NexCAR19™ (Talicabtagene autoleucel) - Approved Indications

INN & Regulatory Reference

International Non-proprietary Name (INN): Talicabtagene autoleucel (NexCAR19™)   |   DCGI Approved |   Approval Date: 2023   |   Manufacturer: ImmunoACT, Navi Mumbai

B-NHL

Relapsed/Refractory B-cell Non-Hodgkin Lymphoma (R/R B-NHL)

After 1 or more lines of prior systemic therapy  ·  Age 15 years and above

  • ✓ Diffuse Large B-cell Lymphoma (DLBCL)
  • ✓ Primary Mediastinal B-cell Lymphoma (PMBCL)
  • ✓ Follicular Lymphoma (FL)
  • ✓ Mantle Cell Lymphoma (MCL)
  • ✓ Marginal Zone Lymphoma (MZL)
  • ✓ High-Grade B-cell Lymphoma (HGBL)
Epidemiology Context

~40% of DLBCL patients relapse after first-line therapy; >60% are ineligible for autologous stem cell transplantation (ASCT), representing a significant unmet need addressed by NexCAR19™.

B-ALL

Relapsed/Refractory B-cell Acute Lymphoblastic Leukemia (R/R B-ALL)

After 1 or more lines of prior therapy  ·  Age 15 years and above

  • ✓ CD19-positive B-cell precursor ALL confirmed by flow cytometry or immunohistochemistry
  • ✓ Relapsed or refractory after ≥1 prior line of therapy, including one intensive chemotherapy regimen
  • ✓ Applicable to adolescents (age 15–18) and adults - broadening access vs. paediatric-only CAR-T therapies
  • ✓ No active CNS involvement at time of treatment (CNS-1 or CNS-2 only after clearance)
Epidemiology Context

Historical B-ALL survival after relapse remains poor at ~41% with conventional chemotherapy. NexCAR19™ provides a curative-intent option where allogeneic SCT may not be feasible or accessible.

NexCAR19™ was assessed in an open-label, multicentre, phase 1/2 study in six tertiary cancer centres across India. Of 64 patients aged 15 and above with either relapsed/refractor B-cell lymphoma or B-cell acute lymphoblastic leukaemia, 14 were enrolled in Phase 1, and 50 were enrolled in Phase 2. At an efficacy dose of at least 5 × 10⁶ CAR T cells per kg of body weight, NexCAR19 demonstrated an overall response rate of 73%. The trial exhibited a manageable safety profile with high efficacy in a difficult-to-treat population with B-cell malignancies, with these results published in Lancet Haematology

How does NexCAR19™ work - Scientific Profile

A humanized CD19-targeting CAR-T construct with optimized persistence and reduced immunogenicity

  1. Humanized scFv — CD19 TargetingA humanized single-chain variable fragment (scFv) antibody specifically targets CD19 markers on B-cells. Humanized design significantly reduces immunogenicity compared to murine-based CAR constructs.
  2. Optimized Flexible Spacer (CD8 Hinge)An optimized flexible spacer enhances target binding efficiency and allows optimal orientation of the scFv for CD19 engagement.
  3. 4-1BB Co-stimulatory DomainSpecialized 4-1BB co-stimulatory signaling significantly boosts T-cell activation and promotes long-term T-cell persistence — contributing to durability of response beyond 24 months in select patients.
  4. CD3ζ Signaling DomainCD3ζ signaling components trigger potent T-cell immune response upon CD19 binding, initiating cytotoxic killing of CD19+ malignant B-cells.

Proven Clinical Performance

Our anti-CD19 binding technology has demonstrated remarkable persistence in clinical settings, with documented durability of action extending beyond 24 months in select patients. The humanized ScFv component delivers exceptional efficacy while contributing to a reduced incidence of severe treatment-related toxicities.

