Bristol Myers Squibb Receives Positive CHMP Opinion for the Subcutaneous Formulation of Opdivo® (nivolumab) Across Multiple Solid Tumor Indications

On March 28, 2025 Bristol Myers Squibb (NYSE: BMY) reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended approval of a new Opdivo (nivolumab) formulation associated with a new route of administration (subcutaneous use), a new pharmaceutical form (solution for injection) and a new strength (600 mg/vial) (Press release, Bristol-Myers Squibb, MAR 28, 2025, View Source [SID1234651572]). Nivolumab for subcutaneous use co-formulated with recombinant human hyaluronidase (rHuPH20), is indicated across multiple previously approved adult solid tumors as monotherapy, monotherapy maintenance following completion of nivolumab plus Yervoy (ipilimumab) combination therapy, or in combination with chemotherapy or cabozantinib. The CHMP opinion will now be reviewed by the European Commission (EC), which has the authority to approve medicines in the European Union (EU).

"The positive CHMP opinion is an important step forward in the evolution of immuno-oncology and in the potential of subcutaneous nivolumab to help transform the lives of people living with cancer," said Dana Walker, M.D., M.S.C.E., Opdivo global program lead, Bristol Myers Squibb. "We look forward to bringing the same high-quality care that transformed cancer treatment with an administration method that has the potential to improve the patient experience and efficiency of healthcare systems in Europe."

The positive CHMP opinion is based on results from the CheckMate -67T trial, and additional data that demonstrated comparable pharmacokinetics and safety profiles between subcutaneous use of Opdivo and IV Opdivo , in which subcutaneous Opdivo demonstrated noninferiority of C avgd28 (time-averaged Opdivo serum concentration over 28 days) and C minss (trough serum concentration at steady state), the study’s primary endpoints, vs. intravenous (IV) Opdivo in patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC) who have received no more than two prior lines of systemic therapy. The geometric mean ratio (GMR) for C avgd28 was 2.10 (90% CI: 2.00-2.20) and the GMR for C minss was 1.77 (90% CI: 1.63-1.93). Additionally, as a key powered secondary endpoint, the objective response rate (ORR) in the subcutaneous Opdivo arm (n=248) was 24% (95% CI: 19-30), compared with 18% (95% CI: 14-24) in the IV Opdivo arm (n=247), showing that subcutaneous Opdivo has similar efficacy compared to IV Opdivo . The safety profile of subcutaneous Opdivo was consistent with the IV formulation. The pharmacokinetics, efficacy and safety results from CheckMate -67T were presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary Cancers Symposium. Additional safety analyses and patient reported outcomes were presented at the 2024 ASCO (Free ASCO Whitepaper) Annual Meeting and the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress.

In the EU, the EC delivers its final decision within approximately two months following receipt of the CHMP opinion. Once issued, the decision will be applicable to all EU member states as well as in the European Economic Area (EEA) countries Iceland, Norway and Liechtenstein.*

On December 27, 2024, nivolumab and hyaluronidase-nvhy, marketed under the brand name Opdivo Qvantig , was approved by the U.S. Food and Drug Administration (FDA).

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -67T clinical trial.

*Centralized Marketing Authorization does not include approval in the United Kingdom (UK).

About CheckMate -67T

CheckMate -67T is a Phase 3, randomized, open-label, noninferiority trial evaluating subcutaneous administration of Opdivo co-formulated with Halozyme’s proprietary recombinant human hyaluronidase rHuPH20, or subcutaneous nivolumab compared to intravenous (IV) Opdivo , in adult patients with advanced or metastatic clear cell renal cell carcinoma (ccRCC) who received prior systemic therapy. A total of 495 patients were randomized to receive either subcutaneous nivolumab (1,200 mg of nivolumab and 20,000 units of hyaluronidase) every 4 weeks subcutaneously (n = 248), or Opdivo 3 mg/kg every 2 weeks intravenously (n = 247). The coprimary endpoints are time-averaged concentration over 28 days (C avgd28 ) and minimum concentration at steady state (C minss ). The key powered secondary endpoint is overall response rate, as assessed by blinded independent central review.

