NANJING, China and GAITHURSBURG, Md., March 8, 2024 /PRNewswire/ -- TransThera, a clinical-stage biopharmaceutical company dedicated to innovating differentiated drugs globally, today announced that the randomized, controlled, global multicenter Phase 3 trial (FIRST-308) of tinengotinib versus physician's choice to evaluate the efficacy and safety in subjects with FGFR-altered, chemotherapy- and FGFR Inhibitor-refractory/relapsed cholangiocarcinoma (CCA), has been authorized by regulatory agencies in the European Union (EU) after the authorizations from US, South Korea and Taiwan region. Furthermore, European Medicines Agency (EMA) granted the Orphan Drug Designation(ODD) for tinengotinib for the treatment of biliary tract cancer (BTC) . Tinengotinib, a next-generation FGFR inhibitor with high potency against a variety of FGFR2 kinase domain mutations, has shown promising clinical benefit in subjects with FGFR-altered metastatic CCA who were heavily pretreated with chemotherapy and refractory/relapsed to FGFRi(s). The results of tinengotinib in CCA from the phase I/II clinical trials were presented orally at 2023 ESMO and 2024 ASCO GI conferences. The FRIST-308 clinical trial is enrolling to further confirm the efficacy and safety of tinengotinib in CCA. In December 2023, first patient was dosed in the United Sates (US). "We are very delighted to have achieved the significant regulatory progresses for tinengotinib in global development at various countries and regions. These milestones are not only the recognition by global regulatory authorities of the potential clinical benefit of tinengotinib to treat CCA patients, but also a reflection of the company's international regulatory capabilities and unwavering commitment to bringing innovative therapies to global patients," said Jean Fan, M.D., Chief Medical Officer of TransThera Sciences. "Leveraging the regulatory agency's support from the EU in addition to the US and other countries and regions, we will continue to expedite the global clinical development and commercialization of tinengotinib. We are hopeful that these efforts will enable us to bring this novel drug to patients around the world as quickly as we can." About ODD in EU The term "orphan medicines" refers to pharmaceutical products developed for the prevention, diagnosis, and treatment of rare diseases or conditions affecting less than 5 in 10,000 people in the EU. The EMA offers a range of incentives to encourage the development of designated orphan medicines. This Orphan Drug Designation for tinengotinib qualifies it for great regulatory supports in the subsequent clinical development and commercialization in the EU, including protocol assistance, fee reductions, and most importantly, 10 years of market exclusivity upon approval. About tinengotinib Tinengotinib is an innovative, global phase III stage spectrum-selective kinase inhibitor that exerts antitumor effects by targeting tumor cells proliferation, angiogenesis and immune-oncology pathways by inhibiting the cytokine signaling and angiogenesis (FGFRs and VEGFRs), mitotic kinases Aurora A/B and Janus kinases (JAK). Ongoing clinical trials in the US and China have revealed the potential of tinengotinib to be efficacious in various solid tumors. It was granted the Orphan Drug Designation and Fast Track Designation by the FDA for the treatment of CCA. In July 2023, tinengotinib was granted the Breakthrough Therapy Designation (BTD) by NMPA in China. In March 2024, tinengotinib was granted the Orphan Drug Designation(ODD) for the treatment of biliary tract cancer by EMA.

