"The new and updated results from the Phase 2 ATALANTA-1 study demonstrate that GLPG5101 offers timely treatment with low rates of high-grade toxicities and durable responses for patients with relapsed or refractory MCL," said Marie José Kersten, MD, ATALANTA-1 Principal Investigator and Professor of Hematology at Amsterdam University Medical Center. "The short 7-day vein-to-vein time enabled a low dropout rate and eliminated the need for bridging therapy, allowing more patients to receive treatment who otherwise might not have been able to access CAR T-cell therapy."

Summary of ATALANTA-1 data from the MCL cohort (pooled data across two dose levels):
As of September 2, 2025 (data cut-off date), 26 heavily pretreated MCL patients had undergone leukapheresis and 25 had received an infusion of GLPG5101 (4% dropout rate). Of these, 24 patients received a fresh product, with 23 infused within seven days after apheresis.

Among infused patients (N=24), the objective response rate (ORR) was 100%, with a complete response rate (CRR) of 96%. Duration of response (DOR) and progression-free survival (PFS) rates were both 83% at a median follow-up of 9 months.
9 of 10 (90%) of minimal residual disease (MRD)-evaluable patients were MRD-negative at CR and 7 of 9 MRD-negative patients remained in CR at the time of the data cut-off.
GLPG5101 showed an encouraging safety profile (N=24). The most common Grade ≥ 3 treatment-emergent adverse events were hematologic. No Grade ≥ 3 CRS was observed, and only one case of Grade ≥ 3 ICANS occurred.
GLPG5101 demonstrated robust in vivo CAR T-cell expansion and long-term persistence with an enrichment of early memory phenotypes.
Intention to wind down Galapagos’ cell therapy activities
As announced on October 21, 2025, and following a comprehensive strategic and evaluation and sales process, Galapagos remains focused on the intention to wind down the cell therapy activities. This intention is subject to the conclusion of consultations with works councils in Belgium and the Netherlands, during which Galapagos will continue to operate the business and conduct ongoing clinical studies. Galapagos would still consider any viable proposal to acquire all, or part of the cell therapy business, should such a proposal emerge during the wind down process.

"We are very pleased with the accelerating patient enrollment, the expansion of U.S. clinical sites, and the addition of international clinical sites, which together are enabling broader access to FT819 for patients suffering with lupus," said Bob Valamehr, Ph.D., M.B.A., President and Chief Executive Officer of Fate Therapeutics. "The updated FT819 clinical data continue to demonstrate meaningful and durable responses with the use of less-intensive conditioning chemotherapy and a differentiated safety profile, reinforcing our goal to commence a registrational study for FT819 in 2026 and highlighting the potential of FT819 as an ideal CAR T-cell therapy for various autoimmune diseases. At the same time, our next-generation programs, FT836 and FT839, are showing substantial progress, with enhanced potency, functional persistence, and multifunctional engineering that are designed to extend the benefits of our platform across hematologic malignancies and solid tumors. These advances highlight the continued momentum of our iPSC-derived off-the-shelf CAR T-cell pipeline and our commitment to delivering scalable, on-demand and broadly accessible CAR T-cell therapies worldwide."

The clinical update includes data from the Company’s ongoing Phase 1 basket trial of FT819, its lead product candidate, across 13 enrolled patients; 12 with SLE (10 of whom have at least one month of post-treatment follow-up) and one with systemic sclerosis. The updated results demonstrate sustained clinical responses, durable B-cell depletion in a potential dose-response manner, and a differentiated safety profile without the need for intensive-conditioning chemotherapy that typically consists of multiple days of combined doses of cyclophosphamide and fludarabine. With the strength of this clinical data, the Company continues to advance preparations for a pivotal study and is engaged in discussions with the United States Food and Drug Administration (FDA) under its Regenerative Medicine Advanced Therapy (RMAT) designation regarding plans to initiate registrational trial of FT819 in 2026.

At ASH (Free ASH Whitepaper), the Company also presented new preclinical data for two next-generation iPSC-derived CAR T-cell programs designed for use in both oncology and autoimmunity. These programs demonstrate substantial improvements in functional activity and persistence, drug product consistency and uniformity, and breadth of antigen-targeting mechanisms compared with existing autologous and in vivo CAR T-cell platforms.

