This collaboration marks a promising step toward a new generation of RLTs designed to deliver potent radiation targeted directly to cancer cells while minimizing damage to healthy tissues. By leveraging the unique strengths of both platforms, the goal is to create more effective, better-tolerated cancer treatments that improve patient quality of life and expand therapeutic options for difficult-to-treat tumors. AbYLink technology enables regio-selective lysine conjugation, ensuring the radioligand avoids the target binding site and facilitating streamlined, consistent manufacturing.

"We’re intrigued to explore the potential of applying AbYlink conjugation technology to the radio-oncology field," expressed Frederic Levy, Chief Scientific Officer, Debiopharm. "Leveraging our innovative conjugation platform with Alkyon’s engineered antibody scaffolds could open new possibilities for next-generation radiopharmaceuticals with enhanced precision and therapeutic impact."

"This collaboration reflects our shared commitment to expanding the potential of radioligand therapies," said Benjamin Titz, Co-Founder and CEO of Alkyon Therapeutics. "By applying AbYlink to our specialized antibody scaffolds and targeting strategies tailored to the unique architecture of solid tumors, we aim to unlock new therapeutic possibilities and advance care for patients with difficult-to-treat solid tumors."

About AbYlink

AbYlink is a versatile and rapid regio-selective chemical conjugation technology for use in preparing diagnostic or therapeutic conjugates. This one-step method results in stable conjugation at defined and invariable sites on the Fc domain of an antibody or the like, with no impact on antigen-binding regions. It enables a seamless and reproducible conjugation of payloads (e.g., a chelator for radiolabeling, a fluorescent dye or a drug) to antibodies or ADCs. The universal applicability of the technology has been demonstrated for various antibody isotypes and payloads.

On June 12, 2025 Silence Therapeutics plc ("Silence" or the "Company") (Nasdaq: SLN), a global clinical-stage company developing novel siRNA (short interfering RNA) therapies, reported additional data showcasing the SANRECO Phase 1 study of divesiran in patients with polycythemia vera (PV) at the European Hematology Association (EHA) (Free EHA Whitepaper) 2025 Annual Meeting in Milan, Italy (Press release, Silence Therapeutics, JUN 12, 2025, View Source [SID1234653867]).

"The latest data presented at EHA (Free EHA Whitepaper) today continue to demonstrate divesiran’s potential to maintain rapid and durable control of hematocrit and essentially eliminate the need for phlebotomies in phlebotomy-dependent PV patients," said Marina Kremyanskaya, MD, PhD, Associate Professor of Medicine, Hematology and Medical Oncology, at the Icahn School of Medicine at Mount Sinai. "These early findings also suggest the potential for infrequent dosing and continue to support a favorable safety profile. I’m very encouraged by the consistency of the Phase 1 dataset and look forward to further development."

"Divesiran continues to demonstrate a very compelling profile as the first-in-class siRNA for PV," said Craig Tooman, President and Chief Executive Officer at Silence Therapeutics. "We are extremely encouraged by the support we are garnering from the physician community and that’s reflected in the positive momentum we’re seeing in the SANRECO Phase 2 study. The Phase 2 study is over 50-percent enrolled, and we remain on-track to complete patient enrollment by the end of this year."

Summary of Updated SANRECO Phase 1 Study Results

Results included 21 phlebotomy-dependent PV patients with a combined history of 79 phlebotomies prior to dosing. Therapeutic phlebotomies were essentially eliminated and mean hematocrit (HCT) levels were lowered and maintained to ≤ 45% for all cohorts regardless of baseline levels.
Divesiran increased hepcidin and ferritin, resulting in elevation of iron body content and improved iron deficiency.
Divesiran demonstrated similar results in all patient groups, independent of baseline risk or prior and concurrent therapy.
White blood cells were not altered over the time-course of the study.
Platelets increased, reaching a plateau with no dose dependent effect.
Divesiran was well tolerated with no dose-limiting toxicities.
SANRECO Phase 1 Study Design
The Phase 1 portion of SANRECO was a 34-week, open-label study evaluating divesiran (3 mg/kg, 6 mg/kg and 9 mg/kg) administered subcutaneously every 6 weeks for four doses, with a 16-week follow-up period following the date of the last administered dose in 21 PV patients. Key inclusion criteria included a PV diagnosis and a history of requiring at least three phlebotomies in the last six months or five in the last year prior to screening. Patients were allowed to be on stable doses of cytoreductive agents. Given the exploratory nature of this Phase 1 study, both well-controlled patients – defined as those with HCT levels at 45% or less – as well as those with HCT levels greater than 45% at baseline on current standard of care treatment were enrolled.

