Autolus Therapeutics Announces
Update on its Novel CAR T Cell
Program for Peripheral T Cell
Lymphoma (PTCL)
-First patient dosed in Phase 1/2
trial of AUTO4 in TRBC1-positive peripheral T cell
lymphoma-
-Preclinical data for AUTO5
targeting TRBC2-positive peripheral T cell lymphoma presented at
the 60th Annual American Society of
Hematology (ASH) Meeting-
Autolus Therapeutics plc (Nasdaq: AUTL), a clinical-stage
biopharmaceutical company developing next-generation programmed T
cell therapies for the treatment of cancer, today announced that
the first patient has been dosed in its Phase 1/2 LibrA T1 clinical
trial of AUTO4, a developmental therapy for the treatment of
relapsed or refractory TRBC1-positive peripheral T cell lymphoma
(PTCL). In addition, the company also announced that data on the
preclinical sister program, AUTO5 targeting TRBC2-positive
lymphoma, were presented at the 60th American Society of Hematology
(ASH) Annual Meeting, San Diego.
Autolus' T cell program comprises a companion diagnostic to
determine whether the PTCL is TRBC1- or TRBC2-positive and two
novel CAR T cell product candidates AUTO4 and AUTO5. PTCL is a rare
and heterogeneous form of non-Hodgkin lymphoma, currently estimated
to affect approximately 2,900 patients in the United States, annually.1
"There are limited treatment options for patients with relapsed
and/or refractory peripheral T cell lymphoma. We are particularly
excited to participate in the LibrA T1 trial of AUTO4, a novel CAR
T cell therapy for this aggressive cancer," said Dr. Kate
Cwynarski, Principal Investigator, Consultant Haematologist at
University College London Hospital and Honorary Senior Lecturer at
University College London.
"Effective systemic treatment for peripheral T cell lymphomas
remains a challenge. CAR T therapies selectively targeting
TRBC1-positive and TRBC2-positive T cell lymphomas have the
potential to be major therapeutic advances," said Steven T. Rosen, M.D. provost and chief
scientific officer of City of Hope and director of the Beckerman
Research Institute of City of Hope."
On December 2 at the 60th ASH
Annual Meeting in San Diego, the
company presented data from preclinical studies of AUTO5 targeting
TRBC2. TRBC1 and TRBC2 are virtually identical in sequence, and
antibody binders had to be designed to differentiate TRBC1 from
TRBC2 extracellular domains by selectively recognizing a single
inversion of two amino acids. Employing a structural biology
approach and molecular modelling techniques, a binder was generated
that could bind TRBC2 without binding to TRBC1, and when included
in a CAR T approach, selectively eliminated TRBC2-positive
cells.

Antigen Receptors for the complete treatment of T cell lymphomas

About LibrA T1 P1/2 Clinical
Trial
The LibrA T1 trial is a single-arm, open label, multi-center,
Phase 1/2 trial evaluating the safety and efficacy of AUTO4, a
single dose intravenous CAR T cell treatment targeting TRBC1 in
patients with relapsed or refractory TRBC1-positive selected PTCL.
The trial will consist of a Phase 1 portion, or dose escalation
phase, and a Phase 2 portion, or expansion phase. The Phase 1
portion of the trial, which is expected to enroll up to 25
patients, is designed to evaluate up to three dose levels,
beginning with a low dose of 25 million AUTO4 cells in cohorts of
three to six patients. If no dose limiting toxicities are observed,
the dose escalation phase of the trial will continue to higher
doses of 75 million AUTO4 cells and 225 million AUTO4 cells. Once a
recommended dose has been identified in the Phase 1 portion of the
trial, up to 30 patients will be enrolled and treated in the Phase
2 portion.
About AUTO4 and AUTO5
AUTO4 is a programmed T cell therapy product candidate being
developed to leverage a new targeting approach based on the
mutually exclusive expression of two subtypes of the T cell
receptor beta chain: AUTO4 targets TRBC1, while another of the
company's product candidates in development, AUTO5, targets TRBC2.
Normal T cells contain both TRBC1 and TRBC2 compartments, whereas T
cell lymphoma cells are derived from mature cells and express only
TRBC1 or TRBC2. A companion diagnostic is used to identify if the T
cell lymphoma is TRBC1 or TRBC2 positive. Unlike non-selective
approaches targeting the entire T cell population that can lead to
severe immunosuppression, this approach has the potential to
eradicate a portion of T cells containing the malignancy, while
preserving a healthy T cell sub-population to preserve cellular
immunity.

criteria, visit www.clinicaltrials.gov.
About Peripheral T Cell Lymphoma
(PTCL)
Lymphoma is the most commonly occurring blood cancer. The two
main forms of lymphoma are Hodgkin lymphoma (HL) and non-Hodgkin
lymphoma (NHL). Lymphoma occurs when cells of the immune system
called lymphocytes, a type of white blood cell, grow and multiply
uncontrollably. Lymphomas can originate from two types of
lymphocytes, B cells and T cells. T cell lymphoma is a rare and
heterogeneous form of NHL, representing approximately 10 to 20% of
NHL cases and 3 to 4% of all hematological malignancies
While T cell lymphoma is a smaller percentage of all lymphomas
compared to B cell lymphomas, T cell lymphoma is an aggressive
disease. Most T cell lymphomas are PTCL, and generally involve
high-grade tumors, with a relatively high proportion of patients
rapidly developing significant morbidity. The five-year survival
rate ranges from 18% to 24%. The first-line treatment for PTCL
consists of the combination chemotherapy CHOP, consisting of
cyclophosphamide, vincristine, doxorubicin and prednisolone.
However, treatment with chemotherapy introduces toxicity concerns,
including low blood cell counts, nausea, vomiting, diarrhea, hair
loss, mouth sores, and increased risk of infections. Additionally,
with CHOP chemotherapy, complete response rates are lower than in
DLBCL and relapse is more common. In many treatment centers, CHOP
chemotherapy is consolidated with high-dose chemotherapy and
autologous or allogenic stem cell transplantation. According to
National Comprehensive Cancer Network (NCCN) guidelines,
participation in a clinical trial is the preferred option for all
patients with T cell lymphoma with any stage
disease.2
