Fully Outpatient CAR-T: What Physicians Should Know About This New Option

Chimeric Antigen Receptor T-cell therapy, commonly called CAR-T therapy, represents one of the most important advances in cancer immunotherapy for patients with relapsed or refractory B-cell lymphomas. While its use is expanding nationwide, access to this highly specialized cellular therapy remains limited in many regions.

Mary Bird Perkins Cancer Center (MBP) is helping close that gap by offering the region’s first fully outpatient CAR-T program, making this advanced therapy more accessible for patients in and around
Baton Rouge.

Andrew Dalovisio, MDLed by Dr. Andrew Dalovisio, the program allows eligible patients to receive CAR-T therapy while remaining near home, improving comfort and quality of life while maintaining close clinical monitoring.

“CAR-T has fundamentally changed how we think about treating aggressive B-cell malignancies,” said Dr. Dalovisio, Director of the Lymphoma, Myeloma, and Cellular Therapy program at MBP. “For the right patient, it offers a targeted and potentially durable option when other therapies have failed.”

What to know about CAR-T

CAR-T therapy is a personalized cellular treatment that uses a patient’s own immune system to target cancer. The process involves several steps:

  • Leukapheresis: T cells are collected from the patient’s blood.
  • Genetic modification: In a controlled laboratory setting, the cells are engineered to express a chimeric antigen receptor (CAR) that recognizes a specific protein, most often CD19, on B-cell lymphoma cells.
  • Cell expansion: The modified T cells are multiplied to reach therapeutic levels.
  • Reinfusion: After brief lymphodepleting chemotherapy, the CAR-T product is infused back into the patient, where it seeks out and destroys malignant B cells.

Because CAR-T uses autologous immune cells, it is distinct from chemotherapy, monoclonal antibodies, or stem cell transplantation and offers a highly targeted mechanism of action.

Current FDA-Approved Indications for CAR-T Therapy

CAR-T therapy is currently FDA-approved for several hematologic malignancies. MBP can evaluate patients with:

  • Chronic lymphocytic leukemia / small lymphocytic lymphoma (CLL/SLL)
  • Mantle cell lymphoma (MCL)
  • B-cell acute lymphoblastic leukemia (B-ALL)
  • Multiple myeloma (MM)
  • Diffuse large B-cell lymphoma (DLBCL)
  • Marginal zone lymphoma (MZL)
  • Primary central nervous system lymphoma (PCNSL)
  • Follicular lymphoma (FL)

This broad spectrum ensures that referring physicians treating these diagnoses know their patients may be eligible for evaluation.

Using CAR-T After Other Therapies Fail

CAR-T therapy is especially valuable for patients whose disease has not responded to conventional treatments. Its benefits include:

  • Activity against chemotherapy-resistant disease
  • Effectiveness in heavily pretreated patients
  • Potential for long-term remission in select cases

For CAR-T to be most effective, early referral is critical. “We often see patients only after all options have been exhausted,” Dr. Dalovisio explained. “At that point, disease burden or performance status may limit eligibility. Early consultation allows us to assess candidacy sooner and improve the chance of successful treatment.”

Referring physicians play a key role in identifying patients with early relapse or primary refractory disease who may benefit from timely evaluation.

Fully Outpatient CAR-T at MBP

One of the most distinctive features of MBP’s program is its ability to deliver CAR-T therapy entirely in the outpatient setting. This model offers several advantages:

  • Reduced inpatient hospitalization
  • Greater patient comfort at home
  • Increased access for patients traveling from outside the region
  • Close monitoring supported by a specialized cellular therapy team

This approach is supported by MBP’s coordinated infrastructure, including infusion services, patient navigators, and streamlined communication with referring providers.

Updated FDA REMS Requirements and Access

Recent updates to the FDA’s Risk Evaluation and Mitigation Strategy (REMS) requirements have further expanded access to outpatient CAR-T. The required post-infusion monitoring period has been reduced from 30 days to 14 days, decreasing geographic and logistical barriers.

Caregiver Support and Safety

Outpatient CAR-T requires a reliable support system to ensure safety during the monitoring period. Each patient must have a designated caregiver who can:

  • Watch for early signs of cytokine release syndrome (CRS) or neurotoxicity
  • Communicate promptly with the care team
  • Assist with transportation and daily needs

MBP supports patients and caregivers through education, symptom-reporting protocols, patient navigation services, and 24/7 clinical access. This structured approach allows CAR-T to be delivered safely without routine inpatient admission.

Ongoing Collaboration With Referring Physicians

MBP’s CAR-T program is built on partnership with referring providers. Physicians receive:

  • Ongoing communication during evaluation, infusion, and monitoring
  • Clear updates on patient status and complications
  • A defined transition back to their care after CAR-T treatment

“Our role is to complement the referring physician’s long-term relationship with the patient,” said Dr. Dalovisio. “We focus on delivering CAR-T therapy and then return the patient to their primary oncology team for continued management.”

The Importance of Early Referral

Early referral does not require certainty that a patient will proceed to CAR-T therapy. Consultation is encouraged when:

  • Disease is primary refractory
  • Relapse occurs early after initial therapy
  • Second-line therapy has failed
  • Performance status remains adequate

Early collaboration allows the MBP team to assess eligibility, plan timing, and coordinate care while the patient is still an appropriate candidate.
