Kalaris Therapeutics, Inc., a clinical-stage biotech focused on retinal diseases, reported continued losses as it advances lead anti-VEGF candidate TH103. For the quarter ended June 30, 2026, net loss was $11.5 million, and for the first half of 2026, net loss was $22.4 million, with no product revenue.

Material weaknesses in internal control over financial reporting are disclosed among key risks.

Kalaris Therapeutics reported positive additional data from its expanded Phase 1a single ascending dose trial of TH103 in treatment-naïve neovascular age-related macular degeneration. The dataset now covers 17 treatment-naïve and 3 treatment-experienced patients, all followed for six months, and continues to show robust structural and functional vision improvements.
TH103 demonstrated pharmacokinetics suggesting extended intraocular retention, with 27- to 53-fold lower plasma Cmax than leading anti-VEGF agents on a molar basis. After a single injection, 41% of treatment-naïve patients were retreated at four months or later and 29% needed no additional anti-VEGF therapy over six months; treatment-experienced patients saw an average two‑month extension in retreatment intervals. No intraocular inflammation occurred in six patients at the 2.5 mg dose produced with an improved process, while one prior 5 mg patient had transient inflammation that resolved. Kalaris is enrolling a Phase 1b/2 multiple-ascending dose study using a four-dose loading regimen in treatment-naïve patients and remains on track to share initial data in the first half of 2027; investor materials also indicate cash runway into Q4 2027.
