On April 21, 2026 Merck (NYSE: MRK), known as MSD outside of the United States and Canada, and Eisai reported results from the Phase 3 LITESPARK-012 trial evaluating combination regimens for the first-line treatment of patients with advanced clear cell renal cell carcinoma (RCC). The trial evaluated the triplet therapy of KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, plus LENVIMA (lenvatinib), the orally available multiple receptor tyrosine kinase inhibitor (TKI) discovered by Eisai, plus WELIREG (belzutifan), Merck’s first-in-class, oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor. The study also evaluated MK-1308A, the coformulation of KEYTRUDA and quavonlimab, Merck’s investigational anti-CTLA-4 antibody, plus LENVIMA. Both combination regimens were compared to KEYTRUDA plus LENVIMA for these patients.

At a pre-specified interim analysis, the combination regimens did not meet the dual primary endpoints of progression-free survival (PFS) and overall survival (OS) for the first-line treatment of patients with RCC compared to KEYTRUDA plus LENVIMA. The safety profiles of the combination regimens were consistent with those observed in previously reported studies evaluating the individual medicines and the KEYTRUDA plus LENVIMA combination. A full evaluation of the data from this study is ongoing, and Merck and Eisai will work with investigators to share the results with the scientific community.

"With the LITESPARK-012 trial, we explored whether combining therapies with established activity could improve upon well-established standards set by KEYTRUDA-based regimens, reflecting our commitment to continuously explore ways to improve outcomes for the kidney cancer community," said Dr. M. Catherine Pietanza, Vice President, Global Clinical Development, Merck Research Laboratories. "While these regimens did not demonstrate the results we hoped, the data deepen our understanding of advanced renal cell carcinoma and will help shape the next generation of treatment approaches."

"While we are disappointed that LITESPARK-012 did not meet its primary endpoints, the findings reinforce the central role of KEYTRUDA plus LENVIMA in the first-line treatment of patients with advanced renal cell carcinoma," said Dr. Corina Dutcus, Senior Vice President, Oncology Global Clinical Development Lead at Eisai Inc. "Findings from trials such as this play an important role in shaping health care providers’ perspectives as the treatment paradigm for advanced renal cell carcinoma continues to evolve. We are committed to advancing the care of people living with this disease and we are grateful to the patients, caregivers and investigators whose participation and dedication made this research possible."

Results from the LITESPARK-012 trial do not affect other ongoing trials from the LITESPARK clinical program, including those conducted jointly with Eisai. As previously announced, the U.S. Food and Drug Administration (FDA) has accepted two supplemental New Drug Applications (sNDA) for review based on the Phase 3 LITESPARK-011 trial evaluating WELIREG in combination with LENVIMA for certain previously treated patients with advanced RCC and has set a Prescription Drug User Fee Act (PDUFA), or target action, date of Oct. 4, 2026.

KEYTRUDA is currently approved as adjuvant monotherapy and in combination regimens for appropriate patients with RCC in the U.S., European Union (EU), Japan and other countries around the world. For more information, please see the "Selected KEYTRUDA (pembrolizumab) Indications in the U.S." section below.

KEYTRUDA plus LENVIMA is approved in the U.S., EU, Japan and other countries for the first-line treatment of adult patients with advanced RCC. Lenvatinib is approved as KISPLYX for advanced RCC in the EU.

LENVIMA in combination with everolimus is approved in the U.S., EU and other regions for the treatment of adult patients with advanced RCC following one prior anti-angiogenic therapy.

WELIREG is approved in the U.S., EU, Japan and other countries for the treatment of adult patients with advanced clear cell RCC following a PD-1/PD-L1 inhibitor and 1-2 VEGF-TKIs based on results from the Phase 3 LITESPARK-005 trial.

About LITESPARK-012

LITESPARK-012 is a randomized, open-label Phase 3 trial (ClinicalTrials.gov, NCT04736706) evaluating either the triplet therapy of KEYTRUDA plus LENVIMA plus WELIREG or MK-1308A plus LENVIMA compared to KEYTRUDA plus LENVIMA for the first-line treatment of patients with advanced clear cell RCC. The primary endpoints are PFS, as assessed by blinded independent central review (BICR) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and OS. Secondary endpoints are objective response rate and duration of response as assessed by BICR according to RECIST v1.1, as well as safety. The study enrolled 1,688 patients who were randomized to receive:

KEYTRUDA (400 mg intravenously [IV] every six weeks [Q6W]) plus LENVIMA (20 mg orally once daily [QD]) plus WELIREG (120 mg orally QD);
MK-1308A (coformulation of pembrolizumab [400 mg] and quavonlimab [25 mg] IV Q6W) plus LENVIMA (20 mg orally QD);
KEYTRUDA (400 mg IV Q6W) plus LENVIMA (20 mg orally QD).
All study drugs were continued until protocol-specified discontinuation criteria. KEYTRUDA and MK-1308A were administered for up to two years (approximately 18 cycles). WELIREG and LENVIMA may have been administered in combination or as a single agent until progressive disease or discontinuation.

