TEPYLUTE® (thiotepa) Injection for Intravenous Use INDICATION TEPYLUTE is an alkylating drug indicated for the treatment of adenocarcinoma of the breast or ovary. IMPORTANT SAFETY INFORMATION WARNING: SEVERE MYELOSUPPRESSION and CARCINOGENICITY • TEPYLUTE may cause severe marrow suppression, and high doses may cause marrow ablation with resulting infection or bleeding. Monitor hematologic laboratory parameters. • TEPYLUTE should be considered potentially carcinogenic in humans. CONTRAINDICATIONS TEPYLUTE is contraindicated in patients with severe hypersensitivity to thiotepa and in concomitant use with live or attenuated vaccines. WARNINGS AND PRECAUTIONS Myelosuppression : For patients receiving TEPYLUTE for treatment of adenocarcinoma of the breast or adenocarcinoma of the ovary, if the bone marrow has been compromised by prior irradiation or chemotherapy, or is recovering from chemotherapy, the risk of severe myelosuppression with TEPYLUTE may be increased. Perform periodic complete blood counts during the course of treatment with TEPYLUTE. Provide supportive care for infections, bleeding, and symptomatic anemia. Inform patients of the possibility of developing low blood cell counts and the need for hematopoietic progenitor cell infusion. Instruct patients to immediately report to their healthcare provider if bleeding or fever occurs. Hypersensitivity: Clinically significant hypersensitivity reactions, including anaphylaxis, have occurred following administration of thiotepa. If anaphylactic or other clinically significant allergic reaction occurs, discontinue treatment with TEPYLUTE, initiate appropriate therapy, and monitor until signs and symptoms resolve. Counsel patients on the signs and symptoms of hypersensitivity and to seek immediate emergency assistance if they develop any of these signs and symptoms. Cutaneous Toxicity: TEPYLUTE and/or its active metabolites may be excreted in part via skin in patients receiving high-dose therapy. Treatment with TEPYLUTE may cause skin discoloration, pruritus, blistering, desquamation, and peeling that may be more severe in the groin, axillae, skin folds, in the neck area, and under dressings. Instruct patients to shower or bathe with water at least twice daily through 48 hours after administration of TEPYLUTE. Change the occlusive dressing and clean the covered skin at least twice daily through 48 hours after administration of TEPYLUTE. Change bed sheets daily during treatment. Skin reactions associated with accidental exposure to TEPYLUTE may occur. Wash the skin thoroughly with soap and water in case the TEPYLUTE solution contacts the skin. Flush mucous membranes in case of TEPYLUTE contact with mucous membranes. Concomitant Use of Live and Attenuated Vaccines: Do not administer live or attenuated viral or bacterial vaccines to a patient treated with TEPYLUTE until the immunosuppressive effects have resolved. Hepatic Veno-Occlusive Disease: Monitor by physical examination, serum transaminases, and bilirubin, and provide supportive care to patients who develop hepatic veno-occlusive disease. Central Nervous System Toxicity: Fatal encephalopathy has occurred in patients treated with high doses of thiotepa. Other central nervous system toxicities, such as headache, apathy, psychomotor retardation, disorientation, confusion, amnesia, hallucinations, drowsiness, somnolence, seizures, coma, inappropriate behavior, and forgetfulness have been reported to occur in a dose-dependent manner during or shortly after administration of high-dose thiotepa. Do not exceed the recommended dose of TEPYLUTE. If severe or life-threatening central nervous system toxicity occurs, discontinue administration of TEPYLUTE and provide supportive care. Carcinogenicity: Like many alkylating agents, thiotepa has been reported to be carcinogenic when administered to laboratory animals. Carcinogenicity is shown most clearly in studies using mice, but there is some evidence of carcinogenicity in man. There is an increased risk of secondary malignancy with the use of TEPYLUTE. Inform patients that TEPYLUTE can increase the risk of secondary malignancy. Polyethylene glycol (PEG) 400 toxicity : TEPYLUTE contains a high concentration of PEG 400. Based on findings in animals, administration of high amounts of PEG 400 may cause damage to the kidneys and liver at dosages higher than recommended. When prescribing TEPYLUTE, take into consideration the PEG 400 load from concomitant medications. Embryo-Fetal Toxicity: Based on the mechanism of action and findings in animals, TEPYLUTE can cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies of TEPYLUTE in pregnant women. Thiotepa given by the intraperitoneal (IP) route was teratogenic in mice at doses ≥1 mg/kg (3.2 mg/m 2 ), approximately 8-fold less than the maximum recommended human therapeutic dose (0.8 mg/kg, 27 mg/m 2 ), based on body-surface area. Thiotepa given by the IP route was teratogenic in rats at doses ≥3 mg/kg (21 mg/m 2 ), approximately equal to the maximum recommended human therapeutic dose, based on body-surface area. Thiotepa was lethal to rabbit fetuses at a dose of 3 mg/kg (41 mg/m 2 ), approximately two times the maximum recommended human therapeutic dose based on body-surface area. Advise pregnant women and females of reproductive potential of the potential risk to the fetus. Advise females of reproductive potential to use highly effective contraception during TEPYLUTE treatment and for 6 months after therapy/the last dose. Advise females of reproductive potential to inform their healthcare provider if they are pregnant or become pregnant. Advise males with female partners of reproductive potential to use effective contraception during