Radiopharmaceuticals can use the same molecular scaffold for diagnosing a tumor with one radionuclide and treating it with another. This "theranostic" strategy improves patient stratification and accelerates the transition from diagnosis to effective therapy.

A key operational challenge in radiopharmaceutical development is the need for a reliable supply of radionuclides for fresh, just-in-time labeling before dosing. This contrasts sharply with conventional drugs that can be manufactured in bulk and stored, adding significant logistical complexity.

To overcome on-target, off-tumor toxicity, LabGenius designs antibodies that act like biological computers. These molecules "sample" the density of target receptors on a cell's surface and are engineered to activate and kill only when a specific threshold is met, distinguishing high-expression cancer cells from low-expression healthy cells.

The traditional drug-centric trial model is failing. The next evolution is trials designed to validate the *decision-making process* itself, using platforms to assign the best therapy to heterogeneous patient groups, rather than testing one drug on a narrow population.

The future of medicine isn't about finding a single 'best' modality like CAR-T or gene therapy. Instead, it's about strategic convergence, choosing the right tool—be it a bispecific, ADC, or another biologic—based on the patient's specific disease stage and urgency of treatment.

With over 5,000 oncology drugs in development and a 9-out-of-10 failure rate, the current model of running large, sequential clinical trials is not viable. New diagnostic platforms are essential to select drugs and patient populations more intelligently and much earlier in the process.

In oncology R&D, a successful two-drug combination isn't the final goal but the new standard of care to build upon. Researchers immediately begin planning for "triplets"—adding a third agent to the successful doublet—demonstrating a relentless, forward-looking strategy to incrementally improve patient outcomes.

A practical method to monitor radioligand therapy is a post-treatment SPECT scan. Since the therapeutic agent is radioactive, a simple planar scan about 24 hours after injection can visually confirm where the drug was delivered. This provides real-time feedback, beyond PSA levels, to potentially adapt treatment.

Historically, intratumoral therapy was limited by the physical difficulty of reaching tumors. The rise of a new discipline, Interventional Oncology, has largely solved this access problem. The critical bottleneck is now the lack of drugs specifically designed and optimized for local delivery and sustained retention within the tumor.

Rather than moving through distinct lines of therapy, a future strategy could involve an "ADC switch." When a patient progresses on an ADC-IO combination, the IO backbone would remain while the ADC is swapped for one with a different, non-cross-resistant mechanism, adapting the treatment in real-time.

Fibrogen uses its PET imaging agent in Phase 2 not to pre-select patients, but to correlate target expression with treatment response. This data will allow them to enrich their Phase 3 trial with patients most likely to respond, significantly increasing the probability of success.