About Subcutaneous Administration

Subcutaneous administration is delivery of treatment beneath the skin and is an alternative to IV infusion. There are several potential benefits of subcutaneous administration: it may offer the flexibility to provide and receive treatment where it is best for the healthcare provider and patient, may impact infusion chair capacity, and may reduce time spent preparing and administering treatment. It may also simplify administering treatment for patients who have difficult-to-access veins or do not want a port. Subcutaneous treatment has the potential to be administered by a healthcare professional without site of care restrictions.

Select Safety Profile from CheckMate -67T

Serious adverse reactions occurred in 28% of patients receiving subcutaneous nivolumab (n=247). The most frequent serious adverse reactions reported in >1% of patients who received subcutaneous nivolumab were pleural effusion (1.6%), pneumonitis (1.6%), hyperglycemia (1.2%), hyperkalemia (1.2%), hemorrhage (1.2%) and diarrhea (1.2%). The most common adverse reactions (≥10%) in patients treated with subcutaneous nivolumab (n=247) were musculoskeletal pain (31%), fatigue (20%), pruritus (16%), rash (15%), hypothyroidism (12%), diarrhea (11%), cough (11%), and abdominal pain (10%). Fatal adverse reactions occurred in 3 (1.2%) patients who received subcutaneous nivolumab; these included myocarditis, myositis, and colitis complications. Study therapy was discontinued in 10% of patients due to adverse reactions. The safety profile of subcutaneous nivolumab was comparable with the safety profile of IV Opdivo .

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune- mediated adverse reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and YERVOY. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and periodically during treatment with OPDIVO and before each dose of YERVOY. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

OPDIVO and YERVOY can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. In patients receiving OPDIVO monotherapy, immune- mediated pneumonitis occurred in 3.1% (61/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.9%), and Grade 2 (2.1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune- mediated pneumonitis occurred in 7% (31/456) of patients, including Grade 4 (0.2%), Grade 3 (2.0%), and Grade 2 (4.4%). In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune- mediated pneumonitis occurred in 3.9% (26/666) of patients, including Grade 3 (1.4%) and Grade 2 (2.6%). In NSCLC patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, immune- mediated pneumonitis occurred in 9% (50/576) of patients, including Grade 4 (0.5%), Grade 3 (3.5%), and Grade 2 (4.0%). Four patients (0.7%) died due to pneumonitis.

Immune-Mediated Colitis

OPDIVO and YERVOY can cause immune-mediated colitis, which may be fatal. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. In patients receiving OPDIVO monotherapy, immune-mediated colitis occurred in 2.9% (58/1994) of patients, including Grade 3 (1.7%) and Grade 2 (1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated colitis occurred in 25% (115/456) of patients, including Grade 4 (0.4%), Grade 3 (14%) and Grade 2 (8%).

In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune-mediated hepatitis occurred in 7% (48/666) of patients, including Grade 4 (1.2%), Grade 3 (4.9%), and Grade 2 (0.4%).

OPDIVO in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to OPDIVO alone. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. In patients receiving OPDIVO and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% of patients.

Immune-Mediated Endocrinopathies

OPDIVO and YERVOY can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated.

The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received OPDIVO monotherapy or OPDIVO in combination with YERVOY or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions: cardiac/vascular: myocarditis, pericarditis, vasculitis; nervous system: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur; gastrointestinal: pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis; musculoskeletal and connective tissue: myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica; endocrine: hypoparathyroidism; other (hematologic/immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection.

In addition to the immune-mediated adverse reactions listed above, across clinical trials of YERVOY monotherapy or in combination with OPDIVO, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1% of patients unless otherwise specified: nervous system: autoimmune neuropathy (2%), myasthenic syndrome/myasthenia gravis, motor dysfunction; cardiovascular: angiopathy, temporal arteritis; ocular: blepharitis, episcleritis, orbital myositis, scleritis; gastrointestinal: pancreatitis (1.3%); other (hematologic/immune): conjunctivitis, cytopenias (2.5%), eosinophilia (2.1%), erythema multiforme, hypersensitivity vasculitis, neurosensory hypoacusis, psoriasis.

Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, which has been observed in patients receiving OPDIVO and YERVOY, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.

Infusion-Related Reactions

OPDIVO and YERVOY can cause severe infusion-related reactions. Discontinue OPDIVO and YERVOY in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30- minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, infusion-related reactions occurred in 5.1% (28/547) of patients. In MPM patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, infusion-related reactions occurred in 12% (37/300) of patients.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO or YERVOY. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO or YERVOY and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO and YERVOY prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action and findings from animal studies, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and YERVOY and for at least 5 months after the last dose.

Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone

In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Lactation

There are no data on the presence of OPDIVO or YERVOY in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment and for 5 months after the last dose.

Serious Adverse Reactions

In Checkmate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO (n=268). Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. In Checkmate 066, serious adverse reactions occurred in 36% of patients receiving OPDIVO (n=206). Grade 3 and 4 adverse reactions occurred in 41% of patients receiving OPDIVO.

Recent Corporate Highlights

Announced Pre-Clinical Results Signaling Increased Potential for BP1001-A as Treatment for Obesity in Type 2 Diabetes Patients. Scientific evidence suggests that by downregulating growth factor receptor-bound protein 2 (Grb2) expression, BP1001-A could help lower blood glucose level by affecting insulin signaling. In December 2024, Bio-Path reported results from preclinical studies of BP1001-A for obesity demonstrating enhanced insulin sensitivity in myoblast and hepatoma cells. Furthermore, in March 2025, Bio-Path reported preclinical results that BP1001-A attenuated fatty acid-induced insulin resistance and restored insulin sensitivity in muscle progenitor and skeletal muscle fiber cell models. Together these studies signal increased potential for BP1001-A as a treatment for obesity and related metabolic diseases in Type 2 diabetes patients.
Expanded Global Patent Portfolio. In February 2025, Bio-Path announced the receipt of newly issued patents in the United States and New Zealand, and updated investors on the extent of its global intellectual property portfolio. Bio-Path received Notice of Allowance from the United States Patent and Trademark Office for U.S. Patent No. 17/339,366 titled, "P-ethoxy nucleic acids for STAT3 inhibition." The New Zealand Intellectual Property Office has granted Patent No. 741793 titled, "P-ethoxy nucleic acids for liposomal formulation." These new patents build on earlier patents granted that protect the DNAbilize platform technology and the Company’s novel RNAi nanoparticle drugs.
Bio-Path continues to expand its intellectual property portfolio by filing patent applications that are applicable to its technology and business strategy. Bio-Path’s patent portfolio currently includes seven issued patents in the U.S. and 61 issued patents in foreign jurisdictions, providing protection in 26 countries.

"During 2024 and into 2025, we continue to advance our lead investigational drug tuspetinib in combination with venetoclax (VEN) and azacitidine (AZA) for frontline treatment of newly diagnosed acute myeloid leukemia (AML)," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer of Aptose. "Tuspetinib brings favorable safety and broad activity across AML genetic subtypes to the TUS+VEN+AZA triplet therapy, which already has achieved complete remissions (CRs) in difficult-to-treat and underserved TP53-mutated/CK AML and FLT3-wildtype AML patients in our ongoing TUSCANY trial. We look forward to sharing more data as the trial evolves."

