About HyBryte

HyBryte (research name SGX301) is a novel, first-in-class, photodynamic therapy utilizing safe, visible light for activation. The active ingredient in HyBryte is synthetic hypericin, a potent photosensitizer that is topically applied to skin lesions that is taken up by the malignant T-cells, and then activated by safe, visible light approximately 24 hours later. The use of visible light in the red-yellow spectrum has the advantage of penetrating more deeply into the skin (much more so than ultraviolet light) and therefore potentially treating deeper skin disease and thicker plaques and lesions. This treatment approach avoids the risk of secondary malignancies (including melanoma) inherent with the frequently employed DNA-damaging drugs and other phototherapy that are dependent on ultraviolet exposure. Combined with photoactivation, hypericin has demonstrated significant anti-proliferative effects on activated normal human lymphoid cells and inhibited growth of malignant T-cells isolated from CTCL patients. In a published Phase 2 clinical study in CTCL, patients experienced a statistically significant (p=0.04) improvement with topical hypericin treatment whereas the placebo was ineffective. HyBryte has received orphan drug and fast track designations from the U.S. Food and Drug Administration (FDA), as well as orphan designation from the European Medicines Agency (EMA).

The published Phase 3 FLASH trial enrolled a total of 169 patients (166 evaluable) with Stage IA, IB or IIA CTCL. The trial consisted of three treatment cycles. Treatments were administered twice weekly for the first 6 weeks and treatment response was determined at the end of the 8th week of each cycle. In the first double-blind treatment cycle (Cycle 1), 116 patients received HyBryte treatment (0.25% synthetic hypericin) and 50 received placebo treatment of their index lesions. A total of 16% of the patients receiving HyBryte achieved at least a 50% reduction in their lesions (graded using a standard measurement of dermatologic lesions, the CAILS score) compared to only 4% of patients in the placebo group at 8 weeks (p=0.04) during the first treatment cycle (primary endpoint). HyBryte treatment in this cycle was safe and well tolerated.

In the second open-label treatment cycle (Cycle 2), all patients received HyBryte treatment of their index lesions. Evaluation of 155 patients in this cycle (110 receiving 12 weeks of HyBryte treatment and 45 receiving 6 weeks of placebo treatment followed by 6 weeks of HyBryte treatment), demonstrated that the response rate among the 12-week treatment group was 40% (p<0.0001 vs the placebo treatment rate in Cycle 1). Comparison of the 12-week and 6-week treatment responses also revealed a statistically significant improvement (p<0.0001) between the two timepoints, indicating that continued treatment results in better outcomes. HyBryte continued to be safe and well tolerated. Additional analyses also indicated that HyBryte is equally effective in treating both plaque (response 42%, p<0.0001 relative to placebo treatment in Cycle 1) and patch (response 37%, p=0.0009 relative to placebo treatment in Cycle 1) lesions of CTCL, a particularly relevant finding given the historical difficulty in treating plaque lesions in particular.

The third (optional) treatment cycle (Cycle 3) was focused on safety and all patients could elect to receive HyBryte treatment of all their lesions. Of note, 66% of patients elected to continue with this optional compassionate use / safety cycle of the study. Of the subset of patients that received HyBryte throughout all 3 cycles of treatment, 49% of them demonstrated a positive treatment response (p<0.0001 vs patients receiving placebo in Cycle 1). Moreover, in a subset of patients evaluated in this cycle, it was demonstrated that HyBryte is not systemically available, consistent with the general safety of this topical product observed to date. At the end of Cycle 3, HyBryte continued to be well tolerated despite extended and increased use of the product to treat multiple lesions.

