Brief Summary

Microlyvaq™ is a first-line, non-randomized, two-arm clinical trial in advanced non-small cell lung cancer (NSCLC). In both arms, patients receive a personalized multi-epitope vaccine (Microlyvaq™) on top of standard-of-care chemo-immunotherapy, with treatment tailored by histology: Arm 1 - Squamous NSCLC: Microlyvaq™ + carboplatin AUC 5 + paclitaxel 175 mg/m² + pembrolizumab Arm 2 - Non-squamous NSCLC: Microlyvaq™ + carboplatin AUC 5 + pemetrexed 500 mg/m² + pembrolizumab Because this is a non-randomized study, patients are assigned to arms based on tumor histology (squamous vs non-squamous), not by random allocation. The core problem it addresses is that even with pembrolizumab plus histology-appropriate chemotherapy, many patients either never respond or respond briefly and then progress. Tumors evade by exhausting T cells, excluding them from the tumor bed, evolving antigen loss, and maintaining suppressive myeloid and stromal niches. Microlyvaq™ is designed to overcome these resistance modes by actively installing new, durable, polyfunctional anti-tumor immunity rather than relying only on pre-existing T cells. Here's how it works. Each patient's tumor is sequenced (whole exome and RNA-seq) to identify both well-known lung cancer-associated antigens (e.g. NY-ESO-1, SOX2, p53, MAGE-A4, BRAF, BMI1, FXR1, HuD, HuC, CAGE) and private neoantigens created by that tumor's specific mutations, fusions, and splice variants. From this large antigen pool, machine learning models score each candidate epitope for that specific patient. The models consider predicted HLA class I and II presentation, how efficiently the antigen will actually be processed and displayed, whether it's expressed in tumor but not healthy tissue, how essential it is to most malignant cells (to avoid easy escape), and whether it is likely to drive functional, non-exhausted T-cell responses. This is not a generic ranking; it is individualized per patient. The most promising epitopes then undergo a quantum molecular coupling evaluation. Instead of simply asking whether a peptide binds a given HLA, Microlyvaq™ modeling simulates the peptide-MHC complex as a physical system and approximates solutions to Ĥψ = Eψ to estimate whether the peptide will form a stable, low-energy, presentation-competent conformation that a realistic T-cell receptor can dock to without high energetic penalty. Epitopes that look good in simple binding screens but are predicted to be unstable, transient, or geometrically inaccessible to TCRs are excluded. The remaining epitope set is engineered to: (1) recruit potent CD8⁺ cytotoxic T cells that can kill tumor cells, and (2) recruit CD4⁺ Th1 helper T cells that produce IFN-γ, TNF-α, and IL-2 to sustain and support those killers. The vaccine is therefore intentionally multi-epitope, Th1-biased, and patient-specific. Each personalized Microlyvaq™ lot is manufactured under GMP and given as a prime-boost series in sync with pembrolizumab and the appropriate chemotherapy backbone for the patient's histologic arm (carboplatin/paclitaxel for squamous; carboplatin/pemetrexed for non-squamous). Timing is deliberate: chemotherapy induces immunogenic tumor cell death and antigen release and transiently "opens up" the tumor microenvironment, while pembrolizumab lifts PD-1-mediated brakes on emerging T cells. Microlyvaq™ is dosed into that vulnerable window to expand vaccine-encoded clones just as new antigen is exposed and suppression is partially relieved. The goal is to generate rapid tumor shrinkage, then sustained immune pressure on residual disease, plus epitope spreading - where the immune system begins to recognize additional tumor targets beyond those in the vaccine, making escape more difficult. The trial itself is structured as a seamless, adaptive, non-randomized Phase I/IIa study, with two predefined histology-based arms (squamous vs non-squamous) rather than randomized treatment allocations. The primary early endpoint is objective response rate (RECIST v1.1). Key secondary endpoints include progression-free survival, duration of response, and overall survival. In addition, the study incorporates real-time translational signals as decision points, including:

  1. 1.polyfunctional Th1 and CD8⁺ responses to vaccine epitopes by ELISpot/ICS,
  2. 2.durable expansion and persistence of vaccine-linked TCR clonotypes in blood and, when feasible, in tumor,
  3. 3.rapid decline in circulating tumor DNA as an early molecular marker of tumor clearance,
  4. 4.improved tumor infiltration by CD8⁺ and Th1 cells, and
  5. 5.remodeling of the tumor microenvironment away from suppressive myeloid states. If a given histology arm shows strong clinical responses plus these immune/molecular signals, that arm can seamlessly expand into survival-powered confirmation. If it does not, predefined futility rules allow that arm to stop, all within this non-randomized, adaptive framework.

Outcome Measures

Primary Outcomes (2)

  • Overall Survival (OS): AI epitope ranking, quantum energetics, TCR repertoire engineering, ctDNA collapse, spatial immune remodeling - is in service of extending OS safely. Subjects alive at cut-off are censored at last known alive.

