Interim Results from FDA-Funded Study Reinforces HyBryte's ™ Rapid Response and Strong Safety ProfilePRINCETON, N.J., April 14, 2025 /PRNewswire/ -- Soligenix, Inc. (Nasdaq: SNGX) (Soligenix or the Company), a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need, announced today interim results from the ongoing open-label, investigator-initiated study (IIS) evaluating extended HyBryte™ (synthetic hypericin) treatment for up to 54 weeks in patients with early-stage cutaneous T-cell lymphoma (CTCL). Following 18 weeks of treatment, 75% of patients achieved "Treatment Success," reinforcing HyBryte™ as a potentially safe and fast-acting therapy for this chronic and underserved cancer. Continue Reading HyBryteTM (0.25%) hypericin (PRNewsfoto/SOLIGENIX, INC.) The IIS is sponsored by Ellen Kim, MD, Director, Penn Cutaneous Lymphoma Program, Vice Chair of Clinical Operations, Dermatology Department, and Professor of Dermatology at the Hospital of the University of Pennsylvania who was a leading enroller in the Phase 3 FLASH (Fluorescent Light Activated Synthetic Hypericin) study and is the Principal Investigator for the confirmatory Phase 3 FLASH 2 study for the treatment of early-stage CTCL. To date, nine patients have been enrolled and treated with HyBryte™ over a time period of up to 54 weeks in the IIS, with all data for the Week 18 timepoint now complete. Consistent with the Phase 3 trials, Treatment Success is predefined as a greater than or equal to 50% improvement in the cumulative mCAILS (modified Composite Assessment of Index Lesion Severity) score compared to Baseline. Of the eight patients who could be evaluated through Week 18, six (75%) had a Treatment Success. The 18-week treatment window is the same window that is being evaluated in the FLASH 2 double-blind, placebo-controlled, randomized study that is currently enrolling patients. This rapid response is a distinct advantage of HyBryte™ therapy, with many other therapies used in CTCL taking up to six to 12 months to generate a clinically meaningful treatment response. Of these eight evaluable patients through Week 18, four have gone on to complete the 54-week treatment with an average maximum improvement in mCAILS score of 85%, three are still on treatment and one dropped out (due to logistical issues). HyBryte™ appears to be safe and well tolerated in all patients. "The complete response rates observed, including three patients achieving a complete response on this study to date, as well as the consistent treatment response and safety profile across multiple HyBryte™ clinical studies, has been exciting to see," noted Dr. Kim, Principal Investigator of the IIS. "In the first Phase 3 FLASH study, HyBryte™ was shown to be efficacious with a benign safety profile compared to the current therapies of steroids, chemotherapeutics and ultraviolet light in this chronic orphan disease. With limited treatment options, especially in the early stages of their disease, CTCL patients are often searching for alternative treatments. In our study funded by the U.S. Food and Drug Administration (FDA), initial results evaluating the expanded use of HyBryte™ in a "real world" treatment setting remain very promising, further supporting and extending results from the previous positive Phase 2 and 3 clinical trials. It also provides further confidence to the potential responses we can expect to see in the confirmatory Phase 3 placebo-controlled FLASH 2 study. We look forward to continuing to work with the FDA to complete the IIS while we participate in the confirmatory 18-week FLASH 2 study." "We are pleased with these recent study results, giving patients an opportunity to access the therapy in an open-label setting," stated Christopher J. Schaber, PhD, President and Chief Executive Officer of Soligenix. "CTCL is an incredibly difficult to treat orphan disease and remains an area of unmet medical need with a very limited number of safe and effective therapies. Following the initial Phase 3 FLASH study, which demonstrated the safety and efficacy of shorter courses of HyBryte™ therapy, we are pleased to see that continuing treatment for longer time periods is resulting in the anticipated improved outcomes for patients. The majority of patients show a strong treatment response by Week 18, a noticeable advantage over other therapies that may take six to 12 months to show improvement. As the body of compelling data continues to grow in support of this novel therapy, we look forward to continuing to work with Dr. Kim on this important study as well as advancing enrollment in the 80-patient confirmatory Phase 3 FLASH 2 replication study. We will plan to provide additional updates on the IIS as data becomes available."The clinical study RW-HPN-MF-01, "Assessment of Treatment with Visible Light Activated Synthetic Hypericin Ointment in Mycosis Fungoides Patients" is designed as an open-label, multicenter clinical trial enrolling approximately 20 patients in the U.S. Patients have the potential to be treated for up to 54 weeks with twice a week dosing (visible light activation following ointment application by 24 ± 6 hours). The study also allows for potential transition to a "real-world" setting with home-use. The primary endpoint for the study is evaluating the number of treatment successes defined as ≥50% reduction in the cumulative mCAILS score from Baseline to end of the treatment. Study RW-HPN-MF-01 is supported by an FDA Orphan Products Development Grant of up to $2.6 million. 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 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 FLASH 2, 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 FLASH 2 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.Additional supportive studies have demonstrated the utility of longer treatment times (Study RW-HPN-MF-01, see above), 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).In addition, the FDA awarded an Orphan Products Development grant to support the investigator-initiated study 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. 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 U.S. 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).