FT819-102 Clinical Trial Update

FT819 is an off-the-shelf CD19-targeting chimeric antigen receptor (CAR) T-cell product engineered to improve safety and efficacy. Analogous to master cell lines used to mass produce biopharmaceutical drug products such as monoclonal antibodies, a precisely engineered clonal master iPSC line serves as the starting cell source to manufacture FT819, overcoming numerous limitations associated with patient- and donor-sourced CAR T-cell therapies. FT819 is well-defined and uniform in composition, produced at a low cost of goods, and can be stored in inventory for off-the-shelf, on-demand availability to potentially reach a broad patient population.

As of a November 25, 2025 data cut off date, 12 SLE patients were treated by 5 enrolling clinical sites, with 14 clinical sites in total (11 in United States and 3 in United Kingdom) now activated. Baseline characteristics were consistent with a high disease burden patient population:

median SLE duration was 8.7 years, median 7 prior therapies;
median 14 Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) (baseline range 8-20);
mean 2.3±0.4 Physician Global Assessment (PGA); and
mean 23±13 Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-Fatigue) score.
As of an October 22, 2025 data cut off date, 10 SLE patients had ≥ 1 month follow up, with 6 of the 10 patients having active lupus nephritis. Preliminary data in Regimen A (with patients receiving a single FT819 dose after pretreatment with either a single dose of cyclophosphamide or two doses of bendamustine) show mean SLEDAI-2K score across both dose levels (DL1, 360 million cells; DL2, 900 million cells) decreased progressively from baseline:

DL1 SLEDAI-2K score decreased from a mean of 15.2 (n=5) at baseline to a mean of 10 at month 3 (n=2), and to a mean of 6 at month 6 (n=2), representing mean percent drops of 50% and 70%, respectively; and
DL2 SLEDAI-2K score decreased from a mean of 14.3 (n=3) at baseline to a mean of 6 at month 3 (n=2) and to 4 at month 6 (n=1), representing mean percent drops of 65% and 78%, respectively.
Clinical SLEDAI-2K (excluding anti-dsDNA and complement) of 0 was achieved in 5 out of 10 patients, two of whom had resumed an immunosuppressive agent that had previously failed to achieve a clinical SLEDAI-2K of 0 prior to FT819. Two lupus nephritis patients had greater than 3-month follow up, with both achieving complete renal response (CRR) at 2 months and 6 months, respectively. FACIT-fatigue scores improved meaningfully for all patients who had more than one assessment. B-cell depletion was observed, with reconstitution towards predominately naïve cells within the first 3 months. There were no observed dose limiting toxicities; no Grade >2 CRS, ICANS, or GVHD were reported. All patients were treated with FT819 that was available on-demand.

"These promising clinical data, including multiple complete responses and encouraging initial data for response durability, demonstrate the potential for CLN-049 to expand treatment options for a broad population of people with AML, including patients with TP53-mutated AML who currently face a particularly poor prognosis," said Jeffrey Jones, MD, MBA, Chief Medical Officer, Cullinan Therapeutics. "Coupled with recent Fast Track designation from the FDA, which underscores the promise of CLN-049 to help patients with AML, Cullinan is committed to rapidly advancing this potential new treatment option for a devastating disease."

"Despite advances in select settings, AML remains an aggressive blood cancer with limited options for durable response, particularly for patients with relapsed or refractory disease," said Mohammad Maher Abdul Hay, MD, Director, Clinical Leukemia Program, Perlmutter Cancer Center, and Director, Blood & Marrow Transplantation and Cellular Therapy Program, NYU Langone Health. "CLN-049 represents a novel approach to target AML as it binds to the extracellular domain of FLT3, both wildtype and mutated forms, redirecting a patient’s own T cells to recognize and eliminate leukemic cells. FLT3 is a particularly promising target for this therapeutic approach since it is expressed by AML blasts in more than 80% of patients. The compelling early efficacy including durability data shared today show the potential impact a FLT3-targeted T cell engager could have for AML patients in need of new options."

