Summary

Iovance updated its investor presentation with 2026 financial guidance and commercial progress metrics. The company expects full-year revenue of $350M–$370M, with second-quarter revenue of $86M–$88M, representing approximately 45% year-over-year growth driven by Amtagvi (its approved TIL therapy for advanced melanoma) and Proleukin sales. The $319M cash position as of March 31, 2026, provides runway into 2028.

The most significant disclosure is real-world Amtagvi response data showing a 44% overall objective response rate across 41 patients, materially higher than the 31.4% rate in pivotal trials. Patients with two or fewer prior therapies achieved a 52% response rate, suggesting the therapy may perform better when used earlier in the treatment sequence.

This real-world evidence could accelerate adoption and support label expansion efforts. The company has expanded its authorized treatment center network to over 90 sites, including its first Canadian location, broadening the infrastructure needed to deliver the complex cell therapy. Retail holders should watch $86M for Q2 earnings to confirm the guidance range and $88M for updates on treatment center activation rates, which directly impact revenue potential.

>90 Treatment Centers as of 05 /07/26* ... *Includes center s in final stages of readiness or soon to be authorized.

The company reported having over 90 authorized treatment centers (ATCs) as of May 7, 2026, including centers in final stages of readiness or soon to be authorized. This includes the first Canada ATC in Toronto. The expansion of the ATC network is critical to commercial uptake, as Amtagvi requires specialized facilities for administration and patient monitoring during the treatment regimen.

Added Real-world Amtagvi response rates high

Added in current filing · view on EDGAR → · paraphrased

44 % ORR (18/41) ... 52 % ORR (12/23) ... 33% ORR (6/18)

The company disclosed real-world objective response rates (ORR) for Amtagvi in previously treated advanced melanoma: 44% overall (18 of 41 patients), 52% in patients with two or fewer prior lines of therapy (12 of 23 patients), and 33% in patients with three or more prior lines (6 of 18 patients). These real-world data, sourced from a transplantation and cell therapy conference presentation, show higher response rates than the 31.4% ORR observed in the pivotal clinical trials, particularly in earlier treatment lines, which may support broader adoption and earlier use in the treatment paradigm.
