KEI Questions to the NIH Regarding Prospective License of T-cell Cancer Therapy to EnZeta Immunotherapies

(Update: The NIH provided a response to our questions on August 17, 2023.)

On August 11, 2023, Knowledge Ecology International (KEI) submitted questions to the National Institutes of Health regarding the “Prospective Grant of an Exclusive Patent License: Manufacture, Distribution, Sale and Use of T-Cell-Based Immunotherapies for Solid Tumors” (88 FR 54629). The technology is to be licensed to EnZeta Immunotherapies, Inc., “of the State of Delaware”.

In April 2023, a Federal Register notice was posted for a similar package of patents titled, “Prospective Grant of an Exclusive Patent License: Manufacture, Distribution, Sale and Use of T-Cell-Based Immunotherapies for Solid Tumors” (88 FR 20544). That notice was to be licensed to EnZeta, Inc., also “of the State of Delaware”.

KEI submitted the following questions regarding the recently posted license (available in PDF here).

Dear Richard Girards,

These questions are in regard to the prospective license to EnZeta Immunotherapies, published August 11, 2023, 88 FR 54629.

1. Can you tell us how this relates to a similar Federal Register Notice published April 6, 2023, 88 FR 20544, regarding a company also named EnZeta, also for T-cell-based immunotherapies for solid tumors. We notice there is some overlap in the description of the intellectual property (see below). Is it the case that the NIH is no longer negotiating the earlier prospective license, or is expanding that license? In any case, why is the NIH now offering to what we assume is essentially the same company a different bundle of patent rights in an exclusive license? Was it really necessary to include more patents in the exclusive license than were proposed in April?

2. We cannot locate a web page for EnZeta and the company does not appear to have any SEC filings and a Google search of the term “EnZeta” turns up nothing connected to the company but the two Federal Register notices. A search of the Delaware Division of Corporations records notes that EnZeta, Inc. was incorporated May 13, 2022, having the registered agent “Business Filings Incorporated,” and EnZeta Immunotherapies, Inc. was incorporated July 31, 2023, having the registered agent “Resident Agent.” Has there been a change in ownership for the new entity?

3. What are you willing to tell us about the company, regarding its ownership or management or operations? For example:

a. Who is on the Board of Directors?
b. Who are the CEO or CFO or chief medical officers?
c. Does the company have a US address other than the registered agent in Delaware?
d. Are any of the owners, board members, or key employees former employees of the NIH?
e. Who are persons or entities that own more than 5 percent of the company?
f. Is there significant foreign ownership in EnZeta?

4. Will this company be treated as a start-up company by the NIH, eligible for a 1.5 percent royalty on the license?

5. The geographic scope of the proposed license is worldwide. What evidence do you have that EnZeta will be inclined or have the capacity to make the inventions available worldwide, including in developing countries? In particular, will the NIH include working and affordability conditions to give effect to the objective of “broad accessibility for developing countries,” a goal expressed in the United States Public Health Service Technology Transfer Policy Manual, Chapter No. 300, PHS Licensing Policy?

6. Has EnZeta had discussions with the NIH regarding a waiver of US manufacturing requirements in 35 USC § 204?

7. What is the stage of development of the technology?

8. Has any US government agency funded or offered to fund any clinical trials related to this license?

9. Will the US government require that the prices for products using the licensed patents be available to the US public at prices no higher than a reference price for a set of other high-income countries with large economies? If not, why not?

10. Is the license term the same or shorter than the life of the patents, and if the same as the life of the patents, how has the NIH determined that a life of patent license term is “necessary reasonably necessary to provide the incentive for bringing the invention to practical application,” a restriction in 35 USC § 209(a)(2), as compared to an exclusivity term-limited in time, such has been used in for past for licenses on NIH-owned patents, such as the ddI patent license?

11. What are the expected costs of the clinical trials needed to provide the FDA with sufficient evidence of the safety and efficacy of the therapy? If you don’t have an exact number, what is the range of costs you have used in doing the Section 209 analysis regarding the “proposed scope of exclusivity is not greater than reasonably necessary to provide the incentive for bringing the invention to practical application”?
