CD3 x CD22

Regeneron's revised R&D road map includes the study of the bispecific as a monotherapy. Regeneron is rethinking development of its prostate cancer bispecific after two patients died in a clinical trial. The deaths prompted the Big Biotech to stop enrolling patients to receive REGN5678 and a full dose of its checkpoint inhibitor, but a reshaped bispecific development program is continuing.  REGN5678 is designed to bind to CD28 on cytotoxic T-lymphocytes (CTLs) and PSMA on tumor cells. By binding to the costimulatory T-cell-specific surface glycoprotein and tumor-associated antigen, the drug candidate could activate CTLs and direct them to attack cancer cells. Regeneron identified the targeting of CD28 on previously activated T cells as a way to reduce toxicity compared to CD3 bispecifics.  The candidate, which may synergize with anti-PD-1/L1 checkpoint inhibitors, came through the release of preliminary phase 1/2 data unscathed. But safety concerns have since come to light and prompted a shift in the R&D strategy. In its second-quarter results statement, Regeneron reported two immune-mediated deaths in a cohort of patients who received REGN5678 in combination with Libtayo, the company’s checkpoint inhibitor. The deaths drove Regeneron to stop enrolling patients to receive REGN5678 and a full dose of Libtayo. Regeneron is sticking with the candidate, though. The revised R&D road map includes the study of the bispecific as a monotherapy and in combination with lower doses of Libtayo and other immunotherapy modalities. Regeneron’s other costimulatory bispecific development programs, which include candidates against EGFR, MUC16 and CD22, are unaffected and are still making their way through dose escalation.  Even so, the removal of the option to pair REGN5678 with a full dose of Libtayo is a blow. Regeneron took the bispecific into the clinic in the belief the combination may be able to overcome the resistance of metastatic castration-resistant prostate cancer to PD-1 inhibition. Overcoming resistance could bring the benefits of checkpoint inhibitors to prostate cancer, a setting in which the drugs have had little impact. CD28 has a troubled history as a cancer target. The CD28 superagonist TGN1412 caused critical illnesses linked to cytokine storms in a phase 1 clinical trial in 2006. In recent years, companies including Johnson & Johnson and Sanofi have invested in candidates against the target, but fresh concerns emerged last year, when two deaths stopped trials of Alpine Immune Sciences’ conditional costimulator of CD28.

SHANGHAI and NANJING, China and SAN JOSE, Calif., June 12, 2022 /PRNewswire/ -- IASO Biotherapeutics ("IASO Bio"), a clinical-stage biopharmaceutical company engaged in discovering, developing, and manufacturing innovative cell therapies and antibody products, and Innovent Biologics, Inc. ("Innovent," HKEX: 01801), today jointly announced that the updated data from phase 1/2 study of Equecabtagene Autoleucel (IASO Bio R&D code: CT103A, Innovent R&D code: IBI326), a fully-human anti-B cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapy for the treatment of relapsed and/or refractory multiple myeloma (R/R MM), was presented in the form of an oral presentation at the 27th European Hematology Association (EHA) Annual Meeting in Vienna on June 9-12, 2022. Presentation Title: Updated Phase 1/2 Data of the Safety and Efficacy of CT103A, Fully-Human BCMA-Directed CAR-T Cells in Relapsed/Refractory Multiple Myeloma Session Title: Relapsed/refractory myeloma: BCMA-directed therapies Abstract Code: EHA-S187 Session date and Time: Sunday, June 12, 2022, at 11:30 AM - 12:45 PM CEST Place: Vienna, Austria or online Speaker: Chunrui Li, MD, Ph.D., from Department of Hematology, Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology The updated data from the Phase 1/2 study with a longer duration of follow-up in more patients has showed durable and deepening efficacy, manageable safety and long-term in vivo persistence, indicating that Equecabtagene Autoleucel has the potential to be a breakthrough therapy for patients with R/R MM. The updated data is from the 14 clinical sites involved in the Phase 1/2 clinical study of Equecabtagene Autoleucel (ChiCTR1800018137, NCT05066646) in the treatment of patients with R/R MM. As of the data cutoff date of January 21, 2022, 79 patients received recommended phase 2 dose（RP2D）of 1.0×106 CAR-T cells/kg with the median follow-up of nine months (range 1.2, 19.6) and median prior five lines of therapy(range 3,23). Among the 79 patients, 34.2% (27/79) had high-risk cytogenetic abnormalities, 34.2%（27/79）had extramedullary multiple myeloma (EMM), and 15.2%（12/79）had received prior CAR-T therapy. Equecabtagene Autoleucel demonstrated