TEPYLUTE treatment and for 1 year after therapy/the last dose. ADVERSE REACTIONS The most common adverse reactions (incidence greater than 10%) are neutropenia, anemia, thrombocytopenia, elevated alanine aminotransferase, elevated aspartate aminotransferase (AST), elevated bilirubin, mucositis, cytomegalovirus infection, hemorrhage, diarrhea, hematuria, and rash. The clinically significant adverse reactions include myelosuppression, infection, hypersensitivity, cutaneous toxicity, hepatic veno-occlusive disease, central nervous system toxicity, and carcinogenicity. DRUG INTERACTIONS Effect of Cytochrome CYP3A Inhibitors and Inducers: In vitro studies suggest that thiotepa is metabolized by CYP3A4 and CYP2B6 to its active metabolite triethylene phosphoramide (TEPA). Avoid coadministration of strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ritonavir) and strong CYP3A4 inducers (e.g., rifampin, phenytoin) with thiotepa due to the potential effects on efficacy and toxicity. Consider alternative medications with no or minimal potential to inhibit or induce CYP3A4. If concomitant use of strong CYP3A4 modulators cannot be avoided, closely monitor for adverse drug reactions. Effect of TEPYLUTE on Cytochrome CYP2B6 Substrates: In vitro studies suggest that thiotepa inhibits CYP2B6. Thiotepa may increase the exposure of drugs that are substrates of CYP2B6 in patients; however, the clinical relevance of this in vitro interaction is unknown. The administration of thiotepa with cyclophosphamide in patients reduces the conversion of cyclophosphamide to the active metabolite, 4‑hydroxycyclophosphamide; the effect appears sequence-dependent with a greater reduction in the conversion to 4-hydroxycyclophosphamide when thiotepa is administered 1.5 hours before the intravenous administration of cyclophosphamide compared to administration of thiotepa after intravenous cyclophosphamide. The reduction in 4-hydroxycyclophosphamide levels may potentially reduce the efficacy of cyclophosphamide treatment. USE IN SPECIFIC POPULATIONS Pregnancy: TEPYLUTE can cause fetal harm when administered to a pregnant woman based on findings from animals and the drug’s mechanism of action. Limited available data on thiotepa use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. In animal reproduction studies, administration of thiotepa to pregnant mice and rats during organogenesis produced teratogenic effects (neural tube defects and malformations of the skeletal system of the fetus) at doses approximately 0.125 and 1 times, respectively, the maximum recommended human daily dose on a mg/m2 basis. Thiotepa was lethal to rabbit fetuses at approximately 2 times the maximum recommended human therapeutic dose based on body-surface area. Consider the benefits and risks of TEPYLUTE for the mother and possible risks to the fetus when prescribing TEPYLUTE to a pregnant woman. Lactation: There is no information regarding the presence of thiotepa in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions, including the potential for tumorigenicity shown for thiotepa in animal studies, advise patients not to breastfeed during TEPYLUTE treatment and for 1 week after therapy/the last dose. Females and Males of Reproductive Potential: TEPYLUTE can cause fetal harm when administered to a pregnant woman. Pregnancy Testing - Verify the pregnancy status of females of reproductive potential before initiating TEPYLUTE therapy. Contraception for Females - Advise females of reproductive potential to avoid pregnancy during TEPYLUTE treatment and for 6 months after therapy/the last dose. Advise females to immediately report pregnancy. Contraception for Males - TEPYLUTE may damage spermatozoa and testicular tissue, resulting in possible genetic abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during TEPYLUTE treatment and for 1 year after therapy/the last dose. Infertility - Based on nonclinical findings, male and female fertility may be compromised by treatment with TEPYLUTE. Advise patients that TEPYLUTE can produce infertility. Inform male patients about the possibility of sperm conservation before the start of therapy. Pediatric Use: Safety and effectiveness of TEPYLUTE in neonates have not been established. Safety and effectiveness of TEPYLUTE for the treatment of adenocarcinoma of the breast and adenocarcinoma of the ovary in pediatric patients have not been established. Geriatric Use: Clinical studies of thiotepa for treatment of adenocarcinoma of the breast and adenocarcinoma of the ovary did not include sufficient numbers of subjects aged 65 years and over to determine whether elderly subjects respond differently from younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreasing hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Renal Impairment: In patients with moderate (creatinine clearance [CLcr] of 30 mL/min to 59 mL/min) renal impairment, decreased renal excretion may result in increased plasma levels of thiotepa and TEPA. This may result in increased toxicity. Monitor patients with moderate to severe (CLcr <30 mL/min) renal impairment for signs and symptoms of toxicity following treatment with TEPYLUTE for an extended period of time. Hepatic Impairment: Thiotepa is extensively metabolized in the liver. Patients with moderate (bilirubin levels greater than 1.5 times to 3 times the upper limit of normal and any AST) hepatic impairment may have increased plasma levels of thiotepa. This may result in toxicity. Monitor patients with moderate to severe (bilirubin levels greater than 3 times the upper limit of normal and any AST) hepatic impairment for signs and symptoms of toxicity following treatment with TEPYLUTE for an extended period of time.

