Data from J&J's Majestic 3 trial suggests its off-the-shelf bispecific combination could rival the efficacy of its own blockbuster CAR-T, Carvykti. This sets up an internal competition where a more accessible therapy could challenge a complex, personalized one in earlier lines of treatment.

An innovative strategy for solid tumors involves using bispecific T-cell engagers to target the tumor stroma—the protective fibrotic tissue surrounding the tumor. This novel approach aims to first eliminate this physical barrier, making the cancer cells themselves more vulnerable to subsequent immune attack.

An expert argues the path to curing metastatic cancer may mirror pediatric ALL's history: combining all highly active drugs upfront. Instead of sequencing treatments after failure, the focus should be on powerful initial regimens that eradicate cancer, even if it means higher initial toxicity.

The panel reviews advanced, second-line ADC trials in China using novel targets and payloads. An expert remarks that these are the drugs and questions the US and Europe may only begin to study in two to three years, signaling a significant shift in the global oncology R&D landscape.

With highly active agents yielding 30% complete response rates, the immediate goal should be to cure more patients by exploring potent combinations upfront. While sequencing minimizes toxicity, an ambitious combination strategy, such as ADC doublets, offers the best chance to eradicate disease and should be prioritized in clinical trials.

Despite exciting early efficacy data for in vivo CAR-T therapies, the modality's future hinges on the critical unanswered question of durability. How long the therapeutic effects last, for which there is little data, will ultimately determine its clinical viability and applications in cancer versus autoimmune diseases.

While complex gene editing may be challenging in vivo, Colonia's platform presents a novel opportunity: targeting different immune cell types (e.g., T-cells and NK cells) with distinct payloads in a single treatment. This could create synergistic, multi-pronged attacks on tumors, a paradigm distinct from current ex vivo methods which focus on engineering a single cell type.

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.

Create Medicines chose LNP-delivered RNA for its in vivo platform to give physicians control. Unlike permanent lentiviral approaches, repeatable dosing allows for adapting to tumor antigen escape and managing durability and safety over time. This flexibility is a core strategic advantage for complex diseases like solid tumors.