a favorable and manageable safety profile: Among the 79 patients, 94.9% (75/79) experienced cytokine release syndrome (CRS). The majority experienced 1~2 CRS, and no patient experienced grade 3 CRS. The median time to CRS onset was six days after infusion, and the median duration of CRS was five days. Only two patients experienced immune effector cell-associated neurotoxicity syndrome (ICANS), including one patient who experienced grade 1 ICANS and one who experienced grade 2 ICANS. All patients with CRS or ICANS have recovered. Equecabtagene Autoleucel showed favorable and durable efficacy: Among the 79 patients, the overall response rate (ORR) was 94.9% (75/79), with 89.9 (71/79) of those patients achieving very good partial response (VGPR) or deeper responses, and the complete response/stringent complete response (CR/sCR) rate was 68.4% (54/79). Equecabtagene Autoleucel also demonstrated favorable efficacy in 10 patients with EMM, achieving an ORR of 100% (10/10) and a CR/sCR rate of 90.0% (9/10). In all 79 patients, 92.4% (73/79) achieved minimal residual disease (MRD) negativity, all CR/sCR subjects achieved MRD negativity, and the median duration of MRD negativity was not reached. Equecabtagene Autoleucel demonstrated favorable efficacy in patients who had received prior CAR-T therapy: Among the 12 patients who previously received CAR-T therapy, the ORR was 75.0% (9/12), with 41.7% (5/12) of those patients achieving CR/sCR. Equecabtagene Autoleucel demonstrated robust expansion and prolonged persistence: The expansion of Equecabtagene Autoleucel in peripheral blood reached the peak at a median of 12 days, with a median Cmax of 92,000 copies/ug DNA. Equecabtagene Autoleucel was still detectable in 62.3% (38/61) and 53.3% (8/15) of the subjects who completed 6-months and 12-month follow-ups after infusion. Soluble BCMA in peripheral blood of patients rapidly declined after Equecabtagene Autoleucel infusion and persistently remained below the detectable limit. Equecabtagene Autoleucel has low immunogenicity: 16.5% (13/79) of the subjects tested anti-drug antibody (ADA)-positive after Equecabtagene Autoleucel infusion. Among them，1.3% (1/79) tested ADA-positive before Equecabtagene Autoleucel infusion, and 2.5% (2/79) tested ADA-positive within three months. "Chimeric antigen receptor (CAR)-T cell therapy is a revolutionary new pillar in cancer treatment. In our previous studies, Equecabtagene Autoleucel has shown excellent efficacy and manageable safety profiles. Its CAR structure contains fully human single-chain fragment variables (scFvs) to bypass potential anti-CAR immunogenicity of the host while retaining antitumor activity. At the 27th EHA conference, we updated the data on the efficacy and safety of Equecabtagene Autoleucel in R/R MM patients with longer median follow-up extended to 9.0 months, the CR/sCR deepened to 68.4%, compared with the CR/sCR of 58.2% with a median follow-up of 7.0 months, which were released at 63rd ASH conference in 2021. The updated data showed long-lasting safety and deepening efficacy of Equecabtagene Autoleucel. We are glad that Equecabtagene Autoleucel also shows favorable efficacy on patients who have relapsed after receiving prior CAR-T therapy. This has meaningful clinical value and is worthy of further exploration in the clinic to potentially bring forth new hope to patients with R/R MM." Prof. Chunrui Li, MD, PhD, from Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology. About Multiple Myeloma (MM) Multiple Myeloma is a deadly blood cancer that often infiltrates the bone marrow causing anemia, kidney failure, immune problems, and bone fractures. For multiple myeloma patients, common first-line drug treatments include proteasome inhibitors, immunomodulatory drugs, and alkylating agents. While treatment may result in remission, most patients will inevitably enter the relapsed or refractory stage as there's currently no cure. As a result, there is a significant unmet need for patients with relapsed/refractory multiple myeloma. In the United States, MM accounts for nearly 2% of new cancer cases and more than 2% of all cancer-related deaths. According to Frost & Sullivan, the number of new MM cases in the United States rose from 30,300 in 2016 to 32,300 in 2020 and is expected to increase to 37,800 by 2025. Additionally, the total number of patients diagnosed with MM increased from 132,200 in 2016 to 144,900 in 2020 and is expected to rise to 162,300 by 2025. In China, the number of new MM cases rose from 18,900 in 2016 to 21,100 in 2020 and is expected to increase to 24,500 by 2025. The total number of patients diagnosed with MM in China increased from 69,800 in 2016 to 113,800 in 2020 and is expected to rise to 182,200 by 2025.