SANRECO Phase 2 Study Design
The Phase 2 portion of SANRECO is now enrolling PV patients and is a randomized, double-blind study evaluating two different divesiran regimens versus placebo. Key inclusion criteria include a PV diagnosis and a history of requiring at least three phlebotomies in the last seven months or five in the last year prior to dosing. Patients are allowed to be on stable doses of cytoreductive agents. Patients must have HCT levels less than 45% prior to dosing. For more information, please click here.

About PV
PV is a rare, myeloproliferative neoplasm – a type of blood cancer – characterized by the excessive production of red blood cells, often resulting in elevated hematocrit levels. Elevated hematocrit above 45-percent is associated with a four-times higher rate of death from cardiovascular or thrombotic events. PV is associated with a range of burdensome symptoms including fatigue, cognitive disturbance and pruritus and additionally, longer term can transform to myelofibrosis and Acute Myeloid Leukemia. The aim of treatment is to maintain hematocrit less than 45%, a level that is associated with a reduced incidence of thrombosis and CV-associated death. The current standard of care includes repeated phlebotomies to reduce hematocrit and/or cytoreductive agents to reduce red blood cell production. There are currently no approved therapies that specifically target red blood cells and hematocrit.

About Divesiran
Divesiran is Silence’s wholly owned siRNA product candidate developed from its proprietary mRNAi GOLD platform that "silences" TMPRSS6 expressed almost exclusively in the liver. TMPRSS6 is a negative regulator of hepcidin, the body’s master regulator of iron metabolism including its absorption, distribution, and storage. By silencing TMPRSS6 in PV patients, divesiran aims to increase hepcidin production and release by liver hepatocytes, leading to the restriction of iron to the bone marrow and, thus, reducing the excessive production of red blood cells, a process dependent on availability of iron. Divesiran is currently in Phase 2 development for PV and has FDA Fast Track and Orphan Drug designations for PV.

On June 12, 2025 Incyte (Nasdaq:INCY) reported that primary results from the Phase 3 POD1UM-303/InterAACT 2 trial of retifanlimab (Zynyz), a humanized monoclonal antibody targeting programmed death receptor-1 (PD-1), in combination with carboplatin and paclitaxel (platinum-based chemotherapy) in adult patients with inoperable locally recurrent or metastatic squamous cell carcinoma of the anal cancer (SCAC) who have not been previously treated with systemic chemotherapy, were published in The Lancet (Press release, Incyte, JUN 12, 2025, View Source [SID1234653866]).

"The publication of the POD1UM-303/InterAACT 2 trial in The Lancet is a testament to the strength of the data generated for retifanlimab in patients with inoperable locally recurrent or metastatic SCAC, a disease which until recently had seen limited innovation for decades," said Steven Stein, M.D., Chief Medical Officer, Incyte. "SCAC can be a devastating disease, and patients often have a poor prognosis. These data supported the U.S. Food and Drug Administration (FDA) approval of Zynyz (retifanlimab-dlwr) in May 2025, providing U.S. patients the first and only first-line treatment for inoperable locally recurrent or metastatic SCAC."

The POD1UM-303/InterAACT2 trial results, which were also featured at a Presidential Symposium on Practice-Changing Trials at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) in 2024, showed that the study met its primary endpoint by demonstrating a statistically significant improvement in progression-free survival (PFS) in patients with inoperable locally recurrent or metastatic SCAC not previously treated with systemic chemotherapy, as assessed by blinded independent central review (BICR) using RECIST v1.1.2 Adding retifanlimab to carboplatin and paclitaxel resulted in a clinically meaningful 37% reduction in the risk of progression or death (Hazard Ratio [HR]: 0.63; 95% Confidence Interval [CI] (0.47, 0.84); P=0.0006).2 Patients in the retifanlimab and chemotherapy combination group achieved a median PFS of 9.3 months compared to 7.4 months for patients in the placebo combination group.2

New data published today in The Lancet show that in patients treated with retifanlimab plus chemotherapy:1

