TCRX: TScan Therapeutics Receives FDA’s Regenerative Medicine Advanced Therapy (RMAT) Designation for its Two Lead TCR-T Therapy Candidates for the Treatment of Heme Malignancies

https://finance.yahoo.com/news/tscan-therapeutics-receives-fda-regenerative-110000336.html

TScan Therapeutics, Inc.
RMAT designation granted for both TSC-100 and TSC-101 for the treatment of patients with AML, ALL, and MDS undergoing allogeneic HCT with reduced intensity conditioning

WALTHAM, Mass, May 29, 2024 (GLOBE NEWSWIRE) -- TScan Therapeutics, Inc. (Nasdaq: TCRX), a clinical-stage biopharmaceutical company focused on the development of T cell receptor (TCR)-engineered T cell (TCR-T) therapies for the treatment of patients with cancer, today announced that the U.S. Food and Drug Administration (FDA) has granted Regenerative Medicine Advanced Therapy (RMAT) designation to TSC-100 and TSC-101, the Company’s two lead TCR-T therapy candidates for the treatment of heme malignancies (NCT05473910).

“We are delighted to receive FDA RMAT designation for both candidates in our heme program designed to treat patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic cell transplantation (HCT) with reduced intensity conditioning, based on encouraging initial data from the ALLOHA trial,” said Chrystal U. Louis, M.D., Chief Medical Officer. “This is an important milestone that recognizes the transformative potential of our engineered TCR-T therapy candidates, TSC-100 and TSC-101, in multiple difficult-to-treat cancers. We look forward to working closely with the FDA in our ongoing commitment to deliver life-changing therapies to patients.”

Established under the 21st Century Cures Act, RMAT designation is a dedicated program designed to expedite the drug development and review processes for promising pipeline products, including gene and cell therapies. A regenerative medicine therapy is eligible for RMAT designation if it is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or therapy has the potential to address unmet medical needs for such a disease or condition. Like Breakthrough Therapy designation, RMAT designation provides the benefits of intensive FDA guidance on efficient drug development, including the ability for early interactions with FDA to discuss surrogate or intermediate endpoints, potential ways to support accelerated approval and satisfy post-approval requirements, potential priority review of an Investigational New Drug (IND) application, and other opportunities to expedite development and review.

TScan has developed two lead TCR-T therapy candidates, TSC-100 and TSC-101, that target minor histocompatibility antigens HA-1 and HA-2, respectively. TScan is prospectively selecting HLA A*02:01-positive transplant patients who are either HA-1- or HA-2-positive, with donors who are negative for these antigens. In this context, TSC-100 and TSC-101 are designed to eliminate all recipient hematopoietic cells, including malignant, pre-malignant or normal cells, that persist post-transplant, while leaving donor-derived cells unaffected. Approximately 40% of patients with AML, ALL, and MDS who undergo allogeneic haploidentical HCT with reduced intensity conditioning relapse within two years of transplant, at which point there are limited treatment options and poor prognosis. The goal of this program is to increase the cure-rate for patients receiving HCT.

On May 13, 2024, the Company provided an update on its Phase 1 heme malignancies program. The update included additional follow-up on all eight treatment-arm patients as well as data on two additional control-arm patients. With a median follow-up of >10 months, all eight patients treated with TSC-100 or TSC-101 remain relapse-free with no detectable disease. No dose-limiting toxicities were observed. In contrast, two of eight control-arm patients relapsed approximately six months post-transplant and one of these patients died approximately three months later. A third control-arm patient required clinical intervention because of concerns of impending relapse, and a fourth control-arm patient died post-transplant.

