Dr. Hing Wong, Founder and CEO, stated, "We are more passionate than ever about our desire to create breakthrough immunotherapeutic treatments for diseases with no known cures, especially pancreatic, ovarian cancer and other age-related diseases. We have received clearance to begin clinical trials in alopecia areata, our first-quality-of-life indication, with one of our lead molecules, HCW9302. In non-human primate studies, HCW9302 is well tolerated at the dose level of effectively expanding regulatory T ("Treg") cells. Our surrogate efficacious marker for HCW9302 in treated patients is the expansion of Treg cells after subcutaneous administration."

Further, Dr. Wong provided insights to the Company’s preclinical programs, adding, "Our preclinical programs are also promising. In the fourth quarter of 2024, the Company revealed its new drug discovery and development platform, with a novel scaffolding or "backbone" of proteins called T-cell Receptor β Chain constant region ("TRBC"). The TRBC drug discovery and development platform leverages the Company’s in-depth knowledge of T cell and natural killer ("NK") cell immunology. The Company has constructed 50 proprietary compounds with the TRBC platform for the treatment of hematologic and solid tumors, virally infected cells, and cellular senescence diseases associated with aging."

Dr. Wong explained, "Our expanded portfolio now includes constructs with immune-cell engagers targeting cell-surface antigens associated with diseased cells and multifunctional immunotherapeutic fusions which improve the performance of immune checkpoint inhibitors. They exhibit remarkably target-specific anti-tumor activity and tolerability in relevant animal models." He continued, "We believe that some of our TRBC-based molecules could be a game-changer for Cell and Gene Based Therapies ("CGTs") by significantly reducing cost and improving the clinical efficacy of engineered effector cells for CGT. Based on preclinical studies, it appears they also support the rapidly developing "in-vivo" CAR-T manufacturing approach for CGT. We are excited to share the data in future scientific publications and invited presentations. We believe that we are uniquely positioned for a strong clinical development pipeline through our own programs and with corporate partnerships."

Business Highlights

Business Development Transactions


The Company’s clinical development strategy is to select certain proprietary molecules for development through out-licensing arrangements and other business development transactions. The Company continually assesses its portfolio of molecules in order to identify potential business development opportunities.

On November 17, 2024, the Company entered an exclusive worldwide licensing agreement with WY Biotech Co. Ltd. ("WY Biotech"), which was amended in 2025. Under the amended agreement, the Company expects to receive $7.0 million in June 2025. The WY Biotech license agreement grants WY Biotech the exclusive, world-wide license to use and apply HCW11-006 for in vivo applications. HCW11-006 is a preclinical drug. Under the terms of the license agreement, the Company has opt-in rights to reclaim the Americas market, including United States, Canada, Central America, and South America, at no cost which may be exercised after WY Biotech completes a Phase 1 clinical trial.

The next major business development program will focus on Immune-Cell Engagers, including T-Cell Engagers. In light of recent transactions demonstrating the strong interest in this class of therapeutics by larger pharmaceutical with the necessary clinical development expertise, the Company intends to develop these molecules through corporate partnering and out-licensing arrangements.

Financing Transactions


In 2024, the Company raised $16.3 million:
o
On February 20, 2024, it raised $2.5 million in a private placement of common stock with officers and directors.
o
In multiple closings throughout 2024, it raised $6.9 million in Senior Notes, which are secured by the Company’s shares of Wugen common stock. The Company received shares of Wugen stock as an upfront licensing fee for the Wugen exclusive worldwide license for some of the Company’s proprietary molecules.
o
On November 18, 2024, the Company entered a $6.9 million securities purchase agreement with an institutional investor, involving a registered direct offering and a concurrent private placement of common stock and warrants.

On February 20, 2025, the Company entered into an Equity Purchase Agreement with Square Gate Capital Master Fund, LLC – Series 4 ("Square Gate"), pursuant to which the Company will have the right, but not the obligation, to sell to Square Gate, and Square Gate will have the obligation to purchase from the Company, up to $20,000,000 (with a potential increase of an additional $20,000,000) worth of the Company’s shares of common stock, at the Company’s sole discretion, over the next 36 months, subject to certain conditions precedent and other limitations.

Compliance with Nasdaq Listing Rules


During 2024, the Company received three deficiency notices from the Listing Staff of The Nasdaq Stock Market (the "Exchange") related to the Company’s stock price of trading shares and the market value of the Company. On March 3, 2025, the Nasdaq Hearings Panel (the "Panel") granted the Company an extension in which to regain compliance with all Nasdaq continued listing rules. As a result of the extension, the Panel granted the Company’s request for continued listing on the Exchange, provided that the Company demonstrates compliance with the Bid Price Rule by April 28, 2025, and all other Exchange continued listing rules by June 15, 2025.

