Summit’s team is inspired to touch and help change lives through Summit’s clinical studies in the field of oncology. Summit has multiple global Phase 3 clinical studies, including: Non-small Cell Lung Cancer (NSCLC) HARMONi: Phase 3 clinical study which was intended to evaluate ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who were previously treated with a 3rd generation EGFR TKI. HARMONi-3: Phase 3 clinical study which is intended to evaluate ivonescimab combined with chemotherapy compared to pembrolizumab combined with chemotherapy in patients with first-line metastatic NSCLC. HARMONi-7: Phase 3 clinical study which is intended to evaluate ivonescimab monotherapy compared to pembrolizumab monotherapy in patients with first-line metastatic NSCLC. Colorectal Cancer (CRC) HARMONi-GI3: Phase 3 clinical study intended to evaluate ivonescimab in combination with chemotherapy compared with bevacizumab plus chemotherapy. Ivonescimab is an investigational therapy not presently approved by any regulatory authority other than China’s National Medical Products Administration (NMPA). Summit is headquartered in Miami, Florida, and has additional offices in California, New Jersey, the UK, and Ireland. Overview of Role:   The Associate Director of Analytical Development and CMC Statistics will provide technical and statistical leadership for analytical development, method validation, method transfer, comparability, stability, specifications, and lifecycle management activities supporting biologic drug substance and drug product programs. This role will sit within the CMC Analytical Sciences organization and will partner closely with Analytical, MSAT, Quality, Regulatory Affairs, Supply Chain, and external CDMOs/CROs to ensure that analytical strategies, statistical approaches, and data packages are scientifically robust, phase-appropriate, compliant, and suitable for global regulatory submissions and commercial readiness.   The successful candidate will combine hands-on experience in biologics analytical development with strong statistical expertise, including method validation statistics, stability and shelf-life modeling, specification setting, comparability assessments, assay lifecycle monitoring, and statistical support for CMC investigations. This individual will be expected to translate complex analytical datasets into clear conclusions, support risk-based decision-making, and contribute directly to IND/IMPD, BLA/MAA, post-approval, and health authority response activities.   Role and Responsibilities:   Provide scientific and technical leadership for analytical method development, qualification, validation, transfer, troubleshooting, and lifecycle management for biologic drug substance and drug product programs.   Support phase-appropriate analytical strategies for release, stability, characterization, comparability, potency, binding, impurity, and residual testing.   Review and interpret analytical data from CDMOs, CROs, and partner laboratories to ensure methods are robust, fit for purpose, and aligned with regulatory expectations.   Contribute to analytical control strategy development, including critical quality attribute assessment, method performance monitoring, and product quality trend evaluation.   Lead statistical planning, analysis, and interpretation for analytical method validation, method transfer, comparability, stability, specification setting, assay qualification, and investigation support.   Apply appropriate statistical tools to evaluate accuracy, precision, linearity, range, robustness, intermediate precision, equivalence, trending, outliers, assay variability, and method capability.   Develop and justify statistically sound acceptance criteria, comparability criteria, stability models, DS and DP shelf-life determinations, stability trending approaches, and analytical control limits.   Partner with CMC, Quality, Regulatory Affairs, and external partners to ensure statistical approaches are scientifically defensible and clearly documented in protocols, reports, and regulatory submissions.   Support data visualization, multivariate analysis, and trend monitoring to enable early identification of analytical or manufacturing risks.   Support inspection readiness, audit responses, regulatory commitments, and post-approval lifecycle management activities related to analytical methods, stability, specifications, and comparability.   Provide statistical input into deviations, OOS/OOT investigations, CAPAs, change controls, and risk assessments.   Provide analytical and statistical oversight for external CDMOs, CROs, and partner laboratories performing release, stability, characterization, method transfer, method validation, and comparability studies.   Review external protocols, reports, data packages, deviations, and investigations to ensure technical quality, compliance, and alignment with program objectives.   Communicate complex analytical and statistical findings clearly to technical and non-technical stakeholders, including senior leadership.   Contribute to internal SOPs, templates, best practices, and governance processes for analytical development, CMC statistics, a
