    Sean Lee's questions to Alphatec Holdings (ATEC) leadership

    Sean Lee's questions to Alphatec Holdings (ATEC) leadership • Q2 2025

    Question

    Sean Lee asked for anecdotal evidence on the rate at which new surgeons, after training, are adopting ATEC's more advanced procedures like PTP or complex deformity.

    Answer

    Chairman & CEO Pat Miles provided an anecdotal view, explaining that the PTP procedure often reinvigorates interest from surgeons who had previously dismissed lateral surgery because it solves key challenges with alignment and access. He believes that integrating navigation will further "democratize" the technique, making more surgeons comfortable and expanding the user base for these advanced procedures.

    Sean Lee's questions to PLUS THERAPEUTICS (PSTV) leadership

    Sean Lee's questions to PLUS THERAPEUTICS (PSTV) leadership • Q4 2024

    Question

    Sean Lee of H.C. Wainwright posed several questions regarding the Leptomeningeal Metastases (LM) program and the CNSide diagnostic. He asked if the 44 millicurie dose expansion is part of Phase I or a new Phase II, questioned the timing of the multi-dose study relative to a potential Phase II trial, and inquired about the market opportunity for CNSide.

    Answer

    President and CEO Marc Hedrick clarified his aspiration is for the dose expansion to be a Phase II trial focused on breast cancer patients, subject to FDA agreement, which could potentially roll directly into an approval trial. He confirmed they will proceed with a single-dose trial (Phase Ib or II) without waiting for multi-dose data, as the single-dose data is already very promising. Regarding CNSide, Hedrick estimated a U.S. market opportunity of up to 500,000 tests per year and expects the tumor cell enumeration test to be commercially rolled out geographically over the next year.
