Identification and treatment of newly diagnosed patients with high-risk myeloma remains a global challenge. Diagnostically, there is currently an unmet need as high-risk patients could remain unidentified and experience an early relapse on standard of care treatment. Identifying aggressive disease correctly and early is therefore paramount for risk-stratified treatment approaches in myeloma.

The independent prospective multi-center UK OPTIMUM trial published in the Journal of Clinical Oncology by the UK collaborative trial group, offered patients from nearly 40 hospitals across the UK extended molecular risk screening over standard of care, by combining SKY92 with standard genetic testing for two or more high-risk markers, also termed Ultra high-risk MM (UHRMM). Patients identified as having UHRMM by either marker, or those with plasma cell leukemia (PCL), were offered intensified treatment with Dara-CVRd before and for 18 cycles after autologous stem cell transplant (ASCT). In this unique prospective molecular screening and treatment trial, SKY92 identified about 10% of NDMM patients with UHRMM who otherwise could not be identified with standard of care genetic risk markers, and vice versa, confirming prior retrospective results [2]. These patients would have effectively been missed with traditional diagnostics methods alone. In addition, the majority of PCL patients were identified by SKY92, suggesting that a wider aggressive group of disease could be diagnosed with this test in the future. Importantly, outcome of UHRMM patients treated with intensified Dara-CVRd in OPTIMUM was markedly improved over that of a digital comparator group of trial patients identified by SKY92 or standard of care genetics from the UK Myeloma XI trial: at 30 months, progression free survival (PFS) was 77% in OPTIMUM vs. 39.8% for Myeloma XI treatment. This Myeloma XI treatment is similar to standard of care. At 30 months follow up, the overall survival (OS) rate was 83.5%, vs. 73.5% using the conventional method.

"Everyone recognizes that myeloma is a highly heterogeneous disease and we now see, for the first time, markedly improved outcomes for the patients with highest unmet need, those with high-risk myeloma, with new treatment combinations. However, if we want to help and direct patients toward their best possible treatment options, we urgently need access to better molecular diagnostics as well. The sense that we are currently missing patients with aggressive disease at diagnosis is very real and confirmed by both retrospective and, with OPTIMUM, prospective evidence," said Dr. Martin F. Kaiser, Consultant Hematologist at The Institute of Cancer Research; Royal Marsden Hospital Sutton, England, United Kingdom.

"Dr. Kaiser set up a unique and innovative study design focused on a patient group in high need of new treatment strategies. The initial results, showing improved PFS and OS for the UHRMM, is an important step towards personalized treatment protocols," said Jvalini Dwarkasing, Chief Scientific Officer at SkylineDx. "We are appreciative that our SKY92 test was able to support this study by identifying UHRMM patients, indicating its utility in clinical application."

About MMprofiler with SKY92

The clinical course of MM can vary significantly between patients. This variability is related to unique characteristics of each patient’s disease. There are many treatment options available, in numerous combinations. Choosing the right treatment at the right time, while planning for future lines, is essential and can be very challenging. MMprofiler with SKY92 helps navigating these complexities. SKY92 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. MMprofiler with SKY92 is CE-IVD registered in Europe and available as laboratory developed test (LDT) from SkylineDx’s CAP/CLIA lab in San Diego (CA, USA).

"This financing round is a significant milestone. We appear to be the only company that has dissociated IL-2 potency from toxicity," said Dr. John Mumm, CEO of Deka. "It is gratifying to be supported by investors who recognize the potential of our innovative science to radically improve immunotherapy treatments by evaluating each patient’s immune system and combining biology with the power of precision medicine.

We have only raised $55 million to date and are already proceeding to dose our third cohort in our Phase 1 clinical trial. Thus far, we have established safety and clear signs of immune activation in our first 2 cohorts. We are encouraged by these results and believe that this combined approach will result in safer, more efficacious, and cost-effective immunotherapies."

"Deka’s unique vision of rationally combining multiple cytokines in a single therapeutic, and the potential impact this could have for patients suffering from cancer and autoimmunity, was deeply intriguing to the MPM BioImpact team," said Dr. Detlev Biniszkiewicz, Managing Director at MPM BioImpact. "We are impressed by the ability of DK210 to improve the safety parameters of IL-2 while maintaining potent anti-tumor responses in cancer patients, and we are thrilled to be working with the Deka team in developing their innovative approach."

The funding follows the seed round investment of USD $5 million led by CEO John Mumm, Series A financing of USD $20 million announced in November 2021, co-led by Leaps by Bayer and ECHO Investment Capital, and a USD $21.5 million Series B1 co-led by Lumira and Leaps by Bayer in 2022. The previous financings have enabled Deka to advance a pipeline of multiple DiakinesTM, conduct critical IND enabling experiments, manufacture drug substance/drug product with Cytovance Biologics, start the first Phase I clinical trial, as well as to expand into a new facility.

