Hutchmed expanded its presence in blood cancers by developing a Menin inhibitor

 HUTCHMED (formerly Hutchison MediPharma) has introduced its Menin-MLL inhibitor HMPL-506 into a phase 1 trial, aiming to broaden its footprint in hematological malignancies. The company filed the IND application for HMPL-506 in January 2024 in China.  Menin binds to KMT2A, activating leukemogenic genes like HOX and MEIS1. However, when a Menin inhibitor binds to the pocket of menin and displaces KMT2A, it deactivates HOX and MEIS genes, halting the growth of leukemic cells. Targeting Menin Currently, HUTCHMED possesses several drug candidates targeting SYK, PI3Kδ, IDH1/2, BTK, CD47, and Menin, in addition to the in-licensed EZH2 inhibitor tazemetostat, all of which are part of the pipeline for blood cancers. HUTCHMED Pipeline in 2024Q1 HMPL-506 MLL gene rearrangements (MLL-r, also known as KMT2A) are found in 5%-10% of acute leukemias and are linked to a poorer prognosis. On the other hand, nucleophosmin 1 mutations (NPM1m) are the most frequent genetic changes seen in acute myeloid l

China CDE clears the IND application for WhiteOak/Haichang's HC0301/WGI-0301

 China's CDE has cleared the IND application for WGI-0301/HC0301, which is a lipid nanoparticle (LNP) formulation of an AKT-1 antisense oligonucleotide that binds to AKT-1 mRNA discovered by WhiteOak, a subsidiary of Haichang Biotech. This clearance is for use in patients with hepatocellular carcinoma. The product (RX-0301), along with WGI-0201/HC0201 (RX-0201) and WGI-0047 (RX-0047), was licensed from Rexahn Pharmaceuticals (now Ocuphire Pharma) in 2018. WGI-0301 X-0301 is a nano-liposomal formulation of RX-0201, an antisense oligonucleotide compound designed to enhance delivery to target mRNA encoding Akt-1. RX-0201 works by binding to the mRNA, thereby inhibiting its transcription and the subsequent production of Akt-1 protein.  RX-0201 Rexahn explored the clinical use of RX-0201 in patients with pancreatic cancer and renal cell cancer before 2018.  The median PFS in evaluable patients with mRCC treated with RX-0201 in combination with everolimus was 4.9 months, which is compar

Hemay seeks NMPA approval of mufemilast for plaque psoriasis

 China CDE has accepted for review a new drug application (NDA) seeking the approval of mufemilast, a PDE4 inhibitor developed by Hemay Pharma, for the treatment of plaque psoriasis. The NDA may be based on only one placebo-controlled randomized phase 3 trial, as the study was initiated before the approval of the standard therapy.  The first PDE4 inhibitor, apremilast, was approved in China in 2021, which is 7 years after its approval in the United States. PDE4 pathway Mufemilast Mufemilast (Hemay005) is an orally active selective PDE4 inhibitor ( in vitro IC50 = 80–120 nM ), which is under evaluation in patients with plaque psoriasis,  Behçet's disease, atopic dermatitis, ankylosing spondylitis, and ulcerative colitis. Hemay005 At ACR Convergence 2023, Hemay Pharma revealed the findings from clinical studies of mufemilast in patients with plaque psoriasis and Behçet's disease. In the phase 3 trial, mufemilast (60 mg BID) exhibited a PASI75 response of 53.6% compared to 16.0%

Lepu Biopharma and Miracogen brings MRG006A to IND stage

  Lepu Biopharma and Miracogen have submitted the IND application for MRG006A, an anti-GPC3 ( Glypican-3 ) ADC in China, and the IND application is also expected to be submitted to the US FDA this year. MRG006A MRG006A is a GPC3-targeting ADC composed of a novel humanized IgG1 antibody conjugated to a potent topoisomerase 1 inhibitor via a peptide-based cleavable linker, with a DAR ratio of 8. MRG006A Lepu Biopharma and  Miracogen presented the results of the preclinical study of MRG006A at the 2023 AACR Annual Meeting. Highlights demonstrated its superior binding activity to GPC3-expressing cancer cell lines, rapid internalization, and potent GPC3-dependent cytotoxic activity. In 2022, Miracogen filed a patent (WO2024061305 ) covering the GPC3 ADCs and their use in cancers, including liver cancer.  The ADCs discussed in the examples included several candidates with DAR values ranging from 2 to 4, all of which were tested in the LIV#219 liver cancer PDX model. GPC3 targeting ADCs C

