    According to PDUFA's expected target date, it is expected that in November, the US FDA will make a regulatory decision
    on the approval of 3 innovative drugs.
    If the approval process is faster, another innovative drug is expected to be approved
    in November.

    Name of the drug: Teplizumab

    Name of the drug: Teplizumab

    Company name: Provention Bio

    Company name: Provention Bio

    Indications: Type 1 diabetes mellitus

    Indications: Type 1 diabetes mellitus

    Provention Bio's teplizumab is a monoclonal antibody drug that targets CD3 antigens on the surface of T cells, which can weaken the autoimmune attack on islets β cells, thereby protecting β cells from destruction, thereby preventing or delaying the onset
    of type 1 diabetes.
    For people who are genetically susceptible to type 1 diabetes, the disease has begun to develop before the appearance of obvious symptoms of hyperglycemia, mainly manifested as the appearance of autoantibodies (anti-insulin and anti-pancreatic antibodies, etc.
    ) and abnormal
    glucose tolerance.
    During this time, β cells in the pancreas remain largely intact, providing a vital window
    to intervene and preserve β cells.
    Currently, there is a lack of ways to
    prevent the onset of type 1 diabetes in high-risk groups.

    In people with a genetic predisposition to type 1 diabetes, the disease has begun to develop before symptoms of significant hyperglycemia appear

    FDA received teplizumab's Application for Biological Product Licensing (BLA) with a PDUFA date set for November 17
    , 2022.
    If approved, it would be the first therapy
    to change the course of type 1 diabetes.
    Previously, the FDA had granted Teplizumab breakthrough therapy designation
    .
    Phase 2 clinical results show that teplizumab can delay the onset of type 1 diabetes by 2 years or more
    .
    The median time to diagnosis of type 1 diabetes in the Teplizumab group was 48.
    4 months, compared with 24.
    4 months
    in the placebo group.
    Teplizumab was statistically shown to reduce the risk of developing type 1 diabetes by 59% (HR = 0.
    41; 95% CI, 0.
    22 - 0.
    78; P=0.
    006), the results of this trial were published in the New England Journal of Medicine
    .
    In early October, Sanofi obtained co-commercialization rights for
    the drug.

    If approved, it would be the first therapy to change the course of type 1 diabetes disease with a 59% lower risk

    Drug name: Etranacogene dezaparvovec

    Drug name: Etranacogene dezaparvovec

    Company name: CSL Behring/uniQure

    Company Name: CSL Behring/uniQureCSL Behring/

    Indications: Hemophilia B

    Indications: Hemophilia B

    etranacogene by CSL Behring/uniQure Dezaparvovec is a gene therapy designed to deliver transgenes
    expressing a variant of coagulation factor IX (FIX) Padua using an AAV5 vector.
    This FIX variant has higher FIX activity, meaning normal clotting can
    be done at lower expression levels.
    Hemophilia B is a life-threatening degenerative disease in which patients have a mutation in the gene encoding FIX, resulting in a FIX deletion or defect.

    Patients with the condition are prone to bleeding from joints, muscles, and internal organs, resulting in pain, swelling, and joint damage
    .
    Current treatment includes lifelong prophylactic FIX transfusions to temporarily replace or replace low levels of clotting factors
    .

    Hemophilia B is a life-threatening degenerative disease in which patients have a mutation in the gene encoding FIX, resulting in a FIX deletion or defect

    The FDA received the drug's BLA at the end of May this year and granted it priority review status, with the PDUFA date set for November 24
    , 2022.
    If approved, it would be the first gene therapy
    to treat hemophilia B.
    This BLA is based on the results
    of the Phase 3 clinical trial HOPE-B.
    The results of the trial showed that the annual bleeding rate (ABR) of patients treated with one-time gene therapy was reduced by 64% (p=0.
    0002)
    after 18 months of treatment compared with the lead-in period before treatment.
    It is worth mentioning that this trial is the first to study the efficacy
    of this gene therapy in patients who carry adeno-associated virus neutralizing antibodies in their bodies.
    The results of the trial showed that no evidence
    of neutralizing antibodies affecting FIX activity was found in patients with a neutralizing antibody titer of up to 678.

