GPRC5D-directed Therapies Understanding

GPRC5D-directed Therapies Overview

GPRC5D, located on human chromosome 12p13, is an orphan G-protein coupled receptor, meaning that its ligand is unknown. GPRC5D is a validated target for multiple myeloma therapies. In early Phase trials, GPRC5D-targeting T-cell-redirecting agents have shown promising efficacy and manageable safety profiles, which need to be confirmed in Phase III trials.

GPRC5D is highly expressed in multiple myeloma cells and is abundant in the bone marrow of patients with multiple myeloma and smoldering multiple myeloma. Additionally, GPRC5D mRNA expression is also higher in multiple myeloma cells as compared to other hematologic cancers. The selective expression in multiple myeloma cells suggests that GPRC5D is an ideal target for immune effector cell-mediated therapy to treat multiple myeloma. GPRC5D-targeting T-cell-redirecting therapies, as monotherapy or in combination with other anti-myeloma agents, will expand the number of treatment options available for patients with multiple myeloma. These therapies may provide options for patients who may need treatment with a novel mechanism of action that preserves B-cell Maturation Antigen (BCMA)-targeting therapy for later lines of therapy, have experienced suboptimal response or antigen loss with other agents, or for patients who exhibit clonal heterogeneity. However, the optimal treatment sequence for patients with multiple myeloma will need to be elucidated.

While GPRC5D and BCMA have a similar expression on CD138+ cells, the expression patterns are independent of each other, offering distinct clinical targets. GPRC5D expression is also unaffected by BCMA loss, which has been associated with disease relapse following treatment with BCMA-targeting therapies and may support combining GPRC5D-targeting and BCMA-targeting T-cell redirecting agents to address the heterogeneity of multiple myeloma.

GPRC5D Epidemiology

The GPRC5D epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented as total cases in selected indications (multiple myeloma) for GPRC5D-directed therapies, total eligible patient pool in selected indications for GPRC5D-directed therapies, and total treated cases in selected indications for GPRC5D-directed therapies in the 7MM covering the United States, EU4 (Germany, France, Italy, and Spain), and the United Kingdom, and Japan from 2020 to 2034.

• In the US, there were around 33,700 incident cases of multiple myeloma in 2024, which was the highest among seven major markets.
• Multiple myeloma is more common in males as compared to females. In the United States, around 56% of males are diagnosed with multiple myeloma in 2024.
• When it comes to age-specific cases of multiple myeloma, the age group of 65 and above years has the highest number of cases, followed by 55-64 and 0-54 years.
• In Japan, there were nearly 5,400 first-line transplant ineligible cases and nearly 1,300 first-line transplant eligible cases in 2024.

Arlocabtagene autoleucel (BMS-986393): Bristol Myers Squibb (Juno Therapeutics)

BMS-986393 is a GPRC5D-directed autologous CAR T cell therapy. The company is currently conducting a Phase II (QUINTESSENTIAL) trial in relapsed/refractory multiple myeloma with projected data readout in 2026. At the ASH 2023 conference updated data from the Phase I study of BMS-986393, showed deepening responses, a tolerable safety profile, and activity across both B-cell maturation antigen (BCMA)-naive and -exposed patients.

GPRC5D Market Outlook

GPRC5D has emerged as a promising therapeutic target for treating multiple myeloma. Preclinical studies have demonstrated the efficacy of GPRC5D CAR-T cells using a human-derived GPRC5D-targeted scFv clone 109 (GPRC5D[109]) in various multiple myeloma cell lines, including primary cells from bone marrow aspirates. Ongoing trials are exploring the safety and effectiveness of combining these T-cell-redirecting agents with other anti-myeloma treatments for patients with relapsed or refractory multiple myeloma. These combinations include talquetamab with teclistamab, daratumumab, pomalidomide, anti-PD-1 antibodies, carfilzomib, and lenalidomide. This suggests that GPRC5D-targeting bispecific antibodies could be versatile partners in combination therapies. However, managing GPRC5D-associated adverse events requires further investigation into dose modification strategies, such as reduced frequency or fixed-duration dosing, and other mitigation measures. These approaches aim to balance the potential toxicity related to on-target effects with the promising efficacy seen in these therapies. In addition to CAR-T therapies, ongoing research includes CAR-natural killer cell therapies, bispecific-natural killer cell engagers, and antibody-drug conjugates, which collectively offer potential advancements in treating multiple myeloma.

Additionally, clinical trials, including those investigating GPRC5D-targeting T-cell-redirecting agents in combination with other anti-myeloma therapies and with different treatment modalities, may help to elucidate the future optimal treatment regimen and sequence for patients with multiple myeloma and improve survival outcomes.

Key players in the GPRC5D market include CARsgen Therapeutics, Oricell, Bristol-Myers Squibb, AstraZeneca, Sanofi, and others.