Gelclair® is the company's third commercialized prescription product Oral mucositis, also called "chemo mouth," a painful inflammation of the mouth's mucous membranes, has emerged as the most significant adverse event in oncology according to a National Comprehensive Cancer Network task force Napo's core target patient audiences for Gelclair are head and neck cancer patients and bone marrow transplant patients SAN FRANCISCO, CA / ACCESS Newswire / April 8, 2025 / Jaguar Health, Inc. (NASDAQ:JAGX) ("Jaguar") today announced that Jaguar family company Napo Pharmaceuticals ("Napo") is exhibiting at the 50th anniversary Oncology Nursing Society (ONS) Congress taking place April 9-13, 2025 in Denver, Colorado as part of ongoing commercial activities for Gelclair. "We have expanded our footprint beyond HIV-related supportive care to include cancer-related supportive care, and our recent in-licensing of the FDA-approved oral mucositis product Gelclair is a first building block," said Lisa Conte , Jaguar's president and CEO. "Cancer is chaotic, because patients feel a loss of control - over their life, their treatment, and their supportive care needs," said Conte. "Jaguar's mission is to change patients' lives for the better, especially in the area of supportive care for complex disease states like cancer. We look forward to driving awareness among the oncology nursing community at ONS about Gelclair. Oral mucositis, also called "chemo mouth," is among the most common, painful, and debilitating cancer treatment-related side effects, and it is undertreated and underappreciated. We believe we can help cancer patients by giving them a supportive care product for oral mucositis that provides soothing, quick, and lasting pain relief without stinging, drying or burning." "If it weren't for Gelclair, I don't know if I would have continued with chemo. It was that painful. Gelclair gave me relief when nothing else did - it allowed me to keep going," said Megan-Claire, a Gelclair patient brand ambassador for Napo. Gelclair is a protective gel with a mechanical action indicated for the management of pain and relief of pain by adhering to the mucosal surface of the mouth, soothing oral lesions of various etiologies, including oral mucositis/stomatitis. Unlike other products for oral mucositis, it is not a numbing agent and does not sting the mouth. "Nurses play a vital role in providing integrated supportive care to cancer survivors to meet various physical, psychological, and social support needs," added Conte. "Jaguar and Napo acknowledge the rigors of both short-term and chronic treatment and do not believe any cancer therapy-related side effect, whether it is extreme fatigue, debilitating diarrhea, oral mucositis, hair loss, chronic pain, or others, should ever be viewed as ‘acceptable' or ‘tolerable.' We live in the age of targeted therapies, and thanks to these amazing drugs, cancer patients are living longer - 5, 10, 20 years. Targeted therapies often lead to more severe side effects, however, and patients want to live, not just survive." Napo's core target audiences for Gelclair are head and neck cancer patients and bone marrow transplant patients, and oncology-focused health care professionals. Head and neck cancers account for nearly 4 percent of all cancers in the United States , according to the National Cancer Institute (NCI).1 Counting