    Drug name: Mirvetuximab soravtansine

    Drug name: Mirvetuximab soravtansine

    Company name: ImmunoGen

    Company name: ImmunoGen

    Indications: Advanced ovarian cancer

    Indications: Advanced ovarian cancer

    ImmunoGen's mirvetuximab Soravtansine is an antibody-conjugated drug (ADC)
    that targets folate receptor α (FRα).
    FRα is a member of the folate receptor family, and studies have shown that FRα is highly expressed
    in 76-89% of epithelial ovarian cancers and 35-68% of triple-negative breast cancers.
    FRα-mediated signaling pathways can affect tumor cell division and migration, and inhibition of FRα may produce a certain degree of direct anticancer activity
    .
    Of all the gynaecological cancers, ovarian cancer is one
    of the deadlier.
    Due to the lack of specific symptoms, most patients are already at an advanced stage (stage III or IV) when they are diagnosed
    .

    FRα is highly expressed in 76-89% of epithelial ovarian cancers and 35-68% of triple-negative breast cancers

    The FDA received the drug's BLA at the end of May this year and granted it priority review status, with the PDUFA date set for November 28, 2022
    。 This BLA is based on results from a Phase 3 clinical trial SORAYA, which showed that patients with platinum-resistant ovarian cancer whose tumors expressed high levels of FRα received mirvetuximab With soravtansine administration with a median follow-up of 8.
    1 months, patients achieved an objective response rate (ORR) of 32.
    4% (95% CI: 23.
    6%, 42.
    2%), including 5 complete remissions (CR).

    It is worth mentioning that in October 2020, Huadong Pharmaceutical obtained the exclusive development and commercialization rights
    of the drug in Greater China for more than 300 million US dollars.

    Name of the drug: Adagrasib

    Name of the drug: Adagrasib

    Company name: Mirati Therapeutics

    Company name: Mirati Therapeutics

    Indications: Non-small cell lung cancer

    Indications: Non-small cell lung cancer

    Mirati Therapeutics' adagrasib is a highly specific powerful oral KRAS G12C inhibitor optimized for long-lasting target inhibition
    .
    Adagrasib has a half-life of up to 24 hours and a wide tissue distribution, and is able to cross the blood-brain barrier, helping to maximize the drug's potency
    .
    Studies have shown that KRAS mutations and wild-type KRAS amplification are frequently seen
    in patients with colorectal cancer (~45% in the US, ~49% in China), pancreatic cancer (~90% in the US, ~87% in China), and non-small cell lung cancer (NSCLC, ~35% in the US, ~13% in China).
    Among them, KRAS G12C is the most common KRAS mutation in patients with NSCLC, occurring in 14% of lung adenocarcinomas, and patients generally have a poor
    prognosis.

    Being able to cross the blood-brain barrier helps maximize the effectiveness of the drug

    The FDA received a New Drug Application (NDA) for the drug in early February of this year, with the PDUFA date set for December 14
    , 2022.
    The NDA application uses the FDA's real-time oncology review (RTOR) pilot program, which means the drug could be approved
    as early as November.
    This NDA is based on cohort results
    from the Phase 2 clinical trial KRYSTAL-1.
    While carrying KRAS In patients with advanced NSCLC with G12C mutations, adagrasib achieved an objective response rate (ORR) of 43% and a disease control rate (DCR)
    of 80%.
    Previously, the drug was granted breakthrough therapy designation
    by the US FDA.
    In China, Zai Lab has rights to develop this innovative therapy in Greater China
    .
    The query of the drug clinical trial registration and information disclosure platform shows that the drug is used in KRAS in China Clinical trials in NSCLC patients with G12C mutations have entered the phase 3 clinical trial stage
    up to phase 3.

    Real-time oncology review (RTOR) pilot project, which means that the drug may be approved in China as early as November, Zai Lab has the rights
    to develop this innovative therapy in Greater China.