Landmark Phase 3 MARIPOSA Study Meets Primary Endpoint Resulting in Statistically Significant and Clinically Meaningful Improvement in Progression-Free Survival for RYBREVANT® (amivantamab-vmjw) plus Lazertinib Versus Osimertinib in Patients with EGFR-Mutated Non-Small Cell Lung Cancer

On September 28, 2023 The Janssen Pharmaceutical Companies of Johnson & Johnson reported positive topline results from the Phase 3 MARIPOSA study evaluating RYBREVANT (amivantamab-vmjw), a bispecific antibody targeting epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition (MET), in combination with lazertinib, an oral third-generation EGFR tyrosine kinase inhibitor (TKI), versus osimertinib as first-line treatment in patients with locally advanced or metastatic EGFR-mutated non-small cell lung cancer (NSCLC) (Press release, Johnson & Johnson, SEP 28, 2023, View Source;301941646.html [SID1234635512]).

The pivotal Phase 3 MARIPOSA study met its primary endpoint with a statistically significant and clinically meaningful improvement in progression-free survival (PFS) in patients receiving RYBREVANT plus lazertinib compared to osimertinib. The combination of RYBREVANT and lazertinib demonstrated a safety profile consistent with previously reported data on the combination. A planned interim overall survival (OS) analysis showed a trend favoring the combination of RYBREVANT and lazertinib compared to osimertinib. Patients in the study will be followed for subsequent OS analyses, which will determine the statistical and clinical significance of OS.1*

"Positive topline results from the MARIPOSA study reinforce the potential of the RYBREVANT and lazertinib combination in frontline EGFR-mutated non-small cell lung cancer as a future standard of care," said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. "As a combination targeted regimen, RYBREVANT and lazertinib inhibit critical oncogenic driver pathways and activate the immune system to address disease in multiple ways."

"Patients with treatment-naïve EGFR-mutated non-small cell lung cancer have historically been treated with EGFR TKIs, but these agents invariably lead to resistance and disease progression when used as monotherapy," said Alexander Spira†, M.D., Ph.D., FACP, Director, Virginia Cancer Specialists Research Institute, and study investigator. "These promising data from MARIPOSA underscore the potential for the RYBREVANT and lazertinib regimen to advance treatment beyond TKI monotherapy."

MARIPOSA (NCT04487080), which enrolled 1,074 patients, is a randomized, open-label Phase 3 study evaluating RYBREVANT in combination with lazertinib versus osimertinib and versus lazertinib alone in first-line treatment of patients with locally advanced or metastatic NSCLC with EGFR exon 19 deletions (ex19del) or substitution mutations. The primary endpoint of the study is PFS (using RECIST v1.1 guidelines‡) as assessed by blinded independent central review. Secondary endpoints include OS, objective response rate (ORR), duration of response (DoR), intracranial PFS, PFS after first subsequent therapy (PFS2) and time to symptomatic progression.1

MARIPOSA marks the third RYBREVANT Phase 3 study to readout this year following PAPILLON and MARIPOSA-2. Janssen plans to submit these results for presentation at an upcoming scientific congress, including additional details on select secondary endpoints.

About RYBREVANT
RYBREVANT (amivantamab-vmjw), a fully-human bispecific antibody targeting EGFR and MET with immune cell-directing activity, received accelerated approval by the U.S. Food and Drug Administration (FDA) in May 2021 for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.2 This indication is approved under accelerated approval based on ORR and DoR. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. RYBREVANT has also received approval from health authorities in Europe, as well as other markets around the world.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non-Small Cell Lung Cancer§ prefer next-generation sequencing-based strategies over polymerase chain reaction-based approaches for the detection of EGFR exon 20 insertion variants, and include amivantamab-vmjw (RYBREVANT) as a subsequent therapy option with a Category 2A recommendation for patients that have progressed on or after platinum-based chemotherapy with or without immunotherapy and have EGFR exon 20 insertion mutation-positive advanced NSCLC.3‖¶

In addition to the Phase 3 MARIPOSA study, RYBREVANT is being studied in multiple clinical trials in NSCLC, including:

