Recepta Biopharma is a Brazilian biotechnology company headquartered in São Paulo, Brazil, focused on developing antibody-based immunotherapeutics for oncology and neurodegenerative diseases. Founded in 2008, the company has expanded from its original oncology focus to include significant research and development programs targeting [neuroinflammatory pathways](/mechanisms/neuroinflammation) associated with [Alzheimer's disease](/diseases/alzheimers-disease) (AD) and [Parkinson's disease](/diseases/parkinsons-disease) (PD)[@recepta2024]. Recepta represents one of the leading biotechnology companies in Brazil's growing biopharmaceutical sector, contributing to the country's emerging strength in antibody therapeutics and neuroscience research["@brazil biotech"].
The company's mission centers on developing innovative biological therapies that address unmet medical needs in diseases with limited treatment options. Within the neuroscience domain, Recepta has established programs targeting neuroinflammation—a central pathological feature shared by both Alzheimer's and Parkinson's diseases—through novel monoclonal antibody approaches["@martins2023"]. The company's antibody engineering capabilities, developed over more than a decade of operation, provide the technological foundation for these neurodegenerative disease programs["@recepta pipeline"].
Recepta Biopharma was established in 2008 in São Paulo, Brazil, with an initial focus on developing antibody-based cancer therapeutics. The company's founding reflected the growing interest in Brazil's biotechnology sector during the late 2000s, as the country sought to develop domestic capabilities in innovative drug development rather than relying primarily on imported pharmaceuticals[@brazil biotech].
Since its founding, Recepta has evolved significantly:

The company's early success in oncology provided financial stability and demonstrated capability in antibody development, enabling expansion into neuroscience research programs in the mid-2010s[@recepta2024].
Recepta operates within Brazil's emerging biotechnology ecosystem, which has grown substantially since the company's founding. Brazil's biopharmaceutical sector has attracted increasing investment and government support, with programs like the Brazilian Industrial Biotechnology Policy encouraging development of domestic innovative drug development capabilities[@brazil biotech].
Key features of the Brazilian biotechnology environment relevant to Recepta's operations include:
Recepta's neuroscience programs focus on targeting [neuroinflammation](/mechanisms/neuroinflammation), a common pathological mechanism underlying both [Alzheimer's disease](/diseases/alzheimers-disease) and [Parkinson's disease](/diseases/parkinsons-disease)[@henriquez2023]. The company leverages its antibody development expertise to create therapeutic antibodies that modulate inflammatory pathways in the central nervous system.
Neuroinflammation has emerged as a critical component of Alzheimer's disease pathophysiology, with mounting evidence indicating that chronic inflammatory processes contribute to disease progression[@lyman2020]. Microglia—the brain's resident immune cells—play a central role in this process, becoming persistently activated in response to amyloid-beta plaques and tau pathology. This chronic activation creates a self-perpetuating cycle of inflammation that accelerates neuronal damage[@ulrich2016].
Recepta's Alzheimer's program targets this neuroinflammatory axis through several approaches:
The RGT-100 program represents Recepta's most advanced Alzheimer's candidate, currently in preclinical development:
| Program | Target | Stage | Indication |
|---------|--------|-------|------------|
| RGT-100 | IL-6/IL-6R | Preclinical | Alzheimer's disease |
| RGT-200 | Tau oligomers | Discovery | Alzheimer's disease |
| RGT-300 | Neuroinflammation | Discovery | Parkinson's disease |
Mechanism of Action:
RGT-100 is a monoclonal antibody designed to bind and neutralize interleukin-6 (IL-6) and its receptor (IL-6R). IL-6 is a pleiotropic cytokine that plays complex roles in brain physiology but becomes pathogenic when chronically elevated. In AD, IL-6 contributes to:
Development Status:
The RGT-200 program targets toxic tau oligomers, representing a complementary approach to anti-amyloid strategies:
Tau Pathology in Alzheimer's Disease:
Tau protein forms neurofibrillary tangles in Alzheimer's disease, and the spread of tau pathology correlates with cognitive decline. While tau tangles have been studied extensively, recent research indicates that soluble tau oligomers may be the most toxic species, preceding and driving the formation of insoluble tangles[@zuroff2020].
