This page follows insider dealings at Protalix BioTherapeutics, Inc. as filed with SEC (Form 4), a company from the Healthcare & Pharma sector based in Israel. The group dates from 1993. Over the twelve months to 22 October 2026, 2 filings were filed, from 2 insiders.
Open-market activity splits into 1 purchase totalling €86k and 1 sale totalling €271; 1 insider sit on the buying side and 1 insider on the selling side. Purchases outweigh sales by €86k. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Biggest ticket of the year: €86k, bought by Bashan Dror and made public on 23 December 2025. Those buying include 1 chief executive.
For context, the typical company on the same exchange (median of 2,023 companies) published 41 filings over the same period, against 2 filings here. Over the whole record (from 2016), the tally stands at 8 purchases and 4 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 31 December 2025 lists revenue at 52.7 m USD and net income at -6.6 m USD.

Protalix BioTherapeutics, Inc. is a U.S.-listed biopharmaceutical company traded on NYSE American (NYSE/NASDAQ context) and incorporated in the United States, while its operating base and scientific footprint are primarily in Israel. For French-speaking investors, PLX is best understood as a niche rare-disease biotech focused on the discovery, development, production, and commercialization of recombinant therapeutic proteins. Its core differentiator is ProCellEx®, a proprietary plant cell-based protein expression platform that underpins both its commercial assets and its development pipeline.
From a strategic standpoint, Protalix has built its business around high-unmet-need rare diseases rather than broad primary-care markets. That approach generally implies smaller patient populations, higher scientific complexity, and meaningful regulatory hurdles, but it can also support premium pricing, orphan-drug economics, and stronger product differentiation if clinical and commercial execution is successful. The company’s lead commercial product is Elfabrio® (pegunigalsidase alfa), approved for adult patients with Fabry disease. Elfabrio is central to the company’s near-term revenue base and is commercialized through a partnership model, including Chiesi across key markets. This gives Protalix access to broader commercial reach while limiting the need to build a fully integrated global sales infrastructure on its own.
Another important historical asset is taliglucerase alfa, Protalix’s first product manufactured using ProCellEx, for Gaucher disease. Protalix licensed worldwide development and commercialization rights to Pfizer, except in Brazil where Protalix retains full rights. That partnership remains strategically relevant because it validates the platform and provides an additional, albeit selective, revenue opportunity. Beyond marketed products, the pipeline includes PRX-115, a plant cell-expressed recombinant PEGylated uricase being developed for uncontrolled gout, and PRX-119, a long-acting DNase I candidate aimed at NETs-related diseases. In other words, the company is trying to extend a single manufacturing and biology platform across multiple specialty indications.
Competitively, Protalix does not operate as a large-cap pharma company; it competes with better-financed biotech and pharmaceutical peers, but seeks to offset that disadvantage through technological specialization, focused indication selection, and strategic partnerships. Its geographic presence is notable: the company is a U.S. public issuer, yet its operational narrative is closely tied to Israel. Recent milestones are important for investors: 2025 filings and press releases highlighted stronger revenue momentum, an IND submission for PRX-115 in October 2025, and inclusion in the Russell 3000 and Russell 2000 indexes in June 2025. Overall, PLX is a specialized rare-disease biotech with a credible platform story, a commercial product in Fabry disease, and a pipeline that offers upside but remains subject to the execution, clinical, regulatory, and partnership risks typical of the sector.