Efficacy Results

As of the August 2025 data cutoff, 45 patients (39 AML, 3 MDS/AML, and 3 MDS) were enrolled without regard to FLT3 cell surface expression across 8 cohorts (target dose range 1.5-12 µg/kg). 41 patients across 7 cohorts were efficacy evaluable, having reached at least one on-treatment response assessment. Patients with AML had received a median of 2 prior therapies (range: 1-8).

For AML, response was assessed using ELN 2022 criteria. Efficacy endpoints include complete response (CR) rate, composite complete response (CRc) rate (CR/complete remission with incomplete recovery (CRi)/complete remission with partial hematologic recovery (CRh)).

Promising monotherapy activity was observed in heavily pretreated patients with AML at clinically active target doses:

•
At the highest target dose studied thus far of 12 µg/kg (n=16), CR/CRh rate was 31% (5/16) and CRc rate was 31% (5/16).
•
Anti-leukemic activity was observed at target doses ≥6 µg/kg (n=32), with a CR/CRh rate of 25% (8/32) and a CRc rate of 28% (9/32).

Data show promising initial durability in responders, including measurable residual disease (MRD) negativity:

•
At efficacious doses (≥6 µg/kg), in the patients achieving a CR/CRh response, 63% (5/8) of patients had a duration of response of >16 weeks and 2 additional patients were able to proceed to allogeneic hematopoietic stem cell transplant.
•
In 10/32 patients achieving bone marrow blasts <5% at a target dose of ≥6 µg/kg, 30% (n=3) patients were MRD negative by flow cytometry, and 1 MRD-negative patient has had an ongoing response for >36 weeks.

Encouraging responses were observed in difficult-to-treat AML patients with high-risk genetic features:

•
Notably, among the 8 patients with TP53-mutated AML treated at 12 µg/kg, 50% (4/8) of patients achieved a CR/CRh response: 3 patients achieved a CRh response and 1 patient achieved a CR; 3/4 patients with CR/CRh had responses that were durable >16 weeks.
•
Responses were observed in patients with AML independent of baseline FLT3 expression and regardless of baseline genetic risk.

Safety Results

As of the August 2025 data cutoff, the data demonstrate a favorable safety profile in a broad population of patients with R/R AML and MDS (N=45):

•
The most common treatment-emergent adverse events (TEAEs) included cytokine release syndrome (CRS) (35.6%), infusion-related reaction (33.3%), febrile neutropenia (20.0%), white blood cell count decrease and pneumonia (17.8% each), diarrhea, hypomagnesemia, stomatitis, and hypokalemia (15.6% each).
•
Nearly all CRS events limited to Grade 1 or 2, and the majority occurred after a step-up dose (SUD) or target dose 1. No Grade 3 CRS was observed with two step-up doses. CRS did not lead to treatment discontinuation.
•
Grade ≥3 TEAEs occurring in >10% of patients included febrile neutropenia (20.0%), white blood cell count decrease (17.8%), pneumonia and neutrophil count decrease (11.1% each).

CLN-049 development will proceed under FDA Fast Track designation. Dose escalation continues in this ongoing Phase 1 study, with expansion cohorts planned in early 2026.

Live and Virtual Investor Event

Cullinan Therapeutics will host an in-person event for analysts and institutional investors on Monday, December 8, at 8:00 p.m. ET, during which David Sallman, MD, Associate Member, Myeloid Section Head, Moffitt Cancer Center & Research Institute, will participate in a discussion of the CLN-049 data shared at the 2025 ASH (Free ASH Whitepaper) Annual Meeting and Exposition with members of Cullinan Therapeutics management.

About CLN-049

CLN-049 is a novel, investigational FLT3xCD3 bispecific T cell engager. CLN-049 is designed to target FLT3-expressing leukemia cells, offering a new immunotherapeutic approach for treating acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). CLN-049 binds to both mutated and non-mutated FLT3, allowing targeted action regardless of FLT3 mutational status, making the investigational treatment widely applicable to a broad population.

CLN-049 is being studied in a Phase 1, open-label, multicenter, first-in-human, multiple ascending dose study evaluating safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary efficacy of intravenously (IV) administered CLN-049 in patients with relapsed/refractory AML or MDS (NCT05143996) and in a parallel Phase 1, open-label, dose escalation and dose expansion study for the treatment of patients with AML with measurable residual disease (MRD) (EUCT 2023-506572-27-00).

