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

• 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.

• 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.

We are seeking a hands‑on, detail‑oriented Scientist with a strong background in Protein Science and Antibody Engineering to join the Department of Protein Engineering at Summit Therapeutics. The successful candidate will drive our antibody discovery campaigns by conducting the end‑to‑end process of engineering, generating, purifying, and characterizing high‑quality therapeutic candidates. You will work at the intersection of engineering and biology to help build our next‑generation pipeline.

• Carry out end‑to‑end antibody engineering campaigns by leveraging extensive hands‑on expertise in protein expression, purification, engineering, characterization, and a deep foundational understanding of biochemistry and molecular biology.
• Execute complex experiments with a high degree of precision; be detail‑oriented, responsible for rigorous data analysis, proactive troubleshooting, and communicating key findings during lab meetings to drive project milestones.
• Generate high quality antigens and antibodies for protein engineering campaigns in various host cells, with focus on the HEK and CHO cell systems.
• Assist in designing antibody expression constructs and generating antibody libraries using molecular biology techniques such as RT‑PCR, gene cloning, transformation, etc.
• Utilize FACS sorting and NGS to analyze libraries and screen for top‑tier lead candidates for binder affinity maturation and develop ability optimization.
• Perform the purification of antibodies and recombinant proteins using AKTA FPLC and manual methods, ensuring quality through mass spectrometry and HPLC, etc.
• Work with CRO or execute rigorous testing in house of purified proteins using SEC, SDS‑PAGE, Western blot, SPR, BLI, antibody epitope binning, etc.
• Work closely with other scientists and cross‑functional teams for project development.
• All other duties as assigned.

• Master’s in Biochemistry or related with 6+ years’ relevant experience is required. A Ph.D’s degree within 3+ years’ subject matter expertise are preferred.
• Recombinant protein and antibody production in mammalian or insect cells, experience on protein purification system…
