"These findings support that NGEN-143 can deliver an unprecedented breadth of targets and activate cytotoxic T cells, as compared to other currently available cancer vaccines, making NGEN-143 a better potential option for patients" said Todd Binder, Chief Executive Officer of NEUVOGEN. "Our dedicated team is eager to bring this new cancer vaccine forward to treat patients with non-small cell lung cancer (NSCLC)."

Key Findings:

In a fully human in vitro system, NGEN-143 expands effector T cells against a broad repertoire of both tumor-associated antigens and common shared neo-antigens across a wide range of HLA types.

NGEN-143 activates polyfunctional, cytotoxic T cells; the response is dominated by CD8+ cells without any evidence of antigenic competition. CD4+ T cell responses are skewed toward CD4+ Th1 cells over CD4+ Th2 cells.

NGEN-143 activated T cells efficiently kill human tumor cells in a caspase-3 dependent manner.

In the ‘immune warm’ CT26 mouse tumor model, vaccine abrogates or slows tumor growth – durable protection against rechallenge supports efficient induction of immune memory; vaccine + αPD1 improved survival over αPD1 monotherapy.

In the ‘immune cold’ B16F10 mouse tumor model, our vaccine approach inhibits tumor growth and prolongs survival; vaccine + αPD1 improved survival.
Bernadette Ferraro, Ph.D., NEUVOGEN’s Vice President, Immuno-oncology, is scheduled to present "An optimized off-the-shelf whole tumor cell vaccine activates T cells that recognize a diverse antigen repertoire with potential to provide meaningful clinical benefit to patients with NSCLC," at AACR (Free AACR Whitepaper) on Tuesday, April 29 from 2:00 – 5:00 PM CT. A copy of the poster will be made available for download at neuvogen.com/our-science after the meeting concludes.

"The double-digit revenue growth in the first quarter driven by the continued growth of Jakafi and Opzelura and the recent launch of Niktimvo, puts us on track to achieve our full year objectives," said Hervé Hoppenot, Chief Executive Officer, Incyte. "We also continued to advance our innovative pipeline, which will be critical for driving long-term growth. The positive Phase 3 results for povorcitinib in hidradenitis suppurativa in addition to the proof-of-concept in chronic spontaneous urticaria, strengthens the potential of povorcitinib as a multibillion-dollar product addressing patient needs across the five indications currently in development."
Key Commercial Highlights
Jakafi(ruxolitinib):
Net product revenues for the first quarter 2025 of $709 million (+24% Y/Y):
▪Net product revenue growth in the first quarter of 2025 versus the same quarter in the prior year, was driven by an increase in paid demand, the positive impact of the Part D redesign under the Inflation Reduction Act, partially offset by growth in 340B, and less de-stocking compared to the first quarter of 2024. Jakafi inventory levels were within normal range at the end of the first quarter of 2025.

Opzelura(ruxolitinib) cream:
Net product revenues for the first quarter 2025 of $119 million (+38% Y/Y):
▪U.S. net product revenue of $95 million in the first quarter of 2025 increased 20% compared to the first quarter of 2024 driven by patient demand and refills in both atopic dermatitis (AD) and vitiligo, partially offset by a reduction in channel inventory. Opzelura inventory levels were within normal range at the end of the first quarter of 2025.
▪Ex-U.S. net product revenues of $23 million in the first quarter of 2025 were primarily driven by continued growth in sales in Germany and France, as well as the recent launches in Italy and Spain.

