Thank you, Grace, and thank you, everyone, for joining us today for our first quarter 2024 business update. As previously reported, we have closed the financing for $8 million in gross proceeds in a private placement priced at the market per NASDAQ rules. With additional resources in place, we have begun dosing patients in the Phase II proof-of-concept part of our 065-101 study, evaluating fadraciclib of fadra for short in patients with 1 or more chromosomal abnormalities, including CDKN2A and/or CDKN2B deep deletions or loss of function.
You will recall that we are pursuing a potential precision medicine approach for fadra, an oral CDK2/9 inhibitor following findings in our clinical and preclinical data, which suggests the hypothesis that patients with one or more of these chromosomal abnormalities maybe sensitive to fadra. In the Phase II part, we are evaluating patients selected for their mutational profile and/or Phase I activity in various solid tumors and lymphoma. We're initially enrolling 2 patient cohorts, those with CDKN2A and/or CDKN2B abnormalities and also T-cell lymphoma based on observation of anticancer activity, including responses in multiple Phase I patients.
We believe that there is great unmet medical need and industry interest in the cancer patient populations identified by these abnormalities, which are closely located on chromosome 9 and are often co-deleted. CDKN2A gene deletions occur in several solid tumors, including bladder, breast, endometrial, esophageal, glioma, head and neck, hepatobiliary, lung, including squamous, melanoma, ovarian, pancreatic and also in certain T-cell lymphomas.
CDKN2B deletions occur in several solid tumors, including bladder, breast, cholangiocarcinoma, endometrial, esophageal, glioma, head and neck, hepatobiliary, lung, including squamous and mesothelioma, melanoma, pancreatic and others. There are no approved drugs to treat patients with CDKN2A or B abnormalities. We expect 2 key data readouts for fadra this year. Final data from the dose escalation part of the 065-101 study to be presented at the ASCO 2024 Annual Meeting in a few weeks and support on initial clinical activity from the Phase II proof-of-concept part of the study in the second half of this year.
I will now turn the call over to Brian to review our progress and discuss some of our clinical results in the fadra study. Brian?