On March 31, 2025, the Company will hold a Special Meeting of the Stockholders to obtain stockholder approval for three proposals critical for the success of the compliance plan presented to the Panel, including a reverse stock split, use of the full line of the Equity Line of Credit, and approval of the terms to convert the Senior Notes issued in 2024 into equity.

Clinical Development Results


On January 28, 2025, the Company received clearance of its IND from the FDA to initiate a first-in-human Phase 1 dose escalation clinical trial to evaluate one of its lead drug candidates, HCW9302, in patients with moderate-to-severe alopecia areata, a common autoimmune disease in humans that currently has no curative FDA approved treatments.

As of December 31, 2024, the Company was required to close the Phase 2 clinical study to evaluate HCW9218 in combination with neoadjuvant chemotherapy in ovarian cancer sponsored by the University of Pittsburgh Medical Center, as required under the Settlement Agreement, due to lack of enrollment.

Financial Results


Revenues: Revenues for the fourth quarters ended December 31, 2023 and 2024 were $1.3 million and $394,804, respectively. Revenues for the years ended December 31, 2023 and 2024 were $2.8 million and $2.6 million, respectively. Revenues in both periods were derived exclusively from the sale of licensed molecules to the Company’s licensee, Wugen. The licensed molecules are one of the components used by Wugen in manufacturing their immunotherapeutic products.

Research and development (R&D) expenses: R&D expenses for the fourth quarters ended December 31, 2023 and 2024 were $2.1 million and $1.0 million, respectively, a decrease of $1.1 million, or 51%. R&D expenses for the years ended December 31, 2023 and 2024 were $7.7 million and $6.4 million, respectively, a decrease of $1.3 million, or 17%. R&D expenses were comparatively higher in the reporting periods of 2023 because there were two ongoing clinical trials to evaluate HCW9218 in cancer indications, and IND-enabling studies required for the IND application for HCW9302, including toxicology studies. For the year ended December 31, 2024, the decrease in R&D expenses compared to the comparable period in 2023 was partially offset by an increase in manufacturing costs for replenishing supply of the high-expressing cell line of HCW9101.

General and administrative (G&A) expenses: G&A expenses for the quarters ended December 31, 2023 and 2024 were $1.7 million and $2.0 million, respectively, an increase of $367,320, or 22%. G&A expenses for the years ended December 31, 2023 and 2024 were $6.8 million and $6.8 million, respectively, an increase of $60,081, or 1%. Changes in G&A expenses reflect cost cutting measures effected by the Company in the second quarter of 2024, offset by increases in professional fees, facilities and office expenses, and financing expenses.

Legal expenses: Legal expenses for the quarter ended December 31, 2023 and 2024 were $2.0 million and $148,949, respectively, a decrease of $1.8 million, or 92%. Legal expenses for the twelve months ended December 31, 2023 and 2024 were $6.6 million and $15.9 million, respectively, an increase of $9.3 million, or 142%. The increase in legal expenses related to preparation of testimony and evidence for the hearing and the hearing itself in connection to the Arbitration with ImmunityBio and its affiliates. On July 13, 2024, the parties entered into a Settlement Agreement and General Release, and the Arbitration and related Complaint were dismissed on December 24, 2024. The Company is engaged in discussions with the law firms involved with this matter to arrange a reasonable payment plan with respect to those legal fees.

Reserve for credit losses and other expenses: In the year ended December 31, 2023, the Company recognized a reserve for credit losses related to a $5.3 million interest reserve deposit that was not refunded as required by the lender after the Company terminated their credit agreement. In the year ended December 31, 2024, the Company recognized a $1.3 million loss resulting from the misdirection of funds held in Company accounts to a fraudulent account controlled by a third party.

Net loss: Net loss for the fourth quarters ended December 31, 2023 and 2024 was $10.7 million and $3.4 million, respectively. Net loss for the years ended December 31, 2023 and 2024 was $25.0 million and $30.0 million, respectively, including legal fees incurred in connection with the Arbitration discussed above.

"I am excited to see the results from the Phase 1 monotherapy study of FOR46 (FG-3246) published in the Journal of Clinical Oncology. This is the first clinical trial targeting CD46 in patients with prostate cancer, and the totality of the data highlights the promising potential of FG-3246 anti-cancer activity, especially when considering the unselected, heavily pre-treated patient population in the trial. The trial results provide key insights into the potential clinical impact of targeting CD46 in the treatment of mCRPC and support its further development in this disease space with high unmet need," said Dr. Rahul Aggarwal, Professor of Medicine at the University of California San Francisco, and Principal Investigator of the study.

