DARZALEX FASPRO® (daratumumab and hyaluronidase-fihj)-based regimen shows 95 percent progression-free survival at four years in transplant-eligible, newly diagnosed patients with multiple myeloma who achieved sustained MRD negativity

On June 3, 2025 Johnson & Johnson (NYSE: JNJ) reported data from two studies highlighting that a DARZALEX FASPRO (daratumumab and hyaluronidase-fihj)-based quadruplet regimen demonstrated deep and sustained minimal residual disease (MRD) negativity rates, and improved long-term progression-free survival (PFS) in patients with newly diagnosed multiple myeloma (NDMM), regardless of transplant status (Press release, Johnson & Johnson, JUN 3, 2025, View Source [SID1234653686]). Findings were highlighted as oral presentations of an analysis of sustained MRD in transplant-eligible patients from the Phase 3 PERSEUS study (Abstract #7501) and a subgroup analysis of transplant-ineligible patients in the Phase 3 CEPHEUS study (Abstract #7516) at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.

New analysis from the Phase 3 PERSEUS study shows the addition of DARZALEX FASPRO to bortezomib, lenalidomide and dexamethasone (D-VRd), followed by an investigational maintenance regimen of DARZALEX FASPRO with lenalidomide (D-R), led to improved and deepened rates of overall and sustained MRD negativity (10-5), defined as no cancer cells detected within 100,000 bone marrow cells) for at least 24 months, compared to VRd induction and consolidation with R maintenance. More than half of patients who received the DARZALEX FASPRO-based regimen achieved sustained MRD negativity for 24 or more months and more than two-thirds of patients achieved sustained MRD-negativity at 12-months, showing 95.3 percent PFS at 48-months (95 percent confidence interval [CI], 0.3-2.3)—reinforcing the ability of DARZALEX FASPRO to delay disease progression or death.1

"The data show that D-VRd followed by an investigational D-R maintenance regimen is a highly effective treatment option for transplant-eligible patients with newly diagnosed multiple myeloma," said Philippe Moreau*, M.D., head of the Hematology Department, University Hospital Hôtel-Dieu, Nantes, France and presenting author. "The depth and durability of MRD negativity observed—paired with unprecedented progression-free survival at four years—underscore the long-term benefit the DARZALEX FASPRO-based regimen can offer patients early in their treatment journey."

At a median follow-up of 47.5 months, 24-month sustained MRD negativity rates at the 10⁻⁵ sensitivity threshold were more than double with D-VRd followed by investigational D-R maintenance (55.8 percent), compared to VRd followed by R maintenance (22.6 percent) (odds ratio [OR]=4.36; 95 percent CI, 3.15-6.05; P<0.0001). Similarly, MRD negativity at 12 months was higher with D-VRd and D-R maintenance at 64.8 percent compared to VRd and R maintenance (29.7 percent) (OR=4.42, 95 percent CI, 3.22-6.08, P<0.0001).1

Additional data from Phase 3 CEPHEUS study explore the benefits of DARZALEX FASPRO in transplant-ineligible patients across cytogenetic risk status

The post-hoc analysis of the Phase 3 CEPHEUS study focused exclusively on transplant-ineligible patients, reinforcing that adding DARZALEX FASPRO to VRd significantly deepens response and prolongs PFS compared to VRd alone, even in patients who are older and considered frail by the Myeloma Geriatric Assessment score.

At a median follow-up of 58.7 months, patients receiving D-VRd achieved markedly higher overall MRD negativity rates at the 10⁻⁵ sensitivity threshold with 60.4 percent versus 39.3 percent with VRd (OR 2.37; 95 percent CI, 1.47–3.80; P=0.0004). Furthermore, treatment with D-VRd resulted in high MRD-negativity rates at the 10⁻⁶ threshold (no cancer cells detected within 1,000,000 bone marrow cells) with 45.8 percent compared to 26.9 percent with VRd (OR 2.28; 95 percent CI, 1.40–3.73; P=0.0010). These deeper responses translated into improved long-term outcomes, with 69 percent of patients remaining progression free at 54-months when treated with D-VRd versus 48.0 percent with VRd (hazard ratio [HR] 0.51; 95 percent CI, 0.35–0.74). Overall survival (OS) numerically favored D-VRd (HR 0.66; 95 percent CI, 0.42–1.03), with an even greater benefit observed after censoring for COVID-19-related deaths (HR 0.55; 95 percent CI, 0.34–0.90).2

