Definitions
- Interleukin 6 is an interleukin that acts as both a pro-inflammatory cytokine and an anti-inflammatory myokine.
- IL-6 is secreted by T cells and macrophages to stimulate immune response, normally for infections and tissue damage such as burns.
- IL-6 meditated signaling also stimulates inflammatory and auto-immune processes in many diseases, such as diabetes, atherosclerosis, depression, lupus, rheumatoid arthritis, and/or a wide range of cancers. Secretion of IL-6 by cancer cells is believed to promote tumor growth.
- the protein complex associates with the transmembrane protein glycoprotein 130 (gp130 or IL- 6 ⁇ ) to induce cellular signaling.
- Programmed death ligand 1 is a transmembrane protein that is involved with suppressing the immune system. Normally, the human immune system reacts to antigens by upregulating the proliferation of CD8+ T cells specific to those antigens. When PD-L1 binds to the PD-1 receptor on activated T and B cells, an inhibitory signal is produced, which both reduces the proliferation of the antigen specific CD8+ T cells and also induces apoptosis in currently activated cells.
- PD-L1 signaling is involved in disease states, such as cancer (where upregulation of PD-L1 by tumors may allow the tumor to evade the host immune system and enjoy aggressive growth) and infection (where pathogen-induced up-regulation of PD-L1 may allow pathogens to sequester host immune response during both acute and chronic infection).
- cancer where upregulation of PD-L1 by tumors may allow the tumor to evade the host immune system and enjoy aggressive growth
- infection where pathogen-induced up-regulation of PD-L1 may allow pathogens to sequester host immune response during both acute and chronic infection.
- IL-6 and PD-L1 have been implicated in a variety of disorders, several therapeutic strategies have been designed to inhibit IL-6 and/or PD-L1 activity.
- Murine, chimeric, and other non-human anti-IL-6, anti-PD-1, and/or anti-PD-L1 antibodies have been developed. However, they may be limited in their potency, effectiveness, may often trigger an unacceptable immune response (i.e., immunogenicity) and/or require a high dosage (See, Trikha et al., 2003, Clin. Can. Res.9:4653-4665, herein incorporated by reference in its entirety). For example, antibodies containing non-human portions often give rise to an immune response in humans.

- Example 1 Reduction in IL-6 protein levels by RNAi of Sigma1
- RNA interference RNA interference
- Protein lysates were prepared from MDA-468 cells.10 cm plates were seeded to 50-60% confluent the day before the transfection.32 ⁇ L of Sigma1 siRNA + 600 ⁇ L OPTIMEM were combined, mixed through pipetting and incubated 10 minutes at room temperature (RT). During the 10 minute incubation, media was replaced in plate with 10 mL fresh media. To that tube of siRNA and OPTIMEM, 35 ⁇ L of interferin were added, and the system was vortexed immediately for 20 seconds, and incubated for 20 minutes at RT. The entire volume was added to the plate. The system was incubated for 2 days. On third day, plates were split so that cells were 50-60% confluent. On the following day, the procedure was repeated with a second Sigma1 SiRNA transfection. After the next 2 days, the cells were harvested, lysed, and run on gel to confirm Sigma1 knockdown.
- Cells were rinsed with Ca/Mg-free PBS and detached using 2 mM EDTA in Ca/Mg-free PBS. Cells were spun for 4 minutes at 14,000 rpm at 4 °C. PBS was aspirated and pellets were re-spun. Pellets were snap-frozen on dry ice. The pellets were lysed using RIPA + 10% glycerol + Protease inhibitor cocktail + Phosphatase inhibitor cocktail + EDTA. Lysis consisted of pipetting up and down 20 times, rotating the tubes at 4 °C for 30 minutes then centrifuged for 15 minutes at 14,000 rpm at 4 °C. The lysates were aliquoted into 30 ⁇ L volumes and stored at -80 °C.
