"The FDA approval of PYLARIFY TruVu demonstrates Lantheus’ continued commitment to advancing innovation that directly expands patient access to high-quality diagnostic tools," said Mary Anne Heino, Executive Chairperson and CEO, Lantheus. "The availability of PYLARIFY TruVu addresses a key need identified by clinicians – greater access to our market-leading formulation."

PYLARIFY TruVu was submitted for FDA approval via the 505(b)(2) regulatory pathway, allowing for review based upon previously submitted data from two PYLARIFY pivotal studies: OSPREY and CONDOR. The new formulation has the same diagnostic properties and is expected to offer similar safety and effectiveness as PYLARIFY.

Additionally, PYLARIFY TruVu is designed to enhance product stability at higher radioactive concentrations, supporting more efficient manufacturing and distribution. These improvements are expected to increase batch sizes, enabling manufacturing sites with high‑energy cyclotrons to reach more patients and serve broader geographic markets. Overall, PYLARIFY TruVu has the potential to enhance supply flexibility and improve operating leverage for the network of PMFs that will manufacture and distribute the product.

"As we continue to innovate and expand our portfolio, ensuring a reliable and uninterrupted supply for our customers remains our top priority," said Dorothy Barr, Senior Vice President, Manufacturing and Technical Operations. "The PYLARIFY TruVu formulation is designed to enhance manufacturing efficiency, strengthen supply chain dependability and ultimately improve the healthcare system’s ability to deliver timely, accurate imaging for people with prostate cancer."

PYLARIFY TruVu is expected to be commercially available in the fourth quarter of 2026 and will be introduced on a rolling geographic basis, allowing customers to transition from PYLARIFY to the new formulation with minimal disruption.

"As a community dedicated to improving the lives of people facing prostate cancer, we’ve seen firsthand how advanced PSMA PET diagnostic tools like PYLARIFY have truly been game changers, providing real-time, highly accurate information that can meaningfully shape treatment decisions," said Gina B. Carithers, President and CEO, Prostate Cancer Foundation. "With prostate cancer incidence expected to rise in the years ahead, it’s encouraging to see companies like Lantheus putting patients first and introducing innovations that help ensure timely, precise imaging while keeping pace with growing demand. Access to accurate diagnostics, especially when metastatic or recurrent disease is suspected, can profoundly impact both quality of life and long-term outcomes for people living with prostate cancer."

More than 760,000 people with prostate cancer have received PSMA PET scans with PYLARIFY since the FDA granted approval in May 2021 based on findings from the OSPREY and CONDOR studies.

PYLARIFY Pivotal Data Summary
The safety and efficacy of PYLARIFY and PYLARIFY TruVu were established based on the PYLARIFY pivotal trials, OSPREY and CONDOR. OSPREY was a phase 2/3 clinical trial of 385 patients. In Cohort A, 252 men with high-risk prostate cancer had evaluable histopathology for determining the diagnostic performance of PYLARIFY in identifying pelvic nodal metastases. OSPREY Cohort A assessed sensitivity, specificity, PPV, and NPV in pelvic lymph nodes and the prostate gland for PSMA-targeted PET with PYLARIFY. The median sensitivity, specificity, PPV and NPV were 38% (26, 51), 96% (94, 99), 77% (62, 92) and 83% (78, 88). Results showed that a PSMA-targeted PET scan with PYLARIFY significantly improved specificity over standard imaging while maintaining comparable sensitivity and delivering high PPV and NPV in men at risk for metastatic prostate cancer prior to initial therapy. Compared to standard imaging, PYLARIFY PET/CT delivered: Significantly higher specificity (97.9% vs 65.1%), nearly three times the PPV (86.7% vs 28.3%) and similar sensitivity to standard imaging (40.3% vs 42.6%).1

CONDOR was a robust, multicenter, phase 3 trial of 208 patients with suspected recurrent or metastatic prostate cancer with negative or equivocal results using standard imaging. The study design assessed correct localization rate (CLR), a metric of diagnostic performance measuring PPV at the patient level enhanced with anatomic lesion matching in patients with biochemically recurrent (BCR) prostate cancer.
CONDOR found that a PSMA-targeted PET scan with PYLARIFY in men with biochemical recurrent prostate cancer achieved the primary endpoint of correct localization rate (CLR): 85%-87% across all 3 readers (lower bound of 95% CI: 78%-80%).2