Additional data presented at ASCO (Free ASCO Whitepaper) included a subgroup analysis of the CEPHEUS trial for both transplant-ineligible and deferred NDMM patients who were considered high-risk for cytogenetic abnormalities (Abstract #7529). At a median follow-up of 58.7 months, overall MRD negativity rate was improved for patients with standard risk in D-VRd versus VRd. Rates by treatment arm in patients at high risk were comparable.3

"Across multiple studies, the growing body of data on DARZALEX-based regimens indicates impressive, deep responses and meaningful progression-free survival in patients with newly diagnosed multiple myeloma, including high risk," Jordan Schecter, MD, Vice President, Disease Area Leader, Multiple Myeloma, Johnson & Johnson Innovative Medicine. "These consistent results across patient populations, regardless of transplant eligibility, reinforce the role of DARZALEX FASPRO as a cornerstone of frontline therapy."

In the PERSEUS and CEPHEUS studies, the safety profiles were consistent with the known safety profile for DARZALEX FASPRO.

About the PERSEUS Study
The PERSEUS study is being conducted in collaboration with the European Myeloma Network as the sponsor. PERSEUS is an ongoing, randomized, open-label, Phase 3 study comparing the efficacy and safety of D-VRd during induction and consolidation versus VRd during induction and consolidation in patients with NDMM eligible for ASCT. Following consolidation, patients received an investigational treatment regimen for maintenance that included DARZALEX FASPRO in combination with lenalidomide or lenalidomide alone. The trial was not designed to isolate the effect of DARZALEX FASPRO in the maintenance phase of treatment. The efficacy of DARZALEX FASPRO in combination with lenalidomide for maintenance has not been established. The primary endpoint is PFS, and secondary endpoints include overall CR or better rate, and overall MRD-negativity (in patients with CR or better). The median age is 61.0 (range, 32-70) years for patients in the D-VRd arm and 59.0 (range, 31-70) years for patients in the VRd arm.2 The study is being conducted in 14 countries in Europe and Australia.

About the CEPHEUS Study
CEPHEUS (NCT03652064) is an ongoing, multicenter, randomized, open-label, Phase 3 study comparing the efficacy and safety of D-VRd versus VRd in patients with newly diagnosed multiple myeloma who are transplant-ineligible or for whom transplant is not intended as initial therapy. Primary endpoint is overall MRD negativity rate at 10-5 sensitivity threshold. Secondary endpoints include CR or better rates, PFS, sustained MRD negativity rates for ≥12 months, MRD-negative rate at one year, overall response rates, time to and duration of response, PFS on next line of therapy, overall survival and safety. The trial has enrolled 396 patients in 13 countries.

About Multiple Myeloma
Multiple myeloma (MM) is a blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.4 In multiple myeloma, these malignant plasma cells proliferate and replace normal cells in the bone marrow.5 Multiple myeloma is the second most common blood cancer worldwide and remains an incurable disease.6 In 2024, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 will die from the disease.7 People with multiple myeloma have a 5-year survival rate of 59.8 percent. While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, kidney problems or infections.8,9

About DARZALEX FASPRO and DARZALEX
DARZALEX FASPRO (daratumumab and hyaluronidase-fihj) received U.S. FDA approval in May 2020 and is approved for nine indications in MM, four of which are for frontline treatment in newly diagnosed patients who are transplant-eligible or ineligible.3,6 It is the only subcutaneous CD38-directed antibody approved to treat patients with MM. DARZALEX FASPRO is co-formulated with recombinant human hyaluronidase PH20, Halozyme’s ENHANZE drug delivery technology.

DARZALEX (daratumumab) received U.S. FDA approval in November 2015 and is approved in eight indications, three of which are in the frontline setting, including newly diagnosed patients who are transplant-eligible and ineligible.9

DARZALEX is the first CD38-directed antibody approved to treat MM.9 DARZALEX-based regimens have been used in the treatment of more than 618,000 patients worldwide.

IMPORTANT SAFETY INFORMATION  

CONTRAINDICATIONS    
DARZALEX FASPRO is contraindicated in patients with a history of severe hypersensitivity to daratumumab, hyaluronidase, or any of the components of the formulation.    