Superior Therapeutic Profile

NexCAR19™ modified T-cells offer a comprehensive treatment solution:

  • Safety: Rigorously tested cellular product with established safety profile
  • Durability: Long-lasting anti-cancer activity for sustained disease control
  • Effectiveness: Consistent response rates across diverse patient populations

Optimized Dosing Strategy

With an efficacy threshold of more than 5 million CAR-T cells per kilogram of body weight, NexCAR19™ achieves exceptional tumor penetration and maintains effectiveness even in challenging high-risk patient populations.

NexCAR19™ is a type of CAR-T cell therapy. T-cells are naturally made by your body as an advanced defense against viruses and cancer cells. As they mature, they develop specific connectors (receptors) to target key signals in cancer cells. However, cancers can escape the inbuilt defense mechanism of T-cells, which can lead to an increase in tumor burden and can result in the survival of cancer cells and a further increase in tumor burden. CD19 is a protein commonly present on the surfaces of certain B-cell cancers.

Our scientists have designed instructions for your T-cells to express unique proteins called Chimeric Antigen Receptors (CARs) on their surface, which will enable them to bind to a specific target on the cancer cells. These instructions are delivered genetically using a vehicle known as a lentiviral vector.NexCAR19 targets a marker called CD19, which is commonly present on the surface of cancerous B-cells.

Smarter CAR-Construct & Design for Safer Treatment

At the heart of ImmunoACT’s innovation is a next-generation cell and gene therapy platform, purpose-built to deliver affordable efficacy without compromising safety. Our approach blends cutting-edge science with thoughtful design to make these therapies more accessible and tolerable. 

Our CAR-T constructs use fully humanized components, making them more “familiar” to the immune system. This reduces the risk of rejection, minimizes off-target toxicity, and improves patient experience by lowering the need for intensive supportive care.

Each CAR we design includes:

  • A single-chain variable fragment (scFv) tailored for precise tumor targeting
  • A flexible hinge (spacer) to enable optimal antigen engagement
  • A CD8α transmembrane domain for enhanced stability
  • A 4-1BB co-stimulatory domain to support T-cell survival and sustained action
  • A CD3ζ signaling domain to trigger strong and specific immune responses

Our CAR-T therapies integrate humanized sequences and undergo rigorous optimization to ensure potency, persistence, and safety. By reducing the likelihood of severe toxicities, we are not just improving patient safety, we are redefining how cell therapies can be delivered.

The gene sequence of the CAR construct is first integrated into a plasmid, which is then used to produce a lentiviral vector. This vector delivers the CAR gene into T cells, enabling them to recognize and attack cancer cells.

NexCAR19™ Manufacturing Process

1. Leukapheresis

Peripheral Blood Mononuclear Cells (PBMCs) are collected from the patient using leukapheresis.
This forms the foundational starting material for autologous CAR-T cell manufacturing.

2. Monocyte Depletion

Monocytes are removed from the PBMC population to reduce non-T-cell components.
This enhances T-cell purity and improves the efficiency of downstream processes.

3. T-Cell Activation

T-lymphocytes are activated using CD3/CD28 costimulatory signals in a controlled environment. This primes the cells for efficient gene transfer during the transduction step.

4: Lentiviral Transduction

Activated T-cells are genetically modified with a lentiviral vector encoding the anti-CD19 CAR. This step equips T-cells to recognize and attack CD19-expressing tumor cells.

5: CAR-T Cell Production

Following transduction, T-cells begin expressing the chimeric antigen receptor on their surface. These cells are now classified as NexCAR19—genetically reprogrammed to target B-cell malignancies.

6: Expansion to Target Dose

The CAR-T cells are cultured under GMP conditions to reach the therapeutic dose. Cell growth is monitored to maintain viability, potency, and phenotype consistency.

7: Formulation & Cryopreservation

The final CAR-T product is formulated with infusion-ready buffer and cryopreserved. Post quality checks, it is stored under ultra-low temperatures until patient infusion.