Interesting FDA approval for Amgen today - Bispecific T-cell Engager

https://finance.yahoo.com/news/fda-approves-imdelltra-tarlatamab-dlle-224500427.html

Breakthrough DLL3-Targeting Therapy Regimen for a Major Solid Tumor

IMDELLTRA Demonstrated Impressive 40% Objective Response Rate, 9.7 Month Median Duration of Response and 14.3 Month Median Overall Survival in Pivotal DeLLphi-301 Study

Amgen to Host Webcast Investor Call on May 20, 2024 at 1:00 p.m. PT

THOUSAND OAKS, Calif., May 16, 2024 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced that the U.S. Food and Drug Administration (FDA) has approved IMDELLTRA™ (tarlatamab-dlle) for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy. IMDELLTRA has received accelerated approval based on the encouraging response rate and duration of response (DoR) observed in clinical studies. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

"The FDA's approval of IMDELLTRA marks a pivotal moment for patients battling ES-SCLC. This DLL3-targeting therapy in ES-SCLC comprises a transformative option demonstrating long-lasting responses in pretreated patients," said Jay Bradner, M.D., executive vice president, Research and Development, and chief scientific officer at Amgen. "This approval further demonstrates our commitment to addressing aggressive cancers through our second FDA-approved Bispecific T-cell Engager (BiTE®) molecule. IMDELLTRA offers these patients who are in urgent need of new innovative therapies hope, and we're proud to deliver this long-awaited effective treatment to them."

"Lung cancer is a complex and devastating disease, and less than 3% of patients with ES-SCLC live longer than five years," said David P. Carbone, M.D., Ph.D., professor of internal medicine and director of the James Thoracic Oncology Center at the Ohio State University Medical Center.1 "In the DeLLphi-301 trial, the median overall survival was 14.3 months, with 40% of patients responding to treatment with tarlatamab. These responses were remarkably durable, representing a major advancement in the SCLC treatment paradigm."

IMDELLTRA is the first and only DLL3-targeting Bispecific T-cell Engager therapy that activates the patient's own T cells to attack DLL3-expressing tumor cells.2

"After decades of minimal advancements in the SCLC treatment landscape, there is now an effective and innovative treatment option available," said Laurie Fenton Ambrose, co-founder, president, and CEO of GO2 for Lung Cancer. "Today's FDA approval marks a significant milestone for the SCLC community as the availability of a targeted bispecific therapy brings forward new possibilities to those living with this aggressive disease."

The FDA accelerated approval of IMDELLTRA is based on results from the Phase 2 DeLLphi-301 clinical trial that evaluated IMDELLTRA in patients with SCLC who had failed two or more prior lines of treatment, and who had received the 10 mg every two weeks dosing (Q2W) regimen. Results from the study found that IMDELLTRA at the 10 mg Q2W dose (N=99) demonstrated a robust objective response rate (ORR) of 40% (95% Confidence Interval [CI]: 31, 51) and median DoR of 9.7 months (CI: 2.7, 20.7+). The median overall survival (mOS) was 14.3 months, with final and complete survival data yet to mature.3

The IMDELLTRA label includes a Boxed Warning for cytokine release syndrome (CRS) and neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), in addition to warnings and precautions for cytopenias, infections, hepatotoxicity, hypersensitivity, and embryo-fetal toxicity. The most common (> 20%) adverse reactions reported among patients were CRS (55%), fatigue (51%), pyrexia (36%), dysgeusia (36%), decreased appetite (34%), musculoskeletal pain (30%), constipation (30%), anemia (27%), and nausea (22%). Permanent discontinuations due to treatment-emergent adverse events (TEAEs) were infrequent (7%). CRS was largely confined to the first and second dose, predominantly grade 1 or 2, and was generally managed with supportive care. Details of the Important Safety Information are included below.

Amgen's Commitment to Patient Support
Amgen is committed to supporting patients with ES-SCLC and to helping ensure appropriate patients with access to IMDELLTRA. Patients, caregivers, and physicians who need support, tools, or resources can contact Amgen® SupportPlus. Amgen also provides patient assistance for its medicines marketed in the U.S. in a variety of ways, including for uninsured or under-insured patients through the Amgen Safety Net Foundation, a nonprofit patient assistance program sponsored by Amgen that helps qualifying patients access Amgen medicines at no cost.

