Kala Pharmaceuticals Acquires Combangio

Kala Pharmaceuticals, Inc. a commercial-stage biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies for diseases of the eye, announced that it has acquired Combangio, Inc., a private, clinical-stage company developing regenerative biotherapies for severe ocular surface diseases. Combangio is developing CMB-012, a novel investigational secretome therapy, now known as KPI-012, to address the complex wound healing process in persistent corneal epithelial defect (PCED) and other severe ocular diseases driven by impaired corneal healing.

“Today’s acquisition marks a pivotal moment for Kala and a meaningful acceleration toward our goal of strengthening Kala’s pipeline for the treatment of front and back of the eye diseases,” said Mark Iwicki, Chief Executive Officer of Kala. “KPI-012 is a highly innovative product, which leverages a multifactorial mechanism of action to address the complex process of healing severe corneal defects. KPI-012 is currently in development for PCED, with potential application across a wide range of orphan diseases of the eye. This product candidate is a natural fit with our R&D and commercial expertise, and along with our internal pipeline provides an additional opportunity to leverage our deep ophthalmic expertise to address substantial, underserved markets. We are excited to have completed the acquisition of Combangio and look forward to working alongside their talented team to integrate KPI-012 into our portfolio and ultimately deliver this therapy to transform the treatment of rare ocular surface diseases.”

KPI-012 is a novel bone marrow-derived mesenchymal stem cell (MSC) secretome comprised of biomolecules secreted by MSCs, including protease inhibitors, growth factors and neurotrophic factors, processed into a topical ocular solution. KPI-012 is currently in clinical development for the treatment of PCED, which is defined as a persistent non-healing corneal defect or wound that is refractory to conventional treatments. It is a rare disease with an estimated incidence in the U.S. of 100,000 cases and 238,000 cases in the U.S., E.U. and Japan combined and KPI-012 has received Orphan Designation for the treatment of PCED by the U.S. Food and Drug Administration (FDA). PCED can have various etiologies including neurotrophic keratitis, epithelial debridement, microbial/viral keratitis, corneal transplant, limbal stem cell deficiency and trauma, and can lead to corneal ulceration, perforation, scarring, infection and significant vision loss.

In a Phase 1b clinical trial, seven of eight PCED patients treated with KPI-012 twice-daily showed improvement in their PCED, with six of the eight achieving complete healing during the treatment period, which ranged from one to eight weeks. Four of eight patients had complete healing within one week of treatment with the other two that achieved complete healing doing so within two to four weeks of initiation of treatment with KPI-012. All six of the healed patients remained healed through the end of follow-up, which ranged between eight and 19 weeks. There was also significant pain relief in the six patients who reported pain at baseline, with all six achieving a zero-pain score within three weeks of initiation of dosing with KPI-012.   KPI-012 was well-tolerated in the trial with no treatment-related safety issues observed.

“KPI-012 is an exciting addition to the Kala pipeline and is an important component of our strategy to develop novel therapies for significant unmet needs in ophthalmic diseases. People living with severe ocular surface diseases are in desperate need of new and better therapeutic options to not only provide symptomatic relief but to avoid the potential vision-threatening consequences of these diseases,” said Kim Brazzell, Ph.D., Chief Medical Officer of Kala. “The Phase 1b clinical data are very encouraging for PCED as well as for other rare ocular diseases that involve impaired corneal wound healing. We look forward to working together with our extensive network of corneal specialists to advance this program through clinical development and regulatory approval.”
