The study, which assessed the clinical utility and performance of Merlin test in T1a melanoma patients, showed that it dramatically improves the ability to differentiate between low- and high-risk T1a patients. Merlin test identified 88% of patients as Low Risk, resulting in a post-test SLN positivity rate of only 1.5% among those classified as Merlin Low Risk. Conversely, 12% of patients were classified as High Risk, with a significantly higher SLN positivity rate of 15.8% among those identified as Merlin test High Risk. These findings highlight the test’s potential to reduce unnecessary SLNB surgeries, preventing overtreatment in the vast majority of patients while ensuring high-risk individuals receive appropriate care.

Alexander Meves, M.D., MBA, dermatologist at Mayo Clinic and principal inventor of the CP-GEP model, shared: "The intent is to help prevent undertreatment in seemingly low-risk early-stage melanoma patients who are actually at risk for nodal metastasis. By accurately identifying these at-risk individuals, we ensure that they receive the necessary interventions, even in the absence of traditional clinical risk factors."

For patients with at least one traditional adverse feature, such as age under 40, lymph vascular invasion, or a high mitotic rate, Merlin test identified 37 patients as Low Risk, all with a post-test SLN positivity rate of 0%. Additionally, among 104 patients without any adverse features, the Merlin test still identified 7 patients as High Risk, with a post-test SLN positivity rate of 14.3%. These results demonstrate that Merlin test effectively pinpoints high-risk individuals who might otherwise go untreated under traditional guidelines.

This latest data highlights the importance of Merlin test in transforming early-stage melanoma treatment. Merlin test provides clinicians with a robust, evidence-based tool to tailor SLNB surgery decisions, minimizing unnecessary surgeries while ensuring that high-risk patients receive appropriate care. With the ongoing advancements in genomic testing and personalized medicine, the Merlin test offers a new standard of care that has the potential to improve outcomes for countless melanoma patients.

About CP-GEP (Merlin test)

CP-GEP is a non-invasive prediction model for cutaneous melanoma patients that combines clinicopathologic (CP) variables with gene expression profiling (GEP). This model is able to stratify patients based on being high or low risk for metastasis and thereby categorize them in the appropriate surgical action categories listed in evidence-based cancer treatment, prevention and screening guidelines. The CP-GEP model was developed by Mayo Clinic and SkylineDx BV and it has been clinically validated in multiple studies. More information (including references) may be obtained at www.falconprogram.com and www.merlinmelanomatest.com. The test has been launched in the United States and Europe as Merlin test. SkylineDx collaborates with diagnostic service providers globally to bring this test to market and increase access. In the United States, Tempus is commercializing the Tempus Merlin test.
Quest Diagnostics launched their own LDT version of the CP-GEP model in the United States under the brand name MelaNodal Predict.

"We continue to make great progress and remain focused on execution as we advance our pipeline of wholly owned and partnered programs in oncology, inflammation and immunology," said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. "As we approach the end of the year, we are well capitalized and look forward to building further momentum as we head into clinical data readouts in the fourth quarter of 2024 and the initiation of pivotal studies of NX-5948 in 2025."

Recent Business Highlights

•Expanded clinical development of NX-5948: In the third quarter of 2024, Nurix initiated the Phase 1b portion of its ongoing Phase 1a/b clinical trial in adults with relapsed or refractory B-cell malignancies. The Phase 1b expansion includes a randomization to a low dose (200mg QD) or a high dose (600mg QD) of NX-5948 in patients with chronic lymphocytic leukemia (CLL) who have been treated with at least two prior regimens including a Bruton’s tyrosine kinase (BTK) inhibitor and a BCL2 inhibitor. This is the patient population for which the FDA granted Nurix Fast Track designation in January 2024. Cohorts were also initiated to evaluate NX-5948 in patients with Waldenstrom’s macroglobulinemia (WM), marginal zone lymphoma and follicular lymphoma.

•Re-initiated enrollment in NX-2127 Phase 1a/b trial: Nurix recently reinitiated enrollment with its new chirally controlled drug product in a standard dose escalation study within the current Phase 1a/1b trial. As previously announced, in March 2024, the U.S. Food and Drug Administration (FDA) lifted a manufacturing-related, partial clinical hold on the NX-2127 clinical trial. Patients enrolled prior to the partial clinical hold who are deriving clinical benefit continue to receive uninterrupted treatment with the original drug product.