cancers of the oral cavity, pharynx, and larynx, the NCI estimates that about 71,110 cases were diagnosed in the U.S. in 2024.2 Approximately another 23,000 patients each year undergo bone marrow transplant procedures. Oral mucositis has emerged as the most significant adverse event in oncology according to a National Comprehensive Cancer Network task force.3 Up to 40% of all patients treated with chemotherapy develop oral mucositis, and this percentage rises to approximately 90% for patients with head and neck cancers treated with chemotherapy and radiotherapy.4 Of the latter, 19% may end up being hospitalized, experiencing a delay in antineoplastic treatment for high-grade mucositis management, resulting in a reduction of the quality of life, a worse prognosis, and an increase in patient management costs.4 Oral mucositis impacts a patient's ability to swallow, speak, eat, and drink - and may lead to cancer treatment discontinuation.5 It is estimated that at least 11% of head and neck cancer patients experience cancer treatment interruption due to oral mucositis.6 "Those of us working in the oncology field know the impact that side effect-related delays or cessation of cancer treatment can have on overall survival and on the efficacy of treatment," Conte said. "Of patients with head and neck cancers treated with chemotherapy and radiotherapy who develop oral mucositis, half of the cases are typically considered severe - meaning oral mucositis of grade 3 or 4, which may require hospitalization and may require parenteral nutrition and IV hydration, and the morbidity and expense associated with those interventions." Jaguar also remains focused on development of crofelemer for cancer therapy-related diarrhea (CTD). As announced, the analysis of the prespecified subgroup of adult patients with breast cancer from Napo's recently conducted Phase 3 prophylactic OnTarget clinical trial for diarrhea in adult patients with solid tumors receiving targeted therapy with or without standard chemotherapy indicates that crofelemer achieved statistically significant results in this subgroup. These results were the subject of a December 11, 2024 poster presentation at the San Antonio Breast Cancer Symposium and the late-breaker abstract recently submitted to the Multinational Association of Supportive Care in Cancer (MASCC) for consideration for presentation at the June 2025 MASCC Annual Meeting. As also announced, the U.S. Food and Drug Administration (FDA) has granted Napo a Type C Meeting in the second quarter of 2025 to discuss the responder analysis in the prespecified subgroup of patients with breast cancer for crofelemer in OnTarget . The company's goal is to discuss the most efficient pathways to make crofelemer available to this patient population for CTD. The annual ONS Congress is a prominent event for professionals and organizations who are committed to the promotion of excellence in oncology nursing and the transformation of cancer care. ONS is a professional association that represents 100,000 nurses and is the professional home to more than 35,000 members. Since 1975, ONS has provided a professional community for oncology nurses, developed evidence-based education programs and treatment information, and advocated for patient care, all in an effort to improve the quality of life and outcomes for patients with cancer and their families.

