    Brian Cheng's questions to Allogene Therapeutics Inc (ALLO) leadership • Q2 2025

    Question

    Brian Cheng followed up on the 30% MRD conversion delta success bar, questioning if it was a fair benchmark to translate from later-line trials to the earlier first-line consolidation setting and whether a higher bar should be expected.

    Answer

    David Chang, CEO, defended the reference point, stating that the second-line randomized studies for Yescarta and Briansi are a good benchmark, provided one accepts the premise that MRD conversion is analogous to a complete remission (CR). He believes this comparison provides a solid basis for what could yield a clinically meaningful EFS benefit, though the ALPHA-three study will be the ultimate test.

    Brian Cheng's questions to Allogene Therapeutics Inc (ALLO) leadership • Q4 2024

    Question

    Brian Cheng asked for the company's latest thinking on potentially using milder lymphodepleting agents or removing them entirely for ALLO-329, and the timeline to determine the best approach.

    Answer

    President and CEO Dr. David Chang clarified that the Phase I RESOLUTION trial is designed to answer this directly. The study will include parallel cohorts: one using a milder lymphodepletion regimen of cyclophosphamide alone (without fludarabine), and another testing ALLO-329 with no lymphodepletion, relying on the Dagger technology.

    Brian Cheng's questions to Roivant Sciences Ltd (ROIV) leadership

    Brian Cheng's questions to Roivant Sciences Ltd (ROIV) leadership • Q1 2026

    Question

    Brian Cheng inquired about the upcoming top-line data release for brepocitinib in dermatomyositis (DM), the expected timeline for an FDA filing, and the rationale for testing a lower 300mg dose of IMVT-1402 in the second Graves' disease trial.

    Brian Cheng's questions to Roivant Sciences Ltd (ROIV) leadership • Q4 2025

    Question

    Brian Cheng of J.P. Morgan inquired about the definition of a successful outcome for the upcoming dermatomyositis (DM) trial and the focus of the June investor event. He also asked for clarification on the recent docket update regarding the narrowing of claims in the LNP litigation against Moderna.

    Answer

    CEO & Director Matt Gline explained that a "win" in the DM trial simply means a statistically significant separation from placebo, given the high unmet need. He stated the June event aims to educate investors on DM, trial endpoints, and the commercial opportunity. Regarding the litigation, Gline described the claim narrowing as a normal, procedural step to simplify the case for a jury trial and not indicative of any significant development.

    Brian Cheng's questions to Roivant Sciences Ltd (ROIV) leadership • Q3 2025

    Question

    Brian Cheng asked about Roivant's commitment to advancing IMVT-1402 into MG and CIDP irrespective of upcoming data, and sought details on the brepocitinib sarcoidosis trial's design and rationale.

    Answer

    CEO Matthew Gline responded that while they will use the data to inform development, MG and CIDP are large markets where IMVT-1402 has unique advantages in form factor and dosing, so the data isn't the sole determinant for proceeding. For the sarcoidosis trial, he reiterated it's a small, signal-finding study not powered for a specific statistical endpoint, noting the large effect size in a prior IIT study and a low expected placebo response.

    Brian Cheng's questions to Zymeworks Inc (ZYME) leadership • Q1 2025

    Question

    Brian Cheng of JPMorgan asked about the potential impact of the ex-U.S. patient population on the zanidatamab Phase III HERIZON-GA trial outcome, referencing subset analysis from KEYNOTE-811. He also requested an update on the J&J KLK2 bispecific program and the financial terms of the partnership.

    Answer

    CEO Kenneth Galbraith addressed the trial question, stating that while a KEYNOTE-811 sub-analysis showed some variance, KOLs generally don't see significant efficacy differences across ethnicities, and the HERIZON-GA01 trial is globally diverse. Regarding the J&J partnership, he noted Zymeworks is entitled to future development milestones and a mid-single-digit royalty on sales of the KLK2 product, expressing optimism based on J&J's public comments.

    Brian Cheng's questions to Immunovant Inc (IMVT) leadership

    Brian Cheng's questions to Immunovant Inc (IMVT) leadership • Q3 2024

    Question

    Speaking on behalf of Brian Cheng, an analyst asked how the extrathyroidal benefits from the Graves' trial read through to the ongoing Thyroid Eye Disease (TED) trial and about the updated timeline. A follow-up question for Dr. Taylor concerned the future sequencing of FcRn inhibitors in RA treatment.

    Answer

    Executive Peter Salzmann explained that while the TED trial population is more severe, seeing benefits in the milder Graves' population is encouraging for an early-treatment strategy. The TED timeline was updated due to high competition for a narrow patient group. Dr. Peter Taylor opined that due to the availability of cheaper biosimilars, FcRn inhibitors in RA would likely remain a therapy for the difficult-to-treat population, which represents the highest unmet need.

    Question

    Miriam, on behalf of Brian Cheng from JPMorgan Chase & Co., asked how the extrathyroidal benefits in Graves' disease read through to the TED trial and about the updated timeline. She also inquired about the potential real-world sequencing of FcRn inhibitors in RA.

    Answer

    Executive Peter Salzmann stated that seeing proptosis changes in the Graves' trial (which had milder TED) is encouraging for the goal of treating TED earlier. He attributed the updated TED trial timeline to increased competition for eligible patients. Dr. Peter Taylor opined that for RA, FcRn inhibitors would likely be used in the difficult-to-treat population due to the prevalence of less expensive biosimilars and generics in earlier lines of therapy.
