a press release announcing additional data from the Companys
ongoing Phase 2 company-sponsored trial, which is assessing
single ascending dose safety, pharmacokinetic and
pharmacodynamics of SEL-212 in patients with elevated uric acid

to this Current Report on Form 8-K. In connection with the
issuance of the press release, the Company is holding a public
conference call and webcast on June 15, 2017, at 8:30 a.m. ET,
during which the Company will provide the investor presentation
attached as Exhibit 99.2 to this Current Report on Form 8-K. The
Company undertakes no obligation to update, supplement or amend

Exhibits 99.1 and 99.2 attached hereto) shall not be deemed filed
for purposes of Section 18 of the Securities Exchange Act of 1934
(the Exchange Act), or otherwise subject to the liabilities of
that section, nor shall it be deemed incorporated by reference
into any filing under the Securities Act of 1933, as amended, or
the Exchange Act, except as expressly provided by specific
reference in such a filing.
additional data from the Companys ongoing Phase 2
company-sponsored trial, which is assessing single ascending dose
safety, pharmacokinetic and pharmacodynamics of SEL-212 in
patients with elevated uric acid levels.
generated through June 12, 2017 from the 60 patients currently
enrolled in this open-label, dose ranging Phase 2 trial include:
Mitigated anti-drug antibodies (ADAs) after repeat monthly
administrations of SEL-212>->The prevention of ADAs in a dose-dependent manner resulted in a durable control of serum uric acid (sUA) levels (defined as sUA 6 mg/dl). The clinical data demonstrate a correlation between the prevention of ADAs and the maintenance of pegsiticase activity and serum uric acid control. |
Demonstrated induction of immune tolerance>- A majority
of patients in the minimum effective dose group maintained sUA control following three monthly injections of SEL-212 and two monthly challenge injections of pegsiticase alone. Maintenance of sUA in the challenge portion of the trial provides evidence at this stage that the use of SVP-Rapamycin is enabling immune tolerance, meaning a prevention of ADAs to pegsiticase, which is typically immunogenic when administered alone. |
Reduced rate of gout flares with SEL-212>- In the
control cohorts receiving pegsiticase alone, within the first month of treatment, 50% of patients reported experiencing a gout flare, which is a sudden and severe attack of pain, inflammation and tenderness of the joints. By comparison, only 15% of patients receiving SEL-212 reported a gout flare in the first month of treatment, with reports declining further in subsequent months. These data also appear to be in contrast with the increased incidence of flares reported in clinical trials involving other urate lowering therapies. |
Identified minimum effective dose of SEL-212>- A key
objective of the Phase 2 trial was to determine a minimum effective monthly dose of the two components of SEL-212 (i.e. pegsiticase and SVP-Rapamycin) through an ascending dose matrix design. A majority of the initial patients dosed with 0.4 mg/kg of pegsiticase in combination with 0.08 mg/kg of SVP-Rapamycin maintained sUA control beyond five treatments. As a result, the Company has determined this to be a minimum monthly effective dose of SEL-212. Additional patients are now being added to this cohort, and higher dose levels of SVP-Rapamycin are being tested to further determine the dose regimens that may be taken forward into Phase 3. |
SEL-212 generally well tolerated>- Consistent with the
expected reduction in immunogenicity of pegsiticase when SVP-Rapamycin doses increase, SEL-212 has been generally well tolerated at clinically active doses. There have been a total of eight serious adverse events (SAEs) reported in the trial through June 12, 2017. Seven were infusion reactions, four of which occurred in the cohorts receiving pegsiticase alone or the lowest dose of SVP-Rapamycin and two of which were due to dosing errors. One additional SAE, cholecystitis, was determined to not be related to the study drug. All of the SAEs were successfully treated and resolved without further issues. |
Administration, the Company expects to initiate its Phase 3
program in 2018.

About SELECTA BIOSCIENCES, INC. (NASDAQ:SELB)
Selecta Biosciences, Inc. is a clinical-stage biopharmaceutical company. The Company using its synthetic vaccine particle (SVP) technology to discover and develop targeted therapies that are designed to modulate the immune system to treat rare and serious diseases. The Company is engaged in the research and development of nanoparticle immunomodulatory drugs for the treatment and prevention of human diseases. The Company’s product candidates are in development. The Company’s SVP technology encapsulates an immunomodulator in biodegradable nanoparticles to induce antigen-specific immune tolerance to mitigate the formation of anti-drug antibodies (ADAs) in response to life-sustaining biologic drugs. The Company’s technology allows for the design of SVP therapies that can stimulate immune responses against a range of relevant antigens. Its initial immune-stimulating product candidate is a synthetic vaccine against nicotine for the market of smoking cessation and relapse prevention.