Inflammation and Autoimmunity (IAI) – key highlights
Ruxolitinib Cream
▪In March 2025, results from two Phase 3 studies (TRuE-PN1 and TRuE-PN2) evaluating ruxolitinib cream in patients with prurigo nodularis (PN) were presented in a late-breaking oral session at the American Academy of Dermatology annual meeting. The TRuE-PN1 study met the primary endpoint of a > 4-point improvement from baseline in Worst-Itch Numeric Rating Scale (WI-NRS4) at Week 12 and all key secondary endpoints. The TRuE-PN2 study did not reach statistical significance for the primary endpoint, resulting in the key secondary endpoints with nominal p-values. These key secondary endpoints still demonstrate positive trends for ruxolitinib cream 1.5% versus vehicle. These data will inform planned discussions with regulatory authorities on submission.
▪A Phase 3 trial for ruxolitinib cream in mild to moderate hidradenitis suppurativa (HS) is on track to initiate in the first half of 2025 following achieving alignment on the study design with FDA.
Povorcitinib (INCB54707)
▪In April 2025, Incyte announced positive topline results from the Phase 2 study evaluating povorcitinib in patients with chronic spontaneous urticaria (CSU). The study met the primary endpoint at Week 12 of change from baseline in the Urticaria Activity Score summed over 7 days (UAS7). Povorcitinib was well tolerated with no new safety signals observed. These data will support planned discussions with regulatory agencies and will be presented at an upcoming medical conference.
▪In March 2025, positive results from the Phase 3 studies (STOP-HS1 and STOP-HS2) of povorcitinib in patients with HS were presented and demonstrated that both studies met their primary endpoint of Hidradenitis Suppurativa Clinical Response (HiSCR) at Week 12 and at both tested doses (45mg and 75mg). In addition, at Week 12, patients treated with povorcitinib achieved deep levels of clinical response with a greater proportion achieving HiSCR75, reduction in flares, >3-point decrease in the Skin Pain Numeric Rating Scale (NRS) score and Skin Pain NRS30. Furthermore, povorcitinib demonstrated rapid onset of response, including rapid skin pain reduction. Additional longer-term data demonstrate that at Week 18, HiSCR rates continue to improve over Week 12 in patients treated with povorcitinib including high levels of response in those patients previously treated on placebo and crossed over to active povorcitinib treatment. These data support the planned regulatory submission of povorcitinib for the treatment of HS worldwide.
▪Two Phase 3 studies (STOP-PN1 and STOP-PN2) evaluating povorcitinib in patients with PN versus placebo are ongoing and enrolling patients.
▪A Phase 2 trial evaluating povorcitinib in asthma is ongoing and enrolling. Data are anticipated in the second half of 2025.

2025 First Quarter Financial Results
The financial measures presented in this press release for the three months ended March 31, 2025 and 2024 have been prepared by the Company in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), unless otherwise identified as a Non-GAAP financial measure. Management believes that Non-GAAP information is useful for investors, when considered in conjunction with Incyte’s GAAP disclosures. Management uses such information internally and externally for establishing budgets, operating goals and financial planning purposes. These metrics are also used to manage the Company’s business and monitor performance. The Company adjusts, where appropriate, for expenses in order to reflect the Company’s core operations. The Company believes these adjustments are useful to investors by providing an enhanced understanding of the financial performance of the Company’s core operations. The metrics have been adopted to align the Company with disclosures provided by industry peers.
Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used in conjunction with and to supplement Incyte’s operating results as reported under GAAP. Non-GAAP measures may be defined and calculated differently by other companies in our industry.
As changes in exchange rates are an important factor in understanding period-to-period comparisons, Management believes the presentation of certain revenue results on a constant currency basis in addition to reported results helps improve investors’ ability to understand its operating results and evaluate its performance in comparison to prior periods. Constant currency information compares results between periods as if exchange rates had remained constant period over period. The Company calculates constant currency by calculating current year results using prior year foreign currency exchange rates and generally refers to such amounts calculated on a constant currency basis as excluding the impact of foreign exchange or being on a constant currency basis. These results should be considered in addition to, not as a substitute for, results reported in accordance with GAAP. Results on a constant currency basis, as the Company presents them, may not be comparable to similarly titled measures used by other companies and are not measures of performance presented in accordance with GAAP.

The presentation highlights strong evidence of meaningful clinical activity, robust immune activation in vivo, and a well-characterized safety profile, further supporting the momentum behind the ongoing Phase 2 study as well as the value proposition for developing invikafusp as monotherapy in PD1 resistant TMB-H cancers.

"Today’s data represent a major step forward for Marengo and for the field of IO to advance a new class of cancer immunotherapy: Immune Activation Inducers (IAI)," said Zhen Su, M.D., M.B.A., Chief Executive Officer of Marengo Therapeutics. "Invikafusp alfa’s ability to selectively activate and expand a key T cell subset to drive meaningful anti-tumor responses across a range of PD-1 resistant tumors gives us confidence in our precision T cell activation approach. The emerging clinical signals in both colorectal and lung cancers further underscore invikafusp’s pan-tumor potential and justify our focused expansion into these high-need indications."

"Colorectal cancer is less sensitive to immunotherapy except in a very small percentage of MSI-H tumors. The field has seen few, if any, immunotherapy agents achieve single-agent activity in PD-1 resistant colorectal cancer," said Josep Tabernero, M.D., Director of Vall d’Hebron Institute of Oncology (VHIO). "The clinical signals observed with invikafusp alfa in both CRC and other tumor types are highly encouraging and warrant further clinical investigation to fully realize the clinical potential of this novel T cell agonist approach."

Invikafusp alfa is Marengo’s first-in-class dual T cell agonist, designed with a bi-specific antibody format to selectively engage and activate the Vβ6 and Vβ10 subsets of T cells in vivo, promoting durable anti-tumor immunity.