RGT-200 Approach:
[Parkinson's disease](/diseases/parkinsons-disease) involves multiple pathological mechanisms, including [dopaminergic](/cell-types/dopaminergic-neurons) neuron loss, [alpha-synuclein](/proteins/alpha-synuclein) aggregation, and [neuroinflammation](/mechanisms/neuroinflammation). [Microglial activation](/cell-types/microglia) is prominent in PD brains and contributes to disease progression through release of pro-inflammatory cytokines and reactive oxygen species[@ivanova2022].
Recepta's RGT-300 program focuses on modulating neuroinflammatory pathways in Parkinson's disease, potentially complementing disease-modifying approaches targeting [alpha-synuclein](/proteins/alpha-synuclein).
Target: Neuroinflammation in Parkinson's disease
Approach: The program aims to develop antibodies that modulate microglial activation states, shifting from the pro-inflammatory M1 phenotype toward the more beneficial M2 phenotype associated with tissue repair.
Research Status: Discovery stage, with target identification and antibody screening ongoing.
Recepta has developed comprehensive antibody engineering capabilities that support both its oncology and neuroscience programs:
Therapeutic antibodies derived from non-human sources (typically mice) require humanization to reduce immunogenicity in humans. Recepta employs:
For enhanced therapeutic potency, Recepta improves antibody binding affinity through:
The antibody Fc region mediates effector functions and influences therapeutic properties:
Recepta has developed capabilities in bispecific antibody engineering, enabling single antibodies to target two different antigens:
One of the most significant challenges in developing therapeutics for neurodegenerative diseases is achieving adequate drug concentrations in the brain. Recepta is pursuing multiple strategies to address this challenge[@parhiz2020]:
This approach exploits endogenous transport mechanisms that allow certain molecules to cross the blood-brain barrier:
Temporary disruption of the blood-brain barrier to enhance therapeutic antibody penetration:
For certain programs, Recepta is exploring direct CNS delivery:

The company's neuroscience programs represent a significant investment in addressing the growing burden of neurodegenerative diseases in Brazil and globally.
The [Alzheimer's disease](/diseases/alzheimers-disease) market represents one of the largest unmet medical needs in pharmaceutical development:
The [Parkinson's disease](/diseases/parkinsons-disease) market similarly presents substantial opportunity:
The role of [neuroinflammation](/mechanisms/neuroinflammation) in [Alzheimer's disease](/diseases/alzheimers-disease) has evolved from being considered a secondary phenomenon to a central pathological mechanism:
Microglial Activation:
[Microglia](/cell-types/microglia) are the brain's resident immune cells and play essential roles in brain homeostasis and defense. In AD, microglia become chronically activated in response to [amyloid-beta](/proteins/amyloid-beta) plaques, producing pro-inflammatory cytokines that contribute to [synaptic dysfunction](/mechanisms/synaptic-dysfunction) and neuronal death[@lyman2020]. This creates a feedforward loop where inflammation promotes more amyloid processing and [tau pathology](/mechanisms/tauopathies), which in turn triggers additional microglial activation.
Cytokine Networks:
Multiple cytokines contribute to neuroinflammation in AD:
Neuroinflammation is similarly prominent in [Parkinson's disease](/diseases/parkinsons-disease):
Microglial Activation in PD:
Post-mortem studies consistently show increased [microglial](/cell-types/microglia) activation in PD brains, particularly in regions with [dopaminergic](/cell-types/dopaminergic-neurons) neuron loss. PET studies using TSPO ligands have confirmed microglial activation in living PD patients.
Inflammatory Pathways:
Multiple pathways contribute to neuroinflammation in PD:
