to offer patients – one that is both convenient and accessible—and will help us close the screening gap."

Colorectal cancer is the second-leading cause of cancer deaths in the U.S. The American Cancer Society estimates that more than 150,000 people will be diagnosed with CRC in 20247 and it is expected to become the leading cause of cancer-related deaths by 2030 in adults aged 20-49.8 More than 75% of people who die from CRC are not up to date with recommended screening,9 often due to the perception that current methods such as colonoscopy or stool-based tests are invasive, time-consuming and inconvenient. Early detection, however, is crucial. When colon cancer is found at an early stage before it has spread, the 5-year relative survival rate is 91%. If the cancer has spread to distant parts of the body, the 5-year survival rate is 13%.

"The results of the study are a promising step toward developing more convenient tools to detect colorectal cancer early while it is more easily treated," said corresponding author William M. Grady, MD, a gastroenterologist at Fred Hutchinson Cancer Center. "The test, which has an accuracy rate for colon cancer detection similar to stool tests used for early detection of cancer, could offer an alternative for patients who may otherwise decline current screening options."

About the ECLIPSE study

ECLIPSE is a prospective registrational study to evaluate the performance of Guardant Health’s blood test in detecting signs of CRC compared to a screening colonoscopy in average-risk adults between the ages of 45 and 84 from across the U.S. The ECLIPSE study included more than 200 clinical trial sites in rural and urban communities across 34 states. Study data includes 12% Black, 13% Hispanic and 7% Asian American populations. Enrollment among Black Americans was above average for a clinical trial, which is important given the disproportionate impact of CRC on the Black community.10

About Shield

The Shield test for colorectal cancer screening is commercially available for eligible individuals by prescription only through healthcare professionals. This LDT (Laboratory Developed Test) is intended to be complementary to, and not a replacement for, current recommended CRC screening methods. A negative result does not rule out the presence of cancer. Patients with an abnormal blood-based screening result should be referred for a diagnostic colonoscopic evaluation.

More information about the Shield test is available at bloodbasedscreening.com.

Zai Lab to Present Data Highlighting ZL-1310, a Novel Antibody-Drug Conjugate (ADC) for Treatment of Solid Tumors

On March 13, 2024 Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) reported that it will present findings from preclinical studies highlighting the therapeutic potential of ZL-1310, the company’s global next-generation antibody-drug conjugate (ADC) program (Press release, Zai Laboratory, MAR 13, 2024, View Source [SID1234641126]). The preclinical profile of ZL-1310 will be the focus of a poster presentation at the European Lung Cancer Congress 2024 (ELCC 2024), scheduled for March 20-23, 2024 in Prague, Czech Republic.

ZL-1310 is a novel and promising ADC within the Zai Lab global oncology R&D pipeline, targeting the Delta-like ligand 3 (DLL3), a validated therapeutic target in the treatment of small cell lung cancer (SCLC). DLL3, which is expressed on the cell surface of most SCLC, plays a pivotal role in promoting SCLC cell proliferation, migration and invasion.

"ZL-1310 has high affinity for the target, DLL3, and releases its payload both intracellularly and in the tumor microenvironment, also allowing for bystander effect of its camptothecin-derived payload," said Rafael G. Amado, M.D., president, head of Global Oncology Research and Development, Zai Lab. "The encouraging preclinical data we will present at ELCC 2024 formed the basis for the ZL-1310 Phase 1 clinical trial that we initiated in January of this year."

Data from the preclinical IND-enabling studies which will be shared at ELCC 2024 indicate that ZL-1310 exhibits a strong and specific binding to DLL3 on the cell surface, leading to internalization, cell cycle arrest and the induction of apoptosis in tumor cells. In-vivo, ZL-1310 effectively suppressed the growth of established human tumors in a dose-dependent manner in both cancer cell-derived (CDX) and SCLC patient sample-derived (PDX) xenograft models.

ZL-1310 was discovered with MediLink Therapeutics’ proprietary TMALIN platform, a next-generation ADC platform designed to leverage the tumor microenvironment to overcome the challenges with current ADC drugs. Zai Lab entered a partnership and exclusive worldwide license agreement with MediLink in April 2023. Subsequently, in January 2024, Zai Lab initiated a global Phase 1 study of ZL-1310 in patients with relapsed and refractory SCLC who have progressed after platinum-based treatment.

