Presentation given by Vicenç Tur from Lipopharma Therapeutics in the framework of the Emergence Forum Barcelona Biocat organized the Barcelona Emergence Forum (April 10-11th, 2014, Congress Palace, Montjuïc) supported by the TRANSBIO SUDOE, a translational cooperation project dedicated to innovation in life sciences in South-West Europe. The Barcelona Emergence Forum contributed to bringing together Academics, Companies, Investment Entities, Technology Platforms and Technology Transfer Offices from Spain, France and Portugal to set up collaborative projects on Human Health & Agro-food Innovation.

company based in Palma de Mallorca (Spain) that focuses on the
discovery, rational design and development of next generation medicinesnext generation medicines
associated with a novel breakthrough therapeutic approach:
the Membrane Lipid TherapyMembrane Lipid Therapy (MLT)

1. Based on an disruptive Technology platform: Membrane Lipid TherapyMembrane Lipid Therapy ((MLTMLT))
2. Game-changing novel MOAnovel MOA: SMS activation → regulation of membrane lipids
→ Multi-pathway modulation
3. Highly specific to cancer cells; very high efficacy in glioma (in cells & animals).
Non Toxic. Crosses the BBB.
4. ORAL formulation. Simple Chemistry. Stable at ambient for +24 months

Effect of SMS1 genetic alterations on glioma patients’ survival
(Differential SGMS1 Gene Expression & Copy Number Analysis for SGMS1)
National Cancer Institute. 2005. REMBRANDT <http://rembrandt.nci.nih.gov>. Accessed October 2012
SGSM1 up-regulated (n = 1)
SGMS1 Intermediate (n = 258)
All Glioma average (n=454)
SGSM1 down-regulated (n = 84)
Left panel: down-regulation of SGMS1 (green line) is associated with a marked and significant (P = 2 x 10-10) reduction in the
life-span of glioma patients.
SGSM1 Amplified (n = 73)
All Glioma average (n=454)
SGSM1 Deleted (n = 278)
Right panel: deletion of the SGMS1 gene (green line) occurs in about 61% of all glioma patients and is associated with a
significant reduction in their life-span, whereas patients with more than 2 copies of the SGMS1 gene (red line) have an
increased life span and ca. 25% probability to live over 20 years.

Minerval regulates Ras localization in GLIOMA (SF767) cells
Translocation of K-Ras (green) from the membrane to the cytosol and inner membranes after incubations of 10 minutes (1) or 24
hours (2). Ph. C.: phase contrast micrography. Increase in green fluorescence (K-Ras) after 10-minute incubations in the presence of
Minerval does not correspond to increases in the expression of this protein. Proteins in the MAPK signalling pathway present a
reduction in their activity, as measured by its phosphorilation status, while the expression of this proteins is not altered.

PI/II Clinical Study with Minerval
MIN-001-1203: “A phase I/IIa open-label dose escalation study of Minerval
in subjects with advanced solid tumors including malignant glioma”
Top leading European KOL and investigational sites involved: Johann de
Bono (Royal Marsden Hospital, London), Roger Stupp (University Hospital,
Zurich), Jordi Rodon (Vall d'Hebron Institute of Oncology, Barcelona), Ruth
Plummer (NCCC, Freeman Hospital, Newcastle)
Part A. Dose escalating study. Up to 30 patients. 21-day treatments. Glioma
and other solid tumors (lung, pancreas…)
Part B. Exploratory study. Up to 20 patients in two groups. 21-day
treatments. 1st group with glioma patients. 2nd group with biopsiable solid-
tumors patients for biomarker evaluation.

2) GFAPGFAP → cancer cell differentiation [glioma] >>> in plasma samples
3) DHFRDHFR → cell proliferation [All cancers] >>> in tumor samples
4) miRNAmiRNA → diagnostic, response, pt segmentation [glioma, solid tumours]

Marked and significant reduction in several miRNA have been observed after analysis of plasma samples
from nude mice inoculated with human lung cancer (A549) and glioma (SF767) cells. Treatment with
Minerval (4 weeks) induced a significant recovery of miRNA levels.