Overall safety of HyBryte is a critical attribute of this treatment and was monitored throughout the three treatment cycles (Cycles 1, 2 and 3) and the 6-month follow-up period. HyBryte’s mechanism of action is not associated with DNA damage, making it a safer alternative than currently available therapies, all of which are associated with significant, and sometimes fatal, side effects. Predominantly these include the risk of melanoma and other malignancies, as well as the risk of significant skin damage and premature skin aging. Currently available treatments are only approved in the context of previous treatment failure with other modalities and there is no approved front-line therapy available. Within this landscape, treatment of CTCL is strongly motivated by the safety risk of each product. HyBryte potentially represents the safest available efficacious treatment for CTCL. With very limited systemic absorption, a compound that is not mutagenic and a light source that is not carcinogenic, there is no evidence to date of any potential safety issues.

Following the first Phase 3 study of HyBryte for the treatment of CTCL, the FDA and the EMA indicated that they would require a second successful Phase 3 trial to support marketing approval. With agreement from the EMA on the key design components, the second, confirmatory study, called FLASH2, is expected to be initiated before the end of 2024. This study is a randomized, double-blind, placebo-controlled, multicenter study that will enroll approximately 80 subjects with early-stage CTCL. The FLASH2 study replicates the double-blind, placebo-controlled design used in the first successful Phase 3 FLASH study that consisted of three 6-week treatment cycles (18 weeks total), with the primary efficacy assessment occurring at the end of the initial 6-week double-blind, placebo-controlled treatment cycle (Cycle 1). However, this second study extends the double-blind, placebo-controlled assessment to 18 weeks of continuous treatment (no "between-Cycle" treatment breaks) with the primary endpoint assessment occurring at the end of the 18-week timepoint. In the first Phase 3 study, a treatment response of 49% (p<0.0001 vs patients receiving placebo in Cycle 1) was observed in patients completing 18 weeks (3 cycles) of therapy. In this second study, all important clinical study design components remain the same as in the first FLASH study, including the primary endpoint and key inclusion-exclusion criteria. The extended treatment for a continuous 18 weeks in a single cycle is expected to statistically demonstrate HyBryte’s increased effect over a more prolonged, "real world" treatment course. Given the extensive engagement with the CTCL community, the esteemed Medical Advisory Board and the previous trial experience with this disease, accelerated enrollment in support of this study is anticipated, including the potential to enroll previously identified and treated HyBryte patients from the FLASH study. Discussions with the FDA on an appropriate study design remain ongoing. While collaborative, the agency has expressed a preference for a longer duration comparative study over a placebo-controlled trial. Given the shorter time to potential commercial revenue and the similar trial design to the first FLASH study afforded by the EMA accepted protocol, this study is being initiated. At the same time, discussions with the FDA will continue on potential modifications to the development path to adequately address their feedback.

In addition, the FDA awarded an Orphan Products Development grant to support the evaluation of HyBryte for expanded treatment in patients with early-stage CTCL, including in the home use setting. The grant, totaling $2.6 million over 4 years, was awarded to the University of Pennsylvania that was a leading enroller in the Phase 3 FLASH study. Additional supportive studies have demonstrated the utility of longer treatment times (Study RW-HPN-MF-01), the lack of significant systemic exposure to hypericin after topical application (Study HPN-CTCL-02) and its relative efficacy and tolerability compared to Valchlor (Study HPN-CTCL-04).

About Cutaneous T-Cell Lymphoma (CTCL)

CTCL is a class of non-Hodgkin’s lymphoma (NHL), a type of cancer of the white blood cells that are an integral part of the immune system. Unlike most NHLs which generally involve B-cell lymphocytes (involved in producing antibodies), CTCL is caused by an expansion of malignant T-cell lymphocytes (involved in cell-mediated immunity) normally programmed to migrate to the skin. These malignant cells migrate to the skin where they form various lesions, typically beginning as patches and may progress to raised plaques and tumors. Mortality is related to the stage of CTCL, with median survival generally ranging from about 12 years in the early stages to only 2.5 years when the disease has advanced. There is currently no cure for CTCL. Typically, CTCL lesions are treated and regress but usually return either in the same part of the body or in new areas.