Details regarding the poster presentation at ELCC 2024 are as follows:

Title: Development and characterization of a novel DLL3-targeting antibody drug conjugate (ADC) for the treatment of solid tumors
Presenter: Linda N Liu, Senior Vice President, Biologics Discovery, Zai Lab
Date/Time: Friday, March 22, 2024, 12:00 PM – 12:45 PM CET
Location: Prague Congress Centre, Congress Hall Foyer

About Small Cell Lung Cancer (SCLC) and Neuroendocrine Tumors

SCLC and neuroendocrine tumors are diseases with significant unmet medical needs globally. There are over 300,000 SCLC annual incidences globally.1 More than 88% of SCLC patients overexpress DLL3 and could benefit from targeted therapeutic agents.2 In addition, DLL3 is a promising target highly expressed in several tumors with neuroendocrine features. There are approximately 171,000 people living with neuroendocrine tumors in the United States, and the numbers are continuing to increase, but the treatment options remain limited.

Poseida Therapeutics Announces FDA Orphan Drug Designation Granted to P-BCMA-ALLO1 for the Treatment of Multiple Myeloma

On March 13, 2024 Poseida Therapeutics, Inc. (Nasdaq: PSTX), a clinical-stage cell and gene therapy company advancing a new class of treatments for patients with cancer and rare diseases, reported the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation for the treatment of multiple myeloma to P-BCMA-ALLO1, a novel BCMA-targeted allogeneic, T stem cell memory (TSCM)-rich chimeric antigen receptor (CAR)-T therapy candidate (Press release, Poseida Therapeutics, MAR 13, 2024, View Source [SID1234641125]). The Company is investigating P-BCMA-ALLO1 in partnership with Roche for the treatment of relapsed/refractory multiple myeloma (RRMM).

"The Orphan Drug Designation for P-BCMA-ALLO1 underscores the high unmet medical need for a rapid and accessible off-the-shelf allogeneic CAR-T therapy for patients with multiple myeloma," said Kristin Yarema, Ph.D., President and Chief Executive Officer of the Company. "This designation further validates our belief that TSCM-rich allogeneic CAR-T therapies may potentially offer the optimal combination of clinical results, on-demand availability, and high-volume production, while supporting broader access to CAR-T therapies. We look forward to continuing our work on the Phase 1 study of P-BCMA-ALLO1 and plan to share further clinical updates in 2024."

The Company is currently evaluating P-BCMA-ALLO1 in a Phase 1 clinical trial and recently shared positive early safety and preliminary efficacy data at the 65th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition in December 2023. Data highlighted at the meeting showed that P-BCMA-ALLO1 was a well-tolerated off-the-shelf therapy with a favorable emerging safety profile, delivered to 100% of patients in the intent-to-treat population with no use of bridging chemotherapy or other anti-myeloma bridging therapies. Preliminary data presented at ASH (Free ASH Whitepaper) also showed allogeneic TSCM-rich CAR-T cells trafficking to bone marrow, differentiating to cell-killing effector T cells and persisting at least 6 weeks after treatment, which support the hypothesis of cell persistence at tumor-relevant sites.

The Company will present data on a subset of recently enrolled patients refractory to initial BCMA targeting therapy in a poster presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in San Diego on April 8, 2024, 9:00 AM to 12:30 PM PT.

Subject to coordination with Roche, the Company plans to provide an additional clinical update on the P-BCMA-ALLO1 program at a scientific meeting in the second half of 2024.

The FDA’s Orphan Drug Designation program provides orphan status to drugs or biologics intended for the prevention, diagnosis, or treatment of diseases that affect fewer than 200,000 people in the United States. Sponsors of medicines that are granted Orphan Drug Designation are entitled to certain incentives, including tax credits for qualified clinical trials, prescription drug user-fee exemptions, and potential seven-year marketing exclusivity upon FDA approval.

About P-BCMA-ALLO1

P-BCMA-ALLO1 is an allogeneic CAR-T product candidate licensed to Roche targeting B-cell maturation antigen (BCMA) for the treatment of relapsed/refractory multiple myeloma. This allogeneic program includes a VH-based binder that targets BCMA and clinical data presented at ASH (Free ASH Whitepaper) in December 2023 support the Company’s belief that TSCM-rich allogeneic CAR-Ts have the potential to offer effective, safe, and reliable treatment addressing unmet needs in multiple myeloma. Additional information about the Phase 1 study is available at www.clinicaltrials.gov using identifier: NCT04960579.

We have already started two Phase II studies of RVU120, and around mid-year, we plan to launch two more Phase II studies in hematology. By the end of the year, we plan to enroll more than 100 patients across these clinical trials. We also plan to launch a new Phase II study of MEN1703 (SEL24) in DLBCL, which is being developed under a license agreement with the Menarini Group. Study start-up activities for new trials of both RVU120 and MEN1703 are proceeding quickly.

Krzysztof Brzozka, Ph.D., Executive Vice President, and Chief Scientific Officer, said:

– We are pleased with the significant progress made in our early-phase projects. Among the most advanced projects from our synthetic lethality platform – PRMT5 and WRN – we plan to identify a clinical candidate in 2024. We are also seeing progress in the programs being developed by our partners – particularly BioNTech and Exelixis. We were excited to achieve the second milestone in the Exelixis collaboration, and we look forward to presenting data on our synthetic lethality assets and novel platform at AACR (Free AACR Whitepaper).

2023 SUMMARY AND RECENT CORPORATE EVENTS

RVU120 clinical development plan

In 2023 Ryvu prepared for the launch of two Phase II RVU120 trials, which then initiated in early 2024: 1) RVU120 as monotherapy in genetically defined cohorts of patients with relapsed/refractory acute myeloid leukemia (r/r AML) and high-risk myelodysplastic syndromes (HR-MDS, RIVER-52 study), and 2) RVU120 in combination with venetoclax for patients with relapsed/ refractory AML (RIVER-81 study).
Ryvu will financially support the REMARK study’s Phase II clinical trial of RVU120 in patients with low-risk myelodysplastic syndromes (LR-MDS). REMARK will be conducted as an investigator-initiated study through the EMSCO network, with Prof. Uwe Platzbecker, a globally renowned expert in the field of LR-MDS, as the Coordinating Principal Investigator. Start-up activities have already been launched, and patient enrollment will start in mid-2024.
Study start-up is also underway for POTAMI-61, a Phase II study evaluating the efficacy of RVU120 in patients with myelofibrosis (MF). Initiation of patient recruitment is scheduled for mid-2024.
Translational research on RVU120 in solid tumors will continue, including combination studies, as well as academic collaborations in the areas of medulloblastoma (MB) and sarcoma-related research.
The company plans to enroll more than 100 patients across all RVU120 Phase II trials this year and aims to present initial Phase II data by the end of 2024.
RVU120’s updated clinical development plan includes studies (RIVER-52, RIVER-81, and POTAMI-61) that could lead to three drug approvals between 2026 and 2027.
Key data presented during 2023 conferences

In 2023, Ryvu Therapeutics presented data from the RVU120 program at several international conferences, including EHA (Free EHA Whitepaper) 2023, ESMO (Free ESMO Whitepaper) 2023, and ASH (Free ASH Whitepaper) 2023:

RVU120 monotherapy demonstrated clinical activity in a Phase Ib study in which 50% of evaluable patients with r/r AML or HR-MDS achieved clinical benefit, including a complete response, morphologically leukemia-free status, clinically significant reduction of blasts including reductions that allowed bridging to a bone marrow transplantation, two-year disease stabilization, hematologic improvements, as well as reduction in bone marrow fibrosis.
In particular, early signs of efficacy were observed in patients with an NPM1 mutation, DNMT3a mutation, and HR-MDS.
The recommended Phase II dose (RP2D) of 250 mg was found to be safe and well-tolerated, achieving RVU120 concentrations in the pharmacologically active range, with a level of target inhibition between 50% and 70%. This level of target inhibition is expected to result in therapeutic efficacy in selected patients or in combinations with synergistic therapies.
RVU120 is emerging as a potential candidate in the first-line treatment of AML, supported by its activity against leukemic stem cells.
RVU120 acts synergistically with venetoclax in both sensitive and venetoclax-resistant models.
At the ENA conference in October 2023, Ryvu presented preclinical data for PRMT5 and the synthetic lethality platform, and Ryvu’s partner – Menarini Group, presented preclinical data for MEN1703 in advanced diffuse large B-cell lymphoma (DLBCL).

