Topline data from two ongoing COVID-19 studies with KB109 expected in Q1 2021

KB295 study in patients with ulcerative colitis remains on track with topline data anticipated mid-year 2021

LEXINGTON, Mass., March 03, 2021 (GLOBE NEWSWIRE) -- Kaleido Biosciences, Inc. (Nasdaq: KLDO), a clinical-stage healthcare company with a differentiated, chemistry-driven approach to targeting the microbiome to treat disease and improve human health, today reported financial results for the fourth quarter and full year ended December 31, 2020.

“In 2020, our Company achieved several important financial and clinical milestones that have positioned us for a productive and busy year ahead. Supported by our recently completed financing, we are beginning the year with a strong cash position, enabling continued growth and expansion of our broad, Microbiome Metabolic Therapies (MMT^TM)-based pipeline,” said Dan Menichella, President and Chief Executive Officer of Kaleido. “Recently we reported positive interim results from K031, one of two ongoing non-IND controlled clinical studies of KB109 evaluating outpatients with mild-to-moderate COVID-19 disease. Results demonstrated favorable safety and tolerability as well as evidence of clinical benefit for subjects reporting one or more comorbidities. We look forward to reporting data from both of our KB109 studies in the first quarter of 2021, including the full study population in the K031 study as well as topline results from the K032 study.”

Continued Mr. Menichella: “While our immediate priority remains advancing KB109 in COVID-19, we continue to make strong progress across our entire pipeline of novel, targeted, MMT therapies. We are currently enrolling patients in our recently initiated study of KB295 for the treatment of mild-to-moderate ulcerative colitis with topline data targeted for mid-year and continue to advance our Phase 2 clinical trial with KB195 in patients with urea cycle disorder. We are also looking forward to advancing our preclinical programs, particularly in immuno-oncology, cardiometabolic and liver diseases, and around an existing partnership with Janssen to deepen our understanding of how MMTs could potentially play a role in the prevention of childhood-onset atopic and immune conditions.”

Recent Program and Corporate Highlights

• Interim analysis (n=176) from a controlled non-IND clinical study of KB109 in patients with mild-to-moderate COVID-19 demonstrates favorable safety and tolerability, and provides strong signal of clinical benefit for subjects reporting one or more comorbidities
  

• In February, Kaleido closed a public offering with gross proceeds of approximately $69.4 million, before deducting underwriting discounts and commissions and other offering expenses

Anticipated Near-Term Milestones

• Topline data from full study population (n=350) from a non-IND clinical study of KB109 in patients with mild-to-moderate COVID-19 as well as results from a second similar study expected in Q1 2021
  

• Topline data from a non-IND clinical study of KB295 in patients with mild-to-moderate ulcerative colitis (UC) expected in mid-2021

Fourth Quarter and Full Year 2020 Financial Results

Kaleido reported a net loss of $20.0 million, or $0.56 per common share, for the fourth quarter of 2020 compared to $19.5 million, or $0.65 per common share, for the same period in 2019. For the full year 2020, Kaleido reported a net loss of $81.6 million, or $2.44 per common share, compared to $86.3 million, or $3.36 per common share, for the prior year. The 2020 fourth quarter net loss includes non-cash stock-based compensation expenses of $2.8 million, as compared to $2.2 million in the fourth quarter of 2019. The full year 2020 net loss included non-cash stock-based compensation expenses of $12.7 million, as compared to $10.1 million in 2019.

Research and development (R&D) expenses were $14.3 million and $14.1 million for the three months ended December 31, 2020 and 2019, respectively. R&D expenses were $56.0 million and $64.2 million for the year ended December 31, 2020 and 2019, respectively. The full year decrease was primarily due to reduced headcount in our R&D function and less spend with external support for our clinical studies with external CROs and external CMOs and preclinical and clinical development activities. These decreases were partially offset by increased professional and consulting spend related to our studies and increased operating costs related to our facility expansion.

General and administrative (G&A) expenses were $5.2 million and $4.9 million for the three months ended December 31, 2020 and 2019, respectively. G&A expenses were $23.9 million and $22.4 million for the year ended December 31, 2020 and 2019, respectively. The full year increase was primarily due to the modification of the vesting provision of stock options and restricted stock units related to the resignation of our former CEO and increased operating costs related to our facility expansion. These increases were partially offset by reduced headcount in our G&A functions.

As of December 31, 2020, the Company reported cash and cash equivalents of $46.2 million. Following the close of the February 2021 public offering, the Company has cash runway into the first quarter of 2022.

About Microbiome Metabolic Therapies (MMT™)
Kaleido’s Microbiome Metabolic Therapies, or MMTs, are designed to drive the function and distribution of the microbiome’s existing microbes in order to decrease or increase the production of metabolites, or to advantage or disadvantage certain bacteria in the microbiome community. The Company’s initial MMT candidates are targeted, synthetic glycans that are orally administered, have limited systemic exposure, and are selectively metabolized by enzymes in the microbiome. Kaleido utilizes its discovery and development platform to study MMTs in microbiome samples to rapidly advance MMT candidates rapidly into clinical studies in healthy subjects and patients. These human clinical studies are conducted under regulations supporting research with food, evaluating safety, tolerability and potential markers of effect. For MMT candidates that are further developed as therapeutics, the Company conducts clinical trials under an Investigational New Drug (IND) or regulatory equivalent outside the U.S., and in Phase 2 or later development.