The safety of PYLARIFY was evaluated in 593 clinical patients who were exposed to a single dose of PYLARIFY and was generally well tolerated. The most common adverse reactions reported in ≤ 2% of patients were headache, dysgeusia and fatigue. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reaction.3

About Prostate Cancer
Prostate cancer is the second most common form of cancer affecting men in the U.S. An estimated 1 in 8 men will be diagnosed in their lifetime. The incidence rate for prostate cancer has been increasing since 2014 at a rate of 3% per year overall. For 2026, estimates suggest nearly 334,000 new cases and more than 36,000 deaths. Prostate cancer can be a serious disease and is the second-leading cause of cancer death in men (behind lung cancer), but most men diagnosed with prostate cancer do not die from it. In fact, more than 3.5 million men in the U.S. consider themselves prostate cancer survivors.4

PYLARIFY TruVu (piflufolastat F 18) Injection
PYLARIFY TruVu (piflufolastat F 18) injection (also known as 18F-DCFPyL or PyL) is a fluorinated small molecule PSMA-targeted PET imaging agent that enables visualization of lymph nodes, bone and soft tissue metastases to determine the presence or absence of recurrent and/or metastatic prostate cancer.1,2

PYLARIFY TruVu was developed to build on the success of PYLARIFY, the number one utilized PSMA PET imaging agent in the U.S. which has been used in over 760,000 scans across 48 states, Puerto Rico and Washington, D.C.5

INDICATION
PYLARIFY (piflufolastat F 18) and PYLARIFY TRUVU (piflufolastat F 18) Injection are indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer:

with suspected metastasis who are candidates for initial definitive therapy.
with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level.
IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS
Risk of Image Misinterpretation
Imaging interpretation errors can occur with PYLARIFY and PYLARIFY TRUVU imaging. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of PYLARIFY and PYLARIFY TRUVU for imaging biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. The performance of PYLARIFY and PYLARIFY TRUVU for imaging of metastatic pelvic lymph nodes prior to initial definitive therapy seems to be affected by risk factors such as Gleason score and tumor stage. PYLARIFY and PYLARIFY TRUVU uptake is not specific for prostate cancer and may occur with other types of cancer as well as non-malignant processes and in normal tissues. Clinical correlation, which may include histopathological evaluation, is recommended.

Hypersensitivity Reactions
Monitor patients for hypersensitivity reactions, particularly those with a history of allergy to other drugs and foods. Reactions may be delayed. Always have trained staff and resuscitation equipment available.

Radiation Risks
PYLARIFY and PYLARIFY TRUVU, expose patients to radiation. Radiation exposure is associated with a dose-dependent increased risk of cancer. Ensure safe handling and preparation procedures to protect patients and health care workers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration.

ADVERSE REACTIONS
The most frequently reported adverse reactions were headaches, dysgeusia and fatigue, occurring at rate of ≤2% during clinical studies. In addition, a delayed hypersensitivity reaction was reported in one patient (0.2%) with a history of allergic reactions.

DRUG INTERACTIONS
Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of PYLARIFY and PYLARIFY TRUVU in prostate cancer. The effect of these therapies on performance of PYLARIFY and PYLARIFY TRUVU PET has not been established.

To report suspected adverse reactions for PYLARIFY or PYLARIFY TRUVU, call 1-800-362-2668 or contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Please see the full Prescribing Information for PYLARIFY and PYLARIFY TRUVU.

"2025 was a transformative year for Immuneering. We reported 64% overall survival at 12 months in first-line pancreatic cancer patients treated with atebimetinib + mGnP, well above the benchmark for GnP standard of care. We designed atebimetinib with three mechanisms well-established to improve survival, and we believe these survival gains are driven by atebimetinib shrinking tumors durably with less resistance, preserving body mass by countering cachexia, and minimizing side effects to maximize combinability and performance status," said Ben Zeskind, Ph.D., Chief Executive Officer of Immuneering. "We also made rapid progress in preparation for our pivotal Phase 3 trial in first-line pancreatic cancer patients, MAPKeeper 301, having secured alignment with both the FDA and EMA on our trial design, and we are on track to dose the first patient mid-year. With cash runway expected into 2029, uniquely encouraging clinical data, and a solid pipeline, we are strongly positioned to deliver on our mission to help patients live longer and feel better."