"We are looking forward to advancing FG-3246 in the clinic and remain on track for initiating the Phase 2 monotherapy study by mid-2025 as well as disclosing topline results from the combination trial of FG-3246 and enzalutamide in the second half of 2025," added Thane Wettig, Chief Executive Officer of FibroGen. "FG-3246 represents a potential first-in-class, non-PSMA approach to treating mCRPC and we, along with the medical community, are excited about the potential for CD46 to become a next generation target in the prostate cancer treatment paradigm."

This Phase 1 study was a multi-center, first-in-human, open label dose escalation and expansion study evaluating the safety, tolerability, and anti-tumor activity as measured by the decline of prostate-specific antigen (PSA) from baseline, objective tumor response rate in patients with measurable disease, and radiographic progression free survival (rPFS). The completed Phase 1 trial includes a total of 56 patients from the dose-escalation and dose-expansion cohorts. Notably, patients were biomarker unselected and heavily pre-treated, having received a median of 5 lines of therapy prior to receiving FG-3246.

Key highlights from the publication include:

The maximally tolerated dose of FG-3246 was 2.7 mg/kg by adjusted body weight (AjBW) every 3 weeks
The most frequent adverse events were consistent with other MMAE-based ADCs and included infusion related reactions (48.2%), neutropenia (41.1%), and peripheral neuropathy (32.1%).
Ocular adverse events were infrequent, which may be a distinguishing feature compared with other MMAE-based ADCs
Efficacy observed in the RECIST-evaluable set of 25 patients:
Confirmed objective response rate was 20% with median duration of response of 7.5 months
All objective responses observed at a starting dose of 2.7 mg/kg or higher
Disease control rate was 80% with duration of treatment exceeding 24 weeks in 12 patients (48%)
PSA50 response rate of 36% in 39 evaluable patients
Of eight evaluable patients who received docetaxel in the castration-sensitive setting, four (50%) achieved a confirmed PSA50 response
Median radiographic progression-free survival of 8.7 months in all 40 subjects in the efficacy analysis set
Of 15 evaluable baseline tumors, 12 (80%) were positive for CD46 expression by immunohistochemistry
FG-3246 responders were found to have a significantly higher frequency of effector T cells and lower frequency of immunosuppressive myeloid cells
The Company anticipates initiating the Phase 2 monotherapy dose optimization study of FG-3246 in patients with mCRPC by mid-2025.

FG-3246 is also being evaluated in combination with enzalutamide in an investigator-sponsored study with topline results from the Phase 2 portion of the study anticipated in 2H 2025.

About the Phase 1 Study
FOR46-001 (NCT03575819) is a Phase 1, dose-escalation study sponsored by Fortis Therapeutics to evaluate multiple doses of IV-administered FG-3246 (also known as FOR46) in patients with mCRPC who have progressive disease on at least one ARSI, followed by a dose-expansion cohort, to evaluate the safety, tolerability, PK, biological activity, and preliminary evidence of anti-tumor activity of FG-3246 in this patient population.

Thirty-three (33) patients were enrolled in the dose-escalation phase of the study at doses between 0.1 mg/kg and 3.0 mg/kg every three weeks (Q3W), with adjusted body weight dosing (AjBW) used at most dose levels above 2.1 mg/kg. Safety and tolerability of FG-3246 were evaluated in the dose-escalation period of the study.

Twenty-three (23) patients were enrolled in the dose-expansion period of the study; 18 patients with adenocarcinoma mCRPC (Cohort 1) and five patients with neuroendocrine prostate cancer (Cohort 2). All patients in the expansion cohorts were treated at 2.7 mg/kg AjBW to a maximum of 270 mg every three weeks.

The safety profile of FG-3246 was characterized, and anti-tumor activity of FG-3246 in adenocarcinoma patients dosed at ≥ 1.2 mg/kg was evaluated.

About Metastatic Castration-Resistant Prostate Cancer
Prostate cancer is the second most common malignancy in men, contributing significantly to male mortality rates. Approximately 13% of men will be diagnosed with prostate cancer at some point during their lifetime. There are about 65,000 drug treatable mCRPC cases in the U.S. annually and 5-year survival in mCRPC is approximately 30%1.