CTCL constitutes a rare group of NHLs, occurring in about 4% of the more than 1.7 million individuals living with the disease in the United States and Europe (European Union and United Kingdom). It is estimated, based upon review of historic published studies and reports and an interpolation of data on the incidence of CTCL that it affects approximately 31,000 individuals in the U.S. (based on SEER data, with approximately 3,200 new cases seen annually) and approximately 38,000 individuals in Europe (based on ECIS prevalence estimates, with approximately 3,800 new cases annually).

"Given the rates of disease recurrence in patients with resectable NSCLC, there is a clear need for options that can be administered before and after surgery that may target micrometastasis, help reduce the risk of cancer returning and improve the chance of successful surgical treatment," said Tina Cascone, MD, PhD, associate professor of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center. 2,3,4 "This approval is a step forward for patients with resectable disease, as the perioperative nivolumab plus neoadjuvant chemotherapy regimen can offer an improved event free survival (EFS) compared with neoadjuvant chemotherapy alone and has the potential for achieving a pathologic response (pCR) in one in four patients." 2

The CheckMate-77T trial evaluated the perioperative regimen of neoadjuvant Opdivo with platinum-doublet chemotherapy followed by surgery and adjuvant Opdivo monotherapy (n=229), compared to neoadjuvant platinum-doublet chemotherapy and placebo followed by surgery and adjuvant placebo (n=232) in adult patients with resectable NSCLC. 2 In the trial, the Opdivo arm improved EFS, a primary endpoint, compared to the chemotherapy and placebo treatment arm. 2 A high pCR rate was also observed as one of the pre-specified secondary endpoints. 2

The risk of disease recurrence, progression or death was reduced by 42% (EFS Hazard Ratio [HR] 0.58; 95% Confidence Interval [CI]: 0.43 to 0.78; P =0.00025) in patients treated in the Opdivo arm, compared to the chemotherapy and placebo arm, with a median follow-up of 25.4 months. 2 In addition, 18-month EFS was demonstrated in 70% of patients in the Opdivo arm, compared to 50% of patients in the chemotherapy and placebo arm. 2 Furthermore, 25% of patients in the Opdivo arm achieved pCR, while 4.7% of patients in the comparator arm achieved pCR in the intent-to-treat population (estimated treatment difference of 20.5%; 95% CI,14.3 to 26.6). 2

Opdivo is associated with the following Warnings & Precautions: severe and fatal immune-mediated adverse reactions, including pneumonitis, colitis, hepatitis and hepatotoxicity, endocrinopathies, dermatologic adverse reactions, nephritis and renal dysfunction; infusion-related reactions; complications of allogeneic hematopoietic stem cell transplantation (HSCT); embryo-fetal toxicity. 1 Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue and dexamethasone is not recommended outside of controlled clinical trials. 1 Please see Important Safety Information below.

"This milestone expands the role of Opdivo -based treatments and builds upon the foundation set by the FDA approval of neoadjuvant-only Opdivo plus chemotherapy in resectable NSCLC based on the CheckMate-816 trial," said Wendy Short Bartie, senior vice president of U.S. Oncology and Hematology at Bristol Myers Squibb. 1 "With this new Opdivo -based regimen, we are reinforcing our commitment to helping improve patient outcomes and expanding our thoracic portfolio in early-stage disease."

The recommended dose for Opdivo in this indication is 360 mg with platinum-doublet chemotherapy on the same day every three weeks for up to four cycles or until disease progression or unacceptable toxicity, then continued as a single-agent Opdivo 480 mg every four weeks after surgery for up to 13 cycles (approximately one year) or until disease recurrence or unacceptable toxicity. 1 The FDA previously approved Opdivo for adult patients with resectable (tumors ≥4 cm or node positive) NSCLC in the neoadjuvant setting, in combination with platinum-doublet chemotherapy. 1 Opdivo and Opdivo -based combinations have been approved by the FDA in the neoadjuvant, adjuvant or perioperative settings across four cancers to date, including lung cancer, melanoma, bladder cancer and esophageal/gastroesophageal junction cancer. 1