A consistent benefit in PFS in favor of retifanlimab plus chemotherapy was observed for all pre-defined subgroups with sufficient patients for comparison.
A clinically meaningful 6-month difference in overall survival (OS) was observed at the interim analysis (29.2 months in the retifanlimab plus carboplatin and paclitaxel group vs 23.0 months in the placebo plus carboplatin and paclitaxel group). Interim OS results were not statistically significant, and patients continue to be followed for the final key secondary OS analysis.
The overall response rate (ORR) to treatment was improved by the addition of retifanlimab to the chemotherapy (55.8% in the retifanlimab plus carboplatin and paclitaxel group vs 44.2% in the placebo plus carboplatin and paclitaxel group) and the median duration of response was approximately doubled (14 months in the retifanlimab plus carboplatin and paclitaxel group vs 7.2 months in the placebo plus carboplatin and paclitaxel group) when compared to placebo.
As reported in The Lancet, no new safety signals were observed in POD1UM-303/InterAACT2, and safety was consistent with chemotherapy plus checkpoint inhibitor regimens. Serious and Grade 3 or worse adverse events were more frequent in the retifanlimab plus carboplatin and paclitaxel group compared with placebo plus carboplatin and paclitaxel group (47.4% vs 38.8% and 83.1% vs 75.0%, respectively). The most common Grade ≥3 adverse events were neutropenia (35.1% for retifanlimab plus carboplatin and paclitaxel vs 29.6% for placebo plus carboplatin and paclitaxel) and anemia (19.5% vs 20.4%). Despite the higher rate of serious, Grade 3 or worse, and fatal adverse events with retifanlimab plus carboplatin and paclitaxel than placebo plus carboplatin–paclitaxel, these toxicities were manageable with standard measures and carboplatin and paclitaxel delivery was not compromised.

The publication, entitled "Retifanlimab with carboplatin and paclitaxel for locally recurrent or metastatic squamous cell carcinoma of the anal canal (POD1UM-303/InterAACT-2): a global, phase 3 randomised controlled trial," can be found online here.

"The incidence of SCAC is increasing by approximately 3% annually, driven mainly by endemic human papillomavirus (HPV infection). With no approved treatments available for advanced cases until recently, it is crucial to develop effective therapies for this orphan disease," said Sheela Rao, M.D., Consultant Medical Oncologist, The Royal Marsden National Health Service Foundation Trust.

In May 2025, the FDA approved Zynyz (retifanlimab-dlwr) in combination with carboplatin and paclitaxel (platinum-based chemotherapy) for the first-line treatment of adult patients with inoperable locally recurrent or metastatic SCAC. In addition, the FDA granted approval for Zynyz as a single agent for the treatment of adult patients with locally recurrent or with metastatic SCAC with disease progression on or intolerance to platinum-based chemotherapy. Incyte has also submitted a Type II variation Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for retifanlimab in advanced SCAC and in March 2025 submitted and received acceptance of a Japanese New Drug Application (J-NDA) by the Pharmaceuticals and Medical Devices Agency (PMDA) for retifanlimab in advanced SCAC.

About Squamous Cell Carcinoma of the Anal Canal (SCAC)

SCAC is the most common type of anal cancer, making up 85% of cases.3 It is a rare disease for which the incidence is increasing approximately 3% per year.4 About 90% of cases are associated with human papillomavirus (HPV) infection—the number one risk factor for anal cancer.5 HIV is an important amplifier of anal cancer, as people with HIV are 25 to 35 times more likely to develop it.6,7 Anal cancer shares many of the same symptoms as non-cancerous conditions, such as hemorrhoids—including pain, itching, a lump or mass and changes in bowel movements—and as a result can go undetected leading to the majority of patients presenting with locally advanced disease.8,9 More information about SCAC is available by visiting www.analcancer.com.

About POD1UM

The POD1UM (PD1 Clinical Program in Multiple Malignancies) clinical trial program for retifanlimab includes POD1UM-303, POD1UM-202 and several other Phase 1, 2 and 3 studies for patients with solid tumors, including a registration-directed trial evaluating retifanlimab in combination with platinum-based chemotherapy for patients with non-small cell lung cancer.

About POD1UM-303/InterAACT 2

POD1UM-303/InterAACT 2 (NCT04472429) is a Phase 3, randomized, multicenter, double-blind, placebo-controlled study evaluating retifanlimab or placebo in combination with platinum-based chemotherapy (carboplatin and paclitaxel) in adult patients with inoperable locally recurrent or metastatic SCAC who have not been previously treated with systemic chemotherapy.

