01Mechanism of Action

Parameter
Ovagen
VIP
Primary target
Ovarian tissue chromatin complexes
VPAC1 and VPAC2 G-protein-coupled receptorsUdupa 2025
Pathway
Tissue-specific peptide → Nuclear chromatin binding → Gene expression modulation → Cellular differentiation
VIP → VPAC1/VPAC2 activation → cAMP elevation → Pulmonary vasodilation + epithelial protection
Downstream effect
Proposed ovarian functional support, fertility regulation, hormonal homeostasis restoration
Anti-inflammatory cytokine modulation, alveolar-capillary membrane stabilization, pulmonary smooth muscle relaxation, reduced neutrophil infiltration
Feedback intact?
Presumed physiological — Khavinson peptides described as regulatory, not replacement
Yes — exogenous VIP acts as physiological agonist
Origin
Extracted from bovine/porcine ovarian tissue; short synthetic peptides (2–4 amino acids)
Endogenous 28-amino-acid neuropeptide; synthetic analogue (aviptadil) identical to natural VIP
Antibody development

02Dosage Protocols

Parameter
Ovagen
VIP
Standard dose
10–20 mg / day (oral) or 1–2 mg SQ
Extrapolated from Khavinson-school protocols; no ovagen-specific PubMed dose studies.
Frequency
Once daily or cyclical (10–20 days per month)
Cyclical protocols common in Khavinson bioregulator tradition.
Evidence basis
Theoretical / Russian-tradition
Phase 3 RCT (TESICO)Brown 2023
816-patient randomized controlled trial in COVID-19 ARDS.
Duration
4–12 weeks per cycle
Khavinson protocols typically 1–3 months; repeat cycles as needed.
Route
Oral (capsule) or subcutaneous
Oral absorption assumed for short peptides; SQ route mirrors other Khavinson bioregulators.
Intravenous (ARDS protocol)
60–90 mcg/kg/day via continuous infusion
TESICO trial protocol for COVID-19 ARDS.
Infusion duration
12-hour continuous IV infusion dailyBrown 2023
Inhaled (investigational)
Variable dosing under clinical trial protocolsBoesing 2022
Delivered via nebulizer for direct pulmonary deposition.
Treatment duration
3–14 days (acute ARDS)
Reconstitution
Lyophilized powder reconstituted with sterile diluent per protocol
Half-life
~2 minutes (plasma)
Rapid clearance necessitates continuous infusion.

04Side Effects & Safety

Parameter
Ovagen
VIP
Reported adverse events
None documented in indexed literature
Theoretical hormonal effects
Ovarian stimulation — monitor for estrogen-sensitive conditions
Injection site reaction
Possible mild erythema (SQ route)
Long-term safety
Unknown — no PubMed-indexed RCTs
Hypotension
Transient vasodilation-related blood pressure drop
Tachycardia
Reflex tachycardia secondary to vasodilation
Infusion site reactions
Erythema, phlebitis (IV administration)
GI symptoms
Nausea, diarrhea (VIP is endogenous GI peptide)
Overall tolerability
Well-tolerated in Phase 3 trials; adverse event profile comparable to placebo
Absolute Contraindications
Ovagen
  • ·Active hormone-sensitive malignancy (breast, ovarian, endometrial)
  • ·Pregnancy
VIP
  • ·Known hypersensitivity to aviptadil or formulation components
Relative Contraindications
Ovagen
  • ·History of estrogen-sensitive tumors (monitor)
  • ·Polycystic ovary syndrome (PCOS) — theoretical ovarian hyperstimulation risk
  • ·Endometriosis or fibroids (estrogen-responsive conditions)
VIP
  • ·Severe hypotension or shock states (monitor blood pressure)
  • ·Pregnancy — insufficient safety data

05Administration Protocol

Parameter
Ovagen
VIP
1. Oral route
Typical dose: 10–20 mg once daily. Capsule form — taken on empty stomach, 20–30 min before meals. Khavinson tradition suggests morning administration.
Reconstitute lyophilized aviptadil powder with sterile diluent per manufacturer protocol. Inspect solution for particulates — should be clear and colorless.
2. Subcutaneous route
1–2 mg per injection. Reconstitute lyophilised powder with sterile water if required. Inject into abdomen or thigh; rotate sites.
Administer as continuous 12-hour intravenous infusion via central or peripheral line. Use infusion pump for precise dosing (60–90 mcg/kg/day divided over infusion duration).
3. Cyclical protocol
Common pattern: 10–20 days on, 10 days off. Aligns with menstrual cycle phases in some protocols. Repeat cycles for 2–3 months, then assess.
Monitor blood pressure, heart rate, and oxygenation continuously during first infusion. Assess for hypotension and adjust infusion rate if needed.
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within 7–14 days.
Deliver via jet or mesh nebulizer per clinical trial protocol. Patient seated upright, normal tidal breathing for 10–15 minutes.
5. Storage
Store lyophilized powder at 2–8 °C, light-protected. Reconstituted solution: use immediately or within 24 hours if refrigerated.