WARNINGS AND PRECAUTIONS    

Hypersensitivity and Other Administration Reactions    
Both systemic administration-related reactions, including severe or life-threatening reactions, and local injection-site reactions can occur with DARZALEX FASPRO. Fatal reactions have been reported with daratumumab-containing products, including DARZALEX FASPRO.   

Systemic Reactions    
In a pooled safety population of 1249 patients with MM (N=1056) or light chain (AL) amyloidosis (N=193) who received DARZALEX FASPRO as monotherapy or in combination, 7 percent of patients experienced a systemic administration-related reaction (Grade 2: 3.2 percent, Grade 3: 0.7 percent, Grade 4: 0.1 percent). Systemic administration-related reactions occurred in 7 of patients with the first injection, 0.2 percent with the second injection, and cumulatively 1 percent with subsequent injections. The median time to onset was 2.9 hours (range: 5 minutes to 3.5 days). Of the 165 systemic administration-related reactions that occurred in 93 patients, 144 (87 percent) occurred on the day of DARZALEX FASPRO administration. Delayed systemic administration-related reactions have occurred in 1 percent of the patients. 

Severe reactions included hypoxia, dyspnea, hypertension, tachycardia, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Other signs and symptoms of systemic administration-related reactions may include respiratory symptoms, such as bronchospasm, nasal congestion, cough, throat irritation, allergic rhinitis, and wheezing, as well as anaphylactic reaction, pyrexia, chest pain, pruritus, chills, vomiting, nausea, hypotension, and blurred vision.    

Pre-medicate patients with histamine-1 receptor antagonist, acetaminophen, and corticosteroids. Monitor patients for systemic administration-related reactions, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) administration-related reactions, immediately and permanently discontinue DARZALEX FASPRO. Consider administering corticosteroids and other medications after the administration of DARZALEX FASPRO depending on dosing regimen and medical history to minimize the risk of delayed (defined as occurring the day after administration) systemic administration-related reactions.    

Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with daratumumab-containing products. If ocular symptoms occur, interrupt DARZALEX FASPRO and seek immediate ophthalmologic evaluation prior to restarting DARZALEX FASPRO.    

Local Reactions    
In this pooled safety population, injection-site reactions occurred in 7 percent of patients, including Grade 2 reactions in 0.8 percent. The most frequent (>1 percent) injection-site reaction was injection-site erythema. These local reactions occurred a median of 5 minutes (range: 0 minutes to 6.5 days) after starting administration of DARZALEX FASPRO. Monitor for local reactions and consider symptomatic management.    

Neutropenia    
Daratumumab may increase neutropenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX FASPRO until recovery of neutrophils. In lower body weight patients receiving DARZALEX FASPRO, higher rates of Grade 3-4 neutropenia were observed.    

Thrombocytopenia    
Daratumumab may increase thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Consider withholding DARZALEX FASPRO until recovery of platelets.    

Embryo-Fetal Toxicity    
Based on the mechanism of action, DARZALEX FASPRO can cause fetal harm when administered to a pregnant woman. DARZALEX FASPRO may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX FASPRO and for 3 months after the last dose.    

The combination of DARZALEX FASPRO with lenalidomide, thalidomide, or pomalidomide is contraindicated in pregnant women because lenalidomide, thalidomide, and pomalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, thalidomide, or pomalidomide prescribing information on use during pregnancy.    

Interference With Serological Testing    
Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive indirect antiglobulin test (indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab administration. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient’s serum. The determination of a patient’s ABO and Rh blood type are not impacted.    

Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX FASPRO. Type and screen patients prior to starting DARZALEX FASPRO.    

Interference With Determination of Complete Response    
Daratumumab is a human immunoglobulin G (IgG) kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some DARZALEX FASPRO-treated patients with IgG kappa myeloma protein.    

ADVERSE REACTIONS    

In MM, the most common adverse reaction (≥20 percent) with DARZALEX FASPRO monotherapy is upper respiratory tract infection. The most common adverse reactions with combination therapy (≥20 percent for any combination) include fatigue, nausea, diarrhea, dyspnea, insomnia, headache, pyrexia, cough, muscle spasms, back pain, vomiting, hypertension, upper respiratory tract infection, peripheral sensory neuropathy, constipation, pneumonia, and peripheral edema.    

The most common hematology laboratory abnormalities (≥40 percent) with DARZALEX FASPRO are decreased leukocytes, decreased lymphocytes, decreased neutrophils, decreased platelets, and decreased hemoglobin.

