"Patients with follicular lymphoma who do not respond to their current treatment or who relapse early after treatment often have to endure multiple treatments, which can result in diminished clinical outcomes with each successive therapy," said Stephen J. Schuster, MD, the Robert and Margarita Louis-Dreyfus Professor in Chronic Lymphocytic Leukemia and Lymphoma Clinical Care and Research in Penn’s Perelman School of Medicine and director of the Lymphoma Program at the Abramson Cancer Center. Schuster will present the results at ASCO (Free ASCO Whitepaper). "Our goal as researchers is to continue to explore the potential of CAR-T therapy, and the robust ELARA safety and efficacy findings suggest Kymriah may play an important role in the third-line treatment of relapsed or refractory follicular lymphoma."
In the primary ELARA analysis, 97 patients were infused and evaluated for safety, 94 patients were evaluable for efficacy with a median follow-up of 11 months. Importantly, no patients experienced grade 3/4 cytokine release syndrome (CRS), the most common side effect associated with CAR-T therapy. Grade 1 or 2 CRS, as defined by the Lee Scale, occurred in 49% of patients. Grade 1 or 2 neurological events (NEs) (per CTCAE v4.03) occurred in 9% of patients and one patient experienced grade 4 NEs and recovered. Sixty-five percent of patients experienced grade ≥3 adverse events within 8 weeks post-infusion, most commonly neutropenia (28%) and anemia (13%). Three patients died from progressive disease and no deaths were treatment related. Kymriah was administered in the outpatient setting for 18% of patients in the ELARA trial1,3.
Kymriah led to responses for the majority of patients treated, with 66% achieving a complete response (CR) (95% CI, 56-75). The overall response rate was 86% (95% CI, 78-92). Response rates were consistent across high-risk patient subgroups. The median duration of response (DOR) in all responders (95% CI, NE-NE), progression free survival (PFS) (95% CI, 12.1-NE), and overall survival (OS) (95% CI, NE-NE) were not reached. Estimated DOR in patients with CR and PFS rates at six months were 94% (95% CI, 82-98) and 76% (95% CI, 65-84), respectively. Efficacy findings include data from nearly twice as many patients as were reported at the interim analysis, including high-risk and heavily pretreated patients who continued to relapse or have refractory disease despite exposure to numerous prior lines of therapy. The median number of prior therapies was 4 (range, 2-13), 78% of patients were refractory to their last treatment (76% to ≥2 prior regimens) and 60% progressed within 2 years of initial anti-CD20-containing treatment1,3.
"The strength of these pivotal results from the ELARA trial underscore the promising potential of Kymriah in the treatment of patients with relapsed or refractory follicular lymphoma," said Stefan Hendriks, Global Head Cell & Gene, Novartis Oncology. "With deep experience in CAR-T cell therapy and the largest global manufacturing footprint, Novartis is boldly committed to bringing the benefits of Kymriah to more patients with advanced blood cancers, and we look forward to advancing global regulatory submissions in this indication as quickly as possible."

About Follicular Lymphoma
Follicular lymphoma (FL), the second most common form of non-Hodgkin lymphoma (NHL), is an indolent lymphoma, and represents approximately 22% of NHL cases2,4. Despite new treatments that improve overall survival, FL is regarded as an incurable malignancy with a relapsing and remitting pattern5,6. Throughout the lifetime of a patient with relapsing FL, they may be exposed to a median of five lines of prior treatment, with an upper range of 12 lines7,8. Although patients in third or later line treatment for FL have multiple systemic therapies available, the efficacy of these regimens drops off rapidly in later lines2. Additionally, because of this relapsing and remitting pattern, patients who are refractory to treatment or quickly relapse may exhaust available treatment options6.
About the ELARA trial
ELARA is a Phase II, single-arm, multicenter, open-label trial investigating the efficacy and safety of Kymriah in adult patients with r/r FL. This international trial has enrolled patients from over 30 sites in 12 countries worldwide. The primary endpoint is CRR based on best response by central review (Lugano 2014 criteria). Patients evaluable for efficacy had measurable disease at infusion and more than six months of follow-up from infusion or discontinued early. After infusion, disease assessments were performed every three months. Secondary endpoints include overall response rate, duration of response, progression-free survival, overall survival and safety.