About IMDELLTRA™ (tarlatamab-dlle)
IIMDELLTRA is a first-in-class immunotherapy engineered by Amgen researchers that binds to both DLL3 on tumor cells and CD3 on T cells, activating T cells to kill DLL3-expressing SCLC cells. This results in the formation of a cytolytic synapse with lysis of the cancer cell.2,4 DLL3 is a protein that is expressed on the surface of SCLC cells in ~85-96% of patients with SCLC, but is minimally expressed on healthy cells, making it an exciting target.3,5

IMDELLTRA™ (tarlatamab-dlle) U.S. Indication
IMDELLTRA™ (tarlatamab-dlle) is indicated for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) with disease progression on or after platinum-based chemotherapy.

This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

TCRX: TScan Therapeutics Announces First Patient Dosed in Phase 1 Clinical Trial Evaluating TCR-T Therapy for the Treatment of Solid Tumors

https://finance.yahoo.com/news/tscan-therapeutics-announces-first-patient-110000594.html

TScan Therapeutics, Inc.
Patient dosed with TSC-203-A0201 targeting cancer-associated antigen PRAME

On-track to report initial data from the solid tumor clinical trial in 2024

WALTHAM, Mass., May 09, 2024 (GLOBE NEWSWIRE) -- TScan Therapeutics, Inc. (Nasdaq: TCRX), a clinical-stage biopharmaceutical company focused on the development of T cell receptor (TCR)-engineered T cell (TCR-T) therapies for the treatment of patients with cancer, today announced that the first patient has been dosed in the Company’s Phase 1 trial evaluating TCR-T therapy for the treatment of solid tumors. The patient, diagnosed with metastatic melanoma, was dosed with TSC-203-A0201 targeting the cancer-associated antigen PReferentially expressed Antigen in MElanoma (PRAME).

“Dosing the first patient in our solid tumor program is a significant milestone for us, as we are now well underway with both of our core clinical programs,” said Gavin MacBeath, Ph.D., Chief Executive Officer. “There is a lot of enthusiasm for this trial, and we are already manufacturing TCR-T products for three more patients. We have six TCR-Ts cleared under existing IND applications for patient dosing in this program, and we plan to file additional IND applications to further expand the ImmunoBank across diverse targets and HLA types to broaden the reach of multiplex TCR-T therapy for solid tumors.”

“Solid tumors are notoriously heterogeneous, and we believe that an effective way to treat solid tumors is through a multi-pronged approach,” added Chrystal U. Louis, M.D., Chief Medical Officer. “Customized multiplex TCR-T therapy is designed to achieve durable responses by overcoming tumor heterogeneity and resistance that develops from either target or HLA loss. We look forward to sharing initial data from our solid tumor trial later this year.”

About TScan’s Solid Tumor Program

TScan’s Phase 1 clinical trial is designed to assess the safety and feasibility of T-Plex, autologous customized TCR-T therapy targeting multiple peptide/human leukocyte antigens (HLA) targets in participants with antigen-positive, locally advanced, unresectable or metastatic solid tumors. Multiplex TCR-T therapy has the potential to overcome tumor heterogeneity and HLA loss of heterozygosity, commonly observed resistance mechanisms in solid tumors. First generation TCR-T therapies, targeting single antigens, have shown encouraging response rates in patients, but have often shown limited duration of response.

TScan believes that its approach of dosing patients with more than one TCR-T targeting different cancer-associated antigens will result in increased response rates and increased duration of response. To make this possible, TScan is screening patients (screening protocol: NCT05812027) with melanoma, non-small cell lung cancer (NSCLC), head and neck cancer, cervical cancer, ovarian cancer, anogenital cancers, and other solid tumors for target expression and the presence of intact HLA genes in their tumor cells. Eligible patients are then enrolled in the study treatment protocol (NCT05973487) and administered one or more investigational TCR-T products that are matched to cancer-associated antigens expressed in their tumors. This is made possible by the Company’s ImmunoBank, its repository of therapeutic TCRs that recognize diverse targets and are associated with multiple HLA types. Currently, the ImmunoBank includes six TCR-T clinical candidates in Phase 1 development: TSC-203-A0201 (PRAME, HLA-A*02:01); TSC-200-A0201 (HPV16, HLA-A*02:01); TSC-201-B0702 (MAGE-C2, HLA-B*07:02); TSC-204-A0201 (MAGE-A1, HLA-A*02:01); TSC-204-C0702 (MAGE-A1, HLA-C*07:02); and TSC-204-A0101 (MAGE-A1, HLA-A*01:01). TScan intends to continue to expand the ImmunoBank with TCR-Ts for additional targets and HLA types, thereby increasing the number of patients that are eligible to receive multiplex therapy.

