Radiotracers and ADC Targeting: Scientific Insights for In Vivo Validation and Clinical Transition

Biotech, Drug Discovery & Development, Life Science, Preclinical,
  • Tuesday, August 12, 2025 | 11am EDT / 8am PDT / 4pm BST / 5pm CEST
  • 60 min

Radiotracer and antibody-drug conjugate (ADC) development both demand precision. But how confident can teams be that the molecule is hitting the right target, in the right tumors, at the right time?

This webinar is designed specifically for teams developing ADCs or biologics aiming to make faster, more informed go/no-go decisions. Learn how radiolabeling provides real-time biodistribution data across clinically relevant patient-derived xenograft (PDX) models — revealing precisely where it’s going, how much it reaches the tumor and whether the targeting is genuinely effective.

 

Join the featured speakers to explore:

  • Real-world examples of how radiolabeled ADCs and biologics are being applied in preclinical research today
  • Scientific considerations for transitioning from standard ADC payloads to radiolabeled approaches
  • How imaging-based targeting validation can align R&D goals with regulatory and clinical expectations

Register for this webinar to discover how radiotracers and ADC targeting strategies can improve preclinical decision-making and enhance translational success. 

Speakers

Dr. Shankar Vallabhajosula, PhD, Professor of Radiochemistry and Radiopharmacy, Weill Cornell Medical College

Shankar Vallabhajosula received his BS and MS degrees in Pharmaceutical Sciences from Andhra University (1969 and 1971), Visakhapattanam. After working for a couple of years at Biological Evans, Hyderabad, and All-India Institute of Medical Sciences, New Delhi, he immigrated to United States in 1994.

In New York, after working for two years in Nuclear Medicine, he received his board certification as a Nuclear Medicine Technologist in 1976. Subsequently, he pursued graduate studies in Biomedicinal Chemistry/Radiopharmacy from the School of Pharmacy at the University of Southern California, Los Angeles, and received his PhD in 1980.

Dr. Vallabhajosula started his academic career in 1980, first at Mount Sinai Medical Center, and later at Weill Cornell Medicine in New York. Throughout his four-decade academic career, Dr. Vallabhajosula has been dedicated to advancing patient care through nuclear medicine. He has published more than 130 articles in major scientific journals and was responsible for obtaining more than 20 investigational new drugs (INDs) for positron emission tomography (PET) and therapeutic radiopharmaceuticals. In 2004, he received a new drug application (NDA) for the manufacture of [18F] Fludeoxyglucose (FDG) at WCM. As a research collaborator for four decades, Dr Vallabhajosula participated in the development and manufacture of more than 30 different IND radiopharmaceuticals.

Dr. Vallabhajosula is a Professor Emeritus of Radiochemistry/Radiopharmacy in Radiology at WCM of Cornell University, New York, NY. He also served as the President and Chief Scientific Officer for four years at NCM USA, a radiopharmaceutical manufacturing company for PET and targeted radionuclide therapy. Since February 2023, Dr. Vallabhajosula has served as the Vice President of Radiopharmaceutical Sciences at Convergent Therapeutics Inc., Cambridge, MA.

Dr. Vallabhajosula has been an active member of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and served as an associate editor of the Journal of Nuclear Medicine (1994-1998). For his contributions to the basic and clinical science of nuclear medicine, Dr. Shankar received the Berson and Yalow award in 2007 by the Greater New York Chapter of Nuclear Medicine, and the Lifetime Achievement Award in 2022 by the General Clinical Nuclear Medicine Council of the SNMMI. Dr. Vallabhajosula published two single-author textbooks: “Molecular Imaging: Radiopharmaceuticals for PET and SPECT” (Springer Verlag, 2009) and a second and revised edition “Molecular Imaging and Targeted Therapy: Radiopharmaceuticals and Clinical Applications” (Springer Nature 2023).

Who Should Attend?

This session is for scientific and strategic leaders at ADC-focused biotechs who need to improve targeting validation and make better decisions before clinical investment. Ideal attendees include:

  • Chief Scientific Officers (CSOs) and Heads of R&D looking to reduce late-stage attrition
  • Translational Leads and Preclinical Scientists evaluating antibody behavior in vivo
  • VPs of Oncology or Targeted Therapeutics seeking better IND-enabling data
  • Business Development or Program Strategy Directors considering modality-enhancing tools
  • Anyone advancing an ADC or biologic program into preclinical IND-enabling work
  • Program Leads managing early-stage ADC or antibody programs nearing go/no-go decision points

What You Will Learn

Attendees will gain insight into:

  • How radiotracers (radiolabeled ADCs/biologics) provide preclinical insight into antibody targeting beyond what efficacy alone can show
  • How to use biodistribution and imaging studies to select better leads, avoid off-target liabilities and improve clinical confidence
  • Why PDX models offer the best platform for translationally relevant targeting data in ADC development
  • A practical framework for integrating radiolabeling into an existing preclinical workflow, without rebuilding a program