- Anti-Rabbit HRP was used as a secondary antibody (Cell Signaling 70741:2000 in 5% non-fat dry milk in TBST) and HRP-beta actin was used as a loading control (Cell Signaling 47778, 2:1000 in 5% non-fat dry milk in TBST). Protein levels were measured using ImageJ, IL-6 expression was normalized to beta actin.
- RNAi of Sigma1 reduced levels of IL-6 but not the control beta-actin.
- FIG.1A the protein bands for IL-6, beta-actin, and Sigma1 are illustrated. The left column is the control RNAi, while the right column used the Sigma1 RNAi construct.
- both Sigma1 and IL-6 expression levels were reduced, while the beta-actin expression levels remained unchanged.
- the decrease in levels of the IL-6 protein shown in FIG.1A is quantitated in FIG.1B.
- the control expression levels of IL-6 were set to 1.0.
- the RNAi of Sigma1 reduced IL-6 expression to about 0.45. This demonstrates that the modulation of Sigma1 can be used to control the expression of IL-6, which can be used to treat various disorders as described herein.

- Anti-rabbit HRP was used as a secondary antibody (Cell Signaling 70741:2000 in 5% non-fat dry milk in TBST). Vinculin was used as a loading control (Sigma Aldrich V91311:1000 in 5% non-fat dry milk in TBST) with anti-mouse HRP as a secondary (Cell Signaling 70761:2000 in 5% non-fat dry milk in TBST). Protein levels were measured using ImageJ, PD-L1 expression was normalized to Vinculin.
- the Jurkat NFAT Luciferase Assay utilized the Promega PD1/PD-L1 Blockade Assay Kit (CS187111).10,000 PC3 cells/well were plated on Wallac B&W 96-well Isoplate (with white wells and bottom and black matrix) in complete culture medium, i.e., RPMI-1640 supplemented with 5% fetal bovine serum (FBS). The next day, PC3 cells were treated with 10 ⁇ M IPAG for 16 hours. After 16 hour treatment, the IPAG containing culture medium was removed and treated PC3 cells were washed with complete medium. Subsequently, 10,000 Jurkat (NFAT-luciferase) cells were added to wells in complete culture medium. Six hours later, Promega Bio-Glo reagent was added to each well. After 5 minutes, the plate was read with a GloMax plate reader.

- both Sigma1 and PD-L1 expression levels were reduced, while the beta-actin expression levels remained unchanged.
- the decrease in levels of the PD-L1 protein shown in FIG.3A is quantitated in FIG.3B.
- the control expression levels of PD-L1 were set to 1.0.
- the RNAi of Sigma1 reduced PD-L1 expression to about 0.36. This demonstrates that the modulation of Sigma1 can be used to control the expression of PD-L1, which can be used to treat various disorders as described herein.
- Example 4 Reduction in PD-L1 expression in breast cancer cells by administration of Sigma1 modulator
- Sigma1 protein was inhibited by the Sigma1 inhibitor 1-(4-iodo phenyl)-3-(2-adamantyl)guanidine (IPAG) or activated by the Sigma1 agonist 1-[2-(3,4- Dimethoxyphenyl)ethyl]-4-(3-phenylpropyl)-piperazine dihydrochloride (SA4503), and then levels of PD-L1 were measured to determine if a lower expression levels of Sigma1 resulted in lower expression of PD-L1.
- MDA231 triple negative breast cancer cells that are PD-L1 positive were treated with 10 ⁇ M of IPAG, 20 ⁇ M of SA4503, or the combination of both for 16 hours.
- MDA231 cells were seeded 24h prior to treatment with dimethyl sulfoxide (DMSO) or 10 ⁇ M IPAG, 20 ⁇ M of SA4503, or the combination of both for 16h.
- DMSO dimethyl sulfoxide
- IPAG reduced levels of PD-L1 but not control Vinculin, and the Sigma1 agonist SA4503 reversed IPAG-mediated PD-L1 inhibition. Together, this indicates that IPAG inhibition of PD-L1 is Sigma1-dependent.