CONTRAINDICATIONS

DARZALEX is contraindicated in patients with a history of severe hypersensitivity (eg, anaphylactic reactions) to daratumumab or any of the components of the formulation.  

WARNINGS AND PRECAUTIONS  

Infusion-Related Reactions  

DARZALEX can cause severe and/or serious infusion-related reactions including anaphylactic reactions. These reactions can be life-threatening, and fatal outcomes have been reported. In clinical trials (monotherapy and combination: N=2066), infusion-related reactions occurred in 37 percent of patients with the Week 1 (16 mg/kg) infusion, 2 percent with the Week 2 infusion, and cumulatively 6 percent with subsequent infusions. Less than 1 percent of patients had a Grade 3/4 infusion-related reaction at Week 2 or subsequent infusions. The median time to onset was 1.5 hours (range: 0 to 73 hours). Nearly all reactions occurred during infusion or within 4 hours of completing DARZALEX. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia, headache, laryngeal edema, pulmonary edema, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting, and nausea. Less common signs and symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, hypotension and blurred vision.

When DARZALEX dosing was interrupted in the setting of ASCT (CASSIOPEIA) for a median of 3.75 months (range: 2.4 to 6.9 months), upon re-initiation of DARZALEX, the incidence of infusion-related reactions was 11 percent for the first infusion following ASCT. Infusion-related reactions occurring at re-initiation of DARZALEX following ASCT were consistent in terms of symptoms and severity (Grade 3 or 4: <1 percent) with those reported in previous studies at Week 2 or subsequent infusions. In EQUULEUS, patients receiving combination treatment (n=97) were administered the first 16 mg/kg dose at Week 1 split over two days, ie, 8 mg/kg on Day 1 and Day 2, respectively. The incidence of any grade infusion-related reactions was 42 percent, with 36 percent of patients experiencing infusion-related reactions on Day 1 of Week 1, 4 percent on Day 2 of Week 1, and 8 percent with subsequent infusions.

Pre-medicate patients with antihistamines, antipyretics, and corticosteroids.

Frequently monitor patients during the entire infusion. Interrupt DARZALEX infusion for reactions of any severity and institute medical management as needed. Permanently discontinue DARZALEX therapy if an anaphylactic reaction or life-threatening (Grade 4) reaction occurs and institute appropriate emergency care. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion.

To reduce the risk of delayed infusion-related reactions, administer oral corticosteroids to all patients following DARZALEX infusions. Patients with a history of chronic obstructive pulmonary disease may require additional post-infusion medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease.

Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with DARZALEX infusion. If ocular symptoms occur, interrupt DARZALEX infusion and seek immediate ophthalmologic evaluation prior to restarting DARZALEX.

Interference With Serological Testing  

Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive indirect antiglobulin test (indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab infusion. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient’s serum. The determination of a patient’s ABO and Rh blood type is not impacted. Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX. Type and screen patients prior to starting DARZALEX.

Neutropenia and Thrombocytopenia  

DARZALEX may increase neutropenia and thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX until recovery of neutrophils or for recovery of platelets.

Interference With Determination of Complete Response  

Daratumumab is a human immunoglobulin G (IgG) kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.

Embryo-Fetal Toxicity  

Based on the mechanism of action, DARZALEX can cause fetal harm when administered to a pregnant woman. DARZALEX may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX and for 3 months after the last dose.

The combination of DARZALEX with lenalidomide, pomalidomide, or thalidomide is contraindicated in pregnant women because lenalidomide, pomalidomide, and thalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, pomalidomide, or thalidomide prescribing information on use during pregnancy.

ADVERSE REACTIONS  

The most frequently reported adverse reactions (incidence ≥20 percent) were: upper respiratory infection, neutropenia, infusion related reactions, thrombocytopenia, diarrhea, constipation, anemia, peripheral sensory neuropathy, fatigue, peripheral edema, nausea, cough, pyrexia, dyspnea, and asthenia. The most common hematologic laboratory abnormalities (≥40 percent) with DARZALEX are: neutropenia, lymphopenia, thrombocytopenia, leukopenia, and anemia.