The Phase 3 MARIPOSA-2 (NCT04988295) study assessing the efficacy of RYBREVANT (with or without lazertinib) and carboplatin-pemetrexed versus carboplatin-pemetrexed in patients with locally advanced or metastatic EGFR ex19del or L858R substitution NSCLC after disease progression on or after osimertinib. Topline data for this randomized Phase 3 study demonstrated statistically significant and clinically meaningful improvement in PFS in patients receiving RYBREVANT plus chemotherapy with and without lazertinib versus chemotherapy.4
The Phase 3 PAPILLON (NCT04538664) study assessing RYBREVANT in combination with carboplatin-pemetrexed versus chemotherapy alone in the first-line treatment of patients with advanced or metastatic NSCLC with EGFR exon 20 insertion mutations. Topline data for this randomized Phase 3 study demonstrated statistically significant and clinically meaningful improvement in PFS in patients receiving RYBREVANT.5
The Phase 1 CHRYSALIS (NCT02609776) study evaluating RYBREVANT in participants with advanced NSCLC.6
The Phase 1/1b CHRYSALIS-2 (NCT04077463) study evaluating RYBREVANT in combination with lazertinib and lazertinib as a monotherapy in patients with advanced NSCLC with EGFR mutations.7
The Phase 1 PALOMA (NCT04606381) study assessing the feasibility of subcutaneous (SC) administration of amivantamab based on safety and pharmacokinetics and to determine a dose, dose regimen and formulation for amivantamab SC delivery.8
The Phase 2 PALOMA-2 (NCT05498428) study assessing subcutaneous amivantamab in participants with advanced or metastatic solid tumors including EGFR-mutated NSCLC.9
The Phase 3 PALOMA-3 (NCT05388669) study assessing lazertinib with subcutaneous amivantamab compared to intravenous amivantamab in participants with EGFR-mutated advanced or metastatic NSCLC.10
The Phase 1/2 METalmark (NCT05488314) study assessing RYBREVANT and capmatinib combination therapy in locally advanced or metastatic NSCLC.11
The Phase 1/2 PolyDamas (NCT05908734) study assessing RYBREVANT and cetrelimab combination therapy in locally advanced or metastatic NSCLC.12
The Phase 2 SKIPPirr study (NCT05663866) exploring how to decrease the incidence and/or severity of first-dose infusion-related reactions with RYBREVANT in combination with lazertinib in relapsed or refractory EGFR-mutated advanced or metastatic NSCLC.13

About Lazertinib
Lazertinib is an oral, third-generation, brain-penetrant EGFR TKI that targets both the T790M mutation and activating EGFR mutations while sparing wild type-EGFR. An analysis of the efficacy and safety of lazertinib from the Phase 3 LASER301 (NCT04248829) study was published in The Journal of Clinical Oncology in 2023 and demonstrated lazertinib improved PFS compared to the first generation EGFR TKI gefitinib in all prespecified subgroups, including Asian patients, those with L858R mutations and those with a history of brain metastases.14 In 2018, Janssen Biotech, Inc., entered into a license and collaboration agreement with Yuhan Corporation for the development of lazertinib.

About Non-Small Cell Lung Cancer
Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.15,16 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma and large cell carcinoma.17 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.18 EGFR mutations are present in 10 to 15 percent of Western patients with NSCLC with adenocarcinoma histology and occur in 40 to 50 percent of Asian patients. 17,18,19,20,21,22 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.23 The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR TKIs is less than 20 percent.24,25 Patients with EGFR ex19del or L858R mutations have a real-world five-year OS of 19 percent.26

RYBREVANT IMPORTANT SAFETY INFORMATION2

WARNINGS AND PRECAUTIONS  

Infusion-Related Reactions
RYBREVANT can cause infusion-related reactions (IRR); signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting.

Based on the safety population, IRR occurred in 66% of patients treated with RYBREVANT. Among patients receiving treatment on Week 1 Day 1, 65% experienced an IRR, while the incidence of IRR was 3.4% with the Day 2 infusion, 0.4% with the Week 2 infusion, and cumulatively 1.1% with subsequent infusions. Of the reported IRRs, 97% were Grade 1-2, 2.2% were Grade 3, and 0.4% were Grade 4. The median time to onset was 1 hour (range 0.1 to 18 hours) after start of infusion. The incidence of infusion modifications due to IRR was 62% and 1.3% of patients permanently discontinued RYBREVANT due to IRR.

Premedicate with antihistamines, antipyretics, and glucocorticoids and infuse RYBREVANT as recommended. Administer RYBREVANT via a peripheral line on Week 1 and Week 2. Monitor patients for any signs and symptoms of infusion reactions during RYBREVANT infusion in a setting where cardiopulmonary resuscitation medication and equipment are available. Interrupt infusion if IRR is suspected. Reduce the infusion rate or permanently discontinue RYBREVANT based on severity.