About CheckMate-77T

CheckMate-77T is a Phase 3 randomized, double-blind, multi-center trial evaluating neoadjuvant Opdivo in combination with platinum-doublet chemotherapy followed by surgery and single-agent adjuvant Opdivo, compared to neoadjuvant platinum-doublet chemotherapy and placebo followed by surgery and adjuvant placebo in patients with resectable NSCLC. 5

In the CheckMate-77T study, a total of 461 patients were randomized to receive either neoadjuvant Opdivo 360 mg with platinum-doublet chemotherapy every three weeks, or placebo and platinum-doublet chemotherapy every three weeks, until disease progression or unacceptable toxicity, for up to four cycles, followed by single-agent Opdivo 480 mg after surgery every four weeks or placebo every four weeks, until disease progression or unacceptable toxicity, for up to thirteen cycles (approximately one year). 1 The primary endpoint of the trial is event-free survival determined by Blinded Independent Central Review (BICR). Secondary endpoints of the trial include pathologic complete response and major pathologic response, both determined by Blinded Independent Pathological Review (BIPR), as well as overall survival and safety. 2

Select Safety Profile from CheckMate-77T

The most common adverse reactions (reported in ≥20%) in patients receiving Opdivo in combination with chemotherapy (n= 228) were anemia (39.5%), constipation (32.0%), nausea (28.9%), fatigue (28.1%), alopecia (25.9%), and cough (21.9%). 6

Serious adverse reactions occurred in 21% of patients who received Opdivo in combination with platinum-doublet chemotherapy as neoadjuvant treatment (n=228). 1 The most frequent (≥2%) serious adverse reaction was pneumonia. 1 Fatal adverse reactions occurred in 2.2% of patients, due to cerebrovascular accident, COVID-19 infection, hemoptysis, pneumonia, and pneumonitis (0.4% each). 1

In Checkmate 77T, 5.3% (n=12) of the OPDIVO-treated patients who received neoadjuvant treatment, did not receive surgery due to adverse reactions. The adverse reactions that led to cancellation of surgery in OPDIVO-treated patients were cerebrovascular accident, pneumonia, and colitis/diarrhea (2 patients each) and acute coronary syndrome, myocarditis, hemoptysis, pneumonitis, COVID-19, and myositis (1 patient each).

Serious adverse reactions occurred in 22% of the patients who received single-agent Opdivo as adjuvant treatment (n=142). 1 The most frequent serious adverse reaction was pneumonitis/ILD (2.8%). 1 One fatal adverse event due to COVID-19 occurred. 1 The perioperative regimen had a safety profile consistent with previously reported Opdivo studies in NSCLC and no new safety signals were identified. 2

About Lung Cancer

Lung cancer is the leading cause of cancer deaths in the United States. 7 The two main types of lung cancer are non-small cell and small cell. 7 Non-small cell lung cancer (NSCLC) represents up to 85% of diagnoses. 7 For some non-metastatic early-stage NSCLC patients, surgery may be able to be used as a singular option for treatment. 8 However, 30% to 55% of patients can develop recurrence, contributing to a need for treatment options administered before surgery (neoadjuvant) and after surgery (adjuvant) to improve long-term outcomes. 2 Survival rates vary depending on the stage and type of the cancer when diagnosed. 7

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. Early identification and management are essential to ensure safe use of OPDIVO. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment with OPDIVO. 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 depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO 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 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%).

Immune-Mediated Colitis

OPDIVO can cause immune-mediated colitis. 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%).

Immune-Mediated Hepatitis and Hepatotoxicity

OPDIVO can cause immune-mediated hepatitis. In patients receiving OPDIVO monotherapy, immune-mediated hepatitis occurred in 1.8% (35/1994) of patients, including Grade 4 (0.2%), Grade 3 (1.3%), and Grade 2 (0.4%).

Immune-Mediated Endocrinopathies

OPDIVO 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 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.