Key Corporate Highlights

Tuspetinib Phase 1/2 TUSCANY Trial Well Under Way with Responses Noted – Tuspetinib based TUS+VEN+AZA triplet therapy is being advanced in the TUSCANY Phase 1/2 trial with the goal of creating an improved frontline therapy for newly diagnosed AML patients that is active across diverse AML populations (mutation agnostic triplet frontline therapy), including FLT3-wildtype AML. This activity differentiates TUS from other drugs in development. In January 2025, Aptose announced initiation of dosing in the first TUSCANY trial cohort with the starting dose of 40 mg TUS in combination with standard-of-care doses of VEN+AZA. At 40 mg TUS, the triplet therapy achieved complete remissions (CRs) in difficult-to-treat TP53-muated AML and FLT3-wildtype AML patients, including a measurable residual disease (MRD) negative remission (press release here). In February 2025, amid the promising early results and favorable safety from patients treated at the 40 mg dose level, the Cohort Safety Review Committee (CSRC) monitoring the TUSCANY trial approved escalating to 80 mg TUS in the triplet therapy (press release here). Subjects have now begun treatment at the 80 mg TUS dose level of the triplet therapy and further recruitment is under way. No significant safety concerns have been reported to date, including no prolonged myelosuppression of subjects in remission. This TUS+VEN+AZA triplet therapy study in newly diagnosed AML was supported with robust safety and efficacy data from the TUS single agent dose escalation study and the TUS+VEN doublet APTIVATE study in relapsed or refractory (R/R) AML, both of which were completed during 2024 after treating more than 170 patients.
Financing Activity – During 2024, Aptose completed several financings for a total of approximately $37 million to support the TUS-based TUS+VEN+HMA triplet therapy development for AML. This included a $10 million loan Facility Agreement with Hanmi Pharmaceutical Co. Ltd. ("Hanmi"). Subsequently in March 2025, Hanmi and Aptose executed a Debt Conversion Agreement to convert a portion of the debt into equity, subject to Hanmi owning no more than 19.99% of the issued and outstanding common shares of Aptose. Therefore, an amount of $1.5 million has been converted into 409,063 common shares as of this date. Beyond the $10 million, Aptose and Hanmi are negotiating a new tuspetinib co-development collaboration agreement intended to provide additional funding to accelerate clinical development of tuspetinib. Aptose licensed tuspetinib from Hanmi Pharmaceutical in November 2021.
Aptose Signs CRADA with NCI – In December, Aptose announced that it entered into a Cooperative Research and Development Agreement ("CRADA") with the National Cancer Institute (NCI), part of the National Institutes of Health (press release here). Under the CRADA, the NCI and Aptose will collaborate on the clinical development of TUS, an inhibitor of key signaling kinases involved in myeloid malignancies, in the NCI Cancer Therapy Evaluation Program (CTEP) sponsored myeloMATCH trials employing combinations of targeted therapy for the treatment of molecularly defined AML and myelodysplastic syndromes (MDS) populations. These trials will be conducted by NCI’s National Clinical Trials Network (NCTN), with the participation of the NCI Community Oncology Research Program (NCORP) in the U.S. and Canada.
Aptose Meets Nasdaq Minimum Bid Compliance – Earlier this month, Aptose announced that it received a written notification from the Listing Qualifications Department of The Nasdaq Stock Market, LLC notifying the Company that it is in compliance with Nasdaq’s minimum bid price requirement (press release here). On March 14, 2025, Nasdaq confirmed that, for ten consecutive business days, the closing bid price of the Company’s common shares has been $1.00 per share or greater. Accordingly, the Company has regained compliance with Listing Rule 5550(a)(2). Separately, Aptose is not in compliance with the $2.5 million shareholders equity requirement and is operating under an exception granted by the Nasdaq Hearing Panel, which provides Aptose additional time to regain compliance, although there is no assurance that the Company will successfully achieve full compliance with the Nasdaq shareholders equity requirement.

Research and development expenses decreased by $21.7 million to $15.1 million for year ended December 31, 2024, as compared to $36.8 million for the comparable period in 2023. Changes to the components of our research and development expenses presented in the table above are primarily as a result of the following events:

Program costs for tuspetinib were $9.6 million for the year ended December 31, 2024, compared with $24.9 million for the comparable period in 2023. The lower program costs for tuspetinib in the current year were due to reduced activity in our APTIVATE clinical trial, reduced manufacturing costs, and related expenses. In the comparable period in 2023, Tuspetinib program costs included the healthy volunteer study, which was completed in the same year.
Program costs for luxeptinib decreased by approximately $3.1 million primarily due to lower clinical trial and manufacturing activities.
Program costs for APTO-253 decreased by approximately $59 thousand. This reduction was due to the Company’s decision to discontinue further development of APTO-253.
Personnel-related expenses decreased by $2.1M due to lower headcount 2024.
Stock-based compensation decreased by approximately $1.0 million in the year ended December 31, 2024, primarily due to stock options granted with lower grant date fair values when compared to the options granted in the prior period, coupled with option forfeitures recorded in the current year.

Merck Exercises Option with Abbisko, Giving Company Worldwide Commercialization Rights for Pimicotinib

On March 28, 2025 Merck, a leading science and technology company, reported it has exercised its option with Abbisko Therapeutics Co. Ltd, Shanghai, China for commercialization of pimicotinib in the U.S. and rest of world and will pay Abbisko an option fee of $85 million (Press release, Merck KGaA, MAR 28, 2025, View Source [SID1234651542]). Under the agreement signed in 2023 for the commercialization rights in Mainland China, Hong Kong, Macau, and Taiwan, Merck now holds worldwide commercialization rights for pimicotinib. The companies recently reported positive topline results from the global Phase III MANEUVER study, demonstrating pimicotinib significantly improved the primary endpoint of objective response rate versus placebo (54.0% vs. 3.2% at week 25, p<0.0001) in the treatment of patients with tenosynovial giant cell tumor (TGCT). The companies also will explore pimicotinib in additional indications, such as chronic graft-versus-host disease (cGvHD).