Recent Corporate Highlights

Reported 64% Overall Survival at 12 Months in First-Line Pancreatic Cancer Patients Treated with Atebimetinib + mGnP: In January, the Company announced positive updated survival and safety data from its ongoing Phase 2a trial of atebimetinib in combination with mGnP in first-line pancreatic cancer patients (N=34), with 13.4 months median follow up. Immuneering reported 64% overall survival (OS) observed at 12 months as of the December 15, 2025 data cutoff date. Atebimetinib (320mg dosed once daily) + mGnP was observed to demonstrate a favorable tolerability profile, with only two categories of adverse events observed at or above the grade 3 level in more than 10% of patients (neutropenia and anemia, both of which are categories commonly observed with standard of care chemotherapy), in comparison to toxicity profiles for other combinations in the front line pancreatic cancer setting, which demonstrate significantly more grade 3 and higher adverse events. No head-to-head clinical trial has been conducted evaluating atebimetinib and other candidates or products. Differences exist between trial designs, subject characteristics and other factors, and caution should be exercised when comparing data across studies.
Secured Alignment with FDA and EMA on pivotal Phase 3 Atebimetinib Trial for First-Line Metastatic Pancreatic Cancer Patients: In December, Immuneering announced that it expected to dose the first patient in its planned global pivotal Phase 3 registrational trial, MAPKeeper 301, in first-line pancreatic cancer patients in mid-2026, evaluating atebimetinib (320 mg QD) in combination with modified gemcitabine and nab-paclitaxel (mGnP), compared with gemcitabine and nab-paclitaxel (GnP) alone. The Company remains on track with this guidance. Notably, the Company completed its End-of-Phase 2 (EOP2) interactions with the U.S. Food and Drug Administration (FDA) and received scientific advice from the European Medicines Agency (EMA). Immuneering achieved alignment with both agencies on the key elements of the proposed Phase 3 trial.
Added to the Nasdaq Biotechnology Index (NBI): On December 22, 2025, Immuneering was added to the Nasdaq Biotechnology Index.

Anticipated Near-Term Milestones

Immuneering is planning for several near-term anticipated milestones related to atebimetinib, including:

Q2 2026: Report updated circulating tumor DNA data on acquired alterations at a major scientific meeting.
1H 2026: Report updated survival data from over 50 first-line pancreatic cancer patients treated with atebimetinib + mGnP.
Mid-2026: Dose first patient in pivotal Phase 3 MAPKeeper clinical trial of atebimetinib + mGnP in first-line pancreatic cancer.
2H 2026: Dose first patient in trial of atebimetinib + Libtayo in RAS-mutant first-line non-small cell lung cancer.

2026 Financial Guidance

Based on cash, cash equivalents and marketable securities as of December 31, 2025, and current operating plans, the Company expects its cash runway to be sufficient to fund operations into 2029.

About Atebimetinib

Atebimetinib is the first in a new category of oral drug candidates, Deep Cyclic Inhibitors (DCIs), designed to improve overall survival by three mechanisms: shrinking tumors durably with less resistance, preserving body mass by countering cachexia, and minimizing side effects to maximize performance status and combinability. Each of these mechanisms has been well established to improve survival in published studies. DCIs challenge the conventional model of sustained or continuous inhibition in oncology. Whereas most therapies are designed for sustained inhibition, driving cancer to adapt and develop resistance so tumors shrink quickly but temporarily, DCIs are designed to pulse faster than tumors can adapt, so tumors shrink slowly but durably. Moreover, DCIs aim to restore full transient signaling to healthy cells, with the goal of leading to fewer adverse events. Atebimetinib targets MEK, a key control point in the MAPK pathway (RAS-RAF-MEK-ERK), which is pathologically activated in a majority of cancers, including approximately 97% of pancreatic cancers. Targeting MEK blocks a broader range of MAPK pathway alterations because it is further downstream, creating the potential for more durable benefit.

The Company believes the topline results are not only positive but decision-grade that should support an end of phase 2 (EOP2) meeting with the FDA in the first half of 2026 as well as accelerate partnering readiness.