About renal cell carcinoma

Renal cell carcinoma is the most common type of kidney cancer, with about nine out of 10 kidney cancer diagnoses being RCC. In 2022, there were about 435,000 new cases of kidney cancer diagnosed and approximately 156,000 deaths from the disease worldwide. Renal cell carcinoma is about twice as common in men as in women. Most cases of RCC are discovered incidentally during imaging tests for other abdominal diseases, and about 70% are a form called clear cell RCC, which tends to be more aggressive and faster spreading. Approximately 30% of patients with kidney cancer are diagnosed at an advanced stage.

Turbine’s Virtual Assays simulate biological response across thousands of biological samples and hundreds of drugs, generating predictive insights to identify and prioritize targets, therapies, and combinations. The predictions will be enhanced through the incorporation of multimodal and drug response data from hundreds of tumor organoid models at Crown Bioscience. Together, the companies create a closed-loop approach linking prediction with validation, improving predictive accuracy, reducing experimental burden, whilst delivering greater biological relevance and translational confidence.

Guided by Turbine’s in silico predictions, select hypotheses can be experimentally validated using Crown Bioscience’s tumor organoid assays, streamlining experimental design, reducing costs, and shortening development timelines.

This approach enables researchers to generate insights earlier, focus resources on the most promising strategies, and make faster, more informed decisions with greater confidence in clinical translatability.

"Translational success depends on how well early insights reflect real patient biology," said John Gu, CEO of Crown Bioscience. "By integrating predictive modeling with our organoid models, we are creating a more robust foundation for decision-making, one that improves confidence, reduces risk, and accelerates the path to the clinic."

"Together with Crown Bioscience, we aim to address a key trade-off in drug discovery between scale and translatability," said Szabolcs Nagy, CEO of Turbine. "Using our Virtual Lab, researchers can already explore millions of hypotheses in silico. By integrating with Crown’s organoid platform, we enable virtual experimentation that better reflects patient biology, helping close the translatability gap."

Overall survival subgroup analyses for prior taxane use in the phase 3 ROSELLA trial of relacorilant plus nab-paclitaxel versus nab-paclitaxel monotherapy in patients with platinum-resistant ovarian cancer (GOG-3073, ENGOT-ov72, APGOT-Ov10, LACOG-0223, and ANZGOG-2221/2023)

Oral Abstract Session – Gynecologic Cancer
May 29, 2026, 2:45 PM – 5:45 PM CDT
Abstract Number: 5503
Lifyorli, in combination with nab-paclitaxel, was approved by the U.S. Food and Drug Administration (FDA) in March 2026 for the treatment of adults with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received one to three prior systemic treatment regimens, at least one of which included bevacizumab. Lifyorli is the first FDA-approved selective glucocorticoid receptor antagonist (SGRA). It is included in the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) as a preferred regimen for patients with platinum-resistant ovarian cancer.

The ROSELLA trial was conducted in collaboration with The GOG Foundation, Inc. (GOG-F), the European Network of Gynaecological Oncological Trial groups (ENGOT), the Asia-Pacific Gynecologic Oncology Trials Group (APGOT), the Latin American Cooperative Oncology Group (LACOG) and the Australia New Zealand Gynaecological Oncology Group (ANZGOG).

About Ovarian Cancer

Ovarian cancer is the fifth most common cause of cancer death in women. Patients whose disease returns less than six months after receiving platinum-containing therapy have "platinum-resistant" disease. There are few treatment options for these women. Approximately 20,000 women with platinum-resistant disease are candidates to start a new therapy each year in the United States, with at least an equal number in Europe.

About Cortisol’s Role in Oncology

Cortisol plays a role in tumor growth through several mechanisms. It helps solid tumors resist chemotherapy by inhibiting cellular apoptosis — the tumor-killing effect chemotherapy is meant to stimulate. In some cancers, cortisol promotes tumor growth by activating oncogenic signaling in the cells to which it binds. Cortisol also suppresses the body’s immune response, which weakens its ability to fight all diseases, including cancer.

Corcept is developing relacorilant in ovarian, endometrial, cervical, pancreatic and prostate cancers. Relacorilant is proprietary to Corcept and is protected by composition of matter, method of use and other patents. It has been designated an orphan drug by the European Commission (EC) for the treatment of ovarian cancer. Corcept has submitted a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) for relacorilant to treat patients with platinum-resistant ovarian cancer.

