CAMBRIDGE, Mass.–(BUSINESS WIRE)–Magenta Therapeutics (NASDAQ: MGTA), a clinical-stage biotechnology
company developing novel medicines to bring the curative power of stem
cell transplant to more patients, today reported financial results for
the first quarter ended March 31, 2019 and recent business highlights.

“In 2019 we are continuing to advance our portfolio of programs toward
our vision of curing more patients with autoimmune diseases, blood
cancers and genetic diseases. This momentum was reflected in the recent
start of our Phase 1 study of MGTA-145, our first-line therapy for stem
cell mobilization and second clinical program, as well as in the
extended evidence of disease benefit we see in our Phase 2 study of our
MGTA-456 cell therapy in patients with inherited metabolic disorders,”
said Jason Gardner, D.Phil., Chief Executive Officer and President,
Magenta Therapeutics. “We are positioned to build on this momentum
through additional important milestones across each of our programs and
to deliver value for patients and shareholders.”

Upcoming Anticipated Milestones:

The Company plans to achieve the following key milestones in 2019:

  • Present preclinical data on C100 anti-CD45 targeted conditioning
    program in autoimmune disease and declare a development candidate
  • Present preclinical data on C200 anti-CD117 targeted conditioning
    program in gene therapy
  • Present clinical data from the Phase 1 study of MGTA-145
  • Present additional clinical data from the Phase 2 study of MGTA-456 in
    inherited metabolic disorders (IMDs)

Recent Business Highlights:

Dosed first subjects in Phase 1 clinical trial of MGTA-145 first-line
stem cell mobilization product candidate:
In April 2019, Magenta
announced that it had dosed the first subjects in a Phase 1 study of
MGTA-145. Magenta intends to develop MGTA-145 in autoimmune diseases,
blood cancers and genetic diseases. The Phase 1 study will investigate
the safety and tolerability of MGTA-145 alone and in combination with
plerixafor in healthy volunteers and establish recommended Phase 2
doses. The study will also measure the number of hematopoietic stem
cells in the blood after dosing with MGTA-145 alone and in combination
with plerixafor. Magenta expects to present data from the study in the
second half of 2019. Depending on the Phase 1 data, the Company plans to
move MGTA-145 into a Phase 2 study in multiple myeloma and non-Hodgkin
lymphoma in 2020.

Updated clinical data for MGTA-456 cell therapy showed continued
signs of durable clinical benefit in patients with IMDs:
Magenta
presented updated data from the Phase 2 clinical study of MGTA-456 in
patients with IMDs at the American Academy of Neurology (AAN) annual
meeting in May 2019. Patients with cerebral adrenoleukodystrophy (cALD)
treated with MGTA-456 in the study showed stable neurological function
scores and persistent resolution of brain inflammation by MRI at 6
months post-transplant, suggesting that the progression of disease has
been halted. Magenta expects to update these results in the second half
of 2019.

Preclinical data on E478 stem cell gene therapy expansion program
show significant increase in gene-modified stem cells:
At the
American Society of Gene and Cell Therapy annual meeting in May 2019,
Magenta presented data showing that E478 increased the number of human
hematopoietic stem cells modified with either CRISPR/Cas9 or lentiviral
vector by 10-fold compared to standard culture methods. Magenta is
developing E478 to achieve high doses of gene-modified stem cells for
better outcomes in patients with genetic disorders, including sickle
cell disease and beta-thalassemia, where gene editing or viral vector
technologies are used to correct stem cells. Magenta intends to develop
E478 in partnership with gene therapy companies.

Presented nine abstracts at Transplant and Cellular Therapies
Conference:
Magenta presented data covering the breadth of the
Company’s integrated portfolio of programs at the Transplant and
Cellular Therapy (TCT) annual meeting in February 2019.

Financial Results:

Cash Position: Cash, cash equivalents and marketable securities
as of March 31, 2019, were $127.3 million compared to $142.6 million on
December 31, 2018. In addition, earlier this week Magenta announced that
it completed a public offering of common stock and raised gross proceeds
of $64.8 million. Magenta anticipates that its cash, cash equivalents
and marketable securities, including the proceeds from this recent
financing, will be sufficient to fund operations and capital
expenditures into the second half of 2021.

Research and Development Expenses: Research and development (R&D)
expenses were $10.5 million in the first quarter of 2019, compared to
$7.8 million in the first quarter of 2018. The increase was driven by
investments related to the IND filing and clinical activities for
MGTA-145, as well as the on-going clinical development of MGTA-456.

General and Administrative Expenses: General and administrative
(G&A) expenses were $5.8 million for the first quarter of 2019, compared
to $3.5 million for the first quarter in 2018. The increase was
primarily due to increased personnel and facility costs associated with
the growth of the Company.

Net Loss: Net loss was $14.8 million for the first quarter of
2019, compared to net loss of $11.2 million for the first quarter of
2018.