Experimental Drug Development Centre Announces the Presentation of Updated Data from the Phase 1 Study of Antibody-Drug Conjugate EBC-129 at the 2025 Annual Meeting of the American Society of Clinical Oncology (ASCO)

On June 3, 2025 The Experimental Drug Development Centre (EDDC), Singapore’s national platform for drug discovery and development, reported the presentation of updated clinical data for the ongoing Phase 1 trial for EBC-129 at the 2025 Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in Chicago (Press release, Experimental Drug Development Centre, JUN 3, 2025, View Source [SID1234653702]).

EBC-129 is a first-in-class antibody drug conjugate (ADC) targeting a novel, tumour-specific N256-glycosylated epitope on CEACAM5 and CEACAM6. The updated findings showed promising efficacy data from 21 heavily pre-treated pancreatic ductal adenocarcinoma (PDAC) patients across the dose escalation and the dose expansion portions of the Phase 1 study. Patients received EBC-129 at doses between 1.8 and 2.2 mg/kg, given once every 3 weeks. 17 out of 21 patients (81%) of the patients had received prior treatment with taxanes. 82% of patients had tumours which expressed the EBC-129 antigen at ≥1% at 3+ intensity and were therefore considered treatable. The overall response rates (ORRs) were 25% and 20%, with disease control rates (DCRs) of 87.5% and 63.6% and progression-free survival (PFS) of 19 and 12 weeks for 1.8 mg/kg and 2.2 mg/kg, respectively.

"Pancreatic adenocarcinoma remains one of the most challenging cancers to treat, particularly in the metastatic setting where resistance to standard therapies is common. The clinical signals observed with EBC-129 in refractory pancreatic adenocarcinoma, including tolerability, prolonged disease control and a confirmed response in a heavily pre-treated patient, are encouraging and clinically meaningful. Continued prioritisation of biology-guided trials targeting EBC-129 will be key to sustaining momentum in this important therapeutic effort," said Assistant Professor Robert W. Lentz, MD, Division of Medical Oncology, Department of Medicine, University of Colorado Anschutz School of Medicine.

This presentation follows the recent Fast Track Designation granted by the U.S. FDA for EBC-129 in the treatment of PDAC patients. This designation supports EDDC’s efforts to accelerate the advancement of the programme through increased regulatory engagement and the potential for expedited review pathways.

Other Results to Date

The dose escalation study of the Phase 1 trial was open to all patients, while the ongoing dose expansion study comprises of three cohorts in PDAC, gastroesophageal adenocarcinoma (GEA) and tumour-agnostic patients with other immunohistochemistry (IHC)-positive solid tumours. Recruitment for the GEA and IHC-positive cohorts is still ongoing.

EBC-129 showed a manageable safety profile in the 58 patients treated so far, with uncomplicated neutropenia and infusion-related reactions as the main treatment-related adverse events (TRAEs) observed.

The EBC-129 antigen was also found to be highly expressed, with 52% to 100% of tumour tissues assessed during the trial showing moderate to high expression levels of ≥20% at 2+ and/or 3+. This included samples from gastroesophageal, appendiceal, colorectal and lung cancer patients, making EBC-129 a potentially viable treatment option for these cancers.

"We have seen encouraging signs of efficacy of EBC-129 as a single-agent therapy, even in heavily pre-treated patients with metastatic pancreatic cancer. This, combined with the observed safety profile, underscores the promise of EBC-129 as a possible treatment option for PDAC patients. As a first-in-class ADC that targets both CEACAM5 and CEACAM6, EBC-129 has also shown potential against a range of other solid tumours, and we look forward to expanding clinical evaluations with the ongoing dose expansion cohorts and accelerating the development of EBC-129 to address critical unmet needs in cancer," said Professor Damian O’Connell, CEO of EDDC.

About EBC-129

EBC-129 is an ADC that targets a tumour-specific N256-glycosylation site conserved on CEACAM5 and CEACAM6. CEACAM5 and CEACAM6 are known to have functional importance in tumour formation, migration and metastasis. In the ongoing trial, the tumour-specific marker is found to be widely expressed in multiple solid tumour types, including gastric, oesophageal, pancreatic, lung, colorectal, and appendiceal cancers, based on an analytically validated immunohistochemistry (IHC) assay. The payload used in EBC-129 is monomethyl auristatin E (MMAE), which has been extensively tested and approved for clinical use in other marketed ADCs, and has demonstrated synergy with PD-1 inhibitors. The ongoing Phase 1 trial of EBC-129 is assessing the safety and tolerability of EBC-129 as a single agent and in combination with pembrolizumab in patients with advanced solid tumours. Enrolment for the PDAC cohort in the Phase 1 dose expansion study is now complete, while recruitment continues for the gastroesophageal adenocarcinoma (GEA) and IHC-positive cohorts.