During the blinded portion of the study, patients, including those with well-controlled HIV infection, were randomized 1:1 to receive retifanlimab 500 mg intravenously or placebo during each 28-day cycle for up to 6 months in combination with standard therapy of carboplatin and paclitaxel, followed by retifanlimab or placebo monotherapy for up to 1-year total treatment in the absence of disease progression or unacceptable toxicity. Crossover to retifanlimab monotherapy was allowed for patients assigned to placebo upon verification of progression by blinded independent central review (BICR).

The primary endpoint was progression-free survival (PFS) as determined by BICR using RECIST v1.1. The key secondary endpoint was overall survival (OS). Other secondary endpoints include objective response rate (ORR), duration of response (DOR), disease control rate (DCR) by BICR, safety and pharmacokinetics.

Poster Presentation:

1. First Presentation of Efficacy and Safety Data for First-Line Treatment of CLL/SLL with BCL2 Inhibitor Mesutoclax in Combination with BTK Inhibitor Orelabrutinib (Abstract No.: PS1567)

The study showed that mesutoclax (100 and 125 mg) in combination with orelabrutinib was safe and well tolerated in patients with treatment naïve (TN) CLL/SLL. Substantial efficacy was observed, with early high undetectable MRD (uMRD) rate.

42 patients with TN CLL/SLL were enrolled (mesutoclax 100 mg, n=21; 125 mg, n=21). The fixed-duration treatment of mesutoclax in combination with orelabrutinib is expected to deliver deeper remissions for TN CLL/SLL patients. In all patients, the overall response rate (ORR) was 97.6%.

At week 24 of the combination therapy, in the 125 mg dose cohort, the overall response rate (ORR) was 100%, the complete remission rate (CRR) was 23.8%, the CRR in target lesions was 57.1%, and the peripheral blood (PB) uMRD rate was 48%. In the 100 mg mesutoclax dose cohort, the ORR was 95.2%, the CRR was 19.0%, the CRR in target lesions was 42.9%, and the PB uMRD rate was 19%. With the extension of the duration of treatment, the therapeutic efficacy is expected to be further improved.

All patients are still on treatment. No disease progression or death occurred, and no adverse events leading to discontinuation of treatment were reported.

Due to its favorable efficacy and safety profile, a registrational Phase III clinical study of mesutoclax (125 mg once daily) in combination with orelabrutinib for the treatment of TN CLL/SLL patients has been initiated, with patient enrollment being accelerated.

2. Orelabrutinib Combined with Bendamustine-Rituximab or Obinutuzumab followed by Orelabrutinib Maintenance in Untreated Marginal Zone Lymphoma (OPTIMIZE): A Multicenter, Single-Arm, Phase II Study (Abstract No.: PF898)

The absence of a standard first-line treatment for marginal zone lymphoma (MZL) have inspired the exploration of novel regimens. In recent years, Bruton’s tyrosine kinase inhibitors (BTKis) have demonstrated durable responses with a favorable benefit-risk profile across all MZL subtypes in the relapsed/refractory setting. Orelabrutinib is a novel BTK inhibitor with higher selectivity and fewer off-target than other BTK inhibitors. Orelabrutinib combined with bendamustine-rituximab or obinutuzumab followed by orelabrutinib maintenance was effective and well-tolerated in untreated patients with MZL.

The majority of patients presented with MALT lymphoma and had Ann Arbor stage II-IV disease. At the end of induction treatment, the overall response rate (ORR) was 100.0% among all enrolled patients. At the data cutoff, the median progression-free survival (PFS) and overall survival (OS) remained immature. No BTK inhibitor-related adverse events (AEs), such as atrial fibrillation or bleeding, were observed.

3. The Rationality, Efficacy and Safety of Orelabrutinib plus Obinutuzumab (O2) in Systemic Treatment-naïve Marginal Zone Lymphoma: A Prospective Cohort Study (Abstract No.: PS1902)

The Orelabrutinib plus Obinutuzumab regimen had well rationality and demonstrated promising efficacy.

Across the entire study and during the period of induction therapy, the best objective response rate (ORR) was 100%. 3 patients who achieved partial response (PR) after the induction therapy subsequently achieved complete response (CR) in the maintenance period. The 18-month progression-free survival (PFS) and overall survival (OS) rates were both 100%.