About FG-3246
FG-3246 (also known as FOR46) is a potential first-in-class, fully human antibody-drug conjugate (ADC), exclusively in-licensed from Fortis Therapeutics, and is being developed by FibroGen for metastatic castration-resistant prostate cancer and other tumor types. FG-3246 binds to an epitope of CD46, a cell receptor target, that induces internalization upon antibody binding, is present at high levels in prostate cancer and other tumor types and demonstrates very limited expression in most normal tissues. FG-3246 is comprised of an anti-CD46 antibody, YS5, linked to the anti-mitotic agent, MMAE, which is a clinically and commercially validated ADC payload. FG-3246 has demonstrated anti-tumor activity in both preclinical and clinical studies. FG-3246 is currently in an ongoing Phase 1/2 study being conducted at UCSF to evaluate it in combination with enzalutamide with topline data from the Phase 2 portion of the study expected in the second half of 2025, and a biomarker trial using a PET biomarker for CD46 using the same antibody backbone. We anticipate the initiation of the Phase 2 monotherapy dose optimization trial in metastatic castration-resistant prostate cancer by mid-2025. FG-3246 is an investigational drug and not approved for marketing by any regulatory authority.

· Withhold or permanently discontinue UNLOXCYT depending on the severity of the adverse reaction (see Dosage and Administration in Prescribing Information). In general, if UNLOXCYT requires interruption or discontinuation, administer systemic corticosteroids (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 reaction is not controlled with corticosteroids.

Immune-Mediated Pneumonitis

· UNLOXCYT can cause immune-mediated pneumonitis. In patients treated with other PD-1/PD-L1–blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 1% (3/223, Grade 2) of patients receiving UNLOXCYT.

Immune-Mediated Colitis

· UNLOXCYT can cause immune-mediated colitis, which may present with diarrhea, abdominal pain, and lower gastrointestinal bleeding. Cytomegalovirus infection/reactivation has occurred in patients with corticosteroid-refractory immune-mediated colitis treated with PD-1/PD-L1–blocking antibodies. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 0.4% (1/223, Grade 1) of patients receiving UNLOXCYT.

Immune-Mediated Hepatitis

· UNLOXCYT can cause immune-mediated hepatitis.

Immune-Mediated Endocrinopathies

Adrenal Insufficiency

· UNLOXCYT can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment per institutional guidelines, including hormone replacement as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity. Adrenal insufficiency occurred in 0.9% (2/223) of patients receiving UNLOXCYT, including Grade 2 in 0.4% (1/223) of patients.

Hypophysitis

· UNLOXCYT can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field cuts. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity.

Thyroid Disorders

· UNLOXCYT can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement or medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity. Hypothyroidism occurred in 10% (22/223) of patients receiving UNLOXCYT, including Grade 2 in 5% (10/223) of patients. Hyperthyroidism occurred in 5% (12/223) of patients receiving UNLOXCYT, including Grade 2 in 0.4% (1/223) of patients.

Type 1 Diabetes Mellitus, Which Can Present with Diabetic Ketoacidosis

· UNLOXCYT can cause type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity.

Immune-Mediated Nephritis with Renal Dysfunction

· UNLOXCYT can cause immune-mediated nephritis.

Immune-Mediated Dermatologic Adverse Reactions

· UNLOXCYT can cause immune-mediated rash or dermatitis. Bullous and exfoliative dermatitis, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug rash with eosinophilia and systemic symptoms (DRESS), have occurred with PD-1/PD-L1–blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-bullous/exfoliative rashes. Withhold or permanently discontinue UNLOXCYT depending on severity. Immune-mediated dermatologic adverse reactions occurred in 7% (15/223) of patients receiving UNLOXCYT, including Grade 3 in 0.9% (2/223) of patients and Grade 2 in 4% (9/223) of patients.

Other Immune-Mediated Adverse Reactions

· The following clinically significant immune-mediated adverse reactions occurred in <1% of the 223 patients who received UNLOXCYT 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-Barre syndrome, nerve paresis, autoimmune neuropathy.
- Ocular: Uveitis, iritis, other ocular inflammatory toxicities. Some cases can be associated with retinal detachment. Various grades of visual impairment to include blindness can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss.
- Gastrointestinal: Pancreatitis, including 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): Autoimmune hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenia, solid organ transplant rejection, other transplant (including corneal graft) rejection.

· Monitor patients for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion or permanently discontinue UNLOXCYT based on severity of reaction. Consider premedication with an antipyretic and/or an antihistamine for patients who have had previous systemic reactions to infusions of therapeutic proteins.