In patients receiving OPDIVO monotherapy, adrenal insufficiency occurred in 1% (20/1994), including Grade 3 (0.4%) and Grade 2 (0.6%).

In patients receiving OPDIVO monotherapy, hypophysitis occurred in 0.6% (12/1994) of patients, including Grade 3 (0.2%) and Grade 2 (0.3%).

In patients receiving OPDIVO monotherapy, thyroiditis occurred in 0.6% (12/1994) of patients, including Grade 2 (0.2%).

In patients receiving OPDIVO monotherapy, hyperthyroidism occurred in 2.7% (54/1994) of patients, including Grade 3 (<0.1%) and Grade 2 (1.2%).

In patients receiving OPDIVO monotherapy, hypothyroidism occurred in 8% (163/1994) of patients, including Grade 3 (0.2%) and Grade 2 (4.8%).

In patients receiving OPDIVO monotherapy, diabetes occurred in 0.9% (17/1994) of patients, including Grade 3 (0.4%) and Grade 2 (0.3%), and 2 cases of diabetic ketoacidosis.

Immune-Mediated Nephritis with Renal Dysfunction

OPDIVO can cause immune-mediated nephritis. In patients receiving OPDIVO monotherapy, immune-mediated nephritis and renal dysfunction occurred in 1.2% (23/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.5%), and Grade 2 (0.6%).

Immune-Mediated Dermatologic Adverse Reactions

OPDIVO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug rash with eosinophilia and systemic symptoms (DRESS) has occurred with PD-1/PD-L1 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate nonexfoliative rashes.

Withhold or permanently discontinue OPDIVO depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information).

In patients receiving OPDIVO monotherapy, immune-mediated rash occurred in 9% (171/1994) of patients, including Grade 3 (1.1%) and Grade 2 (2.2%).

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 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.

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, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.

Infusion-Related Reactions

OPDIVO can cause severe infusion-related reactions. Discontinue OPDIVO 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.

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. 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 and allogeneic HSCT.

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

Embryo-Fetal Toxicity

Based on its mechanism of action and findings from animal studies, OPDIVO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO 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

On October 3, 2024 AstraZeneca reported that supplemental New Drug Application (sNDA) for Calquence (acalabrutinib) has been accepted and granted Priority Review in the US for the treatment of adult patients with previously untreated mantle cell lymphoma (MCL) (Press release, AstraZeneca, OCT 3, 2024, View Source [SID1234647007]).

The Food and Drug Administration (FDA) grants Priority Review to applications for medicines that, if approved, would offer significant improvements over available options by demonstrating safety or efficacy improvements, preventing serious conditions or enhancing patient compliance.1 The Prescription Drug User Fee Act date, the FDA action date for their regulatory decision, is anticipated during the first quarter of 2025.

MCL is a rare and typically aggressive form of non-Hodgkin lymphoma (NHL), resulting when B-lymphocytes mutate into malignant cells within a region of the lymph node known as the mantle zone.2,3 The disease is often diagnosed at advanced stages and remains largely incurable. It is estimated that there are more than 27,500 people living with MCL worldwide.4,5

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: "Today’s Priority Review acceptance reinforces the potential of Calquence to transform outcomes in untreated mantle cell lymphoma. Data from the ECHO trial showed Calquence plus chemoimmunotherapy significantly delayed disease progression and showed a trend to improved survival in patients with this currently incurable blood cancer. We are working closely with the FDA to provide patients this potential new treatment as soon as possible."

The sNDA is being reviewed under Project Orbis, an initiative of the FDA which provides a framework for concurrent submission and review of oncology medicines among participating international partners to bring cancer treatments to patients around the world as early as possible.

Results from the ECHO Phase III trial recently were presented during the late-breaking oral session at the European Hematology Association (EHA) (Free EHA Whitepaper) 2024 Hybrid Congress.

