CAMBRIDGE, Mass., Aug. 4, 2022 — Codiak BioSciences, Inc. (NASDAQ: CDAK), a clinical-stage biopharmaceutical company pioneering the development of exosome-based therapeutics as a new class of medicines, today reported second quarter 2022 financial results and recent operational progress.

“During the second quarter we made strong progress supporting our approach and making advancements across our pipeline. We reported Phase 1 data sets from both our exoSTING^™ and exoIL-12^™ programs, further validating our engEx^® platform, and demonstrating we were able to deliver repeat doses of exoSTING and exoIL-12 to the tumor with a high level of specificity. Importantly, we did so with no observed systemic exposure or associated toxicity, and an enhanced therapeutic index – while demonstrating tumor shrinkage in both injected and uninjected lesions,” said Douglas E. Williams, Ph.D., President and CEO of Codiak. “We also initiated a Phase 1 study of exoASO^™-STAT6, our third program to enter the clinic, in patients with certain liver, gastric and colorectal cancers. These updates, in combination with preclinical data showing the promise of our engEx-AAV^™ program and a partnership with CEPI to advance our pan Betacoronavirus program, show that Codiak is broadly advancing its portfolio programs in 2022, momentum we aim to carry through this year and into 2023.”

Second Quarter 2022 and Recent Highlights

• Announced platform-validating data from Phase 1 trials of exoSTING^™ and exoIL-12^™; both candidates demonstrated potential for best-in-class profile; Codiak has identified a recommended Phase 2 dose for each program and intends to finalize study plans with the FDA during the second half of this year to prepare for initiation of Phase 2 trials for both candidates early next year.

• In a Phase 1 trial, exoIL-12 demonstrated a differentiating safety and tolerability profile, with no detectable systemic exposure of IL-12 and no treatment-related adverse events, which has not previously been reported by others with recombinant IL-12. The two patients with cutaneous T cell lymphoma (CTCL) who have been treated each received multiple (>20) injections of exoIL-12 and experienced tumor regressions in both injected and non-injected lesions, including a partial response in one patient.

• In the Phase 1/2 clinical trial evaluating exoSTING as a single agent in patients with late-stage refractory solid tumors, data across all five dose cohorts showed repeat doses of exoSTING were well-tolerated, demonstrated tumor retention with no systemic exposure of the STING agonist, and in a subset of patients, tumor shrinkage was observed in injected and uninjected lesions.

• Initiated patient dosing in the Phase 1 clinical trial of exoASO^™-STAT6 in patients with advanced hepatocellular carcinoma, liver metastases from primary gastric cancer and colorectal cancer; exoASO-STAT6 is Codiak’s third clinical program and the first to evaluate a systemically administered exosome-based drug candidate.

• Partnered with CEPI to continue the advancement of vaccine candidates from the Company’s pan Betacoronavirus program; as part of the partnership, CEPI will provide seed funding of up to $2.5 million, which Codiak anticipates will fund the completion of preclinical development and identification of a clinical candidate.

• Presented preclinical data on the Company’s engEx-AAV^™ discovery program, a novel strategy that aims to leverage exosomes to improve adeno-associated virus (AAV) vector gene therapy, at the 25th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT); data demonstrated that exosome engineering generates significant increases in AAV yield compared to unmodified exosomes, while retaining the functionality to transduce cells with AAV and resist neutralizing antibodies that impair gene therapy efficacy.

Anticipated Milestones and Events

• Initiate Phase 2 study of exoIL-12 in an expanded group of tumor types in 1H 2023; continue to monitor patients enrolled in Phase 1 study

• Initiate Phase 2 study of exoSTING^™ in bladder cancer in 1H 2023; continue to monitor patients enrolled in ongoing Phase 1/2 study, reporting additional data at an upcoming scientific conference

• Continue enrollment for ongoing Phase 1 trial for exoASO-STAT6, with initial data expected in 1H 2023

• Advance exoVACC^™ pan Betacoronavirus program toward identification of a clinical candidate through new partnership with CEPI

Second Quarter 2022 Financial Results

Total revenues for the quarter ended June 30, 2022, were $13.1 million, compared to $0.9 million for the same period in 2021. These results reflect deferred revenue recognized under the Company’s collaboration with Jazz Pharmaceuticals.

Net loss for the quarter ended June 30, 2022, was $6.8 million, compared to a net loss of $21.8 million for the same period in 2021. The decrease in net loss for the quarter was driven primarily by an increase in revenues in connection with the Company’s agreement with Jazz Pharmaceuticals.

Research and development expenses were $12.8 million for the quarter ended June 30, 2022, compared to $15.4 million for the same period in 2021. The decrease in research and development expenses was driven primarily by decreases in lab expenses and personnel-related costs in connection with the Company’s agreement with Lonza.

General and administrative expenses were $7.4 million for the quarter ended June 30, 2022, compared to $6.9 million for the same period in 2021. The increase was due primarily to professional services driven by legal fees for intellectual property rights.

As of June 30, 2022, Codiak had cash, cash equivalents, and marketable securities of approximately $41.8 million.