"Today marks a significant milestone in our partnership with Abbisko as we work together to deliver a potentially best-in-class therapy for patients with TGCT around the world," said Andrew Paterson, Chief Marketing Officer for the Healthcare business sector of Merck. "This collaboration underscores our commitment to advancing new treatment options in rare oncology for patients who need them. With this important step forward, we aim to transform the treatment landscape and offer hope to those living with TGCT, who today have very limited treatment options."

TGCT is a non-malignant and often recurring tumor of the joints that can cause high morbidity associated with swelling, pain, stiffness, and limited mobility of the affected joints, significantly impacting daily activities and quality of life in the primarily working-age population that it affects.

If left untreated or in recurrent cases, TGCT can result in irreversible damage to the bone, joint and surrounding tissues. This highlights the need for well-tolerated and effective systemic treatments that can impact tumor growth while relieving the symptoms of the disease.

About MANEUVER

The pivotal Phase III MANEUVER study is a three-part, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of pimicotinib in patients with TGCT, who are eligible for systemic therapy and have not received prior anti-CSF-1/CSF-1R therapy. The study is being conducted in China (n=45), Europe (n=28), and the US and Canada (n=21).

In the double-blind Part 1, 94 patients were randomized 2:1 to receive either 50 mg QD of pimicotinib (n=63) or placebo (n=31) for 24 weeks. The primary endpoint is objective response rate (ORR) at week 25, as measured by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 by blinded independent central review in the intent-to-treat (ITT) population. Secondary endpoints include tumor volume score, active range of motion, stiffness by Numeric Rating Scale (NRS), pain by Brief Pain Inventory (BPI), and physical function measured by Patient-Reported Outcomes Measurement Information System (PROMIS).

After the double-blind Part 1, eligible patients may continue to the open-label Part 2 for up to 24 weeks of dosing, results of which are expected in mid-2025. Patients who complete Part 2 may then enter the open-label extension phase (Part 3) for extended treatment and safety follow-up.

About Pimicotinib (ABSK021)

Pimicotinib (ABSK021), which is being developed by Abbisko Therapeutics, is a novel, orally administered, highly selective and potent small-molecule inhibitor of CSF-1R. Pimicotinib has been granted breakthrough therapy designation (BTD) for the treatment of inoperable TGCT by China National Medical Products Administration (NMPA) and the US Food and Drug Administration (FDA), and priority medicine (PRIME) designation from the European Medicines Agency (EMA).

Havah Therapeutics Announces the Filing of a Patent Application Relating to the Use of HAV-088 for Reducing Tumor Size and Conserving Breast Tissue

On March 27, 2025 Havah Therapeutics, a clinical stage biopharmaceutical company developing innovative therapies for prevention and treatment of breast cancers, reported the filing of a new provisional patent application directed to the use of HAV-088 for treating Ductal Carcinoma In-Situ (Press release, HavaH Therapeutics, MAR 27, 2025, View Source [SID1234651553]).

Backed by human in vivo data demonstrating on-target effect, the patent application covers the potential application of HAV-088, a novel androgen receptor (AR) agonist, in treating hormone receptor positive (HR+) disease.

"The filing of this provisional patent application marks an important step in our broader strategy to strengthen our intellectual property portfolio with additional disease-specific claims," said Matthew Brewer, CEO of Havah Therapeutics. "This week’s release of 20-year survival data from a Mayo Clinic trial showed that just one year of adjuvant therapy with an AR agonist in early breast cancer led to a statistically significant reduction in recurrence or death.

"Endocrine therapy has been the foundation of treatment for hormone receptor-positive cancers for over 40 years, yet few advances have focused on the androgen receptor pathway. HAV-088, through AR agonism, is designed to reduce estrogen-driven gene transcription, thereby lowering estrogen receptor expression and limiting the tumor’s ability to respond to estrogen. Over time, we believe this could offer meaningful benefits to patients whose disease is resistant to standard endocrine therapies."

"The data supporting this provisional patent may represent a significant advancement in the treatment of HR-positive DCIS and builds upon the foundational research conducted by Dr. Wayne Tilley and myself," said Stephen Birrell, MD, PhD, Founder and Chair of Havah’s Clinical Advisory Board.