SKNJCT-003 Clinical Trial Design and Topline Results:

The SKNJCT-003 clinical study was designed as a randomized, double-blind, placebo-controlled (P-MNA), multi-center study enrolling 90 patients presenting with nodular type BCC of the skin. The study evaluated the safety and efficacy of two dose levels of D-MNA compared to placebo control.

Participants were randomized 1:1:1 into three groups:

Placebo-controlled group receiving P-MNA
Low-dose group receiving 100μg of D-MNA
High-dose group receiving 200μg of D-MNA
The primary endpoint for treatment of BCC is a binary, multi-component endpoint defined as achieving both clinical and histological clearance (i.e. the proportion of patients demonstrating both clinical (visual) clearance and histological clearance (CR) at a prespecified post-treatment timepoint.

The prespecified post-treatment timepoints at the end of the study were:

Day 29 for 47 patients
Day 57 for 43 patients
The Topline results are tabulated below:

Dose # of
patients(n) Day 29 post-treatment # of
patients(n) Day 57 post-treatment
47 Clinical Clearance Histological Clearance (CR) 43 Clinical Clearance Histological Clearance (CR)
Placebo 15 33% 20% 16 38% 38%
100ug D-MNA 17 47% 24% 12 42% 33%
200ug D-MNA 15 40% 27% 15 73% 40%

The dataset demonstrates that clearance rates increased between Day 29 and Day 57, consistent with continued biological activity over time. The 200µg cohort demonstrated the highest observed activity at Day 57, achieving 73% Clinical Clearance and 40% Histological Clearance (CR).

"We are extremely encouraged by these topline results, which not only validate management’s scientific and investment thesis, but also provide what we consider to be decision-grade evidence of clinical activity, particularly at the 200-microgram dose level," said Dr. Raza Bokhari, Executive Chairman & CEO of Medicus.

"The observed increase in clearance rates at Day 57 in the higher-dose cohort reinforces the sustained biological activity of SkinJect and supports advancement into the next stage of development. Importantly, we believe this dataset strengthens our position in ongoing and prospective partnering discussions and may accelerate strategic engagement as we evaluate optimal pathways for value creation."

Clinical Study Report and Regulatory Pathway:

These results reflect the analysis of the primary and key secondary efficacy endpoints. Final compilation of the Clinical Study Report (CSR), including full safety analyses and procedural observations such as post-excisional biopsy site assessments, remains ongoing and is expected to be completed in Q2 2026. The Company does not anticipate material changes to the reported efficacy findings.

The SKNJCT-003 study was not powered for registrational endpoints and no conclusions regarding regulatory approval or the outcome of the planned EOP2 meeting with the FDA can be drawn at this time, there can be no assurance that SKNJCT-003 will be granted regulatory approval from the FDA.

Strategic Focus on Phase 2 De-Risking and Partnering

Medicus’ development strategy is to advance select programs through Phase 2 proof-of-concept and pursue licensing or strategic partnerships with established pharmaceutical companies for late-stage development and commercialization.

The Company continues to assemble decision-grade clinical and regulatory data packages across its portfolio to support this partnering-focused model.

About STAR-LLD

STAR-LLD is a continuous delivery lenalidomide (LLD) in development seeking to expand and replace the standard-of-care for the most common blood cancers, multiple myeloma (MM), and chronic lymphocytic leukemia (CLL). A preclinical proof-of-concept study for subcutaneous STAR-LLD demonstrated that MM tumors caused by human myeloma cells grew 25-fold if untreated, five-fold when treated with daily lenalidomide, and shrank by 80% with STAR-LLD over a single 28-day cycle. The study also showed a 100% overall response rate (ORR) using continuous delivery LLD with 20% of animals in this cohort tumor-free after 100 days; by contrast, there was a 0% ORR in animals treated with a 70% higher dose of lenalidomide given in single daily doses. In addition, a Phase 1b clinical study of six relapsed/refractory MM patients resulted in all patients that received STAR-LLD achieving an objective response (1 CR and 5 PRs); no patients experienced drug-related anemia, neutropenia, leukopenia, or thrombocytopenia greater than grade 2 in up to 12 cycles of therapy. The Phase 1b clinical study concluded that continuous delivery of low dose lenalidomide (STAR-LLD) provides meaningful efficacy and improved tolerability with no grade > 2 drug-related hematologic toxicity.
