Example 7
For the determination of direct effects of chimeric NKG2D-bearing T cells (106) on the growth of RMA or RMA/Rae-1β tumors, chimeric NKG2D- or vector-transduced T cells were mixed with tumor cells (105) and then injected s.c. into the shaved right flank of recipient mice. Tumors were then measured using a caliper, and tumor areas were calculated. Animals were regarded as tumor-free when no tumor was found four weeks after inoculation. For the rechallenge experiments, mice were inoculated with 104 RMA cells on the shaved left flank. In other experiments, transduced T cells were injected intravenously the day before s.c. inoculation of tumor cells. Mice were monitored for tumor size every two days and were sacrificed when tumor burden became excessive.
Example 16
The antitumor activity of exemplary MEK inhibitor compounds is evaluated in vivo using human cell line derived xenografts (CDX) grown in immunodeficient mice. For these studies, AsPC1 (pancreatic cell line with KRAS G12D mutation), NCI-H2122 (lung cell line with KRAS G12C mutation), and 5637 (bladder cell line with CRAF amplification) models are used. In addition, HCT-116 (colorectal cell line with KRAS G13D mutation), SKM-1 (AML cell line with KRAS K117N mutation), and OCI-AML-3 (AML cell line with NRAS Q61L mutation) models are used. The tumor cell lines (AsPC-1, NCI-H2122, 5637, and HCT-116 cells) are maintained in vitro as monolayer culture in medium at 37° C. in an atmosphere of 5% CO2 in air. The tumor cell lines (SKM-1 and OCI-AML-3 cells) are maintained in vitro as a suspension in medium at 37° C. in an atmosphere of 5% CO2 in air. The tumor cells are routinely sub-cultured before confluence by trypsin-EDTA treatment, not to exceed 4-5 passages. The cells growing in an exponential growth phase are harvested for tumor inoculation. AsPC1, NCI-H2122, and OCI-AML-3 tumors are implanted into Balb/c nude mice. HCT-116 tumors are implanted into Nu/Nu mice. 5637 and SKM-1 tumors are implanted into NOG mice. Each mouse is inoculated subcutaneously on the right flank with tumor cells in a 1:1 mixture with matrigel. Tumors are allowed to grow to approximately 150-200 mm3. At this time, mice are assigned to groups such that the mean tumor volume is the same for each treatment group. The MEK inhibitor compound treatments are administrated to the tumor-bearing mice via oral gavage. Throughout the study, mouse body weight and tumor volume are recorded. The measurement of tumor size is conducted twice weekly with a caliper and recorded. The tumor volume (mm3) is estimated using the formula: TV=a×b2/2, where “a” and “b” are long and short diameters of a tumor, respectively.
In the AsPC-1 model, exemplary MEK inhibitor I-2 was treated at 3 mg/kg QD and a percent TGI (tumor growth inhibition) on Day 21 of 83.4% was observed. The average body weight gain observed on Day 21 was 2.4%.
In the NCI-H2122 model, exemplary MEK inhibitor 1-2 was treated at 3 mg/kg QD and a percent TGI on Day 31 of 104% was observed. The average body weight loss observed on Day 31 was 1.5%.
In the 5637 model, exemplary MEK inhibitor I-2 was treated at 3 mg/kg QD and a percent TGI on Day 21 of 111% was observed. The average body weight loss observed on Day 21 was 6.8%.
In the HCT-116 model, exemplary MEK inhibitor I-2 was treated at 2 mg/kg QD, 3 mg/kg QOD or 6 mg/kg QOD and a percent TGIs on Day 20 of 102.9%, 98.1%, and 98%, respectively, were observed. The average body weight gain observed on Day 20 was 4%, 5.5%, and 12.1%, respectively.
In the SKM-1 model, exemplary MEK inhibitor I-2 was treated at 1 mg/kg QD, 3 mg/kg QD or 6 mg/kg QOD and venetoclax was treated at 100 mg/kg QD and a percent TGIs on Day 22 of 97.7%, 98.4%, 96.2%, and 46.6% respectively, were observed. The average body weight loss observed on Day 22 for the 3 mg/kg QD group was 1.2%, whereas weight gain was observed in 1 mg/kg QD, 6 mg/kg QOD and venetoclax groups (1.2%, 3.9, and 7.5%, respectively).
In the OCI-AML-3 model, exemplary MEK inhibitor I-2 was treated at 1 mg/kg QD, 3 mg/kg QD or 6 mg/kg QOD, and venetoclax was treated at 100 mg/kg QD and a percent TGIs on Day 15 of 94.8, 98.6, 95.2, and 13% respectively, were observed. The average body weight loss observed on Day 15 for the 1 and 3 mg/kg QD group was 2.9% and 7.8%, respectively, whereas weight gain was observed in 6 mg/kg QOD and venetoclax groups (3.3% and 8.3%, respectively).
To study the expression of CD47 in response to DNA damage in tumor tissues, we used a syngeneic orthotropic mouse malignant mesothelioma (MM) disease model63 (link). 1×105 AB12 cells were injected to the peritoneum of BALB/c mice to generate tumors (>95% inoculation success rates). The resultant tumors are morphologically and histologically similar to human MM tumors, and respond to treatments used for MM patients, such as cisplatin. For cisplatin treatment a single injection of cisplatin (5 mg/kg) was given on day 3 following tumor inoculations, and tumor tissues were harvested from the peritoneum 6 days later.