Michael Bailey, president and Chief Executive Officer, stated, "We were really excited to present these three posters at this year’s ASCO (Free ASCO Whitepaper) annual meeting, which we believe further showcase the use of tivozanib after frontline ICI-based combination therapy, but also AVEO’s pipeline which is focused on developing therapies that improve the lives of patients with cancer."

Poster title: "Efficacy of second line (2L) treatment with tivozanib (Tivo) as monotherapy or with nivolumab (Nivo) in patients (pts) with metastatic renal cell carcinoma (mRCC) previously treated with an immune checkpoint inhibitor (ICI) combination of ipilimumab (Ipi)/Nivo or vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFR-TKI)/ICI in the Phase 3 TiNivo-2 study." – (Abstract: 4540; Poster: 340)

AVEO presented data from an exploratory sub-analysis of the TiNivo-2 study, evaluating the efficacy of tivozanib as a 2nd line treatment option in patients who failed 1st line vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) and immune checkpoint inhibitor combination therapy. The subgroup analysis indicates that tivozanib monotherapy at 1.34mg daily showed activity, including substantial tumor size reduction, in patients who previously received a contemporary 1st line metastatic renal cell carcinoma (mRCC) treatment regimen. Additionally, the sub-analysis showed no benefit in the addition of nivolumab to tivozanib in this context, akin to the results of the parent TiNivo-2 trial.

Poster Title: "FIERCE-HN: A multicenter, randomized, double-blind, placebo-controlled, phase 3 study of ficlatuzumab (HGF/cMET Mab) in combination with cetuximab in participants with recurrent or metastatic (R/M) HPV negative head and neck squamous cell carcinoma (HNSCC)."– (Abstract: TPS6115; Poster: 520a)

AVEO presented a trial in progress poster for the Phase 3 FIERCE-HN trial, which is evaluating the combination of ficlatuzumab and cetuximab in patients with recurrent or metastatic (R/M) HPV-negative head and neck squamous cell carcinoma (HNSCC). The purpose of this study is to evaluate the efficacy and safety of ficlatuzumab (10 or 20 mg/kg) in combination with cetuximab (500 mg/kg) against placebo plus cetuximab in participants with HPV-negative R/M HNSCC. The study is evaluating whether ficlatuzumab combined with cetuximab is superior to cetuximab alone in terms of overall survival.

FIERCE-HN opened for enrollment in December 2023 and currently expects to complete enrollment by May 2026. For more information, visit www.FIERCEHN.com.

Poster Title: "A phase 1b dose escalation study of AV-380 (anti-GDF15 monoclonal antibody) in combination with standard-of-care therapy in cancer patients with cachexia."– (Abstract: TPS12142; Poster: 159a)

AVEO presented a second trial in progress poster for their AV-380 phase 1b dose escalation study. During the meeting, the company also announced the official molecule name for AV-380: rilogrotug (pronounced rye-low-grow-tug). Rilogrotug is an immunoglobulin (Ig) G1 monoclonal antibody (mAb) intended to bind circulating human growth differentiation factor 15 (GDF-15), a cytokine involved in cancer-induced cachexia. This open label ascending dose study is designed to evaluate the safety, pharmacokinetics, pharmacodynamics, and immunogenicity of rilogrotug in cancer patients with cachexia.

SACHI is a Phase III study of the savolitinib and osimertinib combination for the treatment of patients with locally advanced or metastatic epidermal growth factor receptor ("EGFR") mutation-positive non-small cell lung cancer ("NSCLC") with MET amplification after disease progression on first-line EGFR inhibitor therapy (clinicaltrials.gov identifier NCT05015608).