- Label includes full spectrum of PKU patients - - European launch preparations underway - WARREN, N.J., April 25, 2025 /PRNewswire/ -- PTC Therapeutics, Inc. (NASDAQ: PTCT) announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion on the marketing authorization application for Sephience™ (sepiapterin) for the treatment of children and adults living with phenylketonuria (PKU). The opinion includes a broad label inclusive of all ages and disease severities. "This positive opinion is great news for the PKU patient community in Europe for whom there remains a significant unmet medical need," said Matthew B. Klein, M.D., Chief Executive Officer of PTC Therapeutics. "We look forward to initiating the European launch immediately following the adoption of this positive opinion by the European Commission. The data collected to date continue to support the potential for Sephience to provide a safe and effective treatment that not only lowers phenylalanine levels but also enables diet liberalization even for those with the most severe disease subtypes." Launch planning in Europe is well underway with priorities in Germany and other key European markets where named patient access will be immediately available. PTC expects the European Commission to ratify the marketing authorization for Sephience in approximately two months. The decision will be applicable to all 27 European Union member states, as well as Iceland, Norway and Liechtenstein. The New Drug Application (NDA) for sepiapterin is under review by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act (PDUFA) target action date of July 29, 2025. Review of approval applications is ongoing in several other countries including Japan and Brazil. About Sephience™ (sepiapterin) Sephience, an oral formulation of synthetic sepiapterin, has a dual mechanism of action to increase activity of the phenylalanine hydroxylase (PAH) enzyme. First, Sephience is a precursor compound that is rapidly absorbed and converted intracellularly to tetrahydrobiopterin (BH4), a critical cofactor of PAH. Sephience also has an independent pharmacological chaperone effect, correcting PAH misfolding to enhance the enzyme function. Through this dual mechanism of action, Sephience effectively reduces blood phenylalanine (Phe) levels and has the potential to treat a broad range of PKU patients. About Phenylketonuria Phenylketonuria (PKU) is a rare, inherited metabolic disease, which affects the brain. It is caused by a defect in the gene that helps create the enzyme needed to break down phenylalanine (Phe). If left untreated or poorly managed, Phe – an essential amino acid found in all proteins and most foods – can build up to harmful levels in the body. This causes severe and irreversible disabilities, such as permanent intellectual disability, seizures, delayed development, memory loss, and behavioral and emotional problems. Newborns with PKU initially don't have any symptoms, but symptoms are usually progressive, and damage caused by toxic levels of Phe in the first few years of life is irreversible. Diagnosis of PKU usually takes place during newborn screening programs. There are an estimated 58,000 people living with PKU globally. About PTC Therapeutics, Inc. PTC is a global biopharmaceutical company that discovers, develops and commercializes clinically differentiated medicines that provide benefits to children and adults living with rare disorders. PTC's ability to innovate new therapies and to globally commercialize products is the foundation that drives investment in a robust and diversified pipeline of transformative medicines.