Long-term data at the European Hematology Association (EHA) 2022 congress expands understanding of the impact of Roche medicines in early-stage blood cancers with the goal of providing patients with robust and durable outcomes from their first treatment Updated data from phase III CLL14 study of Venclexta®/Venclyxto® (venetoclax) plus Gazyva®/Gazyvaro® (obinutuzumab) showed more than 60% of previously untreated people with chronic lymphocytic leukaemia remained in remission five years after starting treatment[1] Final analysis of phase III GALLIUM study showed meaningful improvement in progression-free survival was maintained with Gazyva/Gazyvaro plus chemotherapy in people with previously untreated follicular lymphoma after eight years of follow-up[2] Basel, 10 June 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that it is presenting new long-term follow-up results and subanalyses from clinical trials of its approved therapies, as well as data on investigational medicines from its broad blood cancer portfolio, at the European Hematology Association (EHA) 2022 Congress in Vienna. Data include five-year results from the phase III CLL14 study of fixed-duration Venclexta®/Venclyxto® (venetoclax) plus Gazyva®/Gazyvaro® (obinutuzumab) in previously untreated chronic lymphocytic leukaemia (CLL); the final analysis of the phase III GALLIUM study of Gazyva/Gazyvaro plus chemotherapy in people with previously untreated advanced-stage follicular lymphoma (FL); and subanalyses from the phase III POLARIX study of Polivy® (polatuzumab vedotin) in combination with MabThera®/Rituxan® (rituximab) plus cyclophosphamide, doxorubicin and prednisone (R-CHP) in people with previously untreated diffuse large B-cell lymphoma (DLBCL). Roche will also present data from its T-cell engaging bispecific antibody development programmes including Lunsumio® (mosunetuzumab) and glofitamab in patients receiving later lines of therapy for non-Hodgkin lymphoma (NHL) and investigational medicines cevostamab and RG6234 in relapsed or refractory (R/R) multiple myeloma (MM).“Blood cancers remain challenging to treat at all stages, but by improving frontline treatment options we aim to increase the likelihood of meaningful clinical outcomes for these patients,” said Levi Garraway, M.D., Ph.D., Chief Medical Officer and Head of Global Product Development. “With these new long-term data and other studies of fixed-duration therapies in our portfolio, we are working to lessen the treatment burdens associated with long-term cancer care.”Improving clinical outcomes with effective frontline treatment optionsFive-year results of phase III CLL14 study of Venclexta/Venclyxto plus Gazyva/Gazyvaro (Abstract #S148)After a median of 65.4 months following treatment with Venclexta/Venclyxto plus Gazyva/Gazyvaro, results confirm the combination continues to be an effective fixed-duration and chemotherapy-free option for patients with previously untreated CLL and coexisting conditions. The estimated investigator-assessed progression-free survival (PFS) rate at this follow-up was 62.6% with Venclexta/Venclyxto plus Gazyva/Gazyvaro and 27.0% with Gazyva/Gazyvaro plus chlorambucil, and the estimated overall survival (OS) rate was 81.9% versus 77.0% (HR 0.72; 95% CI: 0.48-1.09; p=0.12). In addition, the analysis found that 72.1% of patients in the Venclexta/Venclyxto plus Gazyva/Gazyvaro arm did not require another treatment for CLL in the five years following initial treatment (HR 0.42; 95% CI: 0.31-0.57; p<0.0001). No new safety signals were observed.[1] The CLL14 study is being conducted in cooperation with the German CLL Study Group, headed by Michael Hallek, M.D., University of Cologne.Final analysis of phase III GALLIUM study of Gazyva/Gazyvaro (Abstract #S206)After eight years of follow-up in people with previously untreated FL, a meaningful improvement in PFS was maintained with Gazyva/Gazyvaro plus chemotherapy, confirming its role as a standard of care for first-line treatment. Seven-year investigator-assessed PFS was significantly improved with Gazyva/Gazyvaro plus chemotherapy (63.4%) compared with MabThera/Rituxan plus chemotherapy (55.7%; HR 0.77; 95% CI: 0.64-0.93; p=0.006). This translated into a longer time to next anti-lymphoma treatment. At seven years, 74.1% of patients receiving Gazyva/Gazyvaro plus chemotherapy had not started new anti-lymphoma therapy compared to 65.4% receiving MabThera/Rituxan plus chemotherapy (HR 0.71; 95% CI: 0.58–0.87; p=0.001). The incidence of serious adverse events was 48.9% with Gazyva/Gazyvaro plus chemotherapy and 43.4% with MabThera/Rituxan plus chemotherapy.