Ryvu has developed potentially best-in-class MTA-cooperative PRMT5 inhibitors with outstanding drug-like physicochemical properties and the ability to block methyltransferase activity of PRMT5 with nanomolar concentrations and bioavailable upon oral administration. The novel, optimized inhibitors exhibit a significantly improved pharmacokinetic profile. In addition, the compounds show antitumor efficacy and target engagement in vivo, providing a solid foundation for further development towards clinical trials.
MEN1703 (SEL24) has shown promising antitumor activity in translational studies in various types of DLBCL. These data justify the development of MEN1703 in Phase II clinical trials in this indication.
Expansion of MEN1703 (SEL24) development by Ryvu’s partner – Menarini Group, to include a new Phase II clinical trial in DLBCL.

In September 2023, Ryvu announced the Menarini Group’s decision to expand the development of MEN1703 (SEL24) by initiating a new Phase II clinical trial in patients with DLBCL.

A Phase II study in DLBCL is scheduled to begin in mid-2024. The goal is to evaluate the activity of MEN1703 (SEL24) as monotherapy and in combination with standard therapy in patients with DLBCL.
The study will be initiated based on the potent activity of MEN1703 (SEL24) observed in preclinical lymphoma models. Clinical trials have confirmed the acceptable safety profile and early signs of activity of MEN1703 (SEL24) as a monotherapy. Based on the available data, further program development will continue in patients with DLBCL and potentially in additional indications.
Recent financial events

On February 3, 2024, Ryvu received notice that the second financial milestone was achieved under the collaboration agreement with Exelixis, resulting in a $2M payment to Ryvu. Ryvu and Exelixis are working under a research collaboration and license agreement to develop antibody-drug conjugates (ADCs) with Ryvu’s portfolio of STING agonists.
On March 5, 2024, Ryvu received notice from the European Investment Bank (EIB) that it had met the conditions for disbursement of the first venture debt tranche of €8M. These funds are not yet included in the cash balance reported in this press release, but Ryvu expects to receive the funds on March 13, 2024. As part of the agreement announced in August 2022, Ryvu still has access to an additional €14M in venture debt from the EIB.
UPCOMING EVENTS

Ryvu will attend the AACR (Free AACR Whitepaper) Annual Meeting (San Diego, USA) from April 5-10, 2024, to present preclinical data from its synthetic lethality pipeline, RVU120, and MEN1703 (SEL24).

Survival outcomes according to molecular classification of uterine carcinosarcoma
Walking Poster Session | Walking Poster Group 5: Cancer Care Delivery
March 17: 8:15 – 8:45 AM PST

Uterine carcinosarcoma (UCS) is an aggressive cancer with a poor prognosis, yet there are limited studies evaluating its molecular subtypes and their association with survival outcomes. In this new study, more than 4,000 UCS and endometrioid endometrial cancer (EEC) tumors were evaluated using next-generation sequencing (NGS) to determine if UCS molecular subtype governs survival. This is the first study to report survival outcomes according to molecular classification in UCS compared to an EEC cohort.

Frequency and outcomes of co-mutations according to ProMisE classifiers in endometrial cancer
Poster Session I
March 17: 1:15 – 1:45 PM PST

The Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) criteria classify four molecular subtypes of endometrial tumors (ET). However, there is limited understanding of how the presence of alterations in multiple classifiers affects ET prognosis. Whole exome sequencing of over 5,100 ETs revealed that some ETs have overlapping molecular subtypes.
Molecular characterization of squamous cell ovarian cancers for identification of therapeutic targets
Poster Session I
March 17: 1:15 – 1:45 PM PST

Not all ovarian cancers have the same prognosis; ovarian squamous cell carcinoma (OSCC), for example, is associated with a worse prognosis than high-grade serous ovarian cancer (HGSOC). Through NGS of DNA and RNA from ovarian tumors (OSCC, HGSOC, and Brenner’s tumors), this study sought to identify prognostic factors and molecular markers associated with OSCC. High tumor mutational burden (TMB) and lack of ER, PR expression were found to be molecular characteristics of OSCC, along with other distinct patterns of molecular and immune markers. Further characterization of OSCC may lead to the identification of therapeutic targets.
Poster and abstract summaries highlighting the Caris research presented at SGO 2024 will be available onsite at Caris’ booth (#601). The full abstracts will be available on the Caris website beginning on March 16.

The POA includes 91 cancer centers, academic institutions, research consortia and healthcare systems, including 43 NCI-designated cancer centers, collaborating to advance precision oncology and biomarker-driven research. POA members work together to establish and optimize standards of care for molecular testing through innovative research focused on predictive and prognostic markers that improve the clinical outcomes for cancer patients.
