"The successful FDA Type D meeting provides darovasertib a registrational path as neoadjuvant therapy for UM, using primary clinical endpoints of eye preservation and proportion of patients with vision loss, with no detriment to EFS as a secondary endpoint required for both cohorts. Based on the promising clinical efficacy and safety observed with darovasertib in the neoadjuvant setting in over 90 patients and the recent Breakthrough Therapy Designation by the US FDA, we are excited to advance the darovasertib program into our second registrational trial," said Dr. Darrin Beaupre, M.D., Ph.D., Chief Medical Officer, IDEAYA Biosciences.

Darovasertib is a potent and selective protein kinase C (PKC) inhibitor being developed to broadly address primary and metastatic UM (MUM). Darovasertib has received U.S. FDA Breakthrough Therapy Designation as neoadjuvant therapy in enucleation recommended primary UM and Fast Track designation for darovasertib in combination with crizotinib in adult patients with metastatic uveal melanoma (MUM), where a Phase 2/3 registration-enabling trial of the darovasertib and crizotinib combination in 1L HLA-A2-negative MUM is ongoing. Darovasertib has also been designated as an Orphan Drug by the U.S. FDA in UM, including in MUM.

FDA Guidance from the Type D Meeting on the Phase 3 Neoadjuvant Darovasertib Registrational Trial Design for Potential Regulatory Approval in Primary UM

IDEAYA is targeting to initiate the Phase 3 randomized clinical trial evaluating neoadjuvant darovasertib in primary UM in the first half of 2025. The randomized Phase 3 clinical trial design incorporates guidance and feedback from the U.S. FDA following a recent Type D meeting.

In the Phase 3 clinical trial, we currently project approximately 520 patients will be randomized 2:1 to the darovasertib treatment versus control arm. There will be 2 cohorts enrolled: 1) 120 enucleation eligible UM patients, 2) 400 PB eligible UM patients. For the enucleation cohort, the randomization will be with or without darovasertib as neoadjuvant therapy. For the PB cohort, the randomization will be darovasertib followed by PB versus PB alone.

Key highlights of the Phase 3 registrational trial design in neoadjuvant UM, based on FDA guidance:

Eye preservation rate (exceed lower bound of 10% eye preservation rate with a 95% confidence interval) is the primary endpoint for the enucleation UM cohort
Proportion of patients with vision loss from the time of randomization and time of completion of PB is the primary endpoint for the plaque brachytherapy cohort. Vision detriment will be measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) Best-Corrected Visual Acuity (BCVA) of >15-letters lost
No detriment to Event-Free-Survival (EFS) is a secondary endpoint for both cohorts and is required for approval. No detriment is defined as overlapping confidence intervals
Additional secondary endpoints: Overall Response Rate (>20% ocular tumor shrinkage by product of diameters), proportion of patients with clinically significant macular edema, proportion of subjects with 20/200 vision loss or worse (legal blindness), proportion of subjects with reduction of radiation dose of >20% delivered to key eye structures
Potential to submit the enucleation cohort data for regulatory review earlier than the PB cohort pending the EFS data maturity in both cohorts
300mg BID darovasertib will be the move-forward dose for the registrational trial

On April 14, 2025 Bio-Thera Solutions Inc.

Increase survival in patients acutely exposed to myelosuppressive doses of radiation (Hematopoietic Subsyndrome of Acute Radiation Syndrome).
Limitations of Use
UDENYCA is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATION: Patients with a history of serious allergic reactions to pegfilgrastim products or filgrastim products. Reactions have included anaphylaxis.

WARNINGS AND PRECAUTIONS:

Fatal splenic rupture: Evaluate patients who report left upper abdominal or shoulder pain for an enlarged spleen or splenic rupture.
Acute respiratory distress syndrome (ARDS): Evaluate patients who develop fever, lung infiltrates, or respiratory distress. Discontinue UDENYCA in patients with ARDS.
Serious allergic reactions, including anaphylaxis: The majority of reported events occurred upon initial exposure. Allergic reactions, including anaphylaxis, can recur within days after the discontinuation of initial anti-allergic treatment. Permanently discontinue UDENYCA in patients with serious allergic reactions.
Allergies to Acrylics (UDENYCA ONBODY only): The on-body injector (OBI) for UDENYCA uses acrylic adhesive. For patients who have reactions to acrylic adhesives, use of this product may result in a significant reaction.
Sickle cell crises: Severe and sometimes fatal crises have occurred. Discontinue UDENYCA if sickle cell crisis occurs.
Glomerulonephritis: The diagnoses were based upon azotemia, hematuria (microscopic and macroscopic), proteinuria, and renal biopsy. Generally, events resolved after dose reduction or discontinuation. Evaluate and consider dose-reduction or interruption of UDENYCA if causality is likely.
Leukocytosis: White blood cell (WBC) counts of 100 x 109/L or greater have been observed in patients receiving pegfilgrastim products. Monitoring of complete blood count (CBC) during UDENYCA therapy is recommended.
Thrombocytopenia: Thrombocytopenia has been reported in patients receiving pegfilgrastim. Monitor platelet counts.
Capillary Leak Syndrome: Has been reported after G-CSF administration, including pegfilgrastim products, and is characterized by hypotension, hypoalbuminemia, edema, and hemoconcentration. Episodes vary in frequency, severity and may be life-threatening if treatment is delayed. If symptoms develop, closely monitor and give standard symptomatic treatment, which may include a need for intensive care.
Potential for Tumor Growth Stimulatory Effects on Malignant Cells: The granulocyte colony stimulating factor (G-CSF) receptor through which pegfilgrastim products and filgrastim products act has been found on tumor cell lines. The possibility that pegfilgrastim products act as a growth factor for any tumor type, including myeloid malignancies and myelodysplasia, diseases for which pegfilgrastim products are not approved, cannot be excluded.
Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) in Patients with Breast and Lung Cancer: MDS and AML have been associated with the use of pegfilgrastim in conjunction with chemotherapy and/or radiotherapy in patients with breast and lung cancer. Monitor patients for signs and symptoms of MDS/AML in these settings.
Potential Device failures (UDENYCA ONBODY only): Missed or partial doses have been reported for products administered via on-body injectors due to the device not performing as intended. In the event of a missed or partial dose, patients may be at increased risk of events such as neutropenia, febrile neutropenia and/or infection than if the dose had been correctly delivered. Instruct patients using the OBI to notify their healthcare professional immediately to determine the need for a replacement dose of UDENYCA if they suspect that the device may not have performed as intended.
Aortitis: Has been reported in patients receiving pegfilgrastim products, occurring as early as the first week after start of therapy. Manifestations may include generalized signs and symptoms such as fever, abdominal pain, malaise, back pain, and increased inflammatory markers (e.g., c-reactive protein and white blood cell count). Consider aortitis when signs and symptoms develop without known etiology. Discontinue UDENYCA if aortitis is suspected.
Nuclear Imaging: Increased hematopoietic activity of the bone marrow in response to growth factor therapy has been associated with transient positive bone imaging changes. Consider when interpreting bone imaging results.
ADVERSE REACTIONS: Most common adverse reactions (≥ 5% difference in incidence compared to placebo) are bone pain and pain in extremity.

To report SUSPECTED ADVERSE REACTIONS, contact 1-800-4-UDENYCA (1-800-483-3692) or notify the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

This unique partnership aims to harness the combined expertise of SMPA and the NCI to further expand the scientific evaluation of enzomenib as a potential therapeutic and explore additional cancers to address unmet patient needs.

Enzomenib is an investigational, oral, small-molecule currently being clinically evaluated by SMPA in Phase 1/2 clinical trials for relapsed or refractory acute leukemia. Enzomenib is designed to target the menin and mixed-lineage leukemia protein interaction, a key interaction for acute leukemia and other cancer cell growth. In preclinical studies, enzomenib demonstrated selective growth inhibition in human acute leukemia cell lines with KMT2A (MLL) rearrangements or NPM1 mutations – cancers with particularly high mortality rates and limited treatment options.1,3

As part of the collaboration, enzomenib will be explored in MyeloMATCH (Myeloid Malignancies Molecular Analysis for Therapy Choice), an NCI precision medicine clinical trial designed to improve treatment outcomes for individuals diagnosed with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS). Enzomenib will also be explored with other important NCI programs.

"We are highly encouraged by the preliminary data showing promising clinical activity of enzomenib in patients with relapsed/refractory acute leukemia, and with the support and partnership of the National Cancer Institute, we are poised to continue this positive momentum by expanding exploration of its application across additional cancers," said Jatin Shah, M.D., Chief Medical Officer, Oncology, SMPA. "We’re honored to partner with the National Cancer Institute whose scientific expertise, resources and commitment to advancing oncological research will enable an even broader pursuit of scientific innovation on behalf of patients with urgent and unmet needs."

About Enzomenib
Enzomenib is an investigational, oral, small molecule inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction, a key interaction in acute leukemia and other tumor cell proliferation and growth. Menin is a scaffold nuclear protein which plays key roles in gene expression and protein interactions involved in many biological pathways, including cell growth, cell cycle, genomic stability, and hematopoiesis.1,2 In preclinical studies, enzomenib has shown selective growth inhibition in human acute leukemia cell lines with KMT2A (MLL) rearrangements or NPM1 mutations.1,3 Enzomenib reduced the expression of the leukemia-associated genes HOXA9 and MEIS1, and increased the expression of the differentiation gene CD11b in human acute leukemia cell lines with MLL rearrangements and NPM1 mutation.4,5 The safety and efficacy of enzomenib is currently being clinically evaluated in a Phase 1/2 dose escalation/dose expansion study in patients with relapsed or refractory acute leukemia (NCT04988555). The FDA granted Orphan Drug Designation for enzomenib for the indication of acute myeloid leukemia in June 2022. The FDA granted Fast Track Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with MLLr or NPM1m in June 2024. Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) granted Orphan Drug Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with MLLr or NPM1m in September 2024.