Oryzon’s team is composed of highly qualified professionals from the pharma industry located in Barcelona, Boston, and San Diego. Oryzon has an advanced clinical portfolio with two LSD1 inhibitors, vafidemstat in CNS (Phase III-ready) and iadademstat in oncology (Phase II). The company has other pipeline assets directed against other epigenetic targets like HDAC-6 where a clinical candidate ORY-4001, has been nominated for its possible development in CMT and ALS. In addition, Oryzon has a strong platform for biomarker identification and target validation for a variety of malignant and neurological diseases. For more information, visit www.oryzon.com About IadademstatIadademstat (ORY-1001) is a small oral molecule, which acts as a highly selective inhibitor of the epigenetic enzyme LSD1 and has a powerful differentiating effect in hematologic cancers (see Maes et al., Cancer Cell 2018 Mar 12; 33 (3): 495-511.e12.doi: 10.1016 / j.ccell.2018.02.002.). A FiM Phase I/IIa clinical trial with iadademstat in R/R AML patients demonstrated the safety and good tolerability of the drug and preliminary signs of antileukemic activity, including a CRi (see Salamero et al, J Clin Oncol, 2020, 38(36): 4260-4273. doi: 10.1200/JCO.19.03250). Iadademstat has shown encouraging safety and strong clinical activity in combination with azacitidine in a Phase IIa trial in elder 1L AML patients (ALICE trial) (see Salamero et al., ASH 2022 oral presentation & The Lancet Haematology, 2024, 11(7):e487-e498). Iadademstat is currently being evaluated in combination with gilteritinib in the ongoing Phase Ib FRIDA trial in patients with relapsed/refractory AML with FLT3 mutations, and in combination with azacitidine and venetoclax in 1L AML in an investigator-initiated study led by OHSU and in a trial sponsored by the U.S. National Cancer Institute (NCI) under the Cooperative Research and Development Agreement (CRADA) signed between Oryzon and the NCI to collaborate on further clinical development of iadademstat in different types of hematologic and solid cancers. Beyond hematological cancers, the inhibition of LSD1 has been proposed as a valid therapeutic approach in some solid tumors such as small cell lung cancer (SCLC), neuroendocrine tumors (NET), medulloblastoma and others. In a Phase IIa trial in combination with platinum/etoposide in second line ED-SCLC patients (CLEPSIDRA trial), preliminary activity and safety results have been reported (see Navarro et al., ESMO 2018 poster). Iadademstat is in a collaborative Phase II trial with the Fox Chase Cancer Center (FCCC) in combination with paclitaxel in R/R neuroendocrine carcinomas, and in a Phase I/II randomized trial in 1L ED-SCLC in combination with ICI sponsored by NCI and led by the Memorial Sloan Kettering Cancer Center. Oryzon is further expanding the clinical development of iadademstat through additional investigator-initiated studies. Iadademstat has orphan drug designation for SCLC in the US and for AML in the US and EU. About Vafidemstat Vafidemstat (ORY-2001) is an oral, CNS-optimized LSD1 inhibitor. The molecule acts on several levels: it reduces cognitive impairment, including memory loss and neuroinflammation, and at the same time has neuroprotective effects. In animal studies vafidemstat not only restores memory but reduces the exacerbated aggressiveness of SAMP8 mice, a model for accelerated aging and Alzheimer’s disease (AD), to normal levels and also reduces social avoidance and enhances sociability in murine models. In addition, vafidemstat exhibits fast, strong, and durable efficacy in several preclinical models of multiple sclerosis (MS). Oryzon has performed two Phase IIa clinical trials in aggressiveness in patients with different psychiatric disorders (REIMAGINE, see Ferrer et al, Psychiatry & Clin Neurosci, 2025, doi.org/10.1111/pcn.13800) and in aggressive/agitated patients with moderate or severe AD (REIMAGINE-AD), with positive clinical results reported in both. Additional finalized Phase IIa clinical trials with vafidemstat include the ETHERAL trial in patients with Mild to Moderate AD, where a significant reduction of the inflammatory biomarker YKL40 was observed after 6 and 12 months of treatment, and the pilot, small-scale SATEEN trial in Relapse-Remitting and Secondary Progressive MS, where anti-inflammatory activity was also observed. Vafidemstat has also been tested in a Phase II in severe Covid-19 patients (ESCAPE) assessing the capability of the drug to prevent ARDS, one of the most severe complications of the viral infection, where it showed significant anti-inflammatory effects in severe Covid-19 patients. Vafidemstat is currently advancing as a Phase III-ready asset in Borderline Personality disorder (BPD) following completion of the global, randomized, double blind Phase IIb PORTICO trial (final data presented at ECNP-2024). Following receipt of the minutes from the End-of-Phase II meeting with the FDA to discuss PORTICO’s results, the company announced plans to move forward with a Phase III PORTICO-2 trial in agitation/aggression in BPD (FDA submission planned in 1H2025). Vafidemstat is also being investigated in a double-blind, randomized, placebo-controlled Phase IIb trial in negative symptoms of schizophrenia (EVOLUTION trial, recruitment ongoing). The company is also deploying a CNS precision medicine approach with vafidemstat in genetically-defined patient subpopulations of certain CNS disorders and is evaluating a clinical trial in Kabuki Syndrome patients. The company is also exploring the clinical development of vafidemstat in other neurodevelopmental syndromes.