    Overall survival is the time from first dose of study treatment to death from any cause. Survival will be summarized with Kaplan-Meier curves; between-arm comparisons will use a stratified Cox model to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). If non-proportional hazards are detected, restricted mean survival time (RMST) will be used. Stratification factors may include PD-L1 proportion score (TPS), smoking status, actionable driver status (EGFR/ALK/ROS1/ERBB2/KRAS-G12C), and geographic region. Subsequent anti-cancer therapy after progression will not reset survival time (treatment-policy strategy). Patients lost to follow-up will be censored at the last date known alive. Overall survival will be evaluated in two non-randomized histology cohorts: Arm 1 (squamous NSCLC): Microlyvaq™ + carboplatin + paclitaxel + pembrolizumab; Arm 2 (non-squamous NSCLC): Microlyvaq™ + carboplatin + pemetrexed + pembrolizumab (with folate/B12 and steroid support).

    Survival status assessed approximately every 12 weeks during long-term follow-up, through study completion, up to approximately 36 months.

  • Objective Response Rate (ORR; Confirmed CR+PR): The Microlyvaq™ vaccine is delivered into a "window of susceptibility": right when chemotherapy has induced immunogenic cell death and pembrolizumab has lifted PD-1 brakes on on exhausted T cells.

    * ORR (%) with 95% CI in the Full Analysis Set (all randomized with measurable disease at baseline). * Between-arm comparison via stratified CMH or logistic regression adjusting for prespecified strata. * Missing confirmatory scan defaults to "non-responder" in the primary analysis to avoid false inflation. In Microlyvaq™, ORR is not just "does tumor shrink." It's "does our AI / ML / quantum-informed control signal actually force the tumor-immune system into the kill state we predicted, on schedule."• Each Microlyvaq™ lot is not a fixed commercial SKU. It's a computationally composed payload of \~17-25 epitopes, each picked for that exact patient by AI/ML plus quantum energy modeling to maximize productive peptide-HLA display, stable TCR engagement geometry, and resistance to tumor immune escape. In Microlyvaq™, ORR is not just "does tumor shrink." It's "does our AI / ML / quantum-informed signal actually force the tumor-immune system into the kill state we predicted, on schedule"

    Confirmation window: Response must be confirmed 8 weeks after first CR/PR call, so typically ~Week 14 for first responders.Update cadence: Every imaging timepoint: 6 weeks through Week 24, then 12 weeks thereafter.

Secondary Outcomes (6)

  • Progression-Free Survival (PFS): Time from randomization to first of either: 1. RECIST v1.1 progression (investigator), or 2. Death from any cause. Sensitivity analysis uses blinded ERC progression calls.

    Time Frame: From baseline (scan within 28 days before Day 1) through study completion, with tumor assessments every 6 weeks through Week 24, then every 12 weeks thereafter (up to approximately 24 months).

  • Duration of Response (DoR) for confirmed responders (CR/PR)

    From end of on-treatment follow-up, survival status assessed approximately every 12 weeks through study completion, up to approximately 36 months.

  • Disease Control Rate (DCR): CR + PR + durable stable disease (SD ≥6 weeks at the first scheduled post-baseline scan).

    From the first post-baseline tumor assessment (approximately Week 6) through confirmation of disease control, with tumor assessments every 6 weeks through Week 24, then every 12 weeks thereafter through study completion (up to approximately 24

  • Time to Response (TTR):Among responders, time from randomization to first confirmed CR/PR.

    First evaluable: First scan with CR/PR (~Week 6).Confirmation anchor: Responses are only counted once confirmed 4-8 weeks later (so confirmed TTR for early responders ~Week 10-14).

  • Incidence of Treatment-Emergent Adverse Events (TEAEs)

    From first dose of any study drug through 30 days after the last dose of any study drug (up to approximately 12 months, depending on treatment duration).

  • +1 more secondary outcomes

Other Outcomes (6)

  • Incidence of Procedure-Related Serious Adverse Events (SAEs)

    From baseline (Day 1) through study completion, up to approximately 36 months.

  • Change From Baseline in EORTC QLQ-C30 Global Health Status/Quality of Life (QoL) Score

    From baseline (Day 1) through end of study or up to approximately 36 months, with EORTC QLQ-C30 assessments collected at scheduled study visits (approximately every 3 weeks through Week 24, then every 9-12 weeks thereafter).

  • Proportion of Patients Achieving ctDNA Major Molecular Response (MMR)

    From baseline (pre-treatment sample) to the first on-treatment ctDNA assessment at approximately Week 6 (with an assessment window extending up to Week 9).

  • +3 more other outcomes

Model Details: The Microlyvaq™ interventional study model is a non-randomized, seamless adaptive Phase II/III, histology-stratified trial in first-line advanced NSCLC. Patients are not randomized between regimens; instead, they are assigned to one of two predefined treatment arms solely on the basis of tumor histology: Arm 1 - Squamous NSCLC: Microlyvaq™ personalized multi-epitope vaccine administered in combination with carboplatin AUC 5, paclitaxel 175 mg/m², and pembrolizumab. Arm 2 - Non-squamous NSCLC: Microlyvaq™ personalized multi-epitope vaccine administered in combination with carboplatin AUC 5, pemetrexed 500 mg/m², and pembrolizumab. The intervention is not one-size-fits-all: within each non-randomized arm, each patient's Microlyvaq™ lot is uniquely generated using AI/ML-guided selection of neoantigens, followed by quantum molecular stability ("quantum immunogenetics") to prioritize epitopes predicted to be stably presented and highly immunogenic.
