OUR AlloCAR T™ PRODUCT PIPELINE TARGETS A VAST ARRAY OF TUMOR TYPES AND AUTOIMMUNE INDICATIONS

Key Features of the Allogene Pipeline The ALPHA3 clinical trial is a key program pivotal Phase 2 study. Designed to be registrational, ALPHA3 is evaluating CD-19-targeting Cemacabtagene ansegedleucel or cema-cel as a one-time, “off-the-shelf” treatment that can be administered immediately upon discovery of minimal residual disease (MRD) following six cycles of R-CHOP or other chemoimmunotherapy, positioning it to become the standard “7th cycle” of frontline treatment available to all eligible patients with diffuse large B-cell lymphoma (DLBCL) and similar types of lymphoma who have MRD. Another study involving hematologic malignancies is an IND-enabling evaluation of CD-70- targeting ALLO-316 for treating CD70+ heme malignancies. In solid tumors, the TRAVERSE trial, a Phase 1 study that has received FTD and RMAT designations, is enrolling ccRCC patients to evaluate CD-70-targeting ALLO-316. Three other solid tumor studies are all IND-enabling. The first of these is evaluating CD-70- targeting ALLO-316 in patients with solid tumors. The second of these is evaluating DLL3- targeting-ALLO-213 in patients with SCLC. The third of these is evaluating Claudin 18.2-targeting ALLO-182 in patients with gastric and pancreatic solid tumors. In autoimmune disease, an IND-enabling, key program study is evaluating CD19/CD70-targeting ALLO-329 in patients with rheumatology disorders. This study is scheduled for IND submission in Q1 2025.

ALPHA3

The pivotal Phase 2 ALPHA3 study takes advantage of cema-cel as a one-time, “off-the-shelf” treatment that can be administered immediately upon discovery of minimal residual disease (MRD) following six cycles of R-CHOP or other chemoimmunotherapy, positioning it to become the standard “7th cycle” of frontline treatment available to all eligible LBCL, inclusive of DLBCL patients with MRD.

ALPHA/ALPHA 2

ASCO 2023 – Allogene presented long-term follow up data from the Phase 1 ALPHA/ALPHA2 trials of ALLO‑501/501A demonstrating for the first time the potential of allogeneic CD19 CAR T to induce durable complete remissions in relapsed/refractory large B-cell lymphoma (r/r LBCL) at a rate similar to approved autologous CD19 CAR T therapies.

TRAVERSE

SITC/IKCS 2024 – We shared new data on ALLO-316, our investigational AlloCAR T™ product candidate for treating CD70-positive advanced or metastatic clear cell renal cell carcinoma (RCC). Results from the Phase 1 TRAVERSE trial highlight the potential of our allogeneic CART therapy to address the unmet needs of adults with CD70-positive RCC who have exhausted standard treatment options.

AACR 2023 – We presented early findings from the Phase 1 TRAVERSE trial evaluating the safety, tolerability, and activity of ALLO-316, an investigational AlloCAR T™ product candidate for the treatment of CD70 positive advanced or metastatic clear cell renal cell carcinoma (RCC).

ALLOGENE’S EXPANDED ACCESS POLICY

“Expanded Access” refers to the use of an investigational product outside of a clinical trial for potential treatment of a serious or life-threatening condition. Allogene Therapeutics is developing allogeneic chimeric antigen receptor T cell (AlloCAR T™) products for patients with blood cancers, solid tumors and autoimmune disease. Consistent with our commitment to bring innovative, safe, and effective products to patients, we are focused on enrolling and conducting the clinical trials necessary to gain regulatory approvals to make our products broadly available as quickly and safely as possible. Participation in one of our clinical trials is the best and preferred route to access these investigational products. Allogene does not currently have any active Expanded Access protocols nor do we currently provide access to our investigational products on an Expanded Access basis. We encourage patients interested in our investigational products to learn more about our ongoing studies by visiting clinicaltrials.gov.

Treating physicians may request information about Allogene’s Expanded Access policy by contacting our clinical trials team:

Allogene will respond to inquiries within 5 business days from receipt.

In the event Allogene decides to consider making one or more of its investigational candidates available for patients who have a serious or life-threatening condition through an Expanded Access program, general criteria to be considered may include: availability of alternative products, the potential risks and benefits to the patient, adequate supply, and potential interference with Allogene’s ongoing clinical trials. All requests would be evaluated on a case-by-case basis in a fair and equitable manner.

This policy shall not serve as a guarantee of access to any specific investigational candidates by any individual patient. Allogene reviews its policies from time to time to ensure conformity with applicable laws and regulations. We reserve the right to revise this policy at any time.