[2] Subgroup analyses of pivotal phase III POLARIX study (Abstract #P1192) Exploratory subgroup analyses of the phase III POLARIX study of Polivy with R-CHP compared to the current standard of care, MabThera/Rituxan plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP), in people with previously untreated DLBCL further support the potential for Polivy to transform the standard of care for people with this aggressive type of lymphoma. One of the datasets being presented is an analysis of study participants from Asia (China, Hong Kong, Japan, South Korea and Taiwan). Among this subgroup, results showed a significant improvement in PFS with Polivy plus R-CHP versus R-CHOP, reducing the risk of disease progression, relapse or death by 36% (HR 0.64; 95% CI: 0.40-1.03). The safety profile was generally comparable for both regimens.[3] Based on the positive POLARIX results from the overall study population, the European Commission (EC) approved Polivy plus R-CHP in May 2022 for the treatment of adult patients with previously untreated DLBCL.Providing novel bispecific antibodies for patients receiving later lines of therapy in lymphoma and beyondPivotal data from phase II NP30179 expansion study of glofitamab (Abstract #S220)The pivotal phase II NP30179 expansion study included patients with heavily pre-treated and highly refractory DLBCL and showed fixed-duration glofitamab, an investigational CD20xCD3 T-cell engaging bispecific antibody, induced high and durable complete response (CR) rates. After a median follow-up of 12.6 months, 39.4% of patients (n=61/155) achieved a CR (primary efficacy endpoint) and half of them (51.6%; n=80/155) achieved an overall response (the percentage of patients with a partial or CR; secondary efficacy endpoint), as assessed by an independent review committee. Cytokine release syndrome (CRS) was the most common adverse event, occurring in 63.0% of patients.[4] These data were recently presented at the American Society of Clinical Oncology 2022 Annual Meeting and have been submitted for approval to the European Medicines Agency (EMA). Submissions to additional health authorities worldwide, including the U.S. Food and Drug Administration (FDA), are planned this year.Subgroup analysis and Lunsumio retreatment from pivotal phase II GO29781 study (Abstracts #P1126 and #P1124)An exploratory subgroup analysis showed Lunsumio could be an efficacious and tolerable option in patients aged <65 and ≥65 years who had R/R FL and had received two or more prior therapies. Patients ≥65 years old achieved a higher objective response rate (ORR) than those <65 years old (87.0% vs 77.0%, respectively). Lower rates of CRS and serious adverse events were observed in patients ≥65 years old (37%) compared to those <65 years old (52%).[5] Additional data from the GO29781 study showed that retreatment with Lunsumio in patients who achieved a CR but whose disease subsequently progressed was effective and the safety of retreatment was consistent with initial treatment.[6]The EC recently approved Lunsumio for the treatment of people with R/R FL who have received at least two prior systemic therapies.The data being presented at EHA, as well as phase III studies currently underway, will expand the understanding of glofitamab and Lunsumio and their impact in both later and earlier lines of treatment, with the aim of providing robust and durable treatment outcomes for people with different types of lymphomas.Early data from novel investigational bispecific antibodies in R/R MM (Abstracts #P962 and #S180)In line with Roche’s commitment to improving outcomes and personalising care for people with blood cancer, the company has expanded beyond lymphoma and leukaemia, evaluating two investigational medicines in MM. This is the third most common type of blood cancer, diagnosed in more than 170,000 people around the world each year and involves plasma cells (antibody-producing cells in the bone marrow).[7,8] Although advances in treatment have improved outcomes, MM remains an incurable disease characterised by multiple relapses, with an overall five-year survival rate of about 55%.