About Lifyorli

Lifyorli (relacorilant), approved in combination with nab-paclitaxel, is the first U.S. Food and Drug Administration (FDA)-approved selective glucocorticoid receptor antagonist for adults with platinum-resistant ovarian cancer. Lifyorli is an oral medication taken the day before, the day of and the day after treatment with nab-paclitaxel. There is no biomarker requirement to receive Lifyorli. Lifyorli competitively binds to the glucocorticoid receptor (GR), where it enhances chemotherapy sensitivity by inhibiting cortisol’s suppression of apoptosis – the programmed cell death that chemotherapies such as nab-paclitaxel are meant to cause. Lifyorli does not have any effect at the body’s other steroid receptors.

It is included in the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) as a preferred regimen for patients with platinum-resistant ovarian cancer.

Corcept is committed to timely patient access for Lifyorli. For questions regarding product availability, please contact Lifyorli Support at 1-85-LIFYORLI (1-855-439-6754).

LIFYORLI Indication & Usage

LIFYORLI is indicated in combination with nab-paclitaxel for the treatment of adults with platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who have received 1-3 prior systemic treatment regimens, at least one of which included bevacizumab.

IMPORTANT SAFETY INFORMATION

Contraindications:

LIFYORLI is contraindicated in patients receiving systemic glucocorticoids for lifesaving purposes (e.g., immunosuppression after organ transplantation) because LIFYORLI antagonizes the effect of glucocorticoids.

Warnings and Precautions:

Neutropenia and Severe Infections

LIFYORLI in combination with nab-paclitaxel can cause neutropenia, including febrile neutropenia and severe infections. There was one fatal event of septic shock with febrile neutropenia. Thirty-eight percent of patients initiated granulocyte colony-stimulating factor (G-CSF) during the first or second cycle of therapy.

Monitor complete blood counts prior to each weekly treatment with LIFYORLI in combination with nab-paclitaxel and as clinically indicated. Based on the severity of neutropenia, delay dose, reduce dose or permanently discontinue LIFYORLI in combination with nab-paclitaxel. Consider short-acting G-CSF administration as applicable. Consider the possibility of concurrent adrenal insufficiency, particularly in the setting of serious infection.

Adrenal Insufficiency

LIFYORLI is a reversible glucocorticoid receptor antagonist and can cause adrenal insufficiency. Adrenal insufficiency can occur at any time during treatment with LIFYORLI. The risk of adrenal insufficiency is increased in situations of stress, such as acute illness, infection, or surgery. Consider whether supplemental glucocorticoids are required in the perioperative period in patients who have received LIFYORLI within 30 days of surgery. Monitor patients receiving LIFYORLI for signs and symptoms of adrenal insufficiency. Withhold LIFYORLI and administer glucocorticoid therapy if adrenal insufficiency is suspected. High doses of supplemental glucocorticoids may be needed to overcome the glucocorticoid receptor antagonism produced by LIFYORLI. After resolution of adrenal insufficiency, resume previous dose, reduce dose or permanently discontinue LIFYORLI based on severity.

Exacerbation of Conditions Treated with Glucocorticoids

Use of LIFYORLI in patients taking systemic glucocorticoids for other conditions (e.g., autoimmune disorders) may exacerbate these conditions. LIFYORLI is a glucocorticoid receptor antagonist that may make systemic glucocorticoids less effective. Similarly, coadministration of systemic glucocorticoids may make LIFYORLI less effective. Monitor patients for reduced effectiveness of LIFYORLI and glucocorticoids in patients receiving both.

Embryo-Fetal Toxicity

LIFYORLI can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Verify pregnancy status of females of reproductive potential prior to initiating LIFYORLI treatment. Advise females of reproductive potential, including male patients with female partners of reproductive potential, to use effective contraception during treatment with LIFYORLI and for 1 week after the last dose.

Adverse Reactions:

Serious adverse reactions occurred in 35% of patients who received LIFYORLI in combination with nab-paclitaxel. Serious adverse reactions (≥2%) in patients were neutropenia (4%), pneumonia (3.2%), pleural effusion (3.2%), febrile neutropenia (2.1%), and fatigue (2.1%). Fatal adverse reactions (2.1%) in patients were septic shock (0.5%), cardiac arrest (0.5%), ischemic stroke (0.5%), and intestinal perforation (0.5%).

Permanent discontinuation of LIFYORLI in combination with nab-paclitaxel due to adverse reactions occurred in 9% of patients. The adverse reaction (>2%) that resulted in permanent discontinuation of LIFYORLI in patients was intestinal obstruction (2.6%). Dosage interruptions of LIFYORLI due to an adverse reaction occurred in 72% of patients. Adverse reactions (≥5%) that required dosage interruptions of LIFYORLI in combination with nab-paclitaxel in patients included neutropenia (44%), anemia (12%), and fatigue (7%). Adverse reactions requiring dose reductions of LIFYORLI included fatigue (1.6%), decreased appetite (1.2%), abdominal pain (0.5%), neutropenia (0.5%), edema (0.5%), and sciatica (0.5%). LIFYORLI should be interrupted or discontinued when nab-paclitaxel is interrupted or discontinued.

