Problems solved by technology

Consequently, reports in the literature are often contradictory, and it remains unclear whether glucocorticoid signaling has an effect on cancer, and whether this effect may be a positive or negative one
[0006] Therefore, there is a need for improved treatments for cancerous tumors, including cervical cancer, given the lack of good treatment options for many cancer patients

Embodiment 1

[0226] Embodiment 1.HepG2 tyrosine aminotransferase (TAT) test

[0227] The following protocol describes the assay used to measure TAT induction by dexamethasone in HepG2 cells (a human hepatocellular carcinoma cell line; ECACC, UK). At 37°C, 5% / 95% (v / v) CO 2 HepG2 cells were cultured in MEME medium supplemented with 10% (v / v) fetal calf serum, 2 mM L-glutamine and 1% (v / v) NEAA under / air. Then, HepG2 cells were counted and adjusted to produce 0.125×10 6 cells / ml and seeded at 25,000 cells / well in 200 μl in 96-well, sterile tissue culture microtiter plates, followed by incubation at 37°C, 5% CO 2 Incubate for 24 hours.

[0228] Then, the growth medium was removed and replaced with test medium {RPMI 1640, no phenol red, 2 mM L-glutamine + 10 μΜ forskolin}. Test compounds were then screened against 100 nM dexamethasone challenge. Compounds were then serially half-log diluted from 10 mM stocks into 100% (v / v) dimethyl sulfoxide. Then, an 8-point semi-log dilution curve wa...

Embodiment 2

[0232] Example 2. Reduction of implanted cervical cancer tumor growth in mice using CORT125134 and paclitaxel combination therapy

[0233] A suspension of human HeLa cervical cancer cells was injected subcutaneously into the right flank of 5-6 week old immunosuppressed female mice (BALB / c nude) at 5 million cells per mouse. Tumors are allowed to grow until they reach 100-200mm 3 volume of. The mice were then divided into five groups of ten (10) each. Group 1 was given paclitaxel vehicle (sterile saline) intravenously (i.v.) every 4 days, and CORT125134 vehicle (10% DMSO, 0.1% Tween 80 and 89.9% HPMC (0.5% ), 10ml / kg). Group 2 received paclitaxel (7.5 mg / kg) intravenously every 4 days. Group 3 was administered paclitaxel intravenously every 4 days, and CORT125134 (30 mg / kg) was orally administered the day before and on the day of paclitaxel administration. Group 4 received paclitaxel (15 mg / kg) intravenously every 4 days. Group 5 was administered paclitaxel (15 mg / kg) int...

Embodiment 3

[0239] Example 3. Treatment of Ovarian Cancer Explants with CORT125134 in Combination with Gemcitabine / Carboplatin

[0240] The effect of CORT125134 in combination with gemcitabine / carboplatin in a mouse xenograft model of ovarian cancer was shown in image 3 In , the results are presented for 10 mice per group. CORT 125134 was administered intraperitoneally (i.p.) on days 43, 44, 50, and 51, and gemcitabine / carboplatin was administered intraperitoneally on days 44 and 51. Data represent mean values. SK-OV-3 cells (5 million cells per mouse) were injected into the right flank of female Balb / c nude mice. When the tumor reaches 200mm 3 When the volume was , the mice were randomly divided into 10 / group and the treatment was started. Mice were treated as follows: group 1 received vehicle on dosing days 1, 2, 8 and 9, group 2 received gemcitabine (80 mg / kg i.p.) and carboplatin on dosing days 2 and 9 (15mg / kg i.p.), group 3 received gemcitabine / carboplatin + CORT125134 (20mg / k...

Abstract

Methods for treating a subject having a cancerous tumor are disclosed. The methods comprise administering to the subject an effective amount of a non-steroidal selective glucocorticoid receptor modulator (SGRM) and an effective amount of a chemotherapeutic agent. The tumor may be cervical cancer. The SGRM may be a fused azadecalin. In embodiments, the SGRM may be a heteroaryl ketone fused azadecalin or an octahydro fused azadecalin.

Description

Background technique [0001] Cancer is the leading cause of death in the United States. For example, cervical cancer often has a poor prognosis even when diagnosed early, and signs and symptoms may not appear until the cancer is very advanced and complete surgical removal becomes impossible. [0002] Conventional treatment options for cancers such as cervical cancer include surgery, radiation therapy, and chemotherapy. Not all cancers, and not all cervical cancers, are resectable when diagnosed. Tumors such as cervical cancer tumors that are at an advanced stage usually require radiation therapy or chemotherapy for treatment. [0003] Radiation therapy requires maximum exposure of the affected tissue while sparing normal surrounding tissue. Interstitial therapy, in which needles containing radioactive sources are embedded in tumors, has emerged as a valuable new approach. In this way, large doses of radiation can be delivered locally without harming surrounding normal struc...