[9] Roche is presenting data at EHA on cevostamab, an investigational FcRH5xCD3 T-cell engaging bispecific antibody that is being evaluated as a monotherapy and in combination with other medicines to treat people with R/R MM, and on RG6234, a novel GPRC5DxCD3 T-cell engaging bispecific antibody that is being studied in a phase I trial in people with R/R MM. While early, the clinical activity and safety profiles observed with these molecules look encouraging and support further exploration.[10,11] About Venclexta®/Venclyxto® (venetoclax)Venclexta/Venclyxto is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumours, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta/Venclyxto blocks the BCL-2 protein and works to help restore the process of apoptosis.Venclexta/Venclyxto is being developed by AbbVie and Roche. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the US and commercialised by AbbVie outside of the US. Together, the companies are committed to research with Venclexta/Venclyxto, which is currently being studied in clinical trials across several types of blood cancers.In the US, Venclexta has been granted six Breakthrough Therapy Designations by the U.S. Food and Drug Administration: one for previously untreated chronic lymphocytic leukaemia (CLL), two for relapsed or refractory CLL, two for previously untreated acute myeloid leukaemia, and one for myelodysplastic syndromes.About Gazyva®/Gazyvaro® (obinutuzumab)Gazyva/Gazyvaro is an engineered monoclonal antibody designed to attach to CD20, a protein found only on certain types of B-cells. It is thought to work by attacking targeted cells both directly and together with the body's immune system. Gazyva/Gazyvaro is part of a collaboration between Roche and Biogen. In the US, Europe and multiple other countries, Gazyva/Gazyvaro is currently approved in combination with chlorambucil for patients with previously untreated chronic lymphocytic leukaemia (CLL). It is also approved in combination with bendamustine, followed by Gazyva/Gazyvaro maintenance for the treatment of follicular lymphoma (FL) patients who did not respond to a MabThera®/Rituxan® (rituximab)-containing regimen, or whose FL returned after such treatment and in combination with chemotherapy for previously untreated advanced FL.Additional combination studies investigating Gazyva/Gazyvaro with other approved or investigational medicines, including cancer immunotherapies and small molecule inhibitors, are underway across a range of blood cancers.About Polivy® (polatuzumab vedotin)Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B-cells, an immune cell impacted in some types of non-Hodgkin lymphoma (NHL), making it a promising target for the development of new therapies.[12,13] Polivy is designed to bind to CD79b and destroys these B-cells through the delivery of an anti-cancer agent, which is thought to minimise the effects on normal cells.[14,15] Polivy is being developed by Roche using Seagen ADC technology and is currently being investigated for the treatment of several types of NHL.About Roche’s investigational CD20xCD3 bispecifics in haematologyRoche is currently developing two CD20xCD3 T-cell engaging bispecific antibodies, Lunsumio® (mosunetuzumab) and glofitamab, designed to target CD20 on the surface of B-cells and CD3 on the surface of T-cells. This dual targeting activates and redirects a patient’s existing T-cells to engage and eliminate target B-cells by releasing cytotoxic proteins into the B-cells. Lunsumio and glofitamab differ in their structures, and both are being developed by Roche as part of our ongoing strategy to explore multiple bispecific formats in order to identify those that maximise potential clinical benefits for patients. Lunsumio has a structure similar to that of a natural human antibody in that it has two ‘Fab’ regions but is different from naturally-occurring antibodies in that one ‘Fab’ region targets CD20 and the other ‘Fab’ region targets CD3. Glofitamab is based on a novel structural format that we call ‘2:1,’ which refers to the structure of the antibody. It is engineered to have two ‘Fab’ regions that bind to CD20 and one ‘Fab’ region that binds to CD3. The clinical development programmes for Lunsumio and glofitamab include ongoing investigations of these molecules as monotherapies and in combination with other medicines for the treatment of people with CD20-positive B cell non-Hodgkin lymphomas, including diffuse large B-cell lymphoma and follicular lymphoma.About Roche Founded in 1896 in Basel, Switzerland, as one of the first industrial manufacturers of branded medicines, Roche has grown into the world’s largest biotechnology company and the global leader in in-vitro diagnostics.