Net income attributable to HUTCHMED of $100.8 million.2024 Oncology/Immunology consolidated revenue guidance of $300 million to $400 million, driven by 30% to 50% growth target in marketed product sales and royalties.R&D expenses focused in line with strategy targeting key projects.Strengthened cash balance, with $886.3 million at year end (2022: $631.0m), ensures HUTCHMED is well placed to deliver on its objective of becoming a self-sustaining business. 2023 FULL YEAR RESULTS & BUSINESS UPDATES Mr Simon To, Executive Chairman of HUTCHMED, said, “We have made significant progress throughout 2023. We executed against our commitment to bring our innovative medicines to patients worldwide with the U.S. FDA approval of FRUZAQLA™ in November 2023, while remaining dedicated to becoming a self-sustaining business. The Takeda partnership, which is one of the biggest small-molecule overseas licensing deals in the history of China biotech, strengthened our cash position by $435 million. Takeda delivered a successful U.S. launch within 48 hours of approval, and has subsequently seen strong early patient uptake.” “We will continue to deliver on our strategy in 2024. We will stay focused on our target of becoming sustainable through our balanced strategy of growing sales of our novel medicines in China, and advancing our medicines overseas with our partners. This, when combined with our other goals on pipeline progression and further business development, means that while the global macroeconomic environment remains uncertain, HUTCHMED is positioned to thrive and continue to deliver innovative medicines to ever more patients around the world.” Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said, “HUTCHMED delivered impressive financial results in 2023, with revenue up 97% to $838 million. This, alongside our significantly strengthened cash balance of $886 million, will enable us to continue advancing our pipeline and successfully executing our strategy.” “2023 was an important year for HUTCHMED, particularly for fruquintinib, for which we filed market authorization applications in the U.S., EU and Japan, based on the successful FRESCO-2 study. Following the U.S. FDA approval for third-line patients with advanced CRC, we continue to work together with Takeda to pursue additional launches in new markets worldwide. In China, we also filed an NDA for second-line gastric cancer based on the FRUTIGA study.” “Another milestone was the successful ESLIM-01 registration study in China in ITP patients for sovleplenib, our first potential novel medicine in immunological diseases. The NDA was accepted and granted priority review by the NMPA in January 2024. There are over 250,000 new and existing adult ITP patients in China20. The treatment options are limited to steroids and TPO/TPO-RAs21, representing an unmet medical need that sovleplenib could help address, with its new mechanism of action and favorable safety profile. Syk inhibition has the potential to target other major diseases such as rheumatoid arthritis. We are also planning to initiate clinical development of sovleplenib outside China in 2024.” “For savolitinib, we completed the confirmatory trial in NSCLC patients with MET22 exon 14 skipping alterations. An NDA submission is expected in the first quarter of 2024, with potential to expand the label indication to include first-line patients in China. Outside China, we will continue our work with AstraZeneca on the pivotal global savolitinib lung cancer trial SAVANNAH, which, subject to favorable data, can support a filing to the U.S. FDA for approval. This study completed enrollment with a potential NDA submission towards the end of 2024 in EGFR23 mutant NSCLC patients who progressed on TAGRISSO® treatment, which received U.S. FDA Fast Track designation in January 2023. We believe the convenient dosing, targeted efficacy and safety profile of savolitinib as an oral medicine in combination with TAGRISSO®, the leading oral third-generation EGFR TKI24, should position it well in a competitive market and address the unmet needs of MET+ NSCLC patients.” "Our China commercialization efforts progressed well, as we successfully renewed NRDL25 coverage for both fruquintinib and surufatinib without further price reduction. Their in-market sales saw strong growth in 2023. Over the next two years, we plan to continue growth in China through expanded indications and the launch of new products together with revenue from FRUZAQLA™ overseas commercialization.” I.

(Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, today provided a business update and reported financial results for the fourth quarter and full year of 2023. “We have entered 2024 in a very strong position,” said Andrew Robbins, Cogent’s President and Chief Executive Officer. “We are now actively enrolling three registration-directed clinical trials of bezuclastinib across NonAdvSM, AdvSM and 2nd-line GIST patients, all of which are on track to deliver top-line results in 2025. With our recent fundraising, we are funded into 2027, and based on the clinical data we have presented across these programs to date, believe strongly that bezuclastinib has the opportunity to become the best-in-class KIT mutant inhibitor for these three indications.” Q4 2023 and Recent Business Highlights In February 2024, reported positive Part 1b data from the Company’s ongoing Phase 2 SUMMIT trial at the 2024 American Academy of Allergy Asthma & Immunology Annual Meeting (AAAAI) meeting. SUMMIT is a registration-directed, randomized, double-blind, placebo-controlled, global, multicenter, clinical trial of bezuclastinib in patients with nonadvanced systemic mastocytosis (NonAdvSM). Key highlights include: Announced the 100 mg Recommended Phase 2 Dose (RP2D)Demonstrated a well-tolerated safety profile, generally consistent with placeboIntroduced Cogent’s MS2D2, a novel, refined patient reported outcomes measure (PROM) designed to assess symptomatic severity and