CLN-049 has received Fast Track designation from the U.S. FDA for the treatment of relapsed/refractory AML.

About Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow and the most common form of acute leukemia in adults.1,2 It is characterized by the rapid growth of abnormal white blood cells that crowd out healthy cells, leading to infections, fatigue, and bleeding.3 Each year in the U.S., approximately 22,000 people are diagnosed with AML, and about half as many lives are lost to the disease.4 Globally, AML affects an estimated 144,000 people annually, with approximately 130,000 deaths.5

Despite recent advances, outcomes for patients with AML remain poor, particularly for those with relapsed or refractory disease, where five-year survival is 10% or less.4,6 Patients with high-risk genetic features, such as complex karyotype or TP53 mutations, face especially limited options.7,8 Intensive treatments like chemotherapy and stem cell transplantation may be inaccessible for many older patients due to severe side effects.8 Currently, there are no approved immunotherapies for AML, underscoring the urgent need for novel therapeutic approaches that can improve outcomes for patients and their families facing this life-threatening disease.

On December 8, 2025 Coherus Oncology, Inc. (NASDAQ: CHRS) reported compelling six-year overall survival (OS) follow-up results from the Phase 3 JUPITER-02 trial evaluating LOQTORZI (toripalimab-tpzi) plus chemotherapy in recurrent or metastatic nasopharyngeal carcinoma (RM-NPC). The findings reveal a striking and durable survival advantage that underscores the urgent clinical need to incorporate LOQTORZI with chemotherapy as first-line treatment.

In this exploratory post-hoc analysis, patients receiving LOQTORZI plus gemcitabine and cisplatin achieved a median OS of 64.8 months, nearly double that of chemotherapy alone (33.7 months), representing a 31-month improvement and an observed 38% reduction in risk of death (HR 0.62; 95% CI, 0.45–0.85). These results, presented at ESMO (Free ESMO Whitepaper) Asia 2025, signal a step change in cancer patient survival, reinforcing LOQTORZI’s role in transforming outcomes for people living with RM-NPC.

JUPITER-02 is a randomized, double-blind, placebo-controlled Phase 3 study evaluating LOQTORZI with chemotherapy in first-line RM-NPC, and this long-term follow-up provides additional context for the previously reported survival outcomes.

A Meaningful Shift for Patients Who Need It Most

RM-NPC is an aggressive cancer, and long-term survival with standard chemotherapy can be limited for many patients. The multi-year survival observed in the LOQTORZI arm suggests a potential for meaningful clinical benefit, which may translate into longer survival for patients who typically face a challenging prognosis.

"The new 6-year overall survival follow up data gives us even greater confidence to use toripalimab in patients with NPC that is recurrent or metastatic," said Victoria Villaflor, MD, Professor and Director, Head and Neck Oncology Program, Division of Hematology-Oncology, Department of Medicine, UC Irvine School of Medicine.

For many patients, the difference between 33 months and nearly 65 months represents the possibility of more time with family and more milestones. This meaningful extension highlights why oncologists may consider adding LOQTORZI to chemotherapy upfront, as delaying or omitting a therapy associated with improved survival outcomes could reduce a patient’s opportunity to achieve longer-term benefit.

A Standard of Care Reinforced by Long-Term Evidence

"These data suggest a significant long-term overall survival benefit for patients living with RM-NPC," said Rosh Dias, MD, Chief Medical Officer, Coherus Oncology. "With these long-term data, LOQTORZI, in combination with chemotherapy, reinforces the data supporting this regimen as the standard of care for patients living with RM-NPC."

Coherus Oncology is advancing a pipeline built on deep scientific expertise and strategic collaborations designed to deliver first- and best-in-class therapies. LOQTORZI, Coherus’ next-generation PD-1 inhibitor, is an important part of this vision, with data indicating its potential to enhance survival outcomes when used with chemotherapy.

Abstract # 1279: Long Term Overall Survival Follow-up of Toripalimab versus Placebo in Combination with Gemcitabine and Cisplatin as First-line Treatment for Recurrent or Metastatic Nasopharyngeal Carcinoma

Date: Friday, December 5, 2025, 5:00 p.m. – 6:30 p.m. PST
INDICATIONS AND IMPORTANT SAFETY INFORMATION

INDICATIONS

LOQTORZI (toripalimab-tpzi) is indicated:

In combination with cisplatin and gemcitabine, for the first-line treatment of adults with metastatic or with recurrent, locally advanced nasopharyngeal carcinoma (NPC).
As a single agent, for the treatment of adults with recurrent unresectable or metastatic NPC with disease progression on or after a platinum-containing chemotherapy.
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 can be severe or fatal, occur in any organ system or tissue, affect more than one body system simultaneously, and occur at any time after starting PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment, they can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.

Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. 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 LOQTORZI based on severity and type of reaction (see Dosage and Administration in Prescribing Information). In general, If LOQTORZI requires interruption or discontinuation, 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.
Immune-Mediated Pneumonitis
LOQTORZI can cause immune-mediated pneumonitis.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, immune-mediated pneumonitis occurred in 2.1% (3/146) of patients, including Grade 2 (1.4%) adverse reactions. Pneumonitis resolved in 67% (2/3) of these patients.
In patients receiving LOQTORZI monotherapy, immune-mediated pneumonitis occurred in 2.6% (22/851) of patients, including fatal (0.2%), Grade 3 (0.7%), and Grade 2 (1.1%) adverse reactions. Systemic corticosteroids were required in 82% (18/22) of patients with pneumonitis. Pneumonitis led to permanent discontinuation of LOQTORZI in 1.2% (10/851) of patients. Pneumonitis resolved in 23% (5/22) of these patients.
Immune-Mediated Colitis
LOQTORZI can cause immune-mediated colitis, which may present with 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 LOQTORZI monotherapy, immune-mediated colitis occurred in 0.4% (3/851) of patients, including Grade 3 (0.2%) and Grade 2 (0.1%) adverse reactions. Colitis resolved in all 3 patients.

Hepatotoxicity and Immune-Mediated Hepatitis
LOQTORZI can cause immune-mediated hepatitis.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, immune-mediated hepatitis occurred in 0.7% (1/146) of patients, which was a Grade 3 (0.7%) adverse reaction. The patient with immune-mediated hepatitis required systemic corticosteroids.
In patients receiving LOQTORZI monotherapy, immune-mediated hepatitis occurred in 3.3% (28/851) of patients, including Grade 4 (0.8%), Grade 3 (2.1%), and Grade 2 (0.4%) adverse reactions. Hepatitis led to permanent discontinuation of LOQTORZI in 1.1% of patients and withholding of LOQTORZI in 0.8% of patients. Hepatitis resolved in 54% (15/28) of these patients.
Immune-Mediated Endocrinopathies
Adrenal Insufficiency
LOQTORZI can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold or permanently discontinue LOQTORZI depending on severity. In patients receiving LOQTORZI monotherapy, adrenal insufficiency occurred in 0.5% (4/851) of patients, including Grade 2 (0.4%) and Grade 1 (0.1%) adverse reactions. Systemic corticosteroids were required in 75% (3/4) of the patients with adrenal insufficiency. Adrenal insufficiency led to withholding of LOQTORZI in 0.1% (1/851) of patients. In the one patient in whom LOQTORZI was withheld, LOQTORZI was reinitiated after symptom improvement.

Hypophysitis
LOQTORZI can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effects such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as indicated. Withhold or permanently discontinue LOQTORZI depending on severity. In patients receiving LOQTORZI monotherapy, hypophysitis occurred in 0.4% (3/851) of patients receiving LOQTORZI, including Grade 3 (0.2%) and Grade 2 (0.1%) adverse reactions. All three patients received systemic corticosteroids. Hypophysitis led to permanent discontinuation of LOQTORZI in 0.1% (1/851) of patients and withholding of LOQTORZI in 0.1% (1/851) of patients. The one patient in whom LOQTORZI was withheld reinitiated LOQTORZI.

