  • Abcuro

    Participated · Series D · Aug 2026

    Abcuro develops immunotherapies intended to benefit people with debilitating and progressive rare autoimmune diseases by selectively targeting and depleting highly cytotoxic T cells. Its lead program, ulviprubart, is a monoclonal antibody that targets killer cell lectin like receptor G1 (KLRG1) and is currently being evaluated for the treatment of Inclusion Body Myositis (IBM). The company plans to use proceeds from the Series D to support a new potentially registrational clinical study of ulviprubart in patients with less severe IBM. Abcuro is led by CEO Alex Martin and is based in Newton, MA. Financially, it has just completed a $66M Series D financing led by New Leaf Venture Partners with participation from a broad syndicate of life sciences and strategic investors.

  • Slate Medicines

    Participated · Equity · Aug 2026

    Slate Medicines is advancing a pipeline of migraine antibody therapeutics designed to go beyond existing CGRP-targeted treatments. Its lead candidate, SLTE-1009 (licensed from DartsBio Pharmaceuticals), is a monoclonal antibody that targets both PACAP and VIP, and the company’s second program, SLTE-2100, is a bispecific antibody combining CGRP and PACAP/VIP blockade. Slate plans to report Phase I safety and PK data for SLTE-1009 in mid-2027 and to start a Phase II migraine study in the second half of 2027. The company positions its dual-targeting approach as potentially offering greater efficacy versus PACAP-only therapies in a market where CGRP-targeted products generated roughly $5 billion in 2025 sales. Slate recently secured a $245 million financing via a reverse merger and private placement and had raised $130 million in a Series A earlier the same year, giving it runway into 2029.

    Khartis Therapeutics is developing a pipeline of oral small molecule medicines, with a lead program that is an oral selective IGF-1R inhibitor designed for thyroid eye disease. The company is also advancing additional oral small-molecule programs against clinically validated immunology pathways. Khartis was founded in 2024 by Robert Hoffman (CEO and Head of Drug Discovery), Craig Murphy (CSO), and Chris LeMasters (Executive Chairman), and was incubated within Foresite Labs.