•Presented early preclinical data from ongoing collaboration with Pfizer to develop Degrader-Antibody Conjugates, a new class of therapeutics: On September 10, 2024, at the ADC & Radiopharmaceuticals Pharma & Biotech Partnering Summit, Nurix’s chief scientific officer, Gwenn M. Hansen, Ph.D., presented an outline of the advantages of DACs, Nurix’s matrixed approach to the generation and optimization of DACs using its DELigase platform, and early preclinical data demonstrating cell-type selective degradation of targeted proteins by DACs. Nurix believes that DACs may represent a next generation of antibody drug conjugate (ADC) technology that could broaden its use in oncology and potentially other indications. DACs combine the catalytic activity of a targeted protein degrader with the tissue specificity of an antibody which has the potential to provide improved therapeutic index and broader applicability than standard ADCs and which can potentially be applied to any protein target in any tissue.

Upcoming Program Highlights*

NX-5948: NX-5948 is an investigational, orally bioavailable degrader of BTK that is currently being evaluated in the Phase 1b portion of a Phase 1a/b clinical trial in adults with relapsed or refractory B-cell malignancies. By year-end 2024, Nurix plans to present additional clinical data from this study for patients with CLL. Later this month, at the 12th International Workshop on Waldenstrom’s Macroglobulinemia (IWWM 12), Nurix will present a clinical update from this study on patients with WM. Additional information on the Phase 1a/b clinical trial can be accessed at www.clinicaltrials.gov (NCT05131022).

"The precise design enabled by Sutro’s cell-free platform has allowed us to develop ADCs with a wide range of features that are not currently possible with other cell-bound approaches," said Hans-Peter Gerber, Ph.D., Sutro’s Chief Scientific Officer. "This includes the ability to safely increase potency and combine different payloads to overcome specific limitations such as tumor resistance. Today we are highlighting key data supporting our advancements in these areas, along with the long-term potential of our platform to deliver new ADC innovation. This includes plans for three IND filings for wholly owned programs over the next three years and the advancement of additional differentiated preclinical programs for internal development or external partnering."

The event will feature presentations by members of Sutro’s senior management team, functional leaders and Peter Sandor, M.D., EVP and Head of Corporate Strategy at Astellas Pharma (previously SVP, Primary Focus Lead Immuno-Oncology at Astellas, with responsibility for the Sutro-Astellas strategic collaboration to advance iADCs). Sutro management will participate in a Q&A session at the end of the presentation.

Next-Generation ADC Innovation:

Making ADCs better outside the tumor: Sutro’s proprietary cell-free platform enables key elements of ADC design that are intended to reduce platform toxicities associated with current-generation ADCs, including interstitial lung disease; skin, eye, liver and kidney toxicities; and thrombocytopenia. This includes transformational technology across the design of antibodies, payloads, linker and conjugation chemistry that have been demonstrated in preclinical models to reduce toxicities and improve pharmacokinetics.
Making ADCs better inside the tumor: Sutro highlights three approaches enabled by its cell-free platform: 1) increasing potency safely with higher drug-antibody ratio (DAR) exatecan ADCs; 2) combining payloads to overcome tumor resistance with dual-payload ADCs (ADC2); and 3) delivering next-generation immuno-oncology therapeutics with immunostimulatory ADCs (iADC) that combine immune activation with cytotoxic payloads.
Data Highlights and Near-Term Pipeline Milestones:

STRO-004, a tissue factor-targeting ADC, which features a DAR8 exatecan payload and site-specific linker design, demonstrated greater anti-tumor activity and lower toxicities than a tissue factor benchmark ADC in preclinical models. Sutro anticipates filing an IND for STRO-004 with the U.S. Food & Drug Administration in the second half of 2025.
Dual-payload ADCs (ADC2) provide therapeutic benefits compared to standard ADCs, including overcoming tumor resistance mechanisms, showing increased anti-tumor activity and desirable properties in preclinical models.
iADCs provide a novel mechanism of action, bridging innate and adaptive immunity to enable broad protection in a single molecule, and show increased and durable anti-tumor activity in a preclinical model compared to standalone ADCs or immune-stimulating antibody conjugates.
Sutro’s proprietary and partnered preclinical ADC portfolio has potential across a broad range of tumor types and the Company plans to deliver three INDs over the next three years, including for STRO-004 in the second half of 2025. The Company also intends to advance a deep pipeline of preclinical programs, providing further potential for internal development and/or partnering.

FDA Approves Genentech’s Itovebi, a Targeted Treatment for Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer With a PIK3CA Mutation

On October 10, 2024 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported "The PI3K pathway plays a pivotal role in disease progression and has been challenging to target," said Komal Jhaveri, M.D., section head for the endocrine therapy research portfolio and clinical director of the early drug development service at Memorial Sloan Kettering Cancer Center, and one of the principal investigators of the INAVO120 study (Press release, Genentech, OCT 10, 2024, View Source [SID1234647149]). "The Itovebi-based regimen more than doubled progression-free survival and maintained a manageable safety and tolerability profile, adding a new standard in how PIK3CA-mutated breast cancers are treated."

