Estrella Immunopharma Stock Price, News & Analysis

Estrella Immunopharma, Inc. (NASDAQ: ESLA, ESLAW) is a clinical-stage biopharmaceutical company in the biotechnology and healthcare sector. The company focuses on developing CD19- and CD22-targeted ARTEMIS® T‑cell therapies intended to treat cancers and autoimmune diseases. Estrella describes its mission as harnessing the evolutionary power of the human immune system to transform the lives of patients fighting cancer and other diseases.

Estrella’s research and development efforts center on its ARTEMIS® T‑cell engineering platform, which is licensed from Eureka Therapeutics, Inc., identified as Estrella’s parent company. The platform is designed so that ARTEMIS T‑cells are activated and regulated upon engagement with cancer targets using cellular mechanisms that more closely resemble those of endogenous T‑cell receptors. According to the company, this design is intended to produce a more natural and regulated immune response compared with traditional CAR‑T cells.

Lead product candidate: EB103

Estrella’s lead product candidate, EB103, is described as a CD19‑Redirected ARTEMIS® T‑cell therapy. EB103 utilizes Eureka’s ARTEMIS technology to target CD19, a protein expressed on the surface of almost all B‑cell leukemias and lymphomas. Once infused, EB103 T‑cells are designed to seek out CD19‑positive cancer cells, bind to these cells, and destroy them.

EB103 is being evaluated in the STARLIGHT‑1 Phase I/II clinical trial, an open‑label, dose‑escalation, multi‑center study in adult patients with relapsed or refractory B‑cell non‑Hodgkin lymphoma (NHL) who have failed multiple prior lines of therapy. The trial is described as using a standard 3+3 dose‑escalation design, with objectives that include assessing safety and tolerability, characterizing pharmacokinetics of EB103, and determining the Recommended Phase II Dose (RP2D). The study includes a dose‑escalation phase followed by an expansion phase.

In the first dose cohort of STARLIGHT‑1, Estrella reported that patients with relapsed/refractory B‑cell NHL showed a favorable safety profile, with no dose‑limiting toxicities or treatment‑related serious adverse events observed in the preliminary data reviewed by the Data and Safety Monitoring Board. Tumor responses were noted in all patients at Month 1 in that cohort. In a separate update, the company reported that the first patient treated in STARLIGHT‑1 achieved a complete response one month after receiving EB103, with no treatment‑related serious adverse events reported in that case.

Pipeline candidate: EB104

In addition to EB103, Estrella is developing EB104, which also utilizes the ARTEMIS technology. EB104 is designed to target both CD19 and CD22, proteins that are described as being expressed on the surface of most B‑cell malignancies. By targeting both antigens, EB104 is positioned within Estrella’s pipeline as another ARTEMIS‑based T‑cell therapy candidate for B‑cell cancers, although detailed clinical trial information for EB104 is not provided in the available materials.

Clinical focus: B‑cell malignancies and autoimmune diseases

Across its communications, Estrella consistently characterizes itself as focusing on cancers and autoimmune diseases, with a particular emphasis on B‑cell leukemias and lymphomas. The company highlights relapsed or refractory and high‑risk blood cancers, including B‑cell non‑Hodgkin lymphoma, as key areas of clinical investigation for EB103. Estrella also notes interest in exploring the potential of ARTEMIS T‑cell therapy in other indications, including solid tumors and autoimmune conditions, while emphasizing its current status as a clinical‑stage company.

Capital markets and securities

Estrella’s common stock and warrants trade on Nasdaq under the symbols ESLA and ESLAW, respectively. The company has used capital markets transactions to support its operations. In one registered direct offering with a single healthcare‑focused institutional investor, together with a concurrent private placement, Estrella issued shares of common stock, pre‑funded warrants, and common warrants. The company stated that the aggregate gross proceeds from these transactions were approximately $8.0 million and that it expects to use the net proceeds, together with existing cash, for general corporate purposes and working capital.

The registered direct offering was conducted under a shelf registration statement on Form S‑3 that was declared effective by the U.S. Securities and Exchange Commission. The common warrants issued in the concurrent private placement were offered in a transaction not involving a public offering and were not registered under the Securities Act of 1933 at the time of the announcement. Estrella entered into a registration rights agreement with the investor, under which it agreed to file one or more registration statements covering the resale of the shares of common stock issuable upon exercise of the common warrants.