Complications of Allogeneic HSCT

· Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1–blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1–blocking antibody prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

· Based on its mechanism of action, UNLOXCYT can cause fetal harm when administered to a pregnant woman. Animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-mediated rejection of the developing fetus, resulting in fetal death. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with UNLOXCYT and for 4 months after the last dose.

Common Adverse Reactions

The most common adverse reactions (≥10%) were fatigue, musculoskeletal pain, rash, diarrhea, hypothyroidism, constipation, nausea, headache, pruritus, edema, localized infection, and urinary tract infection.

Bristol Myers Squibb Receives Positive CHMP Opinion for Perioperative Regimen of Neoadjuvant Opdivo® (nivolumab) and Chemotherapy Followed by Surgery and Adjuvant Opdivo for Resectable Non-Small Cell Lung Cancer in Patients with Tumor Cell PD-L1…

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 Opdivo (nivolumab), in combination with platinum-based chemotherapy as neoadjuvant treatment, followed by Opdivo as monotherapy as adjuvant treatment after surgical resection for the treatment of resectable non-small cell lung cancer (NSCLC) at high risk of recurrence in adult patients whose tumors have PD-L1 expression ≥1% (Press release, Bristol-Myers Squibb, MAR 28, 2025, View Source;/default.aspx [SID1234651573]). The CHMP adopted a positive opinion based on results from the CheckMate -77T trial, in which the perioperative regimen of neoadjuvant Opdivo with chemotherapy followed by surgery and adjuvant Opdivo monotherapy demonstrated statistically significant and clinically meaningful improvement in event-free survival (EFS), the study’s primary endpoint. The European Commission (EC), which has the authority to approve medicines for the European Union (EU), will now review the CHMP recommendation.

"Preventing disease recurrence and improving long-term outcomes for patients with NSCLC earlier in the treatment journey is critical to addressing unmet needs and is one of our top priorities," said Dana Walker, M.D., M.S.C.E., vice president, Opdivo global program lead, Bristol Myers Squibb. "With today’s positive opinion from the CHMP, we are pleased that our second Opdivo -based regimen for certain patients with resectable NSCLC whose tumors have PD-L1 expression ≥1%, is one step closer to being approved in the European Union."

The CheckMate -77T trial also demonstrated clinically meaningful improvements in the secondary efficacy endpoints of pathologic complete response (pCR) and major pathologic response (MPR). The safety profile of the perioperative regimen was consistent with previously reported studies in NSCLC. The EFS, pCR and MPR results from the CheckMate -77T trial were first presented at the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2023 and published in The New England Journal of Medicine . CheckMate -77T is ongoing to assess another key secondary endpoint of overall survival (OS).

In October 2024, the CheckMate -77T trial was used as the basis for the U.S. Food and Drug Administration’s (FDA) approval of Opdivo for the treatment of adult patients with resectable (tumors ≥4 cm or node positive) NSCLC and no known epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) rearrangements, for neoadjuvant treatment, in combination with platinum-doublet chemotherapy, followed by single-agent Opdivo as adjuvant treatment after surgery.

CheckMate -77T represents the company’s second positive Phase 3 randomized trial with an immunotherapy-based combination for the treatment of resectable non-metastatic NSCLC. Opdivo is the only immunotherapy treatment with Phase 3 data in both the neoadjuvant only and perioperative NSCLC treatment setting. In addition, Opdivo and Opdivo -based combinations have shown improved efficacy in the neoadjuvant or adjuvant treatment of four tumor types: lung cancer, bladder cancer, esophageal/gastroesophageal junction cancer and melanoma.

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.

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -77T clinical trial.

About CheckMate -77T
CheckMate -77T is a Phase 3 randomized, double-blind, placebo-controlled, multi-center trial evaluating neoadjuvant Opdivo with chemotherapy followed by surgery and adjuvant Opdivo versus neoadjuvant placebo plus chemotherapy followed by surgery and adjuvant placebo in 461 patients with resectable stage IIA to IIIB NSCLC. The primary endpoint of the trial is EFS. Secondary endpoints include OS, pathologic complete response and major pathologic response.

About Lung Cancer
Lung cancer is the leading cause of cancer deaths globally. Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer, representing up to 84% of diagnoses. Non-metastatic cases account for the majority of NSCLC diagnoses (approximately 60%, with up to half of these being resectable), and the proportion is expected to grow over time with enhanced screening programs. While many non-metastatic NSCLC patients are cured by surgery, 30% to 55% develop recurrence and die of their disease despite resection, contributing to a need for treatment options administered before surgery (neoadjuvant) and/or after surgery (adjuvant) to improve long-term outcomes.

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 .

Other Immune-Mediated Adverse Reactions

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 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.
