新奇な標的治療を追求する中で、Gタンパク質共役型受容体クラスCグループ5メンバーD(GPRC5D)は、オーファンGタンパク質共役型受容体であり、最近、蔓延する様々な疾患に対する有望な治療標的として浮上してきました。GPRC5Dはがん治療、特に多発性骨髄腫のような血液悪性腫瘍の治療において、妥当な標的です。重要なことは、GPRC5Dの発現は主に形質細胞に限られており、正常組織にはほとんど存在しないことです。
現在、GPRC5Dを標的とする治療薬はタルベイ1剤のみであり、2003年8月にFDAより、免疫調節剤、プロテアソーム阻害剤、抗CD38抗体を含む少なくとも3種類の前治療を受け、最後の治療で病勢進行が認められた再発難治性多発性骨髄腫(RRMM)の成人患者に対する単剤療法として承認されています。世界市場では来年、より多くのGPRC5D治療薬の登場が予想されます。
とはいえ、GPRC5Dを標的とする治療法の領域では、前臨床試験に加え、多くの研究開発が進行中です。これらの研究の目的は、がん、特に多発性骨髄腫やその他の疾患の管理のために、先進的で画期的な新規GPRC5D療法を開発することです。例えば、オリセル・セラピューティクス社は、2024年4月に再発/難治性多発性骨髄腫患者を対象に、抗GPRC5D CAR-T細胞製剤(OriCAR-017)の安全性、薬物動態、薬力学、予備的有効性を評価するため、第I/II相非盲検多施設共同試験を開始しました。
GPRC5Dを標的とした治療における最近の進歩は、医学界に大きな関心と興奮をもたらしました。これらの治療法には、モノクローナル抗体、抗体薬物複合体(ADC)、キメラ抗原受容体(CAR)T細胞療法などの様々な革新的アプローチが含まれます。これらの治療法はいずれも、GPRC5Dのユニークな発現パターンを利用して、正常組織を温存しながら悪性細胞を選択的に標的にして根絶するもので、従来の治療法と比べてより良好な安全性プロファイルを提供できる可能性があります。
当レポートでは、世界のGPRC5D標的薬市場について調査し、市場の概要とともに、KRAS阻害剤の作用機序、癌治療における役割、地域別動向、臨床試験動向、および市場に参入する企業の競合動向などを提供しています。
Global GPRC5D Targeting Drugs Market Opportunity & Clinical Trials Insight 2024 Report Highlights:
In the pursuit for newfangled targeted therapies, G protein-coupled receptor class C group 5 member D or GPRC5D, an orphan G protein-coupled receptor, that has recently emerged as a promising therapeutic target for various diseases prevalent. GPRC5D is a plausible target in the realm of cancer care, particularly for the treatment of hematologic malignancies such as multiple myeloma. Importantly, GPRC5D expression is predominantly restricted to plasma cells, with minimal presence in normal tissues, making it an ideal target for therapeutic intervention due to its specificity.
Currently, only one GPRC5D targeting therapy, Talvey, has been approved by FDA, in August 2003, as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma (RRMM) who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody and have demonstrated disease progression on the last therapy. The upcoming year in the global market is anticipated to witness the advent of more GPRC5D therapies in future.
Nevertheless, copious research and development in addition to preclinical studies are ongoing in the GPRC5D targeting therapies domain. The aim of these studies is developed an advanced, groundbreaking and novel GPRC5D therapy for the management of cancer, chiefly multiple myeloma and other diseases. For instance, OriCell Therapeutics has begun a phase I/II, open-label, multicenter study in order to assess the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of anti-GPRC5D CAR-T cell product (OriCAR-017) in subjects with relapsed/refractory multiple myeloma in April 2024.
Recent advancements in GPRC5D targeting therapies have generated significant interest and excitement within the medical community. These therapies include a variety of innovative approaches such as monoclonal antibodies, antibody-drug conjugates (ADCs), and chimeric antigen receptor (CAR) T-cell therapies. Each of these modalities leverages the unique expression pattern of GPRC5D to selectively target and eradicate malignant cells while sparing normal tissues, thus potentially offering a more favorable safety profile compared to traditional treatments.
Amid all GPRC5D targeting therapeutic approaches, CAR T-cell therapies and bispecific antibodies are most used methods for the treatment of multiple myeloma as these modalities have shown particularly remarkable results. Introductory preclinical studies have exemplified that using CAR T cells coupled with bispecific antibody targeting GPRC5D can induce intense and durable remissions in patients with relapsed or refractory multiple myeloma. This is especially significant given the typically poor prognosis and limited treatment options for this patient population.
Interalia, the clinical development of GPRC5D targeting therapies is being rigorously pursued through a series of clinical trials designed to assess their safety, tolerability, and efficacy. Such as, Jiangsu Simcere Pharmaceutical in collaboration with Shanghai Xianxiang Medical Technology is planning to commence a phase 1 clinical trial, open-label, multicenter study to assess the safety, tolerability, effectiveness, and pharmacokinetics of SIM0500 in adult patients with relapsed or resistant multiple myeloma by May 2024.
These findings suggest that GPRC5D targeting therapies could potentially become a cornerstone in the treatment paradigm for multiple myeloma. Furthermore, the specificity of GPRC5D targeting therapies for plasma cells minimizes off target effects, which translates into a more manageable side effect profile for patients. This is a crucial consideration in cancer treatment, where treatment related toxicity can significantly impact the quality of life and overall outcomes for patients.
Several biopharmaceutical companies, such as AstraZeneca, Bristol Myers Squibb, Genmab, Johnson & Johnson, Roche and many more are actively engaged in the development of GPRC5D targeting therapies, with a focus on CAR T-cell products, monoclonal antibodies, and antibody drug conjugates.
Coupled with this, one of the fundamental prime movers which aid to expand the market of global GPRC5D targeting therapy is augmenting collaboration with global partners as well as expedited clinical trial approvals. For instance, in May 2023, LaNova Medicines, based in China, has signed a license agreement with UK based AstraZeneca Company to advance LaNova GPRC5D contender, LM-305. As per licensing agreement, AstraZeneca will have the solitary universal right to conduct research, develop and launch LM-305 in market.
In summary, GPRC5D targeting therapies represent a cutting-edge advancement in the treatment of multiple myeloma. Their development is driven by the unique expression pattern of GPRC5D, which allows for highly specific targeting of malignant plasma cells. As clinical trials continue to advance, there is optimism that these therapies will provide significant clinical benefits to patients, addressing a critical unmet need in the management of multiple myeloma along with other diseases in future.