In Q2 2020, the FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to Kymriah in r/r FL, based on preliminary results from the ELARA trial. RMAT designation is intended to expedite the development and review of Kymriah as a regenerative therapy for this underserved patient population. Kymriah also has Orphan Drug designation from the FDA for this disease.
About Kymriah
Kymriah is the first-ever FDA-approved CAR-T cell therapy, and the first-ever CAR-T to be approved in two distinct indications. It is a one-time treatment designed to empower patients’ immune systems to fight their cancer. Kymriah is currently approved for the treatment of r/r pediatric and young adult (up to and including 25 years of age) acute lymphoblastic leukemia (ALL), and r/r adult diffuse large B-cell lymphoma (DLBCL)9.

Kymriah (tisagenlecleucel) US Important Safety Information
Kymriah may cause side effects that are severe or life-threatening, such as Cytokine Release Syndrome (CRS) or Neurological Toxicities. Patients with CRS may experience symptoms including difficulty breathing, fever (100.4°F/38°C or higher), chills/shaking chills, severe nausea, vomiting and diarrhea, severe muscle or joint pain, very low blood pressure, or dizziness/lightheadedness. Patients may be admitted to the hospital for CRS and treated with other medications.
Patients with neurological toxicities may experience symptoms such as altered or decreased consciousness, headaches, delirium, confusion, agitation, anxiety, seizures, difficulty speaking and understanding, or loss of balance. Patients should be advised to call their healthcare provider or get emergency help right away if they experience any of these signs and symptoms of CRS or neurological toxicities.
Because of the risk of CRS and neurological toxicities, Kymriah is only available through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called Kymriah REMS.
Serious allergic reactions, including anaphylaxis, may occur after Kymriah infusion. Kymriah can increase the risk of life-threatening infections that may lead to death. Patients should be advised to tell their healthcare provider right away if they develop fever, chills, or any signs or symptoms of an infection.
Patients may experience prolonged low blood cell counts (cytopenia), where one or more types of blood cells (red blood cells, white blood cells, or platelets) are decreased. The patient’s healthcare provider will do blood tests to check all of their blood cell counts after treatment with Kymriah. Patients should be advised to tell their healthcare provider right away if they get a fever, are feeling tired, or have bruising or bleeding.
Patients may experience hypogammaglobulinemia, a condition in which the level of immunoglobulins (antibodies) in the blood is low and the risk of infection is increased. It is expected that patients may develop hypogammaglobulinemia with Kymriah and may need to receive immunoglobulin replacement for an indefinite amount of time following treatment with Kymriah. Patients should tell their healthcare provider about their treatment with Kymriah before receiving a live virus vaccine.
After treatment with Kymriah, patients will be monitored lifelong by their healthcare provider, as they may develop secondary cancers or recurrence of their cancer.
Patients should not drive, operate heavy machinery, or do other dangerous activities for eight weeks after receiving Kymriah because the treatment can cause temporary memory and coordination problems, including sleepiness, confusion, weakness, dizziness, and seizures.
Some of the most common side effects of Kymriah are difficulty breathing, fever (100.4°F/38°C or higher), chills/shaking chills, confusion, severe nausea, vomiting and diarrhea, severe muscle or joint pain, very low blood pressure, dizziness/lightheadedness, and headache. However, these are not all of the possible side effects of Kymriah. Patients should talk to their healthcare provider for medical advice about side effects.
Prior to a female patient starting treatment with Kymriah, their healthcare provider may do a pregnancy test. There is no information available for Kymriah use in pregnant or breast-feeding women. Therefore, Kymriah is not recommended for women who are pregnant or breast feeding. Patients should talk to their healthcare provider about birth control and pregnancy.
Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
After receiving Kymriah, patients should be advised that some commercial HIV tests may cause a false-positive test result. Patients should also be advised not to donate blood, organs, or tissues and cells for transplantation after receiving Kymriah.