Updated Findings from the STARt-001 Clinical Plenary Presentation:

Clinically meaningful anti-tumor activity as monotherapy in anti-PD(L)1-resistant tumors at the recommended Phase 2 dose (RP2D) of 0.08 mg/kg:
61% disease control rate in heavily pretreated, PD-1 resistant tumors dosed at 0.08 or 0.12 mg/kg
52% tumor regression rate observed across multiple tumor types, including colorectal cancer (CRC), non-small cell lung cancer (NSCLC), cervical, squamous cell carcinoma of the head and neck (SCCHN), and melanoma
Objective responses in colorectal cancer and NSCLC:
3 responders out of 10 TMB-high metastatic CRC patients (across RAS wild-type, RAS mutant, and MSI-H subtypes)
1 additional responder with 73% tumor regression out of 2 anti-PD(L)1-resistant TMB-high NSCLC patients
Mechanism of Action and Translational Insights:
Invikafusp promoted potent, selective expansion of peripheral CD8+ Vβ6/Vβ10 T cells, which acquired a novel "memory-like effector" phenotype in both blood and tumor tissue
Expanded and activated Vβ T cells in post treatment tumor tissues consistent with enhanced anti-tumor function
Safety Profile:
Consistent with a selective T cell activation mechanism
Adverse events were generally transient and manageable with supportive care
Based on these early clinical and preclinical findings, the U.S. Food and Drug Administration has granted Fast Track Designation to invikafusp alfa for the treatment of patients with TMB-high colorectal cancer.

The Phase 2 portion of the STARt-002 trial is actively enrolling patients across multiple tumor types, including TMB-H metastatic colorectal cancer, MSI-H and TMB-H tissue-agnostic solid tumors.

About DISC-0974

DISC-0974 is an investigational monoclonal antibody (mAb) targeting a BMP-signaling co-receptor called hemojuvelin (HJV) and is designed to suppress hepcidin production and increase serum iron levels in patients suffering from anemia of inflammation. DISC-0974 was in-licensed by Disc from AbbVie in 2019. Anemia of inflammation arises from abnormally elevated hepcidin and is the second most common form of anemia, affecting millions of patients in the US across numerous diseases, such as chronic kidney disease, myelofibrosis, cancer, autoimmune diseases, and other conditions with an inflammatory component. Disc has established clinical proof-of-mechanism of DISC-0974 in a Phase 1 trial of healthy volunteers, completed a Phase 1b clinical trial in patients with myelofibrosis and anemia, and initiated a Phase 2 clinical trial of DISC-0974 in patients with MF anemia, as well as a Phase 1b/2a clinical trial of DISC-0974 in patients with chronic kidney disease and anemia who are not receiving dialysis.

DISC-0974 is an investigational agent and is not approved for use as a therapy in any jurisdiction worldwide.

About Anemia of Myelofibrosis

Myelofibrosis (MF) is a rare, chronic blood cancer that currently affects an estimated 25,000 patients in the United States alone. Severe, progressive, and treatment resistant anemia is a primary clinical manifestation of MF. At diagnosis, over 80% of MF patients have anemia, which progressively worsens and ultimately renders the majority of patients dependent on chronic red blood cell transfusions. Recent studies have shown hepcidin to be a key molecular driver of anemia in myelofibrosis. Hepcidin is elevated by approximately 12-fold in MF patients, and is correlated with disease severity, anemia, and the need for red blood cell transfusions.

The composition of a patient’s intestinal microbiome is known to impact the response to immunotherapies, most noticeably CPI, but the mechanisms are poorly understood. MB097 comprises nine different species of gut commensal bacteria, all linked to positive CPI response in multiple clinical studies. Microbiotica has developed in vitro human systems using primary immune cells to investigate how gut bacteria modulate the immune response to cancer. These assays have demonstrated that three of the MB097 strains induce dendritic cells to produce high levels of IL-12, which in turn stimulates Cytotoxic T Lymphocytes and NK cells with potent tumour cell killing activity. Dr Mat Robinson, Microbiotica’s Senior Vice-President Research, presented these novel findings in a poster entitled ‘Clinical response to immune checkpoint inhibitors in melanoma is associated with distinct gut bacterial species that promote anti-tumour immunity by different mechanisms’. The poster can be accessed here.

Dr Mat Robinson, Microbiotica’s SVP Research, said, "These exciting results start to unravel the complex biology of how gut commensal bacteria drive immune checkpoint inhibitor responses. The induction of dendritic cells to produce IL-12 complement the recently reported data showing that other MB097 strains release metabolites that enhance immune-mediated cancer cell killing. Together, these findings demonstrate that the different strains within MB097 can interact with the immune system of cancer patients in multiple ways to enhance immunotherapy efficacy."

MB097 is being tested in an international Phase 1b clinical study, in combination with KEYTRUDA (pembrolizumab), MSD’s anti-PD-1 therapy, in patients with cutaneous melanoma who have failed to respond to immunotherapies. Data readout is expected by the end of 2025.