improvementReported a 51% week 12 mean improvement in total symptom score (TSS) for bezuclastinib, including 70% of patients achieving ≥50% improvement in symptom severityReported a 49% week 12 mean improvement in quality of life (MC-QoL) for bezuclastinib In February 2024, closed a $225 million oversubscribed private investment in public equity (PIPE) financing. Cogent sold approximately 17 million shares of its common stock at a price of $7.50 per share, representing a premium of approximately 37% to its closing price on February 13, 2024. The financing also included Series B non-voting convertible Preferred Stock convertible into approximately 13 million shares of its common stock.In December 2023, reported positive clinical data from the Phase 2 SUMMIT and APEX trials at the American Society of Hematology (ASH) annual meeting. Highlights from APEX, a registration-directed trial evaluating bezuclastinib in patients with advanced systemic mastocytosis (AdvSM), include: Reported an encouraging safety and tolerability profile with no related cognitive impairment or bleeding eventsAchieved impressive effects in key biomarkers of disease burdenAchieved 56% Overall Response Rate (ORR) in TKI-naïve patients, including 86% ORR by Pure Pathological Response (PPR) criteria In December 2023, presented new preclinical data highlighting the potential best-in-class potency and selectivity of Cogent’s ErbB2 inhibitor and announced a third Cogent discovery stage PI3Kα inhibitor program at the San Antonio Breast Cancer Symposium (SABCS). The novel EGFR-sparing, brain-penetrant ErbB2 inhibitor demonstrated a superior efficacy profile, reaching 80% brain penetrance with potent coverage of key mutationsThe novel, H1047R mutant-selective PI3Kα inhibitor demonstrated high clinical target engagement without metabolic dysfunction commonly associated with molecules in the class In November 2023, reported updated clinical data from the lead-in portion of the ongoing PEAK Phase 3 trial evaluating bezuclastinib in combination with sunitinib in patients with GIST at the Connective Tissue Oncology Society (CTOS) annual meeting. Positive lead-in data was first presented at the 2023 American Society of Clinical Oncology (ASCO) annual meeting in June. Safety and tolerability data from 42 patients enrolled in Part 1a and Part 1b were consistent with results shared at the 2023 ASCO annual meeting, demonstrating the combination of bezuclastinib and sunitinib was well tolerated with an adverse event profile similar to sunitinib monotherapyUpdated clinical activity from a subset of 2nd-line GIST patients demonstrated a 33% confirmed overall response rate (ORR) with ongoing median duration of therapy greater than 14 months. Together with clinical data previously reported from a Phase 1/2 trial, 4 of 10 evaluable 2nd-line GIST patients treated with the combination have reached confirmed partial response status In October 2023, presented updated preclinical data from the Company’s next-generation selective fibroblast growth factor receptor 2 (FGFR2) program in a poster presentation at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. The poster showed Cogent’s internally-developed FGFR2 inhibitor exhibits low nM potency on WT FGFR2 and FGFR2 mutations and is selective against the kinome and a panel of channels and receptors.Exploratory pharmacokinetics (PK) studies conducted across species showed CGT4859 to be a low-clearance compound with high oral bioavailability. Further, in an AN3 CA model, CGT4859 demonstrated dose-responsive tumor growth inhibition with complete regressions at 5 mg/kg PO and was well-tolerated Projected Near-Term Milestones Bezuclastinib – Systemic Mastocytosis (SM) Complete enrollment in SUMMIT Part 2 in the second quarter of 2025 and deliver top-line results by the end of 2025 Provide additional safety, tolerability and patient-reported outcomes data from the open label extension portion of SUMMIT Part 1 during 2024Complete enrollment in the registration-directed APEX Phase 2 trial in patients with Advanced Systemic Mastocytosis (AdvSM) by the end of 2024 Bezuclastinib – Gastrointestinal Stromal Tumors (GIST) Complete enrollment in the global, randomized Phase 3 PEAK trial in 2nd-line GIST patients by the end of 2024Provide additional clinical results from the PEAK lead-in trial, including longer duration safety and tolerability results along with updated efficacy measures, including objective response rate (ORR) and progression free survival (PFS) during 2024 CGT4859 (FGFR2 inhibitor) Initiate a Phase 1 trial of the first Cogent-discovered pipeline program, designed as a potent, selective, reversible FGFR2 inhibitor with best-in-class potential in the second half of 2024 Preclinical Pipeline Initiate IND-enabling studies for lead candidate from potent, selective ErbB2 program, highlighted by potential best-in-class brain penetrant propertiesSelect lead candidate and initiate IND-enabling studies from ongoing PI3Ka program, designed to potently and selectively target the H1047R driver mutation, which affects >30,000 cancer patients each year Upcoming Investor Conference Leerink Healthcare Conference on Tuesday, March 12 at 2:20 p.m. ET. A live webcast can be accessed on the Investors & Media page of Cogent’s website at investors.cogentbio.com/events. A replay will be available approximately two hours after completion of the event and will be archived for up to 30 days. Fourth Quarter and Full Year 2023 Financial Results Cash and Cash Equivalents: As of December 31, 2023, Cogent had cash, cash equivalents and marketable securities of $273.2 million. Cogent believes this year-end balance, together with the gross proceeds from the $225.0 million oversubscribed private placement, which closed February 16, 2024, will be sufficient to fund its operating expenses and capital expenditure requirements into 2027, including through clinical readouts from the ongoing SUMMIT, PEAK and APEX registration-directed trials.