4. Ultra-low Dose Radiotherapy Combined with Orelabrutinib Improves the Complete Response Rate of Treatment for Localized Ocular Adnexal Extranodal Marginal Zone B-cell Lymphoma (Abstract No.: PS1901)

The combination of ultra-low dose radiotherapy and orelabrutinib in the treatment of ocular adnexal extranodal marginal zone lymphoma (OA-EMZL) not only improves the effectiveness of treatment but also significantly reduces the toxic effects of radiotherapy, providing a new approach for the treatment of localized OA-EMZL.

Of all the 17 patients who completed treatment, 16 patients achieved complete response (CR) and one patient achieved a partial response. Additionally, the lesions in the patients still undergoing treatment have shrunk compared to before treatment.

5. Orelabrutinib plus Bendamustine-Rituximab (OBR) versus Bendamustine-Rituximab (BR) in Transplant-ineligible, Intermediate- to High-risk Mantle Cell Lymphoma (MCL) (Abstract No.: PS1969)

This open-label, randomized, multi-center study aims to compare the efficacy and safety of Orelabrutinib plus Bendamustine-Rituximab versus Bendamustine-Rituximab in transplant-ineligible, intermediate- to high-risk mantle cell lymphoma (MCL) patients. Early data suggest that Orelabrutinib plus Bendamustine-Rituximab could reduce disease progression events compared to Bendamustine-Rituximab in high-risk MCL. Updated outcomes on efficacy, safety, and biomarker analysis will be reported.

6. Pomalidomide, Rituximab, Orelabrutinib, and MiniCHOP-like (PRO-miniCHOP) in Elderly Patients with Newly Diagnosed Diffuse Large B-cell Lymphoma: Updated Results from a Phase II Study (Abstract No.: PF950)

The results further support Pomalidomide, Rituximab, Orelabrutinib, and MiniCHOP-like (PRO-miniCHOP) as a potential treatment option for elderly patients with diffuse large B-cell lymphoma (DLBCL), demonstrating promising efficacy and acceptable safety, especially for those who responded to the Pomalidomide-Rituximab-Orelabrutinib (PRO) induction therapy.

A total of 32 patients were enrolled in this study, of whom 26 patients completed ≥3 cycles of the PRO-miniCHOP, resulting in a complete response rate (CRR) of 65.4% and overall response rate (ORR) of 100.0%. Among the 21 patients who completed the full 6-cycle therapy with PRO-miniCHOP, both the CRR and ORR were 95.2%. At a median follow-up of 15.6 months, the median progression-free survival (PFS) and overall survival (OS) had not yet been reached, with the 2-year PFS and OS rates being 94.7% and 100.0%, respectively.

7. Orelabrutinib Addition to R-CHOP-like Regimen Adapted to Response in Treatment-Naïve Non-GCB DLBCL: Update Results of Orient Study (Abstract No.: PS1943)

In non-germinal center B-cell-like (non-GCB) diffuse large B-cell lymphoma (DLBCL) patients who responded to orelabrutinib plus rituximab (OR) induction, orelabrutinib plus R-CHOP-like (OR-CHOP) exhibited favorable antitumor activity and manageable safety. Update results further support the orelabrutinib plus R-CHOP-like therapy as an option in this disease.

At end of 6-cycle orelabrutinib plus R-CHOP-like, response (all 100%) was independent of double-expressing lymphoma (DEL), extranodal involvement (EI), and Lymphgen subtypes. No off-target-related cardiac toxicities occurred.

8. Primary Efficacy and Safety of First-line R-MTO Regimen (Rituximab, Methotrexate, Thiotepa, and Orelabrutinib) followed by Autologous Hematopoietic Stem Cell Transplantation in PCNSL (Abstract No.: PF966)

The Rituximab, Methotrexate, Thiotepa, and Orelabrutinib (R-MTO) induction treatment has demonstrated notable efficacy in achieving higher response rate among patients with newly diagnosed primary central nervous system lymphoma (PCNSL), with a manageable safety profile.

At the data cutoff, all patients had completed four cycles of induction therapy, and the complete response (CR) rate and overall response rate (ORR) were 93.34% and 96.67%, respectively. The 12-month progression-free survival (PFS) and overall survival (OS) rates were 82.26% and 85.33%, respectively.