Thyroid Disorders
LOQTORZI can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue LOQTORZI depending on severity.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, thyroiditis occurred in 2.1% (3/146) of patients receiving LOQTORZI, including Grade 2 (1.4%). Three patients required thyroid hormone replacement therapy. Thyroiditis resolved in one of the 3 patients. Hyperthyroidism occurred in 1.4% (2/146) of patients receiving LOQTORZI in combination with cisplatin and gemcitabine. Hyperthyroidism resolved in these 2 patients. Hypothyroidism occurred in 30% (44/146) of patients receiving LOQTORZI in combination with cisplatin and gemcitabine, including Grade 2 (24%) and Grade 1 (6%). Eighty percent of the 44 patients required thyroid hormone replacement therapy. LOQTORZI was withheld in 2.1% (3/146) of the patients. Of the 3 patients in whom LOQTORZI was withheld, 2 patients reinitiated LOQTORZI.

Diabetes mellitus led to permanent discontinuation in 0.4% of patients. Six of the 8 (75%) patients with diabetes mellitus required long-term insulin therapy.

Immune-Mediated Nephritis with Renal Dysfunction
LOQTORZI can cause immune-mediated nephritis.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, immune-mediated nephritis occurred in 0.7% (1/146) of patients receiving LOQTORZI. The one patient with immune-mediated nephritis (Grade 4) required systemic corticosteroids and nephritis led to discontinuation of LOQTORZI. Nephritis resolved in this patient.
In patients receiving LOQTORZI monotherapy, immune-mediated nephritis occurred in 0.5% (4/851) of patients, including Grade 3 (0.5%) adverse reactions. Nephritis resolved in 75% (3/4) of these patients.
Immune-Mediated Dermatologic Adverse Reactions
LOQTORZI can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), has occurred with PD-1/PD-L1 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes. Withhold or permanently discontinue LOQTORZI depending on severity.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, immune-mediated dermatologic adverse reactions occurred in 8% (12/146) of patients, including Grade 3 (3.4%) and Grade 2 (1.4%) adverse reactions. Systemic corticosteroids were required in 25% (3/12) of the patients with immune-mediated dermatologic adverse reactions. Immune-mediated dermatologic adverse reactions led to permanent discontinuation of LOQTORZI in 2.1% (3) of patients. Immune-mediated dermatologic adverse reactions resolved in 92% (11/12) of these patients.
In patients receiving LOQTORZI monotherapy, immune-mediated dermatologic adverse reactions occurred in 4% (34/851) of patients, including Grade 3 (0.4%) and Grade 2 (1.4%) adverse reactions. Immune-mediated dermatologic adverse reactions led to withholding of LOQTORZI in 0.4% (3) of the patients. Systemic corticosteroids were required in 12% (4/34) of the patients with immune-mediated dermatologic adverse reactions. Immune-mediated dermatologic adverse reactions resolved in 71% (24/34) of these patients.
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 LOQTORZI 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, pericardial effusion
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. Some 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, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss.
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, dermatomyositis
Endocrine: Hypoparathyroidism
Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection, other transplant (including corneal graft) rejection
Infusion-Related Reactions
LOQTORZI can cause severe or life-threatening infusion-related reactions including hypersensitivity and anaphylaxis.

In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, infusion-related reactions have been reported in 4.1% of patients, including Grade 2 (0.7%) reactions.
In patients receiving LOQTORZI monotherapy, infusion-related reactions occurred in 2% of 851 patients, including Grade 3 (0.1%) and Grade 2 (0.6%). LOQTORZI was withheld for one Grade 3 infusion related reaction. Monitor patients for signs and symptoms of infusion-related reactions including rigors, chills, wheezing, pruritus, flushing, rash, hypotension, hypoxemia, and fever. Interrupt or slow the rate of infusion for mild (Grade 1) or moderate (Grade 2) infusion-related reactions. For severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions, stop infusion and permanently discontinue LOQTORZI.
Complications of Allogeneic Hematopoietic Stem Cell Transplant (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 (VOD) 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
LOQTORZI 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 women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with LOQTORZI and for 4 months after the last dose.

Lactation
There are no data on the presence of toripalimab-tpzi in human milk; its effects on the breastfed child, or on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to toripalimab-tpzi are unknown. Because of the potential for serious adverse reactions in breastfed children, advise lactating women not to breastfeed during treatment with LOQTORZI and for 4 months after the last dose.