- FIG.4A the protein bands for PD-L1 and the control Vinculin are shown. The left column is the control treatment (DMSO), while the right columns are the 10 ⁇ M IPAG treatment, followed by 20 ⁇ M of SA4503 or the combination of both. IPAG greatly reduces expression of PD-L1, but not the control. IPAG-mediated PD-L1 inhibition is reversed by the addition of SA4503. The decrease in expression of the PD-L1 protein is quantitated in FIG.4B.
- the control expression levels of PD-L1 are set to 1.0.
- the exposure to IPAG reduced PD-L1 expression to approximately 0.5.
- the exposure to IPAG plus SA4503 increased PD-L1 expression to approximately 1.35, indicating that a Sigma1 agonist (SA4503) can reverse PD-L1 inhibition by a Sigma1 inhibitor (IPAG).
- SA4503 a Sigma1 agonist
- IPG Sigma1 inhibitor
- Example 5 Reduction in tumor growth in PD-L1-dependent breast caner cells by administration of Sigma1 modulator.
- Sigma1 protein was inhibited by the Sigma1 inhibitor, Compound G, and then tumor growth inhibition was measured to determine if Sigma1 inhibition delayed tumor growth in a PD-L1 positive triple negative breast cancer cell line (MDA231).
- MDA-MB-231 human breast carcinoma cell lines were obtained from the American Type Culture Collection (Manassas, VA) and maintained according to the supplier’s instructions. Cells were harvested at the exponential phase of growth for injection into the mammary fat pads of mice. NOD scid (NOD/SCID) and BalBC mice were purchased from Jackson Laboratory. Eight week old female mice were injected unilaterally with 2.5 ⁇ 10 6 cells in 200 ⁇ L of 50:50
- DMSO DMSO
- Compound G drug
- Compound G inhibited tumor growth in BalbC and not NOD/SCID mice, indicating that Sigma1 inhibition requires mice to have an intact immune system (BalbC) to stimulate an anti-tumor response through PD-L1 downregulation.
- FIG.5 tumor growth inhibition in immune-competent mice (BalbC) are shown on the left while tumor growth inhibition in immune-deficient mice (NOD/SCID) are shown on the left.
- Mice were treated with either control (DMSO) or 30 mg/kg of Compound G.
- Compound G greatly reduced tumor growth in immune-competent mice, indicating that Sigma1 inhibition of PD-L1 results in potent anti-tumor immune activity.
- a pharmaceutical composition described in Example 2 and the PD-L1 inhibitor atezolizumab (MPDL3280A) are administered to human non-small cell lung cancer (NSCLC) patients orally in combination with chemotherapy.
- NSCLC non-small cell lung cancer
- Patients are monitored for tumor regression as well as levels of IL-6 and PD-L1 expression in whole blood and tumor biopsies.
- Patients are given the treatment combination for standard treatment cycles 4-6 cycles. After 6 months from start of the treatment, the tumors in patients receiving the combination treatment are measured and/or evaluated.
- the combination therapy shrinks tumors in the majority of patients. Levels of IL-6 and/or PD-L1 are decreased after administration of the combination.
- Example 7 Combination of Compound used in Example 2 and anti-PD-1 antibodies shrink tumor size in lung cancer patients and increase survival in lung cancer patients

- NSCLC non-small cell lung cancer
- the patients are previously treated with chemotherapy, or not previously treated with chemotherapy.
- Patients are monitored for tumor regression and survival. Tumor size and median survival are evaluated in the patients. Tumors are found to have been reduced in size as compared to a regimen without the compound of Example 2.
- the median survival increases as compared to a regimen without the compound of Example 2. as compared to a regimen without the compound of Example 2, this result is replicated regardless of the anti-PD-1 antibody that is used.