"With the approval of this Itovebi-based regimen, we continue our long-standing track record of cancer therapeutic discovery by offering an important new first-line option for people living with HR-positive breast cancer with a PIK3CA mutation," said Levi Garraway, M.D., Ph.D., Genentech’s chief medical officer and head of Global Product Development. "Despite the high prevalence of PIK3CA mutations in this setting, treatment options have thus far remained limited, which makes today’s approval all the more significant."

This approval is based on results of the pivotal Phase III INAVO120 study, which showed that the Itovebi-based regimen reduced the risk of disease worsening or death by 57% compared with palbociclib and fulvestrant alone (15.0 months vs. 7.3 months; hazard ratio [HR]=0.43, 95% CI: 0.32-0.59, p<0.0001) in the first-line setting, demonstrating a statistically significant and clinically meaningful benefit. Overall survival (OS) data were immature at the time of primary analysis, but a clear positive trend was observed (stratified HR=0.64, 95% CI: 0.43-0.97, p=0.0338 [boundary of 0.0098]). Follow-up for OS is continuing to the next analysis.

"We are thrilled by the approval of the Itovebi-based regimen, which is a huge step forward for advanced breast cancer patients with a PIK3CA mutation," said Jean Sachs, CEO of Living Beyond Breast Cancer. "It remains critical that all patients have access to early, comprehensive biomarker testing so they can better understand what treatment options may be most beneficial for them and their tumor type."

The Itovebi-based regimen was granted FDA Priority Review and Breakthrough Therapy Designation in May 2024 based on the INAVO120 study results. Data from INAVO120 are also being used for filing submissions to other global health authorities, including the European Medicines Agency. Itovebi will be available in the U.S. in the coming weeks. Early, comprehensive biomarker testing with an FDA-approved test, such as Foundation Medicine’s FoundationOneLiquid CDx, can help identify people with HR-positive, HER2-negative breast cancer with a PIK3CA mutation.

Itovebi is currently being investigated in various combinations across three company-sponsored Phase III clinical studies (INAVO120, INAVO121, INAVO122) in PIK3CA-mutated locally advanced or metastatic breast cancer. We continue to evaluate opportunities to expand our clinical development program to address patient unmet needs in various tumor types across oncology.

About the INAVO120 study

The INAVO120 study [NCT04191499] is a Phase III, randomized, double-blind, placebo-controlled study evaluating the efficacy and safety of Itovebi (inavolisib) in combination with palbociclib and fulvestrant versus placebo plus palbociclib and fulvestrant in people with PIK3CA-mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.

The study included 325 patients, who were randomly assigned to either the investigational or control treatment arm. The primary endpoint is progression-free survival, as assessed by investigators, defined as the time from randomization in the clinical trial to the time when the disease progresses, or a patient dies from any cause. Secondary endpoints include overall survival, objective response rate, and clinical benefit rate.

Beyond INAVO120, Itovebi is currently being investigated in two additional company-sponsored Phase III clinical studies in PIK3CA-mutated locally advanced or metastatic breast cancer in various combinations:

in combination with fulvestrant versus alpelisib plus fulvestrant in HR-positive/HER2-negative breast cancer post cyclin-dependent kinase 4/6 inhibitor and endocrine combination therapy (INAVO121; NCT05646862), and
combination with dual HER2 blockade versus dual HER2 blockade and optional physician’s choice of endocrine therapy as a maintenance treatment in HER2-positive disease (INAVO122; NCT05894239).
About Hormone Receptor (HR)-Positive Breast Cancer

HR-positive breast cancer is the most prevalent type of all breast cancers, accounting for approximately 70% of cases. A defining feature of HR-positive breast cancer is that its tumor cells have receptors that attach to one or both hormones – estrogen or progesterone – which can contribute to tumor growth. People diagnosed with HR-positive metastatic breast cancer often face the risk of disease progression and treatment side effects, creating a need for additional treatment options. The PI3K signaling pathway is commonly dysregulated in HR-positive breast cancer, often due to activating PIK3CA mutations, which have been identified as a potential mechanism of intrinsic resistance to standard of care endocrine therapy in combination with cyclin-dependent kinase 4/6 inhibitors.

What is Itovebi?

Itovebi (inavolisib) is a prescription medicine used in combination with the medicines palbociclib and fulvestrant to treat adults who have hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has an abnormal phosphatidylinositol-3-kinase catalytic subunit alpha (PIK3CA) gene, and has spread to nearby tissue or lymph nodes (locally advanced), or to other parts of the body (metastatic), and has come back after hormone (endocrine) therapy.

Your healthcare provider will test your cancer for abnormal PIK3CA genes to make sure that Itovebi is right for you.

It is not known if Itovebi is safe and effective in children.

Important Safety Information