Simcere has advanced SIM0500 (GPRC5D×BCMA×CD3) to the phase 1 study

 Simcere and its subsidiary Xianxiang have initiated the phase 1 study ( NCT06375044 ) of SIM0500, an anti-GPRC5D×BCMA×CD3 tri-specific antibody  in China. The first-in-human trial is estimated to enroll 130 patients  to evaluate the safety, tolerability, efficacy, and pharmacokinetics of SIM0500. SIM0500 The US FDA has recently approved several anti- GPRC5D ×CD3 and anti-BCMA×CD3 bispecific antibodies for patients with multiple myeloma (MM). Up to now, no tri-specific antibody has been approved for MM.  Previously, we reported the submission of the IND application for the phase 1 trial of SIM0500. The preclinical study showed the binding and efficacy data compared to teclistamab ( 特立妥单抗,  JNJ 7957) and  talquetamab (塔奎妥单抗,  JNJ 7564). Preclinical results of SIM0500 The phase 1 study for SIM0500 is focused on patients with refractory or relapsed multiple myeloma (rrMM) who have not responded to conventional standard-of-care treatments. Since no anti- GPRC5D ×CD3 and anti-BCMA×CD3 bispe

Sintanovo has submitted the IND application for STC008, a GHSR-1a agonist

 Sintanovo, a company of Sun-Novo,  has submitted the IND application for the  peptide  GHSR-1a agonist  STC008. This is the second Class 1 new drug candidate , following the first clinical-stage STC007, a peptide KOR agonist for postoperative pain relief . STC008 Growth hormone secretagogue receptor(GHS-R), also known as ghrelin receptor, a class A G protein-coupled receptor (GPCR), plays a diverse role in physiological functions, such as regulating appetite, alcohol intake, adipocyte metabolism, and maintaining glucose balance. GHSR1a, by binding with ghrelin, plays a significant role in stimulating appetite and increasing food intake. The role of GHS-R is thought to be in regulating energy homeostasis and body weight In 2020, anamorelin, a ghrelin receptor agonist, was approved as the world's first drug for the treatment of cancer cachexia in malignant tumors of non-small cell lung cancer, gastric cancer, pancreatic cancer, or colorectal cancer in Japan.  Unlike megestrol or cor

KH801: Pioneering the Future of CD24 Antibodies with Kanghong Pharma

Kanghong Pharma has initiated the phase 1 clinical trial of KH801, a humanized  anti-CD24 antibody, in patients with solid tumors. The China NMPA cleared the IND application of KH801 in March 2024. The first-in-human study was estimated to enroll 17-42 patients with 7 dose groups. Targeting the CD24-Siglec10 Axis KH801 KH801 eliminates tumor cells through Fc-mediated immune response and by inhibiting CD24/Siglec10 signaling in both. CD24, a small membrane protein heavily glycosylated and anchored by GPI, interacts with Siglec-10 on TAMs (Tumor-Associated Macrophages) to act as a 'don't eat me' signal, aiding tumor cells in evading macrophage engulfment. CD24 is prevalent across various solid tumors. In 2021, Kanghong applied for a patent ( WO2023104066 ) for using the anti-CD24 antibody or an antigen-binding fragment to treat tumors or immune diseases.  Kanghong presented the preclinical study results at the Society for Immunotherapy of Cancer's (SITC) 38th Annual Meet

InnoCare's Persistent Efforts to Bring Orelabrutinib to the American Market

 InnoCare has initiated the global phase 3 trial of orelabrutinib plus bendamustine and rituximab in patients with 1L MCL. Seeking opportunities in the United States In 2020, the China NMPA authorized the first market approval of Orelabrutinib for rrMCL and rrSSL/CLL. Then, in 2023, Orlabrutinib became the first BTK inhibitor for rrMZL in China. As announced at the 2024 J.P. Morgan Healthcare Conference, more than 30,000 patients have received Orelabrutinib, leading to an increase in annual sales to approximately 671 million RMB (equivalent to 93 million USD) at a rate of 18.5%. Orelabrutinib The United States is a dream destination for Chinese domestic biopharma, including InnoCare. According to InnoCare's presentation, they plan to submit an NDA seeking approval for rrMCL in the US in Q3 2024 . However, the FDA has become more strict in recent years regarding confirmatory trials for drugs that have conditional approvals. This action was taken because the promised trials were no