In the trial, Calquence plus bendamustine and rituximab reduced the risk of disease progression or death by 27% compared to standard-of-care (SoC) chemoimmunotherapy (hazard ratio [HR] 0.73; 95% confidence interval [CI] 0.57-0.94; p=0.016). The addition of Calquence to SoC provided almost 1.5 years of additional median progression free survival (mPFS) with mPFS of 66.4 months for patients treated with the Calquence combination versus 49.6 months with SoC.

Overall survival (OS) showed a favourable trend for the Calquence combination compared to SoC chemoimmunotherapy (HR 0.86; 95% CI 0.65-1.13; p=0.2743). The OS trend was sustained over time, although most patients in the SoC arm who needed subsequent therapy received a BTK inhibitor, mainly Calquence. The OS data were not mature at the time of this analysis, and the trial will continue to assess OS as a key secondary endpoint.

The ECHO trial was conducted during the COVID-19 pandemic, and prespecified PFS and OS analyses censoring for COVID-19 deaths were conducted to assess the impact of COVID-19 on the study outcome in alignment with FDA. After censoring for COVID-19 deaths, the PFS was further improved in both arms, with the Calquence combination reducing the risk of disease progression or death by 36% (HR 0.64; 95% CI; 0.48-0.84; p=0.0017). A favourable trend was seen for OS in this analysis for the Calquence combination, but OS data were not mature at the time of this analysis (HR 0.75; 95% CI 0.53-1.04; p=0.0797).

The safety and tolerability of Calquence was consistent with its known safety profile, and no new safety signals were identified.

Notes

MCL
While MCL patients initially respond to treatment, patients do tend to relapse.6 MCL comprises about 3-6% of non-Hodgkin lymphomas, with an annual incidence of 0.5 per 100,000 population in Western countries; in the US, it is estimated that approximately 4,000 new patients are diagnosed with MCL each year.6,7

ECHO
ECHO is a randomised, double-blind, placebo-controlled, multi-centre Phase III trial evaluating the efficacy and safety of Calquence plus bendamustine and rituximab compared to SoC chemoimmunotherapy (bendamustine and rituximab) in adult patients at or over 65 years of age (n=635) with previously untreated MCL.8 Patients were randomised 1:1 to receive either Calquence or placebo administered orally twice per day, continuously, until disease progression or unacceptable toxicity. Additionally, all patients received six 28-day cycles of bendamustine on days 1 and 2 and rituximab on day 1 of each cycle, followed by rituximab maintenance for two years if patients achieved a response after induction therapy.8

The primary endpoint is PFS assessed by an Independent Review Committee; other efficacy endpoints include OS, overall response rate (ORR), duration of response (DoR) and time to response (TTR).8 The trial was conducted in 27 countries across North and South America, Europe, Asia and Oceania.8

The ECHO trial enrolled patients from May 2017 to March 2023, continuing through the COVID-19 pandemic. Patients with blood cancer remain at a disproportionately high risk of severe outcomes from COVID-19, including hospitalisation and death compared to the general population.9

Calquence
Calquence (acalabrutinib) is a second-generation, selective inhibitor of Bruton’s tyrosine kinase (BTK). Calquence binds covalently to BTK, thereby inhibiting its activity.10 In B-cells, BTK signalling results in activation of pathways necessary for B-cell proliferation, trafficking, chemotaxis and adhesion.

Calquence has been used to treat more than 85,000 patients worldwide11 and is approved for the treatment of CLL and small lymphocytic lymphoma (SLL) in the US and Japan, approved for CLL in the EU and many other countries worldwide and approved in China for relapsed or refractory CLL and SLL. Calquence is also approved in the US, China and several other countries for the treatment of adult patients with MCL who have received at least one prior therapy. Calquence is not currently approved for the treatment of MCL in Japan or the EU.

As part of an extensive clinical development programme, Calquence is currently being evaluated as a single treatment and in combination with standard-of-care chemoimmunotherapy for patients with multiple B-cell blood cancers, including CLL, MCL, and diffuse large B-cell lymphoma.