The most common adverse reactions (>20%) of patients treated with LIFYORLI plus nab-paclitaxel, including laboratory abnormalities, were decreased hemoglobin, decreased neutrophils, fatigue, nausea, diarrhea, decreased platelets, rash, and decreased appetite.

Drug Interactions:

Strong CYP3A Inducers: Avoid coadministration of LIFYORLI plus nab-paclitaxel with strong CYP3A inducers. Both relacorilant and paclitaxel are CYP3A substrates. Coadministration of strong CYP3A inducers can decrease concentrations of relacorilant and paclitaxel, which may reduce their effectiveness.
CYP2C8 and Moderate CYP3A Inducers: Monitor for reduced effectiveness of LIFYORLI plus nab-paclitaxel with CYP2C8 inducers and moderate CYP3A inducers. Paclitaxel is a substrate of CYP2C8 and CYP3A, and relacorilant is a CYP3A substrate. Coadministration of CYP2C8 and moderate CYP3A inducers can decrease concentrations of paclitaxel and relacorilant, which may reduce their effectiveness.
CYP2C8 Inhibitors: Monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended. Paclitaxel is a substrate of CYP2C8. Coadministration of CYP2C8 inhibitors may increase concentrations of paclitaxel, which may increase the risk of adverse reactions.
CYP3A Substrates: Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP3A substrates. Relacorilant is a strong CYP3A inhibitor. Relacorilant increases exposure of CYP3A substrates which may increase the risk for adverse reactions related to these substrates.
Certain CYP2C8 Substrates: Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP2C8 substrates where minimal concentration changes may lead to reduced effectiveness. Relacorilant is a weak CYP2C8 inducer. Relacorilant decreases exposure of CYP2C8 substrates which may decrease the effectiveness related to these substrates.
Use in Specific Populations:

Lactation: Advise women not to breastfeed during treatment with LIFYORLI and for 1 week after the last dose.
Geriatric Use: A higher incidence of grade 3-4 adverse events and dosage modification occurred in patients aged ≥65 years compared to younger adult patients.
Hepatic Impairment: Avoid LIFYORLI in combination with nab-paclitaxel in patients with moderate or severe hepatic impairment (total bilirubin >1.5 to 10x ULN and any AST).

This is an important emerging challenge in mCRPC, and one that will help define the next phase of progress in the field."

Abstract Title: CONVERGE-01 part 3: Ac-225 rosopatamab tetraxetan (CONV01-a) in Lu-PSMA pretreated metastatic castration-resistant prostate cancer (mCRPC).
Abstract Number: 5011
Format: Oral Presentation
Session Type/Title: Clinical Science Symposium – Radiation Re-Imagined: Radioligand Innovation in Prostate Cancer
Date and Time: June 1, 3:00 PM-4:30 PM CDT
Presenter: Michael J. Morris, MD, Prostate Cancer Section Head, Memorial Sloan Kettering Cancer Center

About the CONVERGE-01 Trial
The CONVERGE-01 trial is a Phase II, randomized, open-label, multicenter three-part study designed to assess the safety and efficacy of CONV01-α in patients with mCRPC. In Part 1, patients received rosopatamab tetraxetan to characterize the biodistribution of the radioantibody to target organs and prostate cancer lesions. Participants were then enrolled in either Part 2 (dose optimization) or Part 3 (dose escalation) depending on their prior treatment history. Part 2 enrolled Lu-177-PSMA-radioligand therapy-naïve participants and Part 3 enrolled participants who received prior Lu-177-PSMA-radioligand therapy. All patients will receive Ac-225 rosopatamab tetraxetan in a single fractionated two-week cycle. Further details of the trial can be found at www.clinicaltrials.gov under NCT identifier: NCT06549465.

About CONV01-α
CONV01-α is a PSMA-targeted Ac-225 radioantibody that pairs antibody precision with the localized potency of alpha radiation. CONV01-α, which is being developed to improve the treatment of metastatic castration-resistant prostate cancer (mCRPC), uses a humanized monoclonal antibody directed at prostate-specific membrane antigen (PSMA), a well-established and highly expressed antigen in prostate cancer. CONV01-α is differentiated by its ability to precisely deliver actinium-225 (Ac-225) through this PSMA-targeting antibody, enabling short-range, high-energy alpha particle radiation that creates focused DNA damage within tumor cells while limiting exposure to surrounding tissues. Initial studies in more than 120 patients have established clinical proof-of-concept for CONV01-α, showing consistent antitumor activity and a differentiated safety profile. This selectivity, combined with strong tumor retention and minimal salivary and renal uptake, supports the potential of CONV01-α to be a clinically impactful therapy for PSMA-positive cancers.