Vigabatrin REMS All vigabatrin products are governed by a Risk Evaluation and Mitigation Strategy (REMS) mandated by the FDA. The Vigabatrin REMS ensures that patients and healthcare providers make informed risk-benefit decisions about its use. Healthcare providers must be enrolled in the Vigabatrin REMS to prescribe these products, and patients must be enrolled to receive them. WHAT IS VIGAFYDE? VIGAFYDE™ (vigabatrin) Oral Solution is a prescription medicine used to treat: Infantile Spasms (IS) in babies 1 month to 2 years of age, if you and your baby's healthcare provider decide the possible benefits of taking VIGAFYDE are more important than the possible risk of vision loss. WHAT IMPORTANT SAFETY INFORMATION SHOULD I KNOW ABOUT VIGAFYDE™ (vigabatrin)? Because VIGAFYDE might cause permanent vision loss, it is available to healthcare providers and patients only under a special program called the Vigabatrin Risk Evaluation and Mitigation Strategy (REMS) Program. Your baby's healthcare provider will explain the details of this Program to you. VIGAFYDE can damage the vision of anyone who takes it. Some people can have severe loss, particularly to their ability to see to the side when looking straight ahead (peripheral vision). With severe vision loss, your baby may only be able to see things straight in front of them (sometimes called "tunnel vision"). Your baby may also have blurry vision. If this happens, it will not get better. Tell your healthcare provider right away if your baby might not be seeing as well as before starting VIGAFYDE or is acting differently than normal. These changes can mean that vision damage has occurred. Regular vision testing is recommended. It is recommended that your healthcare provider test your baby's vision before or within 4 weeks after starting VIGAFYDE, and at least every 3 months during treatment until VIGAFYDE is stopped. It is also recommended that vision be tested about 3 to 6 months after VIGAFYDE is stopped. It is difficult to test vision in babies, but to the extent possible, all patients should have their vision tested. Your baby's healthcare provider will determine if testing can be done. Regular vision testing is important because damage can happen before any changes are noticed. Vision tests cannot prevent the vision damage that can happen with VIGAFYDE, but they do allow VIGAFYDE to be stopped if vision has gotten worse, which usually will lessen further damage. Even these regular vision tests may not show vision damage before it is serious and permanent. Parents, caregivers, and healthcare providers may not recognize the symptoms, or find vision loss in babies, until it is severe. If you do not have these vision tests regularly, your baby's healthcare provider may stop prescribing VIGAFYDE. Your baby may not be able to complete vision testing. If vision testing cannot be done, the healthcare provider may continue prescribing VIGAFYDE but will not be able to watch for any vision loss. Magnetic resonance imaging (MRI) changes in patients with infantile spasms (IS). Brain pictures taken by MRI show changes in some patients after they are given VIGAFYDE. It is not known if these changes are harmful. A type of swelling in the brain called intramyelinic edema (IME) has been seen in postmortem examination of infants treated with vigabatrin. Risk of suicidal thoughts or actions. VIGAFYDE is approved for use in patients 1 month to 2 years of age [see WHAT IS VIGAFYDE?]. VIGAFYDE is not approved for use in adolescents or adults. Like other antiepileptic drugs, vigabatrin may cause suicidal thoughts and actions in some adolescents and adults (about 1 in 500 people). A healthcare provider should be called right away if a patient taking vigabatrin experiences any symptoms, especially sudden changes in mood, behaviors, thoughts, or feelings, and especially if they are new, worse, or worrying. Do not stop VIGAFYDE without first talking to a healthcare provider. Stopping VIGAFYDE suddenly can cause seizures that will not stop. VIGAFYDE is more concentrated than vigabatrin solutions prepared from powder. The volume of VIGAFYDE solution prescribed by your baby's healthcare provider may be less than the volume prescribed for other vigabatrin solutions prepared from powder. Always double check the volume (mL) that you are to give your baby when you get a new prescription filled. VIGAFYDE can cause serious side effects such as low red blood cell counts (anemia), sleepiness and tiredness, and weight gain. VIGAFYDE may make certain types of seizures worse. Tell your healthcare provider right away if seizures get worse. Before starting VIGAFYDE, tell your baby's doctor about all of their medical conditions including any allergic reaction to vigabatrin, vision problems, kidney problems, or low red blood cell counts (anemia). Tell your doctor about all the medicines you baby is receiving. The most common side effects of VIGAFYDE in babies include: sleepiness (sleepy babies may have a harder time suckling and feeding or may be irritable), swelling in the bronchial tubes (bronchitis), ear infection and irritability. Tell your healthcare provider if your baby has any side effect that bothers them or that does not go away. This is the most important information to know about VIGAFYDE, but not all of the safety information. For more information, ask your healthcare provider or pharmacist, or please see the VIGAFYDE Medication Guide, full Prescribing Information including Boxed Warning for risk of permanent vision loss, and Instructions for Use.

WHAT IS VIGADRONE? VIGADRONE® (vigabatrin) is a prescription medicine used to treat: Infantile Spasms (IS) in patients 1 month to 2 years of age, if you and your healthcare provider decide the possible benefits of taking VIGADRONE are more important than the possible risk of vision loss.