“We continue to make meaningful progress across both our solid tumor and heme malignancies Phase 1 clinical programs. As we rapidly approach dosing the first patients in the solid tumor program, I am pleased to share that over 40 patients have completed all biomarker testing in the screening protocol, with the majority qualifying for at least one TCR-T in our ImmunoBank and many qualifying for multiplex therapy. This should allow for rapid enrollment into the treatment protocol over the course of the year,” said Gavin MacBeath, Ph.D., Chief Executive Officer. “With respect to the heme program, we are encouraged to see continued positive data with all treatment-arm patients remaining relapse-free with no detectable cancer to date, now with a median follow-up of over 10 months.”

Solid Tumor Program: TScan continues to expand the ImmunoBank, a collection of therapeutic TCR-Ts that target different cancer-associated antigens presented on diverse HLA types. TScan’s strategy is to treat patients with multiple TCR-Ts to overcome tumor heterogeneity and prevent resistance that may arise from either target or HLA loss (screening protocol: NCT05812027; treatment protocol: NCT05973487).

Phase 1 solid tumor clinical study has been initiated; first three patients expected to be dosed in early May 2024.

More than 40 patients have completed all biomarker testing in the screening protocol across a broad array of tumor types. 60% of patients qualify for at least one TCR-T in the ImmunoBank and approximately 30% are eligible for multiplex therapy (T-Plex), potentially enabling rapid enrollment into the treatment protocol upon disease progression.

Patients have been identified across all six TCR-T cohorts with dosing expected to commence early May.

Initial data on patients from both singleplex and multiplex cohorts expected in the second half of 2024.

Additional IND filings planned to continue to expand the ImmunoBank.

Long-term duration of response data for multiplex therapy anticipated in 2025.

Heme Malignancies Program: TScan’s two lead TCR-T cell therapy candidates, TSC-100 and TSC-101, are designed to treat residual disease and prevent relapse in patients with acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), or myelodysplastic syndromes (MDS) undergoing allogeneic hematopoietic cell transplantation (HCT) (NCT05473910).

All eight patients treated with TSC-100 or TSC-101 remain MRD negative, relapse-free with no detectable cancer to date in either bone marrow biopsies or peripheral blood (median follow-up of >10 months) and no dose limiting toxicities observed to date.

To date, all but one patient has exhibited complete donor chimerism in all subsets of blood cells at all time-points, indicating that only donor-derived cells are present in these patients following treatment with either TSC-100 or TSC-101. One patient with T-ALL who was treated with TSC-100 at the lowest dose level exhibited minimally detectable (<0.3%) mixed donor chimerism at 10.5 months and 12 months post-transplant.

No detectable mixed chimerism was observed in the malignant cell lineage (CD3+ T-cells) for this patient; mixed chimerism was only observed in healthy nonmalignant blood cells (CD33+ myeloid cells)

In contrast, for the control arm (transplant alone), eight patients have now been enrolled and only one has achieved and maintained complete donor chimerism to date. Two patients relapsed approximate six months post-transplant and one of these patients died approximately three months later. A third patient required clinical intervention on day 133 because of concerns of impending relapse, and a fourth died 21 days post-transplant.

Opening of expansion cohorts at the recommended Phase 2 dose level to further characterize safety and evaluate translational and efficacy endpoints is planned for the third quarter of 2024.

Completion of Phase 1 enrollment and reporting of one-year clinical and translational data on initial patients is anticipated in the second half of 2024.

Expects to initiate registration trial pending feedback from regulatory authorities and report two-year relapse data in 2025.