9. Orelabrutinib, Rituximab Combined with High-Dose Methotrexate as Induction Therapy in Newly Diagnosed Primary Central Nervous System Lymphoma (Abstract No.: PS1917)

This study demonstrated the promising efficacy of the Orelabrutinib, Rituximab Combined with High-Dose Methotrexate induction regimen in newly diagnosed primary central nervous system lymphoma (PCNSL), with encouraging response rates and durable progression-free survival (PFS). The regimen also showed promising overall survival (OS) trends, highlighting its potential as an effective treatment. Treatment-related adverse events (TRAEs) were manageable, and no severe BTK inhibitor-related off-target toxicities (e.g., atrial fibrillation/flutter) were observed. These findings suggest that the Orelabrutinib, Rituximab Combined with High-Dose Methotrexate regimen is a well-tolerated and effective therapeutic option for PCNSL.

Key findings:

A total of 251 newly diagnosed multiple myeloma patients were enrolled in 9 top-tier US cancer centers; this all-comers study allows for a broad and diverse patient population, mimicking the real-world setting.
Progression-Free Survival (PFS) showed a significant difference between the standard- and high-risk groups, while Overall Survival (OS) did not differ significantly based on conventional clinical risk markers.
Risk stratification by SKY92 showed significant differences in both survival PFS and OS endpoints:
– SKY92 standard-risk patients have a 3-year PFS and OS of 66% and 92% respectively
– SKY92 high-risk patients have a 3-year PFS and OS of 39% and 76% respectively
The study demonstrates that integrating SKY92 into routine practice can enhance prognostic accuracy and support personalized treatment planning, marking an important milestone toward the widespread clinical implementation of the SKY92 classifier in MM management. The PROMMIS study was made possible through the close collaboration of nine renowned U.S. hospitals and research centers. Together, these institutions enrolled 251 newly diagnosed multiple myeloma (NDMM) patients between 2018 and 2021. This broad representation underscores the generalizability of the study’s findings to clinical practice. The study prospectively confirmed that SKY92 significantly improves risk stratification over conventional clinical and genetic markers. Patients classified as high risk by SKY92 exhibited significantly shorter PFS and OS, validating the signature’s prognostic strength in real-world data.

After receiving SKY92 results, clinicians revised their initial hypothetical treatment plans in 50% of the cases. By accurately identifying high-risk patients, SKY92 supports more intensive or trial-based treatment approaches for those who need them. At the same time, by accurately identifying standard-risk patients, SKY92 can reduce the overestimation of risk in patients who may not require aggressive treatment, minimizing unnecessary toxicity associated with intensive therapy. The integration of SKY92 into clinical decision-making increased physician confidence in 40% of cases. Clinicians reported greater certainty and objectivity when interpreting complex risk profiles, leading to improved alignment of treatment with patient prognosis.

"These findings offer strong evidence that SKY92 can help clinicians better define high-risk multiple myeloma patients, enabling more targeted and appropriate therapeutic strategies," said Dr. Noa Biran, M.D., study investigator and Associate Professor at Hackensack Meridian School of Medicine.

"This publication confirms years of scientific work and collaboration," said Jvalini Dwarkasing, PhD, Chief Scientific Officer at SkylineDx. "The SKY92 signature brings molecular precision to the clinic, giving physicians a powerful tool to reduce uncertainty in a highly complex disease. It’s incredibly rewarding to see its positive impact on real-world patient care".

The results from the PROMMIS study underscore the powerful role SKY92 can play in modernizing risk stratification and guiding personalized treatment decisions for multiple myeloma patients. By providing molecular-level insights that outperform traditional risk assessment tools, SKY92 supports clinicians in delivering more precise, confident, and effective care. This study brings us one step closer to making precision medicine a standard in hematology and reaffirms SkylineDx’s commitment to improving patient outcomes through innovation in diagnostics.

About SKY92

Multiple Myeloma is a heterogeneous disease, and its course can vary significantly between patients. The SKY92 biomarker enhances biological insights into the disease. This molecular diagnostic test measures the activity of 92 genes in the malignant myeloma plasma cells and determines how aggressive the myeloma is. When myeloma is more aggressive (high-risk disease) it is less likely to respond to conventional treatments and the patient might benefit from intensification of therapy. The test is CE-IVD registered in Europe and available as laboratory developed test (LDT) from SkylineDx’s CAP/CLIA lab in San Diego (CA, USA).