Title:

Savolitinib combined with osimertinib versus chemotherapy in EGFR-mutant and MET-amplification advanced NSCLC after disease progression on EGFR tyrosine kinase inhibitor: Results from a randomized Phase III SACHI study

Lead Author:

Shun Lu, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China

Session:

Oral Abstract Session: Lung Cancer – Non-Small Cell Metastatic

Abstract Number:

LBA8505

Date & Time:

Sunday, June 1, 2025, 8:00 AM Central Daylight Time

Location:

Arie Crown Theater

Prof. Shun Lu, Chief of the Shanghai Lung Cancer Center at Shanghai Chest Hospital, School of Medicine, Shanghai Jiaotong University, and Principal Investigator of the SACHI study, said, "The results from the SACHI Phase III study represent a significant advancement in the treatment of EGFR mutation-positive NSCLC with MET amplification. The savolitinib and osimertinib combination demonstrates promising efficacy in patients who have progressed on prior EGFR inhibitor therapy. These findings highlight the potential of this novel, chemotherapy-free combination to enable a continued oral regimen, offering a convenient and well-tolerated treatment option that addresses critical unmet needs for patients with this challenging disease."

HUTCHMED will host a webcast to discuss the data presented at the ASCO (Free ASCO Whitepaper) Annual Meeting at 8:30 -9:00 am HKT on Tuesday, June 3, 2025 (8:30 – 9:00 pm EDT on June 2, 2025). The event will be held in English and can be accessed via www.hutch-med.com/event. A replay will also be available on the website shortly after the event.

As of the interim analysis data cut-off of August 30, 2024, a total of 211 patients were randomized to receive the savolitinib and osimertinib combination or chemotherapy. In the intention to treat (ITT) population, the median progression-free survival ("PFS") assessed by investigator was 8.2 months with savolitinib plus osimertinib, compared to 4.5 months with chemotherapy (hazard ratio ["HR"] 0.34; 95% confidence interval ["CI"] 0.23-0.49; p < 0.0001). The independent review committee ("IRC") assessed median PFS was 7.2 months vs 4.2 months, respectively (HR 0.40; 95% CI 0.28-0.59; p < 0.0001).

The investigator-assessed objective response rate (ORR) was 58% in the savolitinib plus osimertinib group compared to 34% for patients in the chemotherapy group. The disease control rate (DCR) was 89% vs 67% and the median duration of response (DoR) was 8.4 months vs 3.2 months, respectively. Overall survival was not mature at the time of the interim analysis.

Efficacy outcomes in the third-generation EGFR tyrosine kinase inhibitor ("TKI")–treated patients were comparable with those in the intention-to-treat and third-generation EGFR-TKI–naïve populations. In the third generation EGFR-TKI–treated subgroup, the investigator-assessed and IRC-assessed median PFS were highly consistent, both at 6.9 vs 3.0 months (HR 0.32; p < 0.0001).

The safety profile of the savolitinib and osimertinib combination was tolerable and no new safety signals were observed. Treatment-emergent adverse events of Grade 3 or above occurred in 57% of patients in the savolitinib plus osimertinib group compared to 57% for patients in the chemotherapy group, suggesting a favorable safety profile.

In January 2025, the Independent Data Monitoring Committee (IDMC) of SACHI has considered that the study has met the pre-defined primary endpoint of PFS in a planned interim analysis and as a result, enrollment into the study has concluded. Supported by data from SACHI, a New Drug Application (NDA) for the combination of savolitinib and osimertinib for the treatment of patients with locally advanced or metastatic EGFR mutation-positive NSCLC with MET amplification after disease progression on first-line EGFR inhibitor therapy has been accepted and granted priority review by the China National Medical Products Administration (NMPA).

About Savolitinib

Savolitinib is an oral, potent, and highly selective MET TKI that has demonstrated clinical activity in advanced solid tumors. MET is a tyrosine kinase receptor that has an essential role in normal cell development. Savolitinib blocks atypical activation of the MET receptor tyrosine kinase pathway that occurs because of mutations (such as exon 14 skipping alterations or other point mutations), gene amplification or protein overexpression. MET overexpression and/or amplification can lead to tumor growth and the metastatic progression of cancer cells, and is a known mechanism of acquired resistance to EGFR TKIs. The prevalence of MET depends on the sample type, detection method and assay cut-off used.

Savolitinib is approved in China and is marketed under the brand name ORPATHYS by our partner, AstraZeneca, for the treatment of adult patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alteration, representing the first selective MET inhibitor approved in China. It has been included in the National Reimbursement Drug List of China (NRDL) since March 2023.

It is currently under clinical development for multiple tumor types, including lung, kidney, and gastric cancers as a single treatment and in combination with other